The invention discloses a mechanical lifting wheel which comprises a connecting base, a rolling wheel and a lifting assembly. The roller is rotationally connected to the connecting base. The lifting assembly comprises a handle, a rotating shaft and a supporting seat, the upper end of the rotating shaft is rotationally connected with the connecting seat, the lower end of the rotating shaft is in threaded connection with the supporting seat, an annular rack is arranged on the peripheral wall of the rotating shaft, and a reversing assembly is arranged in the handle and provided with a first tooth part and a second tooth part; when the first tooth part is meshed with the annular rack, the handle is rotated to enable the rotating shaft to rotate around the axis of the rotating shaft in the first direction, the supporting base moves downwards relative to the rotating shaft, the supporting base gradually makes contact with the ground and supports the rolling wheel, the rolling wheel is separated from the ground, and therefore the contact area of the mechanical lifting wheel and the ground is increased. According to the mechanical lifting wheel, the rollers can be separated from the ground when the mechanical lifting wheel is static, and the supporting seats replace the rollers to support the whole mechanical lifting wheel, so that the contact area between the mechanical lifting wheel and the ground is increased, and the mechanical lifting wheel can be stably static on the ground.
本发明公开了一种机械式升降轮,包括连接座、滚轮和升降组件。滚轮转动连接于连接座。升降组件包括手柄、转轴和支撑座,转轴的上端与连接座转动连接,转轴的下端与支撑座螺纹连接,转轴的外周壁设有环形齿条,手柄内设有换向组件,换向组件具有第一齿部和第二齿部;当第一齿部与环形齿条啮合时,转动手柄以使转轴绕自身轴线沿第一方向转动,支撑座相对于转轴向下移动,支撑座逐渐与地面接触并撑起滚轮,使得滚轮与地面分离,从而增加机械式升降轮与地面的接触面积;该机械式升降轮能够实现在静止时滚轮脱离地面,支撑座取代滚轮以支撑整个机械式升降轮,从而提高与地面的接触面积,保证机械式升降轮能稳定地静止于地面上。
