Top, at this time entire mechanism can be locked；In the lock sheet 10 forward horizontal elongated slot of retraction, entire mechanism is then at release at this time
In unlocked state；
For 1 front end two side of support base to being provided with coaxial a pair of of circular hole, which is installed with lifting handle 8
Cylindrical-shaped main body, lifting handle 8 be located at the termination point casing in 1 inner cavity of support base equipped with lifting pressing plate 6 and lifting torsional spring 7, rise
Decompression board 6 is contacted with the front end curved boom of lifting regulating rod 4, and lifting torsional spring 7 is used to provide back stretch to lifting pressing plate 6；
Lifting handle 8 is located at the end outside support base 1 and is fixedly installed hand pressure board, realizes that effortless rotated with hand of user lifts
Handle 8；
Locking adjusting rod 12, the end that 12 outside of locking adjusting rod is exposed are installed in the cylindrical-shaped main body of lifting handle 8
It is fixed with set lever 17, one end that locking adjusting rod 12 is located in 1 inner cavity of support base is supported in side wall circular hole, and inner end
Locking torsional spring 15 and locking regulating part 13 are set on the body of rod of exposing；Locking regulating part 13 includes the galianconism and length of integrally connected
Arm, long-armed outer diameter end setting there are two half 8-shaped groove of band elasticity, the two and half 8-shaped groove only there are one with limit
(a corresponding locking state, another corresponds to unlocked state for position 11 screens of nail contact；One is to unclamp position in other words, another
It is locking position), locking regulating part 13 is fixed on by fixing screws 14 on locking adjusting rod 12；Lock one end spring of torsional spring 15
Bar is inserted into the stria hole of 10 front of lock sheet, and the galianconism of the spring lever insertion locking regulating part 13 of locking 15 other end of torsional spring is inserted
In slot so that locking regulating part 13 and locking 12 unitary rotation of adjusting rod, while locking regulating part 13 and locking torsional spring 15 is driven to drive
Dynamic lock sheet 10 is moved forward and backward；
It is radially fixed on locking adjusting rod 12 to there is pin 16, pin 16 to be located between lifting pressing plate 6 and locking torsional spring 15,
Pin 16 is for preventing locking adjusting rod 12 from deviating from from the cylindrical-shaped main body of lifting handle 8；
With reference to Fig. 3,1 rear end two side walls of support base are provided with a pair of of through-hole, this cuts with scissors through-hole by shaft and connecting plate 18
It connects, connecting plate 18 is connect with swivel chair bottom fixed board again.
The operation principle of the utility model is,
1) elevating function
The head of lifting handle 8 is penetrated from the side wall of the side of support base 1, and buckle structure and lifting pressing plate 6 are set up in head
Inner wall block to form an entirety, enable lifting handle 8 outside rotate when drive lifting pressing plate 6 rotate, lifting
The long radial protrusive board of pressing plate 6 is used to contradict the front end curved boom of lifting regulating rod 4, makes lifting pressing plate 6 when around axis rotates
Time can subdue lifting regulating rod 4, so that lifting regulating rod 4 is rotated along intermediate straight-bar axis, the rear end of lifting regulating rod 4
Direction switch is opened on the head of curved boom upsetting homalocephalus portion just compressed gas pressure bar.
Illustrating, 1) lifting pressing plate 6 other side is minor axis to protrusive board, effect is anti-in back-pressure lifting regulating rod 4
To when rotation, 1 bottom internal of support base can be contradicted, limitation lifts the slewing area of pressing plate 6；2) torsion of torsional spring 7 is lifted
Spring force is consistent with the desired operation direction of opening function of user, and auxiliary pushes lifting pressing plate 6, plays labor-saving effect；Meanwhile it preventing
When not having external force, lifting pressing plate 6, which is presented, to be loosened, and the case where shaking of lifting handle 8 occurs so that lifting handle 8 can begin
Lifting regulating rod 4 is kept to contradict the state in air pressure club head eventually.
2) locking function
The outer end of locking adjusting rod 12 is fixedly connected with set lever 17, and locking adjusting rod 12 penetrates lifting handle 8 and lock
The circular hole in tight 13 axle center of regulating part is pierced by from 13 other side of locking regulating part in the circular hole for being supported on side wall.Fixing screws 14 will
Locking regulating part 13 is fixed on locking adjusting rod 12 so that locking regulating part 13 is rotated synchronously with locking adjusting rod 12.
The galianconism slot of locking regulating part 13 is caught in one end of locking torsional spring 15, and it is corresponding thin that the other end is inserted into lock sheet 10
In slot；
The long-armed spring groove for being provided with half 8-shaped for locking regulating part 13 makes the groove of half 8-shaped contradict banking pin
11 outer surface limits the unintentional rotation for locking regulating part 13 under external force；
Set lever 17 is rotated clockwise, one and half 8 word grooves gram of locking regulating part 13 can be made under external force
The limitation for taking banking pin 11, into the groove of another half 8 word, locking adjusting rod 12 is connected to an arm of locking torsional spring 15, lock
Tight torsional spring 15 drives 10 retraction of lock sheet locking in the horizontal elongated slot of fixed board 2 and locking bed 9, and mechanism unlocks.
3) protective function of trying hard to keep is returned
If lock sheet 10 stretches out the part for the plate 2 that is locked by external force, lock sheet 10 will not move, and lock torsional spring 15
In stored energy state, after waiting 10 external force of lock sheets to disappear, under the action of locking 15 elastic force of torsional spring, lock sheet 10 can just unclamp, this
The phenomenon that a storage power is unclamped, can effectively prevent entire mechanism from switching to releasing orientation by locking state suddenly and causing to human body
Unexpected injury, referred to as return protective function of trying hard to keep.
