Description
Technical field
The present invention relates to a kind of swivel chair, especially a kind of safe and reliable swivel chair.
Background technology
In recent years, either office space or family's occasion, more and more people are using swivel chair as the primary choosing of configuration
It selects.Swivel chair relative to traditional chair itself distinct feature is that three cushion, support shaft and pedestal parts, cushion portion can be divided into
Above gravity is transferred to pedestal only by support shaft.This structure has led to swivel chair and is not so good as traditional chair in terms of mechanics
Son is stablized, and stretches one's body or the problem of while leaning to one side to pick up thing is easy to happen rollover when people are sitting on swivel chair.Existing swivel chair lacks
The alarm set of weary rollover causes user to be easy because rollover problem is injured, and safety is relatively low.In addition, the universal wheel of existing swivel chair
Connection between pedestal is all rigid, and the cushion performance of chair is only realized by the softness of cushion, lacks anti-vibration
Ability causes the comfort of chair poor.More commonly, the universal wheel of present swivel chair in use for some time, wheel shaft quilt
Such as hair, rubbish sundries blocks, and causes wheel shaft rotation motionless, the flexibility of swivel chair is made to decline.Therefore, there is peace in existing swivel chair
Full property and the poor problem of comfort, and swivel chair universal wheel does not have antiwind ability, the flexibility of swivel chair is poor.
Invention content
The object of the present invention is to provide a kind of safe and reliable swivel chairs.The present invention has safety and comfort good
Feature, and the universal wheel of the present invention has antiwind ability, overall flexibility good.
Technical scheme of the present invention：A kind of safe and reliable swivel chair, including be arranged from top to bottom cushion, support shaft, bottom
Universal wheel on seat and pedestal, the universal wheel includes installation axle, and installation axle is arranged with lower gasket, spring successively from top to bottom
And Upper gasket, lower gasket are fixed on the mounting shaft, Upper gasket is fixed on the base, and the junction of Upper gasket and pedestal is equipped with pressure
Force snesor；The support shaft is equipped with control device, and control device is connected with the pressure sensor, control device
It is also associated with alarm set；Universal wheel further includes axle support, and axle support is equipped with wheel shaft, and wheel shaft both ends are equipped with runner；Institute
The runner stated is equipped with cricoid flange and annular groove towards the side of axle support, and gear is evenly distributed in the flat sidewall of annular groove
Piece；The axle support close to the end face of runner be equipped with the matched cladding flange of flange, cladding flange radially
Between flange and catch.
In a kind of safe and reliable swivel chair above-mentioned, the alarm set is vibrating device, and vibrating device setting is being sat
In pad.
Compared with prior art, then the present invention is passed through by pressure sensor is arranged in the junction of each universal wheel
Control device compares the maximum value of pressure and the difference of minimum value, when the difference just indicates that swivel chair has rollover beyond preset range
Danger, control device drive alarm set to remind user dangerous, cause user injured to avoid turning on one's side with this.Meanwhile each
The junction of universal wheel and pedestal is equipped with spring, and thus the present invention has good anti-vibration performance, and chair comfort property is made to obtain
Greatly improve.On the other hand, the present invention makes wheel shaft by the cladding flange of axle support and the flange fit structure of runner
Outside being not exposed to, also just it is not easy to be wound by sundries.Catch is additionally provided on runner, catch is evenly distributed on cladding flange outer sides.
Therefore, it can be blocked by catch sandwiching object in universal wheel, the sundries being wrapped on catch is cut off by pocket knife to be cleared up.
Further, alarm set of the invention is vibrating device, is reminded by way of vibration and does not both interfere with him
People, and user can be made in time and perceive danger signal with will not omitting ground, there is preferable prompting effect.
To sum up, the present invention has the characteristics that safety and comfort are good, and the universal wheel of the present invention has antiwind energy
Power, overall flexibility are good.In addition, the rollover warning of the present invention reminds effect good.

Specific implementation mode
With reference to embodiment, the invention will be further described, but is not intended as the foundation limited the present invention.
Embodiment：A kind of safe and reliable swivel chair constitutes cushion as shown in Figures 1 to 5, including being arranged from top to bottom
400, the universal wheel 100 on support shaft 300, pedestal 200 and pedestal, the universal wheel 100 include installation axle 101, installation axle
101 are arranged with lower gasket 102, spring 103 and Upper gasket 104 successively from top to bottom, and lower gasket 102 is fixed in installation axle 101,
Upper gasket 104 is fixed on pedestal 200, and the junction of Upper gasket 104 and pedestal 200 is equipped with pressure sensor 201；Described
Support shaft 300 is equipped with control device 301, and control device 301 is connected with the pressure sensor 201, control device 301
It is also associated with alarm set 401；Universal wheel further includes axle support 110, and axle support 110 is equipped with wheel shaft 120, wheel shaft 120
Both ends are equipped with runner 130；The runner 130 is equipped with cricoid flange 131 and annular groove 132 towards the side of axle support 110,
Catch 133 is evenly distributed in the flat sidewall of annular groove 132；The axle support 110 is equipped with close to the end face of runner 130
With 131 matched cladding flange 111 of flange, cladding flange 111 is between flange 131 and catch 133 radially.
The alarm set 401 is vibrating device, and vibrating device is arranged in cushion 400.
Operation principle：By being arranged lower gasket 102,103 and of spring in installation axle 101 between universal wheel 100 and pedestal 200
The structure of Upper gasket 104 connects.This structure has good anti-vibration performance.The junction of Upper gasket 104 and pedestal 200 is equipped with
The pressure of pressure sensor 201, each universal wheel is transmitted to control device 301 by pressure sensor.Control device 301 is preferred
Ground uses embedded scm, control device 301 to be used for the stress of more each universal wheel.It should be evident that working as swivel chair
When rollover, the wheel pressure at rollover point is naturally larger than the pressure of wheel on the other side.Therefore, when the pressure of universal wheel maximum
When difference between value and minimum value is more than predetermined value, show that swivel chair has the danger of rollover.At this point, control device 301 is by carrying
Device 401 of waking up reminds user, avoids turning on one's side.
Alarm set 401 is preferably by vibrating device, and vibration frequency is 1-8Hz, vibration ratio of the human body to the range
It is more sensitive.It is reminded by way of vibration and does not only interfere with other people, but also user can be made in time and perceive dangerous letter with will not omitting ground
Number, there is preferable prompting effect.
The projection of cladding flange 111 and flange 131 and cladding flange 111 and catch 133 in the axial direction all has overlapping
It partly (coats flange 111 and covers flange 131, the covering cladding of catch 133 flange 111), thus wheel shaft 120 is not exposed to
Outside, also just it is not easy to be wound by sundries.Catch 133 is evenly distributed on one " annulus ", even if universal wheel is involved in sundries, sundries
Also it can only be wrapped on catch 133, pocket knife, which is stretched between two catch 133 to cut off sundries, can clear up sundries, make universal wheel
It restores to the original state.
