[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Figures 1 to 6 The structure of a novel buckle according to one embodiment of the present utility model is schematically shown.

[0023] like Figures 1 to 6 As shown, a new buckle includes a back plate 1, a base plate 2 and a buckle plate 3.

[0024] Figures 1 to 6 In the embodiment, the lower end of the back plate 1 is rotatably connected to the lower end of the base plate 2, the upper end of the pinch plate 3 can be rotatably connected to the middle position of the base plate 2, and the upper end of the pinch plate 3 can move along the base plate 2. A spring 4 can be installed at the connection between the pinch plate 3 and the base plate 2. The upper end of the spring 4 can resist the pinch plate 3 so that the pinch plate 3 will not move along the base plate 2 by itself without the action of external force. Of course, if Figure 1 and Figure 2 As shown, when a downward external force is applied to the pinch plate 3, the pinch plate 3 will move downward, and the spring 4 will be compressed.

[0025] Specifically, in this embodiment, the lower end of the back panel 1 is rotatably connected to the lower end of the base panel 2 via a first rivet 5. Therefore, during use, the base panel 2 can rotate around the lower end of the back panel 1. The upper end of the pinch plate 3 is connected to a second rivet 6. The upper end of the pinch plate 3 is rotatably connected to the base panel 2 via the second rivet 6. A first slide groove 21 is integrally formed on the base panel 2. Therefore, the second rivet 6 can also pass through the first slide groove 21. The second rivet 6 can move along the first slide groove 21, so that the upper end of the pinch plate 3 can move along the first slide groove 21. Therefore, the pinch plate 3 can be both rotatably connected to the base panel 2 via the second rivet 6 and can slide relative to the base panel 2 via the second rivet 6.

[0026] Since the second rivet 6 is fixed to the gusset plate 3, Figure 6 As can be seen in the figure, the upper end of the spring 4 can press against the second rivet 6 to press against the gusset plate 3. The spring 4 is in a compressed state. In the absence of external force, the upper end of the spring 4 can keep the gusset plate 3 at the top.

[0027] like Figure 5 As shown, the present invention further includes a connecting frame 7, which is formed with a receiving cavity, in which the spring 4 is installed. The lower end of the spring 4 is fixedly mounted on the bottom inner wall of the connecting frame 7, and the connecting frame 7 is located in the space formed by the back plate 1 and the base plate 2. The lower end of the connecting frame 7 is rotatably connected to the first rivet 5, and the second rivet 6 passes through the upper end of the connecting frame 7. The upper end of the connecting frame 7 is integrally formed with a second slide groove 73, so that the second rivet 6 can also move along the second slide groove 73. The connecting frame 7 serves to accommodate the spring 4, and the accommodating spring 4 can be fixed to the connecting frame 7.

[0028] like Figure 5 As shown, in this embodiment, two lugs 71 are formed on the lower end of the connecting frame 7, and the first rivet 5 is rotatably connected to the lugs 71. Therefore, when the first rivet 5 rotates, the connecting frame 7 will not rotate with it.

[0029] In this embodiment, if Figure 6 As shown, there are three springs 4. A connecting plate 72 is also provided at the upper end of the connecting frame 7. The upper ends of the three springs 4 rest against the connecting plate 72, which in turn rests against the second rivet 6. When the springs 4 are compressed, in the absence of external forces, the upper ends of the springs 4 can rest against the pinch plate 3, keeping the pinch plate 3 always at the top. When an external force pulls the pinch plate 3 downward, the second rivet 6 connected to the pinch plate 3 is also pulled downward, driving the connecting plate 72 downward. This further compresses the three springs 4.

[0030] In this embodiment, a sub-button 8 is further included for use with the buckle plate 3 . A groove 31 is formed at the lower end of the inner wall of the buckle plate 3 , and the sub-button 8 can be stuck in the groove 31 .

[0031] The following is a detailed description of the overall working method of the utility model: 1. Install the utility model, rotate as shown in the figure: Figure 1 The base plate 2 and the buckle plate 3 shown in the figure are used to fix the back plate 1 on the box cover, and then the buckle 8 is fixed on the box body. The base plate 2 is rotated and the upper end cover of the base plate 2 is closed to the back plate 1 to form a Figure 1 As shown in the state, the gusset plate 3 is then pulled downward with force, so that the gusset plate 3 moves downward. Accordingly, the second rivet 6 connected to the gusset plate 3 is also pulled downward, and the second rivet 6 drives the connecting plate 72 to move downward. The connecting plate 72 further compresses the three springs 4, and then the gusset plate 3 is rotated to the state shown in the state. Figure 1 In the state shown, the buckle plate 3 is snapped into the sub-buckle 8. At this time, the three springs 4 will tightly press against the upper end of the buckle plate 3, so that the buckle plate 3 will not detach from the sub-buckle 8 by itself.

[0032] Since the back panel 1, the base panel 2 and the buckle plate 3 can form a whole, the whole formed by the back panel 1, the base panel 2 and the buckle plate 3 (equivalent to the female buckle) can be installed on the box cover, and the sub-buckle 8 can be installed on the box body (of course, the sub-buckle 8 can also be installed on the box cover according to actual conditions, and vice versa, the female buckle is installed on the box body). A spring 4 is installed at the connection between the buckle plate 3 and the base panel 2, and a second rivet 6 is connected to the upper end of the buckle plate 3. The buckle plate 3 can be rotatably connected to the base panel 2 through the second rivet 6, and the buckle plate 3 can also move because the upper end of the spring 4 can rest on the second rivet 6.

[0033] When the present invention is to be used, the buckle plate 3 is pulled with a certain force, so that the second rivet 6 and the buckle plate 3 move, the spring 4 is compressed, and the buckle plate 3 is clamped on the buckle 8. At this time, the box cover and the box body can be closed together. Since the spring 4 can be compressed, the buckle plate 3 and the buckle 8 are elastically connected, and the installation is more labor-saving. The spring 4 will press tightly against the upper end of the buckle plate 3, and the buckle plate 3 and the buckle 8 can be fastened more tightly.

[0034] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
