The positioning wheel disc 14 is circumferentially provided with a limiting groove 140, and the positioning wheel disc 14 is fixedly installed in the positioning hole 12 through the limiting groove 140 and the cooperation of a limiting rod 141 and a screw rod 142 arranged on the lock body 1.

[0031] When the spring is in a natural state, the outer end of the limiting button 3 protrudes and is clamped into the limiting groove 210 to limit the circumferential rotation of the lock pin 2.

[0032] When it is necessary to rotate the lock pin 2, the user presses the limiting button 3 with one hand and rotates the lock pin 2, so that the limiting pin 11 slides from the annular lock groove 200 into the strip-shaped groove 201, that is, the lock pin 2 can be axially pulled out to complete unlocking; when the reverse operation is performed, the limiting pin 11 is embedded in the annular lock groove 200 to form rigid locking.

[0033] The annular lock groove 200 is arranged on the lock rod 20 close to the lock cap 21, one end of the strip-shaped groove 201 is through the annular lock groove 200, and the other end of the strip-shaped groove 201 extends away from the lock cap 21 to form a closed stop end 202, which can ensure that the limiting pin 11 is still limited in the strip-shaped groove 201 in the unlocked state, prevents the lock pin 2 from being completely pulled out or falling off, and fundamentally eliminates the hidden danger of component loss.

[0034] The lock body 1 is provided with a pin hole 15, the pin hole 15 is through from the outside of the lock body 1 to the mounting hole 10, one end of the limiting pin 11 is arranged in the pin hole 15, and the other end of the limiting pin 11 extends into the mounting hole 10 and is limited in cooperation with the annular lock groove 200 and the strip-shaped groove 201, and the limiting pin 11 and the pin hole 15 can be threadedly connected, which is convenient for disassembly, maintenance or adjustment.

[0035] In combination Figures 3 to 5This utility model also provides a force-sharing plate with the aforementioned locking pin structure, including a plate body 4, a lock body 1, and a locking pin 2. The lock body 1 is disposed on the plate body 4, specifically connected to a position on the lower side of the plate body 4 near one end. The locking pin 2 includes a locking rod 20 and a locking cap 21 disposed at one end of the locking rod 20. The lock body 1 has a mounting hole 10 for the locking rod 20 to pass through, and the locking rod 20 is inserted into the mounting hole 10. The outer diameter of the locking rod 20 matches the diameter of the mounting hole 10, and the outer diameter of the locking cap 21 is larger than the outer diameter of the mounting hole 10. An annular locking groove 200 is provided circumferentially on the locking rod 20, and a strip groove 201 is provided axially on the locking rod 20. The annular locking groove 200 and the strip groove 201 are connected to form a limiting path. A limiting pin 11 is provided in the lock body 1 to cooperate with the annular locking groove 200 and the strip groove 201. A support body 41 is also provided on the plate 4. The support body 41 has a lock hole 410 that is coaxial with the mounting hole 10 and mates with the locking rod 20, i.e., the lock hole 410 through which the locking rod 20 passes. After the locking rod 20 passes through the mounting hole 10 and the lock hole 410, a lifting hole 42 is formed between the plate 4, the lock body 1, the support body 41, and the locking rod 20, and the locking pin 2 can be used as a load-bearing rod.

[0036] In use, the user can rotate the locking pin 2 and apply axial pulling / pushing to adjust the engagement between the limiting pin 11 and the locking rod 20, so that the limiting pin 11 is within the annular locking groove 200 or the strip groove 201. When the limiting pin 11 is limited within the annular locking groove 200, the annular locking groove 200 restricts the axial displacement of the locking pin 2. At this time, the locking pin 2 is stuck in the lock body 1 and cannot be pulled out, thus being in a locked state. Rotating and pulling the locking pin 2 outward causes the limiting pin 11 to disengage from the annular locking groove 200 and enter the strip groove 201, thereby releasing the axial limitation of the locking pin 2 and allowing it to be pulled out for unlocking.

[0037] This utility model discloses a force-sharing plate with a locking pin structure. The locking pin structure is integrated into the force-sharing plate. The locking pin structure can directly replace traditional external connecting devices such as buckles, reducing the force-sharing plate's dependence on external connecting parts. At the same time, the modular integration reduces the number of devices carried by the user, making it particularly suitable for scenarios requiring lightweight equipment, such as high-altitude rescue and complex terrain rock climbing.
