[0002] Finger-jointed boards are made by splicing multiple pieces of wood together, without any additional plywood on top or bottom. Because the vertical boards are joined with a serrated joint, similar to interlacing fingers, the strength and appearance of the wood are enhanced, hence the name "finger-jointed board." It is used as a high-quality material for furniture, cabinets, wardrobes, etc. There are many types of finger-jointed boards, one of which is pine finger-jointed board. In the use of pine finger-jointed board, multiple pieces also need to be spliced ​​together.

[0003] In the prior art, a pine finger-jointed board has an embedding block on one side and an embedding groove on the other side. When splicing, the embedding block is embedded into the embedding groove, thereby completing the splicing of the pine finger-jointed board.

[0004] However, when the aforementioned pine finger-jointed boards are subjected to reverse tension during use, the tension acts between the serrated teeth and the slots, making them prone to delamination and breakage.

[0005] Therefore, this utility model proposes a new solution. Utility Model Content

[0028] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0029] like Figures 1-6 As shown, the firmly spliced ​​pine finger-jointed board provided in this embodiment includes a finger-jointed board body 1. A first step groove 2 is provided at the bottom of one end of the finger-jointed board body 1. A first step block 3 is connected to one end of the finger-jointed board body 1. A second step groove 4 that mates with the first step block 3 is provided at the top of the other end of the finger-jointed board body 1. A second step block 5 that mates with the first step groove 2 is connected to the other end of the finger-jointed board body 1. A first insertion tooth 6 is provided on the side of the first step block 3 away from the finger-jointed board body 1. A first slot 7 is provided at the end of the finger-jointed board body 1 located inside the first step groove 2. A second insertion tooth 8 that mates with the first slot 7 is provided on the side of the second step block 5 away from the finger-jointed board body 1. A second slot 9 that mates with the first insertion tooth 6 is provided at the end of the finger-jointed board body 1 located inside the second step groove 4. With the arrangement of the first insert 6, the first slot 7, the second insert 8, and the second slot 9, the total height of the inserts and slots at the same end of the finger joint plate body 1 is greater than the thickness of the finger joint plate body 1 due to the step design. This results in a longer splicing length compared to traditional splicing methods, thereby improving the splicing strength. Furthermore, with the arrangement of the first step groove 2, the first step block 3, the second step groove 4, and the second step block 5, the two finger joint plate bodies 1 can hook onto each other after splicing. Therefore, when subjected to tension, the force is prevented from acting directly on the inserts and slots, thus improving the splicing strength and preventing delamination and cracking.

[0030] In an optional embodiment, two connecting rods 10 are fixedly connected to the front outer wall of the finger joint plate body 1, and two connecting holes 11 that mate with the connecting rods 10 are provided on the back outer wall of the finger joint plate body 1. The connecting rods 10 and connecting holes 11 facilitate vertical splicing. It should be noted that the distance between the two connecting rods 10 is equal to half the difference between the length of the finger joint plate body 1 and the overlapping length between two adjacent spliced ​​finger joint plate bodies 1. Therefore, connecting rods 10 that satisfy this distance can be staggered when splicing adjacent rows of finger joint plate bodies 1, thereby improving the splicing strength.

[0031] In an optional embodiment, the top of the connecting rod 10 has a first mounting hole 12, and the top of the connecting hole 11 has a second mounting hole 13. A mounting rod 14 is connected between the first mounting hole 12 and the second mounting hole 13. The height of the mounting rod 14 is not less than the thickness of the finger joint plate body 1. The mounting rod 14 is in an interference fit with the first mounting hole 12 and the second mounting hole 13. One end of the connecting rod 10 is chamfered. By setting the first mounting hole 12, the second mounting hole 13 and the mounting rod 14, the splicing firmness can be improved when vertically splicing. The mounting rod 14 is a straight rod of the same material as the finger joint plate body 1. The mounting rod 14 is in an interference fit with the first mounting hole 12 and the second mounting hole 13. A wooden hammer is used for installation to improve the firmness. The protruding mounting rod 14 can be removed or directly cut off during the subsequent polishing process.

[0032] In an optional embodiment, the first step groove 2 and the second step groove 4 have the same structure, the first step block 3 and the second step block 5 have the same structure, the first step groove 2 and the first step block 3 have the same width, and the first step groove 2 and the first step block 3 have the same height. Due to the above arrangement, the step groove and the step block fit together perfectly after splicing, thereby improving the overall structural strength.

[0033] It should be noted that glue needs to be applied during the splicing process.
