The invention relates to a locking device with a limiting mechanism. The locking device comprises a first lock body, a locking assembly and a second lock body, wherein the locking assembly comprises alocking shell, a driving rod and a locking piece, the locking shell is provided with a locking hole, and the driving rod is located in a cavity of the locking shell and drives the locking piece to extend out or retract relative to the locking hole; the locking assembly comprises a locking shell and a driving rod, a limiting sleeve is arranged in the locking shell, a sleeve through hole is formedin the limiting sleeve, the locking assembly further comprises a jacking ball, the jacking ball is arranged at the upper end of the driving rod, and the inner diameter of the limiting sleeve is smaller than the outer diameter of the jacking ball. The locking device with the limiting mechanism for limiting the position of a big ball is advantaged in that a technical problem that in the prior art, in the replacement process, when a driving rod is unscrewed, a large ball is prone to being disengaged from a locking mechanism, and consequently parts are lost is solved.
本发明涉及一种具有限位机构的锁止装置,包括第一锁体、锁止组件和第二锁体;所述锁止组件包括锁止外壳、驱动杆和锁定件,所述锁止外壳具有锁定孔,所述驱动杆位于所述锁止外壳腔内且驱动所述锁定件相对于所述锁定孔伸出或者缩进;所述锁止外壳内设有限位套筒,所述限位套筒设有套筒通孔,所述锁止组件还包括顶升球,所述顶升球设于所述驱动杆的上端,所述限位套筒的内径小于所述顶升球的外径。本发明提供了一种具有限制大球位置的限位机构的锁止装置。解决了现有技术中在更换过程中,拧下驱动杆时,大球容易从锁止机构中脱离,造成零件丢失的技术问题。
