Description

本实用新型为保险防盗自行车锁,属于自行车专用锁。
现有的自行车锁,为两片铆合结构,一撬即开。近年有许多防盗锁问世,但锁环(锁杆)只锁尾,不锁头,仍然用力可以撬开,并不保险,且成本很高。
本实用新型的目的在于提供一种锁杆尾部铰连、头部锁定、任何手动工具和人力无法撬开,且耐锯、钻、砸,成本低廉的保险防盗自行车锁。
本实用新型提供的保险防盗自行车锁如附图所示:弹子锁头(1)装于上下两片辉光碰焊的锁环(2)左腔中,内锁芯尾装有锁卡(3),锁环(2)右端铰连锁杆(4),锁杆(4)头部有方孔,转动内锁芯锁卡(3)即插入孔内,锁杆(4)被上、下、左、右、前、后6面锁定。锁环(2)和锁杆(4)上片及锁卡(3)铰连肖内肖(5)均用45钢淬硬,无法锯、钻。
本实用新型与现有防盗自行车锁相比,因锁杆(4)尾部铰连,又有淬硬内肖加固,头部有方孔6方位锁死,是任何手动工具无法撬开的,唯一弹子锁头(1)可钻,但锁卡(3)也不能退出;结构简单,成本仅2元余。
