Problems solved by technology

Due to the adoption of the above scheme, the automatic retractable door can not only stand in front of the gate of the courtyard like a screen, but also can expand or contract section by section when opening and closing the door, so that the door body can move lightly; The disadvantage is that the door has poor ventilation performance, and the processing is more troublesome and the cost is higher; there are also some models that weld pipe fittings between the frames to form a certain shape. In this way, the distance between the frames is relatively large, and the processing is also troublesome and complicated; The way is fixed connection, it is not easy to replace the door when it is damaged, and the shape of the door body is fixed, which does not meet people's various aesthetic requirements
The disadvantage of the fixed connection of the main frame in this way is that the processing of the entire telescopic door is complicated and troublesome, and the volume is large, which increases the transportation cost, and it is inconvenient to maintain and cannot be replaced when it is damaged.
[0003] And the display screen of the retractable door of prior art, because the display screen is located in the wind and rain place, the environment is relatively harsh, and often is in motion state, so it is necessary to protect the installation of the display screen, and the existing installation The display screen on the door frame is generally installed directly on it, the structure is not firm, and at the same time, rainwater easily flows into it during use, thus causing damage
In addition, the existing machine head assembly that drives the telescopic door movement is generally sealed in the machine head box. The machine head box is an integral structure, and the box is provided with a cover, which is fixed by screws or other fasteners. During maintenance, the fasteners on the box cover must be removed before the internal parts can be maintained, which is difficult to install and maintain. However, the driving wheels or walking wheels at the lower part of the machine head box and telescopic door frame are directly installed on the wheel shaft. On the other hand, since the telescopic door often needs to be opened or closed, the wheel body is prone to loosening

Abstract

The invention discloses a new expansion door, comprising expansion door frame, door piece set in the frame and head component driving the expansion door move. Driven walking wheels or walking wheels are set at the lower end of head component and expansion door frame. The characteristic technical project is that the door piece set in the frame comprises up-down transversal connection bars; middles of up-down transversal connection bars are connected together through vertical rotation shaft; two ends of up-down transversal connection bar are connected with two-sides vertical connection bars respectively; shear four-link door piece structure is constituted by up-down transversal connection bars and vertical connection bars at two ends; stainless steel net is set in the middle of door piece; sliding strips are set on surfaces of up-down frames of expansion door frame; and ends of vertical connection bars are set on sliding strips and are connected with it actively. By inverter motor speed regulation of expansion door is realized. The display is X-shape. It is provided with convenient and quick assembly and disassembly, convenient control, low cost and beautiful figuration.

Description

technical field [0001] The invention relates to the technical field of telescopic doors, in particular to the technical improvement of telescopic doors. Background technique [0002] The telescopic door of prior art generally comprises telescopic door frame body, the door piece that is arranged in the frame body, the machine head assembly that drives telescopic door movement, and the machine head assembly and telescopic door frame body bottom are all provided with driving wheel or road wheel, and door piece The middle is generally a diagonally supported multi-link structure, and the gap between the door pieces is relatively large, and some are screen-type. The frame is generally welded and fixedly connected.
