The invention provides a self-locking mechanism for a lifting machine. The self-locking mechanism comprises a driving movable flat-head rod, a driven movable flat-head rod, a movable shaft, a connecting shaft, a first U-shaped sliding block, a first installation seat, a second installation seat, a second U-shaped sliding block, a lifting linear sliding rail, a horizontal bead, a lifting table, a self-locking type anti-skid lifting rod structure, a manual electroless operation lifting rod structure, an adjustable anti-skid lifting clamping seat structure and an anti-falling bottom supporting fixed frame structure, and joints between the driving movable flat-head rod and the driven movable flat-head rod are movably connected through the movable shaft. By arranging a check ring, a lifting screw, a lifting nut, an installation lining seat, an electroless gear reducer and a hand wheel, manual lifting operation is conveniently carried out without electricity; and the hand wheel is held in hand for rotation, so that the electroless gear reducer drives the lifting screw to rotate in the installation lining seat, and the lifting nut drives the lifting table to perform a lifting action on the outer wall of the lifting screw, so that the mechanism working stability is ensured.

    本发明提供用于举升机的自锁机构,包括主动活动扁头杆,从动活动扁头杆,活动轴,连接轴,第一U型滑块,第一安装座,第二安装座,第二U型滑块,升降直线滑轨,水平珠,升降台,可自锁式防滑升降杆结构,可手动无电操作升降杆结构,可调节防滑升降夹座结构和防陷底部支撑固定架结构,所述的主动活动扁头杆和从动活动扁头杆之间的连接处通过活动轴活动连接设置。本发明挡圈,升降螺杆,升降螺母,安装衬座,无电齿轮减速箱和手轮的设置,有利于在无电情况下进行手动举升操作,通过手持手轮进行旋转,使得无电齿轮减速箱带动升降螺杆在安装衬座内部旋转,使得升降螺母在升降螺杆外壁带动升降台进行举升动作,以保证机构工作稳定性。
