Abstract

The utility model relates to a tool which is convenient for teenagers to read and write and can prevent short sighted. The utility model is mainly composed of two splints which are similar to teaching materials or file folders but can roll over to the left or to the right. When people read or write the pages of a book is clamped by the clamps arranged on the top ends of the splints, a 'T'-shapedd frame composed of a cross bar and an upright post is stood on the lower end of the left splint, and the cross bar just bars the part from the chin to the corners of mouth of the users to restrict the users to lean any longer to the front. Thereby, the distance of the eyes and the book is kept within the bound of distance of distinct vision of the eyes, and the purpose of short sighted preventing is achieved. When the utility model is unused, the cross bar is retracted, a supporting frame is laid down and leaned tightly to the left sprint, and at last the two splints are rejoined to be collected.

Description

Reading and writing clip preventing against nearsightedness

The instrument that the utility model relates to the pre-myopia prevention of a kind of teenager of being specially adapted to, easy-to-read and writes.

At present, greatly, in, among the pupil, the ratio of myopia number is very high, and it is in rising trend, therefore, adolescent student, the head of a family, country and society all very are concerned about the problem of control juvenile shortsightedness, and development, apparatus and medicines such as myopia prevention desk lamp have been produced, but do not deal with problems at all, do not see as yet the teenager is being read, make eye in the writing process, remain the device of the distance of distinct vision of normal eye between the book, also do not see when reading thick book and can make the motionless device of page holder, thereby the prevention teenager reads, eye when writing, the book distance too closely causes the problem of myopia also unresolved.

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, can make the teenager read, remain when writing the unlikely correct distance that causes myopia and provide a kind of, can also make the motionless device of page holder when reading thick book, it can fundamentally prevent large, medium and small student that myopia takes place.

The purpose of this utility model reaches by following approach: the utility model mainly is made up of the clamping plate that two hardboards or other materials are made, the right-hand member of left side clamping plate and the left end of right clamping plate all have the seamed edge of folding about 20 mm wides, this two seamed edge can twist together with spring steel wire as lecture portfolio, also can as file, between this two seamed edge, connect wide the 3rd about 20 a millimeters seamed edge again, one seamed edge inboard refills a clip, (lecture portfolio and file can only turn over left, and clamping plate of the present utility model then can turn over to the left or to the right).The periphery of left and right clamping plate is reinforced with wide about 20 millimeters foil, respectively adorns a Small clamp on the mid point left side on left and right clamping plate top, in order to clamp page, in case page disorderly turns over because of elasticity.Fix a short pipe on the right of left clamping plate bottom.A slit is opened in the center at its right-hand member top, and its left end has about 90 a ° breach that communicates with slit.Adorn a Cylinder in the pipe of garden as rotating shaft, connect with the column of making of band iron or flat tube, the width of the slit at garden pipe right-hand member top center place should make column can just push in the groove in vertical state, and the top of column connects with the cross bar that the pipe that is nested together by two different-diameters is formed.When reading and writing, tubule in the cross bar sleeve pipe is pulled out to the right, and column is pushed to the right in the slit of garden pipe right-hand member in vertical state, at this moment, the height of column makes the cross bar hurdle locate at user's chin to mouth (crust) just, restriction user's eyes can not be more forward near books or writing paper, thereby eye, book distance are often remained in the distance of distinct vision (250-300 millimeter) scope of normal eye.When not using the utility model, the tubule of cross bar is pushed in the bassoon left, and column is pushed left in the breach of garden pipe, 90 ° of angles of column clamping plate commentaries on classics are left abutted against on the left clamping plate, at last left and right sides clamping plate are closed up collection.As when adopting the lecture portfolio style, before closing up, must folder one suitable thick object in two seamed edges.Second splint can be parallel, and when adopting the file style, because of the support of the 3rd seamed edge is arranged between two seamed edges, second splint directly closes up and gets final product.

The utility model compared with prior art has the following advantages:

1, make the teenager when reading and writing, eye, book distance can remain in the distance of distinct vision scope of normal eye all the time, the fundamentally generation of pre-myopia prevention;

2, left and right clamping plate can turn over left also and can turn over to the right, can satisfy when reading thick book, and first half turns over left, custom that latter half turns over to the right or requirement, thereby easy to use;

When 3, reading thick book, the Small clamp on available second splint top is clamped page, prevents that page from stirring voluntarily because of elasticity, thereby needn't pin book with hand at any time and read.

Description of drawings: accompanying drawing is the schematic perspective view of lecture portfolio style " myopia prevention read, Filling appliance for writing ", (" myopia prevention is read, Filling appliance for writing " only many one article of the 3rd seamed edges of file style, in adorn a clip).

The utility model describes in detail below with reference to the embodiment in the accompanying drawing: as shown in drawings.Shell of the present utility model mainly is made up of left clamping plate 1 and right clamping plate 2.Material can be hardboard, plastic plate or laminate etc.The right-hand member of left side clamping plate 1 and the left end of right clamping plate 2 all have folding wide about 20 a millimeters seamed edge, this two seamed edge twists together with spring steel wire as lecture portfolio, also can as file, between this two seamed edge, connect wide the 3rd about 20 a millimeters seamed edge again, the inboard refills a clip, lecture portfolio and file can only turn over left, and file then can turn over to the left or to the right.The periphery of left and

right clamping plate
