Abstract
A viewing axis rotating observation mirror belongs to a pair of glasses and comprises mirror legs and lenses, wherein the lenses comprise baffles and glass lenses, the sections of the baffles and the glass lenses are right-angled triangles, the horizontal right-angled sides are provided with silver coatings, and the mirror legs are provided with hinge shafts. The utility model discloses can make the people when lying, watch TV or observe, the image is clear, convenient to use, is particularly suitable for patient or the old person who lies in bed to use.
Description
Technical field:
The utility model relates to a kind of daily living article, is a kind of glasses of changeable angle specifically.
Background technology:
At present, the function of common spectacles is mainly corrected defects of vision, light changes focal length by eyeglass and enters eyeball, and human eye is that straight line is seen object basically, but in actual life, the people needs to change angle sometimes and observes object, as some patient and the elderly, things in when bed of lying low can't observation ward more can't be seen TV, easily make people's fatigue and raise head, thereby their life has many inconvenience.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, thereby a kind of optical axis rotation sight glass is provided, and makes the people also can see the image of normal observation when lying low.
The purpose of this utility model realizes in the following way:
This optical axis rotation sight glass is made up of mirror holder (1), mirror leg (2) and eyeglass (3), wherein eyeglass (3) is made up of baffle plate (5) and glass lens (6), the rectangular triangle in baffle plate (5) cross section, short right-angle side is being attached on the mirror holder (1), long right-angle side level is located at the upper end, and its inboard has silver coating (7), glass lens cross section (6) also rectangular triangle, be embedded in baffle plate (5) inboard, both ends of the surface are covered by baffle plate.
The acute angle of glass lens (6) front end is 30 °.
Mirror leg (2) can be divided into two joints, is connected by hinge (8).
During use, putting on one's glasses lies low, and light and level are 30 ° of angles to be injected, and enters human eye after twice refraction, and the people can see upright image, and that stands up with not wearing glasses and see is the same.
The utility model compared with prior art has following advantage:
For the elderly of patient or bed, can see TV at an easy rate when lying low or observe that clear picture is correct, the time spent can be by the hinge eyeglass that overturns, and is easy to use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model front view;
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the A-A cut-open view of Fig. 1.
In Fig. 1: 1, mirror holder; 2, mirror leg; 3, eyeglass; 4, hinge; 8, hinge.
In Fig. 3: 5, baffle plate; 6, glass lens; 7, silver coating.
Embodiment:
See Fig. 1: the utility model is made up of mirror holder (1), mirror leg (2) and eyeglass 3, eyeglass 3 is made up of baffle plate (5) and glass lens (6), the rectangular triangle in baffle plate (5) cross section, and short right-angle side is attached on the mirror holder (1), long right-angle side level is located at the upper end, its inboard has silver coating (7), and glass lens (6) is a triangular prism, the rectangular triangle in cross section, be embedded in baffle plate (5) inboard, can be bonding, both ends of the surface are covered by baffle plate, and the front end acute angle is 30 °.Shown in Fig. 2, glass lens be can't see in both sides, in Fig. 3, it shown in the arrow radiation direction, light enters glass lens (6) from external vertical, after the inboard silver coating (7) of baffle plate (5) is gone up reflection, carries out a total reflection again to the lens hypotenuse, penetrate from lens right-angle side one end level, enter human eye.Lens glass adopts optical glass, and refractive index is between 1.5～1.6.
Claims (3)
1, a kind of optical axis rotation sight glass, form by mirror holder (1), mirror leg (2) and eyeglass (3), it is characterized in that: eyeglass (3) is made up of baffle plate (5) and glass lens (6), the rectangular triangle in baffle plate (5) cross section, short right-angle side is being attached on the mirror holder (1), and long right-angle side level is located at the upper end, its inboard has silver coating (7), the also rectangular triangle in glass lens cross section (6) is embedded in baffle plate (5) inboard, and both ends of the surface are covered by baffle plate.
2, optical axis rotation sight glass according to claim 1, it is characterized in that: the acute angle of glass lens cross section (6) front end is 30 °.
