Described lower table leg bottom is provided with foot pad, can increase the frictional force on table leg and ground, increases desk stability, avoids table leg to cause damage to ground friction simultaneously.

On at least one lower table leg, be provided with the locking nut that can lock corresponding upper table leg. Make desktop more steady, easy to use.

Described desktop is composited by glass surface and wood plate surface. Different material layers is applicable to different functional requirements, and for example, glass surface is suitable as tea table and uses, and wood plate surface is more suitable for using as dining table.

Described worm screw upper surface is provided with elastomeric layer, for example, can be rubber blanket, reduces the squeezing action to desktop, avoids desktop to form and damage.

Described rocking handle is installed on the middle part of the cross bar that connects two adjacent lower table legs.

Described cross bar has two, be arranged in parallel, and two cross bars middle part connects to form one I-shaped by a vertical pole.

Worm gear is installed at the middle part of described vertical pole, worm gear be positioned at desktop center under, be conducive to the steady lifting of desktop.

The lifting of desk is to be realized by worm-and-wheel gear, unclamp the locking nut on lower table leg, shake rocking handle, drives worm gear rotation by connecting rod, thereby drives worm screw to rotate, desktop is raise or reduce, by the auto-lock function of worm and gear, can make desk be fixed on arbitrary height, for preventing that upper table leg from rocking, two locking nuts can simultaneously tightening diagonal angle on lower table leg, fix lower table leg.

Desktop is supported by two A-frames, and two A-frames are separately fixed on the lagging of the upper table leg left and right sides by two bolts separately, has an axle above each A-frame drift angle, and desktop can pivot. Two locking nuts tightening diagonal angle on lower table leg, fix lower table leg. Four of desktop angles are fixed and are supported by four draw-in grooves at ordinary times, and desktop when upset, draw-in groove horizontally rotates, and desktop departs from, and shake rocking handle, till worm screw being dropped to do not affect desktop upset. Now desktop only has two axles on A-frame to support, and can carry out 180 rotations. After having rotated, four draw-in grooves of four jiaos reset, and again block desktop.

The utility model is simple in structure, liftable easy to use, the desk that simultaneously desktop can 180 degree upsets. Can be placed in the room that area is less and use, desk reduces at ordinary times, and glass surface upward, uses as tea table, and while having a meal, desk raises, and desktop turns over turnback, and wood plate surface upward, is used as dining table.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, the turnover lifting desk of desktop, comprise the table leg nesting together up and down, wherein upper table leg 8 is inserted in lower table leg 9, and can in lower table leg 9, move up and down, a rocking handle 11 is installed on lower table leg 9, rocking handle 11 is connected with worm gear 15 by connecting rod 13, worm gear 15 is meshed with worm screw 2 lower ends that vertically arrange, and worm screw 2 upper ends contact with desktop 5;

The draw-in groove 6 that the corner of desktop 5 can horizontally rotate by upper table leg 8 tops blocks, and the dual-side middle part that desktop 5 is relative is movably connected on the drift angle of A-frame 4 by 7 axles, and A-frame 4 bases are fixed on upper table leg 8.

Upper and lower table leg 8,9 correspondences are provided with four, meet conventional use habit, are conducive to desk monolithic stability and attractive in appearance. Lower table leg 9 bottoms are provided with foot pad 16, can increase the frictional force on table leg and ground, increase desk stability, avoid table leg to cause damage to ground friction simultaneously.

On at least one lower table leg 9, be provided with the locking nut 10 that can lock corresponding upper table leg 8. Make desktop more steady, easy to use.

Desktop 5 is composited by glass surface and wood plate surface. Different material layers is applicable to different functional requirements, and for example, glass surface is suitable as tea table and uses, and wood plate surface is more suitable for using as dining table.

Worm screw 2 upper surfaces are provided with elastomeric layer, for example, can be rubber blanket, reduce the squeezing action to desktop, avoid desktop to form and damage.

Rocking handle 11 is installed on the middle part of the cross bar 12 that connects two adjacent lower table legs 9.

Cross bar 12 has two, be arranged in parallel, and two cross bar 12 middle parts connect to form one I-shaped by a vertical pole 14.

Worm gear 15 is installed at the middle part of vertical pole 14, worm gear 15 be positioned at desktop 5 centers under, be conducive to the steady lifting of desktop 5.

The lifting of desk is to be realized by worm-and-wheel gear, unclamp the locking nut 10 on lower table leg 9, shake rocking handle 11, drives worm gear 15 to rotate by connecting rod 13, thereby drives worm screw 2 to rotate, make desktop 5 raise or reduce, by the auto-lock function of worm and gear, can make desk be fixed on arbitrary height, for preventing that upper table leg 8 from rocking, two locking nuts 10 can simultaneously tightening diagonal angle on lower table leg 9, fix lower table leg.

Desktop 5 is supported by two A-frames 4, and two A-frames 4 are separately fixed on the lagging 3 of the upper table leg left and right sides by two bolts 1 separately, above each A-frame 4 drift angles, have an axle 7, and desktop 5 can rotate around axle 7. Two locking nuts 10 tightening diagonal angle on lower table leg, fix lower table leg. Four of desktop 5 angles are fixed and are supported by four draw-in grooves 6 at ordinary times, and when desktop 5 overturns, draw-in groove 6 horizontally rotates, and desktop 5 departs from, and shake rocking handle 11, till worm screw 2 being dropped to do not affect desktop 5 upsets. Now desktop 5 only has two axles 7 on A-frame 4 to support, and can carry out 180 rotations. After having rotated, four draw-in grooves 6 of four jiaos reset, and again block desktop 5.
