Longitudinal opening and closing type landing door opening protection device

Abstract

The invention discloses a longitudinal opening and closing type landing door opening protection device. The longitudinal opening and closing type landing door opening protection device comprises a door vane and a car door blocking rod which are mounted on a car door assembly, and a landing door lock assembly mounted on a landing door assembly, wherein a longitudinal opening and closing type clamping assembly is arranged on the landing door assembly. The longitudinal opening and closing type clamping assembly mainly consists of a first clamping part and a second clamping part, wherein the first clamping part mainly consists of a first base, a first clamping jaw, a first spring, a first rolling wheel and a manual unlocking piece; and the second clamping part mainly consists of a second base, a second clamping jaw, a second spring, a second rolling wheel and a limiting block. Through the adoption of the longitudinal opening and closing type landing door opening protection device disclosed by the invention, an elevator triangular key owner can be effectively protected when opening an elevator landing door, and besides, the normal opening and closing of the elevator landing door can be guaranteed when the elevator is in the normal operation state.

Description

technical field [0001] The invention relates to an elevator landing door opening protection device, in particular to an up and down opening and closing type landing door opening protection device that provides necessary prompts for special operators when they enter the car and can provide safety protection.
