The center jointed shaft 7 of described crane 4 is provided with the push-pull bar 8 of level to the middle part of the frame body between the preceding bottom, the shaft middle part of push-pull bar 8 is hinged with the termination of hydraulic cylinder 5 top telescopic shafts 9, promptly be convenient to when hydraulic cylinder 5 action to promote crane 4 stably and change the intersecting angle of crane 4, thereby reach the purpose of lifting seat 2 by push-pull bar 8; For the telescopic shaft 9 that makes hydraulic cylinder 5 can not hinder the action of crane 4 when the action, hydraulic cylinder 5 integral inclinations and the middle part of its bottom and framework 1 rear end is hinged; Operate the seat lifting of wheelchair voluntarily for ease of the end user, hydraulic cylinder 5 is made as the electric hydaulic cylinder, its hydraulic operation switch is arranged on the described wheelchair and is positioned at the position that the wheelchair end user can conveniently touch;
In addition, hydraulic cylinder 5 can also be made as the hand-hydraulic cylinder, its pressing mechanism comprises foot-driven lever 10, depression bar 11 and connecting rod 12; Described foot-driven lever 10 is parallel with the edge of framework 1 rear end and be provided with bending on shaft, the bending part of foot-driven lever 10 is hinged with the fulcrum block 13 that is located at bottom surface, framework 1 rear end, the bar head process of foot-driven lever 10 long bending edges one ends goes out rear end one side of framework 1 and is provided with the face of trampling 14, and the bar head of foot-driven lever 10 short bending edges one ends is fixedly connected with steel wire rope 15; The roller 16 that described steel wire rope 15 twined on framework 1 bottom surface that is located between framework 1 rear end middle part and the fulcrum block 13 then is connected with an end of depression bar 11, the corresponding decussation that is of direction that rotates when the rotation direction of roller 16 moves ahead with framework 1 bottom chair wheel 17 is made action thereby be convenient to drive depression bar 11 by foot-driven lever 10; Described depression bar 11 is the arcuate structure of inner arc towards wheelchair the place ahead, the middle part of depression bar 11 is hinged on middle part, framework 1 rear end, the other end of depression bar 11 is positioned at framework 1 top and hinged with an end of connecting rod 12, the pressuring shaft 18 of the other end of connecting rod 12 and hydraulic cylinder 5 is hinged, thereby being convenient to manpower comes hydraulic cylinder 5 pressurizations by the face of trampling on the foot-driven lever 10 of trampling 14, to be foot-driven lever 10 drive depression bars 11 by steel wire rope 15 does vertically action, and then, make hydraulic cylinder 5 actions by connecting rod 12 drive pressuring shaft 18.
In conjunction with the accompanying drawings 3～4, for making the liftable wheelchair of described seat provide more comfortable facility, can on described wheelchair, add to be provided with the upper side of calf plate 19 in the seat 2 and pedal 20 to be risen holder extremely keeps level with seat board 3 upper side horizontal tray for the end user; When adding horizontal tray, be preferably and be articulated and connected, and be fixed with support member 21 to the inclination of the wheelchair back lower place in the bottom of pedal 20 rear ends with being made as between the calf plate in the seat 2 19 and seat board 3 and the pedal 20; Described support member 21 is hinged with an end of catch bar 22, and the other end branch of catch bar 22 forms two both-end heads that are parallel to each other, and the lower hinge of this termination and seat board 3 front ends; Described seat board 3 front bottom end are hinged with hook 23; Be preferably in the hinged junction of described hook 23 and seat board 3 and be provided with the torsion spring 32 that is used to limit hook 23 swing position; Be provided with the fixed axis 24 of corresponding hook 23 between two terminations of described catch bar 22 both-end heads, and a head bottom part in the both-end head is provided with arcuation projection 25, and another termination is provided with semicircular projections 26 near catch bar 22 with the bottom of seat board 3 hinged places and the position of corresponding arcuation projection 25 rear ends;
The center jointed shaft 7 of described crane 4 to the frame body between its preceding paragraph end middle part is provided with the support bar 27 of level, and the shaft middle part of support bar 27 is fixed with and the push rod 29 1 ends part 28 that is articulated and connected; Described push rod 29 shafts are provided with the bending of inner arc towards the below, and the bending of push rod 29 is hinged on the bottom of seat board 3 front ends; The other end of push rod 29 is hinged with the support roller 30 of corresponding arcuation projection 25 bottoms, is hinged with the support wheel 31 of corresponding semicircular projections 26 bottoms on push rod 29 shafts between support roller 30 and push rod 29 bendings; When crane 4 rises, support bar 27 promotes push rod 29, and by support roller 30 on the push rod 29 and support wheel 31 corresponding drive catch bars 22 actions, catch bar 22 and support member 21 hinged ends upwards rise and the upper side of pedal 20 and calf plate 19 are risen to upper side level with seat board 3, at this moment, support wheel 31 is got over to the rear end by the front end of semicircular projections 26, and fixed axis 24 is hung over hook prevent that pedal 20 and calf plate 19 from resetting downwards on 23, even pedal 20, the upper side of calf plate 19 and seat board 3 remains on same level, otherwise and the operation promptly can pedal 20 and calf plate 19 be resetted;
Because support wheel 31 makes the spacing between catch bar 22 and the support wheel 31 that the moment change take place when moving forward and backward in semicircular projections 26 bottoms, also make catch bar 22 that certain angle of inclination has been arranged, and the axle body that drives fixed axis 24 has simultaneously produced certain angle variation, thereby when support wheel 31 is got over to the rear end by the front end of semicircular projections 26 bottoms, fixed axis 24 can be firm hang over the hook 23 on, and when support wheel 31 was got over to front end by the rear end of semicircular projections 26 bottoms, 24 of fixed axis can be by coming off on the hook 23; As required, can between two terminations of catch bar 22 both-end heads, be provided with stage clip 33, one end correspondence of described stage clip 33 is fixed on the below of fixed axis 24, the other end of stage clip 33 contacts with fixed axis 24 axle bodies of the close first side of catch bar 22 both-ends, thereby can increase the dynamics of being affiliated between hook 23 and the fixed axis 24 by the compressing of stage clip 33, guarantee that further hook 23 and fixed axis 24 can delamination not come off; For ease of link up with 23 finish and fixed axis 24 between be affiliated to and come off, the angle that forms between stage clip 33 and fixed axis 24 axle bodies is corresponding with the lowermost end of linking up with 23.
Implement the liftable wheelchair of seat of the present invention, when adopting the electric hydaulic cylinder, only the seat lifting that needs the end user to control wheelchair by the hydraulic operation switch gets final product, and when adopting the hand-hydraulic cylinder, needs other staff to help finish the lifting of seat by the operation pressing mechanism.
Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
