The utility model discloses a mechanical type elevating gear with rack and pinion jacking structure, this elevating gear mainly comprise last mesa, circle support, lower mesa, interior cantilever crane, boom, gear, rack, motor, organ formula dust cover. The motor drives gear revolve, and the rack that the gear drove the meshing moves from top to bottom, and rack upper end top is supported at the circle of last mesa, when the rack upwards moves, drives the circle and supports upwards operation, goes up the mesa and rises, when the rack moves downwards, go up the mesa and at the uniform velocity descend realization elevating gear's rising and decline down in self weight effect. Then elevating gear operation of gear revolve, gear stall then elevating gear keeps static. Advantages such as this elevating gear has simple structure, simple to operate, processing ease, the operation is stable, the cost is lower, safety is dustproof. 本实用新型公开了种带有齿轮齿条顶升结构的机械式升降装置，该升降装置主要由上台面、圆支撑、下台面、内臂架、外臂架、齿轮、齿条、电机、风琴式防尘罩所组成。电机带动齿轮转动，齿
