DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1 As shown, a quick-detachable shock-absorbing wheel structure of a camping vehicle described in the utility model is arranged at the bottom of the frame of the camping vehicle, and comprises a mounting tube 1, a wheel frame 2, and a wheel rotatably arranged on the wheel frame 2. The mounting tube 1 is fixed on the frame, and a vertical wheel axle 3 is fixed on the wheel frame 2. The wheel axle 3 extends upward into the mounting tube 1 and rises and falls relative to the mounting tube 1. A shock-absorbing spring 4 is arranged between the wheel frame 2 and the mounting tube 1.

[0026] like Figure 2 As shown, a slideway is provided inside the mounting tube 1, and a sliding portion 6 is provided on the top of the wheel axle 3. The sliding portion 6 extends into the slideway and slides back and forth along the slideway. A locking mechanism is also provided on the mounting tube 1. The locking mechanism is used to lock the sliding portion 6 in the slideway or make the sliding portion 6 escape from the slideway. When the sliding portion 6 escapes from the slideway, the wheel axle 3 can be separated from the mounting tube 1.

[0027] like Figure 3 and Figure 5 As shown, the locking mechanism includes a button 5, which is movably arranged in the mounting tube 1 and can translate relative to the mounting tube 1. A limit block 7 is fixedly provided on the button 5, and a limit plate 8 is fixedly provided at the bottom of the limit block 7. The distance between the limit plate 8 and the button 5 forms the above-mentioned slideway. After the sliding part 6 passes over the limit plate 8 upward and enters the slideway, it can be blocked by the limit plate 8 to prevent the sliding part 6 from escaping from the slideway; pressing the button 5 pushes the limit plate 8 to translate, and the sliding part 6 is not blocked by the limit plate 8 when moving downward, so that the wheel axle 3 is separated from the mounting tube 1.

[0028] As Figure 4 and Figure 5 shown, a through hole 9 is provided on the installation pipe 1. One side of the button 5 is provided with a pressing portion 10. A return spring is provided inside the installation pipe 1 for pushing the pressing portion 10 out of the through hole 9. A guiding strip 11 is fixedly provided on the inner wall of the through hole 9. A guiding groove 12 corresponding to the position of the guiding strip 11 is provided on the button 5. The guiding strip 11 is embedded in the guiding groove 12, and the button 5 translates back and forth along the guiding strip 11.

[0029] A guiding inclined surface 13 is provided at the bottom of the limiting plate 8. As Figure 6 shown, a guiding conical surface 14 is provided at the top of the sliding portion 6. By pushing the sliding portion 6 to translate upward, the guiding conical surface 14 abuts against the guiding inclined surface 13, and the sliding portion 6 pushes the limiting plate 8 to squeeze the return spring into the slideway. A small-diameter section 15 is further provided on the wheel shaft 3. The sliding portion 6 is located at the top of the small-diameter section 15. An arc-shaped bayonet 16 is provided on the limiting plate 8. When the sliding portion 6 enters the slideway, the small-diameter section 15 is located in the arc-shaped bayonet 16. When the sliding portion 6 slides back and forth along the chute, the small-diameter section 15 translates synchronously relative to the arc-shaped bayonet 16.

[0030] A lining sleeve 17 is fixedly provided inside the installation pipe 1. The button 5 and the wheel shaft 3 are movably arranged on the lining sleeve 17. The cross-sectional shape of the wheel shaft 3 is square. A guiding hole 19 adapted to the cross-sectional shape of the wheel shaft 3 is provided on the lining sleeve 17. The wheel shaft 3 is inserted into the guiding hole 19 and slides back and forth along the guiding hole 19.

[0031] As Figure 2 shown, a shock-absorbing spring 4 is sleeved on the outer periphery of the wheel shaft 3. A sleeve 18 is fixedly provided on the wheel shaft 3. The top of the sleeve 18 is open. One end of the shock-absorbing spring 4 is located inside the sleeve 18, and the other end presses against the installation pipe 1.
