Description

Technical Field

[0001] The invention belongs to the technical field of teaching stationery, office supplies and myopia prevention and control, and specifically relates to a zoom mirror, in particular to a reading zoom mirror used for learning. Background Art

[0002] There are many kinds of myopia prevention and control glasses on the market, each with its own advantages. Among them, some telescope glasses place two roughly parallel mirrors, one convex and one concave, between the chest and the book to form a fog screen, which can prevent people from lowering their heads and blocking them from approaching the book, which is equivalent to doubling the distance between the two mirrors. However, it also blocks the eyes, making it inconvenient to look at the book under the mirror and turn the pages. There are also telescope glasses that use the principle of AI glasses to place the electronic screen flat on the bottom and rely on a semi-transparent and semi-reflective mirror and a curved reflector to form a telescope fog screen. The oblique semi-transparent and semi-reflective mirror is used to reflect the bottom display screen through the upper oblique semi-transparent and semi-reflective mirror to the concave mirror in front, where it is magnified and then reflected back to the front of the eyes through the semi-transparent and semi-reflective mirror. The display screen under the semi-transparent and semi-reflective mirror can be zoomed out and imaged, but the cost is relatively high. Some people place a baffle on the desk. The baffle is placed in front of the chest to prevent the body from leaning forward and prevent the eyes from being too close to the book, so as to keep a certain distance when reading. However, there is also the problem of inconvenience in learning with obstacles in front. Summary of the invention

[0003] The present invention aims to overcome the shortcomings of the above-mentioned technologies and provide a reading telescope that can bring the image of a book to a farther distance. The telescope can be placed opposite a desk, without blocking the front of the body, and does not hinder learning and writing, making it more convenient to use.

[0004] The technical solution of the present invention is achieved in this way: A reading zoom mirror mainly comprises a front reflector, an upper reflector and a bracket, and is characterized in that: the front reflector is tilted with its reflective surface facing obliquely upward, the reflective surface of the front reflector faces the reader and is tilted upward, the upper reflector is placed above the front reflector with its reflective surface facing downward, and the front reflector and the upper reflector are supported externally by the bracket.

[0005] The aforementioned reading telescope can form a reading telescope reflective light path. A reading material is placed in front of and below the reader, an upper reflector is arranged above the reading material, and an inclined front reflector is arranged in front of and below the upper reflector. The reading material placed in front of and below the reader diffusely reflects light upward to the upper reflector, then reflects it to the inclined front reflector placed in front and below, and then reflects it to the reader's eyes through the inclined front reflector.

[0006] Furthermore, the front reflector and the upper reflector are both plane mirrors.

[0007] Furthermore, the front reflector and the upper reflector are both concave mirrors.

[0008] Furthermore, the front reflecting mirror is a concave mirror, and the upper reflecting mirror is a plane mirror.

[0009] Furthermore, the front reflecting mirror is a concave mirror, and the upper reflecting mirror is a convex mirror.

[0010] Furthermore, the angles of the front reflector and the upper reflector can be adjusted.

[0011] Furthermore, the height and position of the front reflector and the upper reflector can be adjusted.

[0012] Furthermore, the front reflector is placed at an appropriate angle of 30-60 degrees to the horizontal plane, with the reflective surface facing the reader.

[0013] Furthermore, the upper reflector is placed at an appropriate angle of 0-30 degrees to the horizontal plane, with the reflective surface facing downwards towards the reading object.

[0014] Furthermore, the front reflector 1 is hingedly connected to one side of the upper reflector 2 via a connecting rod 5 .

[0015] Furthermore, the bottom of the bracket is a C-shaped base and a locking rod, the base is connected to the column, the column is slidably connected to a connecting block, a horizontal axis is arranged in the horizontal hole of the connecting block, connecting rods are arranged at both ends of the horizontal axis, the middle part of the connecting rod is connected to the front reflector, and the upper part of the connecting rod is connected to the upper reflector.

[0016] Furthermore, the bottom of the bracket is a writing board, which is hingedly connected to the outer frame of the front reflector through a hinge, the upper part of the outer frame of the front reflector is hingedly connected to the connecting rod through a hinge, and the upper part of the connecting rod is hingedly connected to the outer frame of the upper reflector through a hinge.

[0017] Furthermore, the aforementioned sliding adjustment method can also be a rocker arm connection method of an articulated multi-link, which can be moved to a desired position at will and then locked. Beneficial Effects

[0018] Compared with the prior art, the beneficial effects of the reading telescope of the present invention are: 1. Image zooming. The front reflector is placed opposite the desk, with the book in between. The reflective surface of the front reflector faces the reader and is tilted upward. The distance from the eyes can be more than 50 cm. The distance between the upper reflector and the reading object can also be more than 40 cm. In addition, the distance between the two reflectors can be more than 20 cm. The total optical path length can exceed 1 meter. Even if the front reflector and the upper reflector are both plane mirrors, the book can be zoomed out to 1 meter for reading, which is three or four times farther than the distance of direct reading with the eyes, and can avoid long-term close-up viewing. If a concave mirror is added to magnify and zoom out, the zoom distance can be further.

[0019] 2. No obstruction. The reading telescope is placed opposite the desk. There is no obstruction in front of the book, and there is no obstruction to writing, which is more convenient to use.

[0020] 3. Save space. The reading telescope is placed opposite the reader, takes up less space and rarely occupies the user's writing position. It can be placed opposite the desk at home or the desk in the classroom.

[0021] 4. Reading posture is more correct. You don’t need to lower your head too much when reading. You can look up and forward over the book to prevent damage to the cervical spine.

[0022] 5. Easy to use. The writing board 14 as the base of the bracket 10 can be moved anywhere, and can be placed anywhere other than the desk. The area where the writing board 14 is placed is the reading area, and the books and reading materials placed on it can be pulled away by the front reflector 1 and the upper reflector 2 to read 1 meter away. It can be folded and stored when not in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] For ease of explanation, the structure and principle of the present invention are described below by taking a desk reading telescope as an example.

[0027] like Figure 1 As shown, the present invention discloses a reading zoom mirror, the main optical components of which are a front reflector 1 and an upper reflector 2. A bracket 4 is arranged at the bottom of the front reflector 1 and the upper reflector 2, and the bracket 4 is hingedly connected to the front reflector 1 and the upper reflector 2 through a connecting rod 5. The front reflector 1 is placed obliquely, with the reflecting surface facing the reader and obliquely upward, facing the upper reflector 2, and the upper reflector 2 is placed directly above the front reflector 1 with the reflecting surface facing downward, aiming at the reading area. The front reflector 1, the upper reflector 2 and the connecting rod 5 are supported on the desktop by the bracket 4, and the plane area below the reading zoom mirror and the reader is the reading area.

[0028] like Figure 1 As shown in the figure, it is a distance reading optical path. Reading materials such as teaching materials, books, test papers, etc. are placed in front of the reader. An upper reflector is set above the reading material, and an inclined front reflector is set in front of and below the upper reflector (away from the reader). The reflective surface faces the reader's eyes 5. The book is placed on the table reading area, and the angles of the upper reflector and the front reflector are adjusted according to the position shown in the figure. The light 4 diffusely reflected by the book or other reading material propagates upward from point A, is reflected by point B of the upper reflector 2 above to the inclined front reflector 1 below, and then is reflected by point C of the inclined front reflector 1 to point O of the reader's eyes 6. After two reflections by the upper reflector 2 and the front reflector 1, the object image will form an image consistent with the reading direction, or an image that stands up in the reading direction, and a front view image parallel to the reader's body, just like looking at a computer display screen. The total optical path length is AB+BC+C0, which is more than 3 times longer than the optical path length OA of the eye 6 directly viewing the reading material 3, which increases the reading distance and turns near into far.

[0029] like Figure 2 As shown, the present invention discloses a sliding bracket structure, and the angle at which the front reflector 1 is placed can be reasonably adjusted according to actual conditions. The bottom of the bracket 10 is a C-shaped base 7 and a locking rod 12 fixed to the front side of the desk 9, the base 7 is fixedly connected to the column 11, and the column 11 is slidably connected to the connecting block 13, the vertical hole of the connecting block 13 can slide up and down the column 11 and can be locked anywhere, a slidable horizontal axis 8 is set in the horizontal hole of the connecting block 13, and connecting rods 5 are set at both ends of the horizontal axis 8, the middle part of the connecting rod 5 is connected to the front reflector 1, and the upper part of the connecting rod 5 is connected to the upper reflector 2.

[0030] like Figure 3 As shown, the present invention discloses a writing board with a hinged bracket reading telescope structure, and the angle at which the front reflector 1 is placed can be reasonably adjusted according to actual conditions. The bottom of the bracket 10 is a writing board 14, and the upper area of ​​the writing board 14 is a reading area. The boundary of the reading area can be drawn for easy use, and the books placed at the boundary of the reading area can be read by the front reflector 1 and the upper reflector 2. A4 paper or reading material 3 can be placed in the reading area. The writing board 14 is hingedly connected to the outer frame of the front reflector 1 through a hinge 15, and a concave mirror is fixedly placed in the outer frame of the front reflector 1. There are two hinges 15, which are respectively connected to the front of the writing board 14 and the bottom of the outer frame of the front reflector 1. The upper part of the outer frame of the front reflector 1 is hingedly connected to the connecting rod 5 through the hinge 15, and the upper part of the connecting rod 5 is hingedly connected to the front of the outer frame of the upper reflector 2 through the hinge 15. A concave mirror is fixedly placed in the outer frame of the upper reflector 2. Bolts, nuts and butterfly washers are arranged in the damping hinges 15 at various locations, so that the angles can be twisted at will, and the damping hinges 15 can be locked at any location after being rotated to a suitable angle.

[0031] To reduce costs, a plane mirror may also be placed inside the outer frame of the upper reflector 2 .

[0032] The angles of the front reflector 1 and the upper reflector 2 can be adjusted and fixed after adjustment. The most suitable angle position of the front reflector 1 is 30-60 degrees with the horizontal plane, and can reach within 80 degrees in extreme cases, with the reflective surface facing the reader and the upper reflector 2 in the front and upper part; the most suitable angle position of the upper reflector 2 is 0-30 degrees with the horizontal plane, and can reach within 45 degrees in extreme cases, with the reflective surface facing downward, slightly inclined toward the front reflector 1, and facing the reading area. The front reflector 1 and the upper reflector 2 preferably form an angle of 30-60 degrees with each other.

[0033] The front reflector 1 and the upper reflector 2 are both plane mirrors, and the front coated reflector is preferably used to avoid the ghosting phenomenon of glass mirrors.

[0034] The front reflector 1 may be a concave mirror in addition to a plane mirror, and the upper reflector 2 may be a concave mirror or a convex mirror in addition to a plane mirror.

[0035] The front reflector 1 and the upper reflector 2 which are plane mirrors, concave mirrors or convex mirrors may be used in combination.

[0036] like Figure 1 As shown, the front reflector 1 and the upper reflector 2 are both plane mirrors. Because the optical path is long, the length can exceed one meter, and the plane mirror can be used to pull books and other reading materials from a distance of one foot to a distance of 1 to 2 meters.

[0037] In addition to the plane mirror, one application scenario is that both the front reflector 1 and the upper reflector 2 are concave mirrors. Through the magnification and telescoping effect of the two concave mirrors, the image can be zoomed out to five, six or ten meters, allowing for magnification and long-distance reading.

[0038] Another application scenario is that the front reflector 1 is a concave mirror and the upper reflector 2 is a plane mirror, which can magnify close-up reading materials such as books and pull them to a farther distance, which can be pulled to five meters away, so that they can be magnified and read at a long distance.

[0039] The front reflector 1 and the upper reflector 2 are one convex mirror and one concave mirror. For example, the front reflector 1 is a concave mirror, which has a magnifying effect and obtains a large field of view. The upper reflector 2 is a convex mirror, which makes the reading area larger and allows more reading materials to be seen. The combination of the two can obtain a larger field of view and a larger reading area, achieving the effect of magnifying the reading material and zooming out the reading material.

[0040] In order to obtain a convenient reading area, the angles of the front reflector 1 and the upper reflector 2 can be adjusted. The front reflector 1 and the upper reflector 2 are hingedly connected to the bracket 10 through a connecting rod 5 and can be rotated to an angle convenient for reading and then locked.

[0041] The front reflector 1 and the upper reflector 2 can be slidably connected to the connecting rod 5 and the bracket 10, and can be slidably adjusted to a height that is convenient for reading. The angle and height position can be adjusted.

[0042] The aforementioned sliding adjustment method can also be a hinged multi-link rocker arm connection method, which can be moved to the required position and then locked, and will not be described in detail with reference to the drawings.

[0043] The front reflector 1 and the upper reflector 2 of the writing board 14 are hingedly connected to each other at one side and can be folded. The front reflector 1, the upper reflector 2 and the bracket 10 are folded together for easy carrying and storage.

[0044] A telescopic rod is installed at the bottom of the aforementioned writing board 14, and a book pressing board is arranged on the upper surface, which can be used as a reading platform with a reading telescope.

[0045] An illuminating lamp may be arranged above the bracket 10 to illuminate the reading area and improve the light environment of the reading area.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
