Abstract
Description
Technical Field
[0001] This utility model belongs to the field of exercise book technology, specifically relating to an exercise book that is easy to copy. Background Technology
[0002] Exercise books are paper notebooks used for writing exercises and recording knowledge. They are essential for students and self-learners in their daily studies. Their basic structure consists of a cover, back cover, and inner pages bound together. The cover often has pictures or subject categories printed on it, serving to protect the inner pages and for classification. Based on the inner page format, exercise books come in various types, such as lined notebooks, grid notebooks, and traditional Chinese character-grid notebooks. Lined notebooks are suitable for daily note-taking and essay writing exercises; grid notebooks are convenient for drawing charts and writing neat mathematical formulas; traditional Chinese character-grid notebooks are specifically designed for practicing Chinese character writing, helping learners to standardize stroke structure. Based on binding methods, there are perfect binding, saddle stitching, and loose-leaf binding. Perfect binding is sturdy and durable, saddle stitching is easy to flip through, and loose-leaf binding allows for flexible adjustment of the number of pages and content. In practical use, students use them to record class notes and complete homework, while working professionals also use exercise books for meeting minutes and work planning. Their wide applicability makes them a powerful tool to assist in learning and work.
[0003] Currently, to improve copying efficiency, existing exercise books typically use a carbon paper sandwiched between two sheets of paper. The pressure applied when writing on the first sheet is then used to copy the text onto the second sheet. However, traditional exercise books do not have copying capabilities and require users to place the carbon paper themselves. However, the carbon paper may not be properly positioned, causing the writing area of the first sheet to be outside the copying area of the carbon paper, resulting in some text not being properly copied onto the second sheet. Utility Model Content
[0004] The purpose of this invention is to provide a convenient practice book for copying, aiming to solve the problem that existing practice books, in order to improve copying efficiency, usually hold a carbon paper between two sheets of paper and then copy the writing onto the next sheet by applying pressure when writing on the previous sheet. However, traditional practice books do not have copying capabilities and require the user to place the carbon paper themselves. However, the carbon paper may not be properly positioned, resulting in the writing area of the previous sheet not being within the copying area of the carbon paper, thus causing some writing to not be well copied onto the next sheet.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a practice book for easy copying, comprising a practice book cover, practice book paper adhered to the inner side of the practice book cover, a connecting strip connected to one end of the practice book cover, a first carbon paper limiting frame connected to one side of the connecting strip, a second carbon paper limiting frame connected to one side of the connecting strip, and carbon paper held between the first carbon paper limiting frame and the second carbon paper limiting frame.
[0006] As a preferred embodiment of this utility model of a convenient copy exercise book, the connecting strip is made of spandex.
[0007] As a preferred embodiment of this utility model of a convenient copying exercise book, the first and second copying paper limiting frames are hollow structures.
[0008] As a preferred embodiment of this utility model of a convenient copying exercise book, the surface of the first copy paper limiting frame is provided with a first mounting groove, and a first magnetic block is installed on the inner side of the first mounting groove.
[0009] As a preferred embodiment of this utility model of a convenient copying exercise book, the surface of the second copy paper limiting frame is provided with a second mounting groove, and a second magnetic block is installed on the inner side of the second mounting groove.
[0010] As a preferred embodiment of this utility model for a convenient copy exercise book, the first magnetic block is adapted to the size of the first mounting slot, and the second magnetic block is adapted to the size of the second mounting slot.
[0011] As a preferred embodiment of this utility model of a convenient copying exercise book, the first copy paper limiting frame can form a magnetic attraction structure with the second copy paper limiting frame through the first magnetic block and the second magnetic block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By holding the carbon paper between the first and second carbon paper limiting frames, and then flipping the carbon paper over and inserting it between two practice sheets, the first and second carbon paper limiting frames can effectively limit the carbon paper, thus preventing the writing area of the previous practice sheet from being outside the copying area of the carbon paper.
[0014] With the setting of the first and second magnetic blocks, when the carbon paper is sandwiched between the first carbon paper limiting frame and the first carbon paper limiting frame, the first and second magnetic blocks will be magnetically attracted to each other, thereby fixing the carbon paper. The magnetically attracted first and second carbon paper limiting frames also make it very convenient to replace the carbon paper. You only need to pry the first and second carbon paper limiting frames apart to take out and replace the carbon paper. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 The present invention provides the following technical solution: a practice book for easy copying, including a practice book cover 1, practice book paper 2 glued to the inner side of the practice book cover 1, a connecting strip 3 connected to one end of the practice book cover 1, a first carbon paper limiting frame 4 connected to one side of the connecting strip 3, a second carbon paper limiting frame 5 connected to one side of the connecting strip 3, and a carbon paper 6 held between the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5.
[0023] Preferably, the connecting strip 3 is made of spandex, and the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5 are hollow structures;
[0024] It should be noted that the spandex connecting strip 3 has high elasticity and can stretch as the cover is opened and closed. At the same time, the fabric is soft and will not scratch your hands, and it can also add a soft texture to the exercise sheet. Furthermore, the highly elastic spandex connecting strip 3 allows the first carbon paper limiting frame 4, the second carbon paper limiting frame 5, and the carbon paper 6 to be flipped and inserted between the two exercise sheet papers 2 at different positions.
[0025] In practical use, after placing the carbon paper 6 flat between the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5, the assembled first carbon paper limiting frame 4, second carbon paper limiting frame 5, and carbon paper 6 are flipped over and carefully inserted between the two practice sheets 2. The first carbon paper limiting frame 4 and the second carbon paper limiting frame 5 are made of high-strength hard plastic, and the frame size is precisely matched with the writing area of the practice sheet 2. In this way, whether writing quickly or with force, the carbon paper 6 can be firmly in the predetermined position, effectively avoiding the situation where the writing area of the previous practice sheet 2 deviates from the copying area of the carbon paper 6, ensuring that every copy is accurate and clear, and greatly improving writing efficiency and copying quality.
[0026] Preferably, the surface of the first carbon paper limiting frame 4 is provided with a first mounting groove 7, and a first magnetic block 8 is installed inside the first mounting groove 7. The surface of the second carbon paper limiting frame 5 is provided with a second mounting groove 9, and a second magnetic block 10 is installed inside the second mounting groove 9. The size of the first magnetic block 8 is adapted to the size of the first mounting groove 7, and the size of the second magnetic block 10 is adapted to the size of the second mounting groove 9. The first carbon paper limiting frame 4 can form a magnetic attraction structure with the second carbon paper limiting frame 5 through the first magnetic block 8 and the second magnetic block 10.
[0027] In practical use, by setting the first magnetic block 8 and the second magnetic block 10, when the carbon paper 6 is sandwiched between the first carbon paper limiting frame 4 and the first carbon paper limiting frame 5, the first magnetic block 8 and the second magnetic block 10 will be magnetically attracted to each other, thereby fixing the carbon paper 6. Furthermore, the magnetically attracted first carbon paper limiting frame 4 and second carbon paper limiting frame 5 make it very convenient to replace the carbon paper 6. You only need to pry open the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5 to take out and replace the carbon paper 6.
[0028] Working principle: First, the carbon paper 6 is placed flat between the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5. Then, the assembled first carbon paper limiting frame 4, second carbon paper limiting frame 5, and carbon paper 6 are flipped over and carefully inserted between two practice sheets 2. The first carbon paper limiting frame 4 and second carbon paper limiting frame 5 are made of high-strength hard plastic, and the frame size is precisely matched with the writing area of the practice sheet 2. In this way, whether writing quickly or with force, the carbon paper 6 can be stably held in the predetermined position, effectively avoiding the writing area of the previous practice sheet 2. The system ensures accurate and clear copying every time the copying area deviates from the copying area of the carbon paper 6, greatly improving writing efficiency and copying quality. Furthermore, through the setting of the first magnetic block 8 and the second magnetic block 10, when the carbon paper 6 is sandwiched between the first carbon paper limiting frame 4 and the first carbon paper limiting frame 5, the first magnetic block 8 and the second magnetic block 10 will be magnetically attracted to each other, thereby fixing the carbon paper 6. The magnetically attracted first carbon paper limiting frame 4 and the second carbon paper limiting frame 5 also make it very convenient to replace the carbon paper 6. You only need to pry open the first carbon paper limiting frame 4 and the second carbon paper limiting frame 5 to remove and replace the carbon paper 6.
[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
