电动伸缩门主要由门体、驱动器、控制系统构成。伸缩门的门体采用优质铝合金及普通方管管材制作,采用平行四边形原理铰接,伸缩灵活行程大。伸缩门的驱动器采用特种电机驱动,蜗杆蜗轮减速,并没有手动离合器,停电时可手动启闭,伸缩门的控制系统有控制板,按钮开关,另可根据用户需求配备无线遥控装置。
The electric expansion door is mainly composed of door body, driver and control system. The door body of the expansion door is made of high-quality aluminum alloy and common square pipe material. It is hinged on the principle of parallelogram, with large flexible expansion stroke. The driver of the expansion door is driven by a special motor, the worm and worm gear decelerate, there is no manual clutch, and it can be opened and closed manually in case of power failure. The control system of the expansion door has a control board, a button switch, and a wireless remote control device according to the user's requirements.
不锈钢电动伸缩门主体结构特点：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。
Main structure features of stainless steel electric expansion door: the stainless steel adopts international standard stainless steel raw materials, and the door body is made by bending and welding after special process pipe making. The door body is durable and durable. The door body is connected with large and small connecting rods to form an expansion door. The connecting type of Dalian rod is old coin plum blossom type, and the connecting type of small connecting rod is diamond type road gate, which is beautiful, generous, solid 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，无噪音伸自缩自如。
Features of movable parts of stainless steel expansion door: each movable part of the expansion door is assembled with stainless steel pipe, shaft, bearing bush, stainless steel nut and nylon pad. During assembly, each ring node is filled with high-grade lubricating oil, which can stretch and shrink freely without noise.
