Description

用于锁具的安全锁死机构 技术领域
本实用新型属于锁具安全的技术领域，具体而言涉及一种用于锁具的安全锁死机构。
背景技术
当前的保险箱锁具在安装时需要在箱门上设有一个通孔用来穿过连接线或者传动轴。如果拆下箱门外的输入单元，用细棒通过箱门上的通孔就可以冲击锁具或者锁壳使得锁具较薄弱的地方被敲掉，这样锁具就存在被技术开启的可能。
现有多数锁具均存在这样的问题，从箱门外面敲击锁具，锁具内部的拨盘和盖板都可能被冲掉，存在技术开启的隐患。
实用新型内容
所述锁死挡块的轴向移动被限制，
本实用新型针对现有技术的不足，提供一种使得在锁盖被冲掉的情况下，锁具零件会将锁具内锁定机构锁死的安全锁死机构。
1.为实现上述目的，本实用新型采用如下技术方案：提供了一种用于锁具的安全锁死机构，所述锁具包括盖板和锁体，所述安全锁死机构包括锁死顶杆、锁死挡块和锁死压簧，其中，
所述锁死顶杆包括限向轴和圆柱杆，所述限向轴安装在所述圆柱杆的一端，所述圆柱杆靠近所述限向轴的位置设置有凸出于所示圆柱杆并沿所述圆柱杆轴向延伸的螺旋斜面，所述锁死顶杆的另一端抵靠在所述盖板上；
所述锁死挡块上开设有异型孔，所述锁死挡块能转动地安装在所述圆柱杆上，所述异型孔套装在所述螺旋斜面的前端，所述螺旋斜面在所述异型孔中轴向运动时，带动所述锁死挡块仅做径向方向的转动；
所述锁体上开设有与所述限向轴横截面形状相同的限向槽，所述限向轴安装在所述限向槽内，并与所述限向槽周围紧贴，所述限向轴在所述限向槽内只能在轴向方向滑动，所述锁死压簧被压缩地安装在所述限向轴和限向槽的底端之间。
进一步地，所述锁具还包括支撑板，所述锁死挡块的前端和后端分别紧贴在所述支撑板和所述锁体上。
进一步地，所述异型孔内表面为与所述螺旋斜面相配合的螺旋面，所述螺旋斜面从所述异型孔经过时，所述螺旋面从动于所述螺旋斜面。
进一步地，所述盖板脱离所述锁死顶杆后，所述锁死顶杆被锁死压簧弹起，所述锁死 顶杆向前做轴向运动，所述异型孔从动于所述螺旋斜面，从而带动所述锁死顶杆做径向转动。
进一步地，所述支撑板抵靠在所述盖板上时，所述锁死挡块位于所述锁具的锁定轴的运动通道外部位置。
进一步地，所述盖板脱离所述支撑板时，所述锁死挡块转动到与所述锁具的锁定轴的运动通道相交集的位置。
进一步地，所述锁死顶杆的一端固定有所述限向轴，另一端依次穿过所述锁死挡块的异型孔和支撑板，并紧紧地抵靠在所述盖板上。
进一步地，所述锁定轴用于控制锁具的锁舌的锁止和转动。
进一步地，所述限向轴横截面形状是多边形。
进一步地，所述限向轴为圆轴，所述圆轴上开设有轴向方向的键槽，所述限向槽内壁上固定有与所述键槽配合的限位键，所述限位键能在所述键槽内沿轴向方向滑动。
