Description
Technical field
The invention belongs to furniture item technical field, particularly a kind of structure of office chair.
Background technology
Existing office chair major part to sit, cannot be lain only.Some seat system that can lie utilizes the layback of adjustable backrest to realize.But its shortcoming is: the seat system one, " only to sit, cannot lain " is unfavorable for the rest at people's noon.Two, the seat system center of gravity " utilizing the layback of adjustable backrest to realize " is fixed, non-adjustable, so the reclined by angle of backrest is limited.Chinese patent: 2009201318393 " a kind of seat systems of dual purposes of sitting and lying " can overcome the above problems, but its shortcoming is: sitting face does not tilt, comfortable not.
Summary of the invention
The object of the present invention is to provide one automatically to adjust center of gravity, inclination of the seat backrest is fixed adjustable, simultaneously the sitting face office chair of dual purposes of sitting and lying that can tilt.
For achieving the above object, technical solution of the present invention is: a kind of office chair of dual purposes of sitting and lying, as shown in Figure 1, Figure 2, Figure 3 shows, be made up of front foot pipe system, rear foot tube system, slide rail, alignment pin, pitch system, seat support, backrest, connection fabric, hinge tube and castor.Described front foot pipe system as shown in Figure 4, is made up of pin pipe, upper lateral tube, transverse tube and curved surface pipe.Wherein, described pin pipe bottom is closed, and has a screw hole, for connecting castor.Described upper lateral tube is a horizontal tube, welds together (or to be bent by same pipe with pin pipe form) with pin pipe.Upper lateral tube end face has four screw holes, for connecting pitch system.There is a king bolt hole upper lateral tube side, for connecting alignment pin.Upper lateral tube side also has three primary screw holes, for connecting sliding rail.Described transverse tube is a horizontal tube, for connecting pin pipe.In the middle of described curved surface pipe, high both sides are low, and both sides are by screw or be welded to connect upper lateral tube, and middle screw hole connects the hinge of hinge tube.After two described pin pipes and upper lateral tube are connected respectively and transverse tube and curved surface pipe by screw or be welded to connect.
Described rear foot tube system as shown in Figure 5, is made up of pin pipe, upper lateral tube, backing tube, transverse tube and hinge.Wherein, described pin pipe bottom is closed, and has a screw hole, for connecting castor.Described upper lateral tube is a horizontal tube, and weld together (or bend with pin pipe same pipe form) with pin pipe, there are three screw holes side, for connecting sliding rail.Described backing tube bottom and pin pipe weld together (or bend with pin pipe same pipe form), and two screw holes are arranged at top, by screw connection hinge.Described transverse tube is a horizontal tube, for connecting pin pipe.After two pin pipes of described rear foot tube system, upper lateral tube and backing tube are connected respectively and transverse tube weld together.Described hinge is universal component, outlines.It is while be connected with backing tube, and another side is connected with backrest.
