[0024] 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.
[0025] Please see Figures 1 to 5 This utility model provides an embodiment of a detachable mortise and tenon structure for solid wood furniture, including a wooden beam A100, a wooden beam B200, a plug 300, and a round rod 400. The wooden beams A100 and B200 are joined at opposite ends and are perpendicular to each other. A slot A101 is provided at the top of one end of the wooden beam A100, and a slot B201 is provided at the top of one end of the wooden beam B200. The bottoms of slots A101 and B201 are sealed. After being joined, slots A101 and B201 are connected. The plug 300 can be inserted into the connected slots A101 and B201. The cross-section of the plug 300 is hourglass-shaped, and the plug 300 is adapted to the connected slots A101 and B201. Wooden beams A100 and B200 are fixed by inserting the insert 300 into the connected slots A101 and B201, using a mortise and tenon joint.
[0026] A through hole A104 is provided on the wooden beam A100 at the bottom of slot A101, and a through hole B204 is provided on the wooden beam B200 at the bottom of slot B201. Through holes A104 and B204 are connected when joined together. A round rod 400 can be inserted into the connected through holes A104 and B204, and the round rod 400 engages with the inserted plug 300. When disassembling wooden beams A100 and B200, the round rod 400 is inserted into the corresponding connected through holes A104 and B204. Workers then use a hammer to strike the round rod 400, which pushes the inserted plug 300 out of the connected slots A101 and B201.
[0027] This utility model, by setting through holes A104, through holes B204 and round rod 400, has the advantage of using an ejection method to push out the inserted block 300, which facilitates the disassembly of wooden beams A100 and B200. It solves the problem that it is difficult to remove the inserted structure during disassembly of the insert-type mortise and tenon structure, and the disassembly process is relatively troublesome.
[0028] Specifically, one end of wooden beam A100 has a slot C102, and one end of wooden beam B200 has an insert 202, which can be inserted into slot C102. Insert 202 has a trapezoidal cross-section and is adapted to fit slot C102. When wooden beams A100 and B200 are joined, the inclined surfaces at opposite ends of wooden beams A100 and B200 are misaligned, and insert 202 is inserted into slot C102 accordingly, ensuring a stable connection between wooden beams A100 and B200.
[0029] This utility model, by setting a slot C102 and an insert 202, has the advantage that after wooden beams A100 and B200 are joined, the insert 202 is inserted into the slot C102 for limiting, so that the wooden beams A100 and B200 remain stably joined.
[0030] The middle section of insert 202 is broken, and the break in the middle section of insert 202 is consistent with the connected slots A101 and B201. The insertion of insert 202 and slot C102 does not affect the insertion of insert 300 into the connected slots A101 and B201.
[0031] Furthermore, an embedding hole A103 is provided on the inner side of one end of the wooden beam A100, and an embedding hole B203 is provided on the inner side of one end of the wooden beam B200. The two ends of the round rod 400 are respectively inserted into the embedding hole A103 and the embedding hole B203, and a triangular structure is formed on the inner side of the joint between the round rod 400 and the wooden beams A100 and B200.
[0032] This utility model, by setting embedding holes A103 and B203, has the advantages of placing a round rod 400 after the wooden beams A100 and B200 are fixed, the round rod 400 can be used at any time, and the triangular structure formed on the inner side of the joint between the round rod 400 and the wooden beams A100 and B200 enhances the stability of the joint between the wooden beams A100 and B200.
[0033] Working principle: The inclined surfaces of wooden beams A100 and B200 are misaligned and joined together. Insert 202 is inserted into slot C102 until the inclined surfaces of wooden beams A100 and B200 are in complete contact. Insert 300 is inserted into slots A101 and B201. The two ends of the round rod 400 are inserted into the embedding holes A103 and B203 respectively.
[0034] When disassembling wooden beams A100 and B200, remove the round rod 400 and insert it into the corresponding through holes A104 and B204. The workers then use a hammer to strike the round rod 400, which pushes the inserted block 300 out of the connected slots A101 and B201. Then, the wooden beams A100 and B200 are disassembled.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
