Abstract

The disclosure is a beam structure for a leg stand of an electric table, which includes a first frame and a second frame. The first frame includes an inner bottom plate, an inner side plate and an inner embedding plate. The inner embedding plate is formed on outside of the inner side plate. The inner embedding plate includes an exposed section. The second frame is movably connected with the first frame. The second frame includes an outer bottom plate, an outer side plate and an outer connecting plate. The inner bottom plate is formed above the outer bottom plate. The inner side plate is formed on inside of the outer side plate. The inner embedding plate is correspondingly embedded in the outer connecting plate. The exposed section is exposed from the outer connecting plate.

First claim

What is claimed is:

1. A beam structure for a leg stand of an electric table, the beam structure comprising:
a first frame, comprising an inner bottom plate, two inner side plates upward bent and extended from two sides of the inner bottom plate, and two inner embedding plates bent and extended from the inner side plates respectively, each inner embedding plate disposed on outside of each inner side plate, and each inner embedding plate comprising an exposed section; and
a second frame, movably connected with the first frame, comprising an outer bottom plate, two outer side plates upward bent and extended from two sides of the outer bottom plate, and two outer connecting plates outward bent and extended from the outer side plates respectively, the inner bottom plate disposed above the outer bottom plate, each inner side plate disposed on inside of each outer side plate, and each inner embedding plate correspondingly embedded in each outer connecting plate, wherein the exposed section is exposed from the outer connecting plate,
wherein the exposed section comprises a platform with a first upper surface, each inner embedding plate comprises a second upper surface, and the first upper surface is located to be higher than the second upper surface.

2. The beam structure of claim 1 , wherein the inner bottom plate comprises a lower exposed section, and the lower exposed section is exposed from the outer bottom plate.

3. The beam structure of claim 2 , wherein the lower exposed section comprises a lower platform with a first lower surface, the outer bottom plate comprises a second lower surface, and the second lower surface and the first lower surface are substantially on a same plane.

4. The beam structure of claim 1 , wherein the beam structure is composed of the first frame and the second frame.

5. The beam structure of claim 1 , wherein each outer connecting plate comprises a lower plate and an upper plate extended from and disposed above the lower plate, a slot is defined between the upper plate and the lower plate, and each inner embedding plate is correspondingly inserted in the slot.

6. The beam structure of claim 5 , wherein the exposed section comprises a platform with a first upper surface, each upper plate comprises a third upper surface, and the first upper surface and the third upper surface are substantially on a same plane.

7. The beam structure of claim 1 , wherein each outer connecting plate comprises multiple locking holes defined at intervals, each inner embedding plate comprises a positioning hole, and the positioning hole is selectively aligned with one of the locking holes to be positioned.

8. A beam structure for a leg stand of an electric table, the beam structure comprising:
a first frame, comprising an inner bottom plate, two inner side plates upward bent and extended from two sides of the inner bottom plate, and two inner embedding plates bent and extended from the inner side plates respectively, each inner embedding plate disposed on outside of each inner side plate, and each inner embedding plate comprising an exposed section; and
a second frame, movably connected with the first frame, comprising an outer bottom plate, two outer side plates upward bent and extended from two sides of the outer bottom plate, and two outer connecting plates outward bent and extended from the outer side plates respectively, the inner bottom plate disposed above the outer bottom plate, each inner side plate disposed on inside of each outer side plate, and each inner embedding plate correspondingly embedded in each outer connecting plate, wherein the exposed section is exposed from the outer connecting plate,
wherein the exposed section comprises a platform with a first upper surface, each outer connecting plate comprises a third upper surface, and the first upper surface and the third upper surface are substantially on a same plane.
