AI Technical Summary
The existing stroller waist seat protector connector is prone to falling off or is difficult to disassemble.
A waist stool buckle structure is designed. By using an interference fit between the limiting groove and the plug, and setting a hole at the end of the slide rail groove, a quick release function is achieved by pressing the end of the plug. Combined with the limiting part and the convex surface design, the buckle is ensured to be firmly connected.
It achieves a secure connection between the lumbar support plate and the connecting insert, preventing them from falling off, and allows for quick disassembly, thus extending their service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of connection structure technology, and more specifically, to a waist stool buckle structure. Background Technology
[0002] A stroller is a tool designed to facilitate infants' outdoor activities. It is one of babies' favorite modes of transportation and an essential item for mothers when taking their babies shopping. However, the inventors have discovered that the connecting plates of the baby carrier are prone to detachment or are difficult to disassemble.
[0003] In view of the aforementioned shortcomings of the snap-fit structure, and adhering to the spirit of research, innovation, and continuous improvement, the applicant, combined with production practice and using professional and scientific methods, proposes a practical solution and therefore submits this application. Utility Model Content
[0004] The purpose of this utility model is to provide a waist stool buckle structure in response to the existing technical situation. This design enables the waist stool guard plate and the connecting plug plate to be spliced together, which is more convenient and quick.
[0005] A waist stool buckle structure includes: a waist stool guard plate and a connecting insert plate. One end of the connecting insert plate is provided with an insert, and one end of the waist stool guard plate is provided with a connecting buckle. One end of the insert plate is inserted into the slide rail groove through the limiting groove of the connecting buckle. The other end of the insert plate is provided with a limiting part, which is inserted into the limiting groove. One side of the limiting groove is an open end, and the other side of the limiting groove is a locking groove. The locking strip of the limiting part is inserted into the locking groove.
[0006] Specifically, one end of the limiting groove is connected to the slide rail groove, and the other end of the limiting groove extends downward to form a protrusion, which locks the plug-in side.
[0007] Specifically, the slide rail groove has a hole at its end, and the end of the plug extends outward through the hole, making it easy to press the end of the plug so that its limiting part disengages from the limiting groove.
[0008] Specifically, the limiting part has a convex surface on both sides, and the connection between the convex surface and the limiting part is an arc surface. The arc surface design can ensure that the convex strip slides on its upper surface, ensuring that the waist stool guard plate and the connecting insert can be smoothly disengaged and inserted.
[0009] The beneficial effects of this utility model are as follows: the limiting part is inserted into the limiting groove, and the two adopt an interference fit to prevent the plug from falling off easily. The end of the plug protrudes slightly from the hole of the slide rail groove. By pressing the end of the plug, the limiting part can be released from the limitation of the limiting groove, realizing the quick release function of the two. Its structural design is reasonable and improves its service life. Attached Figure Description

[0014] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0015] Please see Figures 1 to 3 As shown, a waist stool buckle structure includes: a waist stool guard plate and a connecting insert. One end of the connecting insert is provided with an insert, and one end of the waist stool guard plate is provided with a connecting buckle. One end of the insert is inserted into the slide rail groove through the limiting groove of the connecting buckle. The other end of the insert is provided with a limiting part, which is inserted into the limiting groove. One side of the limiting groove is an open end, and the other side of the limiting groove is a slot. The locking strip of the limiting part is inserted into the slot.
[0016] In the above solution, one end of the limiting groove is connected to the slide rail groove, and the other end of the limiting groove extends downward to form a protrusion, which engages one side of the connector. The slide rail groove has a hole at its end, and the end of the connector passes through the hole and extends outward. Both sides of the limiting part have a convex surface, and the connection between the convex surface and the limiting part is an arc surface.
[0017] Installation principle: Insert the insert into the slide rail groove along the opening end of the connecting buckle, and insert its limiting part into the limiting groove. The convex strips hold the upper and lower sides of the limiting part, while the convex surface of the limiting part is just inside the limiting groove. The locking strip is also inserted into the locking groove. Through multiple aspects, it restricts the lumbar support plate and the connecting plate from easily separating.
[0018] When disassembly is required, simply press the end of the insert at the hole position. Utilize the elastic deformation of the limiting groove itself to disengage the limiting part from the limiting groove, and the user can then easily pull out the connecting piece.
[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
