[0027] The limiting mechanism includes a transmission shaft core 3 arranged in the pin shaft body 2, one end of the transmission shaft core 3 extends out of the pin shaft body 2, and the other end of the transmission shaft core 3 is transmission-connected to a limiting component, which is movably connected to the pin shaft body 2 and is limitedly connected to the hanging buckle 1;

[0028] The limiting assembly includes two baffles 4 symmetrically slidably connected to the pin shaft body 2 . The baffles 4 are telescopically arranged on the pin shaft body 2 , and the baffles 4 and the hanging buckle 1 are limitedly arranged.

[0029] The utility model discloses a quick-loading and disassembling pin, which is mainly used in a working environment where loading and unloading are often performed, and realizes the function of quick disassembly and assembly between the suspended object and the lifting rigging; when in use, the pin body 2 is inserted into the hanging buckle 1, and the hanging buckle 1 is closed to realize the connection between the suspended object and the lifting lock; the limit assembly clamps the hanging buckle 1 to prevent the pin body 2 from being separated from the hanging buckle 1; and when the suspended object needs to be separated from the lock, the transmission shaft core 3 is rotated to make the baffle 4 extending out of the pin body 2 retract into the pin body 2, so that the pin body 2 can be disengaged from the hanging buckle 1, which is convenient for separating the suspended object and the lock, and realizes quick disassembly and assembly between the suspended object and the lifting rigging; at the same time, the limit mechanism is integrated in the pin body 2, which is easy to operate, and can also effectively reduce the risk of loss of parts and components, thereby extending the service life of the pin. The utility model has a simple structure, is easy to operate, realizes quick disassembly and assembly between the suspended object and the lifting rigging, meets the requirements of quick loading and unloading, improves work efficiency, reduces labor intensity, and can also effectively avoid the loss of parts and components, thereby extending the service life of the pin.

[0030] In a further optimized solution, a transmission gear 5 is provided on the transmission shaft core 3, and transmission racks 6 are respectively engaged on both sides of the transmission gear 5, and the ends of the two transmission gears 5 that are away from each other are respectively fixed to a baffle 4. The transmission shaft core 3 drives the transmission gear 5 to rotate, and then the baffle 4 is driven to move through the transmission rack 6 engaged with the transmission gear 5, so that the two baffles 4 can symmetrically extend and slide on the pin shaft body 2, and the pin shaft body 2 can be clamped in the hanging buckle 1.

[0031] In a further optimized solution, a positioning nut 7 is embedded and fixedly connected to one end of the pin shaft body 2 close to the baffle 4, and a positioning screw 8 threadedly connected to the positioning nut 7 is provided on the transmission shaft core 3, and the positioning screw 8 is threadedly connected in the positioning nut 7.

[0034] In a further optimized solution, a torsion spring 10 is sleeved on the transmission shaft core 3, one end of the torsion spring 10 is clamped with the pin shaft body 2, and the other end of the torsion spring 10 is clamped with the transmission shaft core 3.

[0035] Further optimizing the scheme, a control wrench 11 is fixedly connected to one end of the transmission shaft core 3 away from the baffle 4. The control wrench 11 is fixedly connected to the transmission shaft core 3, and as the fulcrum of the transmission shaft core 3, the transmission shaft core 3 can be driven to rotate by a simple tool, which is simple and labor-saving.

[0036] In a further optimized solution, the transmission shaft core 3 includes a prismatic body 12, which is plugged into the hook 1; an end block 13 is fixedly connected to one end of the body 12, the end block 13 abuts against the hook 1, and the transmission shaft core 3 extends out of the end block 13. In order to prevent the pin shaft body 2 from rotating in the hook 1 during use, the body 12 can be set to a prismatic shape, and the through hole of the hook 1 is adapted to the body 12; the outer diameter of the end block 13 is larger than the through hole of the hook 1, and the body 12 is positioned in combination with the baffle 4 to prevent the pin shaft from falling off.

[0037] Further optimizing the scheme, a handle 14 is fixedly connected to one end of the end block 13 away from the body 12. The setting of the handle 14 is mainly to facilitate the installation and removal of the pin shaft, and it is more convenient to use; at the same time, a fixing rope can be tied to the handle 14 to prevent loss.
