[0045] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a folding packaging box with a locking structure.

[0046] A folding packaging box with a locking structure includes a rectangular frame 1 and a first fold line 2, the first fold line 2 being disposed on the rectangular frame 1, and further includes:

[0047] Reference Figures 1 to 6 In a preferred embodiment, the rectangular frame 1 has four first positioning slots 19 for providing space for the first positioning plate 16 to move, and a second positioning slot 20 for providing space for the second positioning plate 17 to move.

[0048] The sealing folding plate 3 is fixedly installed on the rectangular frame 1;

[0049] A trapezoidal insert 4 is mounted on the sealing folding plate 3 and is fixedly connected to the sealing folding plate 3.

[0050] The sealing folding plate 3 is provided with four first positioning plates 16, which are fixedly connected to the sealing folding plate 3; a second positioning plate 17 is fixedly provided on the sealing folding plate 3.

[0051] The sealing fold plate 3 is provided with three second fold lines 18, which are used to enable the sealing fold plate 3 to be folded in segments along the outline of the rectangular frame 1, thereby adapting to the structural shape of the rectangular frame 1 and achieving a tight fit.

[0052] Two slots 5 are provided, and the two slots 5 are symmetrically opened on the trapezoidal insert plate 4;

[0053] Insert box 6 is fixedly mounted on rectangular frame 1;

[0054] During operation, the sealing folding plate 3 is manually folded along the second folding line 18. During the folding process, the first positioning plate 16 is inserted into the first positioning groove 19, and the second positioning plate 17 is inserted into the second positioning groove 20 to reinforce the connection between the sealing folding plate 3 and the rectangular frame 1. Then, the rectangular insert plate is inserted into the insert box 6. The trapezoidal insert plate 4 drives the two fixed clamping plates 7 to move away from each other through the inclined surface, thereby squeezing the elastic mechanism.

[0055] Reference Figure 1 , Figure 3 and Figure 6 In a preferred embodiment, two elastic mechanisms are provided, and the two elastic mechanisms are disposed within the insert 6; the elastic mechanisms include:

[0056] Two positioning springs 9 are provided, and the two positioning springs 9 are set inside the insertion box 6. One end of the positioning spring 9 is fixedly connected to the insertion box 6.

[0057] Two sliding plates 10 are provided. The two sliding plates 10 are set in the insertion box 6, fixedly connected to the fixed card plate 7, and fixedly connected to the other end of the positioning spring 9.

[0058] There are two fixed plates 7, which are set on the elastic mechanism;

[0059] Two push plates 8 are provided, and the two push plates 8 are fixedly mounted on the fixed card plate 7 and slidably connected to the insertion box 6.

[0060] Two guiding mechanisms are provided, symmetrically arranged on the insertion box 6; the guiding mechanisms include:

[0061] Two guide rods 11 are provided, and the two guide rods 11 are symmetrically fixed in the insertion box 6 and slidably connected to the sliding plate 10.

[0062] Two limiting plates 12 are provided, and the two limiting plates 12 are fixedly installed on the guide rod 11 to limit the extreme position of the sliding plate 10 moving along one end direction.

[0063] Two symmetrical moving slots 21 are provided on the insert box 6 to limit the moving trajectory of the push plate 8.

[0064] During operation, the fixed plates 7 move away from each other, causing the two sliding plates 10 to move away from each other along the guide rod 11. The sliding plates 10 compress the positioning spring 9, storing elastic potential energy. When the fixed plates 7 move to the slot 5 on the trapezoidal insert 4, the positioning spring 9 releases its elastic potential energy, causing the sliding plates 10 to move. The sliding plates 10 then move the fixed plates 7 closer together and insert them into the slot 5, thus fixing and locking the trapezoidal insert 4. When it is necessary to open, the two push plates 8 are pushed away from each other. The push plates 8 cause the two fixed plates 7 to move away from each other and out of the slot 5, releasing the fixation of the trapezoidal insert 4. At this time, the ejection mechanism ejects the trapezoidal insert 4 out of the insert box 6.

[0065] Reference Figure 3 and Figure 6 In a preferred embodiment, an ejection mechanism is disposed within the insert box 6 to eject the trapezoidal insert plate 4 from the insert box 6. The ejection mechanism includes:

[0066] An ejector spring 13 is installed inside the insert box 6, and one end of the ejector spring 13 is fixedly connected to the insert box 6.

[0067] Ejector plate 14 is mounted on ejector spring 13 and is fixedly connected to the other end of ejector spring 13.

[0068] The limiting hollow column 15 is fixedly installed on the insertion box 6 to prevent the ejector spring 13 from shifting or twisting during the extension and retraction process.

[0069] During the locking process, the trapezoidal insert plate 4 moves closer to the ejector plate 14 and pushes the ejector plate 14 to move. The ejector plate 14 compresses the ejector spring 13 and causes the ejector spring 13 to store elastic potential energy. When it is necessary to open the box, the ejector spring 13 releases the elastic potential energy to drive the ejector plate 14 to move. The ejector plate 14 pushes the trapezoidal insert plate 4 out of the insert box 6.

[0070] Working principle: The sealing folding plate 3 is manually folded along the second folding line 18. During the folding process, the first positioning plate 16 is inserted into the first positioning groove 19, and the second positioning plate 17 is inserted into the second positioning groove 20, reinforcing the connection between the sealing folding plate 3 and the rectangular frame 1. Then, the rectangular insert plate is inserted into the insert box 6. The trapezoidal insert plate 4 drives the two fixed clamping plates 7 to move away from each other through the inclined surface. The moving away of the fixed clamping plates 7 drives the two sliding plates 10 to move away from each other along the guide rod 11. The sliding plates 10 compress the positioning spring 9, allowing it to store elastic potential energy. When the fixed clamping plate 7 moves to the groove 5 on the trapezoidal insert plate 4, the positioning is completed. Spring 9 releases its elastic potential energy, causing sliding plate 10 to move. Sliding plate 10 causes fixed plates 7 to move closer together and insert into slot 5, thus fixing and locking trapezoidal insert 4. During the fixing and locking process, trapezoidal insert 4 moves closer to ejector plate 14 and pushes ejector plate 14 to move. Ejector plate 14 compresses ejector spring 13 and causes ejector spring 13 to store elastic potential energy. When it is necessary to open, push two push plates 8 to move away from each other. Push plates 8 cause two fixed plates 7 to move away from each other and move out of slot 5, releasing the fixation of trapezoidal insert 4. At this time, ejector spring 13 releases its elastic potential energy, causing ejector plate 14 to move. Ejector plate 14 pushes trapezoidal insert 4 out of insert box 6.

[0071] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
