Description
Technical field
Improved the present invention relates to a kind of seat, refer in particular to a kind of cooperation by involute plate and holddown spring, locked lifting
Axle；By the cooperation of involute plate and button, the lifting height of lifting shaft is controlled with meet different Man's Demands and is easy to regulation
The chair of height.
Background technology
Chair is one of conventional furniture of living at home, and chair can be used when having dinner, learn or chatting.And dining table, book
The height of table or tea table is skimble-scamble, and before these desks, the chair for sitting single height can feel many inconveniences, additionally,
For the chair of the desk with different height of different height had both sunk money or had taken limited furniture space；Therefore, we research and develop
A kind of chair for being easy to adjust height that can be switched fast chair height, so as to reducing waste of resource and space.
The content of the invention
To solve the above problems, the present invention provides a kind of cooperation by involute plate and holddown spring, locked lifting shaft；
By the cooperation of involute plate and button, the lifting height of lifting shaft is controlled with meet different Man's Demands and is easy to regulation height
Chair.
The technical solution adopted for the present invention to solve the technical problems is：A kind of chair for being easy to adjust height, the bottom of comprising
Disk seat；Lifting shaft is provided with the subbase；Hard cushion is provided with the lifting shaft；The subbase outer surface of upper sets
It is equipped with hollow rectangular preiection；Rotatable double involute plate is provided with the rectangular preiection；Set on the involute plate
Having makes involute plate realize locked holddown spring with lifting shaft；The afterbody of the involute plate intersects, and infall is provided with
Through the button of rectangular preiection.
Preferably, a fixing axle is provided with the rectangular preiection；Be provided with each described fixing axle it is rotatable gradually
Burst at the seams plate；Be provided with holddown spring on the involute plate inner surface, and the holddown spring other end fix to be arranged on rectangle convex
On rising；The involute plate makes outer surface be brought into close contact with lifting shaft to realize locked, prevent under the elastic force effect of holddown spring
Lifting shaft is slided；The afterbody of the involute plate intersects and can mutually slide；The afterbody infall of the involute plate is provided with
Through the button of rectangular preiection；During work:Button is pressed, the cooperation with fixing axle is pushed by making the afterbody of involute plate, will
Involute plate is separated with lifting shaft, so as to cause lifting shaft to rise in the presence of the recovery elastic force of compression spring, drives hard seat
Pad rises；Release button, then by the locked lifting shaft of double involute plate, hard cushion stops rising.
Preferably, the subbase the inside is provided with the compression spring of vertical placement；The compression spring top is provided with
Lifting shaft；The compression spring can rise lifting shaft in the presence of elastic force is recovered.
Preferably, it is provided with hard cushion on the lifting shaft；The ventilative chair back is provided with behind the hard cushion.

Specific embodiment
To make technical scheme become more apparent, specific embodiment is made into one to the present invention below in conjunction with the accompanying drawings
Step explanation.
If Fig. 1-3 is the chair for being easy to adjust height of the present invention, comprising subbase 1；The inside of the subbase 1 sets
It is equipped with the compression spring 2 of vertical placement；The top of the compression spring 2 is provided with lifting shaft 3；The compression spring 2 can be extensive
Lifting shaft 3 is set to increase in the presence of multiple elastic force；Hard cushion 4 is provided with the lifting shaft 3；The hard cushion 4 is provided with below
The ventilative chair back 5；The chair back 5 is set to arc, can mitigate pain in the back, vertebra pain etc.；The outer surface of upper of the subbase 1 sets
It is equipped with hollow rectangular preiection 6；2 fixing axles are provided with the rectangular preiection 6（Do not mark）；Each described fixing axle（Not
Mark）On be provided with rotatable involute plate 7；Holddown spring 8 is provided with the inner surface of involute plate 7, and compresses bullet
What the other end of spring 8 was fixed is arranged on rectangular preiection 6；The involute plate 7 makes outer surface under the elastic force effect of holddown spring 8
It is brought into close contact with lifting shaft 3 and realizes locked, prevents lifting shaft 3 from sliding；The afterbody of the involute plate 7 intersects and can mutually slide
It is dynamic；The afterbody infall of the involute plate 7 is provided through the button 9 of rectangular preiection 6.
During work:Button 9 is pressed, the cooperation with fixing axle is pushed by making the afterbody of involute plate 7, by involute plate 7
Separated with lifting shaft 3, so as to cause lifting shaft 3 to rise in the presence of the recovery elastic force of compression spring 2, driven on hard cushion 4
Rise；Release button 9, then by the locked lifting shaft 3 of double involute plate 7, hard cushion 4 stops rising.
Detailed operation state description is as follows:
（1）During propradation：Pin button 9 to unlock, push the afterbody of involute plate 7, tilt the front end of involute plate 7, so that
Compress holddown spring 8；Now involute plate 7 and lifting shaft 3 are separated, and compression spring 2 is made institute in the presence of elastic force is recovered
Lifting shaft 3 is stated to rise；The simple structure of the seat of the regulation height, it is easy to use.
（2）During locking state：Release button 9, the afterbody of release involute plate 7 is acted in the recovery elastic force of holddown spring 8
Under make involute plate 7 turn round and lifting shaft 3 contact, play locking function, now the lifting shaft 3 can not rise.
