AI Technical Summary
During use, the counterweight assembly of existing elevators suffers from poor limit stability due to loose nuts, which in turn causes wear on the counterweight.
The counterweight is positioned and limited by positioning and limiting components. The limiting components have a self-locking function. The stability of the counterweight is achieved by the cooperation of the limiting rod and nut, combined with the worm gear structure. The stability is further improved by the sliding groove on the inner side of the support plate.
This effectively prevents the weight from loosening and wearing out, improves the stability of the limit switch, and ensures the stability and durability of the elevator operation.
