Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, and specifically relates to a luggage shock-absorbing wheel. Background Technology

[0002] Suitcases are practical tools used to pack luggage when traveling. They are usually made of hard or soft materials and are characterized by wear resistance and water resistance. Common types include rolling suitcases, carry-on suitcases, and checked suitcases. They come in various sizes and capacities to suit different travel needs. The design focuses on portability and is generally equipped with a pull rod, wheels, and combination lock for easy movement and security.

[0003] Traditional suitcases generally use fixed rollers, which lack effective shock absorption. When the suitcase moves on bumpy roads, vibration and impact are directly transmitted to the suitcase, which can easily damage the items inside. To solve the above problems, we provide a suitcase shock-absorbing wheel. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-absorbing wheel for a suitcase, in order to solve the problem mentioned in the background art that traditional suitcases generally adopt a fixed roller structure, which lacks effective shock absorption function. When the suitcase moves on a bumpy road, the vibration and impact will be directly transmitted to the suitcase body, which can easily cause damage to the items inside the suitcase.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a luggage shock-absorbing wheel, including the wheel assembly, the wheel assembly including an inner ring and an outer ring, a plurality of elastic plates are fixedly connected to the outer side of the inner ring in a circular array, the other end of the elastic plates is fixedly connected to the outer ring, a tire is fitted onto the surface of the outer ring, and a plurality of protrusions are fixedly connected to the surface of the outer ring.

[0006] Preferably, the elastic plate includes a first arc-shaped segment, one end of which is fixedly connected to the inner ring, the other end of which is fixedly connected to a second arc-shaped segment, the other end of which is fixedly connected to a third arc-shaped segment, and the other end of which is fixedly connected to the outer ring. The arc angle between the first and second arc-shaped segments is 85°-95°, and the arc angle of the third arc-shaped segment is 130°-145°.

[0007] Preferably, the inner ring has two bearings fitted inside, the bearings have axles fitted inside, the axles have legs fixedly fitted onto their surfaces, and both ends of the axles are threaded with fixing nuts.

[0008] Preferably, the top of the support leg is rotatably connected to a mounting base, and the top of the mounting base is integrally machined with several mounting holes.

[0009] This utility model has the following beneficial effects: When encountering bumpy roads during movement, the tires apply pressure to the elastic plate through the outer ring, compressing it. The elastic plate then returns to its original position to absorb vibration energy, significantly reducing the impact on the suitcase and effectively improving shock absorption performance. At the same time, the device has a simple and compact design, achieving efficient shock absorption without complex structures. This reduces manufacturing costs and improves the reliability and durability of the device, ensuring the suitcase remains stable during movement and reducing the risk of damage to items inside due to vibration. Overall, the device is significantly more practical than traditional fixed suitcase wheel structures. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Example 1:

[0014] refer to Figure 1-4 A luggage shock-absorbing wheel includes a wheel assembly 3, which includes an inner ring 31 and an outer ring 32. A plurality of elastic plates 33 are fixedly connected to the outer circular array of the inner ring 31. The other end of the elastic plates 33 is fixedly connected to the outer ring 32. A tire 34 is fitted onto the surface of the outer ring 32. A plurality of protrusions 35 are fixedly connected to the surface of the outer ring 32. Preferably, the protrusions 35 are provided to increase the tighter connection between the outer ring 32 and the tire 34. The tire 34 is made of soft rubber, which is intended to increase the friction between the tire 34 and the ground and to achieve a noise reduction effect.

[0015] Specifically, when the device encounters bumpy roads during movement, the tire 34 can apply pressure to the elastic plate 33 through the outer ring 32 and compress it. Subsequently, the elastic plate 33 returns to its original position to absorb vibration energy, thereby significantly reducing the impact on the suitcase and effectively improving shock absorption performance. At the same time, the device has a simple and compact design, which can achieve efficient shock absorption without complex transmission mechanisms. This reduces manufacturing costs and improves the reliability and durability of the device, ensuring that the suitcase remains stable during movement and reducing the risk of damage to the contents of the suitcase due to vibration. The overall practicality of this device is significantly better than that of traditional fixed suitcase wheel structures.

[0016] refer to Figure 4 The elastic plate 33 includes a first arc-shaped segment 331. One end of the first arc-shaped segment 331 is fixedly connected to the inner ring 31. The other end of the first arc-shaped segment 331 is fixedly connected to a second arc-shaped segment 332. The other end of the second arc-shaped segment 332 is fixedly connected to a third arc-shaped segment 333. The other end of the third arc-shaped segment 333 is fixedly connected to the outer ring 32. The arc angle between the first arc-shaped segment 331 and the second arc-shaped segment 332 is 85°-95°, and the arc angle between the third arc-shaped segment 333 is 130°-145°. By setting the first arc-shaped segment 331, the second arc-shaped segment 332 and the third arc-shaped segment 333, the shock absorption stroke of the device can be effectively improved.

[0017] refer to Figure 1 The inner ring 31 has two bearings 6 inside, and the bearings 6 have a wheel axle 4 inside. The surface of the wheel axle 4 is fixedly fitted with a support leg 2. Both ends of the wheel axle 4 are threaded with fixing nuts 5. The fixing nuts 5 can effectively limit the two ends of the wheel axle 4 and prevent the wheel assembly 3 from disengaging from the wheel axle 4. By setting the bearings 6, the wheel assembly 3 and the wheel axle 4 can rotate smoothly.

[0018] refer to Figure 1 The top of the support leg 2 is rotatably connected to the mounting base 1. The top of the mounting base 1 is integrally machined with several mounting holes 7. By setting the mounting base 1 and the mounting holes 7, it is easy to install it with the suitcase body.

[0019] Brief description of the usage process: The device is installed on the housing via the mounting base 1. When the housing is moved, the wheel assembly 3 rotates. When passing over bumpy roads, the tire 34 compresses and resets the elastic plate 33 through the outer ring 32, thereby effectively playing a shock absorption role.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
