The invention belongs to the technical field of lifting tables, and particularly relates to a mechanical type small lifting table. The mechanical type small lifting table comprises a lifting plate anda cross lifting frame arranged on the inner side of the lifting plate, the lifting plate comprises a top plate and a bottom plate which are distributed in parallel, a hinge base and a mounting base are arranged on the opposite side faces of the top plate and the bottom plate, the hinge base is fixed to one end of the lifting plate, the mounting base is located on the other end of the lifting plate, the cross lifting frame is driven by a rapid adjusting hand wheel to lift, after the general height is adjusted, a locking mechanism is pressed down, a second sliding sleeve and a sliding base arelocked, through the locking mechanism, unlocking between the sliding base and a first sliding sleeve is carried out, the first sliding sleeve and the sliding base are in the sliding state, at the moment, a fine rotary knob is rotated, the cross lifting frame is driven by the fine rotary knob to lift, fine adjusting is finished, a rough adjusting screw in the structure is higher in transmission efficiency compared with a common screw rod, therefore, adjusting can be more rapidly carried out, and fine adjusting can be carried out.
本发明属于升降台技术领域,尤其为机械式小型升降台,包括升降板以及设置于升降板内侧的交叉升降架,所述升降板包括平行分布的顶板和底板,所述顶板、底板的相对一侧面均设有铰接座和安装座,所述铰接座固定于所述升降板的一端,所述安装座位于所述升降板的另一端;使交叉升降架在快调手轮的带动下升降,调节好大致高度后,然后按下锁死机构,将第二滑套与滑座之间锁死,然后通过锁死机构将滑座与第一滑套之间解锁,使第一滑套与滑座之间处于滑动状态,此时,可以转动精细旋钮,使交叉升降架在精细旋钮的带动下升降,完成精细调节,本结构中粗调螺杆相对于普通螺杆,传递效率更高,因此可以更快的进行调节,并可以精细调节。
