Description

Technical Field

[0001] This utility model relates to the field of board technology, specifically to a multi-layered, resilient solid wood board. Background Technology

[0002] Multi-layer resilient solid wood boards refer to wood-based panels made of two or more layers of veneer, stacked together with different wood grain directions using a specific process. These boards possess excellent resilience. Compared to ordinary solid wood boards, multi-layer resilient solid wood boards are characterized by their superior toughness. When subjected to external impacts, bending, or stress caused by environmental changes, they can better absorb and disperse energy, making them less prone to breakage, warping, or other damage. They also possess good compressive and tensile mechanical properties. This type of board is widely used in furniture manufacturing (such as wardrobes and cabinets), interior decoration (such as flooring and wall panels), and handicrafts.

[0003] A search revealed a Chinese utility model patent, CN211362670U, which discloses a multi-layered, resilient solid wood board. The solid wood board is composed of N layers of veneers stacked together with different wood grain directions, where N ≥ 2. At least one metal frame is embedded in the solid wood board, with the thickness of the metal frame matching the thickness of the solid wood board. This utility model solves the problems of poor deformation resistance and easy cracking of the surface veneers in solid wood boards, improving the surface flatness and overall structural stability of the solid wood board. This utility model is applicable to furniture making and home decoration lighting, and can be used in the production of wardrobes, cabinets, doors, and other cabinet doors.

[0004] However, the device lacks the ability to partially replace veneers. When the solid wood board is subjected to a large external impact or concentrated load, such as being hit by a heavy object or punctured by a sharp object, even if the overall board has a certain degree of toughness, a certain veneer may be subjected to excessive stress and break. Since the solid wood board is glued together, the broken veneer cannot be replaced locally, and the entire solid wood board can only be replaced, which increases costs and wastes resources. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layered, resilient solid wood board to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layered, resilient solid wood board includes a single veneer. The single veneer has several vertical grooves, annular grooves on the inner walls of the vertical grooves, several insertion grooves on the inner walls of the annular grooves, and several locking grooves on the inner walls of the annular grooves away from the insertion grooves. A second veneer is slidably connected to the bottom of the single veneer. The second veneer has several vertical grooves, and a rotating groove is formed in the interior of the second veneer near the vertical grooves. A rotating block is slidably connected to the inner wall of the rotating groove, and a spring is fixedly connected to the top of the rotating block. A limit component is slidably connected to the top of the spring.

[0008] Preferably, the limiting component includes a main rod, a plurality of locking strips are fixedly connected to the outer surface of the main rod, locking strips are slidably connected to the inner wall of the locking groove, and the main rod is slidably connected to the inner wall of the vertical groove.

[0009] Preferably, the single board one and the single board two are provided with a plurality of strip grooves at the distance from the vertical groove, and the inner wall of the strip groove is slidably connected with an elastic resin strip.

[0010] Preferably, the top of the first single board is fixedly connected with a wear-resistant coating one, and the bottom of the second single board is fixedly connected with a wear-resistant coating two.

[0011] Preferably, the central axes of the first plate and the second plate coincide.

[0012] Preferably, the four vertical grooves are evenly distributed at the edges of single plate one and single plate two.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This multi-layered, resilient solid wood board features vertical grooves, insertion grooves, annular grooves, locking grooves, and limiting components. During use, single veneers are stacked, the main rod on the limiting component is aligned with the vertical groove, and the locking strip is aligned with the insertion groove. The limiting component is inserted into the vertical groove until the bottom of the main rod touches and compresses the spring. Pressure is continued on the main rod until the bottom locking strip is flush with the annular groove on single veneer two. The main rod is rotated, causing the rotating block to rotate within the rotating groove, which in turn causes the locking strip to rotate within the annular groove until it reaches the locking groove. Pressure on the main rod is then stopped, and the locking strip engages with the locking groove under spring pressure, thus securing single veneer one and single veneer two. If one layer of the multi-layered board breaks due to external factors, the process can be reversed to separate single veneer one and single veneer two, replace the broken single veneer, and recycle the broken single veneer. This partial replacement achieves cost reduction and resource conservation.

[0015] This multi-layered, resilient solid wood board features grooves and elastic resin strips. During use, the grooves provide allowance for deformation of the veneer, while the embedded elastic resin strips increase the board's toughness and impact resistance, thus extending its service life.

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] The multi-layered, resilient solid wood board includes a veneer 1. Veneer 1 has several vertical grooves 2, with annular grooves 3 on the inner wall of each groove 2. The inner wall of each annular groove 3 has several insertion grooves 4, and the inner wall of each annular groove 3 away from the insertion grooves 4 has several locking grooves 5. A veneer 2 6 is slidably connected to the bottom of veneer 1. Veneer 2 6 has several vertical grooves 2, and a rotating groove 7 is formed inside veneer 2 near the vertical grooves 2. A rotating block 8 is slidably connected to the inner wall of the rotating groove 7, and a spring 9 is fixedly connected to the top of the rotating block 8. 9. The top sliding connection is limited by the component 10. In use, single board 1 is aligned with single board 2 6 and stacked. The main rod 11 on the limiting component 10 is aligned with the vertical groove 2 and the locking strip 12 is aligned with the groove 4. The limiting component 10 is inserted into the vertical groove 2 until the bottom of the main rod 11 touches the spring 9 and compresses the spring 9. Continue to press the main rod 11 until the bottom locking strip 12 is level with the annular groove 3 on single board 2 6. Rotate the main rod 11 to drive the rotating block 8 to rotate in the rotating groove 7, and drive the locking strip 12 in the annular groove 3. The main rod 11 rotates within slot 3 until the locking strip 12 rotates to slot 5, at which point the pressure on the main rod 11 stops. Under the action of spring 9, the locking strip 12 engages with slot 5, completing the fixation of single board 1 and single board 2 6. When one layer of the multi-layer structure board breaks due to external factors, the operation can be reversed to separate single board 1 and single board 2 6, replace with a new single board, and recycle the broken single board. It should be noted that the bottom of the main rod 11 has a large friction force, so when it resists the spring 9 and rotates, it is sufficient to drive the rotating block 8 to rotate within the rotating slot 7. Single board 1 is not a single board, but a collective term for boards of one or more stacked together. This device uses the limiting component 10 to fix the multi-layer single board 1 and single board 2 6, which is more secure than traditional screw fixing, allows for more disassembly and assembly, and does not require special tools, only a long strip with high friction. In addition, assembly and disassembly are simple and quick. This solid wood board structure does not use traditional glue bonding, which is more environmentally friendly and provides customers with a better user experience.

[0024] In this embodiment, preferably, the limiting component 10 includes a main rod 11, with a plurality of locking strips 12 fixedly connected to the outer surface of the main rod 11, the locking strips 12 slidably connected to the inner wall of the locking groove 5, and the main rod 11 slidably connected to the inner wall of the vertical groove 2. In use, single board 1 is aligned with single board 2 6 and stacked, the main rod 11 on the limiting component 10 is aligned with the vertical groove 2 and the locking strips 12 are aligned with the insertion groove 4, and the limiting component 10 is inserted into the vertical groove 2 until the bottom of the main rod 11 touches the spring 9 and compresses the spring. Using spring 9, continue pressing the main rod 11 until the bottom locking strip 12 is level with the annular groove 3 on the second single plate 6. Rotate the main rod 11, causing the rotating block 8 to rotate in the rotating groove 7, which in turn causes the locking strip 12 to rotate in the annular groove 3 until the locking strip 12 rotates to the locking groove 5. Stop applying pressure to the main rod 11. Under the action of spring 9, the locking strip 12 is engaged in the locking groove 5, completing the fixing of the first single plate 1 and the second single plate 6. The operation is simple and quick, saving time and effort, and reducing costs and improving productivity to a certain extent.

[0025] In this embodiment, preferably, a plurality of strip grooves 13 are provided on the single board 1 and the single board 2 away from the vertical groove 2. The inner wall of the strip groove 13 is slidably connected with an elastic resin strip 14. In use, the setting of the strip groove 13 provides deformation margin for the single board. At the same time, the elastic resin strip 14 is embedded in the strip groove 13 to increase the toughness of the solid wood board and enhance the impact resistance of the solid wood board, thereby achieving the effect of extending the service life of the solid wood board.

[0026] In this embodiment, preferably, the top of veneer 1 is fixedly connected with wear-resistant coating 15, and the bottom of veneer 6 is fixedly connected with wear-resistant coating 16. During use, the parts that have the most contact with the outside world are provided with wear-resistant coatings. The wear-resistant coatings here have the effect of epoxy resin, with strong adhesion, high hardness, and strong wear resistance, thus protecting the surface of the wood.

[0027] In this embodiment, preferably, the central axes of veneer 1 and veneer 2 6 are coincident. In use, veneer 1 is aligned with veneer 2 6 and stacked, the main rod 11 on the limiting component 10 is aligned with the vertical groove 2 and the locking strip 12 is aligned with the groove 4, and the limiting component 10 is inserted into the vertical groove 2. By overlapping the veneer layers and making the grain direction of adjacent layers perpendicular to each other, the mechanical properties of the wood in all directions can be more balanced, thus improving the structural stability of the solid wood board.

[0028] In this embodiment, preferably, the four vertical grooves 2 are evenly distributed at the edges of the first veneer 1 and the second veneer 6. When in use, the veneers are stacked one on top of the other, which is unstable and can be displaced in any direction. The vertical grooves 2 and the limiting components 10 are set at the corners of the veneers to ensure the stability between the veneers to a great extent and improve the overall quality of the solid wood board.

[0029] Working principle: In this embodiment, the multi-layered resilient solid wood board is used by overlapping single board 1 with single board 2 6, aligning the main rod 11 on the limiting component 10 with the vertical groove 2 and the locking strip 12 with the insertion groove 4, inserting the limiting component 10 into the vertical groove 2 until the bottom of the main rod 11 touches the spring 9 and compresses the spring 9, and continuing to press the main rod 11 until the bottom locking strip 12 is level with the annular groove 3 on single board 2 6, rotating the main rod 11, driving the rotating block 8 to rotate in the rotating groove 7, driving the locking strip 12 to rotate in the annular groove 3, until the locking strip 12 rotates to the locking groove 5, stopping the pressure on the main rod 11, and the locking strip 12 is locked into the locking groove 5 under the action of the spring 9, thus completing the fixation of single board 1 and single board 2 6. When one layer of the multi-layered board is broken due to external factors, the operation can be reversed to separate single board 1 and single board 2 6, replace with a new single board, and recycle the broken single board.
