Description

本实用新型属一种锁前轮的自行车锁。
现有的自行车锁有多种类型,如锁车圈的环形锁、锁车辐条的直锁和U形叉锁,还有链锁等,它们既可安装在后叉锁后轮,又可安装在前叉锁前轮。锁芯在锁体内,如需锁或开时,都得弯腰进行,不够方便。
本实用新型的目的是设计一种可在车把上锁和开的车锁,既方便又适用。
本实用新型主要由锁盒、蛇形管和锁环等组成,锁环通过铁带夹固定在前叉上,锁盒通过铁带夹固定在车把上,锁盒通过蛇形管与锁环连通。
在锁盒内,安装着锁芯,在插入钥匙后可转动。锁芯的外端钥匙门与锁盒壳面一平,锁芯的里端固定一槽轮,在槽轮上缠绕着拉筋,拉筋穿过蛇形管伸入到锁环中。在锁环中有锁舌、锁舌的伸出靠拉筋拉出,即锁上;当回转钥匙靠锁环内的拉簧使锁舌退回复位,即开锁。
在锁盒内设有定位挡片和弹簧片,锁芯槽轮端面设有定位销,当锁定时定位销转到定位挡片处停止,弹簧片卡住定位销不能回转,当开锁时,定位销越过弹簧片回转即可。
本实用新型在车把上即可实现开和锁的动作,使用操作方便,只用一只手就可以完成,盗车者不易拆卸,安全可靠。
图1和图2分别是本实用新型的主视图和左视图;
图3和图4分别是锁盒剖开状态的主视图和俯视图;
图5是锁环的剖视图。
下面结合附图将本实用新型的具体结构加以描述:
本实用新型的主要组成部分有:锁盒2、蛇形管4和锁环5,锁盒2由铁带夹1固定在车把上,在锁盒2上安装锁芯3,锁芯3的外端伸出锁壳落出钥匙门,锁芯3的里端与槽轮7固定,拉筋10一端固定并缠绕在槽轮上,拉筋的另一端通过蛇形管4内与锁舌13的里端固定,锁舌13的里端同时由拉簧6牵制。
在锁盒2内的锁芯3里端槽轮外侧,固定一定位销8,在锁盒2上设有弹簧片11和定位挡片9。当落锁时,顺时针转动钥匙,定位销9卡在弹簧片11和定位挡片9之间,拉筋10缠绕在槽轮7上,锁舌13伸出锁定;当开启时,回转钥匙,拉簧6顺势将锁舌13拉回。
