The quick release mechanism includes a plurality of sets of quick release assemblies, each set of quick release assemblies including a stop 400 and a bolt assembly 300.

The bolt assembly 300 is composed of a bolt 310 and a nut 320; when the connecting structure is used, the T-shaped bolt 310 and the ring nut 320 are mutually matched and connected with the baffle seat to form a detachable connecting structure.

In this embodiment, referring to fig. 3, T-bolts 310 are installed at both sides of the carrier roller group 200. One end of the screw rod is a screw rod end 311, in particular to a thread structure, and the screw rod is used for being connected and fixed with a nut; the other end is a stop 312 for connection with the stop seat.

The protruding portions 3121 are disposed on two sides of the stop block 312, and the stop block can be used to cooperate with the stop block 400 to enable the stop block 400 to be quickly fixed and detached from the bolt 310 after the stop block is rotated by a certain angle from the first position to the second position. The specific mating relationship of the bolt 310 to the retainer 400 is described below in the context of the retainer configuration.

The nut 320 is arranged at the screw end 311 of the T-shaped bolt; after the stop block 312 of the T-bolt is fixed with the stop seat 400, the T-bolt 310 is tightened or loosened by the nut 320 to fix and detach the intermediate frame upper carrier roller set 210 and the H-bracket 100.

In the present solution, referring to fig. 4, the nut 320 is preferably a ring nut, and the nut 320 has a ring 321, which is convenient for a user to lock the nut 320, so as to improve the comfort of the user.

The stopper 400 is welded to the middle frame 500, and has a hollow structure therein for receiving the bolt assembly 300.

Referring to fig. 5-6, a lock hole is formed in the middle of the stopper seat 400, and an inner cavity of the lock hole is matched with the T-core bolt 310; the aperture of the port 420 at one end of the lock hole is larger than the aperture of the screw 311 of the bolt and smaller than the aperture of the bolt stop block 312, so that the screw 311 can pass through, and the aperture of the port 410 at the other end of the lock hole is larger than the aperture of the stop block 312; the stop 312 may be inserted into the stop seat 400 when the T-bolt 310 passes through the stop seat 400.

Meanwhile, two clamping positions 410 are symmetrically arranged inside the retaining seat 400 and used for limiting the rotating angle of the T-shaped bolt, and the T-shaped bolt can be fixed and detached by being matched with the T-shaped bolt.

In the scheme, the baffle seat 400 is preferably welded on two sides of the middle frame 500 by adopting precision casting cast steel, so that the connection between the baffle seat and the carrier roller set is firmer; and the material of keeping off seat 400 has the advantage that intensity is high, can make the bearing roller group more stable at the operation in-process.

When in use, the T-shaped bolt 310 is inserted into the baffle seat 400 and connected with the baffle seat 400;

referring to fig. 6, the screw end 311 of the bolt is inserted through the notch of the stopper 400, and the stopper 312 of the bolt is inserted into the stopper 400; at this time, the protruding portion 3121 of the T-bolt is away from the position of the detent 410 inside the stop seat 400; when the T-shaped bolt rotates clockwise by 90 degrees, the protruding portion 3121 of the T-shaped bolt stopper and the blocking position 410 inside the blocking seat 400 are respectively clamped and fixed, and at this time, the T-shaped bolt 310 cannot be pulled out; when the T-bolt 310 rotates 90 degrees counterclockwise, the protruding portions 3121 of the two sides of the stop block of the T-bolt 310 are separated from the retaining portion 410 inside the retaining base 400, and the T-bolt 310 can be pulled out, and the T-bolt 310 and the retaining base 400 can be fixed and detached by the design.

For example, the inner wall of the inner cavity of the end 420 close to the large aperture of the lock hole is symmetrically provided with the blocking parts 410; the blocking position can be an arc-shaped groove 410, the diameter of a first contact opening when the arc-shaped groove 410 is matched with the T-shaped bolt 310 is larger than the protruding portions 3121 on two sides of the T-shaped bolt blocking seat, and the protruding portions 3121 of the T-shaped bolt can enter the arc-shaped groove 410.

Further, in the orientation where the arc-shaped groove 410 rotates along the T-bolt 310, the inner diameter of the arc-shaped groove 410 gradually decreases until the diameter is smaller than the protruding portion 3121 of the T-bolt; when the T-bolt protrusion 3121 enters the arc groove 410, it continues to rotate clockwise by external force, and the T-bolt 310 can be clamped in the arc groove 410 because the diameter of the inside of the arc groove 410 is gradually reduced to be smaller than the diameter of the T-bolt protrusion 3121.

When the T-shaped bolt rotates counterclockwise, the protruding portion 3121 of the T-shaped bolt can be moved from the portion with small diameter of the arc-shaped groove 410 to the portion with large diameter of the arc-shaped groove 410 by external force, and then can be separated from the arc-shaped groove 410, and the T-shaped bolt 310 and the baffle base 400 can be detached.

Specifically, the straight rod end of the handle is inserted into the annular ring 321 of the ring nut 320 to rotate at a certain angle, so that the fastened T-shaped bolt 320 can be loosened; the T-shaped bolt 320 is loosened through the handle, and the effects of saving time and labor are achieved.

Meanwhile, referring to fig. 8, a pin shaft end 620 is inserted into a positioning hole on the middle frame 500, the distance between the end surface of the handle end 610 of the deviation adjusting tool and the end surface of the roller frame is 1-2 mm, the distance between the end surface of the handle end 610 and the end surface of the roller frame is reduced by rotating the handle end 610 with the pin shaft as a fulcrum, and the roller frame is tilted to move back and forth by continuing to rotate, so that the deviation adjusting purpose is achieved.

Furthermore, the positioning holes are positioned on the middle frames 500 arranged at the two sides and are respectively distributed at the front end and the rear end of each side of the carrier roller group arranged on the middle frames; each carrier roller group can move back and forth at each end of the carrier roller group through four positioning holes.
