Abstract

An automatic brake control device for a cart comprises a supporting body supported by an axletree. A vertical cavity is arranged in the supporting body. A rotary roller body is arranged in the bottom of the cavity; the roller body is linked with wheels; the roller and central sleeves of the wheels pass through the axletrees; a plug pin capable of moving up and down is placed in a cavity of a supporting column on the roller body; the upper part of the plug pin is connected with a rope; and the left and the right sides of the roller body are respectively provided with a locking device stopping the roller body rotating and matching with the plug pin. The automatic brake control device for the cart is advantageous in that the as long as the cart moves without external forces either on a plane rod surface or a slope surface, the plug pin of the supporting column automatically moves downwardly and locks with a transmission disc, so the cart can be automatically stopped, thereby achieving safe usage; by the use of the automatic brake control device, labor force is saved; and the automatic brake control device for the cart cannot only be used on a baby cart, but can be applied to carts needing human care, like a wheelchair.
