Abstract
The utility model relates to a chair back and a seat controller, comprising a chair back and a chair seat which are pivoted together each other. The chair back is pivoted with a cylinder barrel of a pneumatic pump. A cylinder axis of the pneumatic pump is combined with a fixing seat which is arranged on the chair seat. The fixing seat is provided with a rod component for hand operation. A sliding rail device is arranged between the chair seat and a base seat arranged below the chair seat. The pneumatic pump works by operating the rod component. The slope angle of the chair back and the chair seat can be adjusted, and the chair seat can maintain proper gravity centre position to hardly incline by matching with the supporting function of the sliding rail device.
Description
The utility model is a kind of chair back and seat support control device of seat, particularly a kind of angle of inclination of adjusting the chair back and seat support, the control device that is difficult for toppling over so that the center of gravity of seat remains on the appropriate location.
Known office all is provided with the chair back at seat substantially with seat, and the chair back can be fixing with seat or the pivot joint mode is provided with; Wherein, the chair back that is provided with in the pivot joint mode can be adjusted its angle of inclination voluntarily according to user's comfort level needs.Yet, traditional structure is when adjusting chair back angle of inclination, its seat still remains on the stationary water level state, thereby when the chair back is to tilt, the center of gravity of whole seat promptly moves toward the rear, and the chair back more tilts, and its center of gravity is more near the rear, so when being against the chair back to lie than big strength, the user is easy to toward the rear overturning, and comparatively dangerous in the use; And traditional pivot seat is being provided with most connecting rods below the seat support and between the base, in order to increasing its intensity, but makes its structure comparatively complicated.
Main purpose of the present utility model is to provide a kind of chair back and seat support control device of seat, it can adjust the angle of inclination of the chair back and seat support simultaneously, can also make the center of gravity of whole seat remain on the appropriate location and avoid overturning, it is convenient that it is braked, easy and smooth and easy.
The utility model is the improvement that the existing deficiency of control device at above-mentioned conventional adjustable chair back angle of inclination is carried out.The chair back of seat provided by the utility model and seat support control device, it has that than the chair back and the seat support that articulate, this chair back is pivoted with the cylinder barrel of a pulsometer, the cylinder axle of pulsometer is then in conjunction with a holder, and make holder be located at seat support, holder is provided with and can supplies manual rod member, the cylinder axle head extends a protuberance, promote protuberance by the operant activity rod member, but the master cylinder axle is relative with cylinder barrel flexible, seat support and be located between the base of its below and be provided with railroad, its be sheathed on an outer rail by rail in one and relatively linear slide formed, outer rail is fixedly arranged on base, and interior rail is hubbed at the seat support below; Utilize pulsometer to be located between the chair back and the seat support, and the railroad between base and seat support when making pulsometer work by the operation rod member, can be adjusted the angle of inclination of the chair back and seat support, and cooperate the supporting role of railroad, make seat keep suitable position of centre of gravity and be difficult for toppling over.And convenience is braked and is made control device easier and smooth and easy.
The utility model also is provided with a slotted eye at holder, rod member passes the end that makes rod member behind the slotted eye again holder that is pivoted, rod member can be spurred or loosen the protuberance of being located at the cylinder shaft end by pulling rod member, protuberance can be controlled the flow direction of pulsometer internal hydraulic pressure oil, thereby the master cylinder axle is flexible with respect to cylinder barrel, when promoting protuberance, can make pulsometer work, and then adjust the angle of inclination of the chair back and seat support when the operation rod member.
Advantage of the present utility model and function will more be known about after being described further by drawings and Examples.

Embodiment
As shown in Figure 1 to Figure 3, the chair back of seat provided by the utility model and seat support control device, be on a base 25, to be provided with a vertical sleeve 251, sleeve 251 is equipped with a lifting shaft, the lifting shaft upper end sets firmly a pedestal 252, seat 252 tops are in conjunction with a seat support 22, and the rear end of seat support 22 is pivoted with a chair back 21.The design's control device is to be provided with railroad 24 below this seat support 22 and between the pedestal 252, the preferred embodiment of railroad 24 is to cooperate rail 241 in an outer rail, and be provided with plural ball (not shown) between interior rail 241 and the outer rail and make interior rail 241 can with outer rail linear slide relatively; Outer rail is fixed in pedestal 252 with welding manner, and the end of interior rail 241 then is hubbed at seat support 22 belows, thereby seat support 22 is had oblique support force up.Be provided with a pulsometer 1 independently in addition, its cylinder barrel is articulated in the chair back 21 near limit, lower end one side by a pivot 23, its cylinder axle is combined with a holder 12 that is Contraband shape, and make this holder 12 be connected to the side of seat support 22, Contraband shape holder 12 tops are provided with a slotted eye 121, in addition a rod member 13 is passed the upper bottom surface (being articulated section 131) of again lower ending pivot of rod member 13 being located at holder 12 behind this slotted eye 121, and the cylinder axle of pulsometer 1 extends in the holder 12, its cylinder axle head extends a protuberance 11, promote protuberance and can control the pulsometer 1 gas inside flow direction, the master cylinder axle is flexible with the reciprocating motion that promotes its internal piston; Because the structure and the technology of these protuberance 11 control gas flows are known technology, non-emphasis of the present utility model is so no longer carefully state.
Utilize the design's drawing device, when pulling rod member 13, and when making rod member 13 promote protuberances 11, protuberance 11 can be controlled the valve of pulsometer 1 inside and the cylinder shaft extension is gone out, this moment, pulsometer 1 had the strength that seat support 22 is pushed ahead, make the chair back 21 to recede, seat support 22 also rises toward updip a little simultaneously, the weight of whole seat is remained near the center, thereby the user is in that lie when being against the chair back 21 not can overturning, and cooperate railroad 24 to be supported in the strength of seat support 22 belows, can make whole seat more firm; When stopping the promotion to protuberance 11 when decontroling rod member 13, can stop the updip of seat support 22 and recede (as shown in Figure 3) of the chair back 11; When oppositely pulling rod member 13, then protuberance 11 utilizations are located at the gas pressure (reaction force) in the air pressure pump shaft and outwards stretch out automatically, thereby the valve direction that has changed pulsometer 1 inside turns to compressed air, and then make in the cylinder axle retraction cylinder barrel, make the chair back 21 and seat support 22 all can original in the past direction reset and adjust angle (as shown in Figure 2) forward; Therefore, more convenient, the laborsaving and safety of its operation, and have stronger practicality.
The above is only in order to explain preferred embodiment of the present utility model; be not to be to any formal restriction of the utility model; therefore, all have in that identical creation spirit is following do relevant any modification of the present utility model or change, all should be included in the scope of the utility model protection.
