Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 - 4As shown in the figure, the present utility model provides a technical solution: a buckle with a locking structure, including: a locking mechanism 1, an inner wall of the locking mechanism 1 is provided with a limiting mechanism 2, the locking mechanism 1 includes a cabinet door 12, an inner wall of the cabinet door 12 is provided with an empty tube 13, an inner wall of the cabinet door 12 is fixedly penetrated through one end of the empty tube 13, an inner wall of the empty tube 13 is provided with a lock block 18, one end of the inner wall of the empty tube 13 is vertically penetrated and connected with one end of the lock block 18, a bottom end of the lock block 18 is provided with an inclined rod 17, one end of the bottom end of the lock block 18 is movably connected with one end of the inclined rod 17, the other end of the inclined rod 17 is provided with a middle plate 16, the other end of the inclined rod 17 is movably connected with an inner wall of one end of the middle plate 16, one side of the middle plate 16 is provided with a connecting rod 15, one side of the middle plate 16 is fixedly connected with one end of the connecting rod 15, one side of the middle plate 16 is provided with a first spring 110, one side of the middle plate 16 is fixedly connected with one end of the first spring 110, the other end of the first spring 110 is fixedly connected with the inner wall of the empty tube 13, the inner wall of the empty tube 13 is provided with a fixing plate 19, the inner wall of the empty tube 13 is fixedly connected with one end of the fixing plate 19, one side of the fixing plate 19 is slidably penetrated through the inner wall of the lock, one end of the connecting rod 15 is provided with a sphere 14, one end of the connecting rod 15 is fixedly connected with one side of the sphere 14, the other side of the sphere 14 is provided with a moving block 111, the other side of the sphere 14 is in sliding contact with one side of the moving block 111, the other end of the moving block 111 is vertically slidably connected with the inner wall of the cabinet door 12, one end of the cabinet door 12 is provided with a cabinet body 11, one end of the cabinet door 12 is movably connected with the inside of the cabinet body 11, one side of the moving block 111 is provided with a handle 113, one side of the moving block 111 is fixedly connected with one end of the handle 113, one end of the lock block 18 is vertically clamped with the inner wall of the cabinet body 11.

[0026] In this embodiment, when the buckle with a locking structure is in use, by pressing the moving block 111, an external force will be exerted on the sphere 14 during the downward movement, forcing the sphere 14 to move from its original position. Since the connecting rod 15 and the middle plate 16 are integrated, therefore, under the influence of the sphere 14, a position change will also occur, and then the inclined rod 17 will change its angle, making the inclination angle gradually smaller. At the same time, the lock block 18 will no longer protrude from the surface of the empty tube 13 and temporarily retract into the inner wall of the empty tube 13. At this time, when the cabinet door 12 and the cabinet body 11 are combined, the empty tube 13 will enter the cabinet body 11 during the re - combination process. When it enters, the external force on the moving block 111 is released, and the first spring 110 will be released to reset all the previous components. At the same time, the lock block 18 will leak out of the empty tube 13 again and be clamped into the cabinet body 11. In this way, after the cabinet door 12 and the cabinet body 11 are combined, the locking can be automatically completed to ensure that the cabinet door 12 can be fully locked when closed, providing safety protection. This design utilizes the angle change of the sphere 14 and the inclined rod 17 to control the state of the lock, enabling the locking action to be automatically completed when the cabinet door 12 is closed without the need to control the locking state with a key.

[0027] Secondly, in order to prevent the locking block 18 from excessively entering the inner wall of the empty tube 13 during the retraction process, a fixing plate 19 is installed inside the locking block 18. Under the action of the fixing plate 19, when retracted to a certain extent, due to the limitation of the fixing plate 19, it can no longer move downward, thereby ensuring the stability of the locking block 18.

[0028] Embodiment 2

[0029] As Figures 1 - 4 shown, the limiting mechanism 2 includes a limiting rod 21. An inner matching plate 23 is arranged on the inner wall of the limiting rod 21. The inner wall of the limiting rod 21 is in sliding contact with one side of the inner matching plate 23. A second spring 22 is arranged on one side of the inner matching plate 23. One side of the inner matching plate 23 is fixedly connected to one end of the second spring 22. The other end of the second spring 22 is fixedly connected to the inner wall of the limiting rod 21. The bottom end of the inner matching plate 23 is fixedly connected to the inner wall of the cabinet door 12. One end of the limiting rod 21 is fitted and clamped with the inner wall of the positioning hole 112.

[0030] In this embodiment, when the moving block 111 moves downward to a certain extent, in order to be able to maintain the position after movement without moving, a positioning hole 112 is opened on one side of the moving block 111. During the downward movement, the limiting rod 21 will always be in contact with one side of the moving block 111. When encountering the positioning hole 112, the second spring 22 will use the inner matching plate 23 as a support point for elastic release, push the limiting rod 21 into the positioning hole 112, and at the same time limit the moving block 111 to ensure that the moving block 111 can be accurately fixed after moving downward to the specified position, avoiding unstable position or movement.

[0031] Working principle:

[0032] As Figures 1 - 4 shown, by pressing the moving block 111, an external force will be exerted on the sphere 14 during the downward movement, forcing the sphere 14 to move from its original position. Since the connecting rod 15 and the middle plate 16 are integrated, therefore, under the influence of the sphere 14, there will also be a position change, and then the inclined rod 17 will change its angle, making the inclination angle gradually become smaller. At the same time, the locking block 18 will no longer protrude from the surface of the empty tube 13 and will temporarily retract into the inner wall of the empty tube 13. At this time, when the cabinet door 12 and the cabinet body 11 are combined, during the process of re - combination, the empty tube 13 will enter the cabinet body 11. When it enters, release the external force on the moving block 111, and the first spring 110 will be released, resetting all the previous components. At the same time, the locking block 18 will leak out of the empty tube 13 again and be clamped into the cabinet body 11, so that after the cabinet door 12 and the cabinet body 11 are combined, the locking can be automatically completed;

[0033] In order to be able to maintain the position after movement without moving, a positioning hole 112 is provided on one side of the moving block 111. During the downward movement, the limiting rod 21 will always contact one side of the moving block 111. When encountering the positioning hole 112, the second spring 22 will use the inner matching plate 23 as a support point for elastic release, push the limiting rod 21 into the positioning hole 112, and at the same time limit the moving block 111 to ensure that the moving block 111 can be accurately fixed after moving down to the specified position.

[0034] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
