CN-119911776-B - Welding-free adjustable support and elevator guide rail mounting structure

Abstract

Compared with the prior art, the welding-free adjustable support frame does not depend on friction force to resist the force born by an elevator guide rail, the structural strength of the welding-free adjustable support frame is designed to bear the force born by the elevator guide rail through the support leg, the connecting plate and the connecting structure between the support leg and the connecting plate, welding is not needed between the support leg and the connecting plate, the installation complexity is reduced, the installation efficiency is improved, the position of the connecting plate can be adjusted through the first limiting ring and the second limiting ring, and therefore the elevator guide rail can be conveniently adjusted. The elevator guide rail mounting structure is free of welding, low in mounting complexity and high in mounting efficiency, and when the elevator guide rail needs to be adjusted, a supporting frame does not need to be damaged, the adjusting speed is high, and the adjusting operation is simple.
