Detailed ways

Referring to Fig. 1 to Fig. 3, Fig. 1 to Fig. 3 are structural schematic diagrams of a specific embodiment of the present invention.

As shown in Fig. 1 to Fig. 3, a desk with a screw driving a screen to go up and down includes a desk panel 1 arranged horizontally and a supporting footboard 2 arranged vertically, the supporting footboard 2 is a sandwich structure with a hollow part, The hollow part of the supporting footboard 2 is provided with a lifting screen 3; it is characterized in that: a screw sleeve 4 is vertically arranged on the edge of the lifting screen 3, and a lifting wire is vertically arranged in the screw sleeve 4 Rod 5, the lower end position of the lifting screw 5 is fixedly arranged, and the lifting nut 5 is covered with a lifting nut, and the lifting nut is fixedly arranged in the screw casing 4; it also includes driving the lifting screw The drive motor 7 that the rod 5 rotates.

As preferably, it also includes a linkage rotating shaft 6 and a reversing drive 8. There are a plurality of lifting screw rods 5, and one reversing drive 8 is provided at the bottom of each lifting screw rod 5, and each The reversing drives 8 are all connected to the interlocking shaft 6 ; the interlocking shaft 6 is arranged horizontally, and the driving motor 7 is connected to the interlocking shaft 6 .

Specifically, as shown in Figures 1 to 3, each compartment has three said supporting footboards 2 altogether, wherein there is one said supporting footboard 2 in front of the seat, and then one said supporting footboard 2 is respectively arranged on both sides of the seat.

When working, the drive motor 7 drives the linked rotating shaft 6 to rotate, and then a plurality of the linked rotating shafts 6 pass through a plurality of the reversing drives 8 for reversing transmission, thereby driving a plurality of vertically arranged Lifting screw 5 rotates, and when described lifting screw 5 rotates, described lifting nut can lift and move on described lifting screw 5, because the lower end position of described lifting screw 5 is fixedly set, and described lifting nut is fixedly set In the screw sleeve 4 , the screw sleeve 4 can move up and down on the lifting screw 5 , so as to realize the lifting of the lifting screen 3 .
