扣位也称卡扣,是塑胶件连接固定的常用结构,在强度要求不高的情况下可以用于代替螺丝固定.扣位设计在于“扣”,需要结合紧密,保证测试强度,达到安装目的即可.卡扣常做在装饰件固定,面底壳组装,屏固定,按键限位,盖体扣合,方向球等结构处.

Buckles, also known as buckles, are commonly used structures for connecting and fixing plastic parts, which can be used to replace screw fixing under low strength requirements. Buckles are designed to be "buckles", which need to be tightly combined to ensure test strength and achieve installation purposes. Buckles are often used for fixing decorative parts, assembling face and bottom shells, screen fixing, keyboard limiting, and cover fastening. Structures such as directional spheres.

卡扣：分公扣,母扣；公扣为凸,母扣为凹。

Buckle: Buckle in centimeters, Buckle in buses; Buckle in buses is convex, Buckle in buses is concave.

卡扣原理:

Buckle principle:

扣合前:有导向斜角引导扣合方向,公母定送水  铜鼎铜钟 淤泥固化设备 化粪池钢模具 拱形骨架模具 保定代理记账 保定道闸
扣均做导入角,一般取60°,45°.

Before buckling: there is a guide angle to guide the direction of buckling, both male and female buckles do the lead-in angle, generally take 60 degrees, 45 degrees.

扣合中:公扣弹性臂变形压入,弹性臂要保证变形,强度要足够,一般变形量≧扣合量.

In buckling, the elastic arm of the public buckle should be deformed and pressed in. The elastic arm should be deformed and its strength should be sufficient. Generally, the amount of deformation is greater than or equal to the amount of buckling.

扣合后:公扣凸与母扣凹贴合,分离方向不易取出,要求扣合面或扣合角小于导向斜角.

After buckling: the buckle convex and the busbar concave fit together, the separation direction is not easy to take out, and the buckling surface or the buckling angle is required to be less than the guiding angle.
