Abstract
A kind of rotary limited Folding desk, it is by objective table, desk panel, rotating shaft 1, screens switch block, secondary slide rail rotating disk, interior pillar, outer pillar, tooth bar, gear, removable bayonet lock, base, inner orbit projection, wedge-shaped impression, outside track, outside track lower convexity, rotating shaft 2, wedge-shaped impression end 1, wedge-shaped impression end 2 forms.This desk is different from traditional Folding desk, and it does not need support to support desk panel, only needs manually to rotate desk panel and objective table just can realize the expansion of desktop and objective table with folding; And the position manually regulating desk bottom to move bayonet lock can make whole desk along the rack-track lifting in pillar and then the adjustment realizing desk height.The utility model desk is rational in infrastructure, simple to operate, be convenient to arrange to arrange, facilitate personnel to circulate, and efficiently solving narrow space and desk height between classroom seat can not the problem of adjusted in concert.
Description
Technical field
The utility model relates to a kind of desk, particularly a kind of rotary limited Folding desk.
Background technology
Desk is the requisite part in classroom, closely bound up with the normal learning life of student.But many drawbacks such as the widely used classical desk of school total Existential Space utilization of resources is at present unreasonable, heavy, mobile inconvenience, the existence personnel that often cause of these drawbacks are detained and handicapped, and also easily stumble when Cleaner cleans between different desk gap.In addition, desk in the market, it is highly mostly fixing, often cannot form reasonable coordination with student's height, if things go on like this, will inevitably cause a large amount of sitting posture of student not just, the problem such as visual impairment.
Summary of the invention
For the problems referred to above, the utility model provides that a kind of reliability is high, the rotary limited Folding desk of high-effective and labour-saving.
The utility model solves the technical scheme that its technical problem adopts: it is by objective table, desk panel, rotating shaft 1, screens switch block, secondary slide rail rotating disk, interior pillar, outer pillar, tooth bar, gear, removable bayonet lock, base, inner orbit projection, wedge-shaped impression, outside track, outside track lower convexity, rotating shaft 2, wedge-shaped impression end 1, wedge-shaped impression end 2 forms.Objective table is positioned at the below of desk panel; The both sides of desk panel are connected with secondary slide rail rotating disk respectively, and the secondary slide rail rotating disk center of circle is connected with interior pillar upper end by axle; The both sides of objective table are connected with secondary slide rail rotating disk respectively, and the secondary slide rail rotating disk center of circle is connected with two interior pillar middle-ends by axle; Screens switch block geometric center is connected with secondary slide rail rotating disk by axle; A gear is fixed in interior pillar bottom, and a tooth bar is fixed in an outer column wall side, and inside and outside pillar is engaged by wheel and rack, and removable card pin card is between rack and pinion.The lower end of outer pillar is connected with base.
The beneficial effects of the utility model are, during use, desk panel is upwards turned to and exceedes horizontal level, the outside track lower convexity of secondary slide rail rotating disk promotes the wedge-shaped impression 2 of screens switch block, when desk panel returns to horizontal level, the wedge-shaped impression 1 of screens switch block is stuck in the inner orbit projection place of secondary slide rail rotating disk just, and desk panel is in horizontal service position; Profit can make objective table be in horizontal service position in the same way; Time folding, desk panel is upwards turned an angle, thus makes the lower convexity of secondary slide rail rotating disk promote the wedge-shaped impression 2 of screens switch block, make wedge-shaped impression end 1 turn over inner orbit projection place, screens switch block enters the outside track of secondary slide rail rotating disk, and desk panel is swung down to folded state; Profit makes objective table be in folded state in the same way.When regulating desk height, by the outwards movement of removable bayonet lock, move up and down interior pillar, interior pillar bottom gear moves up and down along tooth bar, after arriving correct position, expense is inwardly inserted, rack-and-pinion is fixed, thus reaches the object regulating desk height.
The utility model is rational in infrastructure, simple to operate, be convenient to arrange to arrange, facilitate personnel to circulate, and efficiently solving narrow space and desk height between classroom seat can not the problem of adjusted in concert.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model, and Fig. 2 is rotary position-limit mechanism schematic diagram, and Fig. 3 is desk height adjustment mechanism schematic diagram.
In Fig. 1, Fig. 2, Fig. 3,1. objective table, 2. desk panel, 3. rotating shaft Isosorbide-5-Nitrae. screens switch block, 5. secondary slide rail rotating disk, 6. pillar in, 7. outer pillar, 8. tooth bar, 9. gear, 10. removable bayonet lock, 11. bases, 12. inner orbit projections, 13. wedge-shaped impressions, 14. outside tracks, 15. outside track lower convexity 16. rotating shaft 2,17. wedge-shaped impression end 1,18. wedge-shaped impression ends 2.
Detailed description of the invention
It is by objective table (1), desk panel (2). rotating shaft 1(3),. screens switch block (4). secondary slide rail rotating disk (5), interior pillar (6),. outer pillar (7). tooth bar (8), gear (9), removable bayonet lock (10). base (11), inner orbit projection (12), wedge-shaped impression (13), outside track (14), outside track lower convexity (15), rotating shaft 2(16), wedge-shaped impression end 1(17) and wedge-shaped impression end 2(18) composition.During use, desk panel (2.) is upwards turned to and exceedes horizontal level, now the outside track lower convexity (15) of secondary slide rail rotating disk (5) promotes the wedge-shaped impression 2(18 of screens switch block (4)), when desk panel (2.) returns to horizontal level, the wedge-shaped impression 1(17 of screens switch block (4)) be just stuck in inner orbit projection (12) place of secondary slide rail rotating disk (5), desk panel (2.) is in horizontal service position; Profit makes objective table (1) be in horizontal service position in the same way; Time folding, desk panel (2.) is upwards turned an angle, thus make the outside track lower convexity (15) of secondary slide rail rotating disk (5) promote the wedge-shaped impression end 2(18 of screens switch block (4)), wedge-shaped impression end 1 is made to turn over inner orbit projection place (12), screens switch block (4) enters the outside track (14) of secondary slide rail rotating disk (5), and desk panel (2) is swung down to folded state; Profit makes objective table (1) be in folded state in the same way.When regulating desk height, by removable bayonet lock (10) outwards movement, move up and down interior pillar (6), interior pillar (6) bottom gear (9) is moved up and down along tooth bar (8), after arriving correct position, removable bayonet lock (10) is inwardly inserted, gear (9) tooth bar (8) is fixed, thus reach the object regulating desk height.The utility model is rational in infrastructure, simple to operate, be convenient to arrange to arrange, facilitate personnel to circulate, and efficiently solving narrow space and desk height between classroom seat can not the problem of adjusted in concert.
