The purpose of this utility model is to realize by following technical proposals:
A kind of novel screw type lifting school desk, comprises a body and desk support, and described table body bottom is threaded by double threaded screw with desk support, and the thread rotary orientation of the top and bottom of double threaded screw is not identical, has Handheld Division between top and bottom.
The different thread rotary orientation in double threaded screw top and bottom makes, in the time utilizing Handheld Division to rotate double threaded screw, to realize the lifting of table body.
As preferably, described table body bottom is provided with support swivel nut, and desk cantilever tip is provided with lower support swivel nut, the upper end of double threaded screw is threaded with upper support swivel nut, lower end is threaded with lower support swivel nut, and the upper end of double threaded screw is right-handed thread, and lower end is left hand thread.
Upper support swivel nut plays the effect that table body is supported, and lower support swivel nut plays the effect to desk stent support.
As preferably, described upper support swivel nut and lower support swivel nut both sides are provided with bearing rib.
This bearing rib can play strengthens the upper effect of supporting swivel nut and lower support swivel nut rigidity, also has the effect of support and stabilized table body simultaneously.
As preferably, the thread jacket of two ends up and down of described double threaded screw connects threaded cover.
This threaded cover has the effect that covers double threaded screw thread segment, avoids screw thread to expose, and ensures attractive in appearance; Also play dustproof effect, avoid dust to fall into double threaded screw thread segment, cause screw thread to have some setbacks, rotate dumb simultaneously.
As preferably, described table body front is provided with two drawers, in drawer, along extracting direction out, chute is set, and on chute, movable assembling is every book plate.
For blocking the book that is placed on drawer, make book discharge neat every book plate.
