Description

Technical Field

[0001] This utility model relates to the field of electric height-adjustable desk technology, and specifically to a lifting column assembly for an electric height-adjustable desk. Background Technology

[0002] Electric height-adjustable desks are popular among office workers due to their convenient height adjustment, making them suitable for people of different heights. They are becoming increasingly common. Current electric height-adjustable desks generally use two lifting columns for support. However, as desktops become larger, two lifting columns are no longer sufficient for effective support. Therefore, electric height-adjustable desks with four lifting columns have appeared on the market. However, existing desks with four lifting columns, whether square or round, lack edging and appear small and unattractive. Making them large enough for decorative purposes would be too bulky, requiring improvement. Utility Model Content

Detailed Implementation

[0025] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] Example: Refer to Figures 1 to 6The present invention discloses a lifting column assembly for an electric lifting table. The lifting assembly 1 passes through a decorative cylinder 3, which is an integrally formed cylindrical body. The connecting block 2 on the outside of the lifting assembly 1 is connected to the decorative cylinder 3, which serves to protect the lifting assembly 1 and for decoration. The upper and lower ends of the decorative cylinder 3 are respectively connected to a first sealing edge 4 and a second sealing edge 5 to prevent garbage from falling into the decorative cylinder 3 and to serve a decorative purpose. Because of the decorative cylinder 3, the lifting assembly 1 does not need to be made larger for aesthetic purposes. Since the decorative cylinder 3 is a cylindrical body, it is lighter in weight, which makes the weight of the entire lifting column relatively lighter, making it convenient for transportation and installation.

[0027] Specifically, the connecting block 2 is welded to the outer wall of the lifting assembly 1, so that the connecting block 2 is more stably connected to the lifting assembly 1. The connecting block 2 is provided with several threaded holes 21. The decorative cylinder 3 is connected to the first threaded hole 21 with screws, and then connected to the lifting assembly 1. The threaded connection is stable and easy to install.

[0028] Specifically, the lifting assembly 1 also includes a connecting protrusion 6, and the decorative tube 3 is provided with a U-shaped groove that mates with the connecting protrusion 6. The decorative tube 3 fits tightly with the lifting assembly 1, reducing gaps and making it more aesthetically pleasing.

[0029] Specifically, the decorative tube 3 has several mounting holes 31 at both ends. The first sealing edge 4 is connected to the mounting hole 31 at the upper end of the decorative tube 3, and the second sealing edge 5 is connected to the mounting hole 31 at the lower end of the decorative tube 3 with screws. The pre-set mounting holes 31 make it easier to connect the screws and make the installation faster.

[0030] Specifically, the decorative tube 3 has through grooves 32 at each of its four corners, with openings at both ends of the through grooves 32 forming mounting holes 31, which improves the elasticity of the mounting holes 31 and facilitates quick connection of screws.

[0031] Specifically, the first edge seal 4 is provided with a protruding post 41 that mates with the mounting hole 31. The protruding post 41 is detachably connected to the mounting hole 31, making installation and removal more convenient.

[0032] Specifically, the second sealing edge 5 is provided with several flanges 51. The flanges 51 are detachably connected to the connection port 33 formed between the through grooves 32. The flanges 51 are detachably connected to the connection port 33, which increases the connection between the second sealing edge 5 and the decorative tube 3 and makes disassembly and assembly convenient.

[0033] Specifically, the second edge seal 5 includes an outer ring screw hole 52 and an inner ring screw hole 53. The screw is connected to the mounting hole 31 through the outer ring screw hole 52. The screw, together with the inner ring screw hole 53, connects the second edge seal 5 to the lifting assembly 1, thereby enhancing the stability of the connection between the second edge seal 5, the lifting assembly 1, and the decorative cylinder 3.

[0034] Specifically, the four corners of the cross-section of the decorative tube 3 are rounded, and the four sides of the cross-section of the decorative tube 3 are outwardly convex arc surfaces, which makes the appearance more beautiful and prevents people from being injured by the edges and corners during use.
