[0005] Furthermore, the wheel axle is freely rotatably inserted in the shaft sleeve.

[0006] Furthermore, the riser seat is provided with a cutout for placing the locking piece.

[0007] Furthermore, the locking piece is L-shaped, the front end of the long straight portion of the locking piece is hinged on the riser seat, and the rear end of the short straight portion of the locking piece is bent away from the riser seat to form an L-shaped paddle, and the L-shaped paddle is located outside the riser seat.

[0008] Furthermore, a notch is provided on the short straight portion of the locking sheet, and the spring is located in the notch.

[0009] Furthermore, the wheel is fixed on the axle.

[0010] Furthermore, the riser is vertically installed on the camping vehicle, and the riser seat is fixedly sleeved on the bottom of the riser.

[0011] Through the above scheme, the utility model has at least the following advantages: the quick-release mechanism can lock and unlock the wheel through the cooperation of the locking plate and the axle, the structure is simple, the design is ingenious, when the wheel needs to be replaced, the locking plate and the axle are unlocked to pull the old wheel from the camping car, and then the new wheel can be inserted into the axle sleeve, the wheel is easy to disassemble and assemble, and the use of screws to fix it is avoided, which saves time and effort and has low cost.

[0012] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Embodiment: A quick-release mechanism comprises a riser seat 1, a locking plate 2, a spring 6, a wheel axle 4 and a sleeve 5, wherein the riser seat is fixedly sleeved on the riser 3, the locking plate is hinged on the riser seat, the spring is connected between the locking plate and the riser seat, the sleeve is fixed in the riser seat, the wheel axle is inserted in the sleeve, a protrusion 21 is provided on the locking plate, the riser seat and the sleeve are both provided with openings for the protrusion to pass through, and a circle of grooves 41 for the protrusion to be inserted into is provided on the wheel axle.

[0021] The wheel axle is freely rotatable and inserted in the shaft sleeve.

[0022] The standpipe seat is provided with a cutout 11 for placing the locking piece.

[0023] The locking piece is L-shaped, the front end of the long straight portion of the locking piece is hinged on the riser seat, and the rear end of the short straight portion of the locking piece is bent away from the riser seat to form an L-shaped paddle 22, and the L-shaped paddle is located outside the riser seat.

[0024] A notch 23 is provided on the short straight portion of the locking piece, and the spring is located in the notch.

[0025] The wheel is fixed on the axle.

[0026] The riser pipe is vertically installed on the camp cart, and the riser pipe seat is fixedly sleeved on the bottom of the riser pipe.

[0027] The disassembly and assembly method of the quick-release mechanism is as follows: Under normal use of the camp cart, the convex block on the locking piece is inserted into the groove of the axle. At this time, the axle can only rotate in the bushing and cannot move up and down. When the wheel needs to be replaced, use your hand to dial the L-shaped dial on the locking piece outwards to make the locking piece rotate, driving the convex block out of the groove of the axle. At this time, the old wheel can be pulled out of the riser pipe seat together with the axle. Then, insert the new wheel together with the axle into the bushing, and then release the L-shaped dial. Under the action of the spring, the locking piece returns to its original position. At this time, the convex block on the locking piece passes through the openings of the riser pipe and the bushing and enters the groove of the axle, locking the upper and lower axles in the riser pipe seat, thus completing the replacement of the wheel. The whole disassembly and assembly process is fast and convenient, can be completed independently, and saves time and effort.

[0028] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
