DETAILED DESCRIPTION

[0017] The utility model discloses the beneficial effect is:

[0018] As Figures 1-5As shown, a liftable display support, including base 2, the inside of base 2 has a cavity, the upper surface of base 2 is provided with shell 3, the outer surface of shell 3 is symmetrically provided with through slot, the inside of shell 3 is rotatably connected with lead screw 4, the lower end of lead screw 4 penetrates through base 2 and extends to the inside of base 2, the upper end of lead screw 4 is threadedly connected with sliding block 5, further including mounting plate 6 fixedly connected with display, one side of mounting plate 6 is symmetrically provided with two supporting plates 7, one end of supporting plate 7 penetrates through the through slot of shell 3 and is fixedly connected with sliding block 5, the lower end of lead screw 4 is provided with driven gear 8, driven gear 8 is located in the inside of base 2, the cavity of base 2 is provided with driving gear 9 engaged with driven gear 8, the outside of base 2 is provided with knob 10 fixedly connected with driving gear 9, the number of teeth of driven gear 8 is greater than that of driving gear 9.

[0019] Base 2 is placed on table plate 1, display is fixed on mounting plate 6, when the height of display needs to be adjusted, only need to rotate knob 10, knob 10 will drive driving gear 9 to rotate when rotating, and drive lead screw 4 to rotate through the engagement between driving gear 9 and driven gear 8, since lead screw 4 is threadedly connected with sliding block 5, and the rotation of sliding block 5 is limited through supporting plate 7 and through slot, therefore, lead screw 4 can drive sliding block 5 to make lifting movement on shell 3 when rotating, sliding block 5 can drive display to move through supporting plate 7 when making lifting movement on shell 3, so as to change the height of display.

[0020] Further, the upper and lower sides of sliding block 5 are respectively provided with folding tubes 11, lead screw 4 is located in the inside of folding tube 11, the upper end of folding tube 11 located above sliding block 5 is fixedly connected with the inner top of shell 3, the lower end of the other folding tube 11 is fixedly connected with the inner bottom of shell 3, folding tube 11 is rubber tube or plastic tube, the inner surface of folding tube 11 does not contact with the outer surface of lead screw 4, folding tube 11 can avoid dust in air from adhering to the outer surface of lead screw 4, so as to improve the smoothness of the surface of lead screw 4, make the cooperation between lead screw 4 and sliding block 5 smooth, and the lower end of folding tube 11 located above can be provided with annular magnet, the magnet can be magnetically attracted on sliding block 5, by moving the magnet on sliding block 5, the outer surface of lead screw 4 is exposed, then appropriate amount of lubricating oil is injected to the outer surface of lead screw 4, then the magnet is continuously magnetically attracted on sliding block 5, then by controlling the up and down movement of sliding block 5, the lubricating oil can be relatively uniformly coated on the outer surface of lead screw 4, which is convenient for maintaining lead screw 4.
