[0027] Among them, a groove 21 is provided on the expansion plate 2 at a position corresponding to the self-locking buckle, so that when the expansion plate 2 is connected to the drum leg 1 by mortise and tenon from top to bottom, the part of the self-locking buckle 16 extending out of the groove 12 is just stuck in the groove 21, and the top of the expansion plate 2 is flush with the top of the connecting part 14.
[0028] In the above technical scheme, the mortise and tenon structure for wooden materials includes a drum leg 1 and a swelling board 2 used together. The appearance of the drum leg 1 is like the appearance of a drum, which is both beautiful and tensile. A connecting surface is provided on the top of the drum leg 1. Preferably, the connecting surface is inclined, and the inclination angle of the connecting surface is preferably 45°. A connecting portion 14 and a mortise 11 are provided in parallel on the connecting surface. The bottom of the connecting portion 14 is an inclined surface consistent with the inclination angle of the connecting surface. A pair of corner tenons are provided on the top of the connecting portion 14, namely a first corner tenon 15 and a second corner tenon 13. The first corner tenon 15 and the second corner tenon 13 are respectively arranged at the diagonals of the top of the connecting portion 14. A pair of corner tenons are used to lock the face edge and the dock. The connecting portion 14 is provided on the side close to the mortise 11. The groove 12 is used to set a self-locking buckle 16, a part of the self-locking buckle 16 is inserted into the groove 12, and a part of the self-locking buckle 16 extends out of the groove 12. The part of the self-locking buckle 16 extending out of the groove 12 is used to clamp the slot 21 set on the expansion plate 2. The mortise 11 is used to connect the tenon 22 adapted on the expansion plate 2. When the expansion plate 2 is vertically connected to the drum leg 1 from top to bottom, the tenon 22 is inserted into the mortise 11, the part of the self-locking buckle 16 extending out of the groove 12 is just clamped with the slot 21, and the top of the expansion plate 2 is flush with the top of the connecting part 14; the end of the expansion plate 2 is provided with a connecting end that cooperates with the connecting surface of the drum leg 1, that is, the connecting end has at least an inclined portion adapted to the inclination angle of the connecting surface, such as Figure 1 As shown, the outer side of the tenon 22 (the side away from the connecting portion is the outer side) has an inclined portion adapted to the connecting surface. In order to ensure the firmness of the root of the drum leg 1, the mortise 11 cannot penetrate the drum leg 1 in the vertical direction.
[0029] In the above technical solution, if Figure 1 As shown, the wooden material is connected by a mortise and tenon structure including a drum leg 1 and an expansion plate 2, wherein the drum leg 1 is provided with the expansion plate 2. According to the structure of a drum leg 1 and an expansion plate 2 connected disclosed in the present application, a person skilled in the art can easily think of a structure of a drum leg 1 and two expansion plates 2 connected, the two expansion plates 2 are perpendicular to each other and both expansion plates 2 are perpendicular to the drum leg 1. On the basis of the present application, as long as the shape of the connecting portion 14 is changed to an irregular shape, mutually perpendicular mortises 11 are provided on both sides of the connecting portion 14, and one side of the connecting portion 14 close to any mortise 11 is respectively parallel to the closest mortise 11, and the remaining part of the connecting portion 14 is adapted to the shape of the drum leg 1.
[0030] In the above technical solution, the assembly of the mortise and tenon structure for wooden materials requires two processes. The first step is to fix the self-locking buckle 16 in the groove 12, and the second step is to insert the tenon 22 of the expansion board 2 into the mortise 11. At this time, the part of the self-locking buckle 16 extending out of the groove 12 is just stuck in the slot 21 on the expansion board 2, while the traditional drum leg expansion structure requires 6 processes to assemble, which simplifies the process of the drum leg expansion structure and facilitates operation. In the traditional drum leg expansion structure, the self-locking buckle 16 is fixed with the slot 21 on the expansion board 2, and the self-locking buckle 16 is vertically arranged with the mortise 11, so that the two fixing structures are vertical, which increases the firmness and durability of the wooden mortise and tenon structure.
[0031] like Figure 1 As shown, in one of the technical solutions, the self-locking buckle 16 includes an integrally formed trapezoidal portion and a dovetail portion, the trapezoidal portion gradually widens from top to bottom and has a trapezoidal cross-section in the vertical direction, and the trapezoidal portion is inserted into the groove. The self-locking buckle 16 includes an integrally formed trapezoidal portion and a dovetail portion, the trapezoidal portion is fixed in the groove 12, and the dovetail portion is arranged outside the groove 12, so that the dovetail portion of the self-locking buckle 16 and the slot 21 form a dovetail tenon structure, further increasing the strength and durability of the structure.
[0032] exist Figure 1 In one of the technical solutions, a notch extending inward from the trapezoidal portion is provided at the bottom of the self-locking buckle 16, the notch gradually narrows in the direction extending inward from the trapezoidal portion and has a trapezoidal cross-section in the vertical direction, and a matching permanent expansion wedge 17 is provided at the notch, so that the self-locking buckle 16 is firmly fixed to the groove 12, and a step is added in the assembly process of the mortise and tenon structure for wooden materials. First, a part of the permanent expansion wedge 17 is inserted into the notch, and then the self-locking buckle 16 is slowly knocked into the groove 12. The permanent expansion wedge 17 gradually tightens as it gradually penetrates into the notch.
[0033] Depend on Figure 1 It can be seen that in one of the technical solutions, the shape of the groove 21 is adapted to the dovetail portion, and the groove 21 penetrates the expansion board 2 in the thickness direction of the expansion board 2 to ensure that the groove 21 just accommodates the dovetail portion of the self-locking buckle 16, that is, after the dovetail portion is clamped in the groove 21, the dovetail portion does not protrude from the side of the expansion board 2.
[0034] from Figure 1 It can be seen that in one of the technical solutions, the connecting portion 14 is integrally formed with the drum leg 1, and the pair of corner tenons are of different heights, which are used to lock the face edge and the dock.
[0035] like Figure 1As shown, in one of the technical solutions, the connecting surface is tilted at an angle of 45°, and the structure is smoother.
[0036] exist Figure 1 In one of the technical solutions, the mortise 11 does not penetrate the drum leg 1 , thereby ensuring the firmness of the root of the drum leg 1 .
