Description

Technical Field

[0001] This utility model relates to the field of exercise book technology, specifically a portable foldable exercise book designed to prevent myopia. Background Technology

[0002] Workbooks are essential tools for students to record knowledge and complete assignments, and their daily use is extremely widespread. Traditional workbooks often use perfect binding or saddle stitching to hold the pages together, with a single-layer cardstock cover. While simple in structure, they offer limited functionality and cannot effectively address the visual fatigue caused by prolonged writing. Furthermore, these workbooks are prone to wear and tear and corner folds during use and transport, lack protective mechanisms, and are inconvenient for replacing pages, resulting in a short lifespan.

[0003] While some existing technologies feature replaceable inner pages, their complex structures and lack of stable fixing methods make the inner pages prone to loosening or falling off during writing or carrying, affecting the user experience. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a portable foldable anti-myopia exercise book, including a cardboard, an arc-shaped connecting plate fixedly connected to the left end of the cardboard, a slide rail fixedly connected to the front of the arc-shaped connecting plate, a slide bar slidably connected inside the slide rail, an exercise book body fixedly connected to the top of the slide bar, a threaded hole one at the front end of the slide bar, a threaded hole two at the front end of the slide rail, a screw threaded inside the threaded hole two, and a protective layer provided on the surface of the exercise book body.

[0005] The above technical solution, through the integrated structure of cardboard, curved connecting plate, slide rail, slider, screw, and yellow protective layer, allows the notebook body to be positioned and locked in one go after sliding into the rail, forming a flat and light-filtering rigid writing surface; loosening the screw in the opposite direction allows the old core to be pulled upwards and the new core to be slid in. The entire replacement process requires no tools and does not damage the paper, achieving rapid core replacement, reuse, and reduced material consumption.

[0006] As a further improvement to the above solution, two pieces of cardboard are provided, and the two pieces of cardboard are evenly distributed on the left and right ends with the center of the front of the arc-shaped connecting plate symmetrically.

[0007] With the above technical solution, two pieces of cardboard are symmetrically arranged with the arc-shaped connecting plate as the center. After folding, they form a box-shaped protective shell that is balanced from left to right, avoiding the warping and deformation caused by traditional single-sided folding.

[0008] As a further improvement to the above solution, the first threaded hole and the second threaded hole are concentric, and the front end of the screw is threadedly connected inside the first threaded hole.

[0009] Through the above technical solution, the concentric design of threaded hole one and threaded hole two allows the screw to pass through the inner wall of the slide rail and be threaded into the inside of the slide bar when locked.

[0010] As a further improvement to the above solution, the material of the protective layer is a yellow dye protective layer.

[0011] Through the above technical solution, the yellow dye protective layer forms a cutoff absorption near 560nm in the visible light band, reducing the peak value of high-energy blue light in LED ambient light, while maintaining high color temperature compatibility, making the contrast between text and grid lines moderate, and reducing the frequent adjustment of the ciliary muscle.

[0012] As a further improvement to the above solution, the surface of the cardboard is fitted with an anti-slip sleeve, a connecting strip is fixedly connected to the rear end of the cardboard, a female buckle is fixedly connected to the rear end of the connecting strip, and a male buckle is fixedly connected to the rear end of the cardboard.

[0013] Through the above technical solution, the anti-slip sleeve increases grip friction, and after the female buckle and the female buckle are fastened together, the cardboard forms a closed box, completely wrapping the inner pages of the exercise book and protecting the exercise book itself.

[0014] As a further improvement to the above solution, the anti-slip sleeve is made of microfiber PU leather.

[0015] Through the above technical solutions, microfiber PU leather has a microporous breathable structure, a delicate feel, and is resistant to bending. It does not cause sweating even after long-term use, and is also resistant to ink and oil stains. It can be wiped clean with water to keep the shell clean.

[0016] As a further improvement to the above solution, the connecting strip is located at the rear end of the cardboard on the left end of the arc-shaped connecting plate, and the sub-buckle is located at the rear end of the cardboard on the right end of the arc-shaped connecting plate.

[0017] With the above technical solution, the connecting strip and the female buckle are located on the left cardboard, and the female buckle is located on the right cardboard. After folding, the buckling direction is perpendicular to the writing and unfolding direction, forming a self-locking closure.

[0018] As a further improvement to the above solution, the female buckle is adapted to the female buckle.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes a quick-release structure consisting of a slide rail, a slider, and a screw, allowing the notebook body to slide into and lock into the cardboard frame in one go. By unscrewing the screw in the opposite direction, it can be pulled upwards for replacement. This enables the notebook pages to be quickly disassembled and reused, extending the lifespan of the outer casing, reducing usage costs, and minimizing resource waste.

[0021] This invention, by setting a yellow dye protective layer and a foldable cardboard, combined with a female-female buckle closure mechanism, allows the exercise book to unfold into a writing surface with yellow light filtering when in use, and fold into a rigid portable case when not in use, thus achieving the effects of reducing blue light stimulation, relieving visual fatigue, and being convenient to carry around.
