The invention discloses a trundle brake device which comprises a fixing piece with a positioning hole, a rotating block, a pull rod, a linkage assembly and a trundle assembly. The rotating block is provided with a middle rotating hole, a first swing hole and a second swing hole, wherein the first swing hole and the second swing hole are formed in the two sides, and the middle rotating hole is rotatingly connected to the positioning hole; the bottom end of the pull rod is rotationally connected with the first swing hole; when the pull rod moves up and down, the rotating block can be driven to rotate with the middle rotating hole as the center, and therefore the position of the second swing hole in the left-right direction is changed; a linkage hole and a connecting plug are arranged at the two ends of the linkage assembly, the linkage hole is rotationally connected with the second swing hole, and the linkage assembly can be driven by the rotating block to move; the trundle assembly comprises a trundle body, and a brake hole is further formed in the side, right facing the linkage assembly, of the trundle body; and when the linkage assembly moves towards the trundle body, the connecting plug can be inserted into the brake hole, so that the trundle stops rotating. The trundle brake device is more reinforced in structure, rapid in action and long in service life.

    本发明公开了一种脚轮刹车装置,包括具有定位孔的固定件、转块、拉杆、联动组件和脚轮组件;转块具有中部转孔和两侧的第一摆动孔和第二摆动孔,中部转孔与定位孔转动连接;拉杆的底端与第一摆动孔转动连接;当拉杆上下活动时,能带动转块以中部转孔为中心转动,从而改变第二摆动孔左右方向上的位置;联动组件的两端为联动孔和插接头,联动孔与第二摆动孔转动连接,联动组件能在转动块的带动下移动;脚轮组件包括轮体,轮体在正对联动组件一侧上还开设有刹车孔;当联动组件向轮体移动时,插接头能够插入刹车孔中,使得脚轮停止转动。这种脚轮刹车装置的结构更加强化,动作迅速,使用寿命长。
