DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] Please refer to Figs. 1-3It is understood that this utility model provides a technical solution: a connecting and disassembling structure for a racing steering wheel, including: a steering wheel docking seat 1, a steering wheel body 2, and a steering wheel fixing seat 3. The top of the steering wheel docking seat 1 is connected to the steering wheel body 2, and the bottom of the steering wheel docking seat 1 is connected to the steering wheel fixing seat 3. A through groove 4 is provided inside the steering wheel docking seat 1, and a hemisphere 5 is slidably connected inside the through groove 4. A compression spring 6 is connected between the two hemispheres 5. A threaded knob 7 is threadedly connected inside the steering wheel docking seat 1 near the through groove 4. A limit plate 8 is connected to the end of the threaded knob 7. A docking rod 9 is welded to the outside of the steering wheel docking seat 1. A sliding groove 10 is provided inside the steering wheel fixing seat 3 near the docking rod 9. A retaining groove 11 is provided inside the steering wheel fixing seat 3 near the hemisphere 5. The docking rod 9 and the steering wheel fixing seat 3 form a sliding structure through the sliding groove 10. The steering wheel docking seat 1 and the steering wheel fixing seat 3 form an insertion structure.

[0020] In practical implementation, racing steering wheels are typically used by racing drivers. However, the connection and fixing speed of traditional racing steering wheels is relatively slow, making it difficult to quickly connect and fix them, resulting in low installation efficiency. The steering wheel docking seat 1 can be moved directly above the steering wheel fixing seat 3, while simultaneously aligning the docking rod 9 on the steering wheel docking seat 1 with the top of the slide groove 10. Then, the steering wheel docking seat 1 is pushed towards the steering wheel fixing seat 3. When the bottom of the steering wheel docking seat 1 moves into the steering wheel fixing seat 3, the arc-shaped surfaces of the two sets of hemispherical bodies 5 will be compressed by the steering wheel fixing seat 3, allowing the two sets of hemispherical bodies 5 to simultaneously compress the compression spring 6. When the compression spring... When compressed to its maximum extent, the two sets of hemispherical bodies 5 can move into the steering wheel docking seat 1, and at the same time, the docking rod 9 can slide along the slide groove 10 into the steering wheel fixing seat 3. When the bottom of the steering wheel docking seat 1 moves to the deepest part of the steering wheel fixing seat 3, the two sets of hemispherical bodies 5 are no longer squeezed by the steering wheel fixing seat 3, so that the two sets of hemispherical bodies 5 can be reset by the compression spring 6. When the two sets of hemispherical bodies 5 are reset, they can slide into the corresponding slots 11. At this time, the steering wheel docking seat 1 can be quickly connected to the steering wheel fixing seat 3, and the two sets of threaded knobs 7 can be rotated. When the threaded knobs 7 are rotated, the limiting plate 8 can be rotated.

[0021] See Figs. 1-3 It can be seen that when the two ends of the limiting plate 8 rotate to the side position of the hemisphere 5, the limiting plate 8 can limit the two sets of hemispheres 5, making it difficult for the two sets of hemispheres 5 to loosen. At the same time, the steering wheel docking seat 1 and the steering wheel body 2 are not easy to loosen. Through the above connection method, the steering wheel docking seat 1 and the steering wheel fixing seat 3 can be quickly connected and fixed, thereby improving the installation efficiency of the steering wheel body 2.

[0022] See Fig. 1 andFig. 2 The outer side of the steering wheel docking seat 1 is welded with a connecting block 12, the inside of the connecting block 12 is connected with a first connecting column 13, the end of the first connecting column 13 is welded with a first protrusion 14, the outer side of the steering wheel docking seat 1 is provided with a sleeving block 15, the bottom of the sleeving block 15 is connected with a sealing gasket 16, the top of the sleeving block 15 is connected with a second connecting column 17, the top of the second connecting column 17 is welded with a second protrusion 18, the inside of the sleeving block 15 close to the connecting block 12 is embedded with a magnetic block 19, and the sleeving block 15 and the steering wheel docking seat 1 form a sliding structure.

[0023] In specific implementation, during use of the racing car steering wheel, dust is easy to enter the connection between the steering wheel docking seat 1 and the steering wheel fixing seat 3, which is easy to cause abnormal sound between the steering wheel docking seat 1 and the steering wheel fixing seat 3. Before installing the steering wheel docking seat 1, the sleeving block 15 can be sleeved on the outer side of the steering wheel docking seat 1, and the sleeving block 15 can be pushed towards the connecting block 12. When the sleeving block 15 moves, the second connecting column 17 and the magnetic block 19 can move. When the second connecting column 17 and the second protrusion 18 move to the inside of the connecting block 12, the second protrusion 18 can be extruded on the surface of the first protrusion 14. Since the first connecting column 13 and the second connecting column 17 are both made of plastic material, the first connecting column 13 can bend the first protrusion 14 away from the second connecting column 17. When the first connecting column 13 is bent to a specified degree, the sleeving block 15 can be docked with the connecting block 12. At this time, the first connecting column 13 can reset the shape, so that the second protrusion 18 and the first protrusion 14 can be staggered and clamped, and the magnetic block 19 can be attracted to the bottom of the connecting block 12, so that the sleeving block 15 is not easy to loosen. The steering wheel docking seat 1 is docked with the steering wheel fixing seat 3, so that the sealing gasket 16 can be extruded on the top of the steering wheel fixing seat 3.

[0024] Referring to Fig. 1 and Fig. 2 It can be seen that the sealing gasket 16 can prevent dust from entering between the steering wheel docking seat 1 and the steering wheel fixing seat 3, so that abnormal sound is not easy to occur between the steering wheel docking seat 1 and the steering wheel fixing seat 3.

[0025] In summary, when the connecting and dismounting structure of the racing car steering wheel is used, the steering wheel docking seat 1 can be moved to the top of the steering wheel fixing seat 3, the docking rod 9 on the steering wheel docking seat 1 is aligned with the top of the sliding groove 10, and the steering wheel docking seat 1 is pushed towards the steering wheel fixing seat 3. Through the above connection mode, the steering wheel docking seat 1 and the steering wheel fixing seat 3 can be quickly connected and fixed, thereby improving the installation efficiency of the steering wheel main body 2. The sealing gasket 16 can prevent dust from entering between the steering wheel docking seat 1 and the steering wheel fixing seat 3, thereby preventing abnormal noise from being generated between the steering wheel docking seat 1 and the steering wheel fixing seat 3. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0026] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
