Automatic rotation door device

Abstract

The invention discloses an automatic rotation door device, and relates to the field of building moving type closing devices. The automatic rotation door device includes a door shaft and a door sash. The front and back of the door sash are provided with liquid bladders. The door shaft is internally provided with a hydraulic cylinder. A piston rod of the hydraulic cylinder is provided with outer threads. Pipelines are arranged between the liquid bladders on the front and back of the door and the hydraulic cylinders. The inner wall of each pipeline is connected with a baffle plate tilting towardsone side of the hydraulic cylinder. The other side of the connecting position of each baffle plate and the corresponding pipeline is provided with a blocking part used for limiting tilting of the baffle plate towards the liquid bladder direction. A flexible assembly is arranged between each baffle plate and each pipeline inner wall. A groove is formed in the door shaft. A rotation block insertedinto the groove is fixedly connected to the door sash. The rotation block is in rotation cooperation with the groove. The rotation block is internally provided with a cylindrical groove. The surface of the cylindrical groove is provided with inner threads matched with the outer threads of the piston rod. According to the automatic rotation door device, the problem that an existing rotation door which does not consume electricity cannot be opened and closed automatically is solved; the automatic rotation door device is mainly used in a family or a public area; through action of own gravity of people, automatic opening and closing of the door sash can be achieved.

Description

technical field [0001] The invention relates to the field of building movable closing devices, in particular to an automatic revolving door device. Background technique [0002] With the development of the automatic door industry, automatic doors are more and more popular among people. Nowadays, many automatic doors are applied to many public places. The existing automatic sliding door system generally recognizes the action of people approaching the door (or some kind of entry authorization) as a door opening signal through the control unit, then opens the door through the drive system, and automatically closes the door after the person leaves. The opening and closing process realizes the control system. [0003] Although the existing automatic doors are neat and elegant, easy to use, and easy to control, they have defects such as high price, many wearing parts, large anti-pinch force, and large power consumption. The rotary curtain type electric door needs to manually pul...
