It is short, open in small distance, if obese patient, the distance that front plate 6 and rear plate 10 slide in and out simultaneously is elongated, open away from
From becoming greatly, be advantageous to later stage upset and clamp, be adapted to different crowd, it is different according to weight in patients, automatically adjust and suitably open chi
Very little, automatization level is high；
After backing plate 2 is steady, push rod 33 is pulled to travel forward, the front end of push rod 33 is provided with raised tilted block, is advantageous to bullet block 35
Horizontally slip, when push rod 33 departs from square groove, stop drag push rod 33, bullet block 35 can effectively be consolidated under the action of the spring
Determine the position of push rod 33, during push rod 33 is pulled, push rod 33 drives motion bar 34 to travel forward, and motion bar 34 is to stretch
Contracting bar, motion bar 34 can extrude the lower end protruding block of backing plate 2, have the function that fixed backing plate 2, can so ensure backing plate 2
Position will not change；
Then both legs are stretched, pedal 11 is promoted to left movement with pin, pedal 11 drives the 3rd rack 12 to left movement, and first
The rack 7 of rack 3 and second is fixedly connected with the 3rd rack 12, so the first rack 3 and the second rack 7 in the backing plate 2 to
Left slip, the first rack 3 depart from the first partial gear 4, and the second rack 7 departs from the second partial gear 8, the 3rd rack
12 drive connecting rods 30 are moved in sliding groove, and in the presence of connecting rod 30, band movable slider 31 moves right, and then extrudes the
One spring 32, have the function that to compress backing plate 2, after both legs are stretched out, promote push rod 33 to move backward, lock the 3rd rack
12, now backing plate 2 change in location will not occur in the presence of the first spring 32；
During pedal 11 is to left movement, the 3rd rack 12 first slides a segment distance to the left, ensures the first rack 3 and the
One partial gear 4 departs from, and the second rack 7 departs from the second partial gear 8, then the 3rd rack 12 engagement first gear 13
Rotate, first gear 13 is rotatablely connected through bearing and drive shaft 14, is provided with ratchet 15 in first gear 13, ratchet 15 be engaged with and
The rotating disc 16 that drive shaft 14 is slidably connected, drive shaft 14 are provided with the spline being slidably connected with rotating disc 16, first gear 13
Rotating disc 16 is driven to rotate, and then rotating disc 16 drives drive shaft 14 to rotate, drive shaft 14 drives first bevel gear 17 and second
Bevel gear 18 rotates simultaneously, and first bevel gear 17 drives third hand tap gear 19 to rotate, and third hand tap gear 19 drives the first rotary shaft
20 rotate, in the first rotary shaft 20 warp beam forward it is dynamic runs through the first screw mandrel 5, the first screw mandrel 5 is threaded with front plate 6, first
The first guide rail 21 being slidably connected with front plate 6 is fixed with rotary shaft 20, the first rotary shaft 20, which rotates, can drive front plate 6
Inwardly upset, second bevel gear 18 drive the 4th bevel gear 22 to rotate, and the 4th bevel gear 22 drives the second rotary shaft 25 to rotate, by
It is located at the both ends homonymy of drive shaft 14 in the bevel gear 22 of third hand tap gear 19 and the 4th, drive shaft 14 drives the in rotation process
Third hand tap gear 19 and the motion of the opposite direction rotating of the 4th bevel gear 22, first bevel gear 17 is identical with the size of second bevel gear 18, and the 3rd
Bevel gear 19 and the size of the 4th bevel gear 22 are also identical, so the rotational angle phase of the second rotary shaft 25 and the first rotary shaft 20
Together, but oppositely oriented, the second rotary shaft 25 drives the also inwardly upset of rear plate 10, and pedal 11 is adjusted to left movement
10 opposite flip-flop movement of front plate 6 and rear plate, reaches the pre- purpose stepped up；
When needing fine adjustments to clamp, ring gear is provided with first bevel gear 17, ring gear is engaged with to be rotatablely connected with bed body 1
Second gear 27, the gear 28 of 27 lower section external toothing of second gear the 3rd, the 3rd gear 28 be fixedly connected with and bed body 1 rotate connect
The handle 29 connect, pedal 11 can rotate to left movement with fixed handle 29, now, by original direction of rotation, rotate hand manually
Handle 29, handle 29 drive drive shaft 14 to continue to rotate by former direction, and rotating disc 16 is in the internal rotation of first gear 13, and first gear
13 are not rotated, and going barrel 36 is constantly being tightened up, and in first gear 13 in the presence of ratchet 15, can prevent drive shaft 14
Reverse, and can stop to be less than the diameter of drive shaft 14 to required position, the diameter of the 3rd gear 28, reach the mesh that stroke reduces
, more can effectively slow fine adjustments, it is at the end of running into emergency or checking, it is necessary to quick with more human nature care
Front plate 6 and rear plate 10 are opened, now adjusts shifting fork bar 24, rotating disc 16 is departed from first gear 13, sent out by shifting fork bar 24
In the presence of barrel 36, drive shaft 14 is reversed rapidly, drives the first rotary shaft 20 and the second rotary shaft 25 to reverse simultaneously, front plate
6 and rear plate 10 rapidly return back to elemental height, patient's can speeds away examination couch, convenient and swift, timely and effective, improves work
Make efficiency, when patient leaves backing plate 2 completely, push rod 33 departs from square groove, and motion bar 34 extrudes backing plate 2, and the position of backing plate 2 is not
Become, in the presence of the first spring 32, the 3rd rack 12 and pedal 11 rapidly return back to initial position, the first rack 3 and first
Partial gear 4 continues to engage, and the second rack 7 and the second partial gear 8 also continue to engage, and promotes push rod 33, push rod backward
33 the 3rd racks 12 of locking, motion bar 34 depart from backing plate 2, and backing plate 2 recovers to initial bit in the presence of second spring 23
Put, for backing plate 2 during rising, the first partial gear 4 drives the first screw mandrel 5 to return to initial position, the second incomplete tooth
The second screw mandrel 9 of drive of wheel 8 also returns to initial position, then adjusts shifting fork bar 24, rotating disc 16 and first gear 13 are nibbled again
Close.
The more traditional device of the present invention has following benefit：1）Using rack-and-pinion and screw structure, patient itself is utilized
Gravity, the opening distance of front plate and rear plate is automatically adjusted, automatically select suitably sized, convenient and swift, simple to operate, knot
Structure is ingenious；2）Using synchronous interaction mechanism, pedal can control front plate and rear plate to turn in opposite directions to during left movement
Turn to clamp, reach the purpose of pre- clamping, and can utilizes connecting rod gripping pad Board position, multiple functional；3）Emergent management is set to open
Closing, such as emergency, adjust shifting fork bar, rotating disc departs from first gear, in the presence of going barrel, front plate and rear folder
Plate, which is flipped back to rapidly, to be come, and is saved the time, is ensured patient safety；4）Structure is reduced using stroke, internal tooth is provided with first bevel gear
Circle, the 3rd gear diameter are less than ring gear, and handle rotates one week, and drive shaft turns reached fine adjustments fore-clamp less than one week
The purpose of plate and rear plate flip angle.
Clever structure of the present invention, it is convenient and practical, the time is saved, while link gear is used, and simple operation, the popularization of value,
There is very high potential value.
