The invention relates to the technical field of lifting driving devices, and discloses a chain type jacking mechanism which comprises a rack, a lifting table is arranged on the rack, and the lifting table is vertically and slidably connected with the rack; a chain is arranged in the chain winding seat, and the outer end of the chain extends out of the upper end of the chain winding seat and is fixedly connected with the lifting table; the chain bypasses the driving chain wheel and is meshed with the driving chain wheel, and the driving chain wheel is configured to be driven by external power to rotate so as to control the chain to extend out of or retract into the chain winding seat; the chain is configured to be capable of being bent only on one side, so that the chain only has a single-side bent state and a linear state, the portion, located outside the chain winding base, of the chain is in the linear state and is parallel to the movement direction of the lifting table, and the portion, located inside the chain winding base, of the chain is in the single-side bent winding state. The linear displacement mechanism has the beneficial effects of stable and compact structure, small occupied space and large linear displacement stroke.

    本发明涉及升降驱动装置技术领域,公开了一种链式顶升机构,包括机架,机架上设有升降台,升降台与机架竖向滑动连接;链条收卷座,链条收卷座内设有链条,链条的外端从链条收卷座的上端伸出并与升降台固定连接;以及主动链轮,链条绕过主动链轮与主动链轮啮合,所述主动链轮被配置为通过外部动力驱动旋转进而控制链条从链条收卷座内伸出或缩入;链条被配置为仅能够单侧弯曲,使得链条仅具有单侧弯曲状态和直线状态这两种状态,位于链条收卷座外部的链条处于直线状态且与升降台的运动方向平行分布,位于链条收卷座内部的链条处于单侧弯曲的收卷状态。本发明具有结构稳定紧凑、占用空间小、直线位移行程大的有益效果。
