DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] Please refer to Figure 1-5The detachable mortise and tenon connection structure of solid wood furniture comprises a table board 1, a mortise and tenon block 2 is fixedly installed on the lower surface of the table board 1, a table leg 3 is movably installed on the lower surface of the table board 1, a mortise and tenon hole 4 is provided on the upper surface of the table leg 3, a rotating column 5 is movably installed on the inner wall of the table leg 3, a semicircular arc plate 6 is fixedly installed on the outer surface of the rotating column 5, a handle 7 is fixedly installed on the outer surface of the rotating column 5, a groove 8 is provided on the front surface of the table leg 3, a buckle 9 is provided on the upper surface of the handle 7, a torsion spring 10 is fixedly installed on the inner wall of the table leg 3, a push column 11 is movably installed on the inner wall of the mortise and tenon hole 4, a clamping block 15 is fixedly installed on the upper end of the groove 8, the left end of the torsion spring 10 is fixedly connected to the right surface of the handle 7, the size of the clamping block 15 matches the size of the buckle 9, the size of the mortise and tenon block 2 matches the size of the mortise and tenon hole 4, and the size of the groove 8 matches the size of the handle 7.

[0022] In this embodiment: table legs 3 are movably mounted on the lower surface of the table top 1 .

[0023] Specifically: there are four table legs 3.

[0024] In this embodiment, the size of the groove 8 matches the size of the handle 7 .

[0025] Specifically: In this way, the handle 7 can be embedded into the groove 8, thereby increasing the overall aesthetics of the furniture.

[0026] Working principle: when the table leg 3 needs to be installed, the mortise and tenon block 2 is directly installed by aligning it with the mortise and tenon hole 4. When it needs to be disassembled, first pull the buckle 9, turn the handle 7, take the handle 7 out of the inner wall of the groove 8, and continue to turn the handle 7. At this time, the handle 7 rotates to drive the rotating column 5 to rotate, and the rotating column 5 rotates to drive the semi-circular plate 6 to rotate. When the semi-circular plate 6 rotates, its high point gradually contacts the push column 11, thereby pushing the push column 11 to move upward, and the push column 11 moves upward to be stuck in the mortise and tenon hole 4 is pushed upward until the table top 1 can be easily taken down, and then the rotation is stopped. When the rotating column 5 is rotating, the torsion spring 10 is also rotating. After the rotation is completed, the torsion spring 10 pushes the rotating column 5 to rotate due to its own resilience, thereby preventing the handle 7 from falling directly. Compared with the related art, the detachable mortise and tenon connection structure of solid wood furniture provided by the utility model has the following beneficial effects: the design can realize the effect of convenient disassembly of the table top 1 and the table leg 3, without manual labor or the need to use tools to disassemble them, saving time and labor.

[0027] Embodiment 2:

[0028] Please refer to Figure 1-5A fixed plate 12 is fixedly installed on the outer surface of the mortise and tenon hole 4, a movable plate 13 is fixedly installed on the outer surface of the push column 11, a spring 14 is fixedly installed on the adjacent surface of the movable plate 13 and the fixed plate 12, and the left and right surfaces of the movable plate 13 are movably connected to the inner wall of the table leg 3.

[0029] In this embodiment, a spring 14 is fixedly mounted on the adjacent surfaces of the movable plate 13 and the fixed plate 12 .

[0030] Specifically: two springs 14 are provided.

[0031] Working principle: when the push column 11 pushes the mortise and tenon block 2, the movable plate 13 moves upward with the push column 11, thereby squeezing the spring 14, and the spring 14 contracts. When the push column 11 completes its work, the upward thrust of the push column 11 disappears. At this time, the spring 14 pushes the push column 11 downward due to its own resilience, and the push column 11 is reset. Compared with the related art, the detachable mortise and tenon connection structure of solid wood furniture provided by the utility model has the following beneficial effects: the design can achieve the effect of resetting the push column 11, avoiding the situation where the push column 11 remains in the mortise and tenon hole 4 during the next installation, causing inconvenience to the installation.

[0032] The controller is an existing structure, and the control circuit can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.
