Described scalable shelf organization establishes of taking down the exhibits moves back and forth the below of handrail 1 in wheelchair both sides, comprise shelf 47, articulated linkage 48, shelf 47 and articulated linkage 48 use rotatable snap close to be connected, after shelf 47 launches, rotate the knob 49 on shelf 47, the shelf 47 of both sides is connected as one.
Be oval hole in the middle part of described seat plate 37, seat plate 37 is also provided with two pieces of soft medicated cushions 41 of rectangle, the oval hole location of seat plate 37 is provided with to coincide with ellipse and to be divided into the seating pad 42 of two pieces, left and right, and the quality of described seating pad 42 is identical with seat plate 37; Seat plate is also provided with for 37 times and the base plate 43 of seat plate with elliptical shape, and seat plate 37 times sides are provided with hinge 44, and hinge 44 is by hinge buckle connecting bottom board 43, and the opposite side of base plate 43 is connected to seat plate 37 times by snap close 46.Two pieces, left and right described in the present embodiment seating pad 42 and the soft medicated cushion 41 in upper strata can connect as one, and also can independently use.
Operation principle of the present utility model is as follows:
Reciprocation conversion mechanism, changeable overrunning clutch mechanism and hand-operated breaking mechanism have combined and have converted the straight reciprocating motion of handrail to circumference reciprocating motion, and then be converted into the circular motion of Timing Belt driving wheel, and then the drivewheel of wheelchair is driven to move forward or backwards and brake.Under the synergism of each connecting rod, rotating shaft, lock dog, slide block, chute and air pressure rod, five seat cushion linkage mechanisms complete five aspects such as headrest, folding back, backrest, seat plate and pedal and link simultaneously and adjust sitting posture.
When user goes to toilet, the cushion of left and right and seating pad do not take off by left and right sides status, after going to toilet, can also open base plate snap close 46 voluntarily, so base plate 43 is flapped toward, and then takes off base plate voluntarily and carry out cleaning and installing.
When backrest 26 hypsokinesis certain angle, push rod slide block 29 skids off in fixing chute 45, enter lock dog 30 inner simultaneously, and drive lock dog 30 to rotate along axle center 57, when after lock dog 30 half-twist, shift fork 54 ejects, and stops lock dog 30 to reset, it is inner that namely push rod slide block 29 is locked in lock dog 30, no longer has relative motion with backrest;
When backrest 26 resets, push rod slide block 29 enters in chute, secondary shifting block 55 touches block 56 tailing edge axle center 58 and rotates, shift fork 54 is driven to rotate along axle center 59, the locking of shift fork 54 pairs of lock dogs 30 is removed, lock dog 30 resets under spring force, removes the locking effect to push rod slide block 29, and push rod slide block 29 recovers the relative motion trend with backrest 26;
When push rod 60 is under chute effect, when sliding along chute 61, secondary push rod 62 slides along chute 63, drives the upper end of lumbar support 64 to slide simultaneously, the height of projection of lumbar support 64 is declined;
When push rod 60 moves upward along chute 61, push rod 65 is pushed and moves upward, rotates along pin joint 66 simultaneously; Push rod 65 promotes push rod 68 by pin joint 67 and slides along chute 69; Push rod 68 promotes folding back 25 by pin joint 70 and rotates along axle center 71;
When folding back 25 rotates along axle center 71, rocking bar 501 rotates along axle center 72, and by pin joint 73, pulls rocking bar 502 to rotate along pin joint 74, and headrest 24 opens thereupon.
Scalable shelf 47 of taking down the exhibits carries out flexible taking down the exhibits by articulated linkage 48, when using shelf 47, both sides shelf 47 is boosted, rotation is set level, after shelf 47 launches, rotate the knob 49 on shelf 47, namely the shelf 47 of both sides connects as one, and left and right sides shelf 47 also can individually use.
The above is only preferred implementation of the present utility model; be not limited to this utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
