[0003] The wheels of existing carts are generally installed vertically on the cart's legs. They are subjected to greater pressure from the cargo, which requires the operator to exert greater thrust when using the cart. However, the current wheels only rely on a simple single brake pad, and the wheels can easily break free from the brake pad when braking. In this case, the safety performance of the entire cart is not high.

[0004] In addition, the wheels of existing carts cannot be fixed in a certain direction, which causes a lot of inconvenience when used. Summary of the Invention

[0029] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0030] As attached Figure 1-6 The figure shows a wheel assembly with a fixed brake, mounted on a wheel 9. The wheel 9 is mounted on a brake bracket 4 via a second rotating shaft. The brake bracket 4 is mounted on one end of a first rotating shaft 2, the other end of which is fixedly connected to a brake disc 5. An outer bearing housing 5 and an inner bearing housing are mounted on the top of the first rotating shaft 2. In this embodiment, a top plate 1 is provided on the brake bracket 4 for mounting the wheel assembly on the cart body. A dual brake mechanism is mounted on the brake bracket 4.

[0031] The dual braking mechanism includes a first pedal 7 hinged to the brake bracket 4, a second pedal 8 hinged to the first pedal 7, and a brake pad 6 hinged to the second pedal 8. A brake assembly is provided at one end of the brake pad 6 corresponding to the wheel 9, and a fixed assembly is provided at one end of the brake pad 6 corresponding to the brake disc 5.

[0032] A first pedal 7 and a second pedal 8 are installed on the brake bracket 4, one end of the first pedal 7 is hinged to the brake bracket 4, the other end of the first pedal 7 is connected to the hinge point at one end of the second pedal 8 through a third rotating shaft, and the hinge point at the other end of the second pedal 8 is connected to the second rotating seat 6-2 of the brake pad 6 through a fourth rotating shaft.

[0033] The brake pad 6 includes a first rotating seat 6-1 hinged on the brake bracket 4, and a second rotating seat 6-2 hinged on the lower part of the second pedal. The first rotating seat 6-1 is provided with a fifth rotating shaft, and the second rotating seat 6-2 is provided with a fourth rotating shaft.

[0034] The end of the brake pad 6 corresponding to the wheel 9 is equipped with a brake assembly. The brake assembly includes one or two auxiliary brake pads 6-3 mounted on the end of the brake pad corresponding to the wheel 9. The auxiliary brake pads 6-3 are used to reversely lock the wheel to ensure effective braking. The end of the brake pad 6 corresponding to the first rotating seat 6-1 is bent to form an elastic member 6-5, which assists in rebounding during the braking process.

[0035] One end of the brake pad 6 corresponding to the brake disc 5 is provided with a fixed assembly, and the fixed assembly includes a pair or two pairs of positioning clips 6 - 4 formed by protrusions provided on one end of the brake pad 6 corresponding to the brake disc 5 .

[0036] A plurality of positioning slots 5-1 are evenly arranged on the edge of the brake disc 5, and the positioning clips 6-4 match the positioning slots 5-1 on the brake disc 5. The positioning clips 6-4 are inserted into the positioning slots 5-1 on the brake disc 5 to lock the direction of the brake disc. When braking, the direction of the wheel 9 remains fixed.

[0037] When the cart needs to stop, the first pedal 7 is stepped on, and the second pedal 8 is raised under the drive of the first pedal 7. At this time, the first pedal 7 and the second pedal 8 are in a parallel state. At this time, the auxiliary brake pad 6-3 at one end of the brake pad 6 rubs against the wheel 9 to prevent the wheel 9 from rotating to achieve braking. At the same time, the positioning clamp 6-4 at the other end of the brake pad 6 is inserted into the positioning clamping groove 5-1 on the brake disc 5, and the brake disc 5 is locked and cannot be rotated. The direction of the first rotating shaft 2 fixedly connected to the brake disc 5 is locked and cannot be rotated. Because the top end of the first rotating shaft 2 is provided with a brake bracket 4, the brake bracket 4 is connected to the wheel through a bearing. Since the direction of the first rotating shaft 2 is locked and cannot be rotated, the brake direction of the wheel 9 is locked and cannot be rotated. At this time, the brake is braked and the direction is fixed. The first pedal 7 and the second pedal 8 are in a parallel state. At this time, when the second pedal 8 is stepped on, the first pedal 7 is lifted up, and the positioning card 6-4 at the other end of the brake pad 5 falls off from the positioning slot 5-1 of the brake disc, and the auxiliary brake pad 6-3 at the other end leaves the wheel 9, realizing the release of the brake, the wheel rotates normally, and the cart can continue to move.

[0038] The technology of the present application can be used not only in carts, but also in carts with universal wheels.

[0039] The utility model can be used to brake after the wheel stops. In addition, when braking, the direction can be determined before braking by stepping on the brake-releasing wheel. This solves the problem that the existing brake pads can only be pressed down to brake but cannot be pressed down to contact the brake. The utility model is easy to use and can adapt to use in various environments.

[0040] The linkage design of the first pedal and the second pedal simplifies the braking and releasing operation process. The user only needs to step on the first pedal to brake and step on the second pedal to release the brake. The operation is simple and quick.
