[0002] A baby stroller is a child carriage, which is a common tool used by mothers and fathers to take their children out. It is convenient and comfortable, freeing the hands of adults while allowing children to relax. Adults push the stroller for walks, shopping, or self-driving tours. It is very important to facilitate the folding of the stroller. Existing baby strollers are inconvenient to use. Although they have a folding function, they are very inconvenient to operate and have a complicated structure. It is very inconvenient for parents with babies to operate and difficult to fold completely. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as “vertical”, “up”, “down” and “horizontal” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1-5 As shown, a linkage foldable baby stroller comprises a frame, on which a handlebar tube 1, a front leg tube 14, a rear tube 13 and a seat bracket 18 are installed, a folding mechanism is arranged in the middle of the frame, and the folding mechanism comprises a joint seat 5, the upper end of the joint seat 5 is rotatably connected to an upper joint 4 through a pin, the upper joint 4 is connected to the handlebar tube 1, a folding pin 3 is slidably connected to the upper joint 4, the end of the folding pin 3 is plugged into the joint seat 5, the lower end of the joint seat 5 is rotatably connected to a lower joint 8 through a pin, the end of the lower joint 8 is connected to the front leg tube 14, and the lower joint 8 is connected to the seat bracket 18 through a pin, and the seat bracket 18 is connected to the upper joint 4 through the connecting iron sheet 6. When the car collecting pin is used to exert force upward, the front end of the car collecting pin will be disengaged from the inner plane of the joint seat. When the upper joint force is downward, the upper joint drives the seat bracket to move through the connecting iron sheet, thereby rotating the front leg tube, and then causing the lower joint to rotate, so as to quickly set the front leg tube and the handlebar tube close to the rear tube for quick and convenient storage. When unfolding, the upper joint is used to exert force upward, the front leg tube and the handlebar tube are unfolded, the car collecting pin pops out, and the front end of the car collecting pin is stuck on the joint seat to complete the clamping and locking.

[0024] In this embodiment, a long slot hole is opened on the vehicle collecting pin 3, and a spring 2 is installed in the long slot hole. The other end of the spring 2 is connected to the upper joint 4, which is convenient for resetting the vehicle collecting pin and facilitating operation.

[0025] In this embodiment, the seat support 18 includes a front seat tube frame 12 and a rear seat tube frame 9 , the front seat tube frame 12 is connected to a left seat frame connection joint 11 , and the rear seat tube frame 9 is connected to a right seat frame connection joint 10 .

[0026] In this embodiment, the right seat frame connecting joint 10 and the left seat frame connecting joint 11 are rotatably connected, and the rear seat tube frame 9 is connected to the upper joint 4 through the connecting iron sheet 6, which facilitates the folding and storage of the vehicle body structure and facilitates operation.

[0027] In this embodiment, a circular hole 15 is opened below one end of the upper joint 4 close to the joint seat 5, and the circular hole 15 is rotatably connected to the end of the connecting iron sheet 6 through a pin, so as to facilitate the movement of the connecting iron sheet by rotating the upper joint, and realize the downward movement of the upper joint, thereby driving one end of the connecting iron sheet to move upward.

[0028] In this embodiment, a second circular hole 16 is opened on the right seat frame connecting joint 10, and the second circular hole 16 is rotatably connected to the other end of the connecting iron sheet 6 through a pin. The front seat tube frame 12 and the front leg tube 14 are rotatably connected through the pin. After the upper joint moves downward and rotates, the connecting iron sheet is driven to move upward, and the seat frame connecting joint moves right and upward, thereby driving the front seat tube frame and the front leg tube to rotate downward, thereby completing the folding.

[0029] In this embodiment, the outer ring of the joint seat 5 is clamped with a decorative cover 7 , and a warning strip is adhered to the decorative cover 7 .

[0030] In this embodiment, the front end of the front seat tube frame 12 is rotatably connected to a supporting front tube 17 , and a protective cotton sleeve is sleeved on the handlebar tube 1 .

[0031] In this embodiment, two front rollers are installed at the bottom of the front leg tube 14, and two rear rollers are installed at the bottom of the rear tube 13. The diameter of the front rollers is smaller than that of the rear rollers.

[0032] Working principle: When the car is closed, the front end of the closing pin 3 will be disengaged from the inner plane of the joint seat 5 when the upper joint 4 is forced downward, and the upper joint 4 drives the seat bracket 18 to move through the connecting iron sheet 6, drives the connecting iron sheet 6 to move upward, and makes the seat frame connecting joint right 10 move upward, thereby driving the front seat tube frame 12 and the front leg tube 14 to rotate downward (such as Figure 4 ), thereby rotating the front leg tube 14, and then rotating the lower joint 8, so as to quickly set the front leg tube 14 and the handle tube 1 close to the rear tube 13 (such as Figure 5), which is convenient for quick and convenient storage. When unfolding, the upper joint 4 is used to exert force upward, the front leg tube 14 and the handle tube 1 are unfolded, the car collection pin 3 pops out, and the front end of the car collection pin 3 is stuck on the joint seat 5 to complete the card connection and locking.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
