Abstract
The utility model belongs to stationeries, and relates to a book corner protector. Books are the important study tools for human beings, but have a long-ignored problem that the book corners are easily curled up after long-time and frequent use, which influences the appearances of the books and results in damages to the books. The book corner protector is characterized in that a corner protector panel (3) includes a two-layer structure including a front side and a back side, and a sleeve (1) in the middle part; the corner protector panel (3) has a triangular shape; a ruler (5) is arranged on the right-angled edge of the panel (3); and an elliptic groove (6), a round groove (7), a square groove (8) and a rectangular groove (9) are formed on the panel (3). The grooves on the front side and the back side of the corner protector panel (3) correspond to each other; and the grooves penetrate through the front side and the back side. The book corner protector can effectively protect the book corners from being curled up, and has the advantages of multiple functions, convenient use for students, easy material selection, low cost, one-step die formation, and easy manufacture.
Description
Technical field
The utility model belongs to cultural goods, specifically a kind of not rolled-up books corner protector device in book angle of protecting.
Background technology
Books are the stepping stones to human progress, is the cultural goods that everyone needs, and the most important instrument of our student's study is given a lesson and all must use every day especially.A textbook need be browsed repeatedly every day, and is of long duration, causes the book angle to roll, neither attractive in appearance, causes breakage to books again.This is the problem that the most often runs into during we learn, and is again a long-standing problem, is a problem of being ignored by the people for a long time simultaneously.Need to use length ruler, set square in our study on the other hand, mathematics class often needs drawing tools to draw geometric figures such as circle, ellipse, square, rectangle.Invent a kind of book angle of can protecting and can not roll, the multi-purpose books corner protector device that has functions such as measuring length, picture again is necessary.
Summary of the invention
The purpose of this utility model provides a kind of book angle of can protecting and can not roll, and has the multi-purpose books corner protector device of functions such as measuring length, picture again.
The purpose of this utility model is achieved in that
A kind of books corner protector device is made up of corner protector device limit, corner protector device face version, device angle, and corner protector device face version is that front, the back side are two-layer, and the middle part is provided with chuck; Corner protector device face version be shaped as right angled triangle, right-angle side is provided with rule, the face version is provided with ellipse, circle, square, rectangle geometric figure groove.
The front of corner protector device face version, back side geometric figure groove in correspondence with each other, groove penetrates front and back.
The angle at three device angles is respectively 45 °, 90 ° and 45 °; It perhaps is 30 °, 90 ° and 60 °.
Main points of the present utility model are:
Books corner protector device face version has front, the back side two-layer, and the middle part is provided with chuck; Corner protector device face version be shaped as right angled triangle, during use the book angle is injected in the right angle; Protected the book angle can be not rolled-up.These books corner protector device can use plastic sheet, hard paper material to make.
To the utlity model has multiple functions such as measuring length, picture in order making, be provided with rule on the right-angle side of books corner protector device, the face version is provided with ellipse, circle, square, rectangle geometric figure groove.The front of corner protector device face version, back side geometric figure groove in correspondence with each other, groove penetrates front and back.Like this books corner protector device is taken off from the book angle, can measure length, utilize the geometric figure groove to draw according to the length chi on the corner protector device.Figure on the utility model face version can be oval, circle, square, rectangle, also can other essential figure be set according to work, study needs.
The utility model is easy to use, inserts the book angle, can protect the book angle not rolled-up; Taking off can be as drawing tools.
The utility model has the advantages that:
1, effectively protect the book angle not rolled-up.
2, function is many, makes things convenient for the student to learn.
3, material is easy to get, and cost is cheap.
4, use the mould one-shot forming, make easily.
