As technology advances, machine gun weapon stations are used. Because the weapon is remotely operated to shoot in the vehicle, the danger that soldiers are exposed outside the vehicle is reduced, the soldiers can be protected, casualties are reduced, and the shooting precision and the combat efficiency of the weapon can be improved. However, when the weapon station shoots, the weapon can discharge the shot chain strings after the shooting is taken off from the station body, and the shot chain strings must be orderly discharged according to a certain direction when being discharged, which is more important particularly when the weapon is shot upward, otherwise, the shot chain stacking can occur, so that the shooting jamming and the empty chamber failure of the weapon can be caused, and the normal use of the weapon station can be influenced. In order to ensure the adaptability of the weapon and the weapon station and improve the reliability of the weapon, a special chain guide device for the weapon station must be designed, so that the smooth and smooth chain arrangement of the ammunition chain is ensured during the shooting of the weapon, the ammunition supply of the weapon is reliable and timely, and the maintenance is simple.

Detailed Description

Referring to fig. 1, the chain guide device for the flip non-return weapon station is disclosed.

Referring to fig. 2, the cover plate body 2 is sleeved on the hinge shaft through the hinge pipe arranged on the cover plate body, the non-return spring provides axial pressure to the hinge pipe, and the cover plate body 2 is prevented from rotating through friction force.

The cover plate body 2 and the hinge seat 14 are provided with two side walls with thickness, under the locking state, the two side walls of the cover plate body 2 and the hinge seat 14 are corresponding and are abutted, the two side walls of the hinge seat 14 form a first acting surface, under the opening state, the two side walls of the cover plate body 2 and the hinge seat 14 are staggered, one side wall of the cover plate body 2 is abutted on a second acting surface arranged on the hinge seat 14, and the wall surfaces of the two side walls of the cover plate body 2 and the hinge seat 14 are abutted.

Referring to fig. 2, the cover plate body 2 passes through a first acting surface formed with the hinge base 14, and since the axis of the hinge shaft 15 is at a middle position of the acting surface, the cover plate body 2 is restricted from rotating by means of the acting surface. When the cover plate body 2 of the flip cover non-return mechanism is opened, the cover plate body 2 of the flip cover non-return mechanism is pulled backwards by about 5 mm, meanwhile, the cover plate body 2 rotates around the hinge shaft 15 by about 92 degrees in the anticlockwise direction, at the moment, the cover plate body 2 and the hinge seat 14 remove the limitation of the first action surface and form a second action surface (the cover plate body 2 can be limited to rotate by the action surface because the axis of the hinge shaft 15 is in the middle position of the action surface), and the second action surface enables the cover plate body 2 to keep an opened state and not to automatically rotate; when the cover plate is closed, the cover plate body 2 is pulled backwards by about 5 mm and simultaneously rotates around the hinge shaft 15 by about 92 degrees clockwise, the cover plate body 2 can automatically reset under the action of the check spring 10, at the moment, the cover plate body 2 and the hinge seat 14 remove the limitation of the second action surface and form a first action surface, the check action is realized under the action of the first action surface, and the cover plate body 2 is prevented from being opened under the action of the elastic chain string 16 in a counterclockwise rotation mode.

Referring to fig. 3, the bullet chain string 16 is output from a weapon 17 outlet, slides downwards along the lower surface of the cover plate 2 under the lifting action of the cover plate 2 and the middle guide rail 6, at the moment, the left side surface and the right side surface of the middle guide rail 6 restrain the middle part of the bullet chain string 16 and reduce the left-right swing of the bullet chain string, and the heads of the left guide rail 4 and the right guide rail 8 can also assist in acting on the bullet chain string to assist the bullet chain string 16 to move towards the inside of the guide chain device; after the ammunition chain string 16 moves for a certain distance, the left and right lugs of the ammunition chain string 16 are in contact with the straight line sections of the left guide rail 4 and the right guide rail 8 of the chain guide device, the ammunition chain string 16 continues to move downwards under the combined constraint of the left guide rail 4, the right guide rail 8 and the upper plate 12 of the chain guide device, and the ammunition chain is guaranteed to be always in a constraint state under different shooting postures of the weapon station and smoothly discharged downwards out of the weapon station. The whole chain guide device is fixed on a weapon station through the left connecting seat 1 and the right connecting seat 9, and the installation height can be adjusted at will. The left and right guide rails are composed of a supporting plate and a steel wire slide rail.

The working process is as follows:

the whole chain guide device is fixed on a weapon station through a left connecting seat 1 and a right connecting seat 9, and in a weapon station combat preparation stage, a cover plate body 2 of a flip non-return structure is opened firstly, and a weapon is installed; after the weapon is mounted, the cover plate body 2 is closed, so that the chain outlet of the weapon is opposite to the chain guide device inlet. When a weapon is fired, the bullet chain string 16 is discharged from a weapon chain outlet and is input into the chain guide device, wherein the bullet chain string 16 firstly contacts the cover plate body 2 and is transported to the inside of the main cavity body under the action of the cover plate body 2, meanwhile, the middle guide rail 6 of the chain guide device contacts the middle part of the bullet chain, the bullet chain is lifted upwards, the swinging of the bullet chain is limited left and right, the bullet chain is enabled to move downwards smoothly, when the middle position of the chain guide device is reached, the left guide rail 4 and the right guide rail 8 respectively restrain the left lug and the right lug of the bullet chain string 16 to guide the bullet chain to move downwards, under the auxiliary action of the upper plate 12 of the main cavity body, the bullet chain string 16 is guided to be discharged downwards out of the weapon station, and when the weapon station is fired, no chain jamming or empty chamber fault exists in.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
