所述滑块 25包括由所述主板 23的底面向下延伸的凸块 31及由 所述主板 23的相应侧边向外凸伸且卡于所述卡盖 14上的卡块 32。 所述凸块 31与所述卡块 32的连接处进行倒角处理而形成导引面 33。 所述卡盖 14第一端 15的顶部开设有供所述挡块 24滑动其内的第一 滑槽 34及供所述滑块 25滑动其内的第二滑槽 35。 所述第二滑槽 35 包括容置所述凸块 31的凸块槽 36及容置所述卡块 32的卡块槽 37。 所述卡块槽 36与所述卡盖 14的顶面之间形成有阻挡所述卡块 32脱 离所述卡块槽 36的阻挡部 38。 所述导引面 33引导所述卡块 32滑过 所述阻挡部 38而进入所述卡块槽 37内。
所述卡盖 14的第一端 18开设有供所述锁扣 21的主板 23嵌入的 嵌槽 41。 所述容置槽 17于所述卡盖 14内的深度大于所述嵌槽 41于 卡盖 14内的深度。所述嵌槽 41于所述卡盖 14的第一端 18设置有圆 弧面 42。 所述卡勾 22的底端缘设置有倒角面 43。 所述卡勾 22的倒 角面 43在朝向所述壳体 12按压所述锁扣 21时滑过所述圆弧面 42并 使所述卡勾 22在所述弹性金属丝 20的弹力作用下卡于所述卡槽 26 内。
组装时， 先将所述弹性金属丝 20平放于所述卡盖 14的容置槽 17内， 使弹性金属丝 20受限于所述容置槽 17内。 然后， 将锁扣 21 向下卡于所述卡盖 14上， 此时， 弹性金属丝 20夹置于所述卡盖 14 与所述锁扣 21之间， 所述锁扣 21的挡块 24滑动于第一滑槽 34内， 所述锁扣 21的滑块 25滑动且卡于所述第二滑槽 35内。 然后， 所述 卡盖 14的第二端 16枢接于所述壳体 12上。 在使用过程中， 朝向所 述壳体 12按压所述卡盖 14， 所述卡勾 22的倒角面 43在朝向所述壳 体 12按压所述卡盖 14时滑过所述圆弧面 42， 锁扣 21的挡块 24与 滑块 25相对于所述卡盖 14朝外滑动， 此时， 所述挡块 24抵压弹性 金属丝 20的相应抵持部 28并使弹性金属丝 20处于压缩状态。 在所 述弹性金属丝 20的弹力作用下， 所述卡勾 22卡于所述卡槽 26内。 此时， 所述锁扣 21装置处于锁紧状态。 当需要开启所述锁扣 21装置 时， 只需要朝外推动所述锁扣 21， 将卡勾 22由所述卡槽 26内脱离。 无论是锁扣装置在锁紧过程中还是开启过程中， 所述卡盖 14的第二 端 16的转轴 44在轴孔 45内转动。 因此， 本发明提供的锁扣 21结构 使用方便， 工艺简单。
利用弹性金属丝 20为锁扣 21提供弹力， 工艺简单， 性能可靠。 弹性金属丝 20体积小， 占用空间小， 组装时先将弹性金属丝 20放进 容置槽 17里， 可避免弹性金属丝 20在装配时乱蹦及丢失。
以上所述之具体实施方式为本发明的较佳实施方式，并非以此限定本 发明的具体实施范围， 本发明的范围包括并不限于本具体实施方式。 凡依照本发明之形状、结构所作的等效变化均包含本发明的保护范围 内。
