长城卡扣在安装时，操作者主要通过手感以及声音来判断卡扣安装是否到位，因此在设计时需要注意以下几点：

The Great Wall buckle in the installation, the operator mainly through the feel and sound to determine whether the buckle installation is in place, so the design should pay attention to the following points:

1）、选择合适的变形量。长城卡扣通过紧固件的变形和反弹来实现安装。而太小的变形量容易造成安装不牢固；太大的变形量又容易导致安装困难甚至无法安装，破坏卡扣。

1) select the appropriate amount of deformation. The Great Wall buckle through the fastener deformation and rebound to achieve installation. And too small deformation easily lead to the installation is not solid; too large deformation and easily lead to installation difficulties, and even can not install, damage card buckle.

2）、设计时，注意要使长城卡扣在安装靠位时出现一些比较明显的现象，如声音以及手感上的变化。

2) when designing, attention should be paid to some obvious phenomena such as the sound and the change of hand feel when the Great Wall buckle is installed.

3）、设计时，注意长城卡扣的约束数量，不能出现过约束的情况。约束过多，对零件的加工精度要求较高。在实际装配过程，容易导致安装不到位或不能安装。

3) when designing, pay attention to the number of restrictions on the the Great Wall buckle, and there can be no restrictions. Too many constraints and higher machining accuracy of parts. In the actual assembly process, it is easy to cause the installation not to be in place or can not be installed.
