Anti-shock device for elevator descent

Abstract

This invention provides an anti-impact device for elevator descent, belonging to the field of elevator technology. It includes a main body comprising a base, an outer shell I mounted on the upper part of the base, an outer shell II mounted on the upper part of the outer shell I, an outer support ring mounted on the side of the outer shell II, and a support rod I slidably connected to both the outer shell I and the outer shell II. A support tray is mounted on the upper part of the support rod I, and a rotating disk is rotatably connected to the lower part of the support tray. A spring I is installed between the rotating disk and the outer support ring, located outside the support rod I. This invention solves the problems that the impact resistance of anti-impact devices is essentially constant and cannot be changed according to needs, and that exposed components may accumulate impurities during long-term use, potentially causing operational stagnation and affecting the impact resistance effect.
