Abstract
Description
Technical Field
[0001] This utility model relates to the field of baby product technology, specifically to a baby stroller folding device. Background Technology
[0002] To facilitate use, most existing strollers adopt a foldable design that can be stored. For example, the Chinese utility model patent with publication number CN203332181U uses a pin-type structure for locking. The stroller can be folded up after the pin is removed. However, this design uses a clutch line operation, which can easily lead to problems such as loosening of the line and wear of sliding parts after long-term use, reducing the stability of use. Utility Model Content
[0003] The purpose of this utility model is to provide a reasonably designed stroller folding device that addresses the defects and shortcomings of the existing technology, thereby solving the aforementioned deficiencies.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes two symmetrically arranged connecting parts, each connecting part is provided with a latch for connecting a sleeping basket, each connecting part is connected to a transverse connecting rod on its inner side, the inner end of the transverse connecting rod is connected to a longitudinal connecting rod perpendicular to it, a transverse handle perpendicular to the two longitudinal connecting rods is connected between them, a connecting pin for engaging with the seat is slidably installed inside the connecting part, and a folding button is driven to the connecting pin.
[0005] Preferably, the retractable button has two symmetrical drive ramps on its inner side. Inside the horizontal grip, on both sides of the retractable button, there are drive rods. On the opposite ends of the two drive rods, there are driven sliders. The driven sliders fit into the drive ramps. When the retractable button is pressed inward, it will push the two driven sliders to move relative to each other.
[0006] Preferably, a second driving ramp is connected to the end of the drive rod away from the end of the return button, and a pusher is provided in the longitudinal connecting rod. A groove is opened on the side of the tail end of the pusher. When the drive rod slides toward the end of the return button, the second driving ramp will drive the pusher to slide.
[0007] Preferably, the transverse connecting rod has a circular hole, and a cylindrical movable part is slidably installed in the hole. A connecting pin is connected to the front end of the movable part. A rotating shaft is provided at the rear of the movable part. A thread is connected to the front end of the rotating shaft. A threaded hole matching the thread is opened at the rear end of the movable part. The front end of the thread is located in the threaded hole. A hole is opened on the side of the rotating shaft. A pushing rod is connected to the front end of the pushing part. The pushing rod is aligned with the edge of the hole.
[0008] Preferably, the latch includes a rotatably mounted handle with a locking pawl rotatably connected to the handle.
[0009] The beneficial effects of this utility model after adopting the above structure are: This application has a simple structure. Through a mechanical transmission connection, pressing the retraction button will drive the two connecting pins to retract synchronously, making it easy to retract the vehicle. It is simple and convenient to use. Attached Figure Description

[0012] 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.
[0013] See Figures 1-6 As shown, it includes two symmetrically arranged connectors 4. The connectors 4 are equipped with latches 5 for connecting the bassinet. Each connector 4 has a transverse link 3 connected to its inner side. The inner end of the transverse link 3 is connected to a longitudinal link 2 perpendicular to it. A transverse handle 1 perpendicular to both longitudinal links 2 is connected between the two longitudinal links 2. A connecting pin 16 for engaging with the seat is slidably installed inside the connector 4. The folding button 6 is driven to the connecting pin 16. The retractable button 6 has two symmetrical drive ramps 7 on its inner side. The horizontal handle 1 is located on both sides of the retractable button 6, and each of them has a drive rod 8. Each of the two drive rods 8 has a driven slider 9 on its opposite end. The driven slider 9 fits in contact with the drive ramp 7. When the retractable button 6 is pressed inward, it will push the two driven sliders 9 to move relative to each other. There is a spring behind the retractable button 6. After the retractable button 6 is pressed, the spring can assist it in returning to its original position. A second driving ramp 10 is connected to the end of the drive rod 8 away from the end of the return button 6. A pusher 11 is provided in the longitudinal connecting rod 2. A groove is opened on the side of the tail end of the pusher 11. When the drive rod 8 slides toward the end of the return button 6, the second driving ramp 10 will drive the pusher 11 to slide. A circular hole is opened in the transverse connecting rod 3, and a cylindrical movable part 15 is slidably installed in the hole. A connecting pin 16 is connected to the front end of the movable part 15. A rotating shaft 13 is provided at the rear of the movable part 15. A thread 14 is connected to the front end of the rotating shaft 13. A threaded hole matching the thread 14 is opened at the rear end of the movable part 15. The front end of the thread 14 is located in the threaded hole. A hole is opened on the side of the rotating shaft 13. A push rod 12 is connected to the front end of the pusher 11. The push rod 12 is aligned with the edge of the hole. Springs for resetting are provided at the rear of the pusher 11 and the drive rod 8. A coil spring is provided at the rear end of the rotating shaft 13 to assist in resetting. The latch 5 includes a rotatably mounted handle 501, on which a locking claw 502 for locking is rotatably connected.
[0014] When in use, the latch 5 is used to connect to the upper bassinet, and the connecting pin 16 is used to insert into the lower support leg for connection. When retracting the vehicle, pressing the retract button 6 causes the drive lever 8 to slide relative to it. Figure 6 Taking the perspective as an example, at this time, the drive rod 8 slides to the right, pushing the pusher 11 to move upward, and then pushing the rod 12 to slide upward and insert into the hole of the rotating shaft 13, so that the rotating shaft 13 rotates and the thread 14 rotates. Through the thread 14, the movable part 15 moves backward, thereby driving the connecting pin 16 to move inward, realizing the retraction of the connecting pin 16, and the vehicle can be retracted.
[0015] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.
[0016] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
