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.

卷簾門脫軸還可能與線路有關系，比如控制線路中有一些線沒有接好，或者被拉扯斷了，要排查一下電路的問題，有一個電機引線，如果與繼電器的插頭因為震動產生脫落也容易造成故障，所以需要把電線重新維修一下。

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.

卷簾門上下的推拉需要在導軌里實現，如果卷簾門出現脫軌就會出現卡殼，容易出現上去下不來或者是能下不能上的情況，卷簾門松動就會出現門自動滑下來，容易造成他人傷害。

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.

注意事項：

matters needing attention:

1、在安裝過程中一定要注意線路的完整性，規范化操作和安裝卷簾門。

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

2、我們在使用卷簾門時應注意卷簾門軌道及吊輪不能上油，否則吊架上的滾輪有滑動現象，使門發生碰撞。

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.
