Description

Writing desk with adjustable tables panel of a bracket

Technical field

The utility model relates to a kind of writing desk with adjustable tables panel of a bracket, specifically, mainly is applicable to the writing desk that the student uses.

Background technology

As everyone knows, the people who bends over one's desk working for a long time on traditional writing desk because duplex and forearm are supported in reading and writing on the rectangular table panel, must adopt the sitting posture that excessively leans forward on the one hand, causes hunch and hypometropia; Because suspend the wrist operating computer keyboard and mouse make the muscle of shoulder back, arm, wrist be nervous shape for a long time, cause scapulohumeral periarthritis, cervical spondylopathy etc. on the other hand.

At present, existing a variety of table top set-ups of extending a bracket at desk near the horizontal table top panel edges of human body one side, in recent years, the drawer panel that also appears at horizontal table top plate drawer is provided with turnover level and props up the bracket structure, in fact, people are writing, need the horizontal table top plate during states such as operating computer keyboard and mouse, and read, need the slant desktop plate during drawing, according to the demand, the desktop of some writing desk is to make the level of can be adjusted to and heeling condition, therefore, existing level is propped up the bracket structure just can not adapt to the requirement of this class writing desk, and for example: the student learns the writing desk of usefulness.

Summary of the invention

The purpose of this utility model is to improve existing writing desk, and a kind of writing desk with adjustable tables panel of bracket is provided, a bracket is connected the top of the drawer panel inner plate surface of writing desk drawer with hinge, and can upwards overturn and also be supported on the end face of drawer panel inclination cantilever, make this bracket be the state of turning forward, can utilize again at the movable razor-edge liner on this bracket and insert between the end face of this bracket and inclination, this bracket is the level of state, in addition, also can make a bracket turn to user mode or hidden state.

The technical scheme that the utility model adopted: a kind of writing desk with adjustable tables panel of a bracket, but below desktop, be provided with the drawer of push-and-pull, its front is a drawer panel, the end face of this drawer panel is the downward-sloping oblique top face of front end, on the top of this drawer panel inner plate surface a hinged bracket is set, on the rail plate of the back side of this bracket, is provided with a wedge again.

The downward-sloping K degree of the oblique top face of described drawer panel and horizontal plane.

Described wedge is the straight tri-prismoid of an acute angle K degree.

Described the bracket back side also is provided with a cover elastic positioning pin.

Described bracket is separated into half bracket of half bracket in a left side and a right side, and forms the groove shape with drawer panel end face.

The upset that the utility model props up bracket does not take the space of drawer below, and can make a bracket adaptation level desktop and inclination desktop needs, and is simultaneously simple in structure, easy to use.

The specific embodiment

The utility model exemplary embodiments is to be made of a drawer 1, support 2, a desktop 3, bracket 4 and a wedge 5, shown in Fig. 1～4, wherein:

Drawer 1 is in below the desktop 3 that support 2 supported, and facing to the user of sitting posture, and again, this drawer 1 is in (not shown) on the longitudinal rail that desktop 3 is provided with below, can do forward and backward push-and-pull along the user towards sitting posture; Desktop 3 is the scalable or collapsible supports that utilize support 2 rear ends to support, desktop 3 can be up to the standard and tilt two states, when drawer 1 is worked for the user, deposit or take out file, instrument etc. easily, its front is that a drawer panel all belongs to prior art more than 11; The end face of this drawer panel 11 is the oblique top face (about 12 or 24 degree) of the downward-sloping K degree of front end.

Bracket 4 is that the left and right side by the plate face is vertical side, the front is a long horizontal edge for two hyphen limits and back separately, and mid portion is formed by inner concavity arc limit, and this bracket 4 is connected the top side location of the drawer panel 11 inner panel ends of drawer 1 with hinge (ready-made hinge, or dull and stereotyped hinge or bending hinge) at the end face at long horizontal edge place; When the user did not work, this bracket 4 was within the drawer 1, and at this moment, two pages of hinge are merged together (being that its mitre joint is bordering on 0 °).

When the user to read, when drawing, pull the drawer out 1 earlier, the pivot that a bracket 4 is wrapped page or leaf upwards turns, at this moment, a plate face that props up bracket 4 contacts and is supported on the oblique top face of drawer panel 11, then, drawer 1 is pushed below the desktop 3, till propping up bracket and desktop is received together mutually, at this moment, a bracket 4 is approximately consistent with desktop 3 heeling conditions, and the contact-making surface of a bracket is identical or high slightly with the contact-making surface height of desktop, so user's duplex and forearm are supported on the bracket 4, read, need when drawing for the user; When the user quits work, bracket 4 by and aforementioned reverse turn, and it is entered in the drawer 1, last, big drawer 1 is pushed below the desktop 3, find out thus, prop up the upset of bracket 4, do not take the space of drawer 1 below;

Wedge 5 is straight tri-prismoids of an acute angle K degree (about 12 or 24 degree), be connected bracket 4 back side with rail plate (perhaps with rotating shaft) perpendicular to bracket 4 a plate face, do not unclamp in order to ensure wedge 5 wedgings, at bracket 4 back side one cover elastic positioning pin 6 is set also, as becoming with compression spring set with ball;

When the user will write, when operating computer keyboard and mouse, lift a bracket 4 with hand, and promote (perhaps rotating) wedge 5 between the oblique top face of a bracket 4 and drawer panel 11 around vertical rotating shaft, a bracket 4 is in desktop 3 is equal height or high slightly level, and the ball of elastic positioning pin 6 is under the pressure of compression spring, automatically be resisted against wedge 5 ends, in case wedge 5 unclamps.
