Description
Technical field
The utility model relates to a kind of study article, specifically a kind of anti-knuckle cover.
Background technology
People are when reading; Because the page surface is directly exposed in the dry air, and the number of times of contact hand is more, and frequent browsing can make the moisture content in the page change; Thin paper approaches again also has certain thickness; If the single face of paper (or two-sided) makes moist and causes that positive and negative tension force is inconsistent, the back aqueous vapor of making moist of the paper below the page is not easy to discharge, and the top papery back moisture content that makes moist evaporates easily; So the fiber of paper surface can be strained; And the deflection of printing paper feed machine direction generally is better than laterally, so change under both actings in conjunction in the variation in tension of thin paper positive and negative and the humidity of paper surface, paper will inevitably take place to curl or the book angle upwarps; Especially for the pupil, often have more than is needed several days of the textbook of New Development, just curl in the book angle, alice, knuckle or fracture, and influence is read and is looked.
The utility model content
The purpose of the utility model is to provide a kind of anti-knuckle cover, and this cover has to curl in the book angle that prevents books and reference materials, the characteristics of alice, knuckle or fracture.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of anti-knuckle cover; Its structure comprises book clamp and magnet; Described book clamp is the hard sheet shape that has cavity; And all the other face closures of a side opening, the corresponding up and down two sides of described cavity is respectively arranged with a magnet, and described magnet attracts each other.
The curved limit of the open side edges of described book clamp.
The beneficial effect of the utility model is: during use, the strip of paper used for sealing of books is inserted in the cavity of book clamp, because the suction-operated of the magnet in the cavity, book clamp can not scheme to come off voluntarily on the book envelope certainly; For the integrality that keeps the books outward appearance and attractive in appearance, also book clamp can be installed respectively on front cover and back cover; When book runs through the back or do not browse for a long time, can slightly firmly take off cover, so that be placed on other book; The utility model is simple in structure, and is easy for installation, reusable and can effectively protect books.
