During rotation, the direction of motion at U-shape structure lower-left end end points (B) of crank (07) is vertical with ray OA, and the translation of sliding block (04) is
The higher-order shear deformation of U-shape structure lower-left end end points (B) motion of crank (07), this has been effectively ensured temperature-changeable calibration blackbody component
(01) switching precision and stability in place.
5. the temperature-changeable calibration blackbody component quick switching mechanism of infrared light path is used for as claimed in claim 1, and its feature exists
In the power supply of temperature-changeable calibration blackbody component (01) is the contact (14) of the touch article (13) by touch article plate (03) and contact board (05)
Elastic connection is realized；
Described touch article (13) one end screw is fixed on touch article plate, and touch article (13) other end is the contact block with circular arc, touch article
(13) center section is the elastic piece structure of Bao Erchang；
The contact (14) is the contact block structure with circular arc；The touch article (13) and the confession of temperature-changeable calibration blackbody component (01)
Electric end conducting, the contact (14) turns on external cable；
In when cutting out optical path states, the contact block part with circular arc of touch article (13) is located at temperature-changeable calibration blackbody component (01)
Contact (14) top, the now certain amount of elastic deformation in the middle shell fragment part of touch article, the amount of elastic deformation can cause touch article
(13) there is certain precompression and contact (14) between, and then cause the power supply of external cable and temperature-changeable calibration blackbody component (01)
The reliable conducting in end, realizes function of supplying power, this avoids service cable connection of temperature-changeable calibration blackbody component (01), it is to avoid electricity
Influence of the cable to switch speed, improves switch speed.
