Specific embodiment
1-6 and embodiment with reference to the accompanying drawing, are described in further detail specific embodiment of the present utility model.With
Lower embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of medical treatment wheelchair pedal turnover mechanism, including foot pedal 1, foot pedal 1 include the pedal body 11 for leg rest
With the axle sleeve 12 for connecting a rotary shaft 2, the axial one of side of axle sleeve 12 is connected with 11 side of pedal body, and with
Pedal 1 is integrated formed structure, and axle sleeve 12 can be cylindrical body, is also possible to can be cube, axle sleeve 12 is set in rotation
The middle part of axis 2, and being rotated around rotary shaft 2, enable pedal body 11 according to patient be sitting posture or lying posture and backward
Overturning is overturn forward.
2 one end of rotary shaft is connected with a connecting rod 3 for being connected to wheelchair pedal assembly on wheelchair, specifically, even
Extension bar 3 is connected on the leg support 13 of wheelchair, and leg support 13 is hinged on wheelchair seat plate 10, is able to achieve and is spun upside down.Work as patient
When needing to lie low, leg support 13 have to it is parallel with seat plate 10,1 extending direction of foot pedal with ground be it is vertical, can not just put
Foot, usage experience is very bad, so it is required that foot pedal 1 also being capable of front and back overturning.
There is a square 21 in one end that rotary shaft 2 is connect with connecting rod 3, and 2 other end of rotary shaft, which is cased with one, prevents axle sleeve 12
The sleeve 9 to fall off from rotary shaft 2, so that axle sleeve 12 is folded between sleeve 9 and connection 3.
Specifically, sleeve 9 and rotary shaft 2 are interference connection or sleeve 9 and rotary shaft 2 is threaded connection, it is threadedly coupled
Specific implementation be that internal screw thread is equipped with inside sleeve 9, one end that rotary shaft 2 connect with sleeve 9 is rotated equipped with external screw thread
Axis 2 screws in inside sleeve 9 with externally threaded one end.
Connecting rod 3 includes two L shape connectors 32 disposed in parallel, and there are accommodating squares between two L shape connectors 32
21 spacing, L shape connector 32 include the first flanging 321 for connecting wheelchair and the second flanging for connecting rotary shaft 2
322, square 21 is folded in centre, the axial direction of two the second flangings 322 by the second flanging 322 of two L shape connectors 32
Consistent with the length direction of square 21, two the first flangings 321 and square 21 are at least connected with a fastener 4.
Because there is spacing between two L shape connectors 32, at least one pin 5 of two the first flangings 321
It links together, the outside of the first flanging 321 far from foot pedal ontology 11 is stretched out in 5 one end of pin, and pin 5 stretches out the first flanging
The one end in 321 outsides is connect with leg support 13.
The lateral surface of second flanging 322 of adjacent L shape connector 32, which is equipped with, with pedal body 11 prevents pedal body 11
The limit inferior limited block 6 moved downward, lower position and close axle sleeve 12 of the limit inferior limited block 6 in foot pedal ontology 11, when
When foot pedal ontology 11 downwardly turns over parallel with seat plate 10 in other words to ground, limit inferior limited block 6 can withstand foot pedal
Ontology 11 prevents foot pedal ontology 11 from continuing to downwardly turn over.
Extending direction and the axial consistent and adjacent inside sidewalls of rotary shaft 2 are equipped with a upper limit limited block 7, axis on axle sleeve 12
Cover the diameter length that 12 bottoms exceed rotary shaft 2, the extending direction of limit spacing block 7 and axial consistent, the upper limit limit of rotary shaft 2
Be equipped with spacing between the position top of block 7 and rotary shaft 2, the setting of spacing be in order to prevent 7 top and rotary shaft 2 of upper limit limited block it
Between contact, and can not rotary sleeve 12, so that the front and rear angles of foot pedal 1 can not be adjusted.
Top in rotary shaft 2 positioned at 7 top surface of limes superiors limited block is equipped with the cylindrical type for withstanding limes superiors limited block 7
Boss 8, when foot pedal ontology 11 is flipped up it is parallel with seat plate 10 in other words to ground when, cylindrical type boss 8 can be withstood
Limes superiors limited block 7 prevents foot pedal ontology 11 from continuing up overturning.
Working principle of the utility model is: when patient needs to lie down, so that leg support 13 is parallel with wheelchair seat plate 10, but
That foot pedal 1 is also perpendicular to wheelchair seat plate 10, can not leg rest, need to downwardly turn over foot pedal 1；When patient needs to sit up
When so that leg support 13 is vertical with wheelchair seat plate 10, but foot pedal 1 is also perpendicular to wheelchair seat plate 10, can not leg rest, need
It is flipped up foot pedal 1.
In conclusion above embodiment is not the restricted embodiment for being the utility model, the technology of all this fields
The modification or equivalent deformation that personnel are carried out on the basis of the substantive content of the utility model, in the utility model
Technology scope.
