电动伸缩门结构特点
Structural Characteristics of Electric Telescopic Door
不锈钢采用国际标准不锈钢原材料，经过特殊工艺制管进行折弯焊接定型制成门体。门体永不变型坚固耐用。门体用大小连杆连接而成伸缩门，
Stainless steel is made of international standard stainless steel raw materials, which are bended and  by special process to form the door body. The door body will never change into a solid and durable one. The door body is connected by large and small connecting rods to form a telescopic door.
大连杆连接型式为古币梅花式，小连杆连接成菱型式道闸，美观大方，坚固耐用。
Dalian pole connection type is ancient coin plum blossom type, small connecting rod connected into diamond type sluice, beautiful and generous, strong and durable.
不锈钢伸缩门活动部位特点：伸缩门每个活动部位环节均采用不锈钢管，轴，轴瓦，不锈钢螺母，尼龙衬垫组装，组装时每个环节点加注高级润滑油，无噪音伸缩自如。
Features of Stainless Steel Telescopic Door Movable Parts: Stainless steel pipes, axles, bearing bushes, stainless steel nuts, nylon liners are used in each link of the telescopic door. High-grade lubricants are added to each link point during assembly, so that the telescopic door can be flexible without noise.
铝合金电动伸缩门主体结构与不锈钢相似，也是利用平行四边形的运动原理，采用标准的铝合金型材直接用模具压制成型，然后通过镀锌管以及交叉连杆连接而成。与传统的不锈钢电动门相比，材质更优，造型更美观，更加耐腐蚀。
The main structure of the aluminum alloy electric telescopic door is similar to that of stainless steel. It is also made of standard aluminium alloy profile directly pressed by a die and then connected by galvanized tube and cross connecting rod by using the motion principle of parallelogram. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is better.
