According to the laser pointer type current meter structure, a laser beam is used as a pointer of a current meter instead of an entitative pointer, so that an effect of an extremely large scale disk which cannot be realized by the conventional entitative pointer type current meter can be achieved; and the shortcoming of low respond speed of deflection with the fast change of the measured current due to a large rotational inertia of the conventional entitative pointer is overcome.
Description
Technical field
The present invention relates to current instruments, adopt the pointer of laser beam as reometer.
Background technology
Pointer reometer now; The pointer that an entity is all arranged; But because the entity pointer has moment of inertia (inertia), thus the entity pointer can not do oversize, thereby the range of size of the index dial of reometer is done greatly; Even the reometer of not oversize entity pointer also can not and respond with electric current variation fast owing to the intrinsic moment of inertia of entity pointer makes the indication of reometer fast.
Summary of the invention
The object of the invention is exactly the deficiency that overcomes entity pointer-type reometer, and providing does not need the entity pointer, and adopts the structure of laser beam as the reometer of pointer.
The technical solution adopted for the present invention to solve the technical problems is: a kind of laser pointer reometer structure; Comprise the reometer housing; The inner face of reometer housing is provided with the curved scale line, under the home position that the curved scale line is corresponding deflection mechanism is installed, and the deflection coil of deflection mechanism is connected with the wiring pile crown of reometer housing bottom through the hairspring of upper-lower position; It is characterized in that; Said curved scale line has window directly over the center, and the window installed inside has laser head, and laser head is over against the yawing axis of deflection mechanism; Be fixed with the minute surface reflector on the deflection mechanism, and the axis of minute surface reflector reflective surface and the yawing axis of deflection mechanism are on the same straight line.
With a laser head be installed in reometer scale mark center directly over; A minute surface reflector is installed on the deflection mechanism of reometer; The minute surface reflector can rotate around the deflection mechanism of reometer with the current value of measuring, and the laser beam that laser head sends just faces the minute surface reflector; Shine the thin narrow laser beam of minute surface reflector, reflect through the minute surface reflector on the scale mark that projects reometer; The measurement deflection mechanism of the measurement deflection mechanism of laser pointer reometer and entity pointer reometer now is identical; Therefore the deflection angle of minute surface reflector is directly proportional with current value through reometer; According to the minute surface reflector reflection of light is presented the characteristic that incident angle equals reflection angle; The deflection angle of laser beam on scale mark that reflects on the scale mark that projects reometer also just is directly proportional with current value through reometer; Rest on the scale value on the scale mark through reading the laser light reflected bundle, just indicated the current value that flows through reometer.
Said scale mark top is provided with curved baffle, and window is opened in the center of curved baffle, and laser head is installed in the reometer housing of curved baffle opposite side, and the Laser emission mouth of laser head is the inclined that dips down over against the setting of minute surface reflector.
Said laser head is connected with direct supply.
The invention has the beneficial effects as follows: (1), because laser pointer does not receive length restriction, the scale mark of laser pointer table can be bigger 2 times than the scale mark of entity pointer---and 50 times (even bigger) especially conveniently is used for the demonstration of electrotechnical, electronic teaching.
(2), laser pointer is fast more than the entity speed of finger with the deflection of tested electric current response, can respond the quick variation of tested electric current as quick as thought.
(3), because the deflection angle of folded light beam is the twice of minute surface reflector deflection angle; Reflector only needs the deflection miter angle, and it just can make folded light beam deflection an angle of 90 degrees, therefore; After changing an entity pointer gauge into laser pointer; Just can the sensitivity of former pointer gauge be improved 1 times, maybe can former pointer gauge scale mark be extended 1 times, thereby make more highly sensitive reometer.
(4), can to repack multimeter into the same with entity pointer reometer; The laser pointer reometer also can be made the laser pointer multimeter very easily, behind adjunction sensing element on the reometer circuit, can also make the laser pointer formula measurement instrument of measuring any other physical quantity.
