Description

带暗锁的井盖
本实用新型涉及一种路面井盖,属于一种带锁的井盖。
路面井盖被人搬走造成事故,是常见的事。为此,有不少将井盖固定于地面的技术方案申请专利,有的埋入连接件作永久固定;有的设置闩锁,配备专用工具。这些装置,大都存在不方便,或者构造复杂,易堵塞失灵等缺点,尤其是一项发明的批量生产,常常只有一把特制工具,打开所有的井盖,防盗的效果就有限了。
本实用新型的目的,是要提供一种构造简单,可靠性强,可对不同用户配备不同锁具的暗锁井盖。
实用新型是这样实现的:在井盖下设有支架,支架内穿插有闩,闩一端有钩头置于锁片内,锁片一面有与开启工具相吻合的凸凹口。
这种暗锁井盖,表面上与普通井盖一样,盖下的闩插入底座止口下,起着锁定作用,需要有专门的带钥匙提手才能开启井盖。钥匙和锁片的吻合凸凹口,可以任意变动,增强了不同用户的保密效果。
下面结合附图介绍本实用新型的构造和作用。
图1为实用新型主视图;
图2为实用新型俯视图;
图3为实用新型右视图。
参照附图,井盖[1]下面通过支架[2]装有闩[5]。在井盖上的孔[3]旁,下面固定有锁片[4],锁片靠孔[3]一面加工有凸凹口[8],与提手下面的钥匙相吻合,从井盖孔[3]插入的提手[7]下面的钥匙片转动,通过锁片的凸凹口可拨动闩钩,使闩[5]退出或插入底座[6],实现井盖的锁定作用。
