伸缩门特点：
Features of retractable 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 climbing device: when people climb the door, the system will immediately alarm, so as to protect the property safety 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: the strength of high hardness zinc aluminum alloy profile can be greatly enhanced by adding different geometric shapes of ribs. The surface is treated by special electrophoresis, which has unlimited luster, is not easy to stick to dust, is not corroded by polluted gas, and is never rusty. The new period is 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: the main plastic parts of the door body (such as the connection between pipes, plastic parts, movable parts of the door body, etc.) are made of high-quality engineering plastics (such as PC, PA), with high toughness, impact resistance, torsion resistance, wear resistance, frost resistance, sun resistance, aging resistance, long service life, free from wind, 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 probe anti-collision device: the door can automatically return to run when it meets people or foreign matters 30-50cm in the process of closing, so as to ensure the safety of vehicles and pedestrians. Standard structure: the inner space of the door row (i.e. the distance between the two bending main pipes at the front and back, excluding the main pipe size) adopts the standard size mm of the telescopic door (referring to foreign technology), which ensures the firmness of the cross pipe and greatly reduces 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。假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵
5. Stainless steel telescopic door, stainless steel electric telescopic door main structure features: stainless steel using international standard stainless steel raw materials, through special process pipe bending welding shaping made of door body. The door body will never change, and it is durable. The door body is connected by big and small connecting rods to form a telescopic door. The connecting type of Dalian connecting rod is ancient coin plum blossom type, and the connecting type of small connecting rod is rhombic type. It is beautiful, elegant, firm and durable. Features of stainless steel telescopic door: each part of the telescopic door is assembled with stainless steel pipe, shaft, bearing bush, stainless steel nut and nylon gasket. Each ring node is filled with high-grade lubricating oil during assembly, which can stretch and shrink freely without noise. The main structure of aluminum alloy electric telescopic door is similar to that of stainless steel. It is also made of parallelogram movement principle, using standard aluminum alloy profiles, directly pressed by mold, and then connected by galvanized pipe and 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 better. 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 at the connection position adopts a hidden design to improve the appearance of the door body. The connection between the profile and plastic parts adopts punching, pressing, drilling and other processes, so that the door body structure is firm and there is no welding point. The latest cross connection design: the cross pipe is made by special technology and equipped with super PA wear-resistant sleeve. It is closely combined with the round pipe, which not only makes the gate structure more firm, but also ensures smooth operation.
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 door beautify the environment, improve the appearance of the enterprise, enhance the image of the enterprise; It helps to create the atmosphere of civilized enterprise, civilized factory and civilized city; Improve the safety, even if there is damage or crossing at night, immediately report to the police. Retractable door is mainly used in living quarters, institutions, schools, enterprises, factories, etc.
