The utility model mainly comprises a first reflector and a second reflector in front of eyes, and articles to be observed such as textbooks and the like on a table top are reflected by the first reflector and then reflected into the eyes by the second reflector, so that people can see the articles to be observed when the sight lines are basically horizontal or slightly declined, the head of a human body is basically kept in a natural state, and the head does not need to be lowered or raised relative to the body, thereby relieving the fatigue of cervical vertebra; the first reflector is used for reflecting once, so that the image of the textbook is observed in human eyes as a positive image, and the relative direction of the image of the textbook is consistent with the relative direction of the observed object observed by a person when the person lowers the head, so that the writing is convenient, and the user does not feel inverted during writing.

Description

Desktop reading and writing auxiliary system

Technical Field

The utility model relates to the technical field of reading and writing assistance, in particular to a desktop reading and writing assistance system.

Background

At present, the general pressure of education is very large, the homework of primary school students is very much, and the students spend the main time of a day in front of a desk, so that the problems of hunchback, myopia and cervical vertebra of children are caused. There are many products to solve this problem. For example, various height-adjustable seats, children's study desks, and even the inclination of the plane of the panel on the desk can be adjusted, which is very beneficial for children to study. In addition, there are various auxiliary devices for correcting sitting posture. For example, various body straps for correcting posture such as "excellent back". Various devices that prevent myopia and kyphosis in addition, generally form in front of children's body and shelter from the obstacle for children can't bend over to lie prone on the desk, thereby reach the function of prevention myopia and kyphosis.

At present, all devices for correcting postures cannot completely solve all problems, particularly when the posture is correct, books are firmly arranged at the low position in front of the chest of a child, so that the head of the child is bound to look downwards under the condition that the upper body of the child is straight, eyes are natural, the cervical vertebra is bound to bear larger pressure, cervical spondylosis is bound to be caused in a long term, if the head and the cervical vertebra of the child are kept natural, the child is bound to bend over to see the books, humpbacks are easy to cause, a method for inclining a desktop is adopted for some writing tables, the inclination is very limited, and the books cannot slide down to be stably placed at any position due to too large inclination, and the writing is not bound to be written on a horizontal plane conventionally.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a desktop reading and writing auxiliary system, which solves the problems in the background technology.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a desktop reading writing auxiliary system, includes people's eye, speculum group and desktop to and place the reading writing thing on the desktop, still be equipped with speculum group on the desktop, and the braced system that associates with speculum group, speculum group comprises first speculum and second speculum.

Optionally, the first reflecting mirror and the second reflecting mirror are both in a plane or curved surface structure, the first reflecting mirror is vertically arranged on the desktop, and the second reflecting mirror is obliquely arranged on one side of the first reflecting mirror.

Optionally, the first reflecting mirror and the second reflecting mirror are both planar or curved structures, and both the first reflecting mirror and the second reflecting mirror are obliquely placed on the desktop.

Optionally, the first reflecting mirror is arranged on the table top, and the first reflecting mirror is higher than and above the second reflecting mirror which is obliquely arranged.

Optionally, the second reflecting mirror is obliquely arranged above the first reflecting mirror, and an extension line of the first reflecting mirror and the extension line of the second reflecting mirror form an obtuse angle.

The utility model provides a desktop reading and writing auxiliary system, which has the following beneficial effects:

1. the utility model aims to solve the problem that the sight of a normal sitting posture is not horizontal to a book in long-term writing, so that the burden of cervical vertebra is too heavy when a person bends over the head; the utility model adopts the form of reflection of at least two optical reflection lenses to image books and the like originally placed on a desktop at the positions where the sight lines of human eyes are basically horizontal, and the books are written to form positive images, thereby facilitating reading and writing of people; further, through speculum or extra lens, produce focusing effect, image into books in the front of people's eye more distant place, for example one meter is outer and keep the visual angle of image pair people's eye unchangeable, not only effectively alleviate the problem that the eyes focus for a long time when reading and are too close easily near, but also can relax the children that have myopia, resume eyesight, simultaneously can also trade books into the view picture of high resolution or the picture that beneficial eyesight resumes, relax children or user's the eye of writing for a long time reading, resume.

2. The desktop reading and writing auxiliary system mainly comprises a first reflector and a second reflector in front of human eyes, observed objects such as textbooks and the like on a desktop are reflected by the first reflector and then reflected into the human eyes by the second reflector, so that people can see the observed objects when the sight lines are basically horizontal or slightly declined, the head of a human body is basically kept in a natural state, and the head does not need to be lowered or raised relative to the body, so that the cervical vertebra fatigue is relieved; the first reflector is used for reflecting once, so that the image of the textbook is observed in human eyes as a positive image, and the relative direction of the image of the textbook is consistent with the relative direction of the observed object observed by a person when the person lowers the head, so that the writing is convenient, and the user does not feel inverted during writing.

3. The reflecting mirror can be a plane mirror or a curved mirror, and can generate a zooming effect and an imaging position adjusting effect on the finally observed image of the eyes; the accommodation function means that the image formed by the relative eyes is placed at a relatively far distance, even infinity, so that the eyes are in a relatively relaxed position during observation, and the lens does not need to be adjusted, thereby playing a role in protection; the imaging can be placed at a close distance, so that the myope can write without wearing glasses, and even the imaging can be adjusted to a slightly far distance from the myope to induce the myope to relax and alleviate the myopic condition and correct the vision.

4. The reflecting mirror group arranged in the desktop reading and writing auxiliary system can be replaced, so that different purposes can be achieved by different combinations, requirements of people with different eyesight can be met, and the independent reflecting mirror or reflecting mirror group can be replaced under the conditions of dirty, scratched, damaged mirror surface and the like, so that the system function can be recovered.

5. The utility model can also add other reflecting mirrors, lenses and other elements in the light path to further improve the imaging quality, size and imaging distance.
