Description

Technical Field

[0001] The utility model belongs to the technical field of solid wood board manufacturing, and particularly relates to a three-layer solid wood structure with anti-deformation function. Background Art

[0002] The three-layer solid wood board is a solid wood material formed by splicing three layers of boards, namely the surface board, the core board, and the back board. It has the advantages of high stability, anti-deformation property, and cost saving. The surface layer is mostly made of high-quality hardwood, which is beautiful and durable; the core board and the back board are usually made of cheaper pinewood and other materials to reduce costs. The three-layer structure intersects with each other, effectively reducing the shrinkage and distortion of the wood and extending the service life. At the same time, the three-layer solid wood board is also widely used in furniture making, such as solid wood beds, tables, cabinets, etc., adding a natural and warm atmosphere to the home.

[0003] In the common design of the three-layer solid wood structure, a structure form is usually adopted in which two groups of surface boards are interposed with a core layer board between the balance layer boards. However, when the wood is subjected to external forces in this traditional structure, it is easy to deform, reducing the structural stability and durability of the product. In addition, due to the expansion and contraction characteristics of the wood itself, the traditional connection methods often have difficulty coping with these changes, resulting in problems such as loose structure, cracking, and deformation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-layer solid wood structure with anti-deformation function in order to solve the problems of easy deformation, looseness, cracking, etc. of common solid wood boards.

[0005] The utility model realizes the above purpose through the following technical solutions: It includes two groups of surface boards and balance layer boards, and a core layer board is interposed between the two balance layer boards. The core layer board includes a long wood core with a bevel design on one side, and the bevels of two adjacent long wood cores are mutually embedded. Semi-circular grooves are provided on both the bevel and vertical surfaces on both sides of the long wood core, and semi-circular snap grooves with a larger diameter are provided at both ends of the semi-circular grooves.

[0006] Furthermore, a round rod is inserted into the semi-circular groove and bonded with glue. The round rod is made of wood with higher toughness.

[0007] Furthermore, ring buckles are sleeved at both ends of the round rod. The ring buckles are made of wood with high hardness. The ring buckles are embedded inside the semi-circular snap grooves and bonded with glue. The inner diameter of the inner ring of the ring buckle is the same as the diameter of the round rod, and a bevel is provided at one end of the inner ring of the ring buckle.

[0008] Furthermore, the outer surfaces of the long wood cores are all in a rough state, and the outer surfaces of the round rod and the ring buckles are all in a smooth state after being polished.

[0009] Furthermore, the surface board, the balance layer board and the core layer board are adhesively bonded with glue and then pressed under high pressure.

[0010] Beneficial effects: The design of the present utility model is reasonable and has the following beneficial effects:

[0011] 1. In the solution of the present utility model, the core layer board is interposed between two groups of surface boards and the balance layer board. In particular, the long wood cores with inclined surfaces in the core layer board, and the inclined surfaces of adjacent long wood cores are mutually engaged, significantly enhancing the strength of the overall structure. This design effectively prevents the deformation of the wood under external forces, improving the structural stability and durability of the product;

[0012] 2. In the solution of the present utility model, semi-circular grooves are provided on the inclined surfaces and vertical surfaces of the long wood cores, and round rods with high toughness are inserted into the semi-circular grooves, significantly strengthening the connection between the long wood cores. This not only improves the structural stability of the overall core layer board but also enhances the durability, effectively coping with the expansion and contraction of the wood, reducing the risk of cracking and deformation. The ring buckles sleeved at both ends of the round rod provide additional fixing points for the round rod 7, not only enhancing the stability and strength of the connection but also enabling external forces to be directly transmitted to the round rod, further reducing the risk of cracking and deformation of the long wood cores.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments.

[0019] Combined with Figures 1 to 4A three-layer solid wood structure for preventing deformation is shown, including two groups of surface boards 1 and a balance layer board 2. A core layer board 3 is clamped between the two balance layer boards 2. The core layer board 3 includes a long wood core 4 with a bevel design on one side. The bevels of two adjacent long wood cores 4 are mutually engaged. Semi-circular grooves 5 are provided on both the bevel and vertical surfaces of the long wood core 4. Larger semi-circular snap grooves 6 are provided at both ends of the semi-circular grooves 5. The bevel design of adjacent long wood cores 4 enhances the structural strength of the core layer board 3 and effectively prevents deformation caused by external forces on the wood.

[0020] Among them, a round rod 7 is inserted into the semi-circular groove 5 and bonded with glue. The round rod 7 is made of wood with higher toughness. The insertion of the round rod 7 significantly strengthens the connection between the long wood cores 4, improves the stability and durability of the overall structure of the core layer board 3. The round wood rod 7 with higher toughness can better cope with the expansion and contraction of the wood, and can absorb external forces in a small amount. At the same time, it also has good support, reducing the risk of cracking and deformation.

[0021] Ring buckles 8 are sleeved at both ends of the round rod 7. The ring buckles 8 are made of wood with high hardness. The ring buckles 8 are embedded in the inner side of the semi-circular snap grooves 6 and bonded with glue. The inner diameter of the inner ring of the ring buckle 8 is the same as the diameter of the round rod 7. A bevel 9 is provided at one end of the inner ring of the ring buckle 8. The addition of the ring buckle 8 provides an additional fixed point for the round rod 7, further enhancing the stability and strength of the connection. The design of the bevel 9 facilitates the installation of the ring buckle 8. After installing the ring buckle 8, the outer surface is sealed with glue paint to further fix the ring buckle 8 and the round rod 7. At the same time, the ring buckle 8 can directly conduct external forces to the round rod 7, avoiding cracking and deformation of the long wood core 4.

[0022] The outer surfaces of the long wood cores 4 are all in a rough state, and the outer surfaces of the round rod 7 and the ring buckles 8 are all in a smooth state after polishing. The rough surface of the long wood core 4 increases the adhesion of the glue bonding, while the smooth surfaces of the round rod 7 and the ring buckles 8 reduce friction, facilitating installation and not being easily damaged.

[0023] The surface board 1, the balance layer board 2 and the core layer board 3 are all bonded with glue and then press-fitted under high pressure. The high-pressure press-fitting process ensures the tight fit between the layer boards, eliminates air and gaps, and improves the integrity and sealing of the structure.

[0024] Working principle: When the present utility model is in use, after aligning the long wood cores 4, the round rod 7 is inserted into the semi-circular groove 5, then the ring buckles 8 are sleeved at both ends of the round rod 7 and snapped into the semi-circular snap grooves 6. After applying glue, it is sent into the equipment for high-pressure press-fitting, and then the outer surface is sealed with glue paint to further fix the ring buckle 8 and the round rod 7;

[0025] When the wooden board is subjected to an external force, the surface layer board 1 and the balance layer board 2 conduct the external force to the core layer board 3. The inclined surface design of the adjacent long wooden cores 4 enhances the structural strength of the core layer board 3, effectively preventing deformation caused by the external force on the wood. At the same time, the loop buckle 8 can directly conduct the external force to the round rod 7, avoiding cracking and deformation of the long wooden cores 4.
