[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 , is an elastic self-locking buckle structure of an embodiment of the utility model, including a first buckle body 10, a second buckle body 20 matching the first buckle body 10, and an adapter assembly 30 for connecting the first buckle body 10 and the second buckle body 20; the adapter assembly 30 is located inside the first buckle body 10.

[0029] In this embodiment, the first buckle body 10 is substantially C-shaped or U-shaped, a receiving cavity 11 is provided at one end of the first buckle body 10 , and a positioning cavity 12 is provided at the other end of the first buckle body 10 .

[0030] In this embodiment, the second buckle body 20 is generally C-shaped or U-shaped, and the opposite ends of the second buckle body 20 are matched and correspondingly fitted with the opposite ends of the first buckle body 10 to form a closed annular structure. One end of the second buckle body 20 is provided with an inserting cavity, and the other end of the second buckle body 20 is provided with a positioning column 21 protruding outward, and the positioning column 21 is used to be correspondingly inserted into the interior of the positioning cavity 12.

[0031] The adapter assembly 30 includes a piston rod 31 slidably mounted inside the accommodating chamber 11, a spring 32 coaxially sleeved on the piston rod 31, and a stop ring 33 mounted at the open end of the accommodating chamber 11; the rod body of the piston rod 31 passes through the stop ring 33 and is connected to the inside of the plug-in chamber to achieve the connection between the first buckle body 10 and the second buckle body 20. One end of the spring 32 abuts against the plug of the piston rod 31, and the other end of the spring 32 abuts against the stop ring 33 to drive the second buckle body 20 to automatically buckle onto the first buckle body 10, achieving self-locking, so that the first buckle body 10 and the second buckle body 20 are not easily separated, greatly improving the safety and reliability of the storage of items. When unlocking, the first buckle body 10 and the second buckle body 20 are driven away from each other by applying external force. At this time, the piston rod 31 performs piston motion inside the accommodating cavity 11, the spring 32 is compressed, and the positioning column 21 is away from the positioning cavity 12, and an opening is generated between the first buckle body 10 and the second buckle body 20, which is convenient for users to take out items between the first buckle body 10 and the second buckle body 20. Then, the external force is removed, and the spring 32 returns to its original state, driving the first buckle body 10 and the second buckle body 20 to move closer to each other and lock. This structure uses the elastic force of the spring 32 to create an opening between the first buckle body 10 and the second buckle body 20, and a new self-locking buckle can be replaced without a complicated disassembly process, effectively improving the convenience of use and user experience.

[0032] In this embodiment, the diameter of the plug head of the piston rod 31 is equal to the inner diameter of the accommodating chamber 11, and the diameter of the rod body of the piston rod 31 is equal to the inner diameter of the limiting ring 33, which can greatly improve the smoothness and stability of the movement of the piston rod 31 inside the accommodating chamber 11.

[0033] In this embodiment, the piston rod 31 and the accommodating chamber 11 are coaxially installed, so that the piston rod 31 and the first buckle body 10 can rotate relative to each other, and then the second buckle body 20 and the first buckle body 10 can rotate relative to each other during use, effectively improving the convenience of use and user experience.

[0034] The above-mentioned elastic self-locking buckle structure has a simple structure and is easy to use. One end of the second buckle body 20 is connected to the inside of the first buckle body 10 through the piston rod 31 and the spring 32. The elastic force of the spring 32 is used to drive the second buckle body 20 and the first buckle body 10 to achieve automatic locking. There is no need for a complicated disassembly process, which effectively improves the convenience of use and user experience.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
