Description

The drawing table of local adjustment height angle

Technical field

The utility model relates to a kind of drawing table, especially a kind of drawing table of the local adjustment height angle that can regulate the height of local location on desktop, angle.

Background technology

At present, known existing drawing table in use, direction, the angle of inclination and the height of lifting that desktop tilts are all fixed, it is only the adjusting of single direction, and the regulatable scope that existing drawing table limits is all basically identical, these drawing tables can not meet adjusting in any situation of user, arbitrarily angled height, and need user to deacclimatize the angle that desk has designed in advance; And existing a small amount of drawing table has been considered the problem of user for article storage, but the grids that adopt hold more, or baffle plate holds, what this mode was brought is the minimizing to whole size of desktop, and this is very inconvenient for drawing performance; And for the people who needs pigment drawing for some, with baffle plate, fixedly go out grid, while looking for the pigment of different colors, may need very high position, visual angle the scope in grid could be covered all at one glance, and these bring inapplicable, unpractical user to experience to user undoubtedly, had a strong impact on people's study and drawing efficiency, really to masses, do not brought the real scheme of dealing with problems, thereby also caused the common low present situation of drawing table utilization rate.

Utility model content

For solve existing drawing table can not meet drawing user desktop is adjusted to various angles, the problem of height, the utility model provides a kind of drawing table of local adjustment height angle, the drawing table of this part adjustment height angle, can normal use as common writing desk, desktop does not have baffle plate and the grid can putting on article yet, and can carry out multi-direction to local desktop, multi-angle, comprehensive, independently, random angle adjustment, to meet the demand of drawing user to various angles, and can also carry out random adjustment to the height of desktop, reach and make everyone desktop can be adjusted to the height of own the most comfortable and the object of angle, applied widely, and operating process is convenient, simply, safety, laborsaving, brought real convenience and convenient to people's study and drawing.

The utility model solves the technical scheme that its technical problem adopts: the drawing table of this part adjustment height angle comprises desktop, lamp house, drawer, upper support bar a, central supported a, hold-down nut, fixing silk, table leg, forward screw rod, positive silk nut, an anti-nut, counterscrew, crank, upper support bar b, central supported b, cross bar, baffle plate; The drawing table of this part adjustment height angle is provided with a smooth desktop, desktop middle part hollow out, hollow part coincide and is provided with drawer, the top of drawer is lamp house, lamp house inside is provided with LED lamp, lamp house top be coated with one with the identical safety glass of desktop middle part hollow part, LED lamp can see through glass to external exposure, safety glass surface with table-top surface in same level;

In bottom, two ends, desktop left and right, be connected with central supported a, central supported b, the mid portion of central supported a and central supported b is provided with the hollow slots that is runway shape, can coincide hold-down nut let alone to slide up and down of this groove; Central supported a is respectively provided with a horizontal baffle plate parallel with desktop with the outside of central supported b, baffle plate, both sides are connecting the as a whole structure of cross bar of table leg and bottom, the middle of two baffle plates is respectively provided with a through hole, and respectively there is the fixing silk that a band revolves handle respectively through two through holes, to be fixed with the hold-down nut of central supported a5, central supported b and strap bolt cap respectively, by fixing silk, loosen hold-down nut, can move up and down central supported a and central supported b, then adjust height and the angle of desktop;

Baffle plate each side have a through hole, be used between two baffle plates respectively through a screw rod, screw rod one end-stopping plate is respectively provided with spiro rod cap outward screw rod is fixed, the baffle plate outside of the other end of screw rod is respectively fixedly connected with a crank, each screw rod is divided into left and right two parts, be forward screw rod and counterscrew, and corresponding positive silk nut and the anti-silk nut of being fitted with respectively, above positive silk nut and anti-silk nut, each is hinged and is connected to a upper support bar a and upper support bar b, upper support bar a and upper support bar b upper end are hinged and connected on the junction button of drawer bottom, and supporting drawer, when two rocking bars shake simultaneously, drive positive silk nut and anti-silk nut simultaneously mutually near or away from, when close, positive silk nut and anti-silk nut promote upper support bar jack-up drawer, form raising of local desktop, when away from time, local desktop falls after rise, when only one of them crank being shaken to operation, just make the angled adjusting of local desktop type,

The operation of cooperation to central supported a, central supported b, can reach the Integral diagonal position degree of whole table surface, the adjusting of height; Or only local desktop is regulated, so both retained the desk function of putting on article around, can carry out drawing performance again; When turning on LED lamp, just can carry out the Plot Work of the specialties such as duplicating image.

The beneficial effects of the utility model are, the drawing table of this part adjustment height angle, the use function of the conventional tables both having retained, limitation and the drawback of existing drawing table have been improved greatly again, can carry out multi-direction to local desktop, multi-angle, comprehensive, independently, random angle adjustment, to meet the demand of drawing user to various angles, and can also carry out random adjustment to the height of desktop, reach and make everyone desktop can be adjusted to the height of own the most comfortable and the object of angle, applied widely, and operating process is convenient, simply, safety, laborsaving, brought real convenience and convenient to people's study and drawing.
