Abstract

麻花芯防盗锁,其锁芯上的匙槽是以锁芯端面平面中心为轴心,以匙槽宽中点到轴心的距离为半径,环绕锁芯沿进深方向作螺旋型旋转,每处锁体上的弹子孔的方向均与该处匙槽方向向对应,即形成麻花芯防盗锁。

Description

麻花芯防盗锁
技术领域
本实用新型涉及一种防盗锁,特别是能提高锁具防盗性能的麻花芯防盗锁。
背景技术
当前,公知的防盗锁锁芯,匙槽一般与匙孔平行,且是一直型,钥匙容易仿制,或锁具容易被打开。不利于防盗作用的发挥。
发明内容
本实用新型的目的是要提供一种,麻花芯防盗锁,它锁芯上匙槽的方向随着匙孔深度的变化而改变,匙槽从匙孔口开始,绕锁芯旋转,使匙槽在进深方向在锁芯的圆柱面上位置发生改变,这样就增加了钥匙的仿制难度,或难以用替代品把锁打开,提高了防盗锁的安全性能。
本实用新型的目的是这样实现的:将麻花芯防盗锁锁芯上的匙槽,按锁芯端面平面的中心为轴心,以匙槽宽中点到轴心的距离为半径,环绕锁芯沿进深方向作螺旋型旋转,形成了麻花形匙槽。匙槽旋转后发生扭曲,所对应在锁体上的同一列每个弹子孔的方向均不向同,这样就提高了钥匙的仿制难度,或难以用替代品把锁打开,提高防盗锁的安全性能。
附图说明
图1是麻花芯防盗锁锁芯端面平面图,图2是麻花芯防盗锁锁芯立面图,两图示包括端面平面(1),匙槽(2)。
具体实施方式
麻花芯防盗锁锁芯匙槽,是以锁芯端面平面(1)中心为轴心,以匙槽(2)宽中点到轴心的距离为半径,环绕锁芯沿进深方向作螺旋型旋转,形成扭曲型匙槽(2),每处锁体上的弹子孔的方向均与该处匙槽方向向对应,即形成麻花芯防盗锁。

Claims (1)

1.一种防盗锁,其特征是锁芯上的匙槽(2),是以锁芯端面平面(1)中心为轴心,以匙槽(2)宽中点到轴心的距离为半径,环绕锁芯沿进深方向作螺旋型旋转。
