Abstract
The utility model relates to a special mirror for preventing the light reflection of a blackboard, which comprises a special mirror body and is characterized in that the special mirror consists of a polaroid and an outer frame, wherein the plastic outer frame is inlaid around the polaroid. The utility model utilizes the characteristics of the polaroid for weakening the reflected light and inlays the square polaroid in the plastic outer frame, the appropriate angle can be easily found by rotating the special mirror, and the reflected light is weakened. The outer frame is thicker than the polaroid, the wear of the polaroid can be reduced, the service life of the polaroid can be prolonged, and the polaroid is portable, therefore, the purpose of simply and effectively eliminating the light reflection of the blackboard can be achieved.
Description
Technical field
The utility model relates to a kind of anti-blackboard reflective light specialized mirror.
Background technology
Blackboard reflective light is the big problem that the student is vexatious, teacher worries always, and it not only directly influences the effect that the student listens to the teacher, and also can cause damage to student's eyesight for a long time.The product that many elimination blackboard reflective lights are arranged now all is to do some to improve on blackboard basically, but all not really desirable on the effect of eliminating blackboard reflective light.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of anti-blackboard reflective light specialized mirror is provided, the elimination blackboard reflective light that it can be simple and effective.
For achieving the above object, the technical scheme that the utility model is taked is: described anti-blackboard reflective light specialized mirror comprises the specialized mirror body, it is characterized in that: described specialized mirror is made up of polaroid and housing, is provided with housing around the polaroid, and polaroid is set in the housing.
Described anti-blackboard reflective light specialized mirror is characterized in that, described polaroid is a square.
Described anti-blackboard reflective light specialized mirror is characterized in that described housing thickness is greater than the thickness of polaroid.
Described anti-blackboard reflective light specialized mirror is characterized in that described housing is plastic products.
The beneficial effects of the utility model are: for addressing the above problem, design of the present utility model is: utilize the characteristic of the diminished reflex light that polaroid has, polaroid is done quadrate, the rotation specialized mirror is easy to find suitable angle, diminished reflex light.Polaroid is set in the plastics housing, and so not only fixing polaroid can also prevent that polaroid from scratching hand, and hand-held position when being to use.Because housing ratio polarization sheet is thick, so can reduce wearing and tearing, make polaroid lengthening in serviceable life to polaroid, be easy to carry.Thereby reach the purpose of simple and effective elimination blackboard reflective light.The collimation mark high scale can also be worked as ruler and be used outside.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. polaroid; 2. housing.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: see Fig. 1, a kind of anti-blackboard reflective light specialized mirror comprises the specialized mirror body, it is characterized in that: described specialized mirror is made up of polaroid 1 and housing 2, is provided with housing 2 around the polaroid 1, and polaroid 1 is set in the housing 2.
Described anti-blackboard reflective light specialized mirror is characterized in that, described polaroid 1 is a square.
Described anti-blackboard reflective light specialized mirror is characterized in that the thickness of described housing 2 is greater than the thickness of polaroid 1.
Described anti-blackboard reflective light specialized mirror is characterized in that described housing 2 is plastic products.
During use, the hand-held housing of user is watched blackboard by polaroid, rotatory polarization sheet simultaneously, and when the direction of shaking thoroughly of polaroid is vertical with the polarization of reflected light direction, just can diminished reflex light and make letter written with chalk become clear.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
