The right end of ontology 2-1;
It can be manually rotated manual bull stick 1-4, engaged from mantle tooth 1-3 with active conical tooth 1-6 by rear stroke of frame, drive fixed connect
It connects in rear stroke of frame from the rear stroke of frame bull stick 1-2 rotation on mantle tooth 1-3, by the effect of rear stroke of frame bull stick boss, so that rear draw
Frame bull stick boss slides in sliding slot 2-3-1, drives rotation screw rod 2-3 to rotate by sliding slot 2-3-1, because rotating screw rod 2-
Frame ontology 2-1 is drawn before being both connected in 3 both ends so that preceding stroke of frame ontology 2-1 reverse slide so that preceding stroke of frame 2 and draw afterwards frame 1 it
Between spacing change so that the length of device changes;Manual toggle slide bar 5, so that slide bar 5 is in inner sleeve slide bar notch
Transverse shifting in 3-4-1, and adjusted between front stretching frame 3-1 and bottom plate 3-2 along notch 3-1-1 vertical shift simultaneously
Spacing, then telescopic frame 3-1 stirs left end slide bar 5 forward, so that slide bar 5 slides into card slot 3-1-2, finishing device height
Adjusting and device height locking.
A kind of physical training special medical nursing bed of the invention, its working principle is that:
In use, can be manually rotated manual bull stick 1-4, engaged from mantle tooth 1-3 with active conical tooth 1-6 by rear stroke of frame, band
It is dynamic be fixedly connected on after draw frame from the rear stroke of frame bull stick 1-2 rotation on mantle tooth 1-3, by the effect of rear stroke of frame bull stick boss,
It is slided in sliding slot 2-3-1 so that drawing frame bull stick boss afterwards, drives rotation screw rod 2-3 to rotate by sliding slot 2-3-1, because turning
Frame ontology 2-1 is drawn before being both connected in the both ends of dynamic screw rod 2-3, so that preceding stroke of frame ontology 2-1 reverse slide, so that preceding stroke of 2 He of frame
The spacing drawn between frame 1 afterwards changes, so that the length of device changes;Manual toggle slide bar 5, so that including slide bar 5
Transverse shifting in slide bar notch 3-4-1 is covered, and adjusts front stretching frame 3-1 and bottom plate along notch 3-1-1 vertical shift simultaneously
Spacing between 3-2, then telescopic frame 3-1 stirs left end slide bar 5 forward, so that slide bar 5 slides into card slot 3-1-2, it is complete
At the adjusting of device height and the locking of device height;Need to adjust the wounded lie nest position when, square on the outside of manual-up promotion
Shape frame 6-3-1 passes through transmission gear 6-1-5 and inside rack gear 6-3-7 so that connecting column 6-1-4 is rotated in rotation hole 6-3-3
Engaged transmission pass through so that rectangle frame 6-3-1 is opposite on the outside moves around transmission gear 6-1-5 to upside by L bar 6-3-8
Engaged transmission between rotatable gear 6-3-5 and upside stationary rack plate 6-3-4, so that upside stationary rack plate 6-3-4 is inverse
Hour hands rotation, and by the engaged transmission between rotatable gear 6-3-5 and rack gear connecting rod 6-3-6, so that rack gear connecting rod
6-3-6 is moved along L bar 6-3-8 to upper right side, by being fixedly connected between rack gear connecting rod 6-3-6 and connecting rod 6-2-2,
So that back backup plate ontology 6-2-1 is moved along outside rectangular frame 6-3-1 to upper right side, when connecting column 6-1-4 is in rotation hole 6-
In 3-3 when rotation, clamp boss 6-4-1 is stuck in card slot 6-1-3, is matched by card slot 6-1-3 and the gap of clamp boss 6-4-1
It closes, so that being leaned against when on the backup plate ontology 6-2-1 of back in the wounded, due to the effect of wounded gravity itself, so that clamp boss
The downside of 6-4-1 and the lower end of card slot 6-1-3 inner wall press together, so that clamp boss 6-4-1 is without departing from card slot 6-1-
3;When needing to reduce the use angle of back backup plate ontology 6-2-1, limit casing 6-5 is pulled outward, so that cylindricality slide bar
6-4-2 is moved outward along sliding panel 6-3-2, so that clamp boss 6-4-1 and card slot 6-1-3 is detached from, presses back to downside
Portion backup plate ontology 6-2-1 passes through transmission gear 6-1-5 and inner tines so that connecting column 6-1-4 is rotated in rotation hole 6-3-3
The engaged transmission of 6-3-7, so that rectangle frame 6-3-1 is opposite on the outside transports around transmission gear 6-1-5 to downside by L bar 6-3-8
It is dynamic, by the engaged transmission between rotatable gear 6-3-5 and upside stationary rack plate 6-3-4, so that upside stationary rack plate
6-3-4 is rotated clockwise, and by the engaged transmission between rotatable gear 6-3-5 and rack gear connecting rod 6-3-6, so that rack gear
Connecting rod 6-3-6 is moved along L bar 6-3-8 to lower right side, passes through consolidating between rack gear connecting rod 6-3-6 and connecting rod 6-2-2
Fixed connection, so that back backup plate ontology 6-2-1 is moved along outside rectangular frame 6-3-1 to lower right side, so that low back backup plate sheet
The angle of body 6-2-1 and preceding stroke of frame ontology 2-1 reduces, and unclamps limit casing 6-5, under the action of covering spring 6-4-3 elastic force, again
So that clamp boss 6-4-1 is connected together with card slot 6-1-3, the fixation to the back position backup plate ontology 6-2-1 is completed.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
