Automatic arc-shaped door

Abstract

The invention relates to the technical field of an automatic door, in particular to an automatic arc-shaped door. The automatic arc-shaped door comprises a top plate, movable door leaves, fixed door leaves and a protective plate, wherein the protective plate is arranged by surrounding the upper edges of the movable door leaves and the fixed door leaves; and the movable door leaves comprise a driving door leaf and a driven door leaf which is driven to be opened and closed by the driving door leaf. The automatic door is further provided with at least one group of rotating arms; one ends of the rotating arms are articulated in the centre of the top plate, and the other ends of the rotating arms are fixedly connected with the upper edges of the movable door leaves. The automatic door is further provided with a drive device and a transmission mechanism for providing and transmitting power so as to enable the movable door leaves to be opened and closed. As the rotating arms replace an overhead rail and are matched with the drive of a ladder-shaped belt to open and close the movable door leaves, so that great potential safety hazards conventionally caused when the overhead rail which suspends a door body is avoided, gliding noise generated between the suspension rail and a suspension member is avoided, and the service life of the automatic arc-shaped door is prolonged; and besides, the automatic door can be provided with a door control system for entrance authorization and recognition so as to realize a safety control function for preventing the following phenomenon, so that the automatic door can be applied to safety management for the access of important sectors.

Description

technical field [0001] The invention relates to the technical field of automatic doors, in particular to an arc-shaped automatic door. Background technique [0002] At present, automatic doors have been widely used in various fields. An automatic door is a control unit that recognizes the action of a person approaching the door (or a certain entry authorization) as a signal to open the door, and opens the door through the drive system. A system that automatically closes the door and controls the opening and closing process. [0003] The arc-shaped automatic doors in the existing structure generally adopt arc-shaped hanging rails arranged on the fixed guard plate on the top, and a number of hanging parts supported by rollers are arranged on the hanging rails to hang the door body similar to a glass door. Hanging on the hanging rail, the door can be opened and closed by driving the rotation of the glass. However, the arc door with this type of structure not only has a great ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an arc-shaped automatic door to solve the great safety hazards such as easy derailment caused by the arc-shaped doors in the prior art, which generally use hanging rails to hang the glass to rotate and open and close the door. And the sliding noise between the hanging rail and the hanging parts is large, and the problem of limited service life caused by easy wear and tear

[0005] Secondly, another purpose of the present invention is to solve the problem of trailing and unrelated personnel entering and exiting when the personnel entrance and exit management of important departments occurs
