Abstract

内吸式永磁弹子锁具,锁体1上有半导磁性体块4,锁体1与锁芯2之间有磁性弹子6,钥匙3上有磁性块5,半导磁性体块4、磁性弹子6和磁性块5的极性排列为异性极排列。

Description

内吸式永磁弹子锁具
本实用新型涉及内吸式永磁弹子锁具技术领域。
现有的磁性锁在一定程度上解决了部分防盗问题,但由于磁性弹子的排列为同极性排列,在锁体上用相同导磁率的磁性弹子,从而使锁体体积增大影响了该锁的推广应用和范围。
本实用新型的目的是设计一种内吸式永磁弹子锁具,在锁体上用的弹子为半导磁性体块,弹子间的极性排列为异性极排列使锁体体积大大缩小。
本实用新型是这样实现的:锁体1内有锁芯2,锁芯2内有钥匙3,其特征是:锁体1上有半导磁性体块4,锁体1与锁芯2之间有磁性弹子6,钥匙3上有磁性块5,半导磁性体块4、磁性弹子6和磁性块5的极性排列为异性极排列。
本实用新型的优点是:设计新颖、构思巧妙、制造成本低,锁体体积大大缩小,使推广应用范围大大提高。
下面结合附图,用实施例对本实用新型做进一步说明:
附图1为开启状态图;图2为锁定状态图。
附图中:1、锁体,2、锁芯,3、钥匙,4、半导磁性体块,5、磁性块,6、磁性弹子。
当锁具处于锁定状态时,由半导磁性体块4吸引磁性弹子6在锁体1和锁芯2之间;当锁具开启时,把钥匙3插入锁芯2内由于磁性块5的磁强度大于半导磁性体块4使磁性弹子6吸入锁芯2内。
