Description

Technical Field

[0001] This utility model relates to the field of baby stroller technology, and in particular to a large joint structure of the entire stroller platform. Background Technology

[0002] Baby strollers are outdoor travel tools designed specifically for infants and toddlers, mainly for babies aged 0-3 years, and have multiple functions to adapt to different scenarios.

[0003] Most existing baby strollers have a one-piece structure design, which makes it difficult to fold the frame. This makes the stroller take up a lot of space when not in use, making it inconvenient to store. To address this, we provide a stroller with a large joint structure for the entire platform. Utility Model Content

[0004] To address the problem of inconvenience in storing the frame due to the difficulty in folding it in the aforementioned background technology, this utility model provides a complete large joint structure for the vehicle platform.

[0005] This utility model is achieved using the following technical solution: a complete large joint structure for a vehicle platform, including a rear foot joint, with a large joint gear rotatably connected inside the rear foot joint. A large joint gear spring is provided between the large joint gear and the rear foot joint. A turntable is provided on one side of the large joint gear, and a torsion spring is provided on the turntable. A handle joint is provided on one side of the rear foot joint, and the rear foot joint and the handle joint are connected by a large joint rivet. A connecting rod is provided on one side of the handle joint, and the connecting rod is connected to the handle joint by a fixing screw. A nut is threaded onto the external part of the fixing screw. A retraction lever is provided on the other side of the handlebar joint. A retraction steel wire is added between the retraction lever and the turntable. A rubber-coated iron plate is fixedly connected to the rear foot joint. A front foot joint is provided on the rubber-coated iron plate of the rear foot joint. An inner iron plate of the front foot joint is provided inside the front foot joint. A locking pin is provided on the inner iron plate of the front foot joint. A locking pin is provided between the locking pin and the connecting rod. When the handlebar is retracted, it can drive the locking pin and the locking pin to disengage together. The rubber-coated iron plates of the front foot joint and the rear foot joint are connected by a front foot joint screw. Two nuts are connected to the external threads of the front foot joint screw.

[0006] As a further improvement to the above solution, the interior of the hind leg joint is provided with a tooth groove that matches the gear of the large joint.

[0007] As a further improvement to the above solution, the large joint gear is an incomplete gear.

[0008] As a further improvement to the above solution, the two ends of the large joint gear spring abut against the large joint gear and the rear foot joint, respectively.

[0009] As a further improvement to the above solution, a handle joint cover is fixedly connected to the outside of the handle joint.

[0010] As a further improvement to the above solution, the rubber-coated iron sheet of the hind leg joint is provided with an upper arc-shaped groove.

[0011] As a further improvement to the above solution, a protrusion with an integral structure is provided on one side of the turntable.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a pull handle to turn the dial, causing the large joint gear to disengage and unlock. Pressing down on the handle pushes the connecting rod, simultaneously unlocking the locking pin and the locking stud. After fully unlocking, continuing to press down on the handle pushes the connecting rod, which in turn pushes the locking stud along the upper arc-shaped groove on the rubber-coated metal plate of the rear leg joint until it folds up, thus enabling rapid folding of the stroller frame. It is highly practical. Conversely, lifting the handle pulls the connecting rod, causing the locking stud to move along the upper arc-shaped groove on the rubber-coated metal plate of the rear leg joint until the locking pin inserts into the rear leg joint and locks in place. At the same time, the locking stud enters the end of the groove and locks in place, thus enabling rapid unfolding of the stroller frame. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figure 1-5 This embodiment of a platform assembly includes a rear foot joint 1. A large joint gear 2 is rotatably connected inside the rear foot joint 1. A large joint gear spring 3 is provided between the large joint gear 2 and the rear foot joint 1. A turntable 4 is provided on one side of the large joint gear 2, and a torsion spring 5 is provided on the turntable 4. A handle joint 6 is provided on one side of the rear foot joint 1. The rear foot joint 1 and the handle joint 6 are connected by a large joint rivet 7. A connecting rod 8 is provided on one side of the handle joint 6, and the connecting rod 8 is connected to the handle joint 6 by a fixing screw 9. A nut 10 is threaded onto the outside of the fixing screw 9. A retraction rod 11 is provided on the other side of the handle joint 6. A retraction steel wire 12 is added between the retraction rod 11 and the turntable 4. A rubber-coated iron sheet 13 is fixedly connected to the rear foot joint 1. The front foot joint 14 is provided, and the inner iron plate 15 of the front foot joint 14 is provided inside the front foot joint 15. The iron plate 15 of the front foot joint is provided with a locking pin 16. The locking pin 16 and the connecting rod 8 are provided with a locking pin 17. When the handle is closed, the locking pin 16 and the locking pin 17 can be disengaged together. The front foot joint 14 and the rubber-coated iron plate 13 of the rear foot joint are connected by the front foot joint screw 18. The screw 18 of the front foot joint is threaded with a nut 19. The rear foot joint 1 has a tooth groove that matches the gear 2 of the large joint. The two ends of the gear spring 3 of the large joint abut against the gear 2 of the large joint and the rear foot joint 1, respectively. The handle joint 6 is fixedly connected with the handle joint cover 20. The rubber-coated iron plate 13 of the rear foot joint has an upper arc-shaped groove. The turntable 4 has an integral protrusion on one side.

[0024] The implementation principle of the large joint structure of the stroller frame in this embodiment is as follows: by pulling the turntable 4 with the handle, the large joint gear 2 will disengage and unlock. By pressing down the handle, the connecting rod 8 will be pushed, so that the locking pin 16 and the locking pin 17 can be unlocked at the same time. After they are fully unlocked, the handle will be pressed down to push the connecting rod 8. The connecting rod 8 will push the locking pin 17 to move along the upper arc-shaped groove on the rubber-coated iron plate 13 of the rear leg joint until it is closed, thereby realizing the quick folding of the stroller frame. Conversely, by lifting the handle and pulling the connecting rod 8, the locking pin 17 will move along the upper arc-shaped groove on the rubber-coated iron plate 13 of the rear leg joint until the locking pin 16 is inserted into the rear leg joint 1 for locking. At the same time, the locking pin 17 will enter the end of the groove for locking, thereby enabling the stroller frame to be quickly unfolded.

[0025] Example 2:

[0026] The further improvement of this embodiment based on embodiment 1 is that the large joint gear 2 is an incomplete gear.
