Description
The utility model relates to the furniture class, the adjustable adjustable desk of height of table top that especially a kind of student uses.
Desk is the requisite classroom of student articles for use, what use in a large number at present is that highly fixing desktop is level or is with the fixedly desk of the gradient, and for a school, the used desk of primary grades and higher grade pupil substantially all is with a kind of specification, the desk of horizontal table top can not keep eyes parallel with written sight line, easily make eyes impaired, highly non-adjustable desk desktop for the students of the junior years is too high, can not guarantee that eyes are apart from the enough distances of desktop, for the higher grade pupil, desktop is too low again, during reading, cause hunchback when especially writing easily, desktop is too high all to be unfavorable for cultivating the correct writing posture of student with crossing to hang down.Someone has designed a kind of adjustable for height desk, and it is respectively to add a height adjustment mechanism on the table leg of both sides, reaches the purpose of regulating table height.It is asynchronous that the shortcoming of this structure desk is that the governor motion on both sides is regulated, and perhaps wants two hands to operate simultaneously or operation successively, therefore complicated operation not only, and also the desktop after regulating is easy to generate and influence is used.
The purpose of this utility model is to design a kind of adjustable for height desk, and the people that can be fit to differing heights and all ages and classes uses.Designed desk is simple in structure, and the inclination of desktop can not take place after the adjusting in adjusting and easy to use.
Adjustable desk of the present utility model is made up of desk body and adjustable support.The desk body comprises desktop, several drawers, and adjustable support comprises lower pillar stand, undersetting.Between last lower pillar stand height adjustment mechanism is arranged.Upper pillar stand is fixedlyed connected with desktop at the central part of desktop.For the desktop that makes desk has the different gradients, the desktop of design is by fixedly desktop and active desktop are formed, two desktops are hinged in a side, active desktop can turn to from the position that overlaps with fixing desktop and the fixing vertical position of desktop, and positioner also is housed between two desktops.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the adjustable desk of the utility model design.
Accompanying drawing 2 is a kind of height adjustment mechanisms of the utility model design.
Accompanying drawing 3 is another kind of height adjustment mechanisms of the utility model design.
Accompanying drawing 4 is another height adjustment mechanism of the utility model design.
Accompanying drawing 5.6 is various positioners between the desktop of the utility model design.
Accompanying drawing 7 is the A-A cutaway views among Fig. 5.
Desk body in Fig. 1 desk is made up of desktop and several drawers.Desktop by active desktop 12 and fixedly desktop 11 form, two desktops are hinged at drawer's frontal, so active desktop can form different gradient and make desktop parallel with people's eyes.There is positioner appropriate location at two desktops, a kind of mode wherein is the mode that adopts among Fig. 5, the arc 1 that the band saw tooth is promptly arranged on the middle position of active desktop, fixedly on the desktop corresponding opening 2 is being arranged, side at opening has groove 3, promote arc and make desktop after required angle, make sawtooth card in the groove of opening, can make desktop be fixed on this gradient.The positioner of Fig. 6 is the arc 4 that the belt length hole is housed in active desktop one side, pass slotted hole on the arc at the bolt 5 that the band wing nut is arranged on the fixed head, unscrew nut and can regulate the gradient of active desktop, during to the gradient that needs, fastening nut can be located.Also can adopt other detent mechanism,, can make active desktop be level and a certain gradient two states as the hook-type adjustable plate being housed in the fixing central appropriate location of desktop.
Adjustable support in Fig. 1 desk is made up of upper and lower column 13,14 and undersetting 15.Undersetting can be designed to the cross fork-shaped.Between last lower pillar stand height adjustment mechanism is housed.Height adjustment mechanism can adopt jack type＜Fig. 2 〉, screw fastening-type＜Fig. 3〉and packing fastening-type＜Fig. 4 〉.The jack type height adjustment mechanism is in the lower end of upper pillar stand some holes 6 to be arranged at a certain distance, a hole is arranged on lower pillar stand, when needing to regulate height, only need make a certain hole of the hole aligning upper pillar stand of lower pillar stand, insert latch 7 then and can make desk be fixed on a certain height.Screw fastening-type height adjustment mechanism is the skewed slot that there is certain-length the lower end of upper pillar stand, lower pillar stand is enclosed within the outside of upper pillar stand, on its appropriate location, top screwed hole and screw are arranged, tighten screw and can fix upper pillar stand, when need regulating height, unclamp screw and upper pillar stand is moved on to behind the desired height trip bolt again can locate.Packing fastening-type arrangement for adjusting height comprises internal and external casing 8,9 and the packing 10 with threaded engagement.The top and the upper pillar stand of outer tube 9 are slidingly matched, the bottom of inner sleeve 8 and lower pillar stand secure fit, packing has wedge shape section, is arranged in internal and external casing and the formed space of last lower pillar stand, rotary sleeve pipe 9 when needing to regulate height, outer tube is risen, and at this moment the power of holding tightly of packing reduces, so upper pillar stand can move up and down along the inwall of packing, when being adjusted to desired height, rightabout turns outer tube, and outer tube is descended until making packing hold upper pillar stand tightly, reaches the location purpose.
