Abstract
A kind of office chair back of the elastic torsion device of band, include back frame, upper end rotating bar, support end and elastic force torsion device composition, the back frame is fixed with upper end rotating bar by the screwed hole of back frame and the both sides external part of rotating bar by screw, the elastic force torsion device includes the elastic shaft comprising a supports main shaft and four offer torsion, upper end rotating bar has a main shaft with the support end center of circle simultaneously, it is connected upper end rotating bar and support end, four elastic shafts are fixed on support end, in upper end rotating bar have to circular hole and arc hole position.The utility model realizes the chair back by using simple mechanism on traditional office chair back and reverses certain angle along axis bilateral so that office chair more conforms to ergonomics, drastically increases comfort level when user uses seat.The utility model use range is wide, can use on the chair in a variety of places, such as office space, the adjustable seat on the vehicles such as aircraft, high ferro, can be used for family, personal use.
Description
Technical field
The utility model belongs to office appliance and field of furniture, and in particular to is used for office space to one kind or rests at home
Deng office chair on use, the torsion that can pass through elastic shaft produces the chair back of elastic force.
Background technology
Currently, because life and work rhythm are accelerated, the office hours for the crowd that handles official business generally is more than eight hours, while more next
More people selects various vehicles trips, and people spend the substantial amounts of time on chair, due to sitting, along with making
With unsound seat and incorrect sitting posture, cause a large amount of crowds in various degree with diseases such as cervical spondylopathy, protrusion of lumber intervertebral disc
Disease, with the development of science and technology the improvement of people's living standards, healthy living is increasingly becoming emphasis of concern, and health is comfortable
Office chair increasingly important is seemed to office crowd.But traditional office chair back can provide for the shoulder back of the body of people in the market
Bounce and few, the utility model realizes office chair back using easy structure can be bonded the shoulder back of the body in twist process
And produce the function of elastic force.
The content of the invention
For the drawbacks described above and problem of prior art, technical problem to be solved in the utility model is to provide a kind of band
The office chair back that elastic force reverses, its is simple in construction, easy to operate, and adaptability is good.
In order to achieve the above object, the utility model provides following technical scheme：
A kind of chair back that function is reversed with elastic force, it is characterised in that：Including back frame, upper end rotating bar, support end and bullet
Power torsion device forms, and the back frame passes through spiral shell with upper end rotating bar by the screwed hole of back frame and the both sides external part of rotating bar
Nail is fixed, and the elastic force torsion device includes the elastic shaft comprising a supports main shaft and four offer torsion, while upper end
Rotating bar has a main shaft with the support end center of circle, is connected upper end rotating bar and support end, four elastic shafts are fixed on support end,
Upper end rotating bar have to circular hole and arc hole position.
In above-mentioned technical proposal, the elastic force torsion device is installed on chair back back frame back, is installed along back axis.
In above-mentioned technical proposal, the chair back can be by back frame applying power, so that upper end rotating bar can be with it
Turned an angle centered on the center of circle.
In above-mentioned technical proposal, the core for providing chair back torsion occurs relative from upper end rotating bar with support end
Torque caused by its four elastic shafts torsions during rotation.
In above-mentioned technical proposal, four elastic shafts are symmetrically installed, and keep fixed with support end.
In above-mentioned technical proposal, the hole position coordinated in the upper end rotating bar with four elastic shafts is two circular holes and two
Arcuate socket, circular port is symmetrical on the forward sight reference plane of rotating bar, and the right side that arcuate socket is located at rotating bar is symmetrical regarding reference plane.
It is of the present utility model that the flexible regulation of chair back cushion is realized by the mechanism of routine on the office chair backrest of system,
So that office chair more conforms to ergonomics, effectively alleviate adaptability problem of the different crowd for office chair bustle.This practicality
New use range is wide, can use on the chair of various places, such as office space, on the vehicles such as aircraft, high ferro
Tables and chairs, it can be used for family, personal use.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of the utility model protection.
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, as a kind of chair back that function is reversed with elastic force shown in embodiment, by carrying on the back
Frame, upper end rotating bar, support end and elastic force torsion device composition.Back frame is with upper end rotating bar by the screwed hole of back frame with turning
The both sides external part of lever is fixed by screw, and elastic force torsion device is included comprising a supports main shaft and four offer torsion
Elastic shaft, elastic force torsion device is installed on chair back back frame back, is installed along back axis, while upper end rotating bar and support
There is a main shaft in the end center of circle, is connected upper end rotating bar and support end, four elastic shafts are fixed on support end, rotating bar has in upper end
Corresponding circular hole and arc hole position, the support end other end are connected by bolt with chair bottom., will for ease of understanding in Fig. 4
Upper end rotating bar is pulled open with support end, and in actual use, the 5 metal shaft axis of elasticities fixed with support end are fully-inserted
