The invention discloses a gear difference and thread combined type heavy object lifting device. The gear difference and thread combined type heavy object lifting device comprises a main hollow shell.According to the device, the gear difference technology is utilized, a pinion drives a large gear to rotate, so that the effect of reducing the driving force is achieved, force reduction is achieved,the lifting degree can be gradually increased, moreover, height adjustment is achieved through the reverse threads, the adjustment effect is obvious, the mass of a lifting part can be reduced, thus the device is light in overall mass, the use cost and the manufacturing cost are low, and using and carrying are convenient; moreover, the device is provided with a longitudinal height adjustment type force reduction rotation driving mechanism with a reverse thread structure, the height adjustment effect can be achieved under the action of reverse threads, so that the torque is adjusted, the force needed during rotation is reduced, and the effect of bringing large force with small force is achieved; and in addition, the device is provided with a universal rotary part connecting mechanism with aspherical structure so that the connection of two parts can be realized, and meanwhile, the rotating function of the two parts at the connecting part cannot be influenced.

    本发明公开了一种齿轮差与螺纹组合式重物升降装置,包括主中空外壳。本发明利用齿轮差技术,以小齿轮带动大齿轮旋转,从而达到降低驱动力度的作用,实现降力,从而在起重程度上能够做到以小到大,并且,该装置利用反向螺纹实现高度调节,具有调节作用明显和降低起重部位质量的特点,所以其整体质量轻,使用成本和制造成本都比较低、方便使用和携带,而且,该装置具有反向螺纹结构纵向高度调节式降力旋转驱动机构,利用反向螺纹的作用,能够实现高度调节作用,从而调整力矩,降低旋转时需要的力度,实现以小带大,此外,该装置具有球形结构万向旋转式部件连接机构,能够在实现两部件连接的同时,又不会影响两部件在连接部位的旋转功能。
