Structure capable of realizing constant interval between primary door and secondary door of one-way door with flush door leaf

Abstract

The invention discloses a structure capable of realizing a constant interval between a primary door and a secondary door of a one-way door with a flush door leaf, comprising the primary door and the secondary door which are matched with each other, wherein the primary door consists of three doors that are fixed on a main shaft, the secondary door is arranged on a movement mechanism, and moves back and forth in a rectilinear direction, the moving direction of the secondary door is towards an axis of the main shaft, the back-and-forth movement of the secondary door ensures that the secondary door is alternatively located in each included angle of the doors of the primary door when the primary door rotates in a constant velocity, and a triangular fixing bracket of a triangular structure is arranged at an edge of the secondary door. According to the invention, as the triangular fixing bracket of the triangular structure ensures that a constant interval between the primary door and the secondary door is realized in the rotation process of the primary door, influence on safe and normal operation of the one-way door due to the problem of non-constant intervals between the primary door and the secondary door when a primary door and a secondary door are in different movement states in the prior art is avoided.

Description

technical field [0001] The invention relates to a structure of constant distance between the main door and the auxiliary door of a one-way door with plane leaves. Background technique [0002] The Chinese Patent Application No. 201310065625.1, which was previously applied by the applicant, "a one-way door with a flat door leaf", proposes a one-way door with a flat door leaf that avoids pedestrians walking in the opposite direction, is not ventilated, has a compact structure, is reasonable, and operates smoothly. In this file, during the rotation of the main door, there is always a main door in contact with the auxiliary door and a small gap is maintained, and pedestrians can only walk in one direction. However, the applicant found in actual use that: the edge of the auxiliary door is designed as a curved auxiliary door structure, and during the relative movement of the main door and the auxiliary door, the distance between the two is not constant, that is : Sometimes the di...

Problems solved by technology

However, the applicant found in the actual use process that the edge of the auxiliary door is designed as a curved auxiliary door structure. During the relative movement of the main door and the auxiliary door, the distance between the two is not constant, that is, : Sometimes the distance between the main door and the auxiliary door is too large, and sometimes the distance is too small

This does not meet the requirements of actual use, because if the distance is too large, items may be passed inside and outside the door, and if the distance is too small, it may affect the operation of the equipment
