However, existing strollers still have many shortcomings in terms of storage and folding, making it difficult to meet the diverse needs of users.

[0003] Traditional baby strollers often employ complex mechanical folding systems, such as multi-segment linkage structures. While these designs can achieve folding, the operation is cumbersome, often requiring users to operate multiple latches or buttons simultaneously, consuming a significant amount of time and effort. Furthermore, some structural designs demand a high level of force and angle from the user, making it difficult for parents or elderly individuals unfamiliar with the operation process to fold quickly. In addition, the complex mechanical structure results in a large number of parts, which can easily lead to wear and tear, jamming, and other problems after prolonged use, reducing the stroller's lifespan and reliability. Therefore, a baby stroller that is easy to store and fold is proposed to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This embodiment of a baby stroller that is easy to store and fold includes two rear support rods 101, two rear wheels 102, two front support rods 103, two front wheels 104, armrests 105, seats 106 and guardrails 107. Folding components 2 are installed at the connection points of the two rear support rods 101, the front support rods 103 and the guardrails 107.

[0022] Rear wheels 102 are fixedly installed at one end of each of the two rear support rods 101, and front wheels 104 are fixedly installed at one end of each of the two front support rods 103. A seat 106 is fixedly installed on one side of the armrest 105, and a guardrail 107 is rotatably installed on the surface of the seat 106.

[0023] The folding assembly 2 includes two connecting cylinders 201 located inside the folding assembly 2. A first spring 203 is fixedly installed on one side of the inner wall of each of the two connecting cylinders 201. An inclined pressure block 202 is movably installed inside each of the two connecting cylinders 201. A first tooth 204 is installed inside each of the two connecting cylinders 201. A cylinder 206 is installed on the top of each of the two connecting cylinders 201. A mounting block tooth 207 is inserted into the bottom of each of the two cylinders 206. A second spring 205 is installed between the bottom of each of the two cylinders 206 and the connecting cylinder 201. An mounting cylinder 208 is installed on the top of each of the two cylinders 206. A third spring 209 is installed inside each of the two mounting cylinders 208. A second tooth 210 is placed inside each of the two mounting cylinders 208. A screw 211 is installed through each of the two connecting cylinders 201, the cylinders 206 and the mounting cylinders 208. Nuts 212 are threaded onto the surfaces of the two screws 211.

[0024] In this embodiment, when the stroller needs to be folded, the second tooth 210 inside the mounting cylinder 208 is operated to compress the third spring 209, causing the second tooth 210 to separate from the meshing structure of other components. Then, force is applied to components such as the armrest 105, rear support rod 101, and front support rod 103, causing the cylinder 206 to move relative to the connecting cylinder 201, compressing the second spring 205. At the same time, the mounting block tooth 207 disengages from the first tooth 204. During this process, the inclined pressure block 202 is squeezed inside the connecting cylinder 201, compressing the first spring 203, ultimately achieving relative rotation and folding of each component.

[0025] This folding method is easy to operate, and users can complete the folding without complicated operations, saving time and effort. Through the cooperation of multiple springs No. 1 spring 203, No. 2 spring 205, No. 3 spring 209 and the gear structure, the folding is smooth while ensuring the stability of the trolley structure when unfolded, thus improving safety and stability.

[0026] One end of each of the two nuts 212 is attached to one side of the mounting cylinder 208, and the two screws 211 respectively pass through the interior of the connecting cylinder 201, the inclined pressure block 202, the first tooth 204, the second spring 205, the cylinder 206, the mounting block tooth 207, the mounting cylinder 208, the third spring 209, and the second tooth 210. Each of the two mounting block teeth 207 has four teeth installed on one side, and both sets of teeth extend into the cylinder 206.

[0027] In this embodiment, the nut 212 fits into the mounting cylinder 208, and the screw 211 passes through each component, tightly connecting the connecting cylinder 201, the cylinder 206, the mounting cylinder 208, etc. into a whole, preventing the components from loosening or shifting during use, ensuring the overall structural stability of the folding assembly 2, and thus ensuring the normal use of the baby stroller.

[0028] The screw 211 passes through the inclined pressure block 202, spring 203, spring 205, spring 209, tooth 204, mounting block tooth 207, tooth 210, etc., and can accurately transmit the operating force, so that each component works together in a preset manner; for example, during operation, the force is transmitted through the screw 211, compressing the spring and driving the tooth structure to separate or engage, so as to achieve smooth folding and unfolding and ensure stable and reliable function.

[0029] In summary, this easy-to-store and foldable stroller allows for easy folding. When folding is required, the second tooth 210 inside the mounting cylinder 208 is operated to compress the third spring 209, causing the second tooth 210 to disengage from the meshing structure of other components. Next, force is applied to components such as the armrest 105, rear support rod 101, and front support rod 103, causing the cylinder 206 to move relative to the connecting cylinder 201, compressing the second spring 205. Simultaneously, the mounting block tooth 207 disengages from the first tooth 204. During this process, the inclined pressure block 202 is compressed within the connecting cylinder 201, compressing the first spring 203. Ultimately, this achieves relative rotation and folding of all components, allowing for stroller folding without complex operations, saving time and effort, and improving ease of use.

[0030] Furthermore, the nut 212 fits snugly against the mounting cylinder 208, and the screw 211 passes through the connecting cylinder 201, the cylinder 206, and other components, tightly connecting them into a whole to prevent loosening and displacement. At the same time, the screw 211 passes through the inclined pressure block 202, the first spring 203, the second spring 205, the third spring 209, the first tooth 204, the mounting block tooth 207, and the second tooth 210, working together to ensure smooth folding, a stable structure when unfolded, and improved safety and stability.
