TECHNICAL FIELD

[0001] The utility model relates to the technical field of camping stroller, especially a folding camping stroller with strong bearing capacity. BACKGROUND

[0002] The folding camping stroller is a portable transport tool specially designed for outdoor camping and hiking, which can help users easily carry camping equipment, food, water and other necessities. The portability and practicality of the folding camping stroller encourage more people to participate in outdoor activities such as camping and hiking, thus promoting a healthy lifestyle.

[0003] The camping stroller mainly consists of a frame, wheels, a folding mechanism and a loading platform. The folding mechanism is usually part of the frame, allowing users to quickly fold the stroller for easy carrying and storage. The loading platform is composed of a bearing bag, a frame and a folding mechanism fixed together. When the frame is folded, the bearing bag is also folded, making it easy to store.

[0004] The existing camping stroller requires high bearing capacity due to the need to load a large number of camping supplies. The existing folding camping stroller mainly uses a bearing bag for bearing, but the bottom of the bearing bag does not have an auxiliary support component. Therefore, the bearing bag may be damaged after long-term use, making it inconvenient to use. SUMMARY

[0005] (I) Technical problems solved

[0006] To solve the above problems of the prior art, the utility model provides a folding camping stroller with strong bearing capacity.

[0009] The auxiliary bearing assembly comprises two fixed plates fixedly connected to the lower surface of the frame, a connecting rod fixedly connected to the adjacent side of each fixed plate, four rotating rods arranged on the outer surface of the frame, a horizontal rod movably connected to the top end of each rotating rod on the same side, a fixed block fixedly connected to the outer surface of the horizontal rod, and a fixed block slidingly connected to the lower surface of the fixed plate.

[0010] The outer surface of the connecting rod is provided with a locking assembly.

[0011] The locking assembly comprises a pin rod arranged in the connecting rod, a clamping block fixedly connected to one end of the pin rod close to the pin rod, an installation block fixedly connected to the other end of the pin rod away from the pin rod, two rotating blocks hingedly connected to the upper surface of the installation block, an arc-shaped plate fixedly connected to the side of the rotating block away from the cross rod, and a threaded cover threadedly connected to the outer surface of the arc-shaped plate.

[0012] As a preferred form of the folding camping cart with high load-bearing capacity, the outer surface of each end of the cross rod is fixedly connected with a sliding block, and the lower surface of the fixed plate is provided with a sliding groove for the sliding of the sliding block and the fixed block.

[0013] As a preferred form of the folding camping cart with high load-bearing capacity, the bottom end of the rotating rod is fixedly connected with a clamping ring, and the clamping ring is clamped on the outer surface of the rack.

[0014] As a preferred form of the folding camping cart with high load-bearing capacity, the connecting rods between the two fixed plates are hingedly connected through the pin rods.

[0015] As a preferred form of the folding camping cart with high load-bearing capacity, the two ends of the pin rod are provided with ring grooves, and the inner side of the arc-shaped plate is provided with an insertion block matched with the ring grooves.

[0017] (Three) beneficial effects

[0018] The utility model provides a kind of folding camping cart with high load-bearing capacity. It has the following beneficial effects:

[0019] 1. The setting of the rotating rod enables the cross rod to slide on the lower surface of the fixed plate towards the center of the load-bearing bag through the fixed block and the sliding block. When the cross rod cannot move further to one end close to the center inside the sliding groove of the lower surface of the fixed plate, the rotating rod supports the cross rod to support the fixed plate, thereby achieving auxiliary support for the load-bearing bag and improving the load-bearing effect.

[0020] 2. The cooperation of the pin rod and the clamping block preliminarily realizes the locking of the pin rod. Then, the rotating block drives the arc-shaped plate and the insertion block to cooperate with the ring groove on the outer surface of the pin rod, and the threaded cover cooperates with the arc-shaped plate to realize the locking of the two arc-shaped plates, finally realizing the locking of the pin rod. The locking of the threaded cover realizes the locking of the pin rod, avoiding the contraction of the camping cart due to external impact during use. BRIEF DESCRIPTION OF DRAWINGS
