Detailed description of the invention
Describe concrete structure of the present utility model in detail according to Fig. 1-6.Above vehicle frame in figure (17), be provided with guide rail (27), guide rail (27) is inlaid with slidably guide rail slide block (24) above, and guide rail slide block (24) upper end is hinged with two chain extension bars (31) and two chaining parts (23) respectively and rotatably { as Figure 1-4 }.The upper end of backrest pole (21) is connected to a fixed with backrest (2) and air-leg chaining part (4) respectively, be hinged with upper handrail (5) and rotatably, middle be hinged with seat support (7) and rotatably, lower end and backrest and pedal trace (18) are hinged and rotatably.The upper end of pedal pole (12) and seat support (7) are hinged and rotatably, middle be hinged with pedal trace (18) and rotatably, lower end and pedal (13) are hinged and rotatably { as shown in Figure 3 }.The upper end of seat support lowering or hoisting gear (9) and linking axes (19) are hinged and rotatably, the lifting transmission case (26) of seat support lowering or hoisting gear (9) lower end is hinged with vehicle frame (17) and rotatably, lifting transmission case (26) is provided with lifting rocking bar (10) and lifting hand cranking handle (11).{ as shown in Fig. 4-5 }
Rocking-turn lifting hand cranking handle (11) clockwise, lifting transmission case (26) can slowly promote seat support lowering or hoisting gear (9) and rise, and it will drive seat support (7) to rise.The seat support (7) rising pulls respectively again the chaining part (23) and the chain extension bar (31) that are hinged mobile, they again sliding guides slide block (24) move backward along guide rail (27), make seat support (7) and backrest (2) synchronously increase, backrest pole (21) will keep the angle of sitting posture constant in rising, and pedal pole (12) finally completes stance state { as shown in Fig. 4-5 } to the back lower place to moving under the pulling of backrest and pedal trace (18).
Rocking-turn lifting hand cranking handle (11) counterclockwise, lifting transmission case (26) can slowly pull seat support lowering or hoisting gear (9) to decline, and it will drive seat support (7) decline { as shown in Fig. 4-5 }.
Lifting friction pulley guide rail (33) is connected to a fixed with vehicle frame (17), and lifting friction pulley slide block (34) is linked { as Figure 4-Figure 6 } with lifting rocking bar (10), lifting friction pulley guide rail (33), lifting friction pulley (32), lifting friction pulley clutch operating lever (35), lifting friction pulley gag lever post (36) respectively.
Move backward lifting friction pulley clutch operating lever (35) and can make lifting friction pulley (32) contact with trailing wheel (15), at this moment promote forward or backward wheel-chair lifting transmission case (26) and can slowly drive seat support lowering or hoisting gear (9) to rise or decline { as Figure 4-Figure 6 }.
Moving forward lifting friction pulley clutch operating lever (35) can make lifting friction pulley (32) separate { as Figure 4-Figure 6 } with trailing wheel (15).
The upper end of air-leg (20) and air-leg chaining part (4) are hinged and rotatably, lower end and linking axes (19) are hinged and rotatably, lower end is provided with the stear drawing line { as shown in Figure 3 } being linked with backrest action bars (22).
Move backrest stick (22) and make the slow sweptback while of backrest (2), backrest pole (21) can drive backrest and pedal trace (18) and pedal pole (12) and pedal (13) to lift to front upper place.When again moving backward backrest stick (22) when reset and simultaneously promoting forward backrest (2) and return to initial sitting posture, unclamping backrest stick (22) can { as shown in Figure 3 }.
Upper handrail (5) can above handrail and backrest pole chain connecting plate (30) turn over for axle center makes handle (3) and upper handrail (5) interlock.Lower handrail (6) rear end is provided with linking axes (29) after lower handrail, front end is provided with lower handrail turnover spring button (8), lower handrail (6) can following handrail after linking axes (29) axle center turn over { as Figure 1-4 }.
1, when sitting posture state need to be transformed into lying posture state: nursing staff can a hands pushes away forward and holds up backrest (2), another hands is moved backward backrest stick (22) and is made the slow sweptback while of backrest (2), and backrest pole (21) can drive backrest and pedal trace (18) and pedal pole (12) and pedal (13) to lift { as shown in Figure 3 } to front upper place.
While recovering sitting posture state, again move backward and when backrest stick (22) promotes forward backrest (2) to initial sitting posture simultaneously, unclamp backrest stick (22) and get final product { as shown in Figure 1-2 }.
2, when sitting posture state need to be transformed into stance state: nursing staff is rocking-turn lifting hand cranking handle (11) clockwise, lifting transmission case (26) can slowly promote seat support lowering or hoisting gear (9) and rise, and it will drive seat support (7) to rise.The seat support (7) rising pulls respectively again the chaining part (23) and the chain extension bar (31) that are hinged mobile, they again sliding guides slide block (24) move backward along guide rail (27), make seat support (7) and backrest (2) synchronously increase, backrest pole (21) will keep the angle of sitting posture constant in rising, and pedal pole (12) finally completes stance state { as shown in Figure 4 } to the back lower place to moving under the pulling of backrest and pedal trace (18).
State { as shown in Figure 1-2 } when counterclockwise rocking-turn lifting hand cranking handle (11) just can return to initial sitting posture by seat support (7) and backrest (2) and pedal trace (18) while recovering sitting posture state.
