Specific embodiments

[0022] 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. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-load carton, including a carton body 1, a U-shaped bracket 2 is provided on the inner wall of the carton body 1. In order to facilitate increasing the load-bearing capacity of the carton body 1 and being able to adapt to objects of different sizes for loading, a plurality of support partitions 3 are slidably installed on the U-shaped bracket 2 arranged on the carton body 1. After the U-shaped bracket 2 is placed into the carton body 1, it can effectively support the bottom side and the inner wall of the carton body 1. A locking structure is installed inside each of the plurality of support partitions 3, and a driving structure and a retaining structure are installed on the locking structure;

[0024] The locking structure includes an installation cavity 4. An installation cavity 4 is opened on the support partition 3. Two transmission rods 41 are slidably installed on the bottom inner wall of the installation cavity 4. T-shaped blocks 42 are installed on both of the two transmission rods 41. Friction pads 43 are installed on both of the two T-shaped blocks 42. Chutes 44 are opened at the inner wall positions of both ends of the U-shaped bracket 2. The two friction pads 43 are respectively slidably installed in the chutes 44 and are in contact with the inner wall of the chutes 44. A limit groove 46 is opened on the bottom inner wall of the installation cavity 4. A limit block 45 is slidably installed on the inner wall of the limit groove 46. The limit block 45 is installed on the bottom side of the transmission rod 41. By moving the support partition 3 on the U-shaped bracket 2, not only can the space inside the carton body 1 be stratified to facilitate placing objects of different sizes, but also the vertical placement of the support partition 3 can play a role in supporting the carton body 1 in the vertical direction.

[0025] In order to facilitate the convenient movement and fixation of the support partition plate 3 on the U-shaped bracket 2, a driving structure is arranged on the support partition plate 3, which specifically includes a fixed block 5. The fixed block 5 is installed on the inner wall of the installation cavity 4. A driving rod 51 is slidably installed on the fixed block 5. A pressing plate 54 is installed at the top end of the driving rod 51. A positioning hole 53 is formed on the upper surface of the support partition plate 3. The pressing plate 54 is slidably installed in the positioning hole 53. A transfer plate 55 is installed on the bottom side of the driving rod 51. Two connecting rods 56 are rotatably installed on the bottom side of the transfer plate 55. The other ends of the two connecting rods 56 are respectively rotatably installed on the two transmission rods 41. A return spring 52 is sleeved on the driving rod 51. One end of the return spring 52 is installed on the fixed block 5, and the other end of the return spring 52 is installed on the pressing plate 54. By driving the driving rod 51 on the fixed block 5 to move downward with the pressing plate 54, the driving rod 51 drives the transfer plate 55 to move. The transfer plate 55 drives the connecting rod 56 to rotate. The connecting rod 56 drives the transmission rod 41 to move backward. The movement of the transmission rod 41 drives the guide rod 61 on the positioning block 6 to move. The guide rod 61 drives the retention spring 62 to be compressed. At the same time, the transmission rod 41 drives the T-shaped block 42 to move towards the middle. The T-shaped block 42 drives the friction pad 43 to disengage from the inner wall of the chute 44, so that the support partition plate 3 can be conveniently moved to an appropriate position. Then, the pressing plate 54 is released. The restoring force of the return spring 52 is used to drive the friction pad 43 to move forward quickly and press against the inner wall of the chute 44. At the same time, by using the characteristics of the friction pad 43, it can effectively prevent the friction pad 43 from slipping off the chute 44 when the support partition plate 3 is in use.

[0026] The working principle is as follows: When the paper box body 1 is in use, in order to effectively increase the paper box body 1 when loading items and avoid the situation of the paper box body 1 collapsing, a U-shaped bracket 2 is provided on the inner wall of the paper box body 1. The setting of the U-shaped bracket 2 can effectively support the bottom side and the inner wall of the paper box body 1. Then, in order to enable the paper box body 1 to adapt to different sizes of items when loading items, when the support partition 3 needs to be moved, only need to manually press the pressing plate 54. The pressing plate 54 drives the return spring 52 to be compressed. At the same time, the driving rod 51 on the fixed block 5 is driven to move downward by the pressing plate 54. The driving rod 51 drives the adapter plate 55 to move. The adapter plate 55 drives the connecting rod 56 to rotate. The connecting rod 56 drives the transmission rod 41 to move backward. The transmission rod 41 drives the guide rod 61 on the positioning block 6 to move. The guide rod 61 drives the retaining spring 62 to be compressed. At the same time, the transmission rod 41 drives the T-shaped block 42 to move towards the middle. The T-shaped block 42 drives the friction pad 43 to disengage from the inner wall of the chute 44. Thus, the support partition 3 can be conveniently moved to a suitable position. Then release the pressing plate 54. The restoring force of the return spring 52 and the retaining spring 62 drives the friction pad 43 to move forward quickly and squeeze against the inner wall of the chute 44. At the same time, due to the characteristics of the friction pad 43, it can effectively prevent the friction pad 43 from slipping off the chute 44 when the support partition 3 is in use. Thus, it is convenient to use the support partition 3.

[0027] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the fixation of the support partition 3, a retaining structure is arranged on the bottom side of the installation cavity 4. Specifically, it includes a positioning block 6. The positioning block 6 is installed on the inner wall of the bottom side of the installation cavity 4. A guide rod 61 is slidably installed on the positioning block 6. The other end of the guide rod 61 is installed on the transmission rod 41. A retaining spring 62 is sleeved on the guide rod 61. One end of the retaining spring 62 is installed on the positioning block 6. The other end of the retaining spring 62 is installed on the guide rod 61. When the transmission rod 41 moves backward, the retaining spring 62 is compressed. When the support partition 3 needs to be fixed, the restoring force of the retaining spring 62 can effectively increase the extrusion of the friction pad 43 against the chute 44. The other features are the same as those in Embodiment 1.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
