Abstract

本实用新型涉及一种定时器机芯的外壳的卡位装置。所述连接装置采用如下构造:在侧壁顶沿上设有凸键,凸键的宽度上宽下窄,与该凸键对应的盖板上设有大小匹配的通孔。盖板的固定非常简便,只需将盖板的通孔与凸键插接,随后通过外力使得凸键扭转一定角度,就可以将盖板固定。

Description

一种定时器的外壳卡位装置
                    技术领域
本实用新型涉及一种定时器机芯的外壳的卡位装置。
                    背景技术
定时器机芯的外壳一般呈方体的盒状,方体的侧壁顶沿上设有与盖板固定连接的连接装置,该连接结构一般采用螺钉、销等方式。但上述连接构造在生产成本和加工工艺上都不是很理想,尤其需要拆开定时器外壳盖板时不是很方便。
                    发明内容
本实用新型的目的在于提供一种工艺简单,拆装方便的定时器的外壳卡位装置。为实现上述发明目的,本实用新型采用了如下技术方案:一种定时器的外壳卡位装置,其外壳呈方体的盒状,方体的侧壁顶沿上设有与盖板固定连接的连接装置,其特点是所述连接装置采用如下构造:在侧壁顶沿上设有凸键,凸键的宽度上宽下窄,与该凸键对应的盖板上设有大小匹配的通孔。
所述凸键呈“T”字形,该“T”字形凸键的横条与通孔的大小相匹配,该“T”字形凸键的竖条的高度与盖板的厚度相当。
由于采用了上述技术方案,盖板的固定非常简便,只需将盖板的通孔与凸键插接,随后通过外力使得凸键扭转一定角度,就可以将盖板固定。
               附图说明
图1本实用新型结构示意图
               具体实施方式
如图1所示:定时器的外壳卡位装置,其外壳1呈方体的盒状,方体的侧壁2顶沿上设有与盖板3固定连接的连接装置,所述连接装置采用如下构造:在侧壁顶沿上设有凸键4,所述凸键呈“T”字形,与该凸键对应的盖板上设有大小匹配的通孔5。该“T”字形凸键的横条6与通孔的大小相匹配,该“T”字形凸键的竖条7的高度与盖板的厚度相当。

Claims (2)
