Main structure features of stainless steel telescopic door and stainless steel 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，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。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，无噪音伸自缩自如。 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。铝合金伸缩门,独特工艺制作门体主框架型材由塑料件连接而成，连接位的螺丝固定采用隐型设计，提高门体的外观性，型材与塑料件的连接则采用冲、压、钻等工艺，使门体结构牢固, 绝无焊点。
Stainless steel is made of international standard stainless steel raw materials. The door body is made by bending, welding and shaping the pipe through special process. The door body will never change, firm and durable. The door body is connected by large and small connecting rods to form a telescopic door. The connecting type of Dalian rod is ancient coin plum blossom type, and the small connecting rod is connected into a rhombic type gate, which is beautiful, strong and durable. Features of moving parts of stainless steel telescopic door: each moving part of the telescopic door is assembled with stainless steel pipe, shaft, bearing bush, stainless steel nut and nylon gasket. During assembly, each ring node is filled with high-grade lubricating oil, without noise, and can extend and retract freely. The main structure of aluminum alloy electric telescopic door is similar to that of stainless steel. It is also formed by using the motion principle of parallelogram, using standard aluminum alloy profiles, directly pressing and forming with molds, and then connecting through galvanized pipes and cross connecting rods. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful and corrosion-resistant. The aluminum alloy telescopic door is made by a unique process. The main frame profile of the door body is connected by plastic parts. The screw fixation of the connection position adopts concealed design to improve the appearance of the door body. The connection between the profile and the plastic parts adopts punching, pressing, drilling and other processes to make the door body structure firm without welding points.
