[0002] Particleboard is a common type of engineered wood product, mainly made from wood chips or other wood fiber materials. During the manufacturing process, wood is cut into chips of a certain size, dried, glued, and then pressed into boards under heat and pressure. The surface of particleboard is usually rough, but it can be decorated with veneer, paint, and other processes to improve its appearance and durability. Due to its low cost, easy processing, and stable performance, this type of board is widely used in furniture manufacturing, interior decoration, and the construction industry.
[0003] However, existing particleboard has low structural strength, and it is prone to softening and damage after being bumped on all four sides. After installation, the core plywood is easily exposed, which in turn affects the overall service life of the particleboard. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides the following technical solution: a particleboard with high physical and mechanical properties, comprising an outer particleboard layer and two core boards disposed between the outer particleboard layer.
[0006] An intermediate clamping plate is provided between the two core boards. The intermediate clamping plate is provided with surrounding plates on its four sides.

[0008] Preferably, the two insert blocks and splicing frame are arranged alternately on the back of the core board. The two core boards can clamp the middle clamping plate in the middle and splice back to back. The middle clamping plate is respectively bonded and fixed to the core board, and the contact surfaces between the core boards are also bonded and fixed with glue.
[0009] Preferably, the clamping groove and the outer particleboard are integrally formed, the fixed clamping plate and the movable clamping plate can be respectively assembled with the clamping groove, the assembled component is integrally formed with the side assembled plate, the assembled groove is integrally formed with the surrounding plate, and the assembled component can be spliced with the assembled groove.
[0010] Preferably, the assembly component and the side assembly plate can be fixedly installed to the surrounding plate by fixing screws and screw holes, and the fixing clamp is welded to the side assembly plate.
[0011] Preferably, three sliding rods are provided on one side of the movable clamping plate.

A baffle is provided at the other end of the sliding rod and the baffle is welded to the sliding rod.
[0012] Preferably, the side splicing plate has three sliding cavities inside, and the baffle and sliding rod can slide inside the sliding cavities. A spring is provided on the outside of the sliding rod, and the spring is installed inside the sliding cavity. Pulling the movable clamping plate outward will compress the spring.
[0013] Compared with the prior art, this utility model provides a particleboard with high physical and mechanical properties, which has the following beneficial effects:
[0014] 1. By using a combination of intermediate clamping plates, inner inserts, splicing frames, splicing grooves, hollow frames, and surrounding panels, the structure achieves lightweighting while significantly improving structural stability and resistance to deformation. The metal intermediate clamping plates are welded to the surrounding panels to form a rigid skeleton. Combined with the weight-reducing design of the hollow frames, this ensures both support strength and reduces material consumption. The precise fit between the inner inserts and splicing grooves, as well as the staggered layout of the inner inserts and splicing frames, makes the back-to-back splicing of the intermediate clamping plates and core boards more stable. The adhesive bonding process significantly enhances the interlayer bonding force. This composite connection structure effectively disperses stress concentration and forms a multi-directional force network, enabling the board to withstand complex loads. It is particularly suitable for applications requiring high bending strength and impact resistance. The edge-wrapping design of the surrounding panels also prevents damage from bumps and knocks at the corners and avoids the outer particleboard from softening and falling off during use, thereby extending the overall service life of the board.
[0015] 2. Through the arrangement of clamping grooves, fixed clamping plates, movable clamping plates, assemblies, side assemblies, assemblies, fixing screws, screw holes, sliding rods, springs, baffles, and sliding cavities, a stable assembly of the perimeter panel and the side assemblies is achieved. The movable clamping plate, with the help of the elastic sliding mechanism of the sliding rod in the sliding cavity, automatically adjusts the clamping force through the compression and rebound of the spring, so that the movable clamping plate and the fixed clamping plate can adaptively clamp the outer particleboard. This dynamic clamping system, in conjunction with the clamping grooves, ensures a tight fit between the outer particleboard, the core board, and the intermediate clamping plate, maintaining the overall structural integrity of the board while ensuring its excellent physical and mechanical properties.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides, for example Figure 1-6The illustrated particleboard with high physical and mechanical properties includes an outer particleboard 2 and two core boards 6 disposed between the outer particleboard 2.
[0025] A middle clamping plate 7 is provided between two core boards 6. The middle clamping plate 7 is provided with a surrounding plate 1 on each of its four sides. The middle clamping plate 7 is provided with four hollow frames 14. Two inner inserts 15 are provided on the back of the core board 6. Two splicing frames 16 are also provided on the back of the core board 6. Splicing grooves 17 are provided in the middle of the splicing frames 16. Two pairs of splicing grooves 8 are provided on each side of the surrounding plate 1. A pair of screw holes 12 are provided on each splicing groove 8. Two side splicing plates 3 are provided on each side of the surrounding plate 1. Movable clamping plates 4 and fixed clamping plates 13 are provided on each side of the side splicing plates 3. Splicing parts 9 are provided above and below the side splicing plates 3. A pair of screw holes 12 are provided on each splicing part 9.
[0026] In this embodiment, the particleboard is a common type of engineered wood product, mainly made from wood or other wood fiber materials. During the manufacturing process, the wood is cut into pieces of a certain size, dried, and then glued together with adhesive. The particleboard is then pressed into a board under heat and pressure. The forming process of the particleboard is as follows: First, the outer particleboard 2 is hot-pressed and aligned with the core board 6 in the middle using convex ridges. Then, the outer particleboard 2 and the core board 6 are glued together. Next, the two core boards 6 on both sides are joined back to back and the middle clamping plate 7 is sandwiched in the middle. The two core boards 6 are then glued together again. Finally, the side splicing plates 3 are installed on both sides to fix the two sides of the particleboard.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the intermediate clamping plate 7 is made of metal material. The surrounding plate 1 is welded to the intermediate clamping plate 7. The inner insert block 15 is integrally formed with the core plate 6. The splicing frame 16 is integrally formed with the core plate 6. The splicing frame 16 can be inserted into the splicing frame 16 on the intermediate clamping plate 7. The inner insert block 15 can be spliced with the splicing groove 17 on the splicing frame 16. The two inner insert blocks 15 and the splicing frame 16 are arranged alternately on the back of the core plate 6. The two core plates 6 can clamp the intermediate clamping plate 7 in the middle and splice back to back. The intermediate clamping plate 7 is respectively bonded and fixed to the core plate 6. The contact surfaces between the core plates 6 are also bonded and fixed with glue.
[0028] Preferably, through the arrangement of the intermediate clamping plate 7, inner insert block 15, splicing frame 16, splicing groove 17, hollow frame 14, and surrounding plate 1, the particleboard significantly improves the overall structural stability and deformation resistance while maintaining its lightweight characteristics. The metal intermediate clamping plate 7 forms a rigid frame through welding the surrounding plate 1, and the weight-reducing design of the hollow frame 14 effectively reduces material consumption while ensuring support strength. The precise splicing of the inner insert block 15 and the splicing groove 17, and the staggered arrangement of the inner insert block 15 and the splicing frame 16, ensure that the intermediate clamping plate 7 and the two core boards 6 are back-to-back The back-to-back splicing is more stable, and the bonding force between the layers is greatly enhanced by the final adhesive method. This composite connection method not only disperses stress concentration, but also forms a multi-directional force network through the staggered inner inserts 15 and splicing frames 16, enabling the board to withstand complex loads. It is especially suitable for application scenarios with high requirements for planar bending strength and impact resistance. The surrounding panel 1 can protect the four sides of the particleboard to prevent the particleboard from being bumped and causing the outer particleboard 2 to become soft and damaged, and to avoid the middle plywood 7 being easily exposed after installation, thereby improving the overall service life of the particleboard.
[0029] like Figure 3 and Figure 6 As shown, the clamping groove 5 and the outer particleboard 2 are integrally formed. The fixed clamping plate 13 and the movable clamping plate 4 can be assembled with the clamping groove 5 respectively. The assembly part 9 and the side assembly plate 3 are integrally formed. The assembly groove 8 and the surrounding plate 1 are integrally formed. The assembly part 9 can be assembled with the assembly groove 8. The assembly part 9 and the side assembly plate 3 can be fixedly installed with the surrounding plate 1 through the fixing screws 11 and screw holes 12. The fixed clamping plate 13 is welded to the side assembly plate 3. Three sliding rods 20 are provided on one side of the movable clamping plate 4. The sliding rods 20 are welded to the movable clamping plate 4. The sliding rods 20 are respectively inserted into the side assembly plate 3. A baffle 19 is provided at the other end of the sliding rod 20. The baffle 19 is welded to the sliding rod 20. Three sliding cavities 18 are provided inside the side assembly plate 3. The baffle 19 and the sliding rods 20 can slide inside the sliding cavities 18. A spring 10 is provided on the outside of the sliding rod 20. The spring 10 is installed inside the sliding cavity 18. Pulling the movable clamping plate 4 outward will compress the spring 10.
[0030] Preferably, through the arrangement of the clamping groove 5, the fixed clamping plate 13, the movable clamping plate 4, the splicing component 9, the side splicing plate 3, the splicing groove 8, the fixing screw 11, the screw hole 12, the sliding rod 20, the spring 10, the baffle 19, and the sliding cavity 18, the splicing component 9 can be spliced with the splicing groove 8, and the side splicing plate 3 and the surrounding plate 1 are rigidly connected through the fixing screw 11 and the screw hole 12. The movable clamping plate 4 can slide in the sliding cavity 18 through the sliding rod 20. When the sliding rod 20 slides outward, the baffle 19 will continuously compress the spring 10. When the movable clamping plate 4 is spliced with the clamping groove 5, the rebound of the spring 10 will make the movable clamping plate 4 tightly clamp the outer particleboard 2. Through the cooperation of the fixed clamping plate 13 and the movable clamping plate 4 with the clamping groove 5, the outer particleboard 2, the core plate 6 and the middle clamping plate 7 can be tightly fitted together, ensuring the integrity of the particleboard and maintaining the high physical and mechanical properties of the particleboard.
