[0022] The following description is only a preferred embodiment of this utility model and does not limit the scope of protection of this utility model.

[0023] Example 1

[0024] A foldable and reusable honeycomb reinforced cardboard box 1, such as Figures 1-8 As shown, it includes a cardboard box 1, side covers 2, and a cover plate 3; the cardboard box 1 has two side covers 2 that are symmetrically distributed on the upper and lower sides; the cardboard box 1 has a cover plate 3 on the upper and lower sides.

[0025] It also includes connecting rods 4, inserts 5, reinforcing plates 6, and fixing rods 7; four connecting rods 4 are slidably connected to the inside of the carton 1 in a matrix arrangement; at least twelve inserts 5 are fixedly connected to each connecting rod 4 in a vertical arrangement; each connecting rod 4 is rotatably connected to the same number of reinforcing plates 6 as the inserts 5, and the reinforcing plates 6 are fixedly connected to the carton 1, and adjacent reinforcing plates 6 are staggered; each reinforcing plate 6 has a slot 6a, and the slot 6a cooperates with the inserts 5; a fixing rod 7 is fixedly connected between each pair of adjacent connecting rods 4.

[0026] It also includes flexible strips 8; a flexible strip 8 is embedded in each of the four corners of the carton 1.

[0027] The flexible strip 8 is designed to be wavy, so that when the carton 1 is folded, the wavy flexible strip 8 can better absorb stress.

[0028] Also comprises a connecting block 21, spring 22, clamping block 23 and fixed seat 24; each cover plate 3 is installed with a connecting block 21; each connecting block 21 is fixedly connected with two springs 22 which are symmetrically distributed left and right; each spring 22 is fixedly connected with a clamping block 23, and the clamping block 23 is in sliding connection with the connecting block 21; the front side of the carton 1 is provided with two fixed seats 24 which are symmetrically distributed up and down.

[0029] When using the foldable and reusable honeycomb reinforced carton 1, first, the staff places the articles into the carton 1, then bends the side cover 2 on the carton 1 by 90 degrees, and then bends the cover plate 3 on the carton 1 by 90 degrees as well. The connecting block 21 and the parts connected therewith will move synchronously with the cover plate 3. During this process, the staff will push the two clamping blocks 23 to move towards each other on the connecting block 21, and the spring 22 is compressed. Then, the connecting block 21 will contact the fixed seat 24. Next, the staff will release the clamping block 23, and the spring 22 will change from the compressed state to the normal state. During the change of the spring 22, the two clamping blocks 23 will move away from each other and return to the original position. Then, the clamping block 23 will be inserted into the lock hole on the fixed seat 24. Thus, the locking of the cover plate 3 is completed, as shown in FIG. 6, so that the carton 1 and the cover plate 3 are connected together through the cooperation of the connecting block 21, the spring 22, the clamping block 23 and the fixed seat 24, without the need for transparent glue to connect them together. It is convenient to use and easy to disassemble. At the same time, it also avoids the problem in the prior art that the existing carton 1 is usually connected with the cover plate 3 together through transparent glue when sealing, and when disassembling, the transparent glue needs to be torn off, which is easy to tear the carton 1, thereby affecting the reuse of the carton 1. Figure 7

[0030] Then, during the transportation of the carton 1, since the plug-in block 5 is inserted into the clamping groove 6a, when the edge area of the four corners of the carton 1 is extruded or collided by external force, the reinforcing plate 6 will not rotate on the connecting rod 4 due to the impact force, so that the reinforcing plate 6 can provide a good rigid support for the carton 1, thereby avoiding the problem that the side of the carton 1 will be damaged or deformed when the side of the carton 1 is impacted by external force, thereby affecting the subsequent use of the carton 1.

[0031] At the same time, the reinforcing plate 6 also has the effect of resisting pressure and fixing the four corners of the carton 1, thereby avoiding the problem that after the carton 1 is used and folded for many times, the folding part of the four corners of the carton 1 is easy to produce material fatigue, so that the pressure resistance and rigidity of the carton 1 are reduced, and then the folding part, the edge or the joint part of the carton 1 may be worn, torn or other problems due to friction or stress concentration during the transportation, thereby shortening the service life of the carton 1.

[0032] ​When the carton 1 needs to be reused, in order to save space and better transport to the destination, the staff will fold the carton 1, that is, the carton 1 is not in an unfolded state, in the process, the staff will first push the two clamping blocks 23 to move towards each other on the connecting block 21, the spring 22 is compressed, and then the clamping block 23 will exit from the lock hole on the fixed seat 24, so that the connection between the carton 1 and the cover plate 3 is released, then the staff pulls the fixed rod 7 upwards, the connecting rod 4 and the plug block 5 will follow the fixed rod 7 and move upwards synchronously, and then the plug block 5 will be separated from the clamping groove 6a, and then the staff will fold the carton 1, in the process of folding the carton 1, the carton 1 will drive the reinforcing plate 6 to rotate on the connecting rod 4, at the same time, since the flexible strip 8 is arranged in a wave shape, when the carton 1 is folded, the stress is absorbed through the multi-stage bending deformation of the flexible strip 8, thereby reducing material fatigue, thereby prolonging the folding life of the carton 1, and enhancing the stability of the structure.

[0033] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
