Five, the specific embodiment

Below in conjunction with drawings and Examples structural principle of the present utility model and operation principle are described in further detail.

Embodiment 1, referring to Fig. 1,2, this utility model comprises aF type base 4, dispose the elasticityuniversal wheel 9 of a pair of band slipmat at the lower front end ofbase 4, the infra rear end is provided with a pair of common universal wheel 10, be equipped with in the preceding inboard ofbase 4 andpull handle 26, it is in order to guarantee the stability of chair thatbase 4 is designed to F shape, after old man or people with disability were sitting on the chair, it is anti-skidding that the slipmat on a pair of antiskid elasticuniversal wheel 9 is depressed kiss the earth, behind old man or people with disability's egress of chair, slipmat is upspring, and can walk indoor the promotion voluntarily.When the nursing staff will promote old man or people with disability when walking, when pullinghandle 26, the interlock lever inbase 4 withstands the elasticityuniversal wheel 9 of band slipmat, makes it become the rigidity universal wheel, at this moment just has four universal wheels to support, and can carry out freely.The both sides ofbase 4 are connected with twoRetractive legs 6, be fixed withframe 3 on twoRetractive legs 6, side inframe 3 is connected with gear-box 2 andmotor 1, opposite side inframe 3 is connected withhand crank 5, onframe 3, connecting collapsible andspacing handrail backrest 8,u type seat 7 is being housed inframe 3 andhandrail backrest 8, using for elderly and the disabled's defecation with hinge, at ordinary times, also be provided with an active two-sidedseat 25 onseat 7 plates.

Referring to Fig. 2, what the machine driving of first embodiment of the present utility model adopted is manually with electronic in conjunction with lever hinge structure;Frame 3 is by a horizontal transverse tube, the parallel longitudinal tubule (L tubule) of two levels is welded with two vertical parallel vertical tubes, the electric transmissio mechanism that manually reaches of the present utility model is:hand crank 5 links with an end ofpower transmission shaft 15,power transmission shaft 15 passes from the transverse tube offrame 3, onpower transmission shaft 15, be fixed with twohelical gears 18, the other end atpower transmission shaft 15 is connected with manually-operatedclutch 13, twohelical gears 17 are fixedly connected with two leadingscrews 16 respectively, and with other two helical gears, 18 engagements, two leadingscrews 16 pass from the vertical tube offrame 3 respectively, manually-operatedclutch 13 connects withpower transmission shaft 15 lead keys,bevel gear wheel 12 kinks are onpower transmission shaft 15,bevel gear wheel 12 and bevel pinion 11 engagements, bevel pinion 11 links by reducinggear output shaft 24 and reducinggear 23, andmotor 1 links bymotor shaft 22 and reducinggear 23;

Retractive leg 6 is the parallelogrames that formed by lever hinge, and a hinge point of its lower end is connected withfixing point 21 hinges ofbase 4, and another hinge point is connected with movingfulcrum slide block 20 hinges, and can clocklike slide in the T shape slideway on thebase 4; A hinge point ofRetractive leg 6 upper ends is connected withfixed pivot 14 hinges offrame 3, and another hinge point also is connected with movingfulcrum slide block 20 hinges, and can clocklike slide in the T offrame 3 shape slideway.OnRetractive leg 6, also be provided with thepin nut 19 that matches withscrew mandrel 16, the positive and negativedrive pin nut 19 that rotatablely moves by leadingscrew 16 is done straight reciprocating motion, thereby driveRetractive leg 6 and do stretching motion, also just realized the lifting action of this chair with some groups of hinge parallelogrames.The feed screw nut range of movement is only controlled one group of hinge parallelogram, and the range of movement of some groups of hinge parallelogrames is exactly the several times of the range of movement of feed screw nut, drives parallelogram hinge set multiplication mechanism so thisRetractive leg 6 is a kind of feed screw nuts.

Operation principle of the present utility model is as follows: 1, electronic mode: engage manually-operatedclutch 13,motor 1drives reducing gear 23, reaches the lifting ofRetractive leg 6 by reducinggear output shaft 24, bevel pinion 11,bevel gear wheel 12,power transmission shaft 15 drivehelical gears 18,helical gear 17, leadingscrew 16,pin nut 19; Manual mode: separate manually-operatedclutch 13, drivepower transmission shaft 15 byhand crank 5,helical gear 18,helical gear 17, leadingscrew 16,pin nut 19 reach the lifting ofRetractive leg 6.

Embodiment 2, referring to Fig. 1, and 3,4, the machine driving of second embodiment of this utility model is to adopt hydraulicefficiency elevation structure to realize; Hydraulicefficiency elevation structure compriseshydraulic lifting assembly 27 andcrossbeam 40, be provided with in thehydraulic lifting assembly 27 andhydraulic handle 28 joining valve pistons 29,hydraulic handle 28 links with handle fairlead 42, valve piston 29 is assemblied in thesmall oil tank 30, the lower end ofsmall oil tank 30 respectively bypipeline 31 and 33 andcheck valve 32 andcheck valve 34 link,check valve 34 links withlarge tank 38 again, the lower end oflarge tank 38 is provided withfuel outlet valve 37,crossbeam 40 is connected withRetractive leg 6 byhinge 39,large tank 38 is installed in below thecrossbeam 40, Radix Angelicae Dahuricae (Radix Heraclei Scabridi)stopper rod 41 passes fromcrossbeam 40 centre bores, be fixed onframe 3 centers below, the straight reciprocating motion that Radix Angelicae Dahuricae (Radix Heraclei Scabridi)stopper rod 41 produces drives twoRetractive legs 6 and makes stretching motion, has also just realized the lifting action of this chair.The connecting relation of other parts is withembodiment 1,big piston 41 bar range of movement are only controlled one group of hinge parallelogram, and the range of movement of some groups of hinge parallelogrames is exactly the several times of big piston range of movement, so thisRetractive leg 6 is again a kind of hydraulically powered parallelogram hinge group multiplication mechanism.In the time will rising, upwards pullhydraulic handle 28 with hands, the valve piston 29 that cooperates withsmall oil tank 30 just moves up, produce swabbing action, oil just enterssmall oil tank 30 cavity of resorptions fromfuel tank 35 throughcheck valve 32,pipeline 31, when pressinghydraulic handle 28 effectively downwards, when valve piston 29 moved down, the oil that just will sucksmall oil tank 30 cavity of resorptions was pressed intolarge tank 38 cavity of resorptions throughpipeline 33, check valve 34.This moment,check valve 32 was obstructed, just forced big piston to move up, jack-upframe 3, so constantly pullhydraulic handle 28 up and down, just oil can be pressed into off and onlarge tank 38 cavity of resorptions,frame 3 is risen, because the existence ofcheck valve 34 makes the oil that enterslarge tank 38 not flow backwards.In the time will descending, then can turnopen valve 37, the oil oflarge tank 38 just can be gone intofuel tank 35 36 times through piping, Radix Angelicae Dahuricae (Radix Heraclei Scabridi)stopper rod 41 just moves downward,frame 3 under action of gravity also along with downward landing.

The utlity model has advantages such as simple in structure, practical reliable, according to principle of the present utility model, also can produce other series of products according to user's needs, as: just help upright stool, chair lift, lifting sofa and lifting wheelchair etc. were of great benefit to the quality of life of improving the elderly and the disabled, can be widely used in sanatorium, senior citizens' care centre, high-grade ward, retired old man family and individual.
