Abstract

目前使用的房门暗锁都存在一个共同的问题:有 一斜面锁闩,在门外从门缝用薄片插拨锁闩斜面能使 锁打开。为解决此问题本实用新型在锁闩斜面设有 横向凹槽,锁扣盒斜面与锁闩斜面平行。与双锁闩保 险锁比较具有结构简单、成本低、操作简便的优点,又 有同样的保险功能。

Description

一种用于房门的新型锁闩弹子门锁属门暗锁技术领域。
现有的房门锁都有一钭面锁闩。人进出房门后能方便地把门一推(或拉)使门锁上。但往往在门外从门缝用薄片扦拨锁闩斜面,能使锁打开。为此就出现了双锁闩保险锁。锁的结构更复杂了,生产成本更高,使用时必须用锁匙旋转,使第二锁闩伸进锁扣盒,操作更繁。
本实用新型的目的是提供一种结构简单、操作简便、安全可靠,不能在门外用薄片从门缝扦拨锁闩开锁的新型门锁。
本实用新型的技术方案是对现在单锁闩门锁的两个零件进行改进,锁闩(1)斜面(2)有凹槽(3),锁扣盒侧面改为斜面(4)与锁闩斜面(2)平行。锁的其它零件结构不变。
附图1为新型锁闩弹子门锁结构示意图
附图2为锁闩结构示意图
序号1为锁闩,5为锁体,6为锁扣盒,锁扣盒内有安装加强板。锁体内有吊头板、弹簧、挚手。与流行的保险锁一样,锁上后可防止在里面用螺丝起子把锁卸下。
本实用新型是这样工作的,关、锁门时,把门推(或拉)一下,锁闩,就在锁扣盒斜面(4)上滑动,到位后在锁体内弹簧的作用下,使锁闩足够地延伸进锁扣盒内。由于锁闩斜面上有凹槽,在门外不能用薄片扦拨锁闩开锁。从而达到了结构简单、成本低、操作简便,安全可靠的发明效果。
