Abstract

一种弹子锁具，包括装配在锁体壳（1）内的锁舌（2）、弹子（3）、锁止块（4）；锁体壳（1）上设有斜面槽（11）、插孔（12），弹子（3）装配在斜面槽（11）内与锁止块（4）的一端相连，锁舌（2）***插孔（12）内受弹子（3）的限位，当锁舌（2）上下移动时会对弹子（3）产生推力；该锁具结构简单生产方便。

Description

一种弹子锁具结构 技术领域
本实用新型涉及一种锁具，更具体的说，涉及一种弹子锁具结构。
背景技术
目前，市场上常见的锁具结构比较复杂，零部件多、成本高。
技术问题
技术解决方案
本实用新型的目的是为了提供一种弹子锁具结构，其结构简单、可靠性好、生产成本低。
为了达到上述目的，本实用新型的技术方案如下：
一种弹子锁具结构，其特征在于：包括装配在锁体壳1内的锁舌2、弹子3、锁止块4；锁体壳1上设有斜面槽11、插孔12，弹子3装配在斜面槽11内与锁止块4的一端相连，锁舌2***插孔12内受弹子3的限位，当锁舌2上下移动时会对弹子3产生推力。
所述弹子3为可以滚动的球体。
所述弹子3对锁舌2的限位方法不限于以下情况：锁舌2上设有缺口21，弹子3与缺口21相配合；缺口21还可以是半球形状。
为了更好的节省空间，锁止块4与弹子3相连的一端呈斜面结构。
考虑到实际使用中锁舌2易于拔出和***锁体壳1，可以在锁舌2的顶部设有圆弧端。
由于采用了上述结构，从而提高了锁具的安全性、可靠性，且结构简单、精致小巧，适合大范围的推广和应用。
 有益效果
附图说明
图1为锁舌***锁体壳内，锁定状态剖面示意图；
图2为锁舌拔出锁体壳外，开锁状态剖面示意图。
 本发明的最佳实施方式
本发明的实施方式
下面结合附图和实施例对本实用新型作进一步详细的说明：
一种弹子锁具结构，其特征在于：包括装配在锁体壳1内的锁舌2、弹子3、锁止块4；锁体壳1上设有斜面槽11、插孔12，弹子3装配在斜面槽11内与锁止块4的一端相连，锁舌2***插孔12内受弹子3的限位，当锁舌2上下移动时会对弹子3产生推力。
如图1所示，为锁舌2***锁体壳1的插孔12内，锁定状态示意图；当锁止块4受到外力作用向上移动时，锁止块4的顶端推动弹子3在斜面槽11内向上运动，使弹子3与锁舌2上的缺口21相配合，锁舌2受到弹子3的限位无法上下移动，保持锁紧状态。
如图2所示，为锁舌2拔出锁体壳1的插孔12外，开锁状态示意图；当锁止块4受到外力作用向下移动时，锁止块4对弹子3的阻力消失，此时，外界对锁舌2施加向上的拉力，锁舌2向上运动时会推动弹子3向下运动，同时，由于弹子3所处的槽位为斜面槽，且弹子3为可以滚动的球体，所以弹子3受自身重力和锁舌2向上运动时产生的推力向下滚动，此时，弹子3不再对锁舌2限位，锁舌2可以顺利拔出锁体壳1上的插孔12，达到开锁的目的。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但不能因此而理解为对本实用新型专利范围的限制；应当指出的是，对于本领域的技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些变形和改进都属于本实用新型的保护范围；因此，凡跟本实用新型权利要求范围所作的等同变换与修饰，均应落在本实用新型权利要求的保护范围之内。
