Abstract

一种地锁防尘罩，套管侧壁上至少设置两个导向筋；护盖板中心开有椭圆形通孔；滑行块为内凹的圆柱形，其表面为椭圆形凸起，椭圆形凸起两侧为台阶侧壁；台阶侧壁上设置有与导向筋相对应的开口；一弹簧置于套管内，顶端在顶滑行块的内凹背面；滑行块上的开口与套管侧壁上的导向筋滑动连接；护盖板上的椭圆形通孔与滑行块上的椭圆形凸起配合安装，护盖板座落在滑行块上的台阶侧壁上。本实用新型的护盖板及滑行块均采用了椭圆形结构，即将原有的圆形结构改变为椭圆形结构，这样在使用时，即使锁舌发生位移，也不会插不进套管内；同时，护盖板起到了防止灰尘、杂物落入的作用。本实用新型结构可以延长门锁的使用寿命。

Description

地锁防尘罩
技术领域
本实用新型是应用于地锁用的防尘罩。
现有技术
现有应用于落地门的地锁罩，结构为一内径截面为圆形的套官，安装在地面上。使用时，门上的锁舌可以进入到圆形的套筒内，达到锁门的目的。这种地锁罩结构的缺点是，由于门的本身自重，长期使用难免会造成顶端往下垂。而门自重下垂，可使锁体同门一起移位，造成锁舌的中心位置偏离地锁罩套筒的中心，因而锁舌不能进入到防尘罩内，不能达到锁门的目的，而且影响门锁的使用寿命；而且地锁罩位于地面，长期开口，也会落入灰尘、杂物造成堵塞，影响使用效果。 
 发明内容
本实用新型为克服上述已有技术存在的缺点，提供一种改进的地锁防尘罩。
一种地锁防尘罩，其特征在于，套管侧壁上至少设置两个导向筋；护盖板中心开有椭圆形通孔；滑行块为内凹的圆柱形，其表面为椭圆形凸起，椭圆形凸起两侧为台阶侧壁；台阶侧壁上设置有与导向筋相对应的开口；一弹簧置于套管内，顶端在顶滑行块的内凹背面；滑行块上的开口与套管侧壁上的导向筋滑动连接；护盖板上的椭圆形通孔与滑行块上的椭圆形凸起配合安装，护盖板座落在滑行块上的台阶侧壁上。
本实用新型的护盖板及滑行块均采用了椭圆形结构，即将原有的圆形结构改变为椭圆形结构，这样在使用时，即使锁舌发生位移，也不会插不进套管内；同时，护盖板起到了防止灰尘、杂物落入的作用。本实用新型结构可以延长门锁的使用寿命。
为了使滑行块不转动方向，本实用新型在套管侧壁上设置有导向筋进行导向；本实用新型在使用时，见附图6，即锁门时，滑行块顺着导向筋开始定向下移，锁舌随即进入套管内；开锁时，见附图5，锁舌复位，该滑行块受到弹簧伸展外力进行复位。本实用新型采用弹簧伸缩原理，驱使滑动块进行开启和复位，使用灵活，定位准确。
附图说明
附图1是本实用新型套管结构示意图。
附图2是本实用新型滑行块结构示意图。
附图3是本实用新型滑行块剖面结构示意图。
附图4是本实用新型护盖板结构示意图。
附图5是图4的剖面结构示意图。
附图6是本实用新型未工作状态结构示意图。
附图7是本实用新型工作状态结构示意图。
1护盖板、11椭圆形通孔、2套筒、21导向筋、3弹簧、4锁舌、5滑行块、51椭圆形凸起、52开口、53台阶侧壁。
具体实施方式
一种地锁防尘罩，套管2侧壁上对称设置两个导向筋21；所述导向筋有可以根据需要设置多个。护盖板1中心开有椭圆形通孔11；
滑行块5为内凹的圆柱形，其表面为椭圆形凸起51，椭圆形凸起两侧为台阶侧壁53；台阶侧壁上设置有与导向筋21相对应的开口52；一弹簧3置于套管内，顶端在顶滑行块的内凹背面；滑行块上的开口与套管2侧壁上的导向筋滑动连接；护盖板上的椭圆形通孔与滑行块上的椭圆形凸起配合安装，护盖板座落在滑行块上的台阶侧壁上。
