[0002] As a container for storing daily necessities, bags have become an essential tool for people's travel. They are loved and widely used. When traveling, movable bags have many significant advantages over immovable bags. Casters allow users to easily drag the bag on the ground without having to lift it by hand, greatly improving the convenience and comfort of travel.
[0003] For convenient carrying of bags, casters usually have a certain degree of flexibility and can easily achieve 360-degree rotation, allowing the bags to move flexibly in different directions. Some casters have rims on the casters to reduce noise, while others use silent wheels and have a braking function.
[0004] Existing luggage casters achieve noise reduction through wheel rims or silent wheels, but wheel rims are prone to loosening and falling off, and silent wheels are at risk of serious damage due to the weight of the luggage. The lack of shock absorption in casters can also reduce their lifespan. Therefore, a new type of luggage caster is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a new type of luggage caster, which aims to improve the problem of the lack of shock absorption function in existing new luggage casters, which leads to a reduced service life of the casters.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 This utility model provides an embodiment of a novel luggage caster, comprising a wheel housing 1, a rivet 3 fixedly connected to the inner wall of the wheel housing 1, a brake shock absorber bracket 2 fixedly connected to the outer wall of the rivet 3, a washer 4 provided at the top of the rivet 3, a shock absorber spring 7 fixedly connected to the surface of the brake shock absorber bracket 2, an insertion hole 6 provided on the surface of the brake shock absorber bracket 2, a pin 5 inserted into the inner wall of the insertion hole 6, a brake pin 8 provided inside the brake shock absorber bracket 2, a brake button 9 fixedly connected to the outer wall of the brake pin 8, an internal hexagonal nail 11 provided inside the brake shock absorber bracket 2, the internal hexagonal nail 11 penetrating the shaft core injection wheel assembly 100, and the shaft core injection wheel assembly 100 provided on the outer wall of the internal hexagonal nail 11.
[0034] Reference Figures 1-3The core injection wheel assembly 100 includes a nylon core 101. A toothed inner wheel 102 is snapped onto the outer wall of the nylon core 101. An outer casting wheel 103 is fixedly connected to the outer wall of the toothed inner wheel 102. The outer casting wheel 103 covers the outer wall of the toothed inner wheel 102. A sealing cap 104 is threaded onto the outer wall of the outer casting wheel 103. The sealing cap 104 is fitted onto the outer wall of the internal hexagonal nail 11. The sealing cap 104 can prevent dust and water, and protect the internal hexagonal nail 11. The injection material is a soft rubber material. The roller assembly achieves flexible contact with the ground, thereby reducing noise during rolling. Furthermore, since the roller assembly is injection molded, the roller will not loosen during use and is wear-resistant. The inner wheel has a brake gear. First, the nylon core 101 is passed through the toothed inner wheel 102, and then a ring of flexible soft rubber is injected on the outer ring to form the outer casting wheel 103. Since the toothed inner wheel 102 and the outer casting wheel 103 are integrally molded through injection, the brake assembly has stable performance, good braking performance, and is not easy to wear.
[0035] Reference Figures 4-5 The bottom of the brake damper bracket 2 is fixedly connected to a fixing ring 12. A threaded ring 13 is threadedly connected to the inner wall of the fixing ring 12. A support rod 14 is rotatably connected to the bottom of the threaded ring 13. The support rod 14 is L-shaped. Two sets of fixing rings 12, threaded rings 13, and support rods 14 are provided, and they are mirror images of each other about the central axis of the brake damper bracket 2, supporting the blade 16. A rotating shaft 15 is connected to the outer wall of the support rod 14. The outer wall of the rotating shaft 15 is fixedly connected to... A blade 16 is attached, and a magnetic sheet 19 is fixedly connected to the outer wall of the blade 16. A magnetic block 17 is magnetically connected to the magnetic sheet 19. An installation groove 18 is opened on the outer wall of the outer casting wheel 103. The outer wall of the magnetic block 17 is fixedly connected to the inner wall of the installation groove 18. Several installation grooves 18 and magnetic blocks 17 are provided. Several sets of installation grooves 18 and magnetic blocks 17 are installed in pairs on the outer wall of the opposite side of the two sets of shaft core injection wheel assemblies 100. The magnetic blocks 17 and magnetic sheets 19 are all waterproofed.
[0036] Working principle: The wheel housing 1 is connected to the bottom of the bag. Through the setting of the shock-absorbing spring 7, the bag and the caster have an elastic buffering and shock-absorbing function. The weight of the bag or external force will not directly act on the caster itself. At the same time, the axle core filling wheel assembly 100 is made of soft material and has a certain shock-absorbing function. When the axle core filling wheel assembly 100 rotates, several equally spaced magnetic blocks 17 will approach the corresponding magnetic pieces 19 on the blade 16 during the rotation. The magnetic pieces 19 are attracted by magnetic force and will drive the blade 16 to rotate accordingly, thereby cutting off the hair adhering to the bottom of the caster and preventing hair from accumulating at the bottom of the caster and causing entanglement as the caster rotates. Manually turning the threaded ring 13 will cause the two sets of threaded rings 13 to gradually unscrew from the fixed ring 12, allowing the blade 16 to be quickly disassembled for easy sharpening or replacement. This allows the caster to absorb shock while preventing hair from accumulating at the bottom and reducing the speed of the caster.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
