[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0028] Embodiment 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the present utility model provides a suitcase with a buckle, including a suitcase main body 1, and a locking structure 2 is fixedly installed at the opening of the suitcase main body 1;

[0029] The locking structure 2 includes a first fixing rod 21, a second fixing rod 22 and a docking rod 25. The docking rod 25 is rotatably installed on the lower surface of the first fixing rod 21. A docking block 26 is fixedly installed on the upper surface of the second fixing rod 22. A clamping block 28 is movably connected inside the docking block 26 through a spring. An engaging frame 27 is fixedly installed on the outer wall of the docking rod 25. A convex block 29 is fixedly installed on the top of the clamping block 28. The convex block 29 is inserted into the inside of the engaging frame 27.

[0030] A through hole 210 is provided at the junction of the engaging frame 27 and the convex block 29. The engaging frame 27 overlaps on the top of the docking block 26. A positioning notch 213 is provided at the junction of the docking block 26 and the engaging frame 27. The positioning notch 213 is located at a corner of the docking block 26. A cavity 214 is provided inside the docking block 26. The clamping block 28 is located inside the cavity 214. The first fixing rod 21 is fixedly installed on the outer wall of one of the boxes of the suitcase main body 1. The second fixing rod 22 is fixedly installed on the outer wall of the other box of the suitcase main body 1.

[0031] Next, the specific settings and functions of this embodiment will be described in detail. The locking structure 2 is fixedly installed at the opening of the suitcase main body 1. Among them, the first fixing rod 21 is fixedly installed on the outer wall of one of the boxes of the suitcase main body 1, and the second fixing rod 22 is fixedly installed on the outer wall of the other box of the suitcase main body 1. When closing the suitcase main body 1, after the two boxes are spliced together, the zipper is normally zipped up. When splicing, the docking rod 25 will be brought above the second fixing rod 22.

[0032] Subsequently, press the clamping block 28 and rotate the docking rod 25 so that one end of it enters the cavity 214 of the docking block 26 until the engaging frame 27 on the outer wall of the docking rod 25 is spliced to the positioning notch 213. Then release the clamping block 28. Under the spring's rebound, the clamping block 28 is pushed upward, so that the convex block 29 on the top of the clamping block 28 is inserted into the through hole 210 of the engaging frame 27, completing the locking of the engaging frame 27. At this time, the docking rod 25 cannot rotate because the engaging frame 27 on its outer wall is fixed by the convex block 29, which makes the docking rod 25 unable to rotate horizontally. Moreover, since the docking rod 25 is inside the docking block 26, its longitudinal movement is also blocked, making the suitcase main body 1 unable to be opened.

[0033] By additionally providing a snap-type locking structure 2 at the zipper of the suitcase main body 1, when closing the suitcase main body 1, the snap-type structure can further improve the security of the suitcase main body 1. The structure composed of the first fixing rod 21, the second fixing rod 22 and the docking rod 25 has strong stability, is more safe and durable, and can withstand strong impacts during the process of moving the suitcase main body 1.

[0034] Embodiment 2: As Figure 3 andFigure 4 As shown, a clamping groove 211 is formed inside the clamping block 28. The clamping block 28 is slidably connected to the docking block 26 through the clamping groove 211. A limiting piece 212 is fixedly installed at the top of the clamping block 28. The limiting piece 212 is lapped at one end of the connection frame 27. A connection block 24 is fixedly installed on the lower surface of the first fixing rod 21. One end of the docking rod 25 is rotatably connected inside the connection block 24. The docking rod 25 is located at both ends of the first fixing rod 21. The docking block 26 is located at both ends of the second fixing rod 22. A protection rod 23 is fixedly installed on the lower surface of the first fixing rod 21. The protection rod 23 is inserted into the second fixing rod 22.

[0035] The effect achieved by the entire embodiment is that the clamping groove 211 in the clamping block 28 is used to splice the docking block 26. When the clamping block 28 is pressed down, the clamping groove 211 can determine the moving route of the clamping block 28. When the spring rebounds, the clamping groove 211 can determine the moving range of the clamping block 28, which can not only ensure that the convex block 29 can be inserted into the through hole 210, but also ensure the stability of the clamping block 28 itself in the docking block 26, preventing it from shaking left and right. The limiting piece 212 on the docking block 26 is used to fit one end of the connection frame 27, playing an auxiliary stabilizing role;

[0036] The connection block 24 on the lower surface of the first fixing rod 21 is used to connect the docking rod 25. As Figure 4 shown, only one side of the corner of the docking rod 25 is arc-shaped, so that the docking rod 25 can only rotate on the side with a rounded corner. After determining the position of the docking rod 25, the protection rod 23 can also cover the opening of the main body 1 of the suitcase synchronously to play a role in protecting the opening. The cooperation of the zipper structure and the buckle structure can greatly improve the safety of the main body 1 of the suitcase.

[0037] The usage method and working principle of this device: When closing the main body 1 of the suitcase, first splice the two boxes together, and then normally zip up. When splicing, the docking rod 25 will be brought above the second fixing rod 22. At this time, first press down the clamping block 28, and then rotate the docking rod 25 to turn one end of it into the cavity 214 of the docking block 26. At this time, the connection frame 27 on the outer wall of the docking rod 25 will also be spliced to the positioning notch 213;

[0038] Then release the clamping block 28. Under the rebound of the spring, the clamping block 28 is pushed up, so that the convex block 29 at the top of the clamping block 28 is inserted into the through hole 210 of the connection frame 27, completing the locking of the connection frame 27. At this time, the docking rod 25 cannot rotate, and the main body 1 of the suitcase cannot be opened. The moving range and route of the clamping block 28 are restricted by the clamping groove 211;

[0039] The docking rod 25 has an arc-shaped corner on only one side, so that the docking rod 25 can only rotate on the side with a rounded corner. After determining the position of the docking rod 25, the protection rod 23 can also cover the opening of the main body 1 of the suitcase synchronously, so as to protect the opening. Using it in cooperation with the original zipper structure can greatly improve the safety of the main body 1 of the suitcase.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit 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 content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
