Description
Technical field
The present invention relates to life chair art, more particularly to a kind of handrail and Height Adjustable Convenient type chair.
Background technology
Chair is people's family expenses and all indispensable furniture of handling official business, and without chair, the basic activity of the mankind can all become
It is very not convenient, but existing chair, which can not more meet user, more and more to be required.Although existing chair is adjusted automatically
Section height has a lot, but the handrail of chair can not be voluntarily is controlled, handle adjusting it is handling nor very high, this
When a kind of Convenient type chair of invention design can overcome the seated person to visit in use before body the need for arm support,
The regulation of height of seat can be taken into account.
The content of the invention
The present invention provides a kind of Convenient type chair in view of the deficiencies of the prior art, and the present invention can overcome prior art
Weak point, by handrail slide rail guide rail stretching motion so that when alignment pin is by oppressive force, locating pin spring by
Extruding, is retracted in handrail slide rail with alignment pin, then handrail slide rail passes through guide rail under the advance component effect of arm oppressive force
Bearing travels forward, and meets when being visited before seated person body, there is provided facility forward together with arm for handrail.
The technical scheme is that a kind of Convenient type chair, including seat and the chair back, the chair back arranged on left and right sides is symmetrical
It is provided with adjustable handrail；The adjustable handrail includes handrail slide rail, guide rail, guide rail bearing, positioning hole, alignment pin, alignment pin bullet
Spring, the handrail slide rail is socketed on the guide rail by the guide rail bearing, and the positioning hole linear distribution is in the handrail
On the inside of slide rail, the alignment pin is fixed on the inside of the guide rail by the locating pin spring.
The positioning hole number is more than 1, and the aperture of the positioning hole is less than the plunger diameter of the alignment pin, the positioning
Alignment pin described in Kong Nengyu coordinates under the elastic force effect that the locating pin spring is provided.
The alignment pin is fixed in the front end on the inside of the guide rail by the locating pin spring, the alignment pin along its
Axial-movement, the movement locus of the handrail slide rail is on the bearing of trend of the guide rail.
Also include an arrangement for adjusting height, the arrangement for adjusting height is arranged between the seat and ground, described
Arrangement for adjusting height includes lifting cylinder, retaining ring and connection wire rod, and the connection wire rod and the seat are affixed, the lifting
Cylinder is used cooperatively by the connection wire rod with the retaining ring.
The connection wire rod there are small end face of the quantity more than 1 and large end face portion, each small end face and
The large end face portion constitutes a working face.
The cross-sectional area of the small end facial (4-3-1) is less than the large end face portion, and the external diameter of the lifting cylinder is more than
Internal diameter under the diameter of the large end face cross section product, the retaining ring locking state is accumulated less than the large end face cross section
Diameter, the internal diameter under the retaining ring releasing orientation is more than the diameter that the large end face cross section is accumulated, the adjustable handrail
The seat is fixed in by support bar, the chair bottom can be rotated, the guide rail connects for plug.
In summary, the invention has the advantages that：
1st, the stretching motion of handrail slide rail is passed through so that when alignment pin is by oppressive force, locating pin spring is squeezed, with fixed
In the pin retraction handrail slide rail of position, then handrail slide rail is transported forward under the advance component effect of arm oppressive force by guide rail bearing
It is dynamic, meet when being visited before seated person body, there is provided facility forward together with arm for handrail.
2nd, chair is controlled to reach required height by arrangement for adjusting height, it is very convenient.
Below by drawings and examples, technical scheme is described in further detail.
