Abstract

本实用新型将螺旋式车锁固定在自行车前叉立 柱管内，锁的锁身(8)通过固定件(10)固定在自行车 前叉(1)的钢管内，锁心(6)与锁身(8)由内外螺纹连 接锁车时将钥匙投在锁内旋转三周，锁心伸出来三毫 米左右穿过三角架立柱管孔制死前叉、龙头，使自行 车固定成非平行角放置，形成撬不开、打不烂、推不走 的防盗系统。既节省又安全、简便易行。

Description

本实用新型涉及自行车的防盗安全装置。
现在自行车防盗安全装置存在锁体外露易被撬开及锁体构造复杂等问题，防盗效果差，成本高。
本实用新型发明了一种螺旋式车锁，大大简化了现行的自行车车锁的结构，降低了成本，通过与其相匹配的固定件将这种车锁固定在自行车前叉的钢管内与车体形成一个整体，达到撬不开、打不烂、推不走的防盗效果。
本实用新型的结构见附图1、2。图1是结构示意图。图2是螺旋式自行车锁的A－A示意图。（1）是自行车前叉，（2）是装在自行车上的螺旋式车锁，（3）是在三角架立柱管上开的小孔，（4）是自行车小五件，（5）是自行车龙头轴，（6）是螺旋车锁的锁心，（7）是锁心上的螺纹，（8）是锁身，（9）是三角架立柱管，（10）是固定件。
本防盗系统的最大特点是锁心（6）后部加工出外螺纹（7），锁身（8）内相应加工出内螺纹。用固定件（10）将这种特种锁固定在自行车前叉（1）内，在正对锁体的三角架立柱（9）上开孔（3）。当自行车龙头转到车锁钥匙孔正对孔（3）时，伸进钥匙顺时针方向旋转三转，锁心外伸约三毫米，将前叉、龙头和三角架立柱锁在一起。使自行车前轮和后轮成一个固定的非平行角放置，自行车骑不走也推不走。即使拖走了由于锁在钢管内也撬不开。开锁时伸进钥匙向相反方向旋转一周，锁心即缩进前叉钢管内，自行车转动自如。
这种螺旋式车锁省掉了锁舌等许多部件，结构简单、成本低廉，制造简单。安装时只要在前叉轴和三角架立柱管上打两个孔即可。可以使用在自行车、轻型摩托车和三轮车上，也可用在汽车方向盘上，应用范围较广。
