In some embodiments, as shown in fig. 4 to 7, one end of the transverse cantilever beam 5, which is close to the mounting seat 201, is connected with a connecting plate 503, at least one mounting hole 504 extending along the vertical direction is arranged on the connecting plate 503, a connecting screw 505 is matched in each mounting hole 504 in a clearance way, and a connecting hole 202 correspondingly connected with the connecting screw 505 is arranged on the mounting seat 201; the connection plate 503, the mounting hole 504, and the connection screw 505 form the connection portion. In this embodiment, the connecting hole 202 on the mounting seat 201 is a threaded hole, when the transverse cantilever beam 5 is mounted, the free end of the connecting screw 505 in the mounting hole 504 is connected with the connecting hole 202, and the mounting hole 504 extends in the vertical direction on the connecting plate 503, so that the height of the transverse cantilever beam 5 can be adjusted, and after the height of the transverse cantilever beam 5 is adjusted, the connecting screw 505 can be locked, so that the height of the transverse cantilever beam 5 is fixed.

As described above, the second transmission rod is connected between the two second electric lifting columns 3, so when the second transmission rod is assembled, both ends of the second transmission rod need to be in transmission connection with the linear driving mechanisms in the two second electric lifting columns 3, and when both ends of the second transmission rod are respectively in transmission installation with the linear driving mechanisms in the two second electric lifting columns, the heights of the two second electric lifting columns 3 in the initial state (folded or contracted to the shortest length) are often different due to the assembly error of the linear driving mechanisms or the transmission angle of the transmission rod assembly; further, when the mounting base 201 is welded to the first movable stand 200, the difference in welding position and the like may cause the left and right heights of the two second electric lifting stands 3 to be different; therefore, according to the actual installation condition, the height of the transverse cantilever beam 5 on the installation seat 201 can be adjusted, and when the adjustment is performed, the height of the transverse cantilever beam 5 can be adjusted by unscrewing the connecting screw 505, so that the height adjustment is simple and convenient.

In other embodiments, a mounting hole 504 extending along the vertical height direction may be provided on the mounting seat 201, a connection screw 505 is in clearance fit with the mounting hole 504, and a connection hole 202 or a threaded hole is provided on the connection plate 503 of the transverse cantilever beam 5, that is, the connection hole 202 and the mounting hole 504 in the above embodiments are interchanged to the connection plate 503 and the mounting seat 201. Also, in other embodiments, the number and shape of the mounting holes 504 can be set according to actual requirements.

In some embodiments, referring to fig. 4, 5 and 7, the top of the transverse cantilever beam 5 is screwed with a vertically disposed limit screw 503, and the free end of the limit screw 503 abuts against one of the connection screws 505 for positioning the connection screw 505 in the mounting hole 504.

When the free end of the connection screw 505 is connected with the connection hole 202 on the mounting seat 201, the limit screw 503 is rotated, so that the free end of the limit screw 503 is propped against the top of one of the connection screws 505, and the connection screw 505 can be limited to slide in the mounting hole 504, so that the situation that the transverse cantilever beam 5 slides downwards or loosens accidentally due to the overload of the second table plate 100 is avoided, and the supporting performance and the bearing capacity of the transverse cantilever beam 5 are greatly improved.

In order to enable a user to screw or unscrew the connecting screw 505 conveniently, the height of the transverse cantilever beams 5 is adjusted conveniently, a first avoiding hole 500 corresponding to the connecting screw 505 is formed in each transverse cantilever beam 5, and in order to keep the surface of the transverse cantilever beam 5 smooth, a detachable cover plate can be connected to the first avoiding hole 500.

In some embodiments, in order to enable the distance between the second table 100 and the first table 1 to be adjustable, and avoid unequal intervals between the second table 100 and the first table 1, as shown in fig. 5 and 6, a plurality of adjusting holes 507 extending along the length direction of the transverse cantilever beam 5 are provided at the top of the transverse cantilever beam 5, the bottom of the second electric lifting upright 3 is connected with the adjusting holes 507 through fasteners 302, and the position of the second electric lifting upright 3 can be adjusted along the length direction of the adjusting holes 507 so as to adjust the gap between the second table 100 and the first table 1. Likewise, in order to facilitate the user's loosening or tightening of the fastener 302, a second relief hole 501 corresponding to the fastener 302 is provided in each of the lateral outriggers 5.

In some embodiments, as shown in fig. 2 and fig. 3, a vertical baffle plate 101 extending downwards is fixed on one side of the second table plate 100 close to the first table plate 1, and an anti-friction gap is reserved between the vertical baffle plate 101 and the first table plate 1; the height of the vertical baffle 101 is configured to: the bottom end of the vertical baffle 101 is still below the top plane of the first table 1 or is flush with the top plane of the first table 1 when the second table 100 is in a position higher than the maximum height of the first table 1. When the second table 100 is higher than the first table 1, the vertical baffle 101 can prevent the articles on the first table 1 from falling from the rear side of the first table 1, and can also prevent hands from being carelessly stretched into the lower part of the second table 100 to be injured when the second table 100 descends relative to the first table 1. Also when the second table 100 is lifted to the highest position relative to the first table 1, the articles on the first table 1 can still be guaranteed not to fall from the rear side of the first table 1, the second table 100 can be prevented from falling from the highest position to the original, hands can not be injured by the vertical baffle 101 and the second table 100, and the safety is high.

In this embodiment, as mentioned above, the lifting column is retracted to the lowest position of the structure and then rebounds upwards by a certain distance or height, so that there is a certain height difference between the lowest position of the lifting column structure and the lowest position of the actual lifting column, that is, the lowest position of the lifting column is slightly higher than the lowest position of the lifting column structure, so that the second table 100 is kept level with the first table 1 when the lifting column is lowered to the lowest position in order to eliminate the rebounds height of the lifting column. Therefore, after the electric lifting table is assembled, the height of the top plane of the second table plate 100 is lower than that of the top plane of the first table plate 1, and the height difference between the first table plate 1 and the second table plate 100 is equal to the rebound height of the second electric lifting upright 3.

In particular, when the electric lifting table is used, the electric lifting table can be inverted, so that the first table plate 1 is downwards contacted with the ground, a plurality of support cushion blocks 6 are arranged on the periphery of the second table plate 100, each support cushion block 6 comprises two vertical plates 600 which are mutually perpendicular and are cross-shaped, and a horizontal plate 601 which is arranged between the two vertical plates 600, and the horizontal plate 601 and the two vertical plates 600 are of an integrated structure; the bottom of the horizontal plate 601 of the supporting cushion block 6 is provided with a first plane 602 which is attached to the top plane of the second table plate 100, the top of the horizontal plate 601 is provided with a second plane 603, and the distance between the first plane 602 and the second plane 603 is equal to the rebound height of the second electric lifting upright 3; therefore, the first plane 602 of the supporting cushion block 6 is always attached to the top plane of the second table 100, and the second plane 603 is flush with the top plane of the first table 1 or attached to the ground, and after the electric lifting table is assembled, all supporting cushion blocks 6 are removed. After the electric lifting table is assembled, the two first electric lifting upright posts 2 and the second electric lifting upright posts 3 are in a reset state or the lowest reset state of the structure, the height of the second table plate 100 is lower than that of the first table plate 1, and the height difference between the second table plate 100 and the first table plate 1 is equal to the rebound height of the second electric lifting upright posts 3, so that when the electric lifting table is used, for example, the second table plate 100 is independently started to rise for a certain height and then returns to the lowest position, the second table plate 100 and the first table plate 1 can be kept level due to the existence of the rebound height of the second electric lifting upright posts 3; in other words, when the electric lifting table is assembled, the rebound height of the second electric lifting upright 3 is reserved in advance, when both the two first electric lifting uprights 2 and the two second electric lifting uprights 3 are in the reset state or the lowest reset state of the structure, the height of the second table plate 100 is lower than that of the first table plate 1, and the height difference of the two is exactly equal to the rebound height of the second electric lifting upright 3, so that the second table plate 100 can be kept flush with the first table plate 1 in the actual use process, particularly when the second table plate 100 alone ascends and descends. The electric lift table thus eliminates or reduces the drawback of the second table 100 not being flush with the first table 1 due to the rebound height of the second electric lift column 3.

The supporting cushion block 6 can keep the side walls of the second table plate 100 and the first table plate 1 to be level, namely, the side walls of the second table plate 100 and the first table plate 1 are simultaneously attached to the side walls of the vertical plate 600; the gap between the second table plate 100 and the first table plate 1 may be kept equal, that is, another vertical plate 600 is inserted into the gap between the second table plate 100 and the first table plate 1, and two sides of the vertical plate 600 are respectively attached to corresponding side walls of the second table plate 100 and the first table plate 1.
