The liftable table leg assembly also includes a rotating shaft arranged under the desktop support and driven by a motor to rotate. The two ends of the rotating shaft are respectively provided with first bevel gears corresponding to the two table legs, and the inner tube is provided with A screw that can rotate up and down, the top of the outer tube is provided with a bearing seat, the screw passes through the bearing seat and is rotatably arranged on the outer tube, and the top of the screw corresponds to the first bevel gear. There is a second bevel gear meshing with the first bevel gear.

A nut threadedly engaged with the screw rod is arranged in the inner tube.

A guide gasket is provided on the outer wall of the lower end of the inner tube corresponding to the outer tube.

The rotating shaft is a hexagonal rotating shaft.

Both the inner tube and the outer tube are square tubes.

The motor is fixed on the lower surface of the desktop support.

The beneficial effects of the utility model are as follows: the utility model simultaneously drives two table legs to rise and fall simultaneously through a motor, has a simple and reasonable structure, ingenious design, stable working performance, low product failure rate, and is easy to maintain, that is, the production cost is reduced, It also reduces the cost of use.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

detailed description

Embodiment: As shown in Figures 1 to 3, a liftable dining table of the present invention includes a base 1 on which a liftable table leg assembly 2 is arranged, and the top end of the liftable table leg assembly 2 A desktop support 3 is provided, and a desktop is fixed on the desktop support 3. The liftable table leg assembly 2 includes at least two table legs, and the table legs include an inner tube 21 and are sleeved on the inner tube 21 and can be relatively The inner tube 21 moves up and down the outer tube 22 , the outer tube 22 is connected with the desktop support 3 , and the inner tube 21 is fixedly connected with the base 1 .

The liftable table leg assembly 2 also includes a rotating shaft 24 arranged below the desktop support 3 and driven by a motor 23 to rotate. The two ends of the rotating shaft 24 are respectively provided with first bevel gears 25 corresponding to the two table legs. The inner tube 21 is provided with a screw rod 26 that can rotate up and down, and the top of the outer tube 22 is provided with a bearing seat 27, and the screw rod 26 is rotatably arranged on the outer tube 22 through the bearing seat 27. The top end of the screw rod 26 corresponds to the first bevel gear 25 and is provided with a second bevel gear 28 meshing with the first bevel gear 25 .

A nut threadedly engaged with the screw rod 26 is provided in the inner tube 21 .

Described two screw rods 26, wherein the tooth shape on one screw rod 26 is positive tooth, the tooth shape that is established on the nut that cooperates with this screw rod 26 is reverse tooth; The tooth shape on the other root screw rod 26 is reverse tooth, The tooth shape provided on the nut matched with the screw rod 26 is reverse tooth, so that the two screw rods 26 can move up or down simultaneously under the drive of the rotating shaft 24 .

A guide gasket 29 is provided on the outer wall of the lower end of the inner tube 21 corresponding to the outer tube 22 .

The rotating shaft 24 is a hexagonal rotating shaft.

Both the inner tube 21 and the outer tube 22 are square tubes.

The motor 23 is fixed on the lower surface of the desktop support 3 .

When the desktop needs to be raised, the motor 23 rotates forward, driving the rotating shaft 24 to rotate, and the engagement of the first bevel gear 25 and the second bevel gear 28 causes the screw rod 26 to rotate. Since the nut matched with the screw rod 26 is fixed, As a result, the screw rod 26 rotates and rises, thereby driving the outer tube 22 to rise to achieve the purpose of raising the desktop. When the desktop needs to be lowered, the motor 23 reverses to drive the rotating shaft 24 to rotate in the opposite direction. Through the engagement of the first bevel gear 25 and the second bevel gear 28, the screw 26 rotates in the other direction. The matched nut is fixed, so that the screw rod 26 rotates and descends, thereby driving the outer tube 22 to descend, so as to achieve the purpose of descending the desktop.

The utility model drives two table legs up and down simultaneously through a motor, has simple and reasonable structure, ingenious design, stable working performance, low product failure rate, and easy maintenance, which not only reduces production cost, but also reduces use cost.

As described in the embodiment of the utility model, other liftable dining tables with the same or similar structure as the utility model are all within the protection scope of the utility model.
