The invention discloses a brake device and discloses a cart with the brake device, and the brake device comprises a shell, a roller assembly, a driving assembly and a brake assembly. A rotating shaft penetrates through the center of the shell; the roller assembly comprises a hub, and a plurality of limiting holes are formed in the end face of the end, close to the shell, of the hub. The driving assembly comprises a rotatable driving part; the brake assembly comprises a movable limiting pin, the second end of the limiting pin is inserted into the limiting hole in a penetrating mode, the first end of the limiting pin can abut against the driving piece, the driving piece is driven to rotate to drive the first end of the limiting pin so that the second end of the limiting pin can be inserted into the limiting hole in a penetrating mode, and the limiting pin is used for locking or unlocking the hub. The driving piece is rotated, so that the second end of the limiting pin is inserted into the limiting hole in a penetrating mode, then rotation of the hub is limited through the limiting pin inserted into the hub, and finally the purpose of braking is achieved.

    本发明公开了一种刹车装置,并公开了具有刹车装置的推车,其中刹车装置包括外壳、滚轮组件、驱动组件以及刹车组件。外壳中心穿设有转轴;滚轮组件包括轮毂,轮毂的靠近外壳一端的端面上设置有若干限位孔;驱动组件包括可转动的驱动件;刹车组件包括可活动的限位销,限位销的第二端穿插于限位孔中,限位销的第一端可抵接于驱动件上,驱动驱动件转动以驱动限位销的第一端以使限位销的第二端穿插于限位孔中,限位销用于锁定或者解锁轮毂。转动驱动件,使得限位销的第二端穿插在限位孔中,进而通过插接在轮毂中的限位销限制住轮毂的转动,最终达到刹车的目的。
