Sliding block 133a is hinged.The piston rod of second hydraulic cylinder 133 pushes assister bar 152 to move by the first sliding block 133a, pushes indirectly
Bracket 151 is unfolded.
First sliding rail 154 can limit the motion path and the direction of motion of the first sliding block 133a, prevent the first sliding block 133a
The direction of motion shift, guarantee the stability that is integrally driven of the second linkage portion 150.
Further, elastic component 153 is spring, and elastic component 153 is sheathed on the first sliding rail 154, one end of elastic component 153 with
First sliding block 133a connection, separate second liquid that the first sliding rail 154 is connected to far from first one end sliding block 133a of elastic component 153
133 one end of cylinder pressure.
Elastic component 153 is for compressing second hydraulic cylinder 133, when multi-function ofice chair 100 is converted to " seat by the state of " bed "
When the state of chair ", by pulling rocking bar 144c come rotary spacing bar 144b, and then make the first rack gear 144a and the second rack gear 142a
Separation releases the lock state of multi-function ofice chair 100；At this point, the elastic force due to elastic component 153 acts on, elastic component 153 is pushed
First sliding block 133a drives assister bar 152 to make bracket indirectly towards the Slideslip close to second hydraulic cylinder 133, the first sliding block 133a
151 pack up；Liquid medium in second hydraulic cylinder 133 has been also forced into first hydraulic cylinder 132, due to first hydraulic cylinder 132
Piston rod is moved towards far from cylinder barrel side, and the piston rod of first hydraulic cylinder 132 drives driving portion 121 by the first linkage portion 140,
So that backrest 120 is rotated relative to seat board 110, multi-function ofice chair 100 reverts to the state of " seat "；Finally by rotary spacing
Bar 144b relocks drive block 142, and multi-function ofice chair 100 is just locked into the state of " seat ".
Whole process user only needs operation locating part 144, other conversions are completed by linked manner, province easy to operate
When, without other redundancy steps, is conducive to that user is made to rapidly enter resting state, improves rest quality.
It should be noted that elastic component 153 can also be elastic bellows in the other embodiments of the utility model.
But it is not limited only to this.
Further, Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 are please referred to, multi-function ofice chair 100 is also
Including foot pad 160 and third linkage portion 170, seat board 110 has the second sliding rail 111, and foot pad 160 is slidingly disposed at the second sliding rail
111.Third linkage portion 170 includes limit connecting rod 171, lever 172 and second connecting rod 173, and one end of limit connecting rod 171, which has, to be slided
There is the second sliding block 121a, the second sliding block 121a to be slidably received in sliding slot 171a for slot 171a, driving portion 121, lever 172
One end and seat board 110 are hinged, and one end of the other end and second connecting rod 173 of lever 172 is hinged, the separate thick stick of second connecting rod 173
172 one end of bar and foot pad 160 are hinged, and 121 one end of separate driving portion and the lever 172 for limiting connecting rod 171 are hinged.
When backrest 120 is rotated relative to seat board 110, driving portion 121 drives drive block 142 will by first connecting rod 141
The cylinder barrel of the liquid medium indentation second hydraulic cylinder 133 of first hydraulic cylinder 132, at the same time, the second sliding block of driving portion 121
121a slides into 121 one end of separate driving portion of sliding slot 171a, and the second sliding block 121a pushes limit connecting rod 171, limits connecting rod 171
Lever 172 is driven to rotate around the rotational axis line of lever 172, then second connecting rod 173 is moved with lever 172, and then second connects
Bar 173 pushes foot pad 160 to slide in the second sliding rail 111, and foot pad 160 in seat board 110 by skidding off.When 100 turns of multi-function ofice chair
When being changed to the state of " bed ", foot pad 160 is fully slid out.
When multi-function ofice chair 100 is converted to the state of " seat " by the state of " bed ", the second sliding block of driving portion 121
121a slides into 121 one end of close driving portion of sliding slot 171a, and the second sliding block 121a drives limit connecting rod 171 towards driving portion 121
Movement, limit 171 pull lever 172 of connecting rod, lever 172 pull second connecting rod 173, second connecting rod 173 then by foot pad 160 again
It retracts in seat board 110.
Foot pad 160 is used for feet when user's rest and uses, and improves rest comfort level.And foot pad 160 skidding off and withdrew
Journey is linked with driving portion 121 by third linkage portion 170 realize completely, and time saving using simplicity without other operations, comfort level is high.
It should be noted that in the present embodiment, in the entire state conversion process of multi-function ofice chair 100, second
The angle of connecting rod 173 and foot pad 160 is consistently less than 90 degree.Preferably, second connecting rod 173 and the angle of foot pad 160 are small always
In 80 degree.Third linkage portion 170 also can be set it is multiple, to enhance third linkage portion 170 to the thrust and pulling force of foot pad 160.
Further, multi-function ofice chair 100 further includes the headrest 180 and push rod 190, and backrest 120 has third sliding rail
122, the headrest 180 is slidingly disposed at third sliding rail 122, and one end of push rod 190 is connect with the first sliding block 133a, push rod 190
The other end is connect with the headrest 180.Push rod 190 is arranged in parallel with the first sliding rail 154.
In the state procedure that multi-function ofice chair 100 is converted to " bed " by the state of " seat ", the first edge sliding block 133a
First sliding rail 154 is moved towards the side far from second hydraulic cylinder 133, and the first sliding block 133a pushes push rod 190, and push rod 190 then will
The headrest 180 is released.After multi-function ofice chair 100 is switched to the use state of " bed ", the headrest 180 is fully slid out.
In the state procedure that multi-function ofice chair 100 is converted to " seat " by the state of " bed ", the first edge sliding block 133a
First sliding rail 154 is moved towards the side close to second hydraulic cylinder 133, and the first sliding block 133a pulls push rod 190, and push rod 190 then will
