电动伸缩门结构特点
Structure characteristics of electric expansion 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 adopts international standard stainless steel raw material. After special process pipe bending, welding is made into door body. The door body is never variable and durable. The door body is connected to a telescopic door with a connecting rod and a connecting rod.
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 bar connection patterns for Gubi plum blossom type, the small connecting rod connected into the link type gate, beautiful appearance, 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。
The characteristics of stainless steel telescopic door moving part: each part of the telescopic door is composed of stainless steel tube, shaft, axle bush, stainless steel nut, nylon liner.
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 electrotelescopic door is similar to the stainless steel. It is also a parallel quadrilateral movement principle. The standard aluminum alloy profile is used to form the mould directly with the die, and then it is connected by the galvanized pipe and the cross connecting rod. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is more.
