Description

磁卡手铐 技术领域
本发明涉及一种手铐， 特别是一种具有防撬保险性能的磁卡手铐。
背景技术
目前， 大多采用一种传统的机械结构手铐， 它利用齿轮或棘轮原理把罪 犯的双手或单手铐住， 其产品取材较差， 结构笨重， 原理单一， 钥匙齿形直 观， 容易被异物挑开， 往往造成失灵， 没有起到警具应有的作用。
发明概述
本发明的目的是针对现有技术的不足， 采用先进的磁性技术和合理的机 械结构， 提供一种防撬保险性能优越的磁卡手铐。
本发明是采用以下结构实现的：
本发明的磁卡手铐由动环、 基环、 锁芯座、 开锁环、 保险杆、 双棘爪、 双片簧和链条构成， 动环和基环由中轴连接， 锁芯座中间有二个相对应的磁 销， 锁芯座外圈有开锁环， 开锁环上有两个齿， 分别与双棘爪和保险杆相接 合， 保险杆与双片簧相配合， 保险杆端部有保险推杆， 由双片簧压住双棘爪。
本发明磁卡钥匙未插入前， 二磁销相吸， 锁芯座与幵锁环处于 "离" 的 状态； 当磁卡钥匙插入后， 二磁销相斥， 锁芯座与幵锁环处于 "合" 的状态。 当钥匙顺时针转动时， 推开保险杆启锁， 当钥匙逆时针转动时， 锁芯座复原， 保险杆不动。 磁卡钥匙插入不正确或用其他异物插入， 锁芯自由转动不能开 锁。
本发明由于采用了先进的磁性技术和合理的机械结构， 提高了防撬保险 性能； 在磁卡钥匙插入和转动中， 拉开保险杆和开锁一手连动完成， 使用方 便。
本发明的目的、 优点和特征将通过以下结合一个较佳实施例的描述而变 得清楚。
附图简要说明
图 1是根据本发明一较佳实施例的磁卡手铐的结构图；
图 2是磁卡插入时锁芯部件的结构图； 图 3是磁卡未插入时锁芯部件的结构图。
对较佳实施例的描述
如图所示， 根据本发明一较佳实施例的磁卡手铐由动环 10、 基环 1 1、 锁 芯座 2、 开锁环 4、 保险杆 8、 双棘爪 9、 双片簧 12。 双节 （或三节） 链条 14 构成。 动环 10和基环 1 1 由中轴 7连接。 锁芯座 2中间有二个相对应的磁销 3。 锁芯座 2外圈有开锁环 4， 开锁环 4上还有两个齿 5、 6， 分别与双棘爪 9、 保 险杆 8相接合。 保险杆 8与双片簧 12相配合， 保险杆 8端部有保险推杆 13。
当磁卡钥匙 1未插入前， 二磁销 3相吸， 锁芯座 2与开锁环 4处于 "离" 的状态。
当磁卡钥匙 1插入锁芯座 2时， 由于磁力的作用， 磁销 3从半径方向推 出， 锁芯座 2与开锁环 4便结合成一体。 随后转动钥匙， 开锁环 4上的二个 齿便先后推动它的接合部位， 其中齿 5推动保险杆 8的 A部， 齿 6推动双棘 爪 9的 B部， 提起双棘爪 9有齿一端， 将锁打开， 手铐的动环 10即从基环 1 1 中脱出， 由双片簧 12复位。 当保险推杆 13推进后， 保险杆 8压住双棘爪 9 即行锁定， 并可防止用异物挑开。
本发明的磁卡手铐采用不锈钢制成， 可使手铐更加坚实牢固， 外形更加 美观。 当然也可以用其它适当的材料制成。
