[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a composite curved board, comprising a curved board 1, a first connecting plate 2 installed on the upper part of the curved board 1, a second connecting plate 3 installed on the lower part of the curved board 1, a plurality of first grooves 4 installed at the curved portion of the upper part of the curved board 1, a first spring 5 installed inside the first groove 4, and a reinforcing plate 8 installed at the other end of the first spring 5. The reinforcing plate 8 is located between the curved board 1 and the first connecting plate 2, and a cavity 9 is provided between the curved board 1 and the reinforcing plate 8. When pressure is applied to the first connecting plate 2, the reinforcing plate 8 compresses the first spring 5, and the first spring 5 provides a reaction force to buffer the pressure on the reinforcing plate 8, thereby improving efficiency. The strength of the curved wooden board 1 at the bend is enhanced by the first groove 4 and cavity 9, which provide space for the compression and recovery of the first spring 5, ensuring its normal operation. A fixed sleeve 6 is installed at the inner bottom of the first spring 5, and a movable column 7 is installed at the upper part of the fixed sleeve 6. The top of the movable column 7 is fixedly connected to the top of the first spring 5. Through the combined action of the fixed sleeve 6 and the movable column 7, the first spring 5 can always move vertically, which facilitates better cushioning at the bend of the curved wooden board 1. An adhesive layer 11 is installed at the bottom of the second connecting plate 3. The adhesive layer 11 can significantly improve the physical and mechanical properties of the curved wooden board 1 and the second connecting plate 3, extending their service life. A moisture-proof layer 10 is installed between the second connecting plate 3 and the adhesive layer 11. This moisture-proof layer 10 prevents the bentwood board 1 and the second connecting plate 3 from getting damp, thus extending the service life of the bentwood board 1. An adhesive layer 13 is installed on the upper part of the first connecting plate 2. The adhesive layer 13 enhances the structural strength of the wood by bonding it to the surface. An impact-resistant layer 12 is installed between the first connecting plate 2 and the adhesive layer 13. This impact-resistant layer 12 strengthens the impact resistance of the bentwood board 1 and the first connecting plate 2 during use. A wear-resistant layer 14 is installed on top of the adhesive layer 13. This wear-resistant layer 14 improves the wear resistance, burn resistance, corrosion resistance, and moisture resistance of the bentwood board 1 and the first connecting plate 2. To extend the service life of the first connecting plate 2, an extension plate 15 is installed on one side of the first connecting plate 2, and a second groove 16 is installed inside the other side of the first connecting plate 2. Mounting holes 17 are installed at both ends of the second groove 16. The top of the mounting holes 17 passes through the second groove 16, the first connecting plate 2, and the wear-resistant layer 14, and the bottom of the mounting holes 17 passes through the second groove 16 and the second connecting plate 3 is located inside the curved board 1. Mounting holes 17 are installed at both ends of the extension plate 15. The extension plate 15 is placed inside the second groove 16 of another curved board 1, and the extension plate 15 can be fixed inside the second groove 16 through the mounting holes 17, so that the two curved board 1s can be fixedly connected.

[0023] Please see Figure 1 The rounded corners of the curved board 1 can effectively reduce the sharpness of the edges and corners, reduce the risk of collision, and increase the overall aesthetics and practicality of the curved board 1.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The mounting hole 17 has a threaded wire inside, and a bolt 18 is installed inside the mounting hole 17. The bolt 18 is threadedly engaged with the mounting hole 17. The extension plate 15 can be fixedly connected to the second groove 16 on another curved board 1 through the bolt 18, realizing the fixed connection of multiple combined curved boards. It can also be disassembled at any time according to specific conditions, improving the practicality and applicability of connecting multiple combined curved boards. A second spring 19 is installed on the outer wall of the bolt 18. The second spring 19 can absorb vibration and impact force, thereby extending the service life of the bolt 18. The second spring 19 can increase the friction between the bolt 18 and the mounting hole 17 through continuous elasticity, preventing the bolt 18 from loosening and making the connection of multiple combined curved boards more stable.
