[0002] Four-legged solid wood tables are widely used in our lives, such as dining tables used in homes and restaurants, as well as negotiation tables and conference tables used in offices. At present, most solid wood tables on the market are lower leg + frame structures, and the connection forms are mostly divided into two types: integrated and split. The integrated type has good strength and stable structure, but the packaging volume is large and the transportation cost is high; the split type is divided into three parts: tabletop + frame + lower leg, which are connected by screws. The overall packaging volume is small and the transportation cost is low, but the stability of the connection between the table legs and the frame is difficult to solve; in addition, most of its frames are connected by four legs through diagonal pull bars with nails or screws, and the exposed screws are not beautiful and easy to cause rust problems.
[0003] Based on the above technical defects, the present application provides a new solid wood table with mortise and tenon structure. Utility Model Content
[0004] The utility model aims to provide a novel solid wood table with a mortise and tenon structure, in which the legs and the frame are spliced by designing a mortise and tenon structure inside the inclined stay.

[0023] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.
[0024] like Figure 1-Figure 3 As shown, a novel mortise and tenon structure solid wood table includes a tabletop frame 10, a tabletop board 20 and a plurality of legs 30 arranged circumferentially around the tabletop frame 10. The tabletop frame 10 includes a plurality of beams 11 enclosed end to end. Two adjacent beams 11 are mortised by diagonal bars 13, and a gap 14 is left between the adjacent beams 11. The legs 30 are fixed to the diagonal bars 13 after passing through the gap 14. Specifically, slots 12 are provided at the two end positions of the beam 11, and tenons 131 mortised with the slots 12 are provided at both ends of the diagonal bars 13. In the present application, the slots 12 are preferably designed as inverted trapezoidal blind holes, and the tenons 131 are inverted trapezoidal protrusions that cooperate with the slots 12.
[0025] It can be understood that the desktop frame 10 is formed by the mortise and tenon joints of the crossbeam 11 and the bevel 13, which not only has a simple structure, a concise and beautiful appearance, and reliable strength, but also saves the screw process, is quick to install, and avoids problems such as screw rust during use.
[0026] The first inclined surface 15 is provided at both ends of the crossbeam 11. The leg 30 includes a support rod 31 and a connecting rod 32. One end of the connecting rod 32 is fixed to the top of the support rod 31; the other end is provided with a gap 14 to be plugged and matched with two adjacent crossbeams 11, and its two side walls are fitted with the first inclined surface 15 provided at the ends of the adjacent crossbeams 11. The two side walls where the connecting rod 32 fits with the first inclined surface 15 are provided with a second inclined surface 321, and the second inclined surface 321 fits with the first inclined surface 15. The first inclined surface 15 is preferably an inverted 48° inclined surface, and the second inclined surface 321 is preferably an inverted 3° inclined surface. That is, the end of the crossbeam 11 and the connecting rod 32 cooperate through the inclined surface (the first inclined surface 15 and the second inclined surface 321), which has a locking effect of tightening, can solve the problem of poor fitting gap caused by processing errors, and the overall structure is stable. In the present application, a fixing hole 132 is provided on the inclined block 13, and the rear end of the connecting rod 32 passing through the gap 14 is fixed with the fixing hole 132 by screws.
[0027] In addition, a countersunk hole is provided at the bottom of the desktop panel 20, and a through hole 16 corresponding to the countersunk hole is provided on the cross beam 11. The through hole 16 and the countersunk hole cooperate with screws to fix the desktop panel 20 and the cross beam 11. The screw is inserted into the through hole 16 from the lower end surface of the cross beam 11 and fixed to the countersunk hole. In this way, the screw can be better hidden, and no trace of connection can be seen on the desktop panel 20. In order to improve the overall utilization rate and reduce the processing cost, the desktop panel 20, the cross beam 11, and the inclined rail 13 of the present application are processed from the same plate. Example
[0028] Continue reading Figure 1-Figure 3In one embodiment, the desktop frame 10 includes four beams 11 enclosed end to end and four legs 30 arranged at the connection between two beams 11, the four beams 11 include two long beams and two short beams, and the two long beams and the two short beams form a rectangular structure; two adjacent beams 11 are mortise-jointed by an oblique block 13, and a gap 14 is left between the adjacent beams 11, and the legs 30 are fixed to the oblique block 13 after passing through the gap 14.
[0029] In this embodiment, the crossbeam 11 is made of finger-jointed wood strips with a cross-sectional size of 60*25mm, which is consistent with the material of the desktop board 20, so that the utilization rate of the produced and processed board is higher; a slot 12 (inverted trapezoidal blind hole) is opened on the crossbeam 11 at 25mm from both ends, and the hole depth is 40mm, and two inverted trapezoidal tenons 131 extend from both ends of the inclined rail 13, which are consistent with the size and depth of the inverted trapezoidal blind holes of the crossbeam 11 (such as Figure 2 As shown), when the crossbeam 11 cooperates with the oblique piece 13, glue is first injected into the inverted trapezoidal blind hole of the crossbeam 11, and then the tenon 131 of the oblique piece 13 is inserted into the inverted trapezoidal blind hole, thus completing the connection of the desktop frame 10.
[0030] A first inclined surface 15 with an inverted angle of 48° is provided at the end of the cross beam 11, and a second inclined surface 321 with an inverted angle of 3° is provided at the connection point between the connecting rod 32 of the support leg 30 and the cross beam 11, so as to facilitate the insertion of the connecting rod 32 between two adjacent cross beams 11; a fixing hole 132 is provided on the inclined block 13, and a screw is connected to the end of the connecting rod 32. When the screw is tightened, the inclined surface (the first inclined surface 15 and the second inclined surface 321) is introduced, so that the connection between the support leg 31 and the cross beam 11 can be tightened more firmly (such as Figure 3 As shown), finally the desktop panel 20 is connected to the desktop frame 10 (ie, the crossbeam 11) by screws.
[0031] The overall design of the solid wood table of the present application is simple and practical, efficient to install, low cost, good stability, and good appearance.
