Description

Adjustable table board

The utility model relates to a kind of improvement of Bureau plate.

Existing Bureau plate has only a kind of, is to be lumped together by a glass and a fiberboard, keeps flat on the table, makes office face smooth.But this platen can only keep flat on the table, so the clerical workforce is when writing, and neck and waist must have certain bending, and this eyesight to them, psoas all have infringement.

The purpose of this utility model is to avoid having the shortcoming that Bureau plate can only keep flat now, can at random regulate the angle of platen and desktop within the specific limits, and does not influence desktop placement thing.Protection clerical workforce's eyesight, psoas, it is comfortable to play office, the effect of increasing work efficiency.

With accompanying drawing the technical solution of the utility model is described below.

Accompanying drawing mark sequence number is expressed as follows respectively:

1. underframe, 2. article rack, 3. platen, 4. hinge, 5. underframe is regulated screw, and 6. underframe is regulated bolt, 7. regulating block, 8. platen adjustment hole, the 9.M10 nut, 10. platen is regulated bolt, 11. flanges, 12. rivets, 13.M4 nut, 14. little iron nails, 15. splicing lines.

Description of drawings: by underframe 1 and article rack 2 that thin guiding principle plate is made, wherein 1 a, b both sides are converted into the right angle respectively downwards, and the following folding part branch on b limit has two underframe at a distance of g to regulate screw 5.Article rack 2 is contained on the underframe 1, and the distance on its center line and a limit is f, connects with M4 nut 13 and sunk screw.Platen 3 usefulness planks are made, and connect with underframe 1 with hinge 4, and the distance on the axis of hinge 4 and a limit is d.Wherein underframe 1 and 12 riveted joints of hinge 4 usefulness rivets, platen 3 and hinge 4 usefulness wood screws are fixed.All there is flange 11 on four limits of platen 3, fix with little iron nail 14.Two broadside front ends of platen 3 respectively have a regulating block 7, are fixed on its below with wood screw.Extension at regulating block 7 also has a platen adjustment hole 8 respectively, and on platen adjustment hole 8 a M10 nut 9 is arranged respectively again.

When using described platen, underframe 1 is comprised platen 3, install as stated above, be put on the desk together.1 reverse side contact desktop, twice the folding parts branch just in time blocks the desk two edges.As gapped, available two underframe are regulated bolt 6 and are compressed the desk edge by two underframe adjusting screws 5, and underframe is fixed tightly on the desk.Then two platens are regulated in two M10 nuts 9 of bolt 10 difference precessions, and rotation (utilizing the characteristics of the rotation straight-line displacement of screw thread), platen 3 can be that angular adjustment is made in the center of circle with the hinge axis just like this, reaches the purpose that platen is tilted.If exist the gap because platen is regulated between the screw thread of bolt 10 and M10 nut 9, and when rocking, can below regulating block 7, increase a M10 nut 9 again, and tighten.The gradient that (depends on 10 length) within the specific limits and regulate platen 3 arbitrarily both can keep flat, and whole platen can also be taken away from desktop, and was flexible.Article rack 2 can be placed the office accommodation of a little indispensabilities.

The utility model is compared existing platen, have comfortable attractive in appearance, flexible, function congruence advantage.And platen is wooden edge, and clothes, skin are not all had to damage.Applicable to multiple occasions such as office, classroom, families, be convenient to office greatly, write.

Embodiment: a kind of by thick underframe 1 and the article rack of making for the sheet metal of (1～2) mm 2.Wherein underframe 1 can be with the method for welding, and steel plate bar that will (70～100) mm is combined into the periphery, and its twice folding parts divide the wide 20mm that is, two underframe adjusting screws 5 apart from g=(600～700) mm.The width of whole underframe 1 is (90～110) mm, and length will be made plurality of specifications (is a specification with 20mm), can adapt to the desktop of different in width.Article rack 2 is apart from height h=(140～160 of underframe 1) mm, width e=140mm, center line and a limit apart from f=540mm, its two footing connection holes apart from l=600mm.Platen 3 usefulness are thick makes (as two wood board splicings of need, must press the splicing method splicing of splicing line 15), its length p=700mm, width c=400mm for the wooden plank more closely of 12mm.The middle wheelbase a limit d=60mm of hinge 4, the connection holes of platen 3 and hinge 4 is (20～22) mm with the k back gauge of platen 3.Flange 11 is selected the wide 15mm that is for use, and thick is the 6mm batten.Bolt 6 regulated by underframe and platen adjusting bolt 10 is closely-pitched, full screw thread, diameter 10mm entirely, and length is respectively 20mm, 200mm.Regulating block 7 is selected the thick little steel plate of (2～3) mm for use, and wide is (20～30) mm, and its extension length is 20mm, and the diameter of platen adjustment hole 8 is 12mm, and M10 nut 9 is welded on the top of platen adjustment hole 8.Below platen 3, each regulating block becomes " △ " shape to fix with 3 wood screws with 6 wood screw secured adjusted pieces 7.
