电动伸缩棚在日常生活中应用广泛，但是市面上的品种繁杂，质量不一。很多人往往不知道该如何选择。下面分享的几点，可以在一定程度上帮助我们正确选择推拉棚。

Electric telescopic sheds are widely used in daily life, but there are a variety of varieties and varying quality on the market. Many people often don't know how to choose. The following points shared can help us to choose the right sliding shed to a certain extent.

一、从伸缩棚顶部的架子判断。

1、 Judging from the frame at the top of the telescopic shed.

棚架需要合理的距离来满足斜拉筋的数量，质量差的伸缩棚斜拉筋会少，距离太长。偷工减料的结果是结构承载力严重不足，结构简单变形，使用寿命严重降低。抵御不了风，随时有倒塌的危险。

The top shelf requires a reasonable distance to meet the quantity of diagonal braces. Poor quality expansion sheds will have fewer diagonal braces and a too long distance. The result of cutting corners and materials is a serious lack of structural bearing capacity, simple deformation of the structure, and a serious reduction in service life. Unable to withstand the wind, there is a risk of collapse at any time.

二、弹力架长度合理。

2、 The length of the elastic frame is reasonable.

弹性框架长度影响柱的稳定性，从而影响整体稳定性。

The length of the elastic frame affects the stability of the column, thereby affecting the overall stability.

三、螺栓的材料

3、 Material of bolts

螺栓是连接立柱和顶架的铰链，一般单独使用加厚管。质量差的是用边角料。螺栓是车架受力的关键部位，材质尤为重要，直接影响牢固程度。边角料的使用导致危险寿命短。

The bolt is a hinge that connects the column and the top frame, usually using thickened pipes separately. Poor quality is achieved by using leftover materials. The bolt is a key part of the frame under stress, and the material is particularly important, which directly affects the firmness. The use of scraps leads to a short hazardous lifespan.

四、布料的材料。

4、 The material of the fabric.

电动伸缩棚选用PVC网布，抗拉强度强，使用寿命约5-10年。而差的伸缩棚是用普通廉价油补充的，年限的约束大概短1-2年。

The electric telescopic shed is made of high-quality PVC mesh fabric with strong tensile strength and a service life of about 5-10 years. The poor telescopic shed is supplemented with ordinary cheap oil, and the lifespan constraint is about 1-2 years short.

五、制造技术

5、 Manufacturing Technology

制造时通常先制造模具，零件长度普通，冲压方向普通，开口正常，受力均匀，长度普通，无扭转。质量差异是:长度不符和打孔错误。冲压误差，简单断裂，长度误差，扭转。顶篷活动需要统一驱动所有附件。如果配件不对称，就容易产生各种扭转，不容易拉动，简直损坏配件，降低寿命。

When manufacturing, molds are usually made first. The length of the parts is ordinary, the stamping direction is ordinary, the opening is normal, the force is uniform, the length is ordinary, and there is no torsion. The quality difference is: inconsistent length and incorrect punching. Stamping error, simple fracture, length error, torsion. The roof activity requires a unified drive for all accessories. If the accessories are asymmetrical, it is easy to produce various twists, not easy to pull, and it is simply damaging the accessories, reducing their lifespan.
