自动伸缩门逐渐成为一些地方的主要选择。
Automatic telescopic door has gradually become the main choice in some places.
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，材料更好流水槽钢模具 不锈钢铸件 扭王字块模具 井盖钢模具 标志桩模具 调匝式消弧线圈 风冷控制柜 烤漆龙骨外观更美观，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.
