Technical Field
[0001] This utility model belongs to the field of furniture technology, and in particular relates to a connection structure for wooden furniture. Background Technology
[0002] As people's living standards continue to improve, their aesthetic and functional demands for furniture are becoming increasingly diverse. Wooden furniture, due to its natural, environmentally friendly, and durable advantages, has always been favored by consumers. Especially in Neo-Chinese and Scandinavian style home design, wooden furniture, with its simple lines, natural textures, and rustic feel, has become an important element in creating spatial atmosphere. Neo-Chinese style furniture emphasizes the combination of tradition and modernity, highlighting structural stability and elegant form; while Scandinavian style furniture pursues minimalism and functionality, focusing on the original beauty and practicality of wood.
[0003] However, traditional wooden furniture assembly often relies on screws, nails, glue, and other auxiliary connectors or adhesives. While these methods achieve the connection of components, they also have some significant drawbacks. First, using metal connectors like screws and nails not only damages the natural beauty of the wood but may also lead to loosening and rusting over long-term use, affecting the stability and lifespan of the furniture. Second, while adhesives like glue can achieve seamless connections, they pose environmental concerns and are very inconvenient for disassembly or repair. Furthermore, traditional connection methods typically require specialized tools and skills, increasing the difficulty and cost of furniture assembly and repair.
[0004] To address these issues, we provide a connection structure for wooden furniture. Utility Model Content

Specific Implementation Example 1
[0050] Please see Figure 1-13 This utility model is a connection structure for wooden furniture, including a tabletop 1, with fixing grooves 2 on all four sides of the tabletop 1, and fixing blocks 3 movably connected inside the fixing grooves 2; a connecting plate 4 is fixed to one side of the fixing block 3, and a table leg 5 is fixed to one side of the connecting plate 4; a first positioning groove 6 is opened on one side of the fixing block 3, and a second positioning groove 7 is opened on each side of the tabletop 1; positioning blocks 8 are movably connected inside both the first positioning groove 6 and the second positioning groove 7; a placement groove 9 is opened on one side of the second positioning groove 7, and an adjustment groove 10 is opened at the bottom of both the placement groove 9 and the connecting plate 4; a handle 11 is slidably connected inside the adjustment groove 10, and a push plate 12 is fixed to one side of the handle 11, the push plate 12 matching the inner wall of the placement groove 9; the handle 11 passes through the adjustment groove 10.
[0051] Specifically, the first positioning groove 6 and the second positioning groove 7 are both "T" shaped structures, and the positioning block 8 is an "I" shaped structure; a number of first reinforcing strips 13 are fixed on the outside of the positioning block 8, and the first reinforcing strips 13 are made of rubber material.
[0052] Furthermore, both the first positioning groove 6 and the second positioning groove 7 have a slot 14 on one side, and a card plate 15 is fixed on one side of the positioning block 8; the card plate 15 matches the slot 14; the fixing block 3 has an "L" shaped structure and matches the inner wall of the fixing groove 2.
[0053] The operation process of this embodiment is as follows: Connect the table leg 5 to the fixing block 3 through the connecting plate 4, align the fixing grooves 2 around the tabletop 1, and insert the fixing block 3 into the fixing grooves 2 to initially fix the table leg 5 to the edge of the tabletop 1; align the first positioning groove 6 on the side of the fixing block 3 with the second positioning groove 7 on the side of the tabletop 1, and insert the "I"-shaped positioning block 8 into both; the rubber first reinforcing strip 13 on the outside of the positioning block 8 will make close contact with the inner wall of the first positioning groove 6 to increase friction and prevent loosening; when it is necessary to disassemble the tabletop 1 and the table leg 5, first push the handle 11 in the adjusting groove 10 to drive the push plate 12 to slide in the placement groove 9, and the push plate 12 will press the positioning block 8 to move it towards the slot 14 until the positioning block 5 is fixed. By pushing out the first positioning groove 6 and the second positioning groove 7 from one side of the positioning block 8, the positioning block 8 can be removed. Then, the tabletop 1 can be lifted up to separate the tabletop 1 from the table leg 5. This device enables the tabletop 1 and table leg 5 to be assembled and connected.
