Description

防水防尘机械锁
本实用新型涉及一种机械锁,特别是一种带防水防尘装置的挂锁。
锁在社会活动、生产活动和人民生活中被普遍使用,一般大门、库房、居民户门、箱子都使用挂锁,在门与门框间或两扇门间安有扣吊或门鼻子,将锁的U形环穿入扣吊或门鼻子的圆孔,按下U形环,使U形环与锁体闭合,门就锁好了,挂锁具有安装方便,价格低等优点,但在使用过程中,由于其挂在室外,常被雨水、灰尘浸蚀,有时造成生锈,难于打开,给人们带来很大不便。
本实用新型的目的是提供一种防水防尘机械锁,它带有防水防尘装置,可避免锁生锈、浸蚀,造成锁难于打开的情况发生,使用更安全。
本实用新型的目的是这样实现的,它包括锁体、U形环、锁芯,其在U形环与锁体配合处设有密封圈和密封盖,锁体与U形环配合的圆孔边缘,设有凸起圆环,密封圈和密封盖穿入U形环,与凸起圆环密封,该U形圆环开启端为阶梯形,阶梯处设有小檐,小檐与锁体圆孔所设凸起圆环密封,起到防水防尘的作用。
本实用新型解决了挂锁使用过程中易生锈积尘使难于打开的问题,由于挂锁使用于户外常被雨淋,灰尘浸蚀,对于库房大锁,有的不常打开,就更易生锈,难于开启。在我国南方气候潮湿、雨水量大,问题也很普遍。本实用新型解决了以上不足,提高了挂锁的适用性。
图1是本实用新型锁住时的剖面图。
图2是本实用新型打开时的剖面图。
下面结合附图及实施例详细说明本实用新型。
如图所示,本实施例包括锁体1、U形环2、锁芯3,它还包括密封圈4,密封盖5,在锁体的圆孔上设有凸起圆环101,U型环的开启端设有小檐201。
锁在锁住状态,凸起圆环101与密封圈4和密封盖5密封,小檐201与凸起圆环101密封。锁在使用中一般靠自重作用,锁体1在下,U型环2在上,以上密封装置将U形环与锁体相接圆孔密封,则雨水,灰尘不能进入锁的内部,故起到防水防尘的作用。
