[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 6 , the present utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A tape-free, safe and environmentally friendly packaging box, comprising a box body 1 and a box cover 2. Two shells 3 are fixed to the bottom of the box cover 2. Two card slots 4 are opened at the bottom of the shell 3. Both sides of the box body 1 are fixedly connected with clamping blocks 5 that are used in cooperation with the card slots 4. A connecting mechanism is arranged inside the shell 3, and a stabilizing mechanism is arranged on both sides of the box body 1;

[0030] The connecting mechanism includes a linkage block 6 movably arranged inside the shell 3. Connecting blocks 7 are arranged on both sides of the linkage block 6. The connection between the linkage block 6 and the connecting block 7 is hinged by a connecting rod 22. One side of the connecting block 7 is fixedly connected with a moving block 8. One side of the moving block 8 is fixedly connected with a positioning rod 9. A positioning hole 10 is opened on one side of the clamping block 5. One end of the positioning rod 9 penetrates through the shell 3 and extends into the positioning hole 10.

[0031] In this embodiment, it is considered that when placing an item in the packaging box, the box cover 2 needs to be sealed with tape. However, when taking out the item after sealing with tape, the tape needs to be torn off, which will damage the packaging box, resulting in the inability to recycle the packaging box, causing waste, and thus reducing the practicality of the packaging box. Therefore, by setting the connecting mechanism, after placing the item in the box body 1, by moving the pushing block 20 upward, the pushing block 20 drives the driving rod 19 and the linkage block 6 to move upward. The linkage block 6 will drive the connecting rod 22 to adjust around the hinge point. At the same time, the connecting rod 22 will drive the connecting block 7 and the moving block 8 to move along the tracks of the sliding block 16 and the sliding groove 17. The moving block 8 will drive the positioning rod 9 to retract into the shell 3. Then, align the positions of the clamping block 5 and the card slot 4, and clamp the box cover 2 on the top of the box body 1. At the same time, make the clamping block 5 enter the card slot 4. Release the pushing block 20, and the pulling force generated by the tension spring 18 will drive the moving block 8 and the positioning rod 9 to move, so that the positioning rod 9 enters the positioning hole 10, and the connection between the box body 1 and the box cover 2 can be completed. When taking out the item, following the above steps, move the pushing block 20 upward to make the positioning rod 9 leave the positioning hole 10, which will not damage the box body 1 and the box cover 2 and can be recycled, making the packaging box safer and more environmentally friendly;

[0032] It solves the problem that when placing an item in the packaging box, the box cover 2 needs to be sealed with tape. However, when taking out the item after sealing with tape, the tape needs to be torn off, which will damage the packaging box, resulting in the inability to recycle the packaging box, causing waste, and thus reducing the practicality of the packaging box.

[0033] Sliding blocks 16 are fixedly connected to both the top and bottom of the moving block 8. Sliding grooves 17 that are used in cooperation with the sliding blocks 16 are opened on the inner wall of the shell 3.

[0034] In this embodiment, by providing the sliding block 16 and the sliding groove 17, the trajectories of the moving block 8, the connecting block 7 and the positioning rod 9 can be restricted. When the connecting rod 22 drives the connecting block 7 to move, mechanisms such as the moving block 8 can only slide along the trajectories of the sliding block 16 and the sliding groove 17, while improving the smoothness during the sliding process.

[0035] One side of the linkage block 6 is fixedly connected with a tension spring 18, and one end of the tension spring 18 is fixedly connected with the inner wall of the housing 3.

[0036] In this embodiment, by providing the tension spring 18, when the user releases the pushing block 20, the pulling force generated by the tension spring 18 will drive structures such as the moving block 8 and the positioning rod 9 to move, so that the positioning rod 9 enters the positioning hole 10 to play a reset role.

[0037] One side of the linkage block 6 is fixedly connected with a driving rod 19. One end of the driving rod 19 penetrates to one side of the housing 3 and is fixedly connected with a pushing block 20. A driving groove 21 matching with the driving rod 19 is provided on one side of the housing 3.

[0038] In this embodiment, by providing the driving rod 19, the pushing block 20 and the driving groove 21, the pushing block 20 can be moved to drive the driving rod 19 and the linkage block 6 to move, so as to cooperate with the connecting mechanism to play a transmission role. At the same time, the driving groove 21 can also play a role in restricting the moving trajectory.

[0039] Embodiment Two:

[0040] On the basis of Embodiment One, in this embodiment, the connecting mechanism can connect the box body 1 and the box cover 2. However, considering that it is difficult to ensure the stability of the box cover 2 and the box body 1 during transportation only by connecting and fixing the two sides of the box body 1 and the box cover 2 through the connecting mechanism, the stability mechanism in this application includes stabilizing blocks 11 fixedly connected to both sides of the box body 1. Elastic pieces 12 are fixedly connected to both sides of the stabilizing blocks 11. A spherical block 13 is fixedly connected to one side of the elastic piece 12. A stabilizing groove 14 matching with the stabilizing block 11 is provided on the inner wall of the box cover 2, and a matching groove 15 matching with the spherical block 13 is provided on the inner wall of the stabilizing groove 14.

[0041] This embodiment considers that it is difficult to ensure the stability of the box cover 2 and the box body 1 during transportation only by connecting and fixing the two sides of the box body 1 and the box cover 2 through the connecting mechanism. Therefore, by providing the stability mechanism, during the process of the box cover 2 being stuck on the top of the box body 1, the inner wall of the stabilizing groove 14 will contact the arc part of the elastic piece 12, so that the spring is in a compressed state and enters the stabilizing groove 14 together with the stabilizing block 11. After reaching the appropriate position, the elastic force generated by the elastic piece 12 will push the spherical block 13 into the corresponding matching groove 15 to further improve the connection stability between the box body 1 and the box cover 2;

[0042] The problem that it is difficult to ensure the stability of the box cover 2 and the box body 1 during transportation by only connecting and fixing both sides of the box body 1 and the box cover 2 through the connecting mechanism is solved;

[0043] It should be noted that when a pulling force is applied upward to the box cover 2 to take out the box cover 2, the stable groove 14 will squeeze the elastic piece 12 again to make the elastic piece 12 contract, and only a certain force needs to be applied to open the box cover 2.

[0044] The shape of the elastic piece 12 is arc-shaped.

[0045] In this embodiment, the shape of the elastic piece 12 is set to be arc-shaped, so that the elastic piece 12 can contact the inner wall of the stable groove 14, causing the elastic piece 12 to deform, so as to easily move the stable block 11 into the stable groove 14.

[0046] The number of the stable blocks 11 is several, and the distance between two stable blocks 11 is 10 cm.

[0047] In this embodiment, by setting a plurality of stable blocks, the stability of the connection between the box cover 2 and the box body 1 can be effectively improved. At the same time, the distance of 10 cm between the stable blocks 11 is the best distance through testing.

[0048] Working principle: After placing the items in the box body 1, by moving the push block 20 upward, the push block 20 drives the drive rod 19 and the linkage block 6 to move upward. The linkage block 6 will drive the connecting rod 22 to adjust around the hinge point. At the same time, the connecting rod 22 will drive the connecting block 7 and the moving block 8 to move along the tracks of the sliding block 16 and the sliding groove 17. The moving block 8 will drive the positioning rod 9 to retract into the housing 3. Then, align the position of the clamping block 5 and the clamping groove 4, and clamp the box cover 2 on the top of the box body 1. At the same time, make the clamping block 5 enter the inside of the clamping groove 4. Release the push block 20, and the pulling force generated by the tension spring 18 will drive the moving block 8 and the positioning rod 9 to move, so that the positioning rod 9 enters the positioning hole 10, and the connection between the box body 1 and the box cover 2 can be completed. When the items need to be taken out, follow the above steps and move the push block 20 upward to make the positioning rod 9 leave the positioning hole 10, which will not cause damage to the box body 1 and the box cover 2 and can be recycled, making the packaging box safer and more environmentally friendly;

[0049] During the process of clamping the box cover 2 on the top of the box body 1, the inner wall of the stable groove 14 will contact the arc-shaped part of the elastic piece 12, making the spring in a compressed state and entering the stable groove 14 together with the stable block 11. Then, after reaching the appropriate position, the elastic force generated by the elastic piece 12 will push the spherical block 13 into the corresponding mating groove 15, further improving the stability of the connection between the box body 1 and the box cover 2.

[0050] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
