[0002] A stroller is a tool vehicle designed to facilitate outdoor activities for infants. There are various models available. Generally, children aged 1 to 2 years play with strollers, while children over 2 years old play with toy cars with wheels. Strollers can bring certain benefits to children's intellectual development and enhance their brain development.

[0003] Some current strollers have relatively complicated folding steps, requiring them to be folded in a specific order and manner. Otherwise, the folded stroller may be too large or unstable. In addition, the position of the baby's arm support is not easy to adjust when sitting on it, and it cannot accommodate more toys and daily necessities, resulting in low practicality. Therefore, a stroller that can be quickly folded and stored is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-folding and storage stroller with advantages such as ease of folding. It solves the problem that some current strollers have relatively cumbersome folding steps, requiring folding in a specific order and manner, otherwise the folded stroller may be too large or unstable to place. At the same time, the position of the baby's arm support is not easy to adjust when sitting on it, and it cannot accommodate more toys and daily necessities, resulting in low practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stroller that can be quickly folded and stored, comprising a stroller body, wherein two connecting components are fixedly installed inside the stroller body, and an adjustment component is provided inside the stroller body;

[0006] The stroller body includes two main rods inside the stroller body. One end of each of the two connecting components is connected to a front rod. A connecting rod is fixedly installed between the two front rods. Front wheels are fixedly installed at both ends of the bottom of the connecting rod. A rear rod is installed at one end of each of the two connecting components. Rear wheels are fixedly installed at the bottom of each of the two rear rods. A crossbar is fixedly installed between the two rear rods. A brake disc is fixedly installed on the outer surface of the crossbar. A handle is fixedly installed between the two main rods. A support plate is installed between the two connecting components.

[0007] The adjustment assembly includes a storage slot inside the support plate, a slide rod fixedly installed inside the storage slot, a movable plate slidably installed on the outer surface of the slide rod, at least ten protrusions fixedly installed on the bottom of the movable plate, a rotating shaft rotatably installed inside the storage slot, a locking rod fixedly installed on the outer surface of the rotating shaft, a return spring fixedly installed on the inner bottom wall of the storage slot, and a rotating rod fixedly installed on the front of the locking rod.

[0008] Preferably, both of the connecting components include a fixed plate, and a fixed plate is connected between each of the main rod, front rod and rear rod. An outer plate, a rotating plate, a movable plate and a movable block are rotatably installed inside each of the two fixed plates.

[0009] Preferably, the rotation points of the outer disc, rotating disc, movable disc, and movable block are all non-concentric, and the outer disc, rotating disc, movable disc, and movable block are fixedly connected to the main rod, support disc, front rod, and rear rod, respectively.

[0010] Preferably, a movable plate is movably installed inside the storage slot, with one end of the movable plate extending to the outside of the support plate.

[0011] Preferably, the ten protrusions are distributed at equal intervals on the bottom of the moving plate, and the end of the lever away from the rotation axis is engaged between two protrusions.

[0012] Preferably, the outer surface of the support plate has an movable hole adapted to the rotating rod, and one end of the rotating rod extends to the outside of the movable hole. The end of the return spring away from the inner wall of the storage groove is fixedly connected to the surface of the clamping rod.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This quick-folding stroller, through the setting of connecting components, allows the stroller body to be folded and stored by simply pushing down the main rod. As the outer disc rotates, its misaligned rotation point design with other components (moving discs and moving blocks) enables these components to rotate and move relative to each other in a specific way. This chain reaction causes the support disc, front rod, and rear rod to gradually approach and fit together, achieving the purpose of folding and storage. This not only simplifies the folding process but also improves the convenience and efficiency of storage.

[0015] 2. This quick-folding stroller features an adjustment mechanism. When the usable area of ​​the support tray needs to be expanded, the rotation of the rotating rod drives the locking lever downwards. The locking lever compresses the return spring, releasing the limit on the moving plate. Pulling the moving plate allows for rapid adjustment of the support tray's usable area. This not only improves the flexibility and practicality of use but also simplifies the operation process, enhances the user experience, and optimizes space utilization. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See also Figure 1-6 This embodiment of a quick-folding stroller includes a stroller body 1, with two connecting components 2 fixedly installed inside the stroller body 1, and an adjustment component 3 provided inside the stroller body 1.

[0025] The stroller body 1 includes two main rods 101 inside the stroller body 1. One end of each of the two connecting components 2 is connected to a front rod 102. A connecting rod 103 is fixedly installed between the two front rods 102. Front wheels 104 are fixedly installed at both ends of the bottom of the connecting rod 103. A rear rod 105 is installed at one end of each of the two connecting components 2. Rear wheels 106 are fixedly installed at the bottom of each of the two rear rods 105. A crossbar 107 is fixedly installed between the two rear rods 105. A brake disc 108 is fixedly installed on the outer surface of the crossbar 107. A handle 109 is fixedly installed between the two main rods 101. A support plate 110 is installed between the two connecting components 2.

[0026] It should be noted that the stroller body 1 is also called a baby stroller or baby hand stroller. It is a "transportation tool" for the baby and needs someone to help push or pull it to move. The stroller body 1 can be assembled by the main rod 101, front rod 102, connecting rod 103, front wheel 104, rear rod 105, rear wheel 106, crossbar 107, brake disc 108, armrest 109, support plate 110 and connecting component 2.

[0027] The adjustment component 3 includes a storage slot 301 inside the support plate 110, a slide rod 302 fixedly installed inside the storage slot 301, a movable plate 303 slidably installed on the outer surface of the slide rod 302, at least ten protrusions 304 fixedly installed on the bottom of the movable plate 303, a rotating shaft 305 rotatably installed inside the storage slot 301, a locking rod 306 fixedly installed on the outer surface of the rotating shaft 305, a return spring 307 fixedly installed on the inner bottom wall of the storage slot 301, and a rotating rod 308 fixedly installed on the front of the locking rod 306.

[0028] Specifically, when it is necessary to expand the usable area of ​​the support plate 110, the rotation of the rotating rod 308 drives the locking rod 306 to rotate downward. The locking rod 306 squeezes the return spring 307, releases the limit on the moving plate 303, and pulls the moving plate 303, thus realizing the rapid adjustment of the usable area of ​​the support plate 110.

[0029] Both connecting components 2 include a fixed plate 205. A fixed plate 205 is connected between each main rod 101, front rod 102, and rear rod 105. An outer plate 201, a rotating plate 202, a movable plate 203, and a movable block 204 are rotatably installed inside each of the two fixed plates 205. The rotation points of the outer plate 201, rotating plate 202, movable plate 203, and movable block 204 are not concentric. The outer plate 201, rotating plate 202, movable plate 203, and movable block 204 are fixedly connected to the main rod 101, the support plate 110, the front rod 102, and the rear rod 105, respectively.

[0030] Specifically, the user pushes the main rod 101 downwards. This action marks the beginning of the folding process. Since the main rod 101 is fixedly connected to the outer disc 201, the outer disc 201 rotates as the main rod 101 moves downwards. As the outer disc 201 rotates, its misaligned rotation point design with other components—rotating disc 202, movable disc 203, and movable block 204—allows these components to rotate and move relative to each other in a specific way. This chain reaction causes the support disc 110, front rod 102, and rear rod 105 to gradually approach and fit together. When the main rod 101 continues to move downwards to a certain position, all the rods—main rod 101, front rod 102, rear rod 105, and support disc 110—will fit tightly together, forming a compact folding structure.

[0031] In summary, this quick-folding stroller, through the setting of the connecting component 2, allows the stroller body 1 to be folded and stored by simply pushing the main rod 101 downwards. As the outer disc 201 rotates, its misaligned rotation point design with other components such as the rotating disc 202, the movable disc 203, and the movable block 204 enables these components to rotate and move relative to each other in a specific way. This chain reaction causes the support disc 110, the front rod 102, and the rear rod 105 to gradually approach and fit together, achieving the purpose of folding and storage. This not only simplifies the folding process but also improves the convenience and efficiency of storage.

[0032] Furthermore, by setting the adjustment component 3, when it is necessary to expand the usable area of ​​the support plate 110, the rotation of the rotating rod 308 drives the locking rod 306 to rotate downwards. The locking rod 306 squeezes the reset spring 307, releasing the limit on the moving plate 303. Pulling the moving plate 303 can quickly adjust the usable area of ​​the support plate 110, which not only improves the flexibility and practicality of use, but also simplifies the operation process, enhances the user experience, and optimizes space utilization.
