Chinese utility model patent ublic specification of application CN204306304U discloses a kind of for children's myopia-preventing desk The liftable table leg of chair includes pedestal, and hollow support arm is fixed on pedestal, is sliding combined in support arm hollow interior Stent is equipped with screw riser in inner support, gearbox is equipped at the top of screw riser, gearbox is fixed on inner support Top.Although the utility model can be fitted together by being slidably matched, convenient for the adjustment of table height, stability is good, no Lateral deviation phenomenon can occur, controlled by motor, handling is good, and it is convenient to be moved forward and backward, and desk balance is easy to adjust.But this is System also has the following disadvantages:First, since screw riser is worm drive, the lifting speed of the lifting table leg is low, also Phenomena such as creeping is likely to occur, so as to cause user experience poor;Second, worn during worm drive it is larger, Service life is shorter.
Utility model content
The utility model for the above-mentioned prior art there are the problem of make improvement, i.e., technology to be solved in the utility model Problem is to provide a kind of electric elevatable table, is rotated by the engaged transmission band movable gear shaft of longitudinal bevel gear and lateral bevel gear, So as to which desktop be risen, gear ratio worm drive are more steady, and gearratio is accurate, reliable operation, efficient, long lifespan, knot Structure is compact, and power, speed and the size range used is wide, can preferably meet the needs of adapting to different user, by motor and The speed of the also adjustable desktop lifting of the setting of reduction box.
In order to solve the above technical problems, technical solution is to provide a kind of electric elevatable table used by the utility model, packet Include pedestal and desktop, the left and right sides of the base upper surface is respectively vertically arranged with first sleeve, in the first sleeve Movable sleeve is connected to the second casing, and the second casing upper surface is connected with the desktop, and the desktop is horizontally arranged, institute It states and motor and reduction box is installed in desktop, the projecting shaft of the reduction box front end is connected with longitudinal bevel gear, the longitudinal direction cone Gear front end is provided with lateral bevel gear, is arranged with gear shaft in the transverse direction bevel gear, the gear shaft lower part is set as Screw configuration, the gear shaft are arranged in standpipe, and the standpipe is fixed on the second casing center, the standpipe top vertically It holds and is provided with screw bolt seat, the screw portion of the screw bolt seat and the gear shaft is is threadedly coupled.
Preferably, the transverse direction bevel gear subjacent is provided with clutch shaft bearing.
Preferably, it is provided with second bearing below the clutch shaft bearing.
Preferably, being provided with the axle sleeve with the shaft shoulder on the outside of the gear shaft, the axle sleeve is fixed on described vertically On the inside of desktop, 3rd bearing is provided on the outside of the shaft shoulder.
Preferably, it is provided with fourth bearing on the outside of the longitudinal direction bevel gear.
In short, using a kind of electric elevatable table of the utility model, pass through the engagement of longitudinal bevel gear and lateral bevel gear Transmission belt movable gear shaft rotates, and so as to which desktop be risen, gear ratio worm drive are more steady, and gearratio is accurate, and work can It leans on, is efficient, long lifespan, compact-sized, power, speed and the size range used is wide, can preferably meet and adapt to different use The demand at family, the speed lifted by the also adjustable desktop of the setting of motor and reduction box.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples:
Fig. 1 is a kind of schematic diagram of electric elevatable table;
Fig. 2 is a kind of schematic diagram of electric elevatable table.
Wherein, pedestal 1, desktop 2, first sleeve 3, the second casing 4, motor 5, reduction box 6, longitudinal bevel gear 7 are laterally bored Gear 8, gear shaft 9, screw rod 10, standpipe 11, screw bolt seat 12, axle sleeve 13, the shaft shoulder 14, clutch shaft bearing 15, second bearing 16, third Bearing 17, fourth bearing 18.
Specific embodiment
