[0004] The technical problem to be solved by the present invention is to provide a furniture frame connection structure with a small installation space, which is particularly suitable for connecting the end of a long and flat transverse frame member to a vertical frame member.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a furniture frame connection structure, including a vertical frame member and a transverse frame member arranged horizontally relative to the vertical frame member. The end of the transverse frame member is connected to the side of the vertical frame member through a connection component. The connection component includes a V-shaped groove block, a V-shaped connection block, and a connection fastener. One side of the V-shaped groove block has at least one laterally extending V-shaped groove. One side of the V-shaped connection block facing the V-shaped groove block has a laterally extending V-shaped structure for embedding in the V-shaped groove. When the V-shaped structure is embedded in the V-shaped groove, the V-shaped groove block and the V-shaped connection block form a V-shaped surface contact. The V-shaped groove block and the V-shaped connection block are respectively horizontally fixed in the side of the vertical frame member and the inner hole of the end of the transverse frame member. When the transverse frame member and the vertical frame member are connected, the V-shaped structure of the V-shaped connection block is embedded in the V-shaped groove of the V-shaped groove block, and the connection fastener fastens the V-shaped groove block and the V-shaped connection block together from the side, locking the V-shaped surface contact between the V-shaped groove block and the V-shaped connection block to realize the connection between the transverse frame member and the vertical frame member.

[0006] Further defined, the V-shaped groove block is horizontally fixed to the side of the vertical frame member, and the V-shaped connection block is horizontally fixed to the inner hole of the end of the transverse frame member; or, the V-shaped groove block is horizontally fixed to the inner hole of the end of the transverse frame member, and the V-shaped connection block is horizontally fixed to the side of the vertical frame member.

[0007] Even further defined, the connection component fixed to the side of the vertical frame member is horizontally fixed by an end fixing method, and the connection component fixed to the inner hole of the end of the transverse frame member is horizontally fixed by a side fixing method.

[0008] Further defined, the connecting fastener is a first screw. The sides of the V-shaped groove block and the V-shaped connecting block respectively have screw holes and through holes for mating with the first screw. The first screw is screwed into the screw hole through the through hole to fasten the V-shaped groove block and the V-shaped connecting block together.

[0009] To make the connection between the cross beam and the lifting column more stable, it is further defined that the number of the first screws is at least two, and the first screws are arranged horizontally with each other. The screw holes and through holes for mating with the first screw are respectively located at the middle positions of the V-shaped groove and the V-shaped structure.

[0010] To make the connection between the cross beam and the lifting column more stable, it is further defined that the end of the transverse frame member is also fastened to the bottom of the connection assembly fixed to the side of the vertical frame member through a second screw passing through the bottom of the transverse frame member.

[0011] It is further defined that the end of the transverse frame member has a decorative sleeve for decorating the connection gap between the end of the transverse frame member and the side of the vertical frame member.

[0012] It is further defined that the transverse frame member is a U-shaped pipe fitting, including an intermediate section and co-directional bending sections on both sides of the intermediate section. The ends of the two bending sections of the transverse frame member are respectively connected to the sides of the left and right vertical frame members through a connection assembly.

[0013] It is further defined that the V-shaped groove block is fixed to the side of the vertical frame member through its end, and the V-shaped connecting block is fixed to the outer hole wall of the inner hole at the end of the transverse frame member through its side. There is a screw through hole on the inner side surface of the bending section of the transverse frame member.

[0014] The screw through hole on the transverse frame member for mating with the first screw facilitates the installation of the first screw. At the same time, by setting the screw through hole on the inner side surface of the bending section of the transverse frame member, the user cannot see the screw through hole on the outside, making it more beautiful.

[0015] It is further defined that the transverse frame member is a straight pipe fitting.

[0016] A desk includes a tabletop and a support frame for supporting the tabletop. The support frame includes a lifting column and a cross beam. The lifting column and the cross beam are connected by the above-mentioned furniture frame connection structure. Among them, the lifting column is a vertical frame member, and the cross beam is a transverse frame member.

[0026] Example 1, as Figures 1 to 5As shown in the figure, a furniture frame connection structure includes a vertical frame member 1 and a horizontal frame member 2 arranged horizontally relative to the vertical frame member 1. The end of the horizontal frame member 2 is connected to the side of the vertical frame member 1 through a connection assembly. The connection assembly includes a V-groove block 3, a V-shaped connection block 4, and a connection fastener. The outer side of the V-groove block 3 has a laterally extending V-groove 3-1. The inner side of the V-shaped connection block 4 facing the V-groove block 3 has a laterally extending V-shaped structure 4-1 for embedding into the V-groove 3-1. When the V-shaped structure 4-1 is embedded into the V-groove 3-1, the V-groove block 3 and the V-shaped connection block 4 form a V-shaped surface contact. The V-groove block 3 is horizontally fixed to the side of the vertical frame member 1 through its end. The V-shaped connection block 4 is horizontally fixed to the outer hole wall of the inner hole at the end of the horizontal frame member 2 through its outer side. When the horizontal frame member 2 and the vertical frame member 1 are connected, the V-shaped structure 4-1 of the V-shaped connection block 4 is embedded into the V-groove 3-1 of the V-groove block 3, and the connection fastener fastens the V-groove block 3 and the V-shaped connection block 4 together from the side, locking the V-shaped surface contact between the V-groove block 3 and the V-shaped connection block 4, thus realizing the connection between the horizontal frame member 2 and the vertical frame member 1.

[0027] The connection fastener is a first screw 5. The sides of the V-groove block 3 and the V-shaped connection block 4 respectively have screw holes 6 and through holes 7 for mating with the first screw 5. The first screw 5 is screwed into the screw hole 6 through the through hole 7 to fasten the V-groove block 3 and the V-shaped connection block 4 together. Of course, in addition to screws, other common connection fasteners in the prior art are not excluded as connection fasteners.

[0028] The number of the first screws 5 is two. The first screws 5 are arranged horizontally with each other. The screw holes 6 and through holes 7 for mating with the first screws 5 are respectively located at the middle positions of the V-groove 3-1 and the V-shaped structure 4-1.

[0029] The end of the horizontal frame member 2 is also fastened to the bottom of the connection assembly fixed to the side of the vertical frame member 1, that is, the bottom of the V-groove block 3, through a second screw 8 passing through the bottom of the horizontal frame member 2. The bottom of the V-groove block 3 has a screw hole 6 for mating with the second screw 8.

[0030] The end of the horizontal frame member 2 has a decorative sleeve 9 for decorating the connection gap between the end of the horizontal frame member 2 and the side of the vertical frame member 1.

[0031] The horizontal frame member 2 is a U-shaped pipe fitting, including a middle section 2-1 and same-direction bending sections 2-2 on both sides of the middle section 2-1. The ends of the two bending sections 2-2 of the horizontal frame member 2 are respectively connected to the sides of the left and right vertical frame members 1 through connection assemblies.

[0032] The inner side of the bent section 2-2 of the horizontal frame member 2 is provided with screw through holes. The screw hole 6 matching the first screw 5 is located on the V-shaped connecting block 4, and the through hole 7 matching the first screw 5 is located on the V-shaped groove block 3. The first screw 5 enters the inner hole at the end of the horizontal frame member 2 through the screw through hole, fastening the V-shaped groove block 3 and the V-shaped connecting block 4 together.

[0033] In the drawings, the first screw 5 and the second screw 8 are specifically hexagon socket countersunk head screws, and the V-shaped groove block 3 and the V-shaped connecting block 4 are fixed by welding.

[0034] A desk, specifically an electric lifting desk, includes a tabletop and a support frame for supporting the tabletop. The support frame includes lifting columns and crossbeams. The lifting columns and the crossbeams are connected by the above-mentioned furniture frame connection structure. Among them, the lifting columns are vertical frame members 1, and the crossbeams are horizontal frame members 2.

[0035] The connection process of the crossbeam with the lifting columns on both sides is as follows: First, the V-shaped groove blocks 3 are inserted into the inner holes at the ends of the crossbeam by means of insertion at both ends of the crossbeam, and during the insertion process, the V-shaped structure 4-1 of the V-shaped connecting block 4 is embedded into the V-shaped groove 3-1 of the V-shaped groove block 3. When the decorative sleeves 9 inserted at both ends of the crossbeam reach the side surfaces of the lifting columns, the crossbeam is inserted in place. The shape of the front end surface of the decorative sleeve 9 conforms to the shape of the side surface of the lifting column, achieving the function of connecting the gap between the end of the decorative crossbeam and the side surface of the lifting column.

[0036] Then, the first screws 5 are respectively screwed in from the screw through holes on the inner side surfaces at both ends of the crossbeam. The first screws 5 enter the inner holes at the ends of the crossbeam through the screw through holes, fastening the V-shaped groove block 3 and the V-shaped connecting block 4 together. At this time, the crossbeam has been stably connected to the lifting columns.

[0037] The second screws 8 can be screwed at the bottoms of both ends of the crossbeam, applying an upward fastening force to the bottoms of both ends of the crossbeam to make the connection between the crossbeam and the lifting columns more stable.

[0038] Embodiment 2 is different from Embodiment 1 in that: the V-shaped groove block 3 is horizontally fixed in the inner hole at the end of the horizontal frame member 2, and the V-shaped connecting block 4 is horizontally fixed on the side surface of the vertical frame member 1.

[0039] Embodiment 3 is different from Embodiment 1 in that: the side surfaces of the V-shaped groove block 3 and the V-shaped connecting block 4 have more than one V-shaped groove 3-1 and V-shaped structure 4-1 extending horizontally, such as having two V-shaped grooves 3-1 and two V-shaped structures 4-1 respectively.

[0040] Embodiment 4 is different from Embodiment 1 in that: the V-groove block 3 not only has a V-groove 3-1 but also a V-shaped structure 4-1, and correspondingly, the V-shaped connection block 4 also has a matching V-groove 3-1 and V-shaped structure 4-1, so that a V-shaped surface contact is formed between the V-groove block 3 and the V-shaped connection block 4.

[0041] Embodiment 5 is different from Embodiment 1 in that: the transverse frame member 2 is a straight pipe, and the end of the transverse frame member 2 is connected to the side surface of the vertical frame member 1 through a connection assembly. When assembling the support frame of the office desk with the furniture frame connection structure of this Embodiment 5, the cross beam and the lifting column can be connected first, and then the desktop frame 10 on the upper layer of the support frame can be assembled. The lifting column is the vertical frame member 1, and the cross beam is the transverse frame member 2.

[0042] Figure 6 Shown is the support frame in one of the row forms of this embodiment. The support frame is used for the front and rear two office desks placed in a row. The transverse frame member 2 of the support frame, that is, the cross beam, is a straight pipe, and the two ends of the cross beam are respectively connected to the side surfaces of the front and rear two vertical frame members 1, that is, the lifting columns, through the connection assembly of the present invention.
