Buckle in general, buckle by positioning parts, fasteners. The function of the positioning piece is to guide the buckle to the installation position smoothly, correctly and quickly. The role of fasteners is: detachable fasteners are usually designed so that when a certain separation force is applied, the buckle will be released and the two connectors will be separated. This kind of buckle is usually used to connect two parts that need to be disassembled frequently. Non-detachable fasteners can be disassembled only when the fasteners are deflected manually. They are mostly used for connecting and fixing parts without disassembling them during use.

Buckle installation matters:

When installing the buckle, the operator mainly determines whether the buckle is installed in place by hand feeling and sound, so the following points need to be paid attention to in the design:

1) Choose the appropriate amount of deformation. Buckles are installed by deforming and rebounding fasteners. And too small deformation is easy to cause unstable installation; Too much deformation is easy to lead to installation difficulties or even unable to install, damage the buckle.

2) During design, pay attention to some obvious phenomena, such as sound and feel changes, when the buckle is installed in the position.

3) In the design, pay attention to the number of constraints on the buckle, can not appear constraints. Too many constraints, high requirements for machining precision of parts. In the actual assembly process, it is easy to cause the installation is not in place or cannot be installed.
