The invention discloses a chain-driven connecting rod lifting mechanism. The chain-driven connecting rod lifting mechanism comprises a base body, a connecting rod assembly, a top plate, a driving unit and a drive chain, wherein the lower end of the connecting rod assembly is connected with the base body, the upper end of the connecting rod assembly is connected with the top plate, and a sliding chain wheel is arranged at the lower end of the connecting rod assembly; the drive chain bypasses a fixed chain wheel and the sliding chain wheel, and then the head end and the tail end of the drive chain are fixed to the seat body; the driving unit drives the fixed chain wheel to rotate, and the fixed chain wheel and the sliding chain wheel are in chain drive through the drive chain, and the sliding chain wheel linearly slides relative to the base body while rotating under the action of the drive chain; and the connecting rod assembly rotates relative to the base body through linear sliding of the sliding chain wheel, and when the connecting rod assembly rotates relative to the base body, the height of the upper end of the connecting rod assembly changes to drive the top plate to do lifting motion. According to the lifting mechanism, the labor can be saved, the load moment required for lifting is reduced, and meanwhile, the lifting mechanism is simple in structure and small in occupied space.
本发明公开了一种链传动连杆举升机构,包括座体、连杆组件、顶板、驱动单元及传动链,连杆组件的下端与座体连接,连杆组件的上端与顶板连接,连杆组件的下端设置有滑动链轮,传动链绕过所述固定链轮及滑动链轮后其首尾两端固定在座体上,所述驱动单元驱动所述固定链轮转动,所述固定链轮与所述滑动链轮通过所述传动链进行链传动,所述滑动链轮在传动链的作用下进行转动的同时相对所述座体线性滑动,所述滑动链轮线性滑动使得所述连杆组件相对座体转动,所述连杆组件相对座体转动时所述连杆组件上端的高度发生变化带动所述顶板升降运动。本发明使得举升机构能够省力,减小举升所需的负载力矩,同时结构简单,占用空间小。
