[0025] 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.

[0026] like Figures 2 to 7 As shown, this embodiment discloses a dining chair, including a wooden stool 1 and a backrest 4. The stool 1 and the backrest 4 are connected by a metal frame. A support leg 2 is fixed to the lower part of the stool 1. The metal frame includes a first connecting piece 5 and a second connecting piece 6. The first connecting piece 5 is connected to the upper part of the stool 1, specifically, the first connecting piece 5 is connected to the stool 1 by a bolt 8. A connector 7 corresponding to the bolt 8 is embedded inside the stool 1. The stool 1 has a mounting groove 11 corresponding to the connector 7 inside. The connector 7 is located in the mounting groove 11 and its upper part abuts against the upper part of the mounting groove 11. The bolt 8 is threadedly connected to the connector 7. The connector 7 includes a threaded groove 71. The lower end of the bolt 8 is inserted into and threadedly connected to the threaded groove 71 to fix the first connecting piece 5 and the seat 1. The second connecting piece 6 is connected to the lower part of the backrest 4. The lower part of the backrest 4 is provided with a limiting groove 41. The second connecting piece 6 is embedded in the limiting groove 41. The second connecting piece 6 and the backrest 4 are fixed by screws. The first connecting piece 5 and the second connecting piece 6 are connected by multiple connecting rods 3. The connecting rods 3 are welded and fixed to the first connecting piece 5 and the second connecting piece 6 respectively. Figure 4As shown, by embedding a metal connector 7 inside the stool 1, the metal frame and the stool 1 are fixed together by the bolt 8 and the connector 7. When the bolt 8 is subjected to an upward force, the bolt 8 has higher locking reliability because the connector 7 is made of metal. Even if the user sits on it repeatedly, the bolt 8 will not loosen. Furthermore, since the upper part of the connector 7 abuts against the upper part of the mounting groove 11, even if the bolt 8 is subjected to force, the connector 7 will not be pulled upward, resulting in good reliability.

[0027] like Figure 4 As shown, a plug 9 is fixed in the mounting groove 11. The upper part of the plug 9 abuts against the lower part of the connector 7. The lower contour of the plug 9 is consistent with the outer contour of the stool 1. By setting the plug 9, the mounting groove 11 can be covered, making the stool 1 look more beautiful.

[0028] like Figure 4 As shown, when the mounting groove 11 has a circular cross-section, the outer wall of the connector 7 is adapted to the inner wall of the mounting groove 11. The lower part of the connector 7 has a hexagonal groove 72. In this structure, when connecting the bolt 8 and the connector 7, an internal hex wrench needs to be inserted from the mounting groove 11 into the hexagonal groove 72, and then the bolt 8 is tightened by the hex wrench to achieve fixation. Using an internal hex wrench can prevent the connector 7 from moving when tightening the bolt 8. The circular mounting groove 11 is easy to process. With this structure, if the dining chair needs to be disassembled later, If the chair needs to be disassembled, the plug 9 can be made of rubber. When the chair needs to be disassembled, simply remove the plug 9 to easily remove the bolt 8. If the chair does not need to be disassembled after it is made, the plug 9 can be made of wood, the same as the seat 1. After the bolt 8 is installed, apply glue to the plug 9 and insert it into the mounting groove 11. Then, polish the outer surface of the seat 1 so that the outer contour of the plug 9 matches the outer contour of the seat 1. Finally, paint the seat 1. The seat 1 will have a higher overall appearance after painting.

[0029] like Figure 4 As shown, when the cross-section of the mounting groove 11 is not circular, that is, when the cross-section of the mounting groove 11 is hexagonal, the outer wall of the connector 7 is adapted to the inner wall of the mounting groove 11. At this time, the outer wall of the connector 7 is also hexagonal. The processing of the hexagonal mounting groove 11 is more difficult than that of the circular mounting groove 11. However, since the mounting groove 11 is hexagonal, the bolt 8 can be directly connected to the connector 7, and the connector 7 will not slip during the connection. With this structure, the connector 7 can be embedded in the mounting groove 11 when the stool 1 is made, and the mounting groove 11 can be blocked by the wooden plug 9. The bolt 8 can also be removed later.

[0030] Among them, such as Figure 4 , Figure 5 and Figure 7As shown, the upper end of the bolt 8 is located inside the connecting rod 3. Specifically, the connecting rod 3 includes a hollow rod 31 corresponding to the bolt 8, with the head of the bolt 8 located inside the hollow rod 31. The lower end of the hollow rod 31 abuts against the upper part of the first connecting piece 5. The second connecting piece 6 includes a clearance hole 61 corresponding to the hollow rod 31. The hollow rod 31 passes through the clearance hole 61 and its upper end abuts against the lower part of the backrest 4, that is, the upper end of the hollow rod 31 abuts against the upper part of the limiting groove 41. The connecting rod 3 also includes a plurality of solid rods 32. At least one solid rod 32 is provided between two adjacent hollow rods 31. The lower end of the solid rod 32 is welded and fixed to the upper part of the first connecting piece 5, and the upper end of the solid rod 32 is welded and fixed to the lower part of the second connecting piece 6.

[0031] The first connecting piece 5 and the second connecting piece 6 are connected by a solid rod 32 to form an integral structure, thereby ensuring the structural strength of the metal frame. The hollow rod 31 serves a decorative purpose, making the metal frame more integrated. Furthermore, through the interaction between the hollow rod 31 and the plug 9, the bolt 8 can be hidden, making the dining chair more integrated and improving its aesthetics. After the structure formed by the first connecting piece 5, the second connecting piece 6, and the solid rod 32 is fixed to the seat 1 by the bolt 8, the hollow rod 31 is then inserted from top to bottom through the clearance hole 61 and abutted against the upper part of the first connecting piece 5. After the hollow rod 31 is installed, the backrest 4 is then connected and fixed to the second connecting piece 6.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
