Description

Technical Field

[0001] The utility model relates to the technical field of stationery, more specifically to a loose-leaf notebook. Background Art

[0002] Loose-leaf notebooks are one of the most commonly used stationery items in daily work and study, and are composed of a cover, a binder (or coil), and paper. The biggest difference from ordinary notepads is that loose-leaf notebooks are more flexible to use, and the paper can be disassembled, replaced, and combined at will, and it is convenient to organize. At present, the loose-leaf notebooks in the prior art are large in size, with a hard spine, and the binder is installed between the front cover and the back cover, making the overall thickness higher. When stacking or storing loose-leaf notebooks, they are affected by the spine, making it difficult to place and store them flat, and it is easy to cause oblique sliding or squeezing of the loose-leaf book's plates to form depressions. At the same time, the folding of the spine plates of the loose-leaf book will produce sharp angles, which are more likely to scratch the user. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a loose-leaf book with a small volume and a soft back, which can reduce the overall thickness. After the soft back is turned over, the loose-leaf book is flatter as a whole and will not scratch the user.

[0004] The technical solution of the utility model is to provide a loose-leaf book with the following structure, including a front cover, a back cover and a spine, wherein the spine is connected between the side of the front cover and the side of the back cover; a loose-leaf clip is fixedly connected to the side of the back cover close to the spine, a loose-leaf core is arranged between the front cover and the back cover, and one side of the loose-leaf core is connected to the ring of the loose-leaf clip; the spine is made of flexible material; a through hole is opened at a position corresponding to the ring of the cover; when the front cover and the back cover are closed, the ring part passes through the through hole and is exposed outside the front cover.

[0005] After adopting the above structure, the loose-leaf book of the utility model has the following advantages compared with the prior art:

[0006] Since the spine of the loose-leaf book of the utility model is made of a flexible material, after the front cover and the back cover are closed, no sharp angle is formed between the spine and the front cover or the back cover, and the user will not be scratched during use. A through hole is provided at a position corresponding to the ring on the cover, and the ring part passes through the through hole and is exposed outside the cover. This structure is combined with the spine made of a flexible material, and after the front cover and the back cover are closed, the loose-leaf book is relatively flat, and the overall thickness and volume of the loose-leaf book can be reduced.

[0007] As an improvement, the side of the front cover is provided with a first connector, the side of the back cover is provided with a second connector, and the two sides of the spine are respectively connected to the first connector and the second connector. With this structure, the spine installation structure is simple and easy to assemble.

[0008] As an improvement, the first connector is integrally formed with the front cover, and the second connector is integrally formed with the back cover. With this structure, the loose-leaf book has greater strength and is more convenient to manufacture.

[0009] As an improvement, the two sides of the back spine are respectively connected to the outer sides of the first connector and the second connector. After adopting this structure, the back spine is wrapped around the outer sides of the first connector and the second connector, which is more convenient to manufacture.

[0010] As an improvement, the two sides of the spine are respectively fixed to the first connector and the second connector by heat pressing. With this structure, the spine is more convenient to fix.

[0011] As an improvement, the rings are provided at both ends of the binder, and the through holes are provided at both ends of the cover near the side of the binder. With this structure, the binder can be simplified and its cost can be reduced without affecting its use.

[0012] As an improvement, a notch is provided at a position on the side edge of the cover corresponding to the handle of the binder, and one side of the handle is embedded in the notch. After adopting this structure, the notch is used to avoid the handle. BRIEF DESCRIPTION OF THE DRAWINGS
