[0002] The brake wheels on traditional luggage do not have a braking function. When the luggage is not moving, if you do not hold the luggage with your hands, the luggage may slide on its own, which is inconvenient to use and has safety hazards.

[0003] In order to solve the above technical problems, many manufacturers have designed luggage brake wheels with brake devices. The existing luggage brake wheel assembly with brakes has a structural design that requires the clamping position to be properly aligned to press the clamping parts. Excessive force can easily break it, and when the brake pads are not working, the vibration caused by walking can easily cause the brake assembly to slip and get stuck on the brake wheel, resulting in poor brake reliability and inconvenience in use. The structure is complex and the installation is inconvenient. When the parts are damaged, the damaged parts cannot be replaced and the entire wheel can only be replaced, resulting in waste of resources, poor brake reliability, and the brake effect weakened or disappeared due to long-term use.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 8 As shown, a luggage wheel set with a braking function includes a wheel seat 1, a brake wheel 3 and a bracket 2 for supporting the brake wheel 3, wherein the interior of the bracket 2 is respectively provided with a guide groove 22 for installing a brake switch 4 and a matching groove 21 for installing a brake pad 5, the brake switch 4 is slidably inserted into the inner wall of the guide groove 22, the brake pad 5 is slidably inserted into the matching groove 21, the two brake wheels 3 are mounted on both sides of the bracket 2 through the sleeve connection of a pin shaft 33 to realize rotation, and the inner surfaces of the two brake wheels 3 are fixedly connected with a locking gear 34 that matches the brake pad 5 to lock or release the brake wheel 3.

[0027] Furthermore, in order to limit the brake switch 4 in two states, the brake switch 4 includes a push plate 41 with an arc-shaped structure, a guide protrusion 43 and a limit groove 42, and the guide protrusion 43 and the limit groove 42 are respectively arranged on both sides of the brake switch 4.

[0028] Furthermore, the protruding end of the guide protrusion 43 is located in the locking groove 221 to slide up and down, and the locking groove 221 is provided on a side of the inner wall of the guide groove 22 close to the bracket 2 .

[0029] Furthermore, a limiting block 51 meshing with the locking gear 34 is provided on the inner side of the brake pad 5 , and a limiting tooth 52 is provided on the middle part of the outer side wall of the brake pad 5 .

[0030] Furthermore, a groove 53 is provided on the middle surface of the inner wall of the brake pad 5 , and a positioning block 23 is provided on the inner wall of the matching groove 21 .

[0031] Furthermore, a spring 6 is sleeved on the outer surface of the positioning block 23 , and a free end of the spring 6 is movably sleeved on the inner wall of the groove 53 of the brake pad 5 .

[0032] Furthermore, a clamping plate 54 is provided on the upper side of the brake pad 5, and a limiting step 24 is provided on the upper part of the matching groove 21 and on the inner wall of the bracket 2; when the brake switch 4 is in a released state, the clamping plate 54 abuts against the limiting step 24 to limit the brake pad 5.

[0033] Furthermore, the brake wheel 3 includes a wheel cover 31 and a wheel hub 32 , and a locking gear 34 is disposed on the inner surface of the wheel hub 32 .

[0034] Working principle: When the brake wheel 3 needs to be locked, the user presses one end of the pressing plate 41 of the brake switch 4 downward, so that the brake switch 4 slidably plugged into the inner wall of the guide groove 22 slides downward, so that the limiting tooth 52 that is limited against the limiting groove 42 of the brake switch 4 slides toward the positioning block 23 and finally abuts against the highest point of the side wall of the brake switch 4, so that the brake pad 5 also slides toward the positioning block 23 and squeezes the spring 6. At this time, the limiting block 51 of the brake pad 5 meshes with the locking gear 34 of the brake wheel 3, thereby locking the brake wheel 3;

[0035] When the brake wheel 3 needs to roll flexibly, the user lifts one end of the push plate 41 of the brake switch 4 upwards, so that the brake switch 4 slidably inserted in the inner wall of the guide groove 22 slides upwards, and when the raised end of the guide protrusion 43 of the brake switch 4 slides to the top of the locking groove 221, the brake switch 4 stops sliding to prevent the brake switch 4 from falling off from the guide groove 22 when lifted. At this time, the spring 6 resets and pushes the limiting tooth 52 of the brake pad 4 against the limiting groove 42 of the brake switch 4, so that the limiting block 51 of the brake pad 5 is disengaged from the locking gear 34 of the brake wheel 3, and the limiting tooth 52 is locked in the limiting groove 42 to limit the brake switch 4. The locking gear 34 loses the limit of the limiting block 51 of the brake pad 5 and can rotate flexibly.
