Description

双珠斜契式加固锁
本实用新型涉及一种锁具,特别是用于铁路货运防止货物丢失用的双珠斜契式加固锁。
根据铁路货运部门信息反馈,货车货物丢失严重,目前所使用的货车车厢的铁丝捆扎法已不足以防止货物的丢失。
本实用新型之目的是针对前述现有技术的不足而公开一种结构简单,成本较低,能较好防止货物被盗,产生较好的社会效益和经济效益的双珠斜契式加固锁。
本实用新型是按如下方式实现的:双珠斜契式加固锁的构造特征在于:锁头2上有两个斜孔,在斜孔中装有弹簧4和钢珠5,在两斜孔的对称轴上有与锁杆1直径相同的孔,在该孔中装入一个塑料套3,锁杆1的一端为凸缘另一端带有凹槽。
本实用新型的积极效果是:本加固锁结构简单,易于制造,使用起来方便而牢靠,能较好防止货物被盗,产生较好的社会效益和经济效益。
附图说明如下:
图1是本实用新型的结构图。
图2是本实用新型的锁头的结构图。
图3是本实用新型的锁杆的结构图。
其中:
1、锁杆    2、锁头    3、塑料套    4、弹簧
5、钢珠
以下结合附图对本实用新型作进一步详细说明:
如图1、2、3所示。双珠斜契式加固锁的构造特征在于:锁头2上有两个斜孔,在斜孔中装有弹簧4和钢珠5,在两斜孔的对称轴上有与锁杆1直径相同的孔,在该孔中装入一个塑料套3,锁杆1的一端为凸缘另一端带有凹槽。在使用时,将锁头2和锁杆1对准门扣,将锁杆1插入锁头2的孔中,在插入的过程中塑料套3被顶出,同时钢珠2卡入锁杆1的凹槽中,这时车门已被锁好,如欲开门,只能用专用工具将锁杆1剪断,否则门无法开启,从而达到较好的防盗目的。
