Description

Shading box for tongue diagnosis instrument

Technical Field

The utility model relates to a tongue diagnosis instrument in the traditional Chinese medicine diagnosis, in particular to a shading darkroom structure for assisting the image acquisition of the tongue diagnosis instrument.

Background

The tongue diagnosis is one of the traditional Chinese medicine diagnosis methods, and the tongue diagnosis instrument is a traditional Chinese medicine diagnosis device which introduces an image recording and processing technology into tongue diagnosis and is used for judging possible causes of the patients by shooting tongue images of the patients and comparing the tongue images with standard tongue images in aspects of color, texture, form and the like.

The tongue diagnosis instrument is used for completely and clearly recording the tongue image of a patient, and the most common factor influencing the image quality is ambient light, so that a space which is slightly influenced by the ambient light is required to be created, and the influence of the ambient light on image shooting is reduced. The existing tongue diagnosis equipment basically has a set of structure similar to a darkroom, but due to the consideration of volume or portability during design of manufacturers, the shading effect of the structure is not good, and on the other hand, a patient is difficult to keep the posture when facing the instrument, so that the consistency of tongue image shooting is poor.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the shading box of the tongue diagnosis instrument is provided, the influence of ambient light on tongue image shooting is reduced, and the shading box is convenient for a patient to use and cooperate and adjust.

The technical scheme of the utility model as follows:

the tongue diagnosis instrument shading box comprises a shading box body with open front and back end surfaces and closed upper, lower, left and right end surfaces, wherein a jaw support, a shading plate with light holes and a luminous source are sequentially arranged in the shading box body and at the front end surface from outside to inside;

a shading plate notch is formed in the left or right end face of the shading box body;

the jaw support is detachably connected with the lower end face of the shading box body;

the luminous sources are distributed along the contour line of the vertical section of the shading box body;

the contour of the light hole on the shading plate comprises an upper section of curve and a lower section of curve with different curvature radiuses, one side end of the shading plate is connected with the handle, and the shading plate is provided with a hanging hole.

Two ends of the jaw support are respectively connected with the two screw rods.

The screw rod comprises a thread section and a smooth section, and the smooth section is arranged in an inner hole of a fixing ring on the lower end face of the shading box body.

The luminous source is a continuous LED light band with closed heads and tails.

The utility model has the advantages of it is following: the light emitting source is arranged behind the shading plate and distributed along the outline line of the shading box body, so that consistent shooting background light can be provided, and the influence of partial ambient light on shooting can be reduced. The upper, lower, left and right end faces of the shading box body are made of shading materials (such as shading plates), the size of the shading box body can be selected according to actual requirements, and the shading box body is simple to manufacture. The openings of the front end face and the rear end face can respectively correspond to a patient and shooting equipment, so that the whole shooting process is controlled to be completed in the shading box body, and the influence of ambient light is avoided; the light shading plate is provided with a light hole for a patient to extend the tongue out and then enter a shooting area with a specific size outline, the outline of the light hole comprises an upper section of curve and a lower section of curve with different curvature radiuses, the upper section of curve corresponds to the outline of an upper lip, the lower section of curve corresponds to the outline of the extended tongue, as the distance between the jaw support and the light shading plate is fixed, as long as the patient extends the tongue into the light hole, the focusing is basically fixed, and the rest part of the light shading plate blocks ambient light from entering the light shading box body; the jaw support provides support for the patient, and it adopts the screw rod to support in shading box, and jaw support height accessible screw thread section is adjusted from top to bottom. The smooth section at the lower end of the screw rod can be directly inserted into the inner hole of the fixed seat and can be directly pulled out, and the jaw support can be detachably connected.
