Abstract

It relates to the anti clamping device for the automatic sliding door of lifters. It comprises the main frame, hinges, rotary corner steel, inching switch and reset spring, with the hinge fixed with the main frame and rotary corner steel respectively, with the rotary corner steel rotates around the main frame, inching switch and the reset spring on the main frame and the rotary corner steel driving the inching switch to motion. This simple, convenient and reliable device solves the clamping issue of lifter sliding doors, eliminating potential risks in national lifter regulations.

Description

technical field [0001] The invention relates to an anti-pinch device, which is mainly used for automatic sliding doors of elevators. Background technique [0002] Article 7.5.1 of GB7588-2003 "Safety Code for Elevator Manufacturing and Installation" stipulates: "The design of the landing door and its surroundings should minimize the risk of damage or injury caused by people, clothes or other objects being caught. In order to avoid Risk of shearing during operation, power-operated automatic sliding doors shall have no recesses or protrusions greater than 3 mm on the outer surface, and the edges of these recesses or protrusions shall be chamfered in the direction of door opening travel". Since there is still a certain movement gap between the door leaf and the column, Article 7.1 of GB7588-2003 "Safety Code for Elevator Manufacturing and Installation" also stipulates: "For passenger elevators, this movement gap shall not be greater than 6mm. For cargo elevators, this gap shal...
