Description

磁卡手铐
本实用新型涉及一种手铐，特别是一种具有防撬保险性能的磁卡手铐。
目前，国内均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，没有起到一种刑具的应有作用。
本实用新型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。
本实用新型是以下列形式实现的：
本实用新型的磁卡手铐由动环、基环、锁芯座、开锁环、保险杆、棘爪、片弹簧、双节链条构成，动环和基环由销子连接，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，分别与棘爪与保险杆相接合，保险杆与片弹簧相配合，保险杆端部有保险推杆。
本实用新型磁卡钥匙未插入前，二磁销相吸，锁芯座与开锁环处于“离”的状态；当磁卡钥匙插入后，二磁销相斥，锁芯座与开锁环处于“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。
本实用新型由于采用了先进的磁性技术和合理的机械机构，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，一手联动完成，使用方便；采用不锈钢制造，坚实牢固，外形美观。
附图1为本实用新型磁卡手铐结构图；
附图2为本实用新型磁卡插入时锁芯部件结构图；
附图3为本实用新型磁卡未插入时锁芯部件结构图。
下面结合附图对本实用新型实施例作一详细阐述。
如图所示，本实用新型由动环(10)、基环(11)、锁芯座(2)、开锁环(4)、保险杆(8)、棘爪(9)、片弹簧(12)、双节链条(14)构成，其中动环(10)和基环(11)由销子(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)，分别与棘爪(9)、保险杆(8)相接合，保险杆(8)与片弹簧(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)则从半径方向推出，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，先后便推动它的结合部位，其中齿(5)推动保险杆(8)的A部，齿(6)推动棘爪(9)的B部，提起棘爪(9)有齿的一端，将锁打开，手铐的动环(10)即从基环(11)中脱出，由片弹簧(12)复位。当保险推杆(13)推进后，保险杆(8)压住棘爪(9)即行锁定，并可防止用异物挑开。
本实用新型采用不锈钢制成。
