一种竹制品的榫卯拼接结构
By combining a central disc, a rotating connecting rod, and a sealing strip, along with a mortise and tenon joint and a tension spring structure, the problem of the inability to adjust the angle of mortise and tenon joints in bamboo products is solved. This achieves flexible angle adjustment and a highly stable connection, making it suitable for various applications of bamboo products.

AI Technical Summary
Existing bamboo products have a fixed mortise and tenon joint structure, which makes it difficult to adjust the angle and limits the use of the products in different scenarios, such as bamboo brackets that can flexibly change angles and the functional expansion of foldable bamboo products.
The design employs a combination of a central disc, a rotating connecting rod, and a sealing strip, along with a tenon and mortise slot and a tension spring structure. This allows for flexible rotation and angle adjustment of the rotating connecting rod. Furthermore, the precise matching of the tenon and mortise blocks with the tenon and mortise slots, along with the elastic clamping mechanism, enhances the stability of the connection.
It enables precise adjustment and stable connection of bamboo product folding angles, ensuring both rotational flexibility and enhanced connection stability, preventing loosening and the entry of dust and moisture, and simplifying the assembly and disassembly process.

Abstract
Claims
1. A mortise and tenon joint structure of a bamboo product, comprising: The central disc (1) is characterized in that there are two sets of central discs (1) arranged opposite to each other, and a connecting rod (2) is fixed between the two sets of central discs (1). A locking groove (3) is opened on the inner side of the central disc (1). A rotating connecting rod (4) is locked inside the locking groove (3). A connecting strip (5) is fixed on one side of the rotating connecting rod (4). A connecting main plate (6) is inserted into the other end of the connecting strip (5).
2. The mortise-and-tenon joint structure of a bamboo product according to claim 1, wherein, A sealing strip (14) is fixed to the other side of the rotating connecting rod (4). The ring diameter of the locking groove (3) is adapted to the combined cross-sectional specifications of the rotating connecting rod (4) and the sealing strip (14) so that the rotating connecting rod (4) and its connecting structure can rotate flexibly around the connecting rod (2) and control its angle. The inner side of the sealing strip (14) is tightly attached to the connecting rod (2) to achieve relative sealing between the two.
3. The mortise-and-tenon joint structure of a bamboo product according to claim 1, wherein, The connecting strip (5) has a tenon and mortise slot (7) on one side. Several sets of tenon and mortise blocks (8) are fixed inside the tenon and mortise slot (7). A tenon and mortise insert (9) is fixed at one end of the connecting main board (6). The tenon and mortise insert (9) is compatible with the specifications of the tenon and mortise slot (7). Several sets of tenon and mortise grooves (10) are evenly opened through the tenon and mortise insert (9). The number and specifications of the tenon and mortise grooves (10) are compatible with the number and specifications of the tenon and mortise blocks (8).
4. The mortise-and-tenon joint structure of a bamboo product according to claim 3, wherein, The connecting strip (5) has a movable slot (11) that runs through the tenon and mortise slot (7) on one side. Several sets of tension springs (12) are evenly fixed to one side inside the movable slot (11), and the other end of the several sets of tension springs (12) is fixed to the same set of movable pressure plates (13).
5. The mortise-and-tenon joint structure of a bamboo product according to claim 4, wherein, The movable pressure plate (13) is set close to the tenon block (8), and under the continuous tension of the tension spring (12), it remains close to the tenon block (8) to fix the connection between the tenon slot (7) and the tenon insert (9).
6. The mortise-and-tenon joint structure of a bamboo product according to claim 1, wherein, The center disk (1) has a positioning groove (15) at the center of its top surface. A positioning plate (16) is embedded inside the positioning groove (15). A spring groove (17) is opened at the center of the bottom surface of the positioning groove (15). A tension spring (18) is fixedly connected to the bottom surface inside the spring groove (17). The top of the tension spring (18) is fixedly connected to the center of the bottom surface of the positioning plate (16).
7. The mortise-and-tenon joint structure of a bamboo product according to claim 6, wherein, The bottom surface of the positioning circular plate (16) is fixed with several sets of evenly arranged positioning blocks (19), and the bottom surface of the positioning circular groove (15) is provided with several sets of positioning slots (20). Under the action of the tension spring (18), the positioning blocks (19) are stably inserted into the positioning slots (20) along with the structure of the positioning circular plate (16).
8. The mortise-and-tenon joint structure of a bamboo product according to claim 7, wherein, The rotating connecting rod (4) has a connecting rod positioning groove (21) structure at the top and bottom center. The positioning block (19) is inserted into the positioning slot (20) along with the positioning round plate (16). The end of the corresponding positioning block (19) can be inserted into the connecting rod positioning groove (21) to fix the included angle between the rotating connecting rods (4) or the angle relative to the central disk (1).
