Abstract

按钮式三保险门锁,避免了现有保险门锁要用钥匙才能进行保险的麻烦,锁门后只要随手将保险钮按下即可保险。是由保险钮1、轴用弹性挡圈2、挡板3、弹簧4,开锁凸块5,开保险凸块6,卡子7组成。
本实用新型可在一般碰锁上加装几个非常简单的零件制成,投资少。制造工艺简单,见效快。

Description

目前我国大量使用的门锁是活舌门锁,俗称碰锁。它具有关门即锁的优点,但由于保险的方式都需要将钥匙插入锁眼,反转360°或旋出方舌,这就带来了使用的不便。失去了碰锁“带门即锁”的优点。而且人们在出门或上班时的时间都很紧张,一般都没有习惯再掏钥匙来保险,这样保险锁有时也就失去了保险的意义。
本实用新型改变了原来的保险方法,在锁门后,只要随手将保险钮1按下,此时卡子7卡死挡板3,从而锁死锁舌进行保险。能有效的防止小偷拨动门舌开门。而且门里的开门钮此时也失去作用,在门里也要用钥匙才能开锁。保险安全可靠。开锁时,通过钥匙旋转,开保险凸块6,推动卡子7,簧4使挡板3回位。锁舌通过开锁凸块5,退回锁内。轴用弹性挡圈2卡在保险钮1槽内。
此门锁除具备普通碰锁的一切性能外,还可以在室内将保险滴子拨在中间,并将保险钮1拉出进行室内双保险,这样室外有钥匙也不能开锁。手伸进室内没有钥匙还是不能开锁。如暂时不需锁门,又怕别人无意中把保险滴子碰开后把门锁上,可以把锁舌退入锁腔内,保险钮拉出使挡板3上的方孔勾住锁舌进行防锁门保险。此时,不用钥匙锁舌不会出来,很适合办公室和一些公共场所使用。
