A brake pad shaft, a brake pad, an inverted-T-shaped pin shaft, a transmission pin and an upper check ring are adopted; the inverted T-shaped pin shaft penetrates through the open hole; the transmission pin pulls up the inverted T-shaped pin shaft; the upper check ring prevents the inverted T-shaped pin shaft from falling off; one side of the brake pad is provided with a brake plate and is close to a roller, the other side is provided with a baffle and is connected with the inverted T-shaped pin shaft, and the brake pads are mounted on two sides of the bracket through the brake pad shaft; thebaffle is lifted along with the inverted T-shaped pin shaft; the brake plate rotates along the brake pad shaft to be attached to the roller, design can be added in the production process of the trundle, an existing trundle can be modified, an existing space and an existing structure are utilized, only a small number of spare and accessory parts are used, implementation is easy, pedaling is replaced with hand pulling, operation is convenient and fast, hands and eyes are consistent, safety and rapidness are achieved, braking can be achieved in movement, and safety and efficiency is high.

    本发明采用刹车片轴、刹车片、倒T型销轴、传动销、上部挡圈,倒T型销轴穿过开孔,传动销拉起倒T型销轴,上部挡圈阻止倒T型销轴下落,刹车片一边为刹车板,接近滚轮,一边为挡板,和倒T型销轴连接,通过刹车片轴安装于支架两侧,挡板随倒T型销轴上提,刹车板沿刹车片轴旋转贴住滚轮,既可以在脚轮的生产过程中添加设计,也可以对现有的脚轮进行改装,利用已有的空间和结构,仅用少量的零配件,实现简单,用手拉代替脚踩,操作便捷,手眼一致,安全快速,可以在运动中刹车,安全高效。
