伸缩门特点：

The features of the telescopic door:

1、智能红外线防爬装置：遇人爬门时,系统会马上报警,从而保障工厂内的财产安全。

1, intelligent infrared anti creeping device: when people climb the door, the system will immediately alarm, so as to ensure the safety of the property in the factory.

2、特种型材：在高硬度锌铝合金型材上加上不同几何形状筋骨能大大增强其强度，表面经特殊电泳处理，光泽无限，不易粘尘，不被污染气体腐蚀，决不生锈，保新期长。

2, special profile: adding different shapes and bones on high hardness zinc aluminum alloy section can greatly enhance its strength. The surface is treated by special electrophoresis, the luster is infinite, it is not easy to stick to dust, it will not be corroded by polluting gas, and it will never rust. It will keep the new period long.

3、工程塑料：门体主要塑料件（如管材与管材间的连接，塑料件，门体活动部件等等）采用高质量工程塑料（如PC、PA），韧性高，耐冲击,抗扭曲，耐磨，耐冻，耐晒，不易老化，使用寿命长，免受风雪雷电、日晒雨淋之苦。

3, engineering plastics: main body parts (such as plastic door connecting pipes and pipes between the plastic parts, door body moving parts etc.) with high quality engineering plastics (PC, PA), high toughness, impact resistance, anti distortion, abrasion resistance, frost resistance, light fastness, not easy to aging, long service life. From the snow, lightning, sun and rain.

4、智能红外线探头防碰撞装置：门体在关闭过程中遇人或异物30-50cm可自动返回运行，从而保障车辆及行人的安全。标准结构:门排内空（即前后相临两大弯主管之间的距离，不含主管尺寸）采用伸缩门标准尺寸mm（参照国外技术），保证交叉管坚固，并大大减少运行噪音。

4, intelligent infrared detector anti-collision device: door in the closing process encountered human or foreign matter 30-50cm can automatically return to operation, so as to protect the safety of vehicles and pedestrians. Standard structure: door row space (i.e. between two adjacent large head before and after the distance, without charge size) with retractable door standard size mm (according to foreign technology), cross tube solid, and greatly reduce the operation noise.

5、不锈钢伸缩门，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。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。最新交叉连接设计：交叉管采用特殊工艺冲制而成，并配用超级PA耐磨套，与圆管紧密结合不仅使门排结构更加牢固，而且保证运行更加平滑。

5, stainless steel telescopic door, stainless steel electric expansion door main structure features: stainless steel adopts international standard stainless steel raw materials, after special process pipe bending, welding, stereotyped door body. The door body is never variable and durable. The door body size rod connected to the gate, Dalian bar connection patterns for Gubi plum blossom type, the small connecting rod connected into the link type gate, beautiful appearance, durable. Features of stainless steel telescopic door's movable parts: every part of the expansion joint is made of stainless steel tube, axle, Bush, stainless steel nut and nylon gasket. When assembling, each ring node is filled with advanced lubricant, no noise and self contraction. The electric telescopic door body structure and stainless steel Aluminum Alloy is similar to the use of parallelogram kinematic principle, Aluminum Alloy profiles using standard directly by pressing, and then through the galvanized pipe and cross rod connected into. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is more resistant. Aluminum Alloy telescopic doors, unique craft production door main frame sections connected together by the plastic parts, connection of a screw using stealth design, improve the appearance of the door, profiles and plastic parts are connected by impulse, pressure, drilling process, make the door body firm structure, no solder joints. The latest cross connection design: the cross pipe is punched by special technology, and the super PA wear-resistant sleeve is combined with the round pipe. It not only makes the gate row structure more firm, but also ensures the operation more smooth.

6、伸缩门的特点美化环境、改善企业面貌、提升企业形象;有助于营造文明企业、文明工厂、文明城市气氛;提高安全性、即使深夜遇有破坏或翻越，立刻报警。伸缩门主要用于生活小区，机关学校，企业事业单位、各个工厂，等。

6, the characteristics of retractable doors, beautify the environment, improve the corporate appearance and enhance the corporate image; help create civilized enterprises, civilized factories, civilized city atmosphere, improve safety, and even alarm at night if there is any damage or crossing. Telescopic doors are mainly used in living quarters, institution schools, enterprises and institutions, various factories, and so on.

以上就是电动伸缩门的具体的结构分析，如今这行业发展到今天，技术日益完善，市场日益成熟，社会需求同步壮大，但市场仍然比较分散。更多伸缩门企业亦不断开发新产品，根据客户需求，满足客户更人性化的需求！

The above is the specific structural analysis of the electric telescopic door. Today, with the development of the industry, the technology is improving, the market is becoming more mature, and the social needs are growing simultaneously, but the market is still dispersed. More expansion door enterprises also continue to develop new products, according to customer needs, to meet the customer's more human needs!
