[0039] Working principle and usage process of the utility model: When the trolley frame 2 is connected to the anti-derailment structure body 3 during use, the positioning block 41 can move into the positioning groove 42. The positioning block 41 can limit the movement of the anti-derailment structure body 3 through the positioning groove 42, so that the anti-derailment structure body 3 is stably limited at the bottom of the trolley frame 2. The meshing plate 43 can enhance the connection tightness between the bottom of the trolley frame 2 and the anti-derailment structure body 3, avoiding the situation of unstable connection due to connection gaps. The connection groove 44 can facilitate the movement of the positioning block 41. The movable groove 51 is internally threadedly connected with a moving rod 52 during use. During use, after the positioning block 41 moves into the positioning groove 42, the moving rod 52 can be rotated to make the moving rod 52 rotate and move inward through threaded transmission with the movable groove 51. The movement of the moving rod 52 can move into the fixed groove 53 to limit the movement of the positioning block 41, enhancing the fixing convenience of the positioning block 41. The spring 6 can elastically push the limiting block 55 during use, so that the limiting block 55 stably moves into the limiting groove 54 to limit the movement of the inner side of the positioning block 41, and can also avoid the situation of the limiting block 55 being separated from the positioning groove 42 during movement. During disassembly, only the moving rod 52 needs to be reversed to make the moving rod 52 separate from the inner side of the positioning groove 42 through threaded transmission with the movable groove 51, and then the moving block 10 is used to drive the movable plate 9 and the limiting block 55 to move and separate from the limiting groove 54, achieving the effect of facilitating disassembly, installation and maintenance, and enhancing the use effect of the anti-derailment structure.
