Description

The height of table top adjusting device

Technical field

The utility model relates to a kind of height of table top adjusting device, refers to a kind of simple in structurely especially, and can arbitrarily adjust the table body of desktop high and low position, and it is also quite laborsaving when adjust rising.

Background technology

In today that information is maked rapid progress, have only constantly and enrich, just can avoid own is eliminated by the epoch mighty torrent, and form good reading habit, nothing more than being a kind of good method, so-called " a workman wants to do his work well must first sharpen his tools " again, a good desk, use not only comfortablely, more help to promote mood in study, and then reach best reading effect; But because structures such as general common desk, desk, more its desktop is established and is fixed form, so for the user that height differs and be not suitable for, especially just child at developmental school age, its height is constantly to change, so more need the table body structure of adjustable lifting.

But, though as seen desk or the desk of adjusting height of table top can be provided now on the market, but most of members all need to establish by leading of stay cord, cooperate the shake-up of push switch to control that driving cylinder is flexible just can be reached, so its design is all too complicated, price is relatively costly, and can't popularize in general family.

Therefore, if can develop a kind of table body of adjusting the desktop high and low position, allow this physical efficiency more suit measures to different persons, this body does not need again to lead to be established stay cord and has been used push switch, just can reach the purpose of adjusting lifting, with the complexity and the cost of effective its structure of reduction, price is relatively cheap, buying and can be fit to general family, is the problem place of the applicant institute desire improvement.

So the applicant thinks and the idea of utility model, satisfy with for many years experience and designed, through inquiring into and study sampling test in many ways, and repeatedly revise improvement, be to release the utility model.

The utility model content

The purpose of this utility model is to provide a kind of height of table top adjusting device, it includes: a base, one driving cylinder and a bracing frame, wherein, base is the foot lever support ground with both sides, laterally be provided with a lower connecting rod between foot lever, one end of driving cylinder can be fixed on this lower connecting rod, then each up is extended with a main strut at the rear, this two main strut is slightly inclined backward, and be provided with an auxiliary table surface between the top, driving cylinder is the pneumatic cylinder of clear way valve, so not needing to utilize the switching of magnetic valve to control it advances, exhaust, the expansion link that is set in the Master cylinder body is outwards initiatively stretched out when normality, bracing frame is laterally to be provided with a upper connecting rod within it between side by two support arms to form, this two support arms back segment top respectively is provided with a projection, then be pivoted with a desktop between the place ahead, this desktop can be by the control of cutting of angular adjustment apparatus, change its height of steeving, or directly down be positioned on the projection by touching, two support arm rears respectively are provided with the wide wide collar in main strut periphery footpath that is slightly larger than in week footpath in again, respectively be provided with sliding-proof pad in the collar, make when bracing frame is set on the main strut together with desktop utilizes collar, can leaning forward naturally by desktop weight, driving collar stings to fixing on main strut with oblique state, and because two arm rooms also are provided with a upper connecting rod, so can make the other end of driving cylinder be fixed on this upper connecting rod, with this, can access a kind of height of table top adjusting device.

The utility model beneficial effect against existing technologies:

1, the height of table top adjusting device that provides of the utility model, utilize the transfer of bracing frame and desktop center of gravity, the driving cylinder that cooperates full-open type air pressure, to not need to lay stay cord and push switch, and also can reach the purpose of control desktop lifting, be with, this design can effectively reduce the complexity of its structure, cost and price can significantly be repaiied down again, and then allow this body can be fit to general family to buy, to popularize in person on the market.

2, the height of table top adjusting device that provides of the utility model, because the expansion link of driving cylinder can be initiatively protruding, so set upright when bracing frame and to allow collar not sting when fixing on main strut, can utilize this expansion link to stretch out the auxiliary of strength, and initiatively the whole bracing frame of pushing tow makes progress together with desktop, and it will be laborsaving relatively when adjusting.
