Three-fold automatic access control device with self-locking function

Abstract

The invention relates to a three-fold automatic access control device with a self-locking function. The three-fold automatic access control device comprises a door body, a traction device, a fixing device, lifting devices and a locking device, wherein the door body is in a linear plane when closed and is in a three-fold stacking state when opened, and the end of one side of the door body is connected with the lifting devices through rotating shafts; the lifting devices are symmetrically arranged on the two sides of the door body, one side of each lifting device is fixed to a wall through a bolt, and the other side of each lifting device is connected with the door body through a rotating shaft; the traction device and the fixing device are installed in a sliding box through bolts and connected with the door body through sliding grooves, and the traction device conducts traction guiding on the door body through a hinge structure; when the door body is closed, the fixing device pops up to fix the door body, and the door body and the fixing device are kept on the same plane; and when the door body is opened, the fixing device returns to the original position. By manufacturing the three-fold automatic access control device with the self-locking function, automatic door opening and closing are achieved, and compared with an existing roller shutter door, the three-fold automatic access control device is small in occupied space and attractive in appearance, and protectiveness is greatly improved.

Description

technical field [0001] The invention relates to an execution mode of an automatic door switch, in particular to a three-fold automatic door device with self-locking. Background technique [0002] With the advancement of science and technology, access control is now tending to realize the development of automation. It no longer requires manual opening and closing of switches, which saves people's travel time, improves safety, and adds a lot of technology to life. [0003] At present, the automatic access control devices mainly use push-pull devices for small ones, and roller shutters for large ones. These two designs take up a lot of space, have an unattractive appearance, and have a low safety factor. With the continuous improvement of public safety and aesthetic requirements To improve, the traditional automatic access control device needs to be upgraded. [0004] The purpose of the present invention is to manufacture a three-fold automatic access control device with self-...
