The invention discloses a gear and rack lifting mechanism which comprises a mounting box and a bracket located above the mounting box, a rack is arranged in the mounting box in an up-down sliding mode, the top of the rack penetrates through the mounting box and extends to the outside of the mounting box, and the invention relates to the technical field of lifting mechanisms. According to the gear and rack lifting mechanism, the rack is arranged in the mounting box in an up-down sliding mode, the meshing state between the first gear and the rack is utilized, the control mechanism is arranged on the mounting box in a matched mode, and the control mechanism controls the rotating shaft to rotate, so that the first gear drives the rack to ascend and descend; compared with a traditional direct gear and rack meshing transmission process, other gears, ratchet wheels and pawls are involved, stability is higher, the lifting height can be automatically locked, manual operation is not needed, operation can be rapidly conducted when the locking state is unlocked, and the novel gear and rack lifting mechanism is higher in practicability.

    本发明公开了一种齿轮齿条升降机构,包括安装箱以及位于安装箱上方的托架,所述安装箱的内部可上下滑动设置有齿条,所述齿条的顶部贯穿安装箱并延伸至安装箱的外部,本发明涉及升降机构技术领域。该齿轮齿条升降机构,通过在安装箱的内部可上下滑动设置有齿条,利用第一齿轮与齿条之间的啮合状态,配合安装箱上设置有控制机构,利用控制机构控制转轴转动,使得第一齿轮带动齿条升降,相对于传统的直接通过齿轮齿条的啮合传动过程,介入了其余齿轮和棘轮棘爪,稳定性更强,并且能够对升降高度自动进行锁止,无需人工操作,解除锁定状态时,也能快速进行操作,新型的齿轮齿条升降机构,实用性更强。
