The invention relates to the technical field of thrust wheels, and discloses a thrust wheel structure convenient to replace, which comprises a first thrust wheel, a second thrust wheel and a fixing shaft, the first thrust wheel and the second thrust wheel are the same in specification and shape, the first thrust wheel is positioned on one side of the second thrust wheel, and the fixing shaft is positioned on the other side of the first thrust wheel. And the first thrust wheel and the second thrust wheel are symmetrically arranged. The threaded rod moves outwards under the spiral effect of the inner threaded pipe to drive the tensioning block to slide on the two sides in the sliding cavity, so that the arc-shaped clamping grooves and the annular clamping grooves are separated, the limiting relation to the fixing shaft is relieved, the fixing shaft can slide out from the interior of the saddle groove, and the fixing effect is achieved. And then a new fixing shaft is pushed into the saddle groove from the bottom of the saddle groove, a threaded rod is rotated to rotate towards the middle in an inner threaded pipe, a tensioning block is pushed to move, an arc-shaped clamping groove is clamped into an annular clamping groove again, and then the fixing shaft is fixedly installed.

    本发明涉及支重轮技术领域,且公开了一种便于更换的支重轮结构,包括第一支重轮、第二支重轮及固定轴,所述第一支重轮与第二支重轮的规格形状相同,且所述第一支重轮位于第二支重轮的一侧,所述第一支重轮与第二支重轮呈对称设置。通过螺纹杆在内螺纹管的螺旋作用下向外侧移动,带动张紧块在滑腔的内部两侧滑动,使得各组弧形卡槽与环形卡槽分离,从而解除对固定轴的限位关系,可将固定轴从马鞍槽的内部向下滑出,从而达到对第一支重轮及第二支重轮的快速拆卸作业,再将新的固定轴从马鞍槽底部推到其内部,再转动螺纹杆转动在内螺纹管内部向中间旋动,推动张紧块移动,使得弧形卡槽再次卡接在环形卡槽内部,从何对固定轴进行固定安装。
