Abstract

本实用新型公开了一种防盗锁,由锁体、锁心部件、锁舌、锁栓组成。它是在现有弹子挂锁的基础上,将锁体改为一面封闭的槽形几何腔体,把暴露在锁体外面的U形锁栓设计成圆柱体,其两端部安放在空腔中部两壁的栓孔中,把锁栓及门孔鼻都封闭在锁体槽形腔内,构成封闭式结构的防盗锁。该锁具有防撬、防钳断的功能,适合于门、农用三轮车、农用四轮拖拉机使用,是目前防盗锁的一种最佳设计。

Description

防盗锁
本实用新型涉及一种防盗锁,适合于单扇门、双扇门、农用三轮车、农用四轮拖拉机使用。
现在市场上出售的弹子挂锁,由锁体、锁心部件和U型锁栓组成,它结构简单、使用方便,但存在的不足之处是U型锁栓暴露在锁体外面,容易被撬开,也容易用剪钢板钳钳断,造成财产失窃。
本实用新型的任务是设计一种防盗锁,同时具有防撬、防钳断功能。
本实用新型的任务是这样实现的:设计一种防盗锁由锁体、锁心部件、锁栓、锁舌组成。几何形状的锁体为一面封闭的槽形腔体,外形可作成长方形、正方形、梯形等,内腔制成长方槽形,椭圆槽形等。锁栓位于空腔中部两边的壁体中,锁栓在空腔内的中间部分,将来与孔鼻连通,把锁栓、孔鼻都封闭在锁体腔内。锁栓为圆柱体,它的头部有栓帽,栓帽后装弹簧,尾部有凹槽,与锁舌相连。当拧动锁心部件,拉动锁舌退出锁栓尾部凹槽时,锁栓在弹力作用下弹出,锁被打开。锁栓靠锁体中的弹性卡销卡在栓尾凹槽内,使锁栓停在锁体边孔中。
本实用新型的优点是防盗锁的锁心部件、锁舌、锁栓的两端均装在锁体内,封闭的槽形腔又把锁栓和孔鼻封闭起来,可防止锁栓被撬,被钳断,防盗效果良好。
下面结合附图对本实用新型实施方式进行详细说明:
图1是防盗锁主示图
图2是防盗锁俯视图
图3是防盗锁左视图
参照图1、图2,说明防盗锁各部件在锁体中的安装位置。在以一个面封闭的槽形腔体的锁体(1)上,锁栓(3)从锁栓孔(12)插入穿过椭圆形空腔(10)中部进入锁栓孔(13)中,锁栓(3)与锁舌(5)垂直连接,锁舌(5)与锁心部件(7)垂直连接。锁栓(3)为圆柱体,其头部制有栓帽(9),在栓帽后边套装弹簧(2),锁栓尾部制有凹形槽(11)。当锁栓通过栓孔(12)进入锁体时,锁栓帽(9)压缩弹簧(2),锁栓尾部进入栓孔(13)中,锁舌(5)在锁舌弹簧(6)力作用下,使锁舌进入锁栓尾部的凹槽(11),锁栓被锁定。用钥匙转动锁心部件(7),拉动锁舌(5)退出凹槽(11),锁栓在弹簧(2)的作用下脱离栓孔(13),在锁栓尾部到达栓孔(12)时,弹性卡销(4)进入凹槽(11)中,卡住锁栓,使锁栓不与栓孔(12)脱离,锁栓被打开。销钉(8)用于封堵锁舌尾部弹簧。
图3是防盗锁左视图,说明锁体封闭面(14)的位置。当防盗锁锁定时,锁栓(3)穿过孔鼻(15)的状态。锁体把锁栓、门的孔鼻封闭在锁体空腔内,构成封闭式结构的防盗锁。该锁具有很强的防撬、防钳断功能。
