Description

The dual-purpose chair of a kind of office-recreational

Technical field:

The utility model relates to the chair technical field, more specifically to a kind of dual-purpose chair.

Background technology:

Office chair is one of office appliance of each company's indispensability now, but traditional office chair generally is the seat support of the first half can rotate and lifting with respect to the chair pin of the latter half, be merely able to adjust the height of chair, but its chair back can not adjust, have only a fixing angle.Yet when people handled official business tired need the rest, much people's custom was loosened upper body to layback, and the back angle can not be adjusted the demand that can not satisfy people's leisure, loosen.

So, a lot of such chairs have just appearred, its backrest constitutes by having certain flexible material or load onto elastic device on backrest, like this, when people habitually swing back upper body, back can form different inclination angles, and when people's health was sat straight, back can restore again under the effect of elastic force, such chair has satisfied people's needs to a certain extent, but it also has weak point: 1) its life-span shorter, after repeatedly using, the back restorability is poor, disappear until restorability, make backrest not reset, both influenced the use of chair, not attractive in appearance yet; 2) such back needs strong always effect thereon, in case this external force action disappears, chair will restore, and also needs when sitting down once more from new adjustment, uses inconvenient.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art part, provide a kind of office-recreational dual-purpose chair, it adopts the back hinged with handrail, air pressure rod and the adjusting device hinged with backrest also are installed, can allow back form different inclination angles simultaneously, can also be fixed on this incident angle, adjust simple, easy to use, the life-span is long, can realize the office, the leisure dual-purpose.

Technology solution of the present utility model is as follows:

The dual-purpose chair of a kind of office-recreational, comprise the chair pin, the chassis, seat and two handrails that are fixed on the seat, movable back is hinged by rotating shaft and described two handrails, described seat forms open slot, riveted and fixed has cover plate on the described seat, described cover plate lower surface is hinged with the connector that part is passed described open slot, the barred body matched in clearance of air pressure rod is installed in the described connector, the gas bar is hinged with the transition connecting plate that is fixed on the described movable back, and an end is hingedly mounted in the described connector, the side of the winding sheet that the other end links to each other with adjusting device contacts with the gas bar leading section of described air pressure rod.

The dual-purpose chair of described a kind of office-recreational, described adjusting device is propped up by control button, pulls wire and button and is configured to, the button bracket screw that control button is installed is fixed on the described seat, and described pulls wire one end is fixedlyed connected with control button, and the other end is connected with an end of described winding sheet.

The dual-purpose chair of described a kind of office-recreational is equipped with four chassis fixed blocks between described chassis and the seat.

The dual-purpose chair of described a kind of office-recreational is equipped with another air pressure rod between described chair pin and the chassis; The gas bar of described air pressure rod is fixedlyed connected with the chassis, and the regulating handle of controlling described air pressure rod lifting is installed on the described chassis.

The dual-purpose chair of described a kind of office-recreational, the open slot on the described seat communicates with the outer surface of the close movable back of described seat.

The beneficial effects of the utility model are:

Movable back is hinged by rotating shaft and described two handrails, air pressure rod and the adjusting device hinged with backrest also are installed, can allow the movable back of chair form different inclination angles simultaneously, movable back can also be fixed on this incident angle, adjust simple, easy to use, the life-span is long, can realize the office, the leisure dual-purpose.

The specific embodiment

Embodiment, see accompanyingdrawing 1 ~ 5, the dual-purpose chair of a kind of office-recreational, comprisechair pin 1,chassis 2,seat 3 and twohandrails 4 that are fixed on theseat 3,movable back 5 is hinged by rotatingshaft 6 and described twohandrails 4, describedseat 3 forms open slot 301, riveted and fixed hascover plate 7 on the describedseat 3, describedcover plate 7 lower surfaces are hinged with theconnector 9 that part is passed described open slot 301, barredbody 801 matched in clearance ofair pressure rod 8 are installed in the describedconnector 9,gas bar 802 is hinged with thetransition connecting plate 10 that is fixed on the describedmovable back 5, and an end is hingedly mounted in the describedconnector 9, the side of thewinding sheet 12 that the other end links to each other with adjustingdevice 11 contacts withgas bar 802 leading sections of describedair pressure rod 8.

Described adjustingdevice 11 is made ofcontrol button 1101,pulls wire 1102 andbutton support 1103,button support 1103 screws thatcontrol button 1101 is installed are fixed on the describedseat 3, described pulls wire 1,102 one ends are fixedlyed connected withcontrol button 1101, and the other end is connected with an end of describedwinding sheet 12.

Four chassis fixedblocks 13 are installed between describedchassis 2 and theseat 3.

Anotherair pressure rod 14 is installed between describedchair pin 1 and thechassis 2; Thegas bar 1401 of describedair pressure rod 14 is fixedlyed connected withchassis 2, and the regulatinghandle 15 of controlling describedair pressure rod 14 liftings is installed on the describedchassis 2.

Open slot 301 on the describedseat 3 communicates with the outer surface of the closemovable back 5 of describedseat 3.

Operation principle: in the time of use, when the user need be againstmovable back 5 reclining backward,press control button 1101 and drivepulls wire 1102 pullingwinding sheets 12, and then thegas bar 802 ofair pressure rod 8 compressed inbarred body 801, the user exerts oneself on movable back 5 a little simultaneously,movable back 5 can rotate around the rotating shaft on the handrail 46, determine the angle of reclining backward according to thegas bar 802 flexible strokes ofair pressure rod 8, when the angle of adjusting was suitable, the user unclampscontrol button 1101 can reach needed effect.And when the user needsmovable back 5 to recall to original angle, as long aspress control button 1101, under the effect ofair pressure rod 8 compressed airs,gas bar 802 stretches out, do not apply any active force this moment onmovable back 5,movable back 5 is resetted, easily convenient again.And control the height thatair pressure rod 14 can also be adjusted theseat 3 that is connected withchassis 2 by regulatinghandle 15.
