[0024] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Figure 1 An embodiment of the utility model provides a wheel device with a quick-release structure, including: a frame 10, a mounting seat 20 and a wheel 30.

[0025] The bottom of the frame 10 is provided with a mounting groove 11, and a limiting step 12 is provided in the mounting groove 11; a marble 211 limiting mechanism 21 is provided on the mounting seat 20, and a portion of the mounting seat 20 extends into the mounting groove 11 and rotates with the mounting groove 11, so as to facilitate the adjustment of the direction of the wheel 30. The marble 211 limiting mechanism 21 abuts against the limiting step 12, so that the mounting seat 20 cannot be separated from the mounting groove 11, and the mounting seat 20 is installed. When the marble 211 limiting mechanism 21 is separated from the limiting step 12, the mounting seat 20 can be taken out of the mounting groove 11, and the mounting seat 20 can be disassembled; the wheel 30 is arranged at the bottom of the mounting seat 20.

[0026] The structure of the marble 211 limiting mechanism 21 can be selected according to actual needs. In some optional embodiments, the marble 211 limiting mechanism 21 includes a plurality of marbles 211, a button 212 and a movable rod 213. The mounting seat 20 is provided with a movable channel 22, and the movable channel 22 is provided with a plurality of through holes 221 connected to the outer side surface of the mounting seat 20. The marble 211 is slidably arranged in the through hole 221, and a portion of the marble 211 extends out of the through hole 221 and abuts against the limiting step 12. The movable rod 213 is movably arranged in the movable channel 22, and the movable rod 213 is provided with an abutting portion. 214, the abutment portion 214 abuts against the marble 211, the button 212 is connected to the movable rod 213 and extends from the bottom of the movable channel. When the button 212 moves toward the movable channel 22, the button 212 drives the movable rod 213 to move so that the abutment portion 214 is separated from the marble 211, so that the marble 211 can move into the through hole 221 and separate from the limiting step 12, thereby releasing the restriction on the mounting seat 20. It should be noted that at this time, the other parts of the movable rod 213 can limit the position of the marble 211, so that the marble 211 cannot completely enter the movable channel 22 and completely separate from the through hole 221. When the mounting seat 20 is installed, the button 212 returns to its original position, and the abutment portion 214 pushes the marble 211 back until part of the marble 211 extends out of the through hole 221, so that the marble 211 can abut against the limiting step 12, and the position of the mounting seat 20 is re-restricted.

[0027] In some optional embodiments, the marble 211 limiting mechanism 21 also includes a reset elastic member 215, which is disposed in the active channel 22 and is respectively connected to the button 212 and the active channel 22. After the user presses the button 212 into the active channel 22, the reset elastic member 215 undergoes elastic deformation. When the user releases the button 212, the reset elastic member 215 resets the button 212.

[0028] In some optional embodiments, a mounting post 23 is provided on the mounting seat 20 , a movable channel 22 is provided in the mounting post 23 , and the mounting post 23 is rotatably matched with the mounting groove 11 , thereby facilitating the mounting seat 20 to rotatably match with the mounting groove 11 .

[0029] In some optional embodiments, a plurality of through holes 221 are provided in the active channel 22, and the plurality of through holes 221 are evenly arranged around the active channel 22. The marble 211 limiting mechanism 21 includes a plurality of marbles 211, and the marbles 211 are correspondingly arranged in the through holes 221. The plurality of marbles 211 can improve the limiting stability.

[0030] In some optional embodiments, an avoidance hole 13 is provided at the top of the mounting groove 11. When the button 212 moves toward the movable channel 22, the top end of the movable rod 213 detaches from the movable channel 22 and extends into the avoidance hole 13, so that when the button 212 drives the movable rod 213, the structure of the frame 10 will not interfere with the movement of the movable rod 213.

[0031] In some optional embodiments, support portions 24 are respectively provided on both sides of the mounting base 20, the wheel 30 is rotatably provided between the two support portions 24, the bottom opening of the movable channel 22 is located between the two support portions 24, the button 212 extends outside the bottom opening of the movable channel 22, and is located above the wheel 30. This design is conducive to protecting the button 212, so that the button 212 is not easily collided with other structures in the environment when the frame 10 moves, resulting in false triggering.

[0032] In order to facilitate the formation of the limiting step 12 and simplify the structure of the frame 10, in some optional embodiments, a limiting sleeve 14 is provided in the mounting groove 11, and the limiting sleeve 14 is threadedly engaged with the mounting groove 11, and the limiting sleeve 14 forms a limiting step 12 on the end surface of the mounting groove 11. This design is conducive to simplifying the structure of the frame 10 at the mounting groove 11, thereby simplifying the production process.

[0033] The wheel device with quick-release structure described above can be applied to an auxiliary walking vehicle, and the auxiliary walking vehicle includes the wheel device with quick-release structure. Among them, other components such as handrails can also be arranged on the vehicle frame.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
