It is equipped with for being moved forward leg support is acted the support slipper turned over, driving rack is driven phase by connecting rod and support slipper
Even, front end and the support slipper of connecting rod are hinged and connected, and rear end and the driving rack of connecting rod are hinged and connected, and backrest has to incline with seat board
The backrest tiltedly arranged lies down position by position and downwardly turning over to the backrest for being supported in horizontal attitude by the backrest support rods on bedstead,
Leg support there is the leg being in tilted layout with seat board to support support level and be supported sliding block and jack up and be supported sliding block be supported in horizontal attitude
Leg support lie down position.
It is provided with gear pin shaft hole on the transmission gear, seat board pin corresponding with gear pin shaft hole is provided on seat board
Axis hole, nursing wheelchair further include for being plugged in gear pin shaft hole and seat board pin shaft hole so that backrest is positioned at backrest by position
Backrest shop bolt.
Be provided on the seat board at least two along the longitudinal direction it is spaced apart be used for and the seat board support rod on bedstead
The seat board location hole of adaptation positioning and plug-in mounting cooperation in left-right direction.
The left side of seat board location hole is the import of seat board support rod, and seat board pin shaft hole is located at the right side of seat board, and nursing wheelchair is also
Including being located at the unlock connecting plate on the right side of seat board, backrest shop bolt is fixed on the unlock connecting plate, is unlocked and is also set up on connecting plate
Have and is used for the spaced apart guide pin of backrest shop bolt and in corresponding seat board location hole by seat board support rod top
The unlock pin pushed away, guiding movement is assemblied on seat board guide pin in left-right direction, is provided between guide pin and seat board
Apply the backrest retaining spring towards left direction active force to seat board.
The invention has the benefit that there are two types of postures for the nursing wheelchair in the present invention, one is what is used as wheelchair
Wheelchair posture, another is the bed body posture as bed body a part, as wheelchair in use, backrest be in backrest rely on
Position, leg support support support level in leg, and patient can be sitting on wheelchair, and nursing staff can push patient and move around, and work as patient
When needing rest, it is not required to mobile patient, backrest is downwardly turned over to backrest and is lain down position, the downside of backrest is by the backrest branch on bedstead
Strut supports and is positioned at backrest and lies down position, and during backrest downwardly turns over, transmission gear moves forward with driving rack,
Driving rack is moved by connecting rod with support slipper forward during moving forward, during support slipper moves forward
Leg support is risen, and supporting leg supports the position so that leg support of the leg support in horizontal attitude lies down, at this time since backrest is by bedstead
Backrest support rods support and cannot continue to downwardly turn over, therefore the position of support slipper is also reliable, it is ensured that support to leg
Firm support, such backrest, seat board and leg support be all just horizontal attitude, can be together with another block bed board on bedstead
Bed is formed, patient has arrived on bed without mobile, very time saving and energy saving.
