The invention has the beneficial effects as follows：1st, simple structure, low production cost improves the market competitiveness.2nd, motor and driving
Decelerator is provided between screw mandrel, it can effectively reduce the resistance of motor operation so that the lowering or hoisting gear in this case can steadily pacify
Quiet operation.3rd, decelerator be arranged on left and right two Convenient tables in the middle of, it is located at the inside of main support, therefore, its be easy to outward
While shell is installed, be conducive to the Differential Output of power.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is gearbox designs schematic diagram in the present invention.
Fig. 3 is Convenient table in the present invention and lifting leg installation diagram.
Specific embodiment
Make concrete further instruction to the present invention below in conjunction with the accompanying drawings.A kind of electric elevatable table driving structure, its feature
It is：It includes being set with lifting leg 3 in main support 1 and the Convenient table at its corner 2, Convenient table 2, sets in Convenient table 2
It is equipped with lifting screw 4 and is spirally connected with the nut 5 being arranged in lifting leg 3；Driven angular wheel is installed on described lifting screw 4
41 engage with the active angular wheel 6 in Convenient table 2 is arranged, and gearbox 7, gearbox both sides are provided with described main support 1
Extend drive link 8 to be connected with the active angular wheel 6 in two Convenient tables of left and right, described gearbox 7 is by drive link 8 and drive
Dynamic motor 9 connects.
Described gearbox 7 is arranged on the point midway of two Convenient tables 1 of left and right, and gearbox 7 is fixed on main support 1.
Described gearbox 7 is including main box 71 and sets first stud gear 72 in the inner and second stud gear 73, the
First, two change-speed gearings 72,73 are symmetrically mounted in main box 71, and by the initiative taper in two Convenient tables of drive link 8 and left and right
Shape gear 6 is engaged, and is connected by the 3rd change-speed gearing 74 between first and second change-speed gearing 72,73, and the 3rd change-speed gearing 74 is by passing
Lever 8 is connected with motor 9.
First, second and third described change-speed gearing 72,73,74 is bevel gear.
The main frame 11 of described main support 1 an including quadrangle and the cross bar 12 being laterally distributed in it, Convenient table 2 is pacified
It is mounted at the corner of main frame 11.
Operation principle：When lifting is needed, motor drives the 3rd change-speed gearing 74 in gearbox to rotate by drive link,
When 3rd change-speed gearing is rotated, first and second change-speed gearing for engaging is driven to rotate, wherein due to the tooth of the 3rd change-speed gearing
Number is less than the number of teeth of first and second gear, therefore the gearbox in this case can play reduction revolution, increases the effect of torsion.So as to
Meet the use demand of same table low-speed heave-load, it is to avoid in traditional structure, motor is easy to the drawbacks of overload burning occur, extend
The service life of this product.
Wherein it should be noted that the gearbox in this case is arranged between two Convenient tables of left and right, and motor is located at main
Inside frame, therefore it can guarantee that the transmission of Convenient table to the left and right of dynamic equilibrium, so as to ensure that four lifting legs are synchronized with the movement.And
Motor is located inside main support, has also allowed for installing Decorative Cover etc. outside this structure, so as to lift efficiency of assembling.
Wherein it should be noted that：The power exported from gearbox is delivered to the initiative taper in Convenient table by drive link
Shape gear 6, when active angular wheel 6 is rotated, drives the driven angular wheel 41 for engaging and lifting screw 4 to rotate, and lifts
Screw rod 4 interacts when rotating with nut 5, so as to drive lifting leg to make elevating movement in Convenient table, realizes the upper of desktop
Rise and decline effect.In addition, in order to ensure that four lifting legs are synchronized with the movement, two lifting legs on same long side are passed through in this case
Connecting rod and angular wheel mechanism connect, therefore speed changer is when driving any one lifting screw to rotate, by gear and connecting rod
Mechanism drives remaining lifting leg motion.Compared with conventional art, simple structure in this case, power is evenly distributed balance, compact
Structure also help and the assembling of other accessories, so as to lift efficiency of assembling, reduce production cost, therefore can be widely popularized and use.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.
