An opening 5 is provided in the receiving groove 4. A first limiting piece 6 is movably provided on the opening 5. The first limiting piece 6 and the opening 5 jointly enclose an installation hole for the connecting rod 2 to be inserted. An elastic member connected to the first limiting piece 6 is provided in the seat 3. The first limiting piece 6 approaches or moves away from the opening 5 under the action of the elastic member to change the size of the installation hole.

[0030] Further, a movable groove 7 for the first limiting piece 6 to extend out is provided on the opening 5.

[0031] Further, the elastic member includes a second limiting piece 8 provided in the seat 3, and a spring 9 is connected between the second limiting piece 8 and the first limiting piece 6.

[0032] Further, the upper end of the second limiting piece 8 is located at the opening 5. A first notch 61 is provided on the first limiting piece 6, and a second notch 81 is provided on the second limiting piece 8. The first notch 61 and the second notch 81 jointly enclose the mounting hole for the connecting rod 2 to be inserted into.

[0033] Further, a hook portion 90 is formed by bending the first notch 61 downward.

[0034] Further, a positioning platform 10 is provided with an outward protrusion on the receiving groove 4, and the opening 5 is provided on the positioning platform 10.

[0035] Further, a fixing rod 11 is provided in the seat 3, and the first limiting piece 6 is rotatably provided on the fixing rod 11.

[0036] Further, a limiting groove 60 for the first limiting piece 6 to move is provided in the seat 3.

[0037] The working principle of the present utility model is:

[0038] As Figure 4 shown, this is a cross-sectional view of the stroller 1 received in the seat 3. The stroller 1 can be fully received in the receiving groove 4 or partially received in the receiving groove 4 according to the use requirements. The core design of this application lies in how the connecting rod 2 realizes the disassembly and installation with the receiving groove 4.

[0039] As Figure 3 shown, as Embodiment 1, a positioning platform 10 can be provided with an outward protrusion at the bottom of the receiving groove 4. For stronger stability, it is preferably provided with 4 positioning platforms 10, and an opening 5 is provided on each positioning platform 10. Two connecting rods 2 are connected to the stroller 1. Figure 2Figure 1 is a schematic structural diagram of the connecting rod 2 not installed on the seat 3. When installation is required, the first limiting piece 6 is toggled. Since the lower end of the first limiting piece 6 is connected to the second limiting piece 8 through a spring 9, when the first limiting piece 6 rotates along the fixed column, the spring 9 will be stretched. As the first limiting piece 6 continues to rotate, the upper end of the first limiting piece 6 will retract into the movable slot 7. At this time, the mounting hole formed by enclosing the first limiting piece 6, the second limiting piece 8, and the opening 5 becomes larger. After the connecting rod 2 is snapped into the mounting hole, the first limiting piece 6 is released, and the spring 9 resumes its deformation to drive the first limiting piece 6 to rotate and reset. The upper end of the first limiting piece 6 extends out of the movable slot 7 and is located within the opening 5. At this time, the mounting hole formed by enclosing the first limiting piece 6, the second limiting piece 8, and the opening 5 becomes smaller, and the aperture of this mounting hole can limit and clamp the connecting rod 2. When disassembly is required, only the first limiting piece 6 needs to be toggled to make the upper end of the first limiting piece 6 retract into the movable slot 7. At this time, the aperture of the mounting hole becomes larger, and the connecting rod 2 can be easily taken out. In this application, the stroller 1 can be other common styles, as long as it can be accommodated in the receiving slot 4, and the connecting rod 2 is arranged on the stroller 1. Figure 4 The stroller 1 shown is only a simple illustration, and it is not the case that only the stroller 1 with this shape can implement the technical solution of this application.

[0040] In order to prevent the mounting hole from becoming too large and unable to clamp the connecting rod 2, an elastic member is connected to the first limiting piece 6 in this application. The setting of the elastic member can drive the first limiting piece 6 to approach or move away from the opening 5, thereby changing the aperture size of the mounting hole to adapt to the clamping of the connecting rod 2. Since the elastic member has the property of self-restoring, it can automatically adjust the size of the mounting hole to clamp the connecting rod 2, and there will be no problem of the connecting rod 2 becoming loose and unable to be limited. In addition, it can also adapt to the clamping of connecting rods 2 with different diameters, and the application range is wider.

[0041] On the basis of the above technical solution, in order to better clamp the connecting rod 2, a first notch 61 is provided on the first limiting piece 6, a second notch 81 is provided on the second limiting piece 8, and a hook portion 90 is provided on the first limiting piece 6. The mounting hole formed by enclosing the first notch 61, the second notch 81, and the hook portion 90 can better match the outer circumference of the connecting rod 2 to clamp the connecting rod 2.

[0042] On the basis of the above technical solution, in order to limit the rotation trajectory of the first limiting piece 6, a limiting slot 60 is provided in the seat 3 in this application. When the first limiting piece 6 rotates, its lower end moves within the limiting slot 60.

[0043] Regarding the stroller 1 of this application, it can be as Figure 6As shown, the stroller 1 is connected to the seat 3 through the quick disassembly and assembly structure of the present application. The stroller can be a foldable model. Since the implementation method of folding the stroller belongs to the conventional means in the technical field, it will not be elaborated herein. The stroller 1 can also be set with the structural cooperation of the frame 1-1 and the vehicle body 1-2. The frame 1-1 is snap-fitted with the vehicle body 1-2. Then, after removing the vehicle body 1-2 from the frame 1-1, the vehicle body 1-2 is connected to the seat 3 through the quick disassembly and assembly structure; or after folding and storing the frame 1-1, the entire stroller 1 is connected to the seat 3 through the quick disassembly and assembly structure.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims.
