Description

拨叉式防盗检查井盖
本实用新型公开了一种拨叉式防盗检查井盖,涉及城市下水道公共设施技术领域。
在市政公共设施中,各种检查井的井盖,因被盗丢失而造成的人身伤害事故屡屡发生,给国家带来经济损失,给人民群众生活安全造成很大影响,虽然有些城市采用在原有井盖安装锁链的方法,但不足是影响井盖的美观,并且锁链很容易被砸断,而盗走井盖。
本实用新型的任务是发明一种拨叉式防盗检查井盖,解决了各种井盖被盗的问题。
为完成上述任务,本实用新型采用如下解决方案:在现有的井盖上设置有拨叉锁紧机构,锁条通过支架安装在井盖边缘,通过其上的销子与拨叉的沟槽滑动配合连接,钥匙轴将拨叉及拨叉支架、井盖铰接为一体,转动钥匙轴带动拨叉转动使锁条平行移动,卡在井口内侧,将井盖固定锁在井口上,防止了井盖被盗。
本实用新型的积极效果在于:利用现有的井盖加装本装置,可将井盖牢固地锁紧在井口上,没有专用钥匙,打不并锁,无法移动井盖,防止了井盖被盗,杜绝了各种检查井因无井盖而发生的伤害事故,锁具结构简单、性能可靠、开启方便,可广泛应用于城市上下水道、通讯电缆、供热燃气等井口封盖。
图1为本实用新型结构原理图。
在附图中,井盖1上分别设有支架4和拨叉架6,拨叉2为长条状,其前半部分开有滑道沟槽,后端通过钥匙轴7铰接在拨叉架6上,锁条5安置在两个支架4中,可在其中左右移动,其上还设有拨叉销钉3,穿在拨叉2的滑道沟槽中,与其构成滑动连接结构。
