Background

In the communication network laying engineering, a network optical cable is generally laid in a pipe gallery in a medium-large city, however, in vast medium-small cities and rural areas, a high-altitude erection mode can be adopted, the optical cable erection in the prior art is generally suspended and fixed by means of steel stranded wires and hooks or buckles, the top ends of the hooks or the buckles are hung on the steel stranded wires, and the network optical cable is placed on the hooks or the buckles.

The hook commonly used in the prior art is generally in a V-shaped structure, two ends of the hook are top hooks hung on steel strands, and the middle part of the hook is sunken downwards to support the network optical cable. In addition, in order to increase the contact area of the hooks and the network optical cable, widening pieces are additionally arranged at the concave middle parts of the hooks, so that the phenomenon that the contact parts of the network optical cable and the hooks are damaged or cut off due to excessive pressure is avoided.

Buckle among the prior art is comparatively similar with foretell couple structure, like the utility model discloses a convenient high altitude optical cable of erectting of patent number 201921629672.3, the optical cable outside is equipped with the buckle, as shown in fig. 1, the crisscross two configuration structures that are equipped with in both ends of buckle, the bayonet socket joint that two configuration structures constitute is on the steel strand wires to realize the fixed of optical cable.

However, these hooks or clasps have several problems during use: 1. it is inconvenient to construct. During the process of laying the network optical cable, a large number of hooks or buckles (for example, one hook is arranged at intervals of 30-50cm, which is determined according to the number of the network optical cables supported by the hooks), so that a constructor needs to firstly place the network optical cable on the hook, or fold the network optical cable and the steel stranded wire together by hands, and then hang the hook on the steel stranded wire. According to the construction steps, the network optical cable and the steel strand are folded together, so that the weight can be greatly increased, subsequent hook action is inconvenient, and the labor intensity of constructors is increased. 2. The optical cable is inconvenient to increase and decrease and maintain in the later period. If an optical cable line needs to be additionally hung in the later period, all the hooks or the buckles need to be completely taken off, and then the optical cable is hung and then hung again, so that the process is extremely complicated. 3. Part of the hooks or the buckles have insufficient strength and are not stably hung. Some hangers cannot be firmly hung on a steel strand due to unreasonable hanger structure, so that the hangers are easy to fall off in outdoor environments such as strong wind or under heavy load. 4. And part of the hooks have complicated structures and high cost. Some hooks are complicated in manufacturing process due to the fact that widening pieces are additionally arranged, even manual installation is needed, the production cost of a single hook is greatly increased, a large number of hooks are needed for laying network lines, and high cost and resource waste are caused. 5. The load bearing capacity of part of the hook is smaller. 6. The structure of part couple is unreasonable, can only artifical manual construction, and the work progress is comparatively wasted time and energy.

The two support arms of the optical cable hanging protection hook in the embodiment of the invention are in a vertical crossing state with the main body hook part 30, so that the optical cable lines can be in the same straight line. In addition, the configuration structure of the optical cable hanging protection hook is also beneficial to maintaining the hanging stability of the optical cable hanging protection hook on the steel strand and facilitating the attaching and hanging process during construction.

In some embodiments, as shown in fig. 2, 3, 4 and 5, to show the structure of the first arm 10, fig. 5 is a cross-sectional view a-a of fig. 3, the first arm 10 includes a first top hook and a first top hook connecting section 14, the first top hook includes a first top hook lower folded section 11, a first top hook width section 12 and a first top hook upper folded section 13, and the first top hook upper folded section 13 is adjacent to the first top hook connecting section 14.

The outer side mentioned here is a direction away from a symmetrical plane of the cable suspension hook, and the front and rear means a direction with the main body hook portion 30 as the front and the two arms as the rear.

In some embodiments, as shown in fig. 2, 3, 4 and 6, to show the structure of the second arm 20, fig. 6 is a cross-sectional view of C-C of fig. 3, the second arm 20 including a second top hook and a second top hook attachment section 24, the second top hook including a second top hook lower fold section 21, a second top hook width section 22 and a second top hook upper fold section, the second top hook upper fold section and the second top hook attachment section 24 being contiguous. The second top hook upper folding section of the second top hook is deflected towards the inner side relative to the extending direction of the second top hook upper folding section, the width of the second top hook width section 22 is greater than or equal to the diameter of the steel strand, the second top hook lower folding section 21 is deflected towards the rear side relative to the reference plane, and the length of the second top hook lower folding section 21 is longer than that of the second top hook upper folding section. The inner side is a direction close to a symmetrical plane of the cable suspension hook, and the front and rear are directions in which the main body hook portion 30 is front and the two arms are rear.

In the above embodiment, the first top hook is substantially along the direction of the reference plane, or has an included angle of a small angle (for example, 0 to 20 °) with the reference plane; the second top hook is approximately perpendicular to the reference plane, or has the contained angle of big angle (for example 70 ~ 90 °) with the reference plane for first top hook and second top hook are installed on the steel strand with the state of crisscross each other, can firmly lock on the steel strand, strengthen its stability greatly.

In addition, the first top hook and the second top hook are both in flaring structures, so that the hooking process in the installation process is facilitated. The bottom of the structure is approximately equal to the diameter of the steel strand, namely the lengths of the first top hook width section 12 and the second top hook width section 22 are approximately equal to the diameter of the steel strand, so that the two structures are firmly clamped on the steel strand. The first top hook upward-folding section 13 and the first top hook connecting section 14 have a certain inclination angle, the second top hook upward-folding section and the second top hook connecting section 24 have a certain inclination angle, and the first top hook upward-folding section 13 and the second top hook upward-folding section are both deflected towards the inner side, so that the stability of two configuration structures on the steel strand is kept, and the steel strand is prevented from being popped out and sliding. The second top hook lower folding section 21 of the second top hook is approximately deflected towards the rear side, so that the second top hook can enter the steel strand more easily in the installation process.

In some embodiments, as shown in FIG. 2, the node structure 31 of the first arm 10 and the second arm 20 is a single-line spiral structure including the spiral segment 15 of the first arm 10 and the core segment 25 of the second arm 20. The inner core segment 25 of the second arm 20 is concavely bent towards the direction of the first arm 10, and the spiral segment 15 of the first arm 10 is wound on the outer periphery of the inner core segment 25 of the second arm 20. The optical cable hanging protection hook is formed by bending an elastic wire, the node structure 31 of the first support arm 10 and the second support arm 20 is of a single-wire spiral structure, namely one support arm is spirally wound on the other support arm, one support arm is in front, the other support arm is behind, the two support arms are arranged in a staggered mode, the elasticity of the staggered structure can be enhanced, and the staggered structure can be firmly clamped on a steel strand. The single-wire spiral structure is beneficial to enhancing the elasticity of the two support arms which are arranged on the steel strand in a staggered mode. In addition, the single-wire spiral structure is more stable and more reasonable in stress compared with a double-spiral structure, the automatic manufacturing process of the optical cable hanging protection hook is simplified, the forming and the structural stability during manufacturing are facilitated, and the manufacturing cost and the manufacturing process are reduced by the structure.

Preferably, the first arm 10 is located at the rear side of the second arm 20, and the elastic line segment of the body hook 30 adjacent to the first arm 10 extends from the front side of the bottom end of the node structure 31 and is deflected to the same side (as the left side in fig. 2) as the first arm 10. In other words, the spiral section 15 of the first arm 10 can be spirally wound for (N +0.5) turns, that is, the elastic line section is located at the rear of the first arm 10 and at the front of the main body hook 30, and the staggered structure can ensure the stability of the whole cable suspension protection hook and prevent the cable suspension protection hook from being scattered and structurally displaced in the construction process.

Further preferably, the elastic line segment of the body hook 30 adjacent to the inner core segment 25 of the second arm 20 is bent from the bottom end of the node structure 31 toward the second arm 20, and the bent portion is used for catching the bottom end of the spiral segment. As shown in fig. 1 and 2, it can be seen that the elastic line segment of the second arm 20 is bent in the node structure 31, i.e. the inner core segment 25 is bent in the direction of the first arm 10, the concave portion is used for winding the spiral segment of the first arm 10, and the upper and lower bent portions of the concave portion are used for abutting against the upper and lower turns of the spiral segment, so as to prevent the spiral segment from sliding or loosening on the elastic line segment of the second arm 20, thereby preventing the structure thereof from being unstable.

The width of the hook part 30 of the main body can be gradually widened from the node structure 31 to the tail end 33, the tail end 33 which is tilted upwards is beneficial to keeping the rigidity of the tail end structure, and the hook part can also be used as a bending stress point in the manufacturing process so as to facilitate production.

Preferably, the width of the double-row line of the hook part 30 of the main body is 7-18 mm, so that the contact area of the hook part and the optical cable is enlarged, the optical cable is prevented from being cut, and the stable bearing is facilitated.
