[0020] The utility model will be further explained in detail in combination with the drawings.

[0021] To solve the above technical problem, the technical scheme provided by the utility model is as follows: a wood dining chair splicing structure, in combination with the drawings, Figure 1 -, 2, including seat plate 4, and two long support rods 1 and short support rods 2 installed around seat plate 4 and supporting seat plate 4, respectively, the long support rods 1 and the short support rods 2 are both commonly provided with connecting rods 3, and a plurality of backrest rods 5 are commonly installed on the top of the long support rods 1, the seat plate 4 and each rod are assembled by the way of mutual clamping, but the current chair structure is not stable, by increasing a contraction frame under the chair, the two long support rods 1 are pulled tightly inward, so that the connecting parts of each part of the chair do not loosen, thereby providing the stability of the chair.

[0022] Wooden dining chairs are formed by assembling multiple rods and boards of various types together. Countersunk holes are drilled at appropriate positions on the seat 4, long support rod 1, and short support rod 2. The ends of the short support rod 2, connecting rod 3, and backrest rod 5 are also pre-cut with snap-fit ​​ends that fit into the countersunk holes. They are then inserted into each other in sequence to form the chair.

[0023] Combined with appendix Figure 3 A retractable frame is installed between the bottoms of the long support rods 1. The retractable frame includes a bracket 7 installed between the long support rods 1. Screw sleeves 8 are connected to both ends of the bracket 7. A screw rod 9 is internally threaded into the screw sleeve 8.

[0024] Combined with appendix Figures 4-5 The bottom of the long support rod 1 has a through hole, and a hole sleeve 6 is installed in the through hole. Both ends of the retractable frame extend to the outside of the hole sleeve 6 and are fitted with buckle plates 10 that are pressed inward close to the surface of the long support rod 1. The end of the screw rod 9 passes through the hole sleeve 6.

[0025] The screw 9 has a screw hole at its end. The buckle 10 is threaded to the screw hole by a bolt 11 passing through the buckle 10 from one side and is fixed to the end of the screw 9.

[0026] The bottom of the long support rod 1 is provided with locking holes 13 above and below the hole sleeve 6. The buckle plate 10 is connected to one side and is embedded in the locking holes 13 to provide a limiting condition for the screw 9 to move horizontally under the rotation of the bracket 7.

[0027] First, the screw 9 and the long support rod 1 are fixed by the buckle plate 10. In this way, when the bracket 7 rotates, the screw 9 in the screw sleeve 8 will not rotate with the bracket 7 and the screw sleeve 8, and will move towards the bracket 7. The two screws 9 are arranged in opposite directions according to the extension direction of the thread structure, so as to make the two long support rods 1 lock the various rods and plates to the maximum extent, without leaving any gaps that may loosen between them.

[0028] The buckle plate 10 is installed and fixed on the long support rod 1 and the screw rod 9 by means of buckles and studs, which makes it convenient to quickly install and remove anytime and anywhere, and will not damage the structure of the various components of the seat.

[0029] In practical implementation, all components of this wooden dining chair can be mass-produced using a standardized production method and can be easily disassembled without damaging the original structure. When assembling the chair, the various panels and rods are spliced ​​together to form the general shape of the chair. The screws 9 at both ends of the retractable frame are first extended by rotation and inserted into the hole sleeve 6. Then, the buckle plate 10 is installed on the screws 9 and the end of the hole sleeve 6 using bolts 11. At this time, the locking block 12 on the buckle plate 10 should be aligned with or already embedded in any of the locking holes 13 around the hole sleeve 6. After the above installation steps are completed, the hand support 7 is rotated. With the movement of the two screws 9, the buckle plates 10 on both sides of the chair press the long support rod 1 and other rods and panels inward, so that there will be no loosening at the joint of any two adjacent rods. If you want to remove the chair, simply reverse the above operation.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
