There is diffuse-reflectance in photronic passage installing in light, causes part light can not arrive light cell and the error that causes, improve
The accuracy that rotary shaft rotational angle is detected.
Each embodiment that this utility model provides, at least has the advantages that
1, in this utility model embodiment, rotary shaft can rotate under the support of support, position correction apparatus and rotation
Axle is connected, and when rotary shaft rotates deviation equilbrium position under the driving effect of tested blood, promotes position correction apparatus
Produce the active force making direction, axial rotary equilbrium position rotate.So, when tested blood, the driving effect of rotary shaft is removed
After, if rotary shaft location is not equilbrium position, rotary shaft automatically reverts under the active force of position correction apparatus
Equilbrium position, it is not necessary to rotary shaft is calibrated by the mode manually regulated, saves the time calibrating rotary shaft, carries
The high efficiency that blood blood clotting is detected.
2, in this utility model embodiment, position correction apparatus can include at least one hairspring spring, hairspring spring
Inner ring is fixing with rotary shaft to be connected, and the outer ring of hairspring spring is fixing with support to be connected, when rotary shaft rotates deviation equilbrium position
Making hairspring spring deform, the elastic force that hairspring camber of spring produces acts in rotary shaft, and the action direction of this elastic force is for making
Rotary shaft recovers the direction to equilbrium position.Owing to hairspring spring-mass is relatively light and it is quick on the draw, using hairspring spring as position
Put correcting unit and can reduce the resistance received when selecting the inertia of axis and rotate, improve the accuracy of thrombosis elastometer.
3, in this utility model embodiment, position correction apparatus can include multiple hairspring spring, in all hairspring springs
The hand of spiral of a part of hairspring spring is contrary with the hand of spiral of other hairspring springs, and the direction making axial rotary different rotates
Shi Jun has part hairspring spring to be tightened, and such structure can extend the service life of hairspring spring, and ensures rotary shaft energy
Enough rotations smoothly.
4, in this utility model embodiment, hairspring spring is fixed with support by zeroing module, zeroing module and hairspring
The link position of spring outer ring can regulate, thus by the link position of regulation zeroing module and hairspring spring outer ring to rotation
Shaft balancing position is adjusted, and calibrates with the equilbrium position to rotary shaft, improves the ease for use of thrombosis elastometer.
5, in this utility model embodiment, by jewel bearing and addendum cone phase between fixed support portion with moveable support portion
Even, it is connected for point between jewel bearing with addendum cone, owing to contact area is less, produces when jewel bearing and addendum cone relatively rotate
Frictional force is less, thus the resistance that support rotates generation to rotary shaft is relatively small, thus rotary shaft can be in less driving
Just can rotate under power, improve susceptiveness and the accuracy of thrombosis elastometer.
6, in this utility model embodiment, by the rotational angle of optical signal detecting rotary shaft, due to stablizing of optical signal
Property, do not affected by factors such as temperature, compared by the rotational angle of resistance detection rotary shaft relative to prior art, Ke Yiti
The high accuracy detecting rotary shaft rotational angle, is further ensured that the accuracy of blood Blood coagulation test.
