Description
Technical field
The application relates to a kind of optical field device, particularly relates to a kind of light reflecting device.
Background technology
Just requisite thing in our daily life, in order to live conveniently, society is also with occurring in that many light sources, and from the torch of ancient times, oil lamp finally, electric light till now, this series of development is all along with the progress of society.And also have the things of the characteristic much using light in living, and being reflected in of light wherein occupies an important part.
Light has straightline propagation, follows the features such as the reflection law of light, the law of refraction.Middle school student have just contacted physics, just physics are produced keen interest, utilize conventional equipment to probe into the reflection law of light, and operation easier is high, and phenomenon is unstable, it is easy to allow student produce to be weary of sense.In order to student's distinctness, test presentation vividly, intuitively, bring while the more thinking of student is impacted and experience the basic of physics, it is necessary to have new exploration instrument to coordinate teaching.
Summary of the invention
For problems of the prior art, the utility model proposes a kind of light reflecting device, including the graduated tile 101 and the graduated tile 102 that are perpendicular to horizontal table top；Support 103 is arranged on after graduated tile 101 and graduated tile 102；Support 103 is provided with laser pen 104；Mirror 105 lies in horizontal table top, is close to graduated tile 101 and graduated tile 102.
Wherein, graduated tile 101 and graduated tile 102 are to separate, and can rotate along normal direction.
Wherein, support 103 includes cradling piece 1031 and cradling piece 1032, and laser pen 104 is installed on cradling piece 1032, and laser pen 104 is perpendicular to cradling piece 1032, parallel with cradling piece 1031.
Wherein, when cradling piece 1031 is perpendicular to horizontal table top, cradling piece 1032 is parallel to horizontal table top.
Wherein, support 103 is parallel to graduated tile 101 and graduated tile 102 rotates.
By this utility model, experimental performance can be improved, and achieve effect strong, practicality high obvious, detachable, repeated.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
It is illustrated in figure 1 the structural representation of this utility model light reflecting device.This light reflecting device includes the graduated tile 101 and the graduated tile 102 that are perpendicular to horizontal table top, and mirror 105 lies in horizontal table top, is close to graduated tile 101 and graduated tile 102.Graduated tile 101 and graduated tile 102 are to separate, and can rotate along normal direction.Support 103 is arranged on after graduated tile 101 and graduated tile 102.Support 103 is provided with laser pen 104.
Fig. 2 is the structural representation of support 103.Support 103 includes cradling piece 1031 and cradling piece 1032.Laser pen 104 is installed on cradling piece 1032.Laser pen 104 is perpendicular to cradling piece 1032, parallel with cradling piece 1031.
When cradling piece 1031 is perpendicular to horizontal table top, cradling piece 1032 is parallel to horizontal table top.
Fig. 3 is the top view of light reflecting device.Can be evident that by this figure, when cradling piece 1031 is perpendicular to horizontal table top, vertically, mirror 105 is placed on the centre position (having only to a part for mirror 105 in reality in middle position) of graduated tile 101 and 102 for cradling piece 1032 and graduated tile 101 and graduated tile 102.
Fig. 4 is another structural representation of light reflecting device.Support 103 is parallel to graduated tile 101 and graduated tile 102 rotates, such that it is able to change the angle of incident ray.
Likewise it is possible to rotate graduated tile 101 or graduated tile 102, allow two pieces of planks not in the same plane, be rotated further by plank and allow two pieces of planks in the same plane, contrast incident ray, reflection light, normal be whether in the same plane in.
Although describing this utility model by embodiment, skilled addressee will appreciate that, this utility model has many deformation and is varied without departing from spirit of the present utility model, it is desirable to appended claim includes these deformation and is varied without departing from spirit of the present utility model.
