Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture panel technology, and in particular to a mortise and tenon structure panel that is resistant to deformation. Background Technology
[0002] In the application of wood furniture products (such as door panels and wood veneers), the deformation of the boards has long plagued the industry. Current technologies mostly employ simple splicing or traditional mortise and tenon joints, which, due to the physical properties of wood's thermal expansion and contraction, exhibit significant drawbacks in practical applications. While traditional mortise and tenon joints can achieve a preliminary connection, most are not optimized for the physical deformation characteristics of wood and lack sufficient elasticity. When the ambient temperature and humidity change, the thermal expansion and contraction of the wood in the length, width, and thickness directions will disrupt the stress balance between the mortise and tenon joints: either expansion will cause excessive compression between the tenon and mortise, leading to local deformation of the board or even damage to the mortise and tenon structure; or contraction will cause the mortise and tenon connection to loosen, creating gaps, which will then cause the boards to wobble due to external forces or their own weight during use, seriously affecting the overall stability and service life of the board. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a mortise and tenon structure board that is resistant to deformation. It solves the technical problems of existing mortise and tenon connections not adapting to the thermal expansion and contraction characteristics of wood, lacking elastic expansion space, easily causing mortise and tenon damage due to compression during expansion, and easily causing loosening and shaking during contraction, which seriously affects the stability and service life of the board. It achieves the purpose of adapting to the thermal expansion and contraction characteristics of wood, reserving elastic expansion space, avoiding mortise and tenon damage or loosening and shaking, and enhancing the stability, sealing and structural integrity of the board connection.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mortise and tenon structure plate for preventing deformation, including a plate body, a T-shaped groove is provided on one side of the plate body, and a T-shaped slider is fixedly connected to the other side of the plate body and slides in the T-shaped groove. A spring hole is provided in the inner wall of the T-shaped groove, a compression spring is fixedly connected in the spring hole, and an insertion rod is fixedly connected to the end of the compression spring and slides in the spring hole. A fixing hole is provided on the T-shaped slider, and the insertion rod is inserted into the fixing hole to complete the connection and fixation of the plate.
[0005] A further improvement is that the cross-sectional area of the T-shaped groove is larger than the area of the T-shaped slider, and the T-shaped groove is filled with an elastic sealing strip.
[0006] A further improvement is that the width of the board body is 20mm-30mm, and a 2mm gap is reserved laterally at the tenon joint of two connected board bodies. Elastic sealing strips are also installed on both sides of the board body.
[0007] A further improvement is that the spring hole, the plug rod slidably disposed inside it, and the fixing hole are all square structures. The cross-sectional area of the outer end of the inner wall of the spring hole is larger than the cross-sectional area of the rear end, and the cross-sectional area of the fixing hole is the same as the cross-sectional area of the outer end of the spring hole. Elastic metal sheets are fixed to all four sides of the outer end of the plug rod, and the elastic metal sheets are interference fit with the fixing holes.
[0008] A further improvement is that a compression spring is fixedly connected between the elastic metal sheet and the plug rod.
[0009] A further improvement is that moisture-proof decorative panels are installed on the front and back sides of the board body, which are made of 2mm-3mm horizontal wood grain material, and the outer sides of the two moisture-proof decorative panels are coated with a waterproof paint layer.
[0010] By employing the above technical solution, this utility model provides a mortise and tenon structure plate that is resistant to deformation, which has at least the following beneficial effects: 1. This utility model can quickly complete the mortise and tenon connection of two board bodies by inserting the T-shaped slider on the right side of one board body into the T-shaped groove on the left side of the original board body. During the insertion process, the T-shaped slider squeezes the insertion rod, causing it to retract into the spring hole and compress the compression spring. When the fixing hole on the T-shaped slider coincides with the position of the insertion rod, the compression spring returns to its original position under its own elasticity, thereby pushing the insertion rod into the fixing hole, completing the fixation of the two board bodies and preventing them from separating.
[0011] 2. This utility model fills the T-shaped groove with an elastic sealing strip. When the T-shaped slider expands due to heat, it squeezes the elastic sealing strip. By utilizing the compressible property of the elastic sealing strip, stress expansion space is provided, which also enhances the overall structure. When the T-shaped slider shrinks due to cold, the elastic sealing strip releases its own elasticity to fill the shrinkage space, thereby preventing the tenon joint from being damaged or loosened by expansion and compression, and improving the stability of the connection of the plate body 1.
[0012] 3. This utility model minimizes the torsional stress coefficient of wood by setting the width of the board body between 20mm and 30mm. In addition, a 2mm gap is reserved at the connection between the two boards to allow space for the board body to expand when heated. In order to prevent the board body from shrinking when cooled, a 2mm-3mm moisture-proof decorative panel with horizontal wood grain material is installed on the front and back of the board body to make the tension of the front and back of the board body consistent, thereby achieving the purpose of preventing the board body from deforming.
[0013] 4. This utility model uses an interference fit between the elastic metal sheet and the fixing hole. Therefore, when the fixing hole expands due to heat, it compresses the elastic metal sheet, causing it to contract. When the fixing hole contracts due to cold, the elastic metal sheet releases its elasticity and remains tightly attached to the fixing hole, thereby improving the stability of the connection between the plug rod and the fixing hole and preventing loosening or shaking at the connection.

[0017] 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.
[0018] Example 1 Addressing the problem that existing mortise and tenon joints do not adapt to the thermal expansion and contraction characteristics of wood, lacking elastic expansion space, expansion easily leads to damage to the mortise and tenon joints due to compression, and contraction easily causes the connection to loosen and wobble, seriously affecting the stability and service life of the board, this embodiment provides a deformation-resistant mortise and tenon structure board that adapts to the thermal expansion and contraction characteristics of wood, reserves elastic expansion and contraction space, avoids damage to the mortise and tenon joints due to compression or loosening and wobble, and enhances the stability, sealing and structural integrity of the board connection. Please refer to... Figures 1-5The anti-deformation mortise and tenon structure panel includes a panel body 1. A T-shaped groove 2 is formed on one side of the panel body 1, and a T-shaped slider 3 is fixedly connected to the other side of the panel body 1, sliding within the T-shaped groove 2. A spring hole 4 is formed on the inner wall of the T-shaped groove 2, and a compression spring 5 is fixedly connected to the spring hole 4. A connecting rod 6, sliding within the spring hole 4, is fixedly connected to the end of the compression spring 5. A fixing hole 7 is formed on the T-shaped slider 3, and the connecting rod 6 is inserted into the fixing hole 7 to complete the connection and fixation of the panels. When splicing two panel bodies 1, one... The T-shaped slider 3 on the right side of the board body 1 is inserted into the T-shaped groove 2 on the left side of the initial board body 1, which can quickly complete the tenon and mortise connection of the two board bodies 1. During the insertion process, the T-shaped slider 3 presses the insertion rod 6, causing it to retract into the spring hole 4 and compress the compression spring 5. When the fixing hole 7 on the T-shaped slider 3 coincides with the position of the insertion rod 6, the compression spring 5 returns to its original position under its own elasticity, thereby pushing the insertion rod 6 into the fixing hole 7, completing the fixation of the two board bodies 1 and preventing them from separating.
[0019] To prevent the mortise and tenon joint from being damaged or loosened due to thermal expansion and contraction of the board body 1, the cross-sectional area of the T-shaped groove 2 is larger than that of the T-shaped slider 3, and the T-shaped groove 2 is filled with an elastic sealing strip 21. By filling the T-shaped groove 2 with the elastic sealing strip 21, when the T-shaped slider 3 expands due to heat, it compresses the elastic sealing strip 21. Utilizing the compressible property of the elastic sealing strip 21, stress expansion and contraction space is provided, which also enhances the overall structural integrity. When the T-shaped slider 3 shrinks due to cooling, the elastic sealing strip 21 releases its own elasticity to fill the shrinkage space, thereby preventing the mortise and tenon joint from being damaged or loosened due to expansion and compression, and improving the stability of the connection of the board body 1.
[0020] To prevent the two boards 1 from being too tightly connected and damaged by mutual compression due to thermal expansion and contraction, the width of the board 1 is 20mm-30mm. A 2mm gap is reserved laterally at the tenon joint of the two connected boards 1. Elastic sealing strips 21 are also installed on both sides of the board 1. By setting the width of the board 1 to between 20mm and 30mm, the torsional stress coefficient of the wood is minimized. The 2mm gap at the joint of the two boards 1 allows space for thermal expansion. In order to prevent the board 1 from shrinking when cooled, elastic sealing strips 21 are also provided on the sides of the board 1 to supplement the space for wood shrinkage and prevent dust or water from entering due to excessive gaps at the joint.
[0021] Furthermore, moisture-proof decorative panels 8 are installed on the front and back sides of the board body 1, which are made of 2mm-3mm horizontal wood grain material. The outer surfaces of the two moisture-proof decorative panels 8 are coated with a waterproof paint layer 9. The moisture-proof decorative panels 8 are made of 2mm-3mm horizontal wood grain material, so that the tension of the front and back sides of the board body 1 is consistent, thereby preventing the board body 1 from deforming. In addition, the waterproof paint layer 9 coated on the outer side of the moisture-proof decorative panels 8 further improves its waterproof effect.
[0022] Example 2 To prevent the fixing holes 7 on the T-shaped slider 3 from being squeezed and contracted when subjected to thermal expansion, or from expanding when cooled, thus causing loosening at the connection, therefore, based on Embodiment 1, as follows... Figures 1-5 As shown, the spring hole 4, the plug rod 6 slidably disposed inside it, and the fixing hole 7 are all square structures. The cross-sectional area of the outer end of the inner wall of the spring hole 4 is larger than that of the rear end, and the cross-sectional area of the fixing hole 7 is the same as that of the outer end of the spring hole 4. Elastic metal sheets 61 are fixedly attached to all four sides of the outer end of the plug rod 6, and the elastic metal sheets 61 and the fixing hole 7 are interference fit. When the plug rod 6 is inserted into the fixing hole 7, the elastic metal sheets 61 on its four sides are also inserted into the fixing hole 7 at the same time. Since the elastic metal sheets 61 and the fixing hole 7 are interference fit, when the fixing hole 7 expands due to heat, it squeezes the elastic metal sheets 61 and causes them to contract. When the fixing hole 7 contracts due to cold, the elastic metal sheets 61 release their elasticity and remain tightly attached to the fixing hole 7, thereby improving the stability of the connection between the plug rod 6 and the fixing hole 7 and preventing loosening and shaking at the connection.
[0023] To prevent the elastic metal sheet 61 from being compressed and deformed over a long period of time, which would result in a poor rebound effect, a compression spring sheet 62 is fixedly connected between the elastic metal sheet 61 and the plug rod 6. When the elastic metal sheet 61 is compressed, the compression spring sheet 62 is squeezed simultaneously. The compression spring sheet 62 assists the elastic metal sheet 61 in rebounding, thereby preventing the elastic metal sheet 61 from being deformed due to long-term compression, which would result in a poor rebound effect and cause the connection to loosen and wobble.
