Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment.
Refering to Fig. 1 to Fig. 4, one embodiment of the height adjustable seat unit of the utility model, a base is included
The back cushion unit 30 of chair cushion unit 20, one of unit 10, one and an elastic buffer unit 40.
The base unit 10 is in hollow tube-shape including a chassis member 11 and one and upwardly extended by the chassis member 11
Riser part 12, the chassis member 11 have the several chair legs 111 radially arranged and several are respectively arranged in the end of the chair leg 111
Hold the roller 112 of bottom.The riser part 12 extends along an axis L.
The chair cushion unit 20 includes the 21, peaces of sleeve part for being in hollow tube-shape and being sheathed on outside the riser part 12
Chair cushion 22, one loaded on the bottom of sleeve part 21 is installed on the bottom of sleeve part 21 and positioned at the lower Quick Release of the side of chair cushion 22
Group 23 and a handle 24 for being installed on the top of sleeve part 21.Coordinate ginseng Fig. 5, the sleeve part 21 has one and levels off to bottom
Perforate 211, be divided into for a pair the both sides of perforate 211 212, one, pivot ear be arranged at top shrouding 213 and one be located at
The articulated section 214 of the lower section of shrouding 213, the lower Quick Release group 23 is articulated in the pivot ear 212, and can be stretched at this with one and open
Lower stopper portion 231 in hole 211, operating the lower Quick Release group 23 can make the sleeve part 21 adjust or produce relative to the riser part 12
It is fixed.
Coordinating ginseng Fig. 6, the back cushion unit 30 can adjust and be installed on the top of sleeve part 21 of the chair cushion unit 20, and including
One beam ring part for being sheathed on the sleeve part 21 31, one is installed on the upper Quick Release group 32 of the beam ring part 31 and one is installed on this
The back cushion 33 of beam ring part 31, operating Quick Release group 32 on this can make the beam ring part 31 adjust or produce admittedly relative to the sleeve part 21
It is fixed.
The elastic buffer unit 40 is along axis L extensions and is installed on inside the riser part 12 and the sleeve part 21, and wraps
Include one and be articulated in the base unit 10 and level off to the bottom bar part 41, one of the chassis member 11 and be articulated in the top of the sleeve part 21

Between elastic buffer body 43, the elastic buffer body 43 can be gases at high pressure, hydraulic oil, or gases at high pressure, hydraulic oil and spring
Complex.
Again as shown in figure 4, showing that the chair cushion 22 is located at minimum state, now, the elastic buffer unit 40 has minimum
Length.
As shown in Figure 7 and coordinate ginseng Fig. 5, when operator pulls the lower Quick Release group 23, and make the lower stopper portion 231 relative to
The riser part 12 produces pine oil, and the sleeve part 21 can adjust relative to the riser part 12, due to the sleeve part 21 and the riser part
The effect that is relatively fixed between 12 is released from, using the elastic buffer body 43 of the elastic buffer unit 40 contained return release bullet
Power, the sleeve part 21 can be made to be shifted upwards relative to the riser part 12, meanwhile, the sleeve part 21 also drive the chair cushion 22 and this lean on
Single pad member 30 produces remote relative to the base unit 10.When adjusting to required height, operator pulls the lower Quick Release group again
23, compel to be butted on the riser part 12 using the lower stopper portion 231, the sleeve part 21 can be made to be produced relative to the riser part 12 again solid
It is fixed.
When operator again will downgrade the height of chair cushion 22, the lower Quick Release group 23 need only be also pulled again, and make the sleeve pipe
Part 21 slides relative to the riser part 12, and is gripped on the handle 24 using hand, and exert a force by the chair cushion unit 20 it is overall to
Lower compacting, the sleeve part 21 is again relative to the slide downward of riser part 12, and when adjusting to required height, operator pulls again
The lower Quick Release group 23, compel to be butted on the riser part 12 using the lower stopper portion 231, and can makes the sleeve part 21 relative to the riser part
12 produce fixation.
And when operator operates Quick Release group 32 on this, the beam ring part 31 can be made to be produced along the sleeve part 21 and moved up and down,
And the relative position of the back cushion 33 and the chair cushion 22 can be adjusted, the user of different types is also can be suitably used for, adjustment is also quite held
Easily.
Therefore, adjustment operation of the present utility model is quite quick, simple, only needs an operator just can easy operation.
In summary, the height adjustable seat unit of the utility model, overall structure is simple, operation is easy, really can
