Description

本实用新型属于一种门扣锁。
弹子挂锁用于锁门,只须将门框和门页用门扣扣上,然后将弹子挂锁锁上。虽然弹子挂锁广为用于门、窗、箱、柜、抽屉等场合,但使用时有明显缺点:一是容易被撬,通常只要将锁杆一撬即开;二是操作不便,首先得将门扣扣好,然后再将弹子挂锁落锁,开启时须重复落锁过程;三是挂锁容易丢失。
本实用新型的目的在于提供集锁和门扣一体化的防盗弹子门扣锁,这种门扣锁不易撬开,克服了挂锁的缺点。
本实用新型是用如下方式实现的:它具有普通门扣的固定扣1和搭扣2,特征是在搭扣2上装有锁芯3,还装有锁舌4与锁杆5活动相联,锁杆5一端有弹簧6,另端活动插入搭扣2上的凹口9,锁杆5中部还有用于制约其转动的固定销11;在搭扣2的弯折处具有固定销7,用铆钉8固定其弯折处。
本实用新型集锁和扣一体化。在没有钥匙的情况下不能开启,也撬不开,操作简便,设计合理,外形美观,生产工艺简单,使用方便,适用范围广,完全能取代弹子挂锁。
现结合附图对本实用新型作进一步详细说明。
图1、图2是本实用新型结构示意图;其中图1是主视图;图2是俯视图;
图3是锁舌4结构示意图;
图4是锁杆5结构示意图。
参照图1——图4,本实用新型是在普通门扣基础上作出改进,在搭扣2上装有锁芯3。以锁门为例说明:将固定扣1装在门框上,搭扣2装在门页上,锁门时将搭扣2扣在固定扣1上,这时搭扣2绕弯折处的固定销7翻转,凹口9套入固定扣1的挂耳10上,手压锁杆5,其顶端进入凹口9,这时锁舌4顶住锁杆5,弹簧6压缩,此时锁杆5已伸入凹口9挂耳10内将门锁上。开锁时,用钥匙置入锁芯3内转动,使锁舌4离开锁杆5,弹簧6伸张,锁杆5退出凹口9挂耳10,锁已开启,搭扣2绕弯折处的固定销7翻转过来,门页打开。搭扣2的弯折处用固定销7和铆钉8是为了加强搭扣2弯折处的强度,进一步加强防盗作用。
