Problems solved by technology

The above-mentioned brake pads rotate together with the brake wheels. When braking is required, the user needs to find the brake pads to brake with their feet. The above-mentioned implementation process is very difficult because it is difficult for the user to find the position of the brake pads when pushing the cart. , at the same time, in the process of releasing the brake, it is difficult for the user to accurately release the brake of the universal wheel in the braking state, and this process is often dangerous during use. Unnecessary danger easily occurs if you brake or release the brake

Abstract

The invention provides a traction braking universal wheel, belonging to the field of mobile equipment accessories, comprising a universal wheel body and a braking device. The universal wheel body includes a support leg and a wheel rotatably connected to the support leg, and the braking device includes The traction limit hole opened inside the support leg and the brake pad rotatably connected to the support leg, the traction limit hole is provided with a second traction rope, one end of the second traction rope protrudes from the upper part of the support leg, and the other end from the support The lower part of the leg extends out and is connected with the brake pad; the part where the second traction rope extends from the lower part of the support leg is sleeved with a spring, one end of the spring is pressed against the brake pad, and the other end is pressed against the support leg. The traction universal brake wheel adopts the structure that the brake pad is independent of the wheel, and the brake pad does not rotate with the wheel, which can save the user's time and effort in finding the brake pad, so as to realize the braking or release the brake quickly and timely, effectively avoiding unnecessary The danger occurs, making up for the shortcomings of the existing technology.

Description

technical field [0001] The invention relates to the field of mobile equipment accessories, in particular to traction braking universal wheels. Background technique [0002] The universal wheel is the so-called movable caster, and its structure allows horizontal 360-degree rotation. Existing universal wheels, especially foot brake type braking universal wheels, generally use simple brake pads to brake the universal wheels, so that the universal wheels can be braked and stopped. The above-mentioned brake pads rotate together with the brake wheels. When braking is required, the user needs to find the brake pads to brake with their feet. The above-mentioned implementation process is very difficult because it is difficult for the user to find the position of the brake pads when pushing the cart. , at the same time, in the process of releasing the brake, it is difficult for the user to accurately release the brake of the universal wheel in the braking state, and this process is o...
