Description
Technical field：
Pneumatic type field of office furniture is the utility model is related to, specifically a kind of Pneumatic lifting desktop.
Background technology：
In recent years, with the fast development and popularization of computer technology, more and more people are frequently using computer
Many slight illness are also accumulated from the same time, not only visual impairment, and bring cervical spondylosis, lumbar vertebra disease etc. under accumulating over a long period；In order to subtract
These few ailing generations, it is noted that striking a proper balance between work and rest, still further aspect pays attention to keeping posture of correctly handling official business one side people.Electricity
The sub- equipment such as main auxiliary facility of computer, notebook, IPAD this kind of product is exactly desk and chair, the daily long-time of user
The office that is seated result in the invasion and attack of occupational disease；
For this reason, occurring the desk that can be lifted on the market recently, the alternately office joy of people's stance and sitting posture is met
Happy demand；But existing liftable desktop mainly has two classes, one kind is the liftable desk by manual folding table leg, usually this
The crowd that class same table only has a kind of height to be directed to has significant limitations, in addition first manually must fold out table angle when in use
It is very inconvenient electronic equipment is put up use again；Another kind of same table can realize different height lifting and locking up and down
Function, but in such same table, often also still higher allows client to be to lift forever when being seated office even if being preferably minimized
Head goes down or can influence the health such as cervical vertebra, lumbar vertebrae for a long time, for a long time user can be allowed to abandon using.
In 201520728687.0 self-powered platform of the patent No., including between undersetting, upper bracket, upper bracket and undersetting
X-type elevating mechanism and elastic component, which can make the X-type elevating mechanism on undersetting both sides be synchronized with the movement, and can add
The intensity of strong self-powered platform, but still have the defects of certain：1st, the movable lifting mechanism of X-type structure needs to install guide rail
And carriage, trouble is made, improves cost, aesthetics reduces；2nd, elastic component is respectively equipped with the movable device of both sides,
The height of elastic component makes lifting desk surface can not keep certain and puts down more or less there are certain difference during artificial installation elastic component
Weighing apparatus degree, and after the precision of elastic component does not adjust when dispatching from the factory, there are desktop both sides always during the use of user afterwards
The situation of height.Therefore, if a kind of gas for reducing cost, improving aesthetics, strengthening lifting intensity and the degree of balance can be provided
Dynamic formula lifting desk surface, it is definitely imperative.
The content of the invention：
Deficiency the purpose of this utility model is to overcome more than, there is provided one kind reduces cost, improves aesthetics, strengthens
Lift the Pneumatic lifting desktop of intensity and the degree of balance.
