[0017] The utility model will be further described in detail in combination with the embodiments given in the drawings.

[0018] As shown in the drawings, Figs. 1 to 4 The table beam comprises a beam body 1, and a stepped portion 2 is recessed downward from the upper end surface of the beam body 1 on one side of the beam body 1. An upwardly open clamping groove 3 is arranged on the beam body 1, and the clamping groove 3 allows an extended table plate 4 to be inserted into the clamping groove 3 from one end of the clamping groove 3 and clamped therewith. A support plate 5 extends outward from the upper end surface of the beam body 1 on the other side of the beam body 1, and the support plate 5 can provide good support for the extended table plate 4 when the extended table plate 4 is added, so that the table is more stable and reliable in use.

[0019] As described above, the clamping groove 3 comprises an arc-shaped groove wall 31 at the bottom and a first side wall 32 and a second side wall 33 on the two sides of the arc-shaped groove wall 31 respectively, and the first side wall 32, the arc-shaped groove wall 31 and the second side wall 33 enclose the clamping groove 3.

[0020] As described above, the cross section of the arc-shaped groove wall 31 is in the shape of a superior arc, the cross section of the first side wall 32 is in the shape of an inferior arc, the arc-shaped notch is arranged towards the end provided with the support plate 5, and the second side wall 33 is arranged obliquely. Such a structural design makes the connection of the extended table plate 4 and the clamping groove 3 more stable and reliable.

[0021] As described above, the inside of the beam body 1 is hollow and forms the first cavity 6. Such a structure design makes the weight of the table beam lighter.

[0022] As described above, the bottom end of the beam body 1 extends downward to form the table leg connecting part 7, and the inside of the table leg connecting part 7 is hollow and forms the second cavity 8. Such a structure design makes the weight of the table beam lighter again.

[0023] As described above, the expansion table plate 4 is also included, and one side of the expansion table plate 4 is provided with a downwardly bent clamping part 41, and the bottom end of the clamping part 41 is provided with a convex part 42, and the cross section of the convex part 42 is an arc shape. When installing the expansion table plate 4, the clamping part 41 is inserted into the clamping groove 3 from one end of the beam body 1 and clamped, and vice versa, the expansion table plate 4 assembled on the clamping groove 3 can be disassembled from the beam body 1. The other side of the expansion table plate 4 is provided with a downwardly extending extension edge 43, which can play a protective role. Specifically, when the expansion table plate 4 is assembled with the beam body 1, the bottom of the expansion table plate 4 abuts against the upper end surface of the support plate 5, and the support plate 5 can provide better support for the expansion table plate 4, so that the expansion table plate 4 is more stable.

[0024] As described above, the support plate 5 is provided with a hollow hole 51 along the length direction of the support plate 5, which not only reduces the weight of the table beam, but also the shape of the hole can be designed according to the actual demand to make the table beam more beautiful.

[0025] The above is only a preferred embodiment of the present application, which cannot limit the scope of the present application, that is, any simple equivalent changes and modifications made according to the patent application scope and the utility model description of the present application are still within the scope of the present application.
