Abstract
The invention relates to a trundle with a brake. The trundle with the brake comprises a connecting base, a supporting frame and an idler wheel, wherein the supporting frame is connected to the position below the connection base in a rotatable mode through a first rotating shaft which is vertically arranged, and the idler wheel is connected to the supporting frame in a rotatable mode through a second rotating shaft which is arranged in the horizontal direction. A brake mechanism which restrains the idler wheel from rotating is arranged on the supporting frame. The brake mechanism comprises a brake pad and a pedal, wherein the brake pad is connected to the supporting frame in a rotatable mode and is elastic, and the pedal is connected to the supporting frame in a rotatable mode and abuts against the brake pad. The brake mechanism has the release state and the brake state. When the brake mechanism is in the release state, the brake pad is separated from the idler wheel. When the brake mechanism is in the brake state, the brake pad abuts against the idler wheel. A first limiting mechanism is used for restraining the pedal to rotate downwards relative to the brake pad when the brake mechanism is in the brake state is arranged between the brake pad and the pedal. According to the trundle with the brake, the brake mechanism is novel and simple.
