Abstract

本实用新型涉及一种U型锁,该锁包括锁体、锁芯和U型锁杆,其特征是锁体4为实心管子,锁体一端挖空,锁芯8和锁扣5安装在空腔中,锁体另一端开有槽9,活动圆柱销3穿过槽8定位在锁体上,U型锁杆2一端插入活动圆柱销中并由弹性销钉1将U型锁杆与活动圆柱锁固定一起。本U型锁具有较强的使用强度,安装牢固,使用可靠、不易破坏等优点。

Description

U型锁
本实用新型涉及一种U型锁。
U型锁一般由锁体、U型锁杆和锁芯三部分组成。目前市售的U型锁,其锁体为空心管子,锁杆一端装上塑料座后,再将塑料后座装入空心管子一端用小铆钉固定。锁芯用锁扣、弹簧装好后再装入空心管子另一端内,用小铆钉固定。这种U型锁由于使用方便,曾一度受到用户欢迎,广泛用作自行车之类的车锁。但同时存在以下缺陷:一是锁体为空心管子,强度差,易变形,尤其是锁杆和塑料连接部分易发生折裂,二是空心管子壁太薄,使固定锁杆和锁芯的小铆钉易脱落。这些缺陷使锁的防盗性差,容易被人破坏。
本实用新型目的在于提供一种锁体强度好,锁杆安装牢固,具有较好使用效果的新颖U型锁。
为实现上述发明目的,本实用新型采用以下技术方案:锁体4为实心金属管子,锁体一端挖空,锁芯8和锁扣5安装在空腔中,锁体另一端开有槽9,活动圆柱销3穿过槽9并定位在锁体上,U型锁杆2一端插入活动圆柱销中并由弹性销钉1将U型锁杆与活动圆柱销固定一起。
由于本U型锁采用实心锁体,且锁扦通过活动圆柱销固定在锁体上,因而具有较强的使用强度,安装牢固,使用可靠,不易破坏等优点。
下面结合实施例及其附图对本实用新型技术内容作进一步说明。
图1是本实用新型实施例结构示意图。
图2是图1A向剖视图。
图3是图2B向视图。
如图所示,锁芯8和锁扣5用弹性销6连接一体,装在锁体4一端的空腔中,并由小铆钉7固定在锁体4上,锁体另一端开有槽9,活动圆柱销3穿过槽9并定位在锁体上,U型锁杆2一端插入活动圆柱销中并由弹性销钉1将锁杆与活动圆柱销固定一起。本实施例的锁体可采用铝合金之类的实心金属管子。
