Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of notebook applications, in particular to a hinge notebook binding coil. Background Art
[0002] A hinge notebook is a binding method that combines a cover and inner pages, and is usually used for daily notes, handwritten records, or writing and recording for professional purposes. The characteristics of this notebook lie in its flexibility and portability, and at the same time, it also provides a relatively firm binding method. Hinge notebooks are widely used in learning, work, meeting records, creative thinking, note sorting, etc. Due to its flexibility and structural firmness, it is suitable for long-term use and carrying. With its strong binding method and diverse design options, hinge notebooks have become widely used note-taking and recording tools, meeting the needs and aesthetics of different people.
[0003] Existing hinge notebooks usually use the method of fixing with leads or coil binding. The method of fixing with leads cannot change the number of papers. Traditional binding coils have high production costs, cannot be reused, and are difficult to disassemble. Summary of the Utility Model
[0004] To solve the defects existing in the prior art, the utility model provides a hinge notebook binding coil.
[0005] The technical solution adopted by the utility model is: a hinge notebook binding coil, including a connecting main rod, an upper hinge rod, and a lower hinge rod; the upper hinge rod and the lower hinge rod are symmetrically distributed on both sides of the connecting main rod. A male buckle is arranged at the outer end of the upper hinge rod, and a female buckle is arranged at the outer end of the lower hinge rod. The upper hinge rod and the lower hinge rod can be buckled through the male buckle and the female buckle to form an annular structure.
[0006] A further improvement to the above solution is that the middle of the connecting main rod is thinner than both ends to form a foldable structure, so that the connecting main rod 1 and the upper and lower hinge rods on both sides can be folded inward.
[0007] A further improvement to the above solution is that the inner parts of the upper hinge rod and the lower hinge rod are groove-shaped, which can ensure structural stability while saving materials and reducing costs.
[0008] A further improvement to the above solution is that the female buckle is a groove-shaped structure with a narrow outer part and a wide inner part, and the male buckle is a protruding structure with a narrow front and rear ends and a wide middle part, so that the male buckle can be inserted into the female buckle to form a stable fit.
[0009] A further improvement to the above solution is that the connecting main rod, the upper hinge rod, and the lower hinge rod are made of PP material. The PP material can undergo slight deformation, enabling the upper hinge rod and the lower hinge rod to fold around the connecting main rod, and causing slight expansion at the entrance of the female buckle when the male buckle can be inserted into the female buckle to form a fit.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] Firstly, the present utility model uses PP material, which can be injection-molded through a mold, with low production costs. Secondly, it can manually disassemble and buckle the binding coil to modify the number of sheets of paper, and can be reused. Thirdly, it adopts an assembly method where the male buckle and the female buckle are buckled with each other, the material can undergo slight deformation, and the binding and disassembly are simple. Description of the Drawings
[0012] The drawings are used to provide a further understanding of the present utility model and constitute a part of the specification. They are used together with the embodiments of the present utility model to explain the present utility model, and do not constitute a limitation to the present utility model. In the drawings:

[0017] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.
[0018] A hinge notebook binding coil includes a connecting main rod 1, an upper hinge rod 2, and a lower hinge rod 3; the upper hinge rod 2 and the lower hinge rod 3 are symmetrically distributed on both sides of the connecting main rod 1, a male buckle 4 is provided at the outer end of the upper hinge rod 2, a female buckle 5 is provided at the outer end of the lower hinge rod 3, and the upper hinge rod 2 and the lower hinge rod 3 can be buckled through the male buckle 4 and the female buckle 5 to form an annular structure.
[0019] Among them, the middle of the connecting main rod 1 is thinner than both ends to form a foldable structure, enabling the connecting main rod 1, the upper hinge rod 2, and the lower hinge rod 3 to fold inward.
[0020] Among them, the upper hinge rod 2 and the lower hinge rod 3 are internally grooved, which can ensure structural stability while saving materials and reducing costs.
[0021] Among them, the female buckle 5 is a grooved structure with a narrow outer and wide inner shape, and the male buckle 4 is a protruding structure with a narrow front and rear and a wide middle, so that the male buckle 4 can be inserted into the female buckle 5 to form a stable fit.
[0022] Among them, the connecting main rod 1, the upper hinge rod 2 and the lower hinge rod 3 are made of PP material. The PP material can undergo slight deformation, so that the upper hinge rod 2 and the lower hinge rod 3 can be folded around the connecting main rod 1, and when the male buckle 4 can be inserted into the female buckle 5, the entrance of the female buckle 5 expands slightly to form a fit.
[0023] Working principle: During the binding process, first pass the holes on the paper through the upper hinge rod 2 or the lower hinge rod 3, and at the same time hold the upper hinge rod 2 and the lower hinge rod 3 on both sides of the connecting main rod 1 and buckle them inward, so that the male buckle 4 on the upper hinge rod 2 is inserted into the female buckle 5 on the lower hinge rod 3 to form a fit. At this time, the upper hinge rod 2, the lower hinge rod 3 and the connecting main rod 1 form an annular structure to complete the binding.
[0024] After the binding is completed, if you want to add or reduce paper, hold the upper hinge rod 2 and the lower hinge rod 3 respectively and move them to both sides of the connecting main rod 1 to separate the male buckle 4 and the female buckle 5, then the disassembly can be completed. At this time, paper can be placed or reduced, and then the binding steps can be carried out to achieve reuse.
[0025] In the description of the present invention, it should be noted that unless otherwise specified, the meaning of "a plurality" is two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0026] Although the content of the present invention has been introduced in detail through the above preferred embodiments, it should be recognized that the above description should not be regarded as a limitation of the present invention. After those skilled in the art have read the above content, various modifications and substitutions to the present invention will be obvious. Therefore, the protection scope of the present invention should be defined by the appended claims.
