电动伸缩门采用剩余四边形运动原理，采用标准铝合金型材准铝合金型材，然后通过镀锌管和交叉连杆连接。与传统的不锈钢电动门相比材料更好，外观更美观，耐腐蚀性更好。自动伸缩门可电动控制，可伸缩，可大可小，可根据需要调整门体开闭空间的大小。
The electric telescopic door adopts the principle of residual
quadrilateral movement, adopts standard aluminum alloy profile and quasi
aluminum alloy profile, and then is connected with cross connecting rod
through galvanized pipe. Compared with the traditional stainless steel
electric door, the material is better, the appearance is more beautiful
and the corrosion resistance is better. The automatic telescopic door
can be electrically controlled, retractable, large or small, and the
opening and closing space of the door body can be adjusted according to
needs.
