The invention belongs to the technical field of bicycle frames, and discloses a stable bicycle frame which comprises a bicycle body, a fixing frame is movably connected to one side of the bicycle body, a wheel is movably connected to the middle of the bottom of the fixing frame, and fixing assemblies are movably connected to the front side and the rear side of the middle of the wheel in a clamped mode. The other side of the fixing assembly is fixedly connected with a lubricating assembly; through cooperation of structures such as a limiting block, a limiting hole, a clamping column and a first spring, the device facilitates mounting and dismounting of a wheel, the limiting block rotates along an arc-shaped groove, an arc-shaped groove block of the limiting block is clamped with a rotating shaft of the wheel, the arc-shaped groove block is located at the bottom of the rotating shaft of the wheel at the moment, and the clamping column slides downwards along the limiting groove; the clamping column abuts against the inclined groove of the limiting block, the first spring shrinks and becomes short, and when the clamping column and the limiting hole are horizontal, the clamping column can be inserted into the limiting hole through the elastic force of the first spring, so that the device is convenient to mount and dismount.

    本发明属于自行车车架技术领域,且公开了一种稳固型自行车车架,包括车体,所述车体的一侧活动连接有固定架,所述固定架底部的中部活动连接有车轮,所述车轮中部的前后两侧均活动卡接有固定组件,所述固定组件的另一侧固定连接有润滑组件;本发明通过限位块、限位孔、卡柱、第一弹簧等结构配合使得装置便于车轮的安装拆卸通过将限位块沿着弧形槽旋转,使得限位块的弧形槽块与车轮的转轴卡接,此时弧形槽块位于车轮转轴的底部,通过将卡柱沿着限位槽向下滑动,卡柱与限位块的斜槽抵接,第一弹簧收缩变短,当卡柱与限位孔位置水平时,卡柱通过第一弹簧的弹力能够插入限位孔,使得装置便于安装拆卸。
