Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in attached drawing 1 to attached drawing 5, a kind of chair back angle adjustment mechanism, including the whole L-shaped chair back 7 and the chair back 7
The chair back connector 6 that transverse bottom is fixedly connected, the 7 transverse bottom front end of the chair back are connected with seat base 4, further include
Control-rod 1, gas bar 2, the gentle bar bolt 5 of connector 3 in Qian type；The control-rod 1 includes the L-shaped body of rod 12 and is set to bar
The gas bar jacking block 11 of 12 Basolateral of body；The gas bar 2 include cylinder 22, set on 22 end of cylinder chair back connecting pin 21, from
The telescopic rod 23 that extends in cylinder 22 is in set on the regulation button 24 on 23 top of telescopic rod, with what 23 top of telescopic rod was connect
The active connection 25 of Qian type and jack 251 set on 25 Qian type structure two sides of active connection；The bottom of the connector 3 with
4 bottom of seat base is fixedly connected, and the side of the 3 Qian type structure of connector is equipped with notch 31, the 3 Qian type structure of connector
The other side be equipped with control bar jack 32, be additionally provided with pin hole, gas bar top on the inside of the notch 31 and control bar jack 32
Block 11 is installed by notch 31 in connector 3 and 12 bottom of body of rod insertion control bar jack 32, the chair back connecting pin 21 with
Chair back connector 6 is flexibly connected, and the 25 Qian type structure of active connection is set in 3 Qian type structure of connector, gas bar top
Block 11 is set in 25 Qian type structure of active connection and contacts with regulation button 24, and the gas bar bolt 5 sequentially passes through connector 3
Pin hole and jack 251 be flexibly connected active connection 25 with connector 3 and limit the activity of gas bar jacking block 11.
Working principle: user carries control-rod 1 upwards, and gas bar jacking block 11 generates pressure to regulation button 24, in gas bar 2
Portion's air pressure is released, and telescopic rod 23 is stretched out from cylinder 22, since seat base 4 is flexibly connected with 7 transverse bottom front end of the chair back,
And chair back connector 6 is fixedly connected with 7 transverse bottom of the chair back, chair back connecting pin 21 is flexibly connected with chair back connector 6, telescopic rod
23 with stretchings of cylinder 22 lead to the angle of 7 upper end of the chair back, and user is stretched using back to the application pressure of the chair back 7 at this time forward
The compression of contracting bar 23 retracts into cylinder 22, while the chair back 7 being adjusted to suitable angle, unclamps again control-rod 1, completes chair at this time
The angular adjustment of back 7.
