Abstract

本发明公开了一种防盗锁，包括锁体，锁体内设置着锁芯、弹簧、上弹子以及下弹子，锁芯内设置着钥匙通道，下弹子之中有至少一个锁定下弹子其下端与钥匙通道的底面相接触，其上端与锁芯顶面平齐，该锁定下弹子的高度等于钥匙通道顶面与锁芯顶面之间的径向距离加上钥匙通道的厚度；钥匙通道内配合插有一把钥匙，钥匙本体上至少设置着一个与该锁定下弹子相对应的通孔，锁定下弹子的下端穿过该通孔。本发明其结构简单，防盗效果突出，且造价低廉。

Description

一种防盗锁
技术领域
本发明涉及一种防盗锁。
背景技术
现有的防盗锁结构有很多种。趋势是防盗锁结构越来越复杂，但是这样只能提高锁具的制造成本，绝大多数情况下，只要有锁孔，就会有对应的开锁方法或者开锁工具。因此，现有的防盗锁，即使结构很复杂，其防盗、防撬效果都不是很理想。
发明内容
本发明的目的在于提供一种防盗锁，其结构简单，防盗效果突出，且造价低廉。
本发明的目的是这样实现的，一种防盗锁，包括锁体，锁体内设置着锁芯、弹簧、上弹子以及下弹子，锁芯内设置着钥匙通道，下弹子之中有至少一个锁定下弹子其下端与钥匙通道的底面相接触，其上端与锁芯顶面平齐，该锁定下弹子的高度等于钥匙通道顶面与锁芯顶面之间的径向距离加上钥匙通道的厚度；钥匙通道内配合插有一把钥匙，钥匙本体上至少设置着一个与该锁定下弹子相对应的通孔，锁定下弹子的下端穿过该通孔。
使用本发明具有特定通孔的钥匙开锁时，锁定下弹子进入该通孔内，就可以正常旋转锁芯进行开锁；除此之外，无论是使用其他钥匙或者进行技术开锁，都会被锁定下弹子阻挡住，锁定下弹子会被钥匙通道内的异物顶起进入上弹子通道内，从而锁住锁体以及锁芯，达到防止技术开锁的目的。
附图说明
下面将结合附图对本发明作进一步详细的描述。
图1为本发明的主视剖面结构示意图；
图2为本发明插入钥匙时的主视剖面结构示意图；
图3为本发明钥匙的主视剖面结构示意图。
具体实施方式
一种防盗锁，如图1、图2、图3所示，包括锁体2，锁体2内设置着锁芯5、弹簧、上弹子1以及下弹子8，锁芯5内设置着钥匙通道9，下弹子之中有至少一个锁定下弹子6其下端与钥匙通道9的底面10相接触，其上端与锁芯5顶面平齐，该锁定下弹子6的高度等于钥匙通道顶面11与锁芯顶面3之间的径向距离加上钥匙通道9的厚度；钥匙通道9内配合插有一把钥匙4，钥匙本体上至少设置着一个与该锁定下弹子6相对应的通孔7，锁定下弹子6的下端穿过该通孔。
本发明结构，锁定下弹子6下端与钥匙通道底面相接触，这样就会阻止其他开锁工具进入钥匙通道9内，杜绝技术开锁；而且，本发明的钥匙通道9可以做的很薄，这样就会杜绝暴力开锁。
而只有通过本发明具有特定通孔结构的钥匙，才能转动锁芯5进行开锁。从而大大提高了其防盗、防技术开锁性能。
