Rotary wing anti-pinch door leaf of two-wing rotary door

Abstract

The invention discloses a rotary wing anti-pinch door leaf of a two-wing rotary door. The rotary wing anti-pinch door leaf of the two-wing rotary door comprises a top cover mounted on a ceiling, a fixed door leaf and a rotary door leaf, the rotary door leaf comprises a spacing board and a rotary arc door leaf, the rotary arc door leaf comprises a rear end arc door leaf, a middle arc door leaf anda front end arc door leaf which are connected in sequence, the rear end arc door leaf is fixedly connected with the middle arc door leaf, and the top of the front end arc door leaf is hinged to the top cover. According to the rotary wing anti-pinch door leaf of the two-wing rotary door, an induction system is arranged more reasonably, stops rotating after a person is pinched, the front end arc door leaf in the rotary door leaf can be pushed up inwards under the action of external force, so that a living space appears at the person-pinched position, and the pinched person can smoothly evacuate.

Description

technical field [0001] The invention relates to the field of revolving doors, in particular to a two-wing revolving door anti-clamping door leaf of the revolving wings. Background technique [0002] Automatic revolving doors are widely used in the passages of various halls, halls, shopping malls and other large places. Its structure mainly includes: fixed door leaf, revolving door leaf, driving device and control system for driving the revolving door leaf. Among them, the revolving door leaf is hoisted in the fixed door leaf, and after being driven and rotated by the central shaft and the driving device, the normal passage of passing pedestrians is realized, and the automatic opening or closing function of the gate is completed. [0003] Automatic revolving doors have high passability and environmental isolation effects. When opening and closing, they can also effectively prevent wind, sand and sound insulation, so that halls and halls remain relatively independent from the ...

AI Technical Summary

Problems solved by technology

However, the existing movable fan anti-collision and fixed ring anti-pinch systems are limited by the structural design ideas, and there are generally phenomena such as the inability to completely avoid collisions with pedestrians and the existence of blind spots in the induction, which affects the performance of the automatic revolving door and causes unnecessary damage. bodily impact or injury
