[0029] Example:

[0030] A lifting column, such as Figures 1 to 5 As shown, it includes a lifting column 1 and a support assembly installed at the lower part of the lifting column 1, the support assembly includes a base 2 and a support member 3 installed inside the base 2, the lower part of the lifting column 1 extends into the base 2 and is fixed on the support member 3, the support member 3 includes a mounting plate 31 arranged at the bottom of the lifting column 1 and a first reinforcing rib 32 fixed on the outer wall of the lifting column 1, the mounting plate 31 is fixed in the base 2 to prevent the mounting plate 31 from moving in the horizontal direction or the vertical direction, the side surface of the first reinforcing rib 32 is fixed on the outer wall of the lifting column 1, and the bottom surface of the first reinforcing rib 32 is fixed on the top surface of the mounting plate 31, so that the first reinforcing rib 32 supports and limits the outer wall of the lifting column 1 to prevent the lifting column 1 from shaking in the horizontal direction.

[0031] The present invention extends the lower part of the lifting column 1 into the base 2 of the support assembly and connects it with the support member 3. The support member 3 is fixed in the base 2 through the mounting plate 31 to prevent the mounting plate 31 and the lifting column 1 fixed on the mounting plate 31 from moving in the horizontal or vertical direction. The connection between the mounting plate 31 and the base 2 can also provide pre-tightening force for both sides of the lifting column to achieve the purpose of reducing the shaking of the lifting column 1. The support member 3 forms support and limit for the outer wall of the lifting column 1 through the first reinforcing rib 32, increases the overlap between the lower part of the lifting column 1 and the support assembly, has a better support effect on the lifting column 1, prevents the lifting column 1 from shaking in the horizontal direction, makes the lifting column more stable for the supported structure, and provides a good user experience.

[0032] The first reinforcing rib 32 includes at least two vertically arranged support plates, which are arranged around the circumference of the lifting column 1 to limit the circumferential position of the lifting column 1. The spacing between any two adjacent support plates is equal to ensure that the forces on the circumference of the lifting column 1 are the same and more stable. In this embodiment, preferably, two support plates are provided, and the two support plates are symmetrically arranged on both sides of the lifting column 1.

[0033] The base 2 in this embodiment includes a bottom plate 21 and an upper shell 22 mounted on the bottom plate 21. The upper shell 22 covers the bottom plate 21 to form a receiving cavity 23 for receiving the support member 3. The support plate is mounted on the bottom plate 21. The detachable upper shell 22 and bottom plate 21 facilitate the installation, disassembly and maintenance between the lifting column 1 and the base 2. The upper shell 22 is provided with a through hole 221 for the lifting column 1 to pass through. The base 2 also includes a dust cover 24 mounted on the upper part of the upper shell 22. The dust cover 24 covers the through hole 221 and is locked with the support plate and the bottom plate 21 by a locking member 26. The dust cover 24 and the bottom plate 21 clamp the upper shell 22 together to press the upper shell 22 on the bottom plate 21 to achieve the fixation between the upper shell 22 and the bottom plate 21. At the same time, the dust cover 24 can close the through hole 221 to prevent water and dust dripping from a high place from entering the base 2 through the through hole 221, thereby ensuring the dryness and cleanliness of the base 2.

[0034] The dust cover 24 in this embodiment includes a first dust cover and a second dust cover respectively located on both sides of the lifting column 1. The first dust cover and the second dust cover are against the outer wall of the lifting column 1 to limit the lifting column 1, strengthen the support of the base 2 for the lifting column 1 in the horizontal direction, and prevent the lifting column 1 from shaking. A mounting column 241 is provided on the bottom surface of the dust cover 24, and the locking member 26 passes through the bottom plate 21 and the mounting plate 31 in sequence, and penetrates into the mounting column 241 and locks with the mounting column 241 to achieve the locking and fixing of the three, with a simple structure and convenient installation. A plurality of second reinforcing ribs 242 are also provided on the bottom surface of the dust cover 24 to prevent the mounting column 241 from shaking. The plurality of second reinforcing ribs 242 are crisscrossed on the bottom surface of the dust cover 24, which improves the connection strength between the mounting column 241 and the dust cover 24 while enhancing the strength of the dust cover 24. The second reinforcing rib 242 at the lower part of the dust cover 24 extends into the accommodating cavity 23 and abuts against the top of the first reinforcing rib 32, so that the dust cover 24 can also limit the lifting column 1 by pressing the first reinforcing rib 32, making the lifting column 1 more stable.

[0035] The base 2 in this embodiment further includes an anti-wear support foot 25 mounted on the bottom plate 21 to prevent the base 2 from causing wear on the ground. The anti-wear support foot 25 can be a support column with a rubber bottom, or a roller or other structure. Preferably, the bottom plate 21 is recessed toward the accommodating cavity 23 to form an installation groove 211 for accommodating the anti-wear support foot 25, so that the upper part of the anti-wear support foot 25 is hidden in the installation groove 211, which is more beautiful.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
