Problems solved by technology

However, this device fails to change the fact that the narrow part of the eccentric wheel is subject to a relatively large pulling force, and the place where the force is applied is relatively close to the rotating shaft during the rotation, which is not labor-saving enough, so the structure of the device needs to be further improved

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 to Figure 12As shown, the brake pulling device used on the cart in this embodiment includes a pressing part installed on the push rod 1 of the cart, and a pull cord 2 for controlling the braking of the cart is arranged in the pressing part, and the pressing part It includes a pressing block 3 and an eccentric wheel 4 arranged vertically and eccentrically rotatable. The eccentric wheel 4 is arranged in the inner cavity of the push rod 1 through an eccentric shaft 41. The two ends of the eccentric shaft 41 are connected to the push rod The corresponding side surfaces on both sides of the rod 1 are fixed, and the pressing block 3 can be inserted into the inner cavity of the push rod 1 so as to move up and down. The concave cavity 32 that the wheel 4 extends into, the eccentric wheel 4 stretches into the concave cavity 32 of...

Abstract

A brake pulling device for a cart, comprising a pressing part installed on a push rod (1) of the cart, a pull rope (2) is arranged in the pressing part, and the pressing part includes a pressing block (3), an eccentric wheel (4 ), the eccentric wheel (4) is arranged in the inner cavity of the push rod (1) through the eccentric shaft (41), and the two ends of the eccentric shaft (41) are fixed with the corresponding sides of the push rod (1), and the pressing The block (3) is located in the inner cavity of the push rod (1), the pressing block (3) is vertically provided with a bar-shaped cavity (31), the lower part of the pressing block (3) is provided with a concave cavity (32), and the eccentric wheel (4 ) into the concave cavity (32) and is movably connected with the pressing block (3), the eccentric shaft (41) of the eccentric wheel (4) is located at the bar-shaped cavity (31) position of the pressing block (3), and the pull cord ( 2) Go around the bottom surface of the eccentric wheel (4) and pass through the buckle hole (43) of the eccentric wheel (4) to be fixed with the end face of the buckle hole (43), and a locking mechanism is provided on the pressing block (3) . The invention has the advantages of labor-saving and convenient operation, firm and compact structure and long service life.

Description

technical field [0001] The invention relates to the technical field of brake device manufacturing, in particular to a brake pull device used on a trolley. Background technique [0002] A Chinese utility model patent with the patent number CN200520097983.1 titled "Brake Device for Luggage Carts" discloses a brake device for luggage carts. device, the other end of the brake line is connected to the eccentric wheel, and the brake line is drawn out behind the eccentric wheel. Because the utility model uses the brake line to surround the eccentric wheel and lead out, it changes the stress structure and direction of the eccentric wheel, and then solves the problem that the eccentric wheel is not easy to break. However, this device fails to change the fact that the narrow part of the eccentric wheel is subjected to a relatively large pulling force, and the place where the force is applied is relatively close to the rotating shaft during the rotation, which is not labor-saving enou...
