Description

Height-adjustable table

The utility model is a Height-adjustable table, and one can be according to user's needs and the desk of regulated at will height.

Present used desk, though patterns such as desk workbench, specification are a lot, it highly all is uncontrollable, belongs to fixed high table.This people who makes different heights can not select and the most suitable height of own height in many cases.This mainly contains the adverse effect of two aspects to human body: the unbefitting height of table top of the first easily makes the people feel tired, and it two is to be unfavorable for the healthy of person of not bending over the desk for a long time, even may cause the pain and the morbidity of cervical spine.Fixed high table especially is unsuitable for children and uses.A people is from the kindergarten to the senior middle school, and height alters a great deal.Though adopt the desk of several different sizes at different learning phases, still can not satisfy the requirement that children's height changes.In family learning, family also inconvenience provides several specifications different desks for children, and children's physical growth critical stage of growing just during this, with the unbefitting desk height of height, cause incorrect learning posture, so that influence children's healthy development.

Task of the present utility model provides a kind of height-adjustable Height-adjustable table, and the realization height of table top can be regulated because of people's height, to overcome the above deficiency of being put forward the serviceability of fixed high table.

Task of the present utility model is finished as follows.Desktop and two four bar turntables link, and two four bars tangle and have cross bar to connect between frame.Tangle with regard to the frame with regard to one four bar, tangle two rod members that contact with ground of frame of four bars are rod member down, and two times rod member tangles in the crosspoint, and two rod members that link with desktop are upper lever, and the lower end of two upper lever tangles with the upper end of two times rod members respectively.Regulating part is set, makes the tangle rod member of frame and desktop of regulating part and four bars constitute stable triangle and link.Change the active length of regulating part, thereby the shape that can change four bar turntables is regulated height of table top.By regulating height of table top, make it to be complementary with the people of different heights, Height-adjustable table is particularly suited for children and uses, along with children's height changes, constantly regulate the desk surface height, make height of table top suitable with children's height, to guarantee the correct learning posture of children, be beneficial to the children's torso healthy development.In home education, a Height-adjustable table can accompany the preprimary child to growing up, and needn't change desk because of height changes, thereby receive bigger social benefit.

Below in conjunction with embodiment and accompanying drawing the utility model is elaborated.

Accompanying drawing is the longitudinal sectional drawing of a kind of concrete structure of the present utility model.

With reference to accompanying drawing: accompanying drawing has been showed the structure of Height-adjustable table one side, is cutd open the structure of a side, and is identical with the structure that accompanying drawing is showed, only provides explanation with regard to a side structure below.Desktop ［ 1 ］ links with connecting piece ［ 2 ］, ［ 18 ］, ［ 21 ］, if the desktop material require, connecting piece ［ 2 ］, ［ 18 ］, ［ 21 ］ also can be made into a long connecting piece.Connecting piece ［ 2 ］, ［ 18 ］ tangle by hinge ［ 3 ］, ［ 19 ］ and two regulating parts ［ 4 ］, ［ 17 ］ respectively, and connecting piece ［ 21 ］ tangles by twisted axis ［ 22 ］ and four bars by two upper lever ［ 20 ］, ［ 23 ］ and two times rod members ［ 8 ］, ［ 12 ］ formation frame that tangles.The upper end of two upper lever ［ 20 ］, ［ 23 ］ tangles by twisted axis ［ 22 ］ and connecting piece ［ 21 ］, its lower end tangles with two times rod members ［ 8 ］, ［ 12 ］ by hinge ［ 7 ］, ［ 13 ］ respectively, two times rod members ［ 8 ］ and ［ 12 ］ tangle by twisted axis ［ 11 ］, the two 4 bars frame that tangles links by cross bar ［ 9 ］, ［ 10 ］, ［ 14 ］, ［ 24 ］, and regulating part ［ 4 ］ and ［ 17 ］ are being located binding by sliding part and cross bar ［ 14 ］ and ［ 24 ］ in close upper lever ［ 20 ］, ［ 23 ］ respectively.Regulating part and desktop and two upper lever form stable triangle respectively and link.And then two upper lever and regulating part and desktop be whole and two times rod members formation triangles binding as one.When need are regulated height of table top, unclamping nut ［ 5 ］ and ［ 16 ］ sliding part ［ 6 ］ and ［ 15 ］ can slide up and down, the active length of regulating part changes, the distortion of four bar turntables, height of table top changes, when changing to, height of table top to a certain degree tightens nut ［ 5 ］ and ［ 16 ］, the setting of four bar turntables, and height of table top is fixed.Thereby receive the effect that height of table top can be regulated because of human needs.If special requirement is arranged, require desktop that certain gradient is arranged as drawing etc.Make the regulating part active length of front be shorter than the active length of back regulating part.Desktop can have certain gradient.

Claims (2)

1, a kind of desk of regulating height of table top is characterized in that: a, desktop link two four bars frame that tangles, and b, regulating part constitute stable triangle binding with the rod member and the desktop of four bars hinge knot frame,

2, Height-adjustable table according to claim 1 is characterized in that: the tangle upper end of upper lever and the desktop of frame of four bars links, and the lower end tangles with the upper end of following rod member, and following rod member tangles in the crosspoint.
