Description

Technical Field

[0001] The utility model belongs to the technical field of wheels, in particular to a brake structure of a wheel. Background Art

[0002] The wheel is a tool that contacts the ground. For example, a cart generally has a wheel connected to the cart through a connecting frame and moves with the rolling of the wheel. In order to realize the function of stopping the cart anytime and anywhere, existing carts are equipped with a brake function, that is, the wheel is controlled by a brake parking device installed on the connecting frame through human control. The current control methods are basically tread brakes or side control locking wheel brakes. Both of these brakes will have unstable braking. For example, tread brakes rely on brake pads to press the tread to prevent it from rotating. If the cart is heavy and the cart is on a slope, the brake pads will slip on the tread. In addition, this direct pressing of the tread will easily damage the wheel. The side locking also has the problem of being unable to control the rotation of the wheel. Therefore, a structure that can better achieve braking by clamping the wheel with a brake pad is needed. Summary of the invention

For example, tread brakes rely on brake pads to press the tread to prevent it from rotating. If the cart is heavy and the cart is on a slope, the brake pads will slip on the tread, and this direct pressure on the tread will easily damage the wheel 2. Side locking also has the problem of being unable to control the rotation of the wheel 2. The utility model provides a slot 10 on the wheel 2, and the direction of the slot 10 is consistent with the direction of the spring sheet 9. When the spring sheet 9 on the brake assembly 5 is pressed down into the slot 10, the spring sheet 9 is against the slot 10 to restrict the wheel 2 from continuing to move, thereby achieving a braking effect.

The limiting portion 12 can effectively limit the spring sheet 9. Even if the wheel 2 may move slightly due to its weight in a sloped place, the spring sheet 9 is restricted by the limiting portion 12 and cannot escape from the slot 10, so the wheel 2 cannot move, and the braking is more stable. The length is longer than the spring sheet 9, which facilitates the spring sheet 9 to be pressed down and clamped into the slot 10.
