Specific embodiment
The embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, but is not limited to the model of the utility model
It encloses.
As shown in Figs. 1-2, the utility model provides a kind of electric elevatable table, including pedestal 1 and desktop 2, on the pedestal 1
The left and right sides on surface is respectively vertically arranged with first sleeve 3, and movable sleeve is connected to the second casing 4, institute in the first sleeve 3
It states 4 upper surface of the second casing and is connected with the desktop 2, the desktop 2 is horizontally arranged, and electricity is equipped in the desktop 2
Machine 5 and reduction box 6, the projecting shaft of 6 front end of reduction box are connected with longitudinal bevel gear 7, and 7 outside of longitudinal direction bevel gear is set
There is fourth bearing 18, longitudinal direction 7 front end of bevel gear is provided with lateral bevel gear 8, gear is arranged in the transverse direction bevel gear 8
Axis 9, the transverse direction bevel gear 8 subjacent setting clutch shaft bearing 15,15 lower section of clutch shaft bearing are provided with second bearing 16,
The outside of the gear shaft 9 is provided with the axle sleeve 13 with the shaft shoulder 14, and the axle sleeve 13 is fixed on 2 inside of desktop vertically,
14 outside of the shaft shoulder is provided with 3rd bearing 17, and the shaft shoulder 14 is conducive to avoid the bearing using oversized dimensions, in this way meeting
It saves material and improves the precision of bearing, 9 lower part of gear shaft is set as 10 shape of screw rod, and the gear shaft 9 is arranged on
In standpipe 11, the standpipe 11 is fixed on 4 center of the second casing vertically, and 11 top of standpipe is provided with screw bolt seat 12,
10 part of screw rod of the screw bolt seat 12 and the gear shaft 9 is is threadedly coupled.
Working method:After powering on, the projecting shaft of 6 front end of reduction box persistently drives longitudinal bevel gear 7 to drive lateral cone
Gear 8 rotates, so as to which screw rod 10 be driven to be moved up and down in standpipe 11, when screw rod 10 rises desktop 2, and the second casing 4
Also it can rise.
The beneficial effects of the utility model are:Pass through the engaged transmission band movable gear shaft of longitudinal bevel gear and lateral bevel gear
Rotation, so as to which desktop be risen, gear ratio worm drive are more steady, and gearratio is accurate, reliable operation, efficient, service life
Long, compact-sized, power, speed and the size range used is wide, can preferably meet the needs of adapting to different user, pass through electricity
