The same reference numbers in the figures indicate the same or similar structures.

The supporting structure of the table according to the embodiment of the present utility model will be described below with reference to FIGS. 1 to 8 . Specifically, the support structure 100 includes a plurality of support beams 110 , a plurality of support legs 130 and a plurality of multidirectional connectors 140 . In some embodiments, the number of support beams 110 , support legs 130 and multi-directional connectors 140 is the same. The supporting legs 130 are connected and fixed with the multidirectional connectors 140, and the adjacent supporting beams are connected by the connecting members 140 to form a closed supporting frame, so that each corner of the supporting frame is fixed with a supporting leg perpendicular to the plane where the supporting frame is located. 130.

In the embodiment shown in FIG. 1, there are four support beams 110, wherein only the opposite support beams 110 have the same length. Adjacent support beams 110 are connected by connecting pieces 140 , so that the support frame is a rectangle. Each support beam 110 has the same structure except for the length. Preferably, the support beam 110 is a support beam of metal material, especially a steel beam. The support beam 110 has a second cavity 111 . The cross-sectional shape of the second cavity 111 may be a parallelogram such as a rectangle, a rhombus, or a circle, and the present invention is not limited thereto. Both ends of the support beam 110 have through holes 112 .

Corresponding to the four support beams 110 , this embodiment provides four support legs 130 . The supporting legs 130 are preferably made of metal materials, especially aluminum alloy supporting legs. The supporting leg 130 has a first cavity 131 . The shape of the first cavity 131 is determined according to the shape of the supporting leg 130 . For example, the support leg 130 shown in FIG. 1 is a column with an "L" shape in cross section, and the cross section shape of the first cavity 131 is also "L" shape. The shapes of the supporting legs 130 and the first cavity 131 are only examples, and those skilled in the art can realize more variations, and are not limited thereto. The supporting leg 130 defines a first through hole 132 . Preferably, the first through hole 132 is disposed at the position of the supporting leg 130 as shown in FIG. 2 .

Corresponding to the four support beams 110 , this embodiment provides four multidirectional connectors 140 . The multi-directional connector 140 is preferably a metal connector, especially a die-cast connector manufactured by a die-casting process.

The structure of the multi-directional connector 140 in this embodiment is as shown in FIGS. A plurality of second support rods (eg, support beams 140). The multi-directional connector 140 includes at least one connecting portion 141 (one in the figure of this embodiment), at least one first connector 144 (one in the figure of this embodiment) and a plurality of second connectors 145 ( There are 2 in the illustration of this embodiment). A stopper 142 extending downward is formed on the first side of the connecting portion 141 . The first connecting head 144 is connected to the connecting portion 141 and has a locking groove 149 between the first side of the connecting portion 141 . When the first cavity 131 of the support leg 130 is sleeved on the first connector 144, the side wall of the support leg 130 is inserted into the slot 149 and abuts against the stopper 142, so that the single support leg 130 and the single connector 140 After initial assembly, it has a good positioning effect, is not easy to fall off and is convenient for later fine-tuning. Other parts can be assembled without manual support, and the overall assembly of the table can be completed quickly and conveniently. Since the first cavity 131 of the supporting leg is sleeved on the first connecting head 144, the shape of the first connecting head 144 is adapted to the first cavity 131. For example, in this embodiment, the transverse direction of the first cavity 141 The section is L-shaped, and correspondingly, the cross-section of the first connector is also L-shaped. Further, the cross section of the stopper 142 is arc-shaped, and the side of the first connecting head 144 opposite to the stopper 142 is also arc-shaped, so that the shape of the slot 149 is adapted to the sidewall of the support leg 130 .

In a preferred example, the stopper 142 also has a second through hole 143 opposite to the first through hole 132, for the fixing member to pass through the first through hole 132 and the second through hole 143 to connect the support leg 130 and the second through hole 143. Multidirectional connector 140 . Fixing parts can be screws, or other fixing parts.

The plurality of second connectors 145 are used to respectively connect the plurality of support beams 110 , specifically, the second connectors 145 are inserted into the second cavities 111 of the support beams 110 . In a preferred example, the outer surface of the second connector 145 is provided with a raised strip 146 extending along the insertion direction. The protruding strip 146 makes the second connecting head 145 easy to be inserted into the second cavity 111 in alignment. If the second connector 145 is very close to the size of the second cavity 111 of the support beam 110, there will be a large area of friction on each surface when inserted, and the resistance will be large and difficult to align when inserted; if the second connector 145 is larger than the support beam The second cavity 111 of 110 is much smaller, although it is easy to insert, but the connection is not tight. Therefore, the side of the connector is provided with a convex line along the insertion direction, which not only reduces the resistance during insertion, is easy to insert, but also facilitates alignment, so that the connector and the sides of the beam are tightly connected and the force is even.

Further, the second connector 145 has a through hole 147 adapted to the through hole 112 . When the through hole 147 is used for the second connector 145 to be inserted into the second cavity 111, the fixing member passes through the through hole 112 and the through hole 147 on the support beam 110 and is locked, further fixing the second connector 145 in the second cavity 111 inside. Fixing parts can be screws, or other fixing parts.

Specifically, two adjacent second connecting heads 145 are connected to the second side of the connecting portion 141 at a first angle A to each other. The first angle A is determined according to the shape of the support frame. Those skilled in the art can understand that the angles of the inner corners are determined according to the shape of the support frame. If the angles of the inner corners of the support frame are different, then the multi-directional connectors 140 with different first angles A can be used. In this embodiment, since the shape of the supporting frame is a rectangle, the angles of the inner corners are equal, therefore, the first angle A of the multi-directional connector 140 is also equal, and the first angle is 90 degrees.

In this embodiment, the number of the first connector 144 of the multi-directional connector 140 is one, the number of the second connector 145 is two, and the first connector 144 and the two second connectors 144 are in pairs. Perpendicular to each other. In some variations, the number of the first connecting head 144 of the multi-directional connector 140 is one, and the number of connecting parts 141 is two, which are respectively arranged on both sides of the first connecting head 144, and each connecting part 141 is connected to There are two second connectors 145 to connect the support beams in more directions.

In some modified embodiments, by using different multi-directional connectors and changing the number and length of the supporting beams, the supporting frame can be made into a square, rectangular, rhombus, trapezoidal or trapezoidal shape. By changing the multi-directional connector, the support legs may not be perpendicular to the plane where the support frame is located. The specific position of the stopper on the connecting portion, the specific shapes of the first and second connecting heads, etc. can be adjusted according to requirements. In addition, the multidirectional connector of the present invention is not limited to connecting the supporting legs and supporting beams of the table, and can also be used to connect other supporting rods to form three-dimensional structures such as furniture.

The installation of the support structure will be described below with reference to FIG. 2 , FIG. 7 and FIG. 8 .

The first through hole 132 on the supporting leg 130 is aligned with the second through hole 143 on the stopper 142 . The screws pass through the second through hole 143 and the first through hole 132 and are locked, so that each support leg 130 is connected with the multidirectional connector 140 .

Insert the second connector 145 of each multidirectional connector 140 into the second cavity 111 of the support beam 110 , and the through hole 112 of the second cavity 111 is aligned with the through hole 147 of the second connector 145 . The screw passes through the through hole 112 and the through hole 147 and is locked to further fix the second connector 145 in the second cavity 111 .

Adjacent support beams 110 are connected to each other to form a closed support frame. Each corner of the support frame is fixed with a support leg 130, and the support leg 130 is perpendicular to the plane where the support frame is located.

Further, the utility model also provides a table. The screws pass through a table board and respectively pass through the through hole 148 on the multidirectional connector 140 and the through hole 113 on the support beam 110 to be locked, thereby fixing the table board to the support structure 100 . The shape of the table top is preferably the same as that of the support frame, and the size of the table top is slightly larger than that of the support frame. For example, the table top is a rectangle slightly larger than the support frame. Those skilled in the art can realize different variations and are not limited thereto.
