As Figure 1 and Figure 4, the oxter lifting frame 300 includes foam-rubber cushion 310；The foam-rubber cushion 310 is fixed on oxter
The upper end of lifting frame 300, the lower end of the oxter lifting frame 300 have first crossbeam 320, the front end of the first crossbeam 320
First connecting rod 330 is hinged with, the first connecting rod 330 is connected with the 3rd connecting shaft 130, after the first crossbeam 320
End is hinged with second connecting rod 340, and the second connecting rod 340 is connected with the 4th connecting shaft 140；3rd bearing seat 350a, institute
State and be cased with the 3rd connecting shaft 130 on 3rd bearing seat 350a；It is cased with fourth bearing seat 350b, the fourth bearing seat 350b
4th connecting shaft 140；Fixed block 360,3rd bearing seat 350a and fourth bearing the seat 350b are fixed on the fixed block
On 360.
The oxter lifting frame 300 also includes first support bar 370a, second support bar 370b, connection first and second
Support bar 370b lap bars 370c and two fixed cylinders 380, two fixed cylinders 380 are fixed on the side of the first crossbeam 320
With, the lower end of the first support bar 370a and second support bar 370b are respectively protruding into corresponding fixed cylinder 380, institute
The top that lap bars 370c is located at the fixed cylinder 380 is stated, the fixed cylinder 380 has multiple spacing holes 381, the multiple
Spacing hole is arranged in a row about 381.
Oxter lifting adjuster 390, the oxter lifting adjuster 390 have regulation button 391, iron wire 392, return
Spring 393, bayonet lock spring 394, anti-turn round cover 395 and bayonet lock 396；The iron wire 392 stretches into from first support bar 370a, passes through
Lap bars 370c, passed from second support bar 370b, the both ends of the iron wire 392 are fixedly connected with the card 396, the card
Pin 396 passes through spacing hole 381；There is the regulation button 391 push rod 391a, the push rod 391a to be fixed on the iron wire 392
On；The return spring 393 is located at the upper end of regulation button 391；The bayonet lock spring 394 is used to press the bayonet lock 396
To side；The anti-set 395 of turning round is connected with first support bar 370a and second support bar 370b respectively, and the anti-set 395 of turning round is used
Deformed in preventing the bayonet lock spring 394.
The oxter lifting frame 300 can adjust height by oxter lifting adjuster 390, press regulation button 391,
Push rod 391a is moved up by return spring 393, the push rod 391a moved up withstands iron wire 392, makes iron wire 392 in
Between shrink, because iron wire 392 and bayonet lock 396 are connected so that bayonet lock 396 is pressed from the pinch in of spacing hole 381, bayonet lock spring 394
Contracting, then the height of first support bar 370a and second support bar 370b relative to fixed cylinder 380 is adjusted, regulation to suitable height
When spending, regulation button 391 is unclamped, the bayonet lock spring 394 compressed extends naturally, and bayonet lock 396 is from the limit in fixed cylinder 380
Position hole 381 extends, so that first support bar 370a and second support bar 370b are fixed in fixed cylinder 380；Pass through regulation
The height of oxter lifting frame 300, to match the height of different people.
As shown in Figure 5, Figure 6, the oxter lifting frame 300 includes controllable gas spring 400, and the controllable gas spring 400 wraps
Include：Control button 410, the first floating block 415, drag-line 420, straight pin 440, the second floating block 450, thimble 460 and gas spring
430；The control button 410 is be hinged with first floating block 415, and described one end of drag-line 420 is connected with the first floating block 415, separately
One end penetrates the second floating block 450 and is connected with the straight pin 440；The control button 410 is fixed on the hand lever 210
Topmost, person's manipulation easy to operation.The thimble 460 is located at the upper end of gas spring 430；The controllable gas spring 400 and second connects
Bar 340 is be hinged to be realized the intermittent uplifts of oxter lifting frame 300 and slowly falls.
The control button 410 includes：Button 411, little spring 412, fore-set 413, determine key 414；The button 411 and top
Post 413 is connected, and is set in one end of little spring 412 on the fore-set 413 and is connected with the button 411, the other end with it is described fixed
Key 414 is connected.
When pushing button 411, the fore-set 413 promotes one end of the first floating block 415 to decline, first floating block 415
The other end pull drag-line 420, the drag-line 420 left behind the second floating block 450 by straight pin 440 so that under thimble 460
Drop, so as to which gas spring 430 be unlocked；When decontroling button 411, little spring 412 promotes the return of button 411, now drag-line
420 is locking, and the return of thimble 460, gas spring 430 is in self-locking state.
When rotating clockwise hand lever 210, while pressing control button 410 enables gas spring 430 freely to stretch, and
Rising to oxter lifting frame 300 has certain power-assisted effect.When rotating counterclockwise hand lever 210, unclamp control button makes
Gas spring 430 can not freely stretch, because gas spring 430 and second connecting rod 340 are connected, so oxter lifting frame 300 will not be to
Lower turn.
The lifting process of the oxter lifting frame 300 is：It is reciprocal to pull hand lever 210, and controllable gas spring is pressed repeatedly
400 control button 410, realize the intermittent uplifts of oxter lifting frame 300.Hand lever 210 is being pulled clockwise and is being pressed ＆ hold
When 411, band moving sleeve 220 rotates clockwise, and the flank of tooth 221 of the inner ring of sleeve 220 rotates clockwise band pawl 230 and rotated, and turns
The dynamic one side of ratchet 230 contacts with rotating cylinder 240, drives and rotates cylinder 240 and rotate clockwise, because rotating cylinder 240 and the
One connecting shaft 110 is connected, therefore the first connecting shaft 110 rotates clockwise, the first gear 160a being connected with the first connecting shaft 110
Rotate clockwise, the second gear 160b engaged with first gear 160a is rotated counterclockwise, so as to drive the second connecting shaft 120 inverse
Hour hands rotate, and rotate counterclockwise the first synchronizing wheel 170a being connected in the second connecting shaft 120, the first synchronizing wheel 170a passes through
Timing belt 150 drives the second synchronizing wheel 170b to rotate counterclockwise, and the 3rd connecting shaft 130 rotates counterclockwise, therefore is connected in the 3rd
Second connecting rod 340 in connecting shaft 130 rotates counterclockwise, and drives first connecting rod 330 to rotate counterclockwise, makes oxter lifting frame 300
Rise；
When hand lever 210 rotates counterclockwise and decontrols button 411, the flank of tooth 221 does not engage with ratchet 230, can not drive
Ratchet 230 rotates, thus oxter lifting frame 300 can not upward lifting, but because controllable gas spring 400 is in lockup state, make
Oxter lifting frame 300 will not decline.
The oxter lifting frame 300 is in the process of decline：Armpit is positioned over the foam-rubber cushion of oxter lifting frame 300 by user
On 310, the button 411 of controllable gas spring 400, and pull handle 271 simultaneously are pinned, oxter lifting frame 300 is under gravity
Slowly decline with controllable gas spring 400.Because pulling the handle 271 in the separation assembly 270, connecting pin 273 is driven to be oriented to
Slided in groove 250, connecting pin 273 pulls connecting rod 272, and connecting rod 272 pulls ratchet 230, makes the ratchet 230 and the tooth
Face 221 separates, therefore when oxter lifting frame 300 declines, hand lever 210 remains stationary as.When second connecting rod 340 is horizontal
When, controllable gas spring 400 is in compression most short status.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
