DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] In combination with Figures 1 to 6 In the embodiment, the utility model provides a linkage folding type child stroller, the child stroller has two states of unfolding and folding, the child stroller comprises front leg group 1, rear leg group 2, seat cushion group 3 and push handle group 4, and the joint ends of front leg group 1, rear leg group 2 and push handle group 4 are connected with front leg joint 5, rear leg joint 6 and push handle joint 7 respectively, front leg joint 5, rear leg joint 6 and push handle joint 7 are in the same plane and can rotate relative to each other, push handle joint 7 is provided with locking member 8, rear leg joint 6 is provided with locking groove 61 matched with locking member 8, push handle joint 7 and rear leg group 2 are connected through rear leg linkage piece 9, the front end of seat cushion group 3 is movably connected with front leg group 1, the rear end of seat cushion group 3 is connected with rear leg group 2 through seat cushion linkage piece 10, push handle group 4 is provided with folding button 11, and folding button 11 is connected with locking member 8.

[0024] Specifically, front leg group 1, rear leg group 2, seat cushion group 3 and push handle group 4 all comprise a pipe frame composed of multiple pipe rods, front leg joint 5, rear leg joint 6 and push handle joint 7 are respectively inserted and fixed with the pipe frame on the corresponding front leg group 1, rear leg group 2 and push handle group 4, and in order to movably connect rear leg linkage piece 9 and seat cushion linkage piece 10, holes are arranged on the corresponding pipe frames, and the two ends of rear leg linkage piece 9 and seat cushion linkage piece 10 are respectively connected with the holes through pin shafts.

[0025] Push handle joint 7 and rear leg joint 6 are placed in front leg joint 5 after being attached, and holes are also arranged on the side of push handle joint 7 and rear leg joint 6 away from each other, front leg joint 5 is composed of two parallel discs to form a space, and holes are also arranged on the discs, push handle joint 7 and rear leg joint 6 are respectively rotatably connected with front leg joint 5 through pin shafts, and the pin shafts respectively pass through the holes on the joints.

[0026] As Figure 4As shown in the figure, the locking member 8 includes a lock base 81 and a lock tongue 82. The lock tongue 82 is provided with an inclined groove 83. The lock tongue 82 is fitted into the lock base 81 and can slide along the lock base 81. A rivet 84 passing through the inclined groove 83 on the lock tongue 82 is provided on the lock base 81. The lock base 81 is slidably installed in the push handle joint 7. The folding button 11 is connected to the lock base 81 through a traction cable. The lock tongue 82 is placed in the push handle joint 7 and is limited to slide with the push handle joint 7. The lock tongue 82 is connected to the push handle joint 7 through a spring 85. The sliding directions of the lock base 81 and the lock tongue 82 are perpendicular to each other. When the folding button 11 is pressed, the traction cable drives the lock base 81 to slide upward along the inside of the push handle joint 7 and drives the rivet 84 to move upward. The rivet 84 slides along the inclined support, so as to act on the inner wall of the inclined support to make the lock tongue 82 move toward the inside of the push handle joint 7. The lock tongue 82 disengages from the locking groove 61 to complete unlocking. After the folding button 11 is released, the spring 85 pushes the lock tongue 82 to reset and the lock base 81 slides down to complete locking. At the same time, in order to facilitate automatic locking after folding, the lower side of one end of the lock tongue 82 close to the locking groove 61 is an arc structure.

[0027] Furthermore, a locking groove 62 is provided on the rear foot joint 6. During locking, the lower end of the lock base 81 is placed in the locking groove 62 to form a secondary locking, which further improves the locking effect.

[0028] As Figures 1-2 shown in the figure, in this example, one end of the rear foot joint 6背离 the rear foot group 2 is fixedly connected with a front armrest tube 12, and the front armrest tube 12 abuts against the front foot joint 5 to ensure that the rear foot joint 6 can only rotate relative to the front foot joint 5 in one direction, ensuring the stability of the frame.

[0029] On both sides of one end of the seat group 3背离 the front foot group 1, seat joints 13 are provided. The seat joints 13 are axially connected with the seat linkage piece 10. The other end of the seat linkage piece 10 is axially connected with the rear foot group 2. A backrest tube 14 is rotatably connected between the upper ends of the two seat joints 13. During folding, the backrest tube 14 can rotate accordingly, so as to reduce the volume after folding.

[0030] The working principle of the present utility model is as follows: By pressing the folding button 11, the locking member 8 is driven to disengage from the locking groove 61 to unlock the baby stroller. The push handle group 4 rotates toward the rear foot group 2 and drives the rear foot group 2 to rotate toward the front foot group 1 through the rear foot linkage piece 9. The rear foot group 2 drives the seat group 3 to rotate relative to the front foot group 1 through the seat linkage piece 10 until the front foot group 1, the rear foot group 2, the seat group 3 and the push handle group 4 are fitted together to complete the folding and storage of the stroller. The overall structure integrates locking and linkage. The locking effect is firm, the joints shake less, the frame folds compactly, the volume is small, it can be folded with one hand, it is convenient to use, and it is suitable for single-person use with a baby.

[0031] It should be noted that there is an unclear expression "背离" in the original text. I have translated it as "背离" as it is, but it may need to be further clarified according to the actual context.It is to be noted that, in the present text, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions, and the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0032] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
