Specific embodiment

Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of supporting structure and desk for furniture, including One brace 1 and the second brace 2 are provided with tongue-and-groove A11 of the connection at left and right sides of it, 2 bottom surface of the second brace on first brace, 1 top surface On be provided with connection its at left and right sides of tongue-and-groove B21, tongue-and-groove A11 width and the second brace 2 are of same size, tongue-and-groove B21 width and First brace 1 is of same size, when tongue-and-groove A11 bottom wall is fastened on tongue-and-groove B21 bottom wall, the first brace 1 and 2 phase of the second brace Mutually intersect to cooperate together and forms supporting structure.

Using the technical solution of the utility model, when the supporting structure to be used in furniture, due to the first brace and Two braces all play supporting role to support, to increase considerably the bearing capacity of supporting structure, the first brace with Intersected mating connection between second brace using corresponding tenon groove structure, effectively prevent the first brace or the second brace it Between relative torsion, sliding, when keeping the stability of supporting structure higher, and making the supporting structure of the utility model, without Fourth of the twelve Earthly Branches head is processed in first brace or the second brace, it is only necessary to process corresponding tongue-and-groove, the processing technology thereof of tongue-and-groove is opposite Simply, thus manufacture craft is simplified, shortens production working hour, reduces assembling difficulty.In addition, the utility model additionally provides A kind of desk of the application supporting structure has many advantages, such as that assembling is simple, bearing capacity is strong, structural stability and good reliability.

Further, it is preferable to which tongue-and-groove A11 depth is the half of 1 height of the first brace, tongue-and-groove B21 depth is the second support The half of 2 height of arm.Tongue-and-groove A11 width and tongue-and-groove B21 are of same size.Middle die joint on tongue-and-groove A11 between two sidewalls It coincides with die joint in 1 rear and front end of the first brace.Before middle die joint and the second brace 2 on tongue-and-groove B21 between two sidewalls Die joint coincides in both ends afterwards.First brace, 1 length direction intersects vertically with 2 length direction of the second brace.First brace 1 with Carpenter's glue is also coated between second brace, 2 junction.First brace 1, the second brace 2 material be timber.First brace 1 It is identical as 2 length of the second brace.Using the technical solution of the utility model, the first brace 1 and 2 appearance profile of the second brace are basic Unanimously, to keep the bearing capacity of entire supporting structure everywhere more uniform, attractive appearance.

Further, chamfer angle A12,2 bottom surface of the second brace are provided between 1 bottom surface of the first brace and its rear and front end face Chamfer angle B22 is provided between its rear and front end face.It is preferred that chamfer angle A12 is relative to the inclination angle between 1 bottom surface of the first brace Less than 10 °, chamfer angle B22 relative to or 2 bottom surface of the second brace between inclination angle less than 10 °.Using the technology of the utility model Scheme keeps the shape of the supporting structure more attractive and generous, and when chamfer angle A12 and chamfer angle B22 is relative between its bottom surface Inclination angle less than 10 ° when, when weight is placed on the supporting structure, be conducive to the weight for generating weight to the supporting structure Power guides the carrying pressure that supporting structure edge is reduced to the center of gravity of supporting structure, to keep supporting structure more stable With it is reliable.

In addition, as shown in Fig. 4, Fig. 5, Fig. 6, the utility model additionally provide a kind of desk, including desktop 3, table leg 4 with And such as preceding supporting structure for furniture, the lid of desktop 3, which closes, to be connected on 2 top surface of the first brace 1 and the second brace, and first Brace 1 and the second brace 2 intersect when being cooperatively connected, and 1 length direction of the first brace and 2 length direction of the second brace constitute and connect Angle is connect, one end of table leg 4 is fixedly connected with joint angle side respectively, and the other end of table leg 4 is supported on ground.

Further, 4 length direction of table leg relative to 3 thickness direction central axis of desktop inclination angle be 40 ° extremely 50°.Using the technical solution, be conducive to the bearing area for expanding supporting structure, and structure when desk uses is more stable and can It leans on.

It is preferred that 3 top surface of desktop or bottom surface are round or square.Connected between table leg 4 and supporting structure using tapping screw It connects, self-drilling connection is used between desktop 3 and the first brace 1 or the second brace 2.Desk is assembled using the technical solution When, supporting structure is simple for assembly process, and when table leg is connect with supporting structure, tapping screw has along horizontal direction lateral arrangement Conducive to the bearing capacity for improving table leg, keep the structure of desk more stable and reliable.
