Problems solved by technology

[0003] In order to solve the large space required for the installation and use of the existing revolving door rails, when the door rails are opened at a small angle, it will affect the passage of people, and when the door rails are automatically closed, there will be a rapid closing impact due to the large door rail angle.

Embodiment Construction

[0015] An embodiment of the present invention will be described below with reference to the accompanying drawings.

[0016] exist figure 1 Among them, a rotating gate (6) and a sliding gate (16) are set on the rotating shaft (4). When the door is opened, the rotating gate (6) drives the turning mechanism gear (1) through the intermediate gear (2) and the traction gear ( 8) Engage, drive the traction rope (13) and compress the spring (14) to drive the sliding gate (16) to shrink, to realize the synchronization of the opening and rotation of the gate and the contraction of the sliding gate, so as to increase the opening of the gate and reduce the time required for the opening of the gate. space. When the sliding gate locking mechanism (15) is used to realize the locking of the retractable gate when the gate stops rotating.

[0017] In Fig. 3, the sliding gate locking mechanism expands and contracts through the combination or separation of the inner cone surface of the limiting...

Abstract

This invention relates to single direction contract door to improve it utility and install environment, wherein, the Single door can be fixed with one layer of board to be one turning contract door. The single direction contract door comprises one rotation door on shaft and slide door, wherein, the door is opened to drive rotation structure gear through middle gear and drive gear and the drive rope compressed spring drives slide door to realize door rotation and slide door contract at same time to add door open degree and decreases door open space.

Description

technical field [0001] The invention belongs to a one-way revolving door structure. Background technique [0002] At present, there are two kinds of common one-way revolving doors. One is the three-pronged revolving door controlled by the ratchet wheel of the horizontal shaft. , the passing speed is low, and the installation space is required to be large, and it is mostly used at the entrance of stations, parks, etc.; a gate-type one-way opening revolving door with a vertical shaft, which adopts one-way opening and automatic closing, so that the gate The direction of turning is consistent with the flow of people to limit the one-way flow of people. However, since this kind of door is a fixed-length door rail, the length of the door rail determines its opening radius, resulting in a large installation space and use space, which affects occasions with small spaces and movement. use in the occasion. The rotation angle of this kind of door rail does not correspond to the openi...
