Abstract

一种具有防撬功能的锁芯。它是在锁体外壳中,锁芯套在圆管中,其底部装一压力弹簧,圆管固定于外壳中,锁芯末端固定一锁梁,设一环型轨道于圆管外壁,使两销钉对称穿过锁体外壳销入轨道内,用一铆钉穿过锁体外壳并铆入圆管外壁内0.5-1.0毫米深。当用钥匙开锁芯时,锁芯转动九十度并弹起,同时带动锁梁退回。当暴力开锁芯时,圆管撑开铆钉并转动,锁芯相对于圆管并没有转动仍固定在圆管内。起到防撬作用。

Description

锁芯
技术领域
本发明涉及一种锁芯,尤其是具有防撬功能的锁芯。
背景技术
目前公知的锁芯是在锁体外壳中,锁芯套在圆管中,圆管固定于外壳中,锁芯末端固定一锁梁,其底部装一压力弹簧。开启锁芯时,其转动九十度并弹起,同时带动锁梁退回。但撬锁也是用暴力转动锁芯而开锁的。一般的锁芯很容易打开,没有防撬功能,容易给使用者带来损失。
发明内容
为防止现有锁芯容易撬开的不足,本发明提供一种锁芯,该锁芯不仅结构简单,而且具有放撬功能。
本发明解决其技术问题所采用的技术方案是:在锁体外壳中,锁芯套在圆管中,圆管固定于外壳中,锁芯末端固定一锁梁,其底部装一压力弹簧,设一环型轨道于圆管外壁,使两销钉对称穿过锁体外壳销入轨道内,用一铆钉穿过锁体外壳并铆入圆管外壁内0.5-1.0毫米深。当用钥匙开锁芯时,锁芯转动并弹起,同时带动锁梁退回。当暴力开锁芯时,圆管撑开铆钉并转动,由于锁芯相对于圆管并没有转动,从而达到防撬的目的。
有益效果是,不仅结构简单,而且具有防撬功能。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是锁芯实施例结构图。
图2是圆管的侧面视图。
图1.锁芯,2.圆管,3.锁体外壳,4.销子,5.铆钉(1),6.销钉,7.弹簧(1),8.铆钉(2),9.铆钉(3),10.弹簧(2),11.锁梁,12.环型轨道,13.销钉,14.直角轨道。
在图1中,锁芯(1)、安装于圆管(2)中,其底面装一弹簧(10)、圆管(2)安装在锁体外壳(3)中,锁梁(11)由铆钉(9)固定于锁芯(1)上,销钉(6)和销钉(13)穿过锁体外壳(3)销于环型轨道(12)内,铆钉(8)穿过锁体外壳(3)铆于圆管(2)中,在圆管(2)中的销子(4)销在直角轨道(14)中,其末端由弹簧(7)和铆钉(5)固定。

Claims (2)

1.一种锁芯,在锁体外壳中,固定在圆管内的锁芯,其末端固定有锁梁,并且底部装有弹簧,销子销于锁芯直角轨道内,其特征是:圆管外壁有环型轨道,铆钉固定圆管。
2.根据权利要求的1所述的锁芯,其特征是:铆钉穿过锁体外壳铆入圆管内0.5-1.0毫米深,环型轨道设在圆管外壁,并有销钉穿过锁体外壳销在锁体内。
