The utility model content
The purpose of this utility model is to provide a kind of and adjusting rod is reduced rock, the rack leg stability height of chair, rational in infrastructure, easy fracture not, the low adjusting amplitude of seat plate hight is bigger, and the experiment chair that can prevent dust fungi-proofing again, it is applicable to places such as school, hospital, shop.
The purpose of this utility model is achieved by the following technical programs, but is not limited only to for example:
The utility model provides a kind of and regulates chair just with adjusting rod, and it mainly is made up of seat plate, adjusting rod, adjusting rod sheath, central sleeve, rack leg, step ring etc.It is characterized in that: the seat plate vertically connects support by adjusting rod and is " T " font, and the lifting of seat plate is carried out height by adjusting rod and regulated; Central authorities' sleeve is a vertical cylinder of going up lower through-hole, plays the mobile jib structure function, and fixing and collected adjusting rod of chair; Rack leg top vertically is connected with central sleeve cluster, and the oblique fork in bottom is contacted to earth, and is connected by annulus binding, and this annulus double as step ring uses; Rack leg is seen from the front and is resembled " A " word shape; The adjusting rod part of being exposed between seat plate and the mobile jib sleeve is entangled by a telescopic cylindric sheath of going up lower through-hole, has dustproof anti-pollution.
A kind of improvement project of the present utility model is as follows: described adjusting rod is a screw rod, and chair reaches the purpose of seat plate lifting by the rotation of screw rod.Screw rod is collected in the central sleeve, is provided with plastic plug at the center hub tube bottom and seals the mouth of pipe, prevents spilling for the lubricated machine oil of screw rod of the inside.Upper end and stage casing in the sleeve respectively are fixed with a swivel nut, are used for cover and catch screw rod, make screw rod have two to be the cover contact of a determining deviation in sleeve, reach the purpose that screw rod is not easy to rock.The stop washer of an external diameter greater than screw rod is equipped with in screw rod bottom, the screw rod bottom revolved be restricted when being raised to the stage casing swivel nut and can not break away from central sleeve.The oblique fork of foot of described " A " font leg support is contacted to earth, and foot's mouth of pipe is equipped with anti-skidding plastic plug.
The utility model may further be: described adjusting rod is a vapour bar and is collected in the supporting with it central sleeve, thereby is combined as one group of vapour lever apparatus, reaches the purpose of seat plate lifting by the pressure of vapour bar.
The utility model also may further be: described adjusting rod and mobile jib sleeve can extend lengthening downwards, reach to make the bigger purpose of seat plate lifting travel; Described step ring can have two layers up and down, and same and " A " font leg support bottom binding binding, and purpose is that seat plate step ring height when differing heights is also different, makes things convenient for user's demand.
A kind of improvement project of the present utility model also can be as follows: in foot's mouth of pipe of described " A " font leg support, can overlap ground engaging stabiliser wheel, Convenient chair moves on ground.
The utlity model has following beneficial effect: strengthened that leg support flexing resistance, chair stability are good, seat plate heave amplitude big, have the fungi-proofing function of sealing and dustproof thereby the center of gravity of leg support is higher, handsome in appearance.
