[0004] To solve the above existing technical problems, the present invention adopts the following scheme: A collapsible camping cart includes a front bracket, a rear bracket, side brackets, front wheels, and rear wheels. The front bracket and the rear bracket are symmetrical structures. Both ends of the folding rods on the front bracket and the rear bracket are installed on the clamping members through rotating shafts. The clamping members are sleeved and installed on the two side brackets. A three-way pipe is installed at the bottom of the two side brackets. The three-way pipe is installed and connected to the base through a rotating shaft. Front wheels and rear wheels are installed on the base.

[0005] Preferably, the folding rod is formed by the movable connection of a first rotating bracket and a second rotating bracket. An unlocking sleeve is installed on the outside of the second rotating bracket. An unlocking button is embedded on the surface of the unlocking sleeve. The unlocking button passes through the unlocking sleeve and abuts against a metal hook. The bottom of the metal hook is inserted and installed on the mounting sleeve. Both sides of the bottom of the mounting sleeve are connected to the swing piece. The bottom of the swing piece is installed on the base.

[0006] Preferably, the base is composed of a third rotating bracket and a fourth rotating bracket. A support sleeve is installed on the outside of the fourth rotating bracket. A lifting rod is installed on the support sleeve. The lifting rod is installed at the bottom of the mounting sleeve.

[0007] Preferably, a fixed bracket is installed on the side bracket, and a fifth rotating bracket is installed on the two fixed brackets.

[0008] Preferably, a positioning sleeve is installed on the outside of the clamping member, and a support rod is installed on the two corresponding positioning sleeves.

[0009] Preferably, a plurality of sliding sleeves are sleeved on the folding rod.

[0010] The present invention adopts the above technical solution to provide a camping cart that is convenient to fold. By optimizing the design of the adjustment structure, the camping cart can achieve convenient and stable height adjustment, improving the convenience and safety of use. Compared with the prior art, it has the following advantages: 1. Through the structural design of the rotating shaft, clamping parts, unlocking sleeves, etc., simply operating the unlocking button can achieve the folding of the folding rod and the disassembly and folding between the brackets, greatly shortening the folding time and reducing the operation difficulty. Even users who use it for the first time can quickly master the folding method.

[0011] 2. The symmetric front and rear bracket structures, as well as the cooperation of components such as the tee pipe, fixed bracket, and support rod, enable the camping cart to have good stability when unfolded, can bear the transportation of items with a large weight, and is not prone to shaking, falling apart, etc., ensuring the use safety.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] As Figures 1 to 4As shown in the figure, a camping vehicle that is convenient for folding and unfolding includes a front bracket 1, a rear bracket 2, side brackets 3, front wheels 4, and rear wheels 5. The front bracket 1 and the rear bracket 2 are symmetric structures. Both ends of the folding rods 6 on the front bracket 1 and the rear bracket 2 are installed on the clamping parts 7 through rotating shafts. The clamping parts 7 are sleeved and installed on the two side brackets 3. A three-way pipe 8 is installed at the bottom of the two side brackets 3. The three-way pipe 8 is installed and connected to the base 9 through a rotating shaft. The front wheels 4 and the rear wheels 5 are installed on the base 9. The folding rod 6 is formed by the activity connection of a first rotating bracket 10 and a second rotating bracket 11. An unlocking sleeve 12 is installed on the outside of the second rotating bracket 11. An unlocking button 13 is embedded on the surface of the unlocking sleeve 12. After passing through the unlocking sleeve 12, the unlocking button 13 abuts against the metal hook 14. The bottom of the metal hook 14 is inserted and installed on the mounting sleeve 15. The two bottom sides of the mounting sleeve 15 are connected to the swing pieces 16. The bottom of the swing pieces 16 is installed on the base 9. The base 9 is composed of a third rotating bracket 17 and a fourth rotating bracket 18. A support sleeve 19 is installed on the outside of the fourth rotating bracket 18. A lifting rod 20 is installed on the support sleeve 19. The lifting rod 20 is installed at the bottom of the mounting sleeve 15. A fixed bracket 21 is installed on the side bracket 3. A fifth rotating bracket 22 is installed on the two fixed brackets 21. A positioning sleeve 23 is installed on the outside of the clamping part 7. A support rod 24 is installed on the two corresponding positioning sleeves 23. A number of sliding sleeves 25 are sleeved on the folding rod 6.

[0015] During actual operation, a number of sliding sleeves 25 are installed on the folding rod 6. Corresponding ropes or mesh bags can be installed on the sliding sleeves 25, or on the support rods 24 installed on the positioning sleeves 23, which can also be used to install corresponding sunscreen products to increase the comfort of the overall camping. The fifth rotating bracket 22 can rotate outward 90° along the fixed bracket 21 to form a hanging bracket, increasing the usable space. When it is necessary to fold and unfold the camping vehicle after the play, press the unlocking button 13. The bottom of the unlocking button 13 pushes the top of the metal hook 14 to both sides, so that the bottom of the metal hook 14 disengages from the mounting sleeve 15 to achieve unlocking. After unlocking, slightly lift the first rotating bracket 10 and the second rotating bracket 11. When there is a certain angle between the first rotating bracket 10 and the second rotating bracket 11, move the two side brackets 3 towards the middle. At this time, under the action of the rotating joints, the first rotating bracket 10 and the second rotating bracket 11 will rotate relative to each other. The lifting rod 20 will synchronously drive the third rotating bracket 17 and the fourth rotating bracket 18 to move upward from the bottom. The two swing pieces 16 will also move towards the direction of the lifting rod 20. The support structure on the base 9 will also rotate 90° and lean against the inner sides of the two side brackets 3, thus completing the folding of the entire camping vehicle, with a small footprint and being convenient to carry.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
