Description

Technical Field

[0001] This utility model relates to the field of injection wheel technology, and more specifically, to an injection wheel structure. Background Technology

[0002] Injection-molded wheels are wheels formed by injecting molten plastic into a mold in a single process using high-pressure injection molding. Their core feature is a one-piece molded plastic wheel core, typically covered with a thin rubber tread to enhance shock absorption and quietness, with an embedded metal bushing supporting rotation. These wheels prioritize lightweight and low cost, offering better quietness than ordinary plastic wheels, but their wear resistance and load-bearing capacity are weaker than TPU wheels or dual-bearing swivel wheels. They are primarily suitable for everyday light-load travel and are a common feature in economy suitcases.

[0003] Some existing suitcases have external shock-absorbing structures, but these structures, located outside the injection molding wheel structure, take up a lot of space, reducing the suitcase's volume. Other injection molding wheels often lack a locking function, making the suitcase difficult to secure in a moving vehicle and prone to sliding, causing inconvenience. Some suitcases have locking mechanisms on the injection molding wheels, but locking them requires using your foot to crank the wheels, which is extremely inconvenient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an injection wheel structure to solve the problems existing in the prior art.

[0005] This utility model provides the following technical solution: a filling wheel structure, comprising:

[0006] Fixed casing;

[0007] The main connecting shaft is rotatably mounted inside the fixed housing.

[0008] The injection wheel body is fixedly installed at both ends of the main connecting shaft;

[0009] A shock-absorbing component, wherein the shock-absorbing component is disposed inside a fixed housing.

[0010] In some embodiments, the fixed housing includes a first part and a second part connected at an angle to the first part; the first part has a vertical first through hole, and the shock-absorbing component is disposed in the first through hole; the second part has a second through hole, and the main connecting shaft rotatably passes through the second through hole of the second part.

[0011] In some embodiments, the damping assembly includes a pad fixedly mounted inside a fixed housing, a buffer plate fixedly mounted on top of the pad, a sliding post fixedly mounted on top of the buffer plate, a top block slidably connected to the sliding post, the top block slidably mounted inside the fixed housing, and a second spring positioned between the bottom of the top block and the top of the buffer plate.

[0012] In some implementations, a disassembly assembly is also included, which is disposed on top of the shock-absorbing assembly.

[0013] In some embodiments, the disassembly assembly includes a wheel seat, the top of which is provided with a groove, a third spring is installed inside the groove, a retaining plate is slidably installed inside the groove, one end of the third spring is fixedly connected to one side of the retaining plate, the retaining plate has a gourd-shaped through hole, and the wheel seat has an insertion hole.

[0014] In some implementations, it also includes:

[0015] A braking assembly, wherein the braking assembly is disposed inside a fixed housing;

[0016] The brake assembly includes a button, with shafts fixedly mounted on both sides of the button. The shafts can engage with locking teeth on the injection wheel body to lock the button. A spring-loaded mechanism is fixedly mounted on the bottom of the button. Pressing the button can lock or unlock the injection wheel body.

[0017] In some embodiments, the spring-loaded mechanism includes a fixed frame and a connecting rod. The fixed frame is fixedly installed inside the fixed housing. A movable block is slidably installed inside the fixed frame. A connecting column is fixedly connected to the top of the movable block. A sliding hole is provided at the top of the fixed frame. The connecting column is slidably connected to the sliding hole at the top of the fixed frame.

[0018] In some embodiments, the top of the connecting column is fixedly connected to the bottom of the button, the bottom of the movable block is fixedly connected to a first spring, the bottom end of the first spring is fixedly connected to the inside of the fixed frame, the surface of the movable block is provided with an irregular groove, one end of the connecting rod is rotatably connected to one side of the fixed frame, and the other end of the connecting rod is fixedly installed with a sliding pin, which is slidably connected to the inside of the irregular groove.

[0019] In some embodiments, the top of the irregular groove includes at least a first inclined surface, a first vertex at the end of the first inclined surface, a second inclined surface below the first vertex, a second vertex at the end of the second inclined surface, a third inclined surface above the second vertex, a third vertex at the end of the third inclined surface, and a fourth inclined surface at the end of the third vertex.

[0020] In some embodiments, a cover is included, which is mounted on a fixed housing and is made of a transparent material.

[0021] This invention incorporates a shock-absorbing component. When the suitcase is subjected to bumps, the top block slides within the fixed outer shell, causing the sliding column to slide inwards. Simultaneously, the second spring is compressed and transmits the pressure to the buffer plate. After the buffer plate absorbs the pressure, the second spring rebounds, thus completing the shock absorption. Through this structure, the impact of bumps can be reduced, protecting the luggage inside the suitcase from damage, while also improving the quietness of the suitcase wheels and the stability of the suitcase.

[0022] The assembly includes a disassembly mechanism. The wheel hub connects to a fixing pin at the bottom of the suitcase via a connector. When fixed, the small hole of the gourd-shaped through-hole is locked into the bottom of the suitcase by the force of the third spring. By pulling the slider, the third spring retracts, causing the plate to slide inside the groove, aligning the large hole of the gourd-shaped through-hole with the fixing pin at the bottom of the suitcase. At this point, the entire inflatable wheel can be removed from the suitcase. This structure provides easy disassembly, facilitating wheel replacement for users, improving customer experience, increasing the reusability of the suitcase, and making it more environmentally friendly.

[0023] This application also includes a braking assembly. When the button is pressed, the button moves downwards, causing the movable block to slide downwards inside the fixed frame via the connecting column. At this time, the first spring is compressed and contracts, and the sliding pin slides inside the irregular groove until it slides into the slot at the top of the irregular groove. At this point, the button is fixed, and the shaft is locked in the locking teeth, making the injection wheel body fixed and stable. Through the above structure, the injection wheel body has a braking and locking function, which can fix the luggage on which the injection wheel body is installed to a stable position, making it convenient for use in a moving vehicle. The injection wheel body can be locked and unlocked simply by pressing the button, making it easy to operate. Attached Figure Description

[0051] Example 1

[0052] Figures 1 to 5 This is a pouring wheel structure according to Embodiment 1 of the present invention, including a fixed outer shell 1. Figure 2-3 As shown, the fixed housing 1 includes a first part 11 extending vertically and a second part 12 connected at an angle to the first part; the first part 11 has a vertical first through hole 13 inside; the bottom of the second part 12 has a second through hole 14 perpendicular to the first through hole 13; a main connecting shaft 2 rotatably passes through the second through hole 14 of the second part 12; and injection wheel bodies 3 are fixedly installed at both ends of the main connecting shaft 2, so that the two injection wheel bodies 3 are located on both sides of the fixed housing 1. The injection wheel can be a TPU injection wheel.

[0053] In this embodiment, a shock-absorbing component 5 is provided, which is disposed in the first through hole 13 of the first part 11.

[0054] like Figure 3 As shown, the shock-absorbing component 5 includes a pad 51, which is installed inside the fixed housing 1, for example, snapped into the bottom of the first through hole 13. A buffer plate 52 is fixedly installed on the top of the pad 51, and a sliding post 53 is fixedly installed on the top of the buffer plate 52. A top block 54 is slidably connected to the sliding post 53, and the top block 54 is slidably installed inside the fixed housing 1. A second spring 55 is positioned between the bottom of the top block 54 and the top of the buffer plate 52. In some embodiments, a cover 56 is provided on the first part 11 corresponding to the position of the shock-absorbing component 5. The cover 56 facilitates observation of whether the shock-absorbing component is working properly and also facilitates maintenance of the shock-absorbing component 5.

[0055] When the suitcase is bumped, the top block 54 will slide in the fixed outer shell 1, causing the sliding column 53 to slide into the top block 54. At the same time, the second spring 55 is compressed and the pressure is transmitted to the buffer plate 52. After the buffer plate 52 absorbs the pressure, the second spring 55 rebounds, thus completing the shock absorption.

[0056] In some implementations, such as Figure 4 , Figure 5 As shown, it also includes a disassembly component 6, which is disposed on top of the shock-absorbing component 5 and is detachably connected to the top of the shock-absorbing component 5.

[0057] like Figure 4 , Figure 5 As shown, the disassembly assembly 6 includes a wheel base 61. A groove 63 is provided on the top of the wheel base 61. A third spring 64 is installed inside the groove 63. A retaining plate 65 is slidably installed inside the groove 63. One end of the third spring 64 is fixedly connected to one side of the retaining plate 65. A gourd-shaped through hole 66 is provided on the retaining plate 65, and an insertion hole 67 is provided on the wheel base 61. A slider 62 is slidably installed on the bottom of the wheel base 61. The retaining plate 65 is connected to the slider 62, and the slider 62 controls the movement of the retaining plate 65 within the groove 63.

[0058] In some implementations, such as Figure 11 As shown, it may also include a ball bearing 7, which is installed inside the body 3 of the filling wheel, improving the smoothness of the wheel and making the shaft more wear-resistant and durable.

[0059] The cover 56 is made of transparent material, allowing the internal shock-absorbing components 5 to be seen.

[0060] In this embodiment, when the injection wheel structure is in use, the wheel seat 61 is connected to the fixing pin at the bottom of the suitcase through the insertion hole 67. In the fixed state, under the elastic force of the third spring 64, the small hole of the gourd-shaped through hole 66 of the locking plate 65 will lock the fixing pin at the bottom of the suitcase. By pulling the slider 62, the third spring 64 will retract and the locking plate 65 will slide inside the slide groove 63, so that the large hole of the gourd-shaped through hole 66 is aligned with the fixing pin at the bottom of the suitcase. At this time, the entire injection wheel can be removed from the suitcase.

[0061] Example 2

[0062] Figures 6 to 10 Embodiment two of this utility model is shown. For example... Figure 6 , Figure 10 As shown, this embodiment also includes a brake assembly 4. The top of the second part 12 of the fixed housing 1 is lower than the top of the first part 11. The top of the first part 11 is provided with a third through hole 15, which forms a receiving space in the second part 12. The receiving space has strip grooves 16 on both sides. The brake assembly 4 is disposed inside the fixed housing 1. Preferably, the brake assembly 4 is disposed in the third through hole 15.

[0063] like Figure 7 As shown, the brake assembly 4 includes a button 41, with a transverse shaft 42 fixedly mounted on both sides of the button 41. The transverse shaft 42 can slide in the strip groove 16, and a spring-loaded mechanism 43 is fixedly mounted on the bottom of the button 41. Figure 8 As shown, the inner side of the TPU injection wheel body 3 is provided with a retaining tooth 44.

[0064] like Figure 9 As shown, the spring-loaded mechanism 43 includes a fixed frame 431 and a connecting rod 436. The fixed frame 431 is fixedly installed inside the third through hole 15. A movable block 432 is slidably installed inside the fixed frame 431. A connecting post 433 is fixedly connected to the top of the movable block 432. The top of the fixed frame 431 has a sliding hole. The connecting post 433 passes through the sliding hole at the top of the fixed frame 431 and is slidably connected to the fixed frame 431. The top of the connecting post 433 is fixedly connected to the bottom of the button 41. A first spring 434 is fixedly connected to the bottom of the movable block 432. The bottom end of the first spring 434 is fixedly connected to the inside of the fixed frame 431. A shaped groove 435 is formed on the surface of the movable block 432. One end of the connecting rod 436 is rotatably connected to one side of the fixed frame 431. A sliding pin 437 is fixedly installed at the other end of the connecting rod 436.

[0065] In this embodiment, when the button 41 is pressed, the button 41 moves downward, causing the movable block 432 to slide downward inside the fixed frame 431 via the connecting column 433. At this time, the first spring 434 is compressed and contracted, while the sliding pin 437 slides inside the irregular groove 435 until it slides into the slot at the top of the irregular groove 435. At this time, the button 41 is fixed, and the shaft 42 is locked in the locking tooth 44, making the TPU injection roller body 3 fixed and stable. Specifically, the sliding pin 437 slides inside the irregular groove 435 as follows: during the pressing of the button 41, the first inclined surface 71 presses against the sliding pin 437, and the sliding pin 437 moves along the first inclined surface 71 to the first vertex 72. After the button 41 is no longer pressed, the button 41 is released. Under the action of the first spring 434, the sliding pin 437 is pressed by the second inclined surface 73 and reaches the second vertex 74. At this time, the movable block 432 is fixed, and the shaft 42 is locked in the locking tooth 44.

[0066] When locking is not required, press button 41. The sliding pin 437 is pressed by the third inclined surface 75 and moves along the third inclined surface 75 to the third apex 76. Then release button 41. Under the action of the fourth inclined surface 77, the sliding pin 437 slides along the irregular groove 435 to the bottom. At this point, the locking of the TPU injection wheel is released.

[0067] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
