Specific embodiment

It is described in further detail with reference to the accompanying drawing and by specific embodiment to invention, following embodiment is descriptive , it is not restrictive protection scope of the present invention.

Embodiment

A kind of office chair, referring to Fig.1 shown in-Fig. 9, including chair body, chair body includes cushion 1 and is located at cushion The support portion 2 of 1 lower end, further includes the backrest of 1 rear side of handrail and cushion of 1 two sides of cushion, and support portion 2 is bent by a steel pipe It forming, a supporting plate is provided with below cushion 1, supporting plate is welded on steel pipe upper end, and sliding is accommodated with leg rest mechanism in support portion 2, The driving portion convenient for pushing the leg rest mechanism is provided between support portion 2 and leg rest mechanism, between driving portion and support portion 2 also It is provided with the first position-limit mechanism of limit leg rest mechanism.

Referring to Fig.1 shown in, leg rest mechanism include with support portion 2 sliding cooperation two pieces of support plates 3 being parallel to each other and Be set between support plate 3 can relative support plate 3 rise or fall or inclined Fang Jiao mechanism, on the outer wall of support plate 3 End is vertically convexly equipped with the sliding block 11 for extending to 3 both ends of support plate, the T shape of the preferred major part of the cross sectional shape of the sliding block 11 outwardly outward Or it is trapezoidal, the opposite side of support portion 2 is provided with the sliding slot 302 slid for sliding block 11.

Wherein, the second through slot 201 being connected to sliding slot 302 is provided on 2 outer wall of support portion, referring to shown in Fig. 2, Fig. 6, Driving mechanism include when leg rest mechanism stretch out when in sliding block 11 outside the outside projection in one end of cushion 1 to the second through slot 201 Slide bar 303 and the push rod 305 of 303 end of slide bar rotation setting, the side in the one end of slide bar 303 far from sliding block 11 are convex vertically Equipped with a postive stop baffle 304, the push rod 305 may be reversed 180 °

First position-limit mechanism is included on slide bar 303 referring to shown in Fig. 2, Fig. 3 to the extension of the both ends of the second through slot 201 Limit inserted link 301, the opposite both ends of limit inserted link 301 are arranged to tip outwardly pyramidal, the both ends of through slot be provided with The jack that limit 301 interference of inserted link plugs.

When using leg rest mechanism, only push rod 305 need to be flipped up 180 ° touch postive stop baffle 304 after, push forward Push rod 305 can push forward entire leg rest mechanism, be limited until being inserted into limit inserted link 301 in jack.

Fang Jiao mechanism is leaned on including the bottom plate 4 that is set between 3 downside inner wall of support plate, 4 upper end of bottom plate referring to shown in Fig. 2 Respectively arranged first air bag 12 and the second air bag 13 and it is located at the first air bag 12 and the second air bag at the both ends of nearly support plate 3 The toe board 5 of 13 upper ends, when leg rest mechanism is stretched out, toe board 5 has been set up close to one end of cushion 1 perpendicular to toe board 5 baffler 7, the setting of baffler 7 avoid foot from skidding off toe board 5, are respectively provided on the first air bag 12 and the second air bag 13 There are a unidirectional charge valve and air vent 15.

In order to facilitate deflation, a bleeder pipe 9 is connected on air vent 15, referring to Fig.1, shown in Fig. 5, Fig. 5, in support plate A mounting hole is provided on 3, bleeder pipe 9 is fixed in mounting hole far from one end of air vent 15, bleeder pipe 9 can interference be plugged in It is bonded in mounting hole in mounting hole or by adhesive glue, it is that the silica gel adhesive glue that viscous force reaches carries out that brand, which can be selected, in adhesive glue Bonding, is arranged closure 10 that is openable or closing the air vent 15 far from one end of air vent 15 in bleeder pipe 9.By above-mentioned Setting, without bending to deflate when deflation, need to only remove the closure 10 in support plate 3 just can be carried out deflation.

In order to facilitate inflation, one is provided on unidirectional charge valve to mechanism of qi structure, shown referring to Fig.1, this be to mechanism of qi structure One inflator pump, inflator pump can be selected hand and pinch inflator pump, drawing and pulling type inflator pump, pedal inflator pump or electric inflating pump, in conjunction with making Hand-pinch type inflator pump can be selected in valence and convenience, when inflation, two inflator pumps of pinching is only needed to be able to the first air bag 12 and second inflation in air bag 13, the adjusting of 5 angle of toe board, general first air bag may be implemented by the height of two air bags 12 fill a large amount of gas, and 13 aeration quantity of the second air bag is less than or equal to the first air bag 12, and toe board 5 is made to be sloped downwardly setting in interior, Referring to shown in Fig. 7-Fig. 8.

Since the leg of some people is longer, and while liking being seated, stretches leg, therefore, 4 relative support plate 3 of bottom plate can front and back sliding Adjustment is provided with the first through slot 306 extended to 3 both ends of support plate, bottom referring to shown in Fig. 5, Fig. 8 and Fig. 9 in support plate 3 The both ends evagination of plate 4 has the slide plate 19 extended to outside the first through slot 306.It is also set up between slide plate 19 and support plate 3 limited The second position-limit mechanism that position bottom plate 4 slides, the second position-limit mechanism includes the upper and lower side in the second through slot 201 along the second through slot It the spaced threaded hole 16 of 201 length directions, the vertically disposed limit plate 17 in the one end of slide plate 19 far from bottom plate 4 and passes through The fastening bolt 18 fastened after limit plate 17 with threaded hole 16.Bottom plate 4 can be made to move certain position further along by the setting, Until user's leg extension comfortable position.

When winter it is cold, foot's blood, which does not recycle, is easy long pernio, therefore, a foot-warming board 6 is further fixed on toe board 5, Referring to shown in Fig. 2, Fig. 4, which can be selected carbon crystal foot-warming board 6, and the carbon crystal foot-warming board 6 that brand is intelligence promise can be selected, this is warm It is also staggeredly equipped with anti-skid chequer 601 on sole 6, may be implemented to heat sole by foot-warming board 6, achieve the effect that warm foot.

The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications It should be regarded as protection scope of the present invention.
