The three-wing revolving door consists of three main components: the fixed frame, the central shaft component, and the rotating component. Each component will be introduced in detail below.
(1) Fixed frame.
The fixed frame consists of an upper support component, a column, upper and lower docks, and a fixed hanging plate. The upper support component is made up of a cap head, multiple beam frames, multiple load-bearing plates, and brackets connected with screws and nuts. The foundation of the fixed frame is between the column and the upper and lower docks. The curved wall glass is also installed between the upper and lower docks and the column. The ceiling is installed on the fixed frame.
(2) Rotating components.
The rotating components consist of a door closer, a display case, a rotating ceiling, and door parts. These rotating components are used for opening and closing the door.
(3) Central axis component.
The central shaft component is the drive system of the automatic revolving door, which is the transmission mechanism that starts and closes the automatic door under the control of the electronic control system. It consists of a gear motor and a transmission mechanism.
Since the design concept of the three-wing automatic revolving door is identical to the mechanical structure of the four-wing automatic revolving door, with similar main structural components, but differing in the number of door components and the shape of the display case, we will not provide a detailed introduction for the three-wing automatic revolving door. Instead, we will focus on discussing the structure of the four-wing automatic revolving door in detail.
