DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.
[0030] The embodiments of the present utility model will be described below according to its overall structure.
[0031] A folding baby stroller, as Figures 1-5 shown, includes a fixed block 1. A seat 5 is rotatably connected to the top of the fixed block 1. Backrests 22 and guardrails 23 are installed on both sides of the seat 5, and the backrests 22 and guardrails 23 can rotate on both sides of the seat 5, so that the folding and storage of the seat 5 can be realized. A number of ventilation holes 24 are provided on the backrests 22, enabling the air inside and outside the backrests 22 to circulate, reducing the discomfort of children caused by stuffiness during long-term sitting. At the same time, a front fork tube 2 is connected to the bottom of the fixed block 1, and a rear fork tube 3 is rotatably connected to the bottom of the fixed block 1, allowing the rear fork tube 3 to rotate close to the front fork tube 2 at the bottom of the fixed block 1, thus realizing the folding of the baby stroller. At the same time, universal wheels 4 are installed on both sides of the front fork tube 2 and the rear fork tube 3, so the stroller can move in multiple directions, facilitating the improvement of the flexibility of the baby stroller.
[0032] Subsequently, a push handle 9 is rotatably connected to the surface of the fixed block 1. A movable rod 10 is slidably connected to the top of the push handle 9, enabling the movable rod 10 to slide within the push handle 9. First and second chutes 14 and 17 with matching dimensions are provided on the outer surface of the push handle 9, and the first chute 14 is located above the second chute 17. A slider 12 that fits the first chute 14 is slidably connected to the surface of the movable rod 10. Therefore, when the slider 12 is located in the first chute 14 and the second chute 17 respectively, the fixing of the movable rod 10 at different positions can be realized, and the slider 12 is connected to the movable rod 10 through a first return spring 13. Thus, after the force applied to the slider 12 disappears, it can be driven to reset by the first return spring 13. A top cover 18 is slidably connected to the bottom of the push handle 9, and the top cover 18 and the push handle 9 are connected through a second return spring 19. One end of a hook 21 is movably connected to the top of the top cover 18. The hook 21 is connected to the push handle 9 through a shaft. A hanging pin 20 is provided on the surface of the fixed block 1, and the other end of the hook 21 contacts the hanging pin 20. Therefore, when the movable rod 10 slides to the bottom inside the push handle 9, the bottom of the movable rod 10 can squeeze one end of the hook 21. Through the rotational action of the shaft, the other end of the hook 21 is disengaged from the hanging pin 20, releasing the fixation of the push handle 9, enabling the push handle 9 to rotate freely and approach the rear fork tube 3 to complete the storage action.
[0033] A sliding sleeve 6 is slidably connected to the surface of the front fork tube 2. A first inclined rod 7 is hingedly connected between the sliding sleeve 6 and the seat 5, and a second inclined rod 8 is hingedly connected between the sliding sleeve 6 and the rear fork tube 3. Therefore, when the stroller is unfolded, the designs of the first inclined rod 7 and the second inclined rod 8 form a triangular support structure, tightly connecting the seat 5, the front fork tube 2, and the rear fork tube 3 together, effectively dispersing the forces exerted on the stroller during use, enhancing the structural stability of the entire stroller. And when the baby stroller is folded, the first inclined rod 7 and the second inclined rod 8 can change their positions as the sliding sleeve 6 slides, enabling the seat 5 and the rear fork tube 3 to be smoothly folded together.
[0034] Furthermore, a connecting member 11 is installed at the top of the push handle 9. A movable block 15 is hingedly connected to the surface of the connecting member 11. A convex block 16 is fixedly connected to one side of the movable block 15. Therefore, the convex block 16 moves synchronously with the movable block 15, and the convex block 16 is in alignment with the position of the first chute 14. When driving the movable block 15 to rotate, the convex block 16 can squeeze the slider 12 located in the first chute 14, thereby releasing the fixing effect on the movable rod 10, enabling the movable rod 10 to move downward within the push handle 9.
[0035] Therefore, during use, the baby stroller is kept unfolded through the stable connection of the seat 5, the front fork tube 2, the rear fork tube 3, and the fixing block 1, so that it can be used. And when folding, the sliding sleeve 6 slides on the front fork tube 2, and the first inclined rod 7 and the second inclined rod 8 change their positions as the sliding sleeve 6 slides, enabling the seat 5 and the rear fork tube 3 to be smoothly folded together. Then, the movable block 15 is rotated to squeeze the slider 12, causing it to move backward from the first chute 14, releasing the fixation of the movable rod 10. When the movable rod 10 moves downward to the second chute 17, the first return spring 13 drives the slider 12 to reset and enter the second chute 17, realizing the re-fixation of the movable rod 10. At the same time, the bottom of the movable rod 10 squeezes one end of the hook 21. Through the rotational action of the shaft, the other end of the hook 21 is disengaged from the hanging pin 20, releasing the fixation of the push handle 9, enabling the push handle 9 to rotate freely and approach the rear fork tube 3, completing the storage action, which helps to fold the push handle 9, avoiding it being too long to affect the storage after folding, thus facilitating the user to carry and store.
[0036] At the same time, a first footrest 27 is installed on the outer surfaces of both the front fork tube 2 and the rear fork tube 3, allowing children to place their feet on it, which helps improve the safety and stability of children's riding. A second footrest 28 is installed on the outer surface of the rear fork tube 3, which can provide a force application point for the user, enabling the front fork tube 2 to be lifted, thus helping the stroller to smoothly cross these obstacles. A first handle 25 is fixedly connected to one side of the seat 5, which is convenient for being converted into a carrying handle after the stroller is folded, facilitating its carrying. A second handle 26 is installed on the top of the movable rod 10, so that the stroller can be better pushed for operation.
[0037] In this embodiment, damping structures are provided at both the rotational connection and the sliding connection of the structure. Therefore, when the external force is small, it cannot drive the structure to move, avoiding affecting the use of the stroller.
[0038] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present invention, make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
