Uncoupling is a broken roller shutter shaft tube. If the roller of the shutter door is broken, it can only be replaced with a new one. At the same time, it is necessary to check whether the bolts of the roller tube of the shutter door are loose. After purchase, install the shaft tube in place first, and tighten the bolts at the same time, so as to avoid looseness.

卷帘门脱轴还可能与线路有关系，比如控制线路中有一些线没有接好，或者被拉扯断了，要排查一下电路的问题，有一个电机引线，如果与继电器的插头因为震动产生脱落也容易造成故障，所以需要把电线重新维修一下。

Roller shutter off-axis may also be related to the circuit, for example, some wires in the control circuit are not connected well, or are pulled off. First of all, check the circuit problem. There is a motor lead, if it falls off with the relay plug due to vibration, it is easy to cause fault, so the wire needs to be repaired again.

卷帘门上下的推拉需要在导轨里实现，如果卷帘门出现脱轨就会出现卡壳，容易出现上去下不来或者是能下不能上的情况，卷帘门松动就会出现门自动滑下来，容易造成他人伤害。

The up and down push and pull of the rolling shutter door needs to be realized in the guide rail. If the rolling shutter door derails, it will get stuck. It is easy to get up and down, or it can't get down. If the rolling shutter door is loose, it will slide down automatically, which is easy to cause injury to others.

注意事项：

matters needing attention:

1、在安装过程中一定要注意线路的完整性，规范化操作和安装卷帘门。

1. In the installation process, we must pay attention to the integrity of the line, standardized operation and installation of rolling shutter door.

2、我们在使用卷帘门时应注意卷帘门轨道及吊轮不能上油，否则吊架上的滚轮有滑动现象，使门发生碰撞。

2. When we use the rolling shutter door, we should pay attention to that the track and hanging wheel of the rolling shutter door should not be oiled, otherwise the roller on the hanger will slide, causing the door to collide.
