[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a high-strength corrugated board, comprising a panel 1, a sliding groove 11 formed on the inner wall of the panel 1, the sliding groove 11 being trapezoidal in shape, a hollow block 13 slidably connected to the lower surface of the panel 1, and sliding blocks 12 fixedly connected to the upper and lower sides of the hollow block 13, the sliding blocks 12 being trapezoidal in shape and matching the shape of the sliding groove 11, the outer wall of the sliding block 12 being slidably connected to the inner wall of the sliding groove 11, a rectangular through hole provided inside the hollow block 13 for ventilation, the hollow block 13 for supporting the upper and lower sides of the panel 1, and multiple sets of hollow blocks 13 arranged laterally, and a reinforcing component 2 provided on the upper surface of the panel 1;

[0029] Specifically, a sliding block 12 slides in the sliding groove 11 inside the panel 1. The sliding block 12 is fixed on the upper and lower surfaces of the hollow block 13, which can achieve the effect of stably connecting the hollow block 13 and the panel 1. This structure can not only enhance the fracture resistance of the tube board, but also achieve the effect of heat preservation.

[0030] Reference Figure 2 and Figure 3 The reinforcing component 2 includes a reinforcing rib 21, the lower surface of which is slidably connected to the upper surface of the panel 1. The inner wall of the reinforcing rib 21 is provided with a positioning groove 22, which is trapezoidal in shape. A positioning block 23 is fixedly connected to the upper surface of the panel 1. The positioning block 23 is trapezoidal in shape and its shape matches the shape of the positioning groove 22. The outer wall of the positioning block 23 is fixedly connected to the right outer wall of the hollow block 13. The lower surface of the positioning block 23 is fixedly connected to the upper surface of the panel 1. The outer wall of the positioning block 23 is slidably connected to the inner wall of the positioning groove 22. A fixed outer frame 3 is provided on the outer side of the reinforcing rib 21.

[0031] Specifically, the outer walls of the hollow block 13 and the positioning block 23 on the panel 1 are slidably reinforced with ribs 21, which enable the panel 1 and the hollow block 13 to be connected, thereby achieving the effect of strengthening the strength of the corrugated board.

[0032] Reference Figure 3 and Figure 4The fixed outer frame 3 includes a second outer frame 32. The outer wall of the second outer frame 32 is disposed on the outside of the reinforcing component 2. The outer wall of the second outer frame 32 is slidably connected to the inside of the panel 1. A rectangular through hole is opened on the inner wall of the second outer frame 32. The rectangular through hole of the second outer frame 32 is connected to the rectangular through hole of the hollow block 13. A first outer frame 31 is slidably connected to the outer wall of the second outer frame 32. The outer wall of the first outer frame 31 is slidably connected to the inside of the panel 1. A hollow groove 33 is opened on the inner wall of the second outer frame 32. A limiting block 34 is fixedly connected to the upper surface of the second outer frame 32. The limiting block 34 is trapezoidal in shape. The outer wall of the limiting block 34 is slidably connected to the inner wall of the sliding groove 11. A connecting component 4 is provided on the left outer wall of the second outer frame 32.

[0033] Specifically, the limiting block 34 on the second outer frame 32 is slid into the sliding groove 11 on the panel 1, so that the second outer frame 32 and the panel 1 can be stably connected. The second outer frame 32 is connected to the first outer frame 31, which is connected in the middle of the upper and lower panels 1, forming a frame with the second outer frame 32. The hollow groove 33 opened on the second outer frame 32 can be ventilated. This structure can distribute the stress on the corrugated board to the frame, thereby strengthening the strength of the corrugated board.

[0034] Reference Figure 1 and Figure 5 The connecting component 4 includes a first outer shell 41, a second outer frame 32 fixedly connected to the right outer wall of the first outer shell 41, a rotating rod 42 rotatably connected to the inner wall of the first outer shell 41, the right outer wall of the rotating rod 42 rotatably connected to the left outer wall of the second outer frame 32, a spring 43 fixedly connected to the outer wall of the rotating rod 42, and the outer wall of the spring 43 slidably connected to the inner wall of the first outer shell 41; a handle 44 fixedly connected to the outer wall of the spring 43, a connecting block 45 fixedly connected to the outer wall of the handle 44, the outer wall of the connecting block 45 slidably connected to the left outer wall of the first outer shell 41, and the right outer wall of the connecting block 45 slidably connected to the outer wall of the second outer frame 32; a locking block 46 slidably connected to the inner wall of the first outer shell 41, a second outer shell 47 fixedly connected to the outer wall of the locking block 46, and the inner wall of the second outer shell 47 slidably connected to the outer wall of the connecting block 45;

[0035] Specifically, the first outer shell 41 and the second outer shell 47 are brought together so that the locking blocks 46 fixed on the two can slide into the corresponding grooves, allowing them to connect accurately. When connected, the handle 44 and the connecting block 45 are rotated, and then the two return to their original positions under the action of the rotating rod 42 and the spring 43, so that the first outer shell 41 and the second outer shell 47 are self-locked. This structure not only achieves the effect of quickly assembling and disassembling the first outer frame 31 and the second outer frame 32, but also achieves the effect of self-locking.

[0036] Working principle: When the corrugated board is needed, the sliding blocks 12 fixed on the upper and lower surfaces of the hollow block 13 are slid into the sliding grooves 11 opened in the panel 1, connecting the upper and lower panels 1 with the hollow block 13, thus separating the two panels 1. This strengthens the fracture resistance of the corrugated board while also providing effective heat insulation. Positioning blocks 23 are provided on the right outer wall of the hollow block 13 and the upper surface of the panel 1. Aligning the positioning grooves 22 in the reinforcing ribs 21 with the positioning blocks 23 and sliding them on their outer walls further strengthens the fracture resistance of the corrugated board. The outer wall of the first outer frame 31 is slid into the left and right gaps formed by the upper and lower panels 1, and the limiting blocks 34 on the second outer frame 32 are slid into the sliding grooves 11 on the panel 1, achieving a stable connection between the second outer frame 32 and the upper and lower panels 1. The frame formed by the first outer frame 31 and the second outer frame 32 disperses the stress on the surface of the corrugated board to the outer frame, reducing the stress on the panel 1. The first outer shell 41 and the second outer shell 47, fixed to the outer walls of the first outer frame 31 and the second outer frame 32, are brought together. The locking blocks 46 on both shells slide into the grooves to achieve a stable connection. When brought together, the connecting block 45 and the handle 44 can rotate, allowing the two connecting blocks 45 to connect. Under the action of the spring 43, the handle 44 and the connecting block 45 return to their original positions, thus achieving a self-locking and stable connection between the first outer shell 41 and the second outer shell 47. When separation is required, the handle 44 is moved to rotate the connecting block 45, causing the first outer shell 41 and the second outer shell 47 to separate. This structure is used to connect the first outer frame 31 and the second outer frame 32, enabling a stable connection and quick assembly and disassembly. These structures not only solve the problem that the stress on the surface of the existing corrugated board is entirely borne by the surface of the board when subjected to external impact, and the stress cannot be dispersed, which leads to the corrugated board breaking when subjected to small impacts, but also solve the problem of cumbersome operation when replacing the outer frame.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
