The invention relates to a locking mechanism which comprises a locking shell, a locking connecting piece, a jacking device and a locking ball. The locking connecting piece is arranged at the end of the locking shell in a sleeving manner, a locking hole is formed in the end of the locking shell, the locking ball is arranged in the locking shell and can partially extend out of the locking hole, andwhen the locking ball partially extends out of the locking hole, the locking shell and the locking connecting piece are relatively locked. The jacking device comprises a jacking block and a jacking rod, the jacking block is used for jacking the locking ball out of the locking hole, the jacking block is provided with a jacking groove matched with the locking ball, and in the moving process of the jacking device between the locking position and the unlocking position, the locking ball and the jacking groove are in line contact fit. The locking mechanism is small in deformation and stable in structure. The technical problems that in the prior art, a small ball extruded out of a locking hole is prone to deformation, and consequently locking is not smooth and even fails are solved.

    本发明涉及一种锁止机构,包括锁定壳体、锁定连接件、顶升装置和锁定球;所述锁定连接件套设于所述锁定壳体端部,所述锁定壳体端部设有锁定孔,所述锁定球设于所述锁定壳体且能够通过锁定孔部分地伸出,当所述锁定球部分伸出所述锁定孔时,所述锁定壳体和所述锁定连接件相对锁定;所述顶升装置包括顶出块和顶升杆,所述顶出块用于将所述锁定球顶出所述锁定孔,所述顶出块具有与所述锁定球配合的顶出槽,所述顶升装置在所述锁定位置和所述解锁位置之间移动过程中,所述锁定球与所述顶出槽为线接触配合。本发明提供了一种变形小、结构稳定的锁止机构。解决了现有技术中挤出锁定孔的小球容易变形,导致锁止不顺畅甚至锁止失败的技术问题。
