Abstract
The utility model provides a tooth color comparator. The tooth color comparator is characterized in that the utility model is composed of a detector and a display part. The detector is provided with a pen-shaped casing. The inner part of the pen-shaped casing is coaxially provided with a light source, a light-guiding lens and a photoresistor. The light source is fixed at the tail of the detector. The front end of the light source is provided with the cylindrical light-guiding lens which is provided with blind holes. A coaxial self-reflective optical system is formed bu the light source and the light-guiding lens. The photoresistor is fixed in the blind holes arranged at the front end of the light-guiding lens. The side wall and the bottom part of the blind holes are respectively fixed with a light-tight optoisolator and a rubber pad. The lead wire of the photoresistor is connected with the display part. The tooth color comparator uses digital display to replace the past observation by human eyes so that detection comparative accuracy is raised.
Description
This utility model relates to a kind of tooth colourity comparator block that is used to observe tooth colourity.
Adopt eye-observation relatively to the observation of tooth colourity in the medical practice at present, the comparative result degree of accuracy is low, and effect is bad.
Task of the present utility model is a kind of tooth colourity comparator block of design, can observe comparison tooth colourity more accurately.
This utility model is achieved by the following scheme: design a kind of tooth colourity comparator block, it is made of survey meter and display part, wherein coaxial device light source in the form of a stroke or a combination of strokes shell of survey meter, light guiding lens and photoconductive resistance, light source is fixed in the survey meter afterbody, the light source cylindrical light guiding lens preceding with being fixed in light source forms coaxial from reflective optical system, on the light guiding lens front end face, have one with the co-axial blind hole of lens, the blind hole internal fixation has photoconductive resistance, blind hole medial surface and bottom are being fixed lighttight optoisolator and rubber blanket respectively, penetrate photoconductive resistance with end face from the side to prevent light.The photoconductive resistance lead-out wire is connected with the display part, and the display part is formed, surveyed comparative result to show by amplifier, A/D converter and display.
The utility model has the advantages that and adopted optical detection and digitized to show, reduced the error that eye-observation in the past causes, improved and surveyed precision relatively.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, probe body (6) is the form of a stroke or a combination of strokes, the light source of its tail end (7) forms coaxial from reflective optical system with the long column shape light guiding lens (5) of light source front, have blind hole at light guiding lens (5) front surface, the reflected light of measured object is received by photoconductive resistance (2) by blind hole, photoconductive resistance lead-out wire (4) is connected with the display part, for preventing that side and end face light from penetrating photoconductive resistance (2), fix optoisolator (1) at the blind hole medial surface, be provided with lighttight rubber blanket (3) in the blind hole bottom surface.Described photoconductive resistance (2) is the CDS photoconductive resistance.
Claims (3)
1, a kind of tooth colourity comparator block, it is characterized in that: this instrument is made up of survey meter and display part, wherein the interior coaxial arrangement of form of a stroke or a combination of strokes shell (6) of survey meter has light source (7), light guiding lens (5) and photoconductive resistance (2), described light source (7) is fixed in the survey meter afterbody, columniform light guiding lens (5) is being fixed in the light source front portion, one and the co-axial hole of educating of lens are arranged on the front end face of light guiding lens (5), this is educated the medial wall, hole and is fixed with optoisolator (1), the blind hole bottom is a lighttight rubber blanket (3), photoconductive resistance (2) is being fixed in the front of rubber blanket (3), and photoconductive resistance lead-out wire (4) passes rubber blanket (3) and is connected with the outer display part of light guiding lens (5) and survey meter.
2, according to the described tooth colourity of claim 1 comparator block, it is characterized in that: the display part is made up of amplifier, A/D converter and display.
