The invention discloses a trundle with a good braking effect, and belongs to the technical field of trundles, the trundle comprises a trundle seat, a wheel, a supporting shaft, a foot rest lever, a spring and a brake mechanism, the supporting shaft penetrates through the trundle seat and is fixedly connected to the trundle seat, the wheel is hinged to the supporting shaft, the foot rest lever is arranged on the foot rest lever, and the brake mechanism is arranged on the foot rest lever. The foot rest lever is hinged to the trundle seat, and the brake mechanism is fixedly connected to the end of the foot rest lever. When the foot rest lever is treaded, the brake plate and the brake block move towards the direction of the wheel under the action of the lever principle, the inclined surface on the brake block is gradually attached to the side surface of the wheel, so that the wheel is primarily and gently braked, the gear is firmly clamped by the rack, and the relative position of the brake plate and the support shaft is not changed; therefore, the position of the brake block is not changed, the brake block firmly abuts against the surface of the wheel, a good braking effect on the wheel is achieved, and the problem that the wheel cannot be rapidly braked in the dynamic operation process is solved.

    本发明公开了一种制动效果好的脚轮,属于脚轮技术领域,包括脚轮座、轮子、支撑轴、脚踏杆、弹簧和刹车机构,所述支撑轴穿过所述脚轮座,且所述支撑轴固定连接在所述脚轮座上,所述轮子铰接在所述支撑轴上,所述脚踏杆铰接在所述脚轮座上,所述刹车机构固定连接在所述脚踏杆的端部上;本发明通过踩踏脚踏杆时,由于杠杆原理的作用使制动板和制动块向轮子方向移动,刹车块上的斜面逐渐贴合轮子的侧面,实现对轮子的初步平缓制动,齿条牢牢地卡住齿轮,使得制动板和支撑轴的相对位置不产生变化,进而使制动块的位置不产生变化,制动块牢牢地抵住轮子的表面,对轮子具有良好的制动作用,解决了轮子无法在动态运行过程中快速制动的问题。
