Description

Technical Field

[0001] This utility model belongs to the field of solid wood furniture technology, specifically a solid wood furniture splicing structure. Background Technology

[0002] The splicing structure of solid wood furniture tabletops is a core element affecting their mechanical properties, durability, and aesthetics. Traditional splicing techniques (such as flat splicing and finger splicing) directly connect narrow solid wood boards using adhesives, relying on the bonding force of the adhesive layer to achieve the joint. Due to differences in moisture content caused by the wood's absorption or drying, the ends are prone to warping or even cracking. The glued area is limited, and the adhesive layer is prone to aging after long-term use, leading to a decrease in the strength of the joint. This paper proposes a new splicing structure for solid wood furniture to solve these problems. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a solid wood furniture splicing structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solid wood furniture splicing structure, including a first splicing board, with a second splicing board spliced ​​to the bottom of the first splicing board; wherein, the first splicing board includes a first board material and guide blocks, a first tenon is arranged in an array on one side of the first board material, and the guide blocks are arranged in a linear array on the inclined surface of the first tenon; the second splicing board includes a second board material, a second tenon is arranged in a linear array on one side of the second board material, and glue guide grooves are provided on both inclined surfaces of the second tenon.

[0005] Preferably, both the first tenon and the second tenon are dovetail tenons, and two adjacent first tenons are engaged with a second tenon.

[0006] Preferably, the adhesive guide groove has a honeycomb-like structure.

[0007] Preferably, PUR environmentally friendly adhesive is injected and filled between the guide block and the adhesive guide groove, and the length of the long diagonal of the guide block is not greater than the width of the port of the adhesive guide groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention prevents the desktop end face from warping and cracking by using a first and second splicing plate together. By fitting the first and second tenons together, the guide block can slide between the glue guide grooves. Then, PUR environmentally friendly adhesive is injected into the glue guide groove from its port. The honeycomb structure of the glue guide groove evenly disperses the adhesive to the splicing surface through capillary action, avoiding local glue shortages. The guide block guides the adhesive to penetrate to the edge of the honeycomb unit, reducing glue accumulation in the center. The first and second tenons increase the contact area between the tenon and the mortise, improving tensile strength, preventing lateral displacement at the splice, forming multiple stress dispersion points, reducing the risk of stress concentration at a single joint, balancing adhesive bonding and mechanical connection, reducing dependence on adhesive performance, and preventing the desktop from warping and cracking.

[0011] 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.

[0012] like Figures 1 to 4 As shown, this utility model provides a solid wood furniture splicing structure, including a first splicing board 1, and a second splicing board 2 spliced ​​to the bottom of the first splicing board 1; wherein, the first splicing board 1 includes a first board 101 and a guide block 103, a first tenon 102 is arranged in an array on one side of the first board 101, and the guide block 103 is arranged in a linear array on the inclined surface of the first tenon 102; the second splicing board 2 includes a second board 201, a second tenon 202 is arranged in a linear array on one side of the second board 201, and a glue guide groove 203 is provided on both inclined surfaces of the second tenon 202.

[0013] Both the first tenon 102 and the second tenon 202 are dovetail joints. Two adjacent first tenons 102 are engaged with a second tenon 202. The adhesive guide groove 203 has a honeycomb structure. PUR environmentally friendly adhesive is injected and filled between the guide block 103 and the adhesive guide groove 203 to balance curing speed and bonding strength. The length of the long diagonal of the guide block 103 is not greater than the width of the port of the adhesive guide groove 203.

[0014] The above solution involves the following steps: by fitting the first tenon 102 and the second tenon 202 together, the guide block 103 can slide between the glue guide grooves 203. Then, PUR environmentally friendly adhesive is injected into the glue guide groove 203 from its port. The honeycomb structure of the glue guide groove 203 distributes the adhesive evenly to the splicing surface through capillary action, avoiding local glue shortages. The guide block 103 guides the adhesive to penetrate to the edge of the honeycomb unit, reducing the accumulation of adhesive in the center. The first tenon 102 and the second tenon 202 increase the contact area between the tenon and the mortise, improving tensile strength, preventing lateral displacement at the splicing point, forming multiple stress dispersion points, reducing the risk of stress concentration at a single joint, balancing adhesive bonding and mechanical connection, reducing dependence on adhesive performance, and preventing the tabletop from warping and cracking.
