Summary of the invention
Cannot fold to overcome existing desk and chair, height can not be regulated, usable floor area cannot change, the deficiency of inconvenience movement, the utility model provides a kind of Foldable multifunctional desk and chair, and this desk and chair can not only hand foldable, and can be adjusted to differing heights according to demand, can area increased as required, moved freely by pulley.The technical scheme that the utility model solves the employing of its technical problem is:
Have chute, slide bar inside the utility model desk two side stand, pedestal upper end has space, can around the desk panel of side holder pivots.Drawer-bottom board can under force along two wood side-guide upward slidings to being close on the downside of desk panel. and desk one side stand is connected through the hinge a slide bar, and the slide bar other end is being embedded in the chute inside opposite side support.Have locking device to be locked when not using and avoid sliding, say when needing that snap close is opened, slide bar can around hinged end upward sliding.Under the drive of slide bar, the removable side stand of desk can be drawn close to the other end by the chute on the downside of panel, until fit with opposite side.Both sides pedestal upper end has the rectangle space be consistent with drawer-bottom board size thickness, and when a side stand moves to opposite side, base plate can stretch out from space.Last drawer-bottom board and desktop overturn 90 degree downwards under gravity automatically to parallel with support.One piece of surface plate of folding final one-tenth very thin thickness.
Desk two side stand portion on the lower side has third gear spring heights to regulate PBU pushbutton unit.Support has three circular holes, PBU pushbutton unit is enclosed within hollow sting.Pressing button both sides, the thin rod part be connected to after button under spring contraction divides the junction, gap arrived between circular hole, thus can slide up and down to different shelves.The desk top be connected to by key device up-down adjustment can regulate object highly to different shelves to reach.
Desk both sides frame bottom has pulley, not the used time rotatable enter in hollow sting, ensure stability when desk uses and can not slide.Screwed out by pulley by the handle be exposed on the external when needing slip, then desk class is free to slide to facilitate movement.
Desktop has the flat board connected by parallel hinges, the dull and stereotyped rotation by hinge realizes the up-down adjustment of height.Flat board there is the book supporting board of inclination, check to facilitate during pupil drawing above book and atlas can be placed on.Desktop has turnover panel near both sides, user side, uses cross gemel connection, upwards can overturn 90 degree to parallel with desktop, enlarging table top area when needing.
Slide bar is devised, the turnover chair back between chair two side stand of the present utility model, can around the chair panel of side holder pivots.Folding mode and desk similar: the chair back overturns 90 degree downwards to fitting with chair seat by hinge.And have locking device after the chair back, fixing when not needing folding, stability and the fastness of use can not be affected.Slide bar between support around one end hinge rotate, the other end inside opposite side support in chute on slide.Can draw close to opposite side by the chute on the downside of panel, until be close to opposite side support at the drive lower carriage of slide bar.The chair back of laminating is with seat can upset 90 degree be downwards extremely vertically parallel with support automatically under gravity.Finally be folded into the plane tabular of one piece of very thin thickness.
The utility model has the difference of prior art to be mainly the difference of folding mode and the High Level of folding degree compared with the prior art.Existing Folding desk majority just adopts chair seat to save space by the mode of vertically turning over to parallel to the ground, and desk there is no foldover design.This folding mode, for saving space, at utmost utilizes space, classroom to help little.Also have partially folded tables and chairs to be the modes adopting right-angled intersection support, this folding mode is not firmly with stable.And the utility model adopts brand-new folding mode, adopt slide bar, chute, slide rail, height that the cooperation in space realizes desk and chair folds, final class is folded to one block of thin almost plane plate, greatly can save space.And structure is simple, easy to operate, manual operation is convenient.Do not need to fold and fixed by locking device, avoid tables and chairs to be out of shape in use, ensure its stability.And the utility model also has several functions, as regulated height, can move freely, can area increased, be convenient to drawing demand etc.Present adjustment height desk and chair generally uses screw and nut to be coupled together desk top and the bottom, regulates during height and need use spanner or pliers, be inconvenient to operate also impracticable.The utility model adopts Spring lock catch to connect, simple and convenient, only need press Spring lock catch and adjustable.Existing desk cannot or be not easy to mobile mostly, and the employing of this utility model can screw out recoverable pulley and realize removable, is convenient to move freely desk and chair and use space, classroom flexibly.The utility model also contemplates in addition needs the demand of Major of charting, and application turnover panel increases usable floor area with the surface plate of parallel hinge links, and is furnished with book supporting board and is convenient to drawing, and this is the unique function that existing desk and chair does not have.
