Description

Technical Field

[0001] The utility model relates to the technical field of furniture, and in particular to a lifting table. Background Art

[0002] As people pay more and more attention to their health, more and more users are seeing lift tables that can freely adjust the height. The lift table can adjust the height of the table according to the user's sitting or standing height. On the one hand, it helps to maintain the user's healthy body posture, and on the other hand, it can also relieve physical fatigue caused by long-term work and study, and reduce muscle strain.

[0003] In the prior art, a lifting table uses telescopic sleeves and table legs fixed with pins, which is inconvenient to adjust. The height can only be adjusted according to several plug-in positions preset on the telescopic sleeves of the table legs, and arbitrary height adjustment cannot be achieved.

[0004] Another type of lifting table can use an electric lifting column, but the lifting of one table leg is controlled individually, and the other table legs are passively adjusted, which often causes uneven movement and jamming. In addition, the driving components of the lifting column use synchronous belts and synchronous gears, which have a complex structure and high cost. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting table to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model is implemented by the following technical means:

[0007] A lifting table includes a tabletop, a table frame, lifting table legs, and table feet.

[0008] The table legs are provided in two groups, including a support base, rolling wheels are movably mounted on both sides of one end of the support base, and supporting feet are respectively mounted on both ends of the bottom of the support base;

[0009] The lifting table legs are respectively installed on the table feet, including an outer guide sleeve fixedly connected to the table feet, an inner guide sleeve movably connected inside the outer guide sleeve, a lifting mechanism is installed inside the inner guide sleeve, the lifting mechanism includes a limit sleeve rod, a limit sleeve is installed at the lower part of the inner wall of the limit sleeve rod, the limit sleeve is movably equipped with a screw rod extending upward along the limit sleeve rod, and the upper part of the screw rod is cooperatively connected with an active driving mechanism arranged on the table frame;

[0010] The table frame is mounted on the top of the two lifting table legs and is composed of two longitudinal rectangular sleeves and two transverse rectangular sleeves. The two longitudinal rectangular sleeves are respectively equipped with an active driving mechanism and a passive driving mechanism that cooperate with the screw rods in the two lifting table legs. The active driving mechanism is connected to the passive driving mechanism through a transmission guide rod, and the active driving mechanism is connected to the driving guide rod installed in the longitudinal rectangular guide tube.

[0011] The desktop is installed above the table frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model can link the active driving mechanism and the passive driving mechanism by rotating the driving guide rod. The active driving mechanism and the passive driving mechanism cooperate with the corresponding lifting mechanism to adjust the height arbitrarily. The structure is simple and the installation and maintenance are convenient. BRIEF DESCRIPTION OF THE DRAWINGS
