Description
Technical field
The utility model relates to office appliance field, the lifting desk surface especially using on desk.
Background technology
Along with social development, office's occupational disease is in rising trend.Existing desk height is all constant, or can customize height while manufacturing, once but its height or be difficult to change after being delivered for use.Clerk handles official business on the desk desktop in sustained height for a long time, very easily produces the occupational disease of waist, back, neck or shank.Applicant applied for without change with destroy former desktop in the situation that can lifting desktop, the lifting desk surface of the capable of regulating top height using on common desk.Lifting desk surface comprises desktop cover board and two groups of lifting supporting components, two groups of bottoms that are arranged on desktop cover board that lifting supporting component is parallel, and two groups of lifting supporting components drive desktop cover board to rise and fall the height adjusting that has realized desk tops.In actual production and use procedure, find that this lifting desk surface comes with some shortcomings, specifically desktop cover board lifting and while using desktop cover board easily shake, stationarity is slightly inadequate.
Summary of the invention
Goal of the invention of the present utility model is the not enough problem existing in order to overcome above-mentioned existing lifting desk surface, provides a kind of novel and reasonable structure, the lifting desk surface that stationarity is good.
In order to realize foregoing invention object, the utility model has adopted following technical scheme:
Lifting desk surface, comprises desktop cover board and two groups of lifting supporting components, two groups of bottoms that are arranged on desktop cover board that lifting supporting component is parallel, the inner side of every group of lifting supporting component is equipped with one group of bracing means, every group of bracing means forms by long fulcrum bar and short strut, short strut length is the 45%-55% of long fulcrum bar, desktop cover board is provided with straight line chute, the inner side of the position of straight line chute in lifting supporting component, straight line chute is provided with can be along the first bearing pin of its traveling priority, long fulcrum bar top connects on desktop cover board by the first bearing pin, the base of the bottom of long fulcrum bar and lifting supporting component bottom is hinged, short strut top is hinged on desktop cover board by the second bearing pin, short strut bottom is hinged on the midpoint of long fulcrum bar by the 3rd bearing pin, the position of short strut top on desktop cover board is between lifting supporting component top and long fulcrum bar top, described two groups of bracing means are symmetrical set along the mid point of desktop cover board.
As preferably, when desktop cover board rises state, bracing means is Y-shaped, has improved the stationarity of desktop cover board and lifting supporting component.
As preferably, the bottom of long fulcrum bar is hinged on the base of lifting supporting component bottom by the 4th bearing pin, the bottom of long fulcrum bar is rotated and is controlled the position of long fulcrum bar top on straight line chute by the bottom of long fulcrum bar, has improved the stationarity of desktop cover board and lifting supporting component.
As preferably, short strut length is half of long fulcrum bar.
Adopted the lifting desk surface of technique scheme, the inner side of every group of lifting supporting component is equipped with one group of bracing means, the bracing means consisting of long fulcrum bar and short strut opens with the rising of desktop cover board, decline with desktop cover board is shunk, realize interlock with lifting supporting component, improved the smoothness of desktop cover board and lifting supporting component.The position of short strut top on desktop cover board is between lifting supporting component top and long fulcrum bar top, short strut length is the 45%-55% of long fulcrum bar, can the most effectively strut and pack up desktop cover board, guarantee the smoothness of enough desktop cover boards and lifting supporting component simultaneously.The advantage of this lifting desk surface is novel and reasonable structure, not only when lifting, can prevent rocking of desktop cover board and lifting supporting component, and has also improved in use the stationarity of desktop cover board and lifting supporting component.
Accompanying drawing explanation
Fig. 1: the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
Lifting desk surface as shown in Figure 1, comprises desktop cover board 1 and the parallel bottom that is arranged on desktop cover board 1 of 2, two groups of lifting supporting components 2 of two groups of lifting supporting components.
The inner side of every group of lifting supporting component 2 is equipped with one group of bracing means 3, has the two groups of bracing means 3 in left and right.Every group of bracing means 3 forms by long fulcrum bar 32 and short strut 31.Desktop cover board 1 is provided with straight line chute 11, the inner side of the position of straight line chute 11 in lifting supporting component 2, straight line chute 11 is provided with can be along the first bearing pin 4 of its traveling priority, long fulcrum bar 32 tops connect on desktop cover board 1 by the first bearing pin 4, the base 21 of the bottom of long fulcrum bar 32 and lifting supporting component bottom is hinged, and specifically the bottom of long fulcrum bar 32 is hinged on the base 21 of lifting supporting component bottom by the 4th bearing pin 7.Short strut 31 tops are hinged on desktop cover board 1 by the second bearing pin 5, and short strut 31 bottoms are hinged on the midpoint of long fulcrum bar 32 by the 3rd bearing pin 6.The position of short strut 31 tops on desktop cover board 1 is between lifting supporting component 2 tops and long fulcrum bar 32 tops.Two groups of bracing means 3 are symmetrical set along the mid point of desktop cover board 1.When desktop cover board rises state, bracing means is Y-shaped, has improved the stationarity of desktop cover board 1.The bottom of long fulcrum bar 32 is rotated and is controlled the position of long fulcrum bar 32 tops on straight line chute 11, has improved the stationarity of desktop cover board.Short strut 31 length are half of long fulcrum bar 32, described length is the effective use length between each pin joint, specifically the length of the long fulcrum bar between the first bearing pin 4 and the 4th bearing pin 7 is 390mm, and between the second bearing pin 5 and the 3rd bearing pin, the length of 6 short strut is 195mm.
The bracing means consisting of long fulcrum bar 32 and short strut 31 opens with the rising of desktop cover board, lifting supporting component 2 rising jack-up desktop cover boards 1 specifically, move on straight line chute 11 laterally by the first bearing pin 4 on long fulcrum bar 32 tops, bracing means 3 is opened Y-shaped, owing to second bearing pin 5 on short strut 31 tops and the 4th bearing pin 7 positions of long fulcrum bar 32 bottoms can not movement can only rotating, therefore when lifting supporting component 2 rising jack-up desktop cover board 1, bracing means 3 can well be held desktop cover board 1 and lifting supporting component 2, prevent rocking of lifting desk surface.Bracing means 3 shrinks with the decline of desktop cover board 1, when specifically lifting supporting component 2 shrinks, desktop cover board 1 declines, masthead 32 ends of drawing money on credit move on straight line chute 11 to the inside by the first bearing pin 4, and bracing means 3 also shrinks with lifting supporting component 2 has realized interlock.
Between the 45%-55% that above-mentioned short strut 31 length are long fulcrum bars 32, all can.The advantage of above-mentioned lifting desk surface is that lifting stationarity can effectively prevent rocking of lifting desk surface well, without changing and destroying original desktop, especially being applicable to office uses, the desktop of the use differing heights that clerk is frequent, can regulate the state of shank, waist, back, neck and shoulder, prevent that it is for a long time in an angle and state and produce occupational disease.
