One end of the side section beam 12 is provided with a linking portion 123, and each of the side section beams 12 is coupled to each of the joining portion 113 of the middle section beam 11 through the linking portion 123.

[0023] The beam structure 10 further includes a pair of guide grooves 13 which are defined in middle side edges of the middle section beam 11 and each side section beam 12 and are arranged corresponding to each other.

[0024] The beam structure 10 further includes a casing pipe 14. The casing pipe 14 encloses the middle section beam 11 and each of the side section beams 12.

[0025] The beam structure 10 further includes a pair of end covers 15. Each of the end covers 15 covers on one end of each side section beams 12 away from the middle section beam 11 and is connected to the casing pipe 14.

[0026] The electrical device 40 mainly includes a controller 41 and a conductive circuit 45. The controller 41 is installed inside the middle section beam 11 and is mainly used for rectification, filtering and voltage reduction, and other related work. The conductive circuit 45 mainly includes a first guide module 46, a second guide module 47, and a third guide module 48. The first guide module 46 is installed in the left one of the side section beams 12, the second guide module 47 is installed in the middle section beam 11, and the third guide module 48 is installed in the right one of the side section beam 12.

[0027] Referring to FIGS. 4 to 7, the support bars 20 mainly includes a base 21 made of aluminum alloy by die casting or the like, and generally has a T shape; however, the present application is not limited to this particular shape. The support bar 20 further includes a first arm 211 extended from one side of the base 21 and has a height difference with the base 21, a second arm 212 extended in an opposite direction to the first arm 11 and has a height difference with the base 21, and a third arm 213 extended away from a connection direction of the first arm 211 and the second arm 212 and has a height difference with the base 21. An accommodating space A is formed among the base 21, the first arm 211, the second arm 212, and the third arm 213. The beam structure 10 is operatively moved in or out of the accommodating space A. End portions of the first arm 211, the second arm 212, and third arm 213 away from the base 21 are on a same plane.

[0028] The conductive circuit 45 further includes a fourth guide module 49, and the fourth guide module 49 is installed in the base 21. The base 21 is provided with a wire-receiving groove 214, and the fourth guide module 49 is embedded in the wire-receiving groove 214 and fixed by a press plate 22. In addition, a through hole 2111 and a through hole 2121 are defined respectively in the end portion of the first arm 211 and the end portion of the second arm 212.

[0029] The third arm 213 includes a supporting element 2131 and a fixed plate 2132 extended horizontally from an end of the supporting element 2131. In the present embodiment, the supporting element 2131 has a C shape, but the present application is not limited to this particular shape. A pair of protruding strips 2133 protrude from an inner surface of the supporting element 2131, and each protruding strip 2133 is engaged with each guide groove 13 of the beam structure 10. A through hole 2134 is defined in each fixed plate 2132.

[0030] The upright structures 30 are connected to the support bars 20 respectively, and each upright structure 30 includes an electric motor 31 and a plurality of extendable tubes 32. The electric motor 31 is installed inside the extendable tubes 32 and is used to drive each extendable tube 32 to extend or retract. The electric motor 31 is electrically connected to the aforementioned fourth guide module 49 through an electrical contact 33, and the electrical contact 33 is fixed on an upper end surface of the extendable tube 32, thereby achieving electrical connection when the upright structure 30 and the support bar 20 are assembled.

[0031] Referring to FIGS. 8 and 9, during use, the side section beams 12 are engaged with the respective corresponding protruding strips 2133 by using the guide grooves 13. Users can move the support bar 20 and the upright structure 30 together according to requirements, thereby adjusting relative positional relationship between the support bar 20, the upright structure 30, and the beam structure 10. In the foregoing process, a portion of the beam structure 10 that passes through the third arm 213 is operably moved in or out of the accommodating space A while the conductive circuit 45 is kept in an ON state.

[0032] Referring to FIG. 10, the electric table stand for simple assembly and adjustment according to the present invention can be combined with a table top board 8, and the table top board 8 is set on a support plane constructed by the first arm 211, the second arm 212, and the third arm 213 of each support bar 20. Moreover, the table top board 8 is fixed by fastening screws or other fastening elements in the through holes 2111, 2121, 2134.

[0033] As shown in FIG. 11, in addition to the above-mentioned embodiment, the beam structure 10 of the present invention can be provided with an opening 141A inside the casing pipe 14A. The first guide module 46 and the third guide module 48 are disposed on two sides of the casing pipe 14A. The controller 41 and the second guide module 47 are installed inside the middle section beam 11. The middle section beam 11 is coupled to the casing pipe 14A corresponding to the opening 141A. This way, the middle section beam 11 alone can be removed during maintenance, which facilitates the ease and convenience in assembly and maintenance.

[0034] Referring to FIG. 12, in the present embodiment, the first guide module 46 and the third guide module 48 are replaced with a guide wire 450, and two ends of the guide wire 450 are electrically connected to one end of the guide module 47 and one end of the fourth guide module 49, thereby greatly saving costs of materials.
