[0002] A hoisting chain for a hoist with the publication number of CN213235949U includes chain plates, connecting columns, connecting sleeves, pull plates and magnetic clamping plates. The number of chain plates is multiple. Circular through holes are opened at both ends of the multiple chain plates. The multiple chain plates are connected into a chain structure through the circular through holes and the connecting columns. A pull plate is arranged on one end of the connecting column passing through the chain plate, and a magnetic clamping plate is slidably connected inside the pull plate. When in use, first, the pull plate is sleeved on two adjacent connecting columns through fixing holes, and then the magnetic clamping plate is slid outwards from the inner side wall of the fixing hole, so that the magnetic clamping plate is adsorbed inside a clamping groove opened on the connecting column through the action of magnetic force, avoiding the sliding of the connecting column, and at the same time, the pull plate can be clamped on the connecting column. By sleeving a pull plate on one end of the connecting column passing through the chain plate, it is used to reinforce the weak part at the connection between the connecting sleeve and the chain plate, avoiding the problem that the chain plate breaks from the circular through holes opened at both ends due to the tensile force.

[0003] When the above-mentioned hoisting chain for a hoist is actually used, the chain is not convenient to disassemble and assemble, which is not conducive to subsequent regular maintenance and repair of the chain, and the length of the chain is not convenient to adjust.
