[0002] An elevator is a mechanical device used for vertically transporting objects or people, usually consisting of one or more elevator cars and an operating track. It can work between different floors in a building or in the up and down directions outside the building. The operation of the elevator is usually automatic or can be manually operated through a manual control panel.

[0003] When an elevator is in use, a roller structure is required to guide the cargo box during lifting. However, during the use of the existing roller structure, usually a few rollers are arranged on the outside of the cargo box to guide the lifting of the cargo box. However, when a single roller is damaged, it will affect the overall operation of the elevator and the stability of the cargo box lifting. The existing rollers are usually made of metal, and the replacement cost of the metal rollers is relatively high. Moreover, the rollers are usually installed on the outside of the cargo box by welding. After long-term use, the surface of the rollers will wear, so the rollers need to be replaced in time. However, the welded rollers are not easy to disassemble and replace, which affects the normal operation of the elevator.
