一种塑料件卡扣
本技术涉及卡扣
,更具体地说,它涉及一种塑料件卡扣。
技术介绍
子母扣一般包括有子扣和母扣,子扣与母扣扣合在一起实现卡接固定的效果。现有的母扣通常包括有基座以及与基座连接且具有容纳子扣的容纳腔的卡爪,子扣伸进卡爪内撑开卡爪,从而实现卡接固定功能。在公开号为CN205639223U的中国专利公开了一种塑料卡扣,包括子扣和与之配接的母扣,所述子扣包括扣帽以及向下延伸的子扣本体,所述母扣包括基座以及向下延伸的母扣本体,所述母扣本体轴向上设置有收容所述子扣本体的中空部,所述母扣本体的外侧面上设置有至少一个凸起的弹角,所述母扣本体的中空部内侧壁上设置有凸起部,所述子扣本体的外侧壁上设置有与所述凸起部相适配的凹槽,所述子扣本体插进所述母扣本体内,所述凸起部卡设在所述凹槽内。现有技术中类似于上述的塑料卡扣,其将母扣卡入安装孔件内,再将子扣插入母扣,子扣与母扣扣接在一起时,子扣的凸起部卡设在相适配的连接部内,实现子扣本体与母扣本体之间的固定,但是该卡接方式的连接强度较差,在受到外力时,子扣本体容易沿着凹槽的倾斜侧壁脱离凸起部。
技术实现思路
针对现有的技术问题,本技术的目的在于提供一种塑料件卡扣,其具有提高子扣和母扣连接强度的优点。为实现上述目的,本技术提供了如下技术方案:一种塑料件卡扣,包括子扣和母扣,所述母扣包括母扣本体和基座,所述母扣本体的内部呈中空设置,所述母扣本体内壁上设置有凸起部,所述凸起部上设置有多道环母扣本体的轴线周向设置的伸缩缝,所述母扣本体的内壁上设置有环母扣本体轴线周向设置的凸起部,所述子扣插接进母扣内的一端设置有外径与凸起部内径相等且 ...
