Active braking device for trolley

Abstract

The invention discloses an active braking device for a trolley. The active braking device comprises a brake shaft installing base, a brake cable, a shifting rod and fixing bases; the brake shaft installing base is arranged on one side of a fixing frame of a corresponding wheel, the fixing bases are arranged on a pushing rod, the shifting rod is hinged to the fixing bases, the side face of the wheel is provided with a circle of spaced protrusions or grooves, a brake shaft with the tail end pointing to the gaps between the adjacent protrusions or the grooves is arranged in the brake shaft installing base, the brake cable is connected between the front end of the brake shaft and the bottom of the shifting rod, and a spring driving the brake shaft to extend into the gaps between the adjacent protrusions or the grooves is arranged in the brake shaft installing base. In this way, the active braking device for the trolley has the advantages that in the stopping process, the shifting rod losesthe constraint from the hands of a user, the spring resets with compression force, the tail end of the brake shaft moves into the gaps between the adjacent protrusions or the grooves to prevent the wheel from rotating, the trolley is stopped once the user loosens his or her grip, and active braking with fast response is achieved.

Description

technical field [0001] The invention relates to the field of logistics tools, in particular to an active braking device for a cart. Background technique [0002] In order to improve the stability of the cart, some carts have their own brakes on the wheels, which can be stepped on to trigger the brakes and brake to avoid the rotation of the wheels. [0003] Existing trolley braking devices are usually passive braking devices that need to be triggered manually without an active braking system. If the operator forgets to perform the braking operation when parking, the wheels are prone to self-rotation when encountering slopes or vibrations, resulting in accidents and poor safety. . Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide an active braking device for a pushcart, which performs active braking when parking and improves the safety of use. [0005] In order to solve the above technical problems, a technica...
