Abstract

本发明是对现有自行车转向锁的改进，主要特征是设置了连为一体的手柄和锁头安全块，锁头安全块在弹簧的作用下顶住支架。本发明只能压下手柄才能锁住，防止了因外力或弹簧生锈使锁失效而产生自行车锁造成危险情况的发生。本发明适宜于各种型号自行车、助动车、摩托车等使用。

Description

一种带安全装置的转向锁
                   技术领域
本发明涉及一种自行车转向锁，更具体地涉及一种带安全装置的转向锁。
                   背景技术
目前社会上使用的自行车转向锁，都是钥匙插入锁芯旋转使锁舌进入锁紧孔中，但是钥匙一旦碰上其他物体或弹簧生绣使钥匙转动，锁舌即刻进入锁紧孔中，车把失去转向，就产生严重后果。
                   发明内容
本发明的目的在于提供一种带有安全装置的转向锁，这种锁由锁体、锁芯、钥匙、弹簧、支架、支架缺口、锁紧件、锁紧孔、手柄、锁头安全块等组成，手柄与锁头安全块连为一体，置于锁体孔内，锁头安全块在弹簧的作用下顶住支架。本发明由于设置了锁头安全块，只有在压下手柄后才能使锁舌进入锁紧孔而锁住，防止了因外力作用或弹簧生绣后使锁失效而产生危险的后果。本发明适用于各种型号的自行车、助动车、摩托车使用。
                   附图说明
附图为本发明结构示意图
                   具体实施方式
如图，本发明由锁体1、手柄2、锁芯3、钥匙4、弹簧5、锁头安全块6、支架7、支架缺口8、锁舌9、锁紧件11、锁紧孔10组成，手柄2与锁头安全块6连为一体，置于锁体孔内，锁头安全块6在弹簧5的作用下顶住支架7。使用时只有按下手柄2，锁头安全块6离开支架7，进入支架缺口8，拨动钥匙4，支架7上的锁舌9进入锁紧件11的锁紧孔10内，才能锁住自行车。
