Abstract

The utility model discloses a chair which comprises two front support legs, two rear support legs, a chair seat and a backrest. Screw rods are arranged at the top end parts of the front support legs and the rear support legs; two penetration holes and two front threaded holes are formed on the chair seat, and the screw rods of the front support legs are in threaded connection with the front threaded holes; and two rear threaded holes are formed at the bottom end of the backrest, and the screw rods of the rear support legs penetrate through the penetration holes and are in threaded connection with the rear threaded holes. Because the support legs, the chair seat and the backrest are in threaded connection, so that the chair occupies small space before the threaded connection, which facilitates package and transportation.

Description

A kind of chair

Technical field

The utility model relates to a kind of chair, particularly relates to a kind of chair with backrest.

Background technology

The chair of existing band backrest, it comprises a seat support, four supporting legs and a backrest.This four supporting legs top is welded on the bottom surface of seat support, and this backrest bottom is welded on the end face of seat support, thereby makes this seat support, supporting leg and backrest be fixed together.Because between supporting leg and the seat support, all adopts welding or other not detachable fixed connection structure between seat support and the backrest, therefore packing inconvenience, carrying are inconvenient.

The utility model content

The utility model provides a kind of chair, and it has overcome the existing packing inconvenience of background technology chair, the inconvenient deficiency of carrying.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of chair, it comprises:

Two front leg struts, its top ends is set as screw rod;

Two rear support legs, its top ends is set as screw rod;

One seat support, it offers two through holes and two preceding thread holes, the screw rod of this front leg strut preceding thread hole that is spirally connected; And

One backrest, its bottom are provided with two rear thread holes, and the screw rod of this rear support leg passes through hole and is spirally connected the rear thread hole.

In the preferred embodiment of the present utility model, this through hole is set to mate the screw flight hole of rear support leg.

In the preferred embodiment of the present utility model, this seat support comprises a chair frame and a seat board that is installed on the chair frame, this chair frame comprises the rear transverse rod of a front rail, a parallel front rail and the intermediate bar between the cross bar of at least one affixed front and back, and stretch out outside the seat board at the both ends of this rear transverse rod; Two above-mentioned through holes are separately positioned on the both ends of rear transverse rod.

In the preferred embodiment of the present utility model, two above-mentioned preceding thread holes are separately positioned on the both ends of front rail.

In the preferred embodiment of the present utility model, this seat board comprises a panel, and this faceplate perimeter extends into bound edge downwards, offers two breach on this bound edge; This two breach is sheathed and be resisted against rear transverse rod, the bottom surface of above-mentioned chair frame support panel.

In the preferred embodiment of the present utility model, this bound edge surrounds front rail and intermediate bar, and the end of this rear transverse rod is passed breach and stretched out outside the bound edge.

In the preferred embodiment of the present utility model, this backrest comprises the backboard of two back support bar and affixed two back support bar; Two above-mentioned rear thread holes are separately positioned on the bottom of two back support bar.

The technical program is compared with background technology: 1, because the employing of the syndeton between supporting leg, seat support and the backrest is threaded, and it is little to take up room before therefore being spirally connected, be convenient to packing, carrying.2, because the screw rod of rear support leg passes the seat support backrest that is spirally connected again, therefore a screw rod can be realized having avoided fixedly connected between a rear support leg, seat support and the backrest at seat support two groups of screwed holes (one group of coupling rear support leg, another group coupling backrest) being set.3, because the through hole screw flight hole that is set to mate rear support leg, so fixedly connected solid and reliable between supporting leg, seat support and the backrest.4, this bound edge surrounds front rail and intermediate bar, so the chair appearance looks elegant.5, owing to offer two breach on this bound edge, therefore provide the bit space that allows that stretches out outside the bound edge for the rear transverse rod end.6, because through hole is arranged on the end of rear transverse rod, therefore need not to be provided with screwed hole on panel, panel is attractive in appearance, intensity is high.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 has illustrated the schematic perspective view of the chair of a preferred embodiment.

Fig. 2 has illustrated the perspective exploded view of the chair of a preferred embodiment.

The specific embodiment

Please refer to Fig. 1 and Fig. 2, a kind of chair, it comprises two front leg struts 100, two rear support legs 200, a seat support 300 and a backrest 400.

The top ends of the top ends of this front leg strut 100, two rear support legs 200 all is set to screw rod.

This seat support 300 comprises that a chair frame and is installed in the seat board 310 on the chair frame.This chair frame comprises the rear transverse rod 330 of a front rail 320, one parallel front rail 320 and the intermediate bar 340 between two parallel, the affixed front and back cross bar 330,330, these rear transverse rod 330 both ends are stretched out outside the intermediate bar 340 and are formed extension, and this front rail 320 does not stretch out outside the intermediate bar 340.These front rail 320 left and right end portions all are provided with the preceding thread hole 350 of the screw rod of a coupling front leg strut, all be provided with a through hole that runs through up and down 360 on two extensions of this rear transverse rod 330, the hole is set to mate the screw flight hole of rear support leg within this through hole 360.

This seat board 310 comprises a panel, and this faceplate perimeter extends into bound edge 370 downwards, offers two breach 380 on this bound edge 370, and these breach 380 end faces flush with the panel bottom surface.

This two breach 380 is sheathed respectively and be resisted against two extensions of rear transverse rod 330, and the bottom supporting of this panel is at the end face of chair frame.And: this front rail 320, two intermediate bars 340 and rear transverse rod 330 (major part) are positioned at (increase aesthetic property) within the bound edge 370, and two extensions of this rear transverse rod 330 pass two breach 380 respectively and stretch out outside the bound edge 370.

This backrest 400 comprises the backboard of two back support bar 410 and affixed two back support bar 410, and the bottom surface of this back support bar 410 offers rear thread hole 411.

The screw rod of the above-mentioned front leg strut 100 preceding thread hole 350 of seat support 300 that is spirally connected is so that form a fixed connection structure between front leg strut 100 and the seat support 300; The screw rod of above-mentioned rear support leg 200 through hole 360 that the passes seat support 300 rear thread hole 411 of backrest 400 that is spirally connected again that is spirally connected is so that form a fixed connection structure between rear support leg 200, seat support 300 and the backrest 400.This fixed connection structure has also played the effect of fixed base plate 310 and chair frame.After fixing, these front leg strut 100 bottom surfaces and rear support leg 200 bottom surfaces flush.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
