The invention discloses a bidirectional buffering gravity wheel. The bidirectional buffering gravity wheel comprises a wheel body and a wheel assembly; the wheel body is rotatably arranged in the wheel assembly; the wheel assembly is provided with a wheel shaft, a pressure bearing sheet, an adjusting switch, a brake column, a brake block, a limiting block and a nitrogen cylinder; the brake columnis positioned in the pressure bearing sheet; the brake block is positioned at the bottom of the brake column; the adjusting switch is arranged at the bottom of the pressure bearing sheet in an up-and-down sliding manner; a clamping block is arranged in the middle of the wheel shaft; the part, located below the clamping block, of the wheel shaft is arranged in the brake column; and the part, located above the clamping block, of the wheel shaft is arranged above the pressure bearing sheet; and the limiting block and the nitrogen cylinder are arranged at the end, away from the adjusting switch, of the brake column. The gravity wheel is reasonable in design. A user can have enough time to adjust an optimal position until the gravity wheel is completely locked when using the gravity wheel; switching between a gravity wheel and a sliding wheel can be achieved; operation is convenient; and adjustment and control can be achieved just with operation of the adjusting switch required.

    本发明公开了一种双向缓冲重力轮,包括轮子和轮子总成,轮子可转动地设置在轮子总成内部,轮子总成上设置有轮轴、承压片、调节开关、刹车柱、刹车块、限位块和氮气缸;刹车柱位于承压片内部,刹车块位于刹车柱底部;调节开关上下可滑动地设置在承压片底部;轮轴的中部设置有卡块,轮轴位于卡块下方的部分设置在刹车柱内,轮轴位于卡块上方的部分设置在承压片的上方;限位块、氮气缸设置于刹车柱远离调节开关的端部。本发明的优点在于:设计合理,用户能够在使用重力轮时有足够的时间来调整最佳位置直至完死锁死,而且能够实现重力轮和滑动轮的切换,操作方便,只需操作调节开关就可调节控制。
