Abstract
The utility model relates to a foldable and height-variable domestic student desk, which belongs to domestic desks for students. A desktop (6) is supported by symmetrical desk frames (1) through a height-variable frame (3) and a positioning frame (5). The height of the desktop (6) is changed through the match of two screws on a vertical pipe (7) on the desk frame (1) and even number positioning holes on the height-variable frame (3). The desktop can turn over through the match of an eccentric shaft (9) which is fixed on the upper end of the height-variable frame and positioning holes which are distributed on a circular arc shape on a positioning plate. When a sliding pin (2) drives two supporting rods of the desk frame slide up and down along a long slide way on the vertical pipe, two legs of the desk frame (1) can be folded or unfolded.
Description
The utility model belongs to student's family expenses desk.
Mostly the desk that present student learns usefulness at home is fixed, can not carry out lifting because of student's stature height, can not more can not fold according to student's the angle of inclination that posture is adjusted desktop of writing.
The purpose of this utility model provides the folding family expenses student's desk of a kind of liftable, and this desk is simple in structure, and is easy to use, as long as adjust the relative position between table frame standpipe (7) and the crane (3), just desktop (6) can be carried out lifting.Adjust the mutual alignment of fixing each locating hole of location-plate on the table with eccentric shaft (9), just can make the desktop various angle of overturning.Slide up and down in chute by sliding pin (2), table frame (1) can be realized drawing in or strutting.When eccentric shaft is fixed in the end locating hole of location-plate (5), can make desktop (6) edge-on.
The utility model is by table frame (1), and crane (3) and desktop switching mechanism are formed.Desktop (6) is supported by symmetrical table frame (1), about table frame two leg bottoms connect by two cross bars respectively, left and right sides crane (3) top is connected by a cross bar.Table frame (1) two leg upper orifice is ∪ shape groove on one side, and the another side mouth of pipe is made flat, is socketed into a garden arc mutually, and and standpipe (7) upper end be riveted together, bottom one-tenth splayed, footing is equipped with rubber case.Monolateral axial microscler chute is arranged at standpipe (7) bottom, mounting screw hole perpendicular to the chute direction is respectively arranged at middle part and top, table two supports in frame lower end, and an end is riveted on a frame two legs, the other end is fixed together by sliding pin (2), and is fixed in the microscler chute by sliding pin end boss.10 equidistant locating holes are arranged on the crane (3), link together,, just can realize the lifting of desktop (6) when crane (3) cooperates with screw (4) with its five groups of holes respectively with two screw and nuts (4) and standpipe (7).There are the axis hole of a fixed eccentric shaft (9) and the rivet hole of a stationary positioned plate (5) in crane (3) upper end.The desktop switching mechanism is screwed in the desktop bottom on one side by square location-plate (5), another right-angle side of location-plate becomes isosceles triangle perpendicular to desktop, drift angle becomes the garden arc, the locating hole that has five garden arcs to distribute on the plate, interconnect the rivet hole that the centre has one and crane (3) upper end to be riveted together between each hole.Eccentric shaft (9) can be fixed on desktop a certain angle by the locating hole on the location-plate (5), from desktop (6) end face, can be docile and obedient clockwise or upset counterclockwise, when the eccentric direction of eccentric shaft (9) to the left or to the right the time, desktop (6) can be in level, be tilted to the left 5 °, 45 ° 50 °, and the location is realized in 85 ° and 85 ° of six positions that are tilted to the right.Cylindricality eccentric shaft (9) one ends in garden are eccentric elongated garden posts, and head has cotter-pin hold, and back cushion sheet and split pin are fixed on spring (8) on the eccentric shaft, and the other end is the garden shape handle of band tapering.
The utility model compared with prior art, it has makes desktop lifting, flip angle and folding function.To adapt to different height students' use, also can adjust the desktop angle with different purposes simultaneously according to student's the posture of writing.The utility model is easy to use, as long as sliding pin (2) is slided up and down along the sliding pin groove, just table frame two legs can be folded or struts.
The utility model can also be used to doing easel or music easel.
