Description

Technical Field

[0001] The utility model belongs to the technical field of loose-leaf binding and provides a loose-leaf binding device and a loose-leaf notebook. Background Art

[0002] Existing loose-leaf notebooks are bound with stainless steel rings, or electroplated iron wires or plastic-coated iron wires. Not only are they not environmentally friendly in terms of recycling, but they are also not reusable. Most importantly, they hurt your hands when you write on the back side. You can't make full use of the back side for writing. There are many types of existing products, but none of them solve the problem of hurting your hands, which makes it impossible to write on the back side, or students are unwilling to write, which results in a huge waste of notebooks.

[0003] The applicant has applied for a patent: a binding structure of a loose-leaf notebook, application number CN202220274571.4, which involves a base plate, a binding fork, a bayonet and a card block, but the card block is set as a single one. In the early and middle stages of the use of the binding structure, due to the clamping relationship between the binding fork and the bayonet and the friction of the material itself, the binding fork and the base plate of the card block have a certain tight fit relationship after being inserted into the bayonet, that is, the binding fork is not easy to shake or loosen, but when the binding structure is repeatedly used, that is, after the binding fork is plugged in many times, the tight fit relationship between the binding fork and the base plate changes, the bayonet becomes larger, which causes shaking or loosening between it and the binding fork, and then the ring shape of the bent binding fork is sometimes large and sometimes small, thereby affecting the later writing and use effect. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and to provide an environmentally friendly, comfortable and reusable loose-leaf binding device and a loose-leaf notebook, so that the binding part of the loose-leaf notebook can be reused and the problem that the flexible binding fork is prone to shaking or loosening relative to the base plate is solved.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] The utility model relates to a loose-leaf binding device, comprising: a base plate serving as a support, having a first surface and a second surface opposite to the first surface; a plurality of bayonet ports arranged along the length direction of the base plate and penetrating the first surface and the second surface of the base plate; a plurality of flexible binding forks arranged along the length direction of the base plate and corresponding to the plurality of bayonet ports one by one, and each flexible binding fork having a bottom end and a top end arranged oppositely, the bottom end being fixedly arranged on the first surface of the base plate, and the top end being a free end; wherein, after each flexible binding fork is bent and passes through the loose-leaf notebook, the top end is inserted into the corresponding bayonet port from the second surface along the direction toward the first surface to form a snap fit with the base plate, and the top end and the bottom end of each flexible binding fork after forming a snap fit with the base plate are spaced apart in the width direction of the base plate; the top end of each flexible binding fork is provided with two card blocks corresponding to each other and spaced apart from each other, and the two card blocks are respectively located on both sides of the thickness direction of the base plate after the top end forms a snap fit with the base plate. In this way, by designing the card block, it is not only ensured that the flexible binding fork is firmly fixed in the bayonet of the base plate and is not easy to withdraw and fall off; it is also ensured that the top of the flexible binding fork and the base plate are firmly and tightly connected, and the position of the card block is relatively fixed, not easy to be displaced or loosened, and can provide a better binding effect. In this way, the flexible binding fork can be firmly fixed on the base plate, and will not fall off or deform due to the action of external force, which helps to improve the service life and stability of the product. In addition, compared with the single card block set at the top of the flexible binding fork, the upper and lower corresponding and spaced arrangement of the two card blocks can provide better support and stability, achieve better embedding and connection between the flexible binding fork and the base plate, provide a stronger bonding force, and effectively prevent the flexible binding fork from shaking or loosening during use.

[0007] Optionally, after the top end of each flexible binding fork forms a snap fit with the base plate, the outer snap block is convexly disposed or embedded in the first surface of the base plate, and the inner snap block is convexly disposed or embedded in the second surface of the base plate. The snap block is convexly disposed on the base plate surface, so that the flexible binding fork can be easily inserted or removed from the base plate; and the snap block is embedded in the base plate surface, so that the surface that fits the loose-leaf paper of the loose-leaf notebook can be kept flat, which is convenient for writing.

[0008] Optionally, the base plate, the flexible binding fork and the card block are integrally formed. This design can improve the overall strength and stability of the product, reduce the seams and connections between the components, and thus improve the service life and reliability of the product. At the same time, the integral molding manufacturing can also simplify the production process, improve production efficiency and reduce production costs.

[0009] Optionally, the base plate, flexible binding fork and card block are made of silicone rubber material, which is soft, durable and reusable, helping to solve the environmental problems, discomfort and inconvenience of existing loose-leaf notebooks. Users do not need to worry about hurting their hands, and can write notes, exercises, etc. on the back at will, thereby improving the efficiency of notebook use.

[0010] Optionally, the second surface of the substrate is provided with a slope that is thinned and extends outward in the thickness direction of the substrate. This design can minimize the increase in the height of the notebook when it is placed on the substrate by providing a thinning slope facing the notebook on the away side of the substrate, so that the notebook tends to be in a horizontal state, which effectively improves the writing experience and makes the user more stable and comfortable when writing. At the same time, reducing the padding of the notebook by the substrate can reduce the jitter and shaking during writing, and improve the precision and accuracy of writing.

[0011] Optionally, the first surface of the base plate is provided with an inwardly inclined conical groove toward the bayonet. This design allows the bayonet to provide a certain extraction angle, making it easier to extract or withdraw the flexible binding fork from the base plate bayonet, reducing the resistance and friction during extraction. In this way, the user will be more convenient and smooth when performing the binding operation.

[0012] Optionally, the second surface of the base plate is provided with an inwardly sunken groove toward the slot. This design allows the inner block of the double block structure to be sunken in the groove, so that after the flexible binding fork is bent and inserted into the base plate, no convex platform will appear on the second surface due to the inner block, ensuring that the second surface is flat and easy to fit with loose-leaf paper for convenient writing.

[0013] The utility model also discloses a loose-leaf notebook, comprising loose-leaf papers and a binding structure. The binding structure is used to bind a plurality of loose-leaf papers together, and the binding structure adopts the loose-leaf binding device mentioned above.

[0014] Compared with the prior art, the utility model has one or more of the following advantages:

[0015] 1. The loose-leaf binding device has good elasticity and pressure resistance provided by silicone rubber binding to ensure the stability and durability of the loose-leaf binding device. It can withstand multiple page turning and opening, and is not easy to be damaged or deformed, thereby extending the service life of the loose-leaf notebook. The silicone rubber binding is smooth and soft, will not hurt the hand, and can provide a more comfortable writing experience. It can also be written on the back of the loose-leaf notebook, making full use of both sides of the loose-leaf notebook, so that users will not feel discomfort or pain when writing, and can write more smoothly.

[0016] 2. The loose-leaf binding device provides better flexibility and durability through silicone rubber binding, so that the loose-leaf notebook can be rolled up and put into a backpack or pocket for easy carrying, and can ensure a long service life of the loose-leaf notebook; and the silicone rubber binding is degradable and environmentally friendly, which can reduce the consumption of resources and reduce the impact on the environment, which is in line with the concept of sustainable development.

[0017] 3. If you need to remove or change the order of notes, you can open the bayonet and easily change pages and rebind. You can also reuse it after writing notes and replace the inner core of the loose-leaf notebook.

[0029] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0030] like Figure 1-5 As shown, the loose-leaf binding device comprises: a base plate 3 having a first surface 31 and a second surface 32 opposite to the first surface 31; a plurality of bayonet holes 1 arranged along the length direction of the base plate 3 and penetrating the first surface 31 and the second surface 32 of the base plate 3; a plurality of flexible binding forks 2 arranged along the length direction of the base plate 3 and corresponding to the plurality of bayonet holes 1 one by one, and each flexible binding fork 2 has a bottom end 21 and a top end 22 arranged opposite to each other, the bottom end 21 is fixedly arranged on the first surface 31 of the base plate 3, and the top end 22 is a free end; wherein, after each flexible binding fork 2 is bent and passes through the loose-leaf notebook, the top end 22 is clamped into the corresponding one from the second surface 32 in the direction toward the first surface 31. The top end 22 and the bottom end 21 of each flexible binding fork 2 are arranged at intervals in the width direction of the base plate 3 in the corresponding bayonet 1 to form a bayonet fit with the base plate (3). After forming a bayonet fit with the base plate 3, the top end 22 and the bottom end 21 of each flexible binding fork 2 are arranged at intervals in the width direction of the base plate 3; the top end 22 of each flexible binding fork 2 is provided with two bayonet blocks 4 which correspond to each other and are spaced apart from each other. After the top end 22 forms a bayonet fit with the base plate 3, the two bayonet blocks 4 are respectively located on both sides of the thickness direction of the base plate 3, that is, the distance between the two bayonet blocks 4 corresponding to each other is used to hold the base plate 3, which can ensure a stable and tight connection between the top end of the flexible binding fork and the base plate, and make the position of the bayonet block relatively fixed, not easy to be displaced or loosened, and can provide a better binding effect.

[0031] By adopting the above scheme, the card block at the top of the flexible binding fork is connected to the base plate to form a ring structure to bind the loose-leaf notebook, that is, the flexible binding fork 2 is bent away from the corresponding card slot 1, passes through the loose-leaf notebook, and is connected to the card slot 1 on the base plate 3, and the notebook is fixed by the tension of the silicone rubber material itself. The number of flexible binding forks 2 and the product length can be adjusted according to the size of the notebook. In addition, compared with the single card block set at the top of the flexible binding fork, the upper and lower corresponding and spaced arrangement of the two card blocks can provide better support and stability, achieve better embedding and connection between the flexible binding fork and the base plate, provide a stronger bonding force, and effectively prevent the flexible binding fork from displacement or shaking during use.

[0032] In this embodiment, after the top end 22 of each flexible binding fork 2 forms a snap fit with the base plate 3, the outer clamping block 4 is convexly disposed or embedded in the first surface 31 of the base plate 3, and the inner clamping block 4 is convexly disposed or embedded in the second surface 32 of the base plate 3. In this way, by convexly disposed on the surface of the base plate 3, the flexible binding fork 2 can be easily operated to be inserted or withdrawn at the clamping opening 1 of the base plate 3; and by embedding the clamping block 4 on the surface of the base plate 3, the surface of the base plate 3 that is in contact with the loose-leaf paper 8 of the loose-leaf notebook can be kept flat, which is convenient for writing.

[0033] In this embodiment, the base plate 3, the flexible binding fork 2 and the clamping block 4 are an integrally formed structure, which can improve the overall strength and stability of the product on the one hand, and simplify the production process on the other hand, improve production efficiency and reduce production costs.

[0034] In this embodiment, the base plate 3, the flexible binding fork 2 and the card block 4 are made of silicone rubber. In this way, the good elasticity and pressure resistance provided by the silicone rubber binding ensure the stability and durability of the loose-leaf binding device, which can withstand multiple page turning and opening, and is not easy to be damaged or deformed, thereby extending the service life of the notebook; and the silicone rubber binding is smooth and soft, will not hurt the hand, can provide a more comfortable writing experience, and can write on the back of the notebook, making full use of the double sides of the notebook, so that the user will not feel discomfort or pain when writing, and can write more smoothly.

[0035] In this embodiment, the second surface 32 of the substrate 3 is provided with a bevel 5 that is thinned and extends outward in the thickness direction of the substrate 3. The bevel can reduce the padding of the substrate on the notebook, thereby reducing the jitter and shaking during writing and improving the precision and accuracy of writing. The first surface 31 of the substrate 3 is provided with an inward-inclined conical groove 6 toward the bayonet 1. The conical groove makes it easier for the flexible binding fork to be pulled out or withdrawn from the bayonet of the substrate, reduces the resistance and friction during pulling out, and makes it more convenient and smooth for the user to perform the binding operation. The second surface 32 of the substrate 3 is provided with an inward-inclined groove 7 toward the bayonet 1. The groove allows the inner block of the double-block structure to be recessed in the groove, so that the second surface of the flexible binding fork after bending and clamping into the substrate will not have a convex platform due to the inner block, ensuring that the second surface is flat and easy to fit with loose-leaf paper for writing.

[0036] Recombination Figure 6-7As shown, the utility model also provides a loose-leaf notebook, including loose-leaf paper 8 and a loose-leaf binding device; wherein the loose-leaf binding device is an integrally formed structure and includes: a base plate 3, having a first surface 31 and a second surface 32 opposite to the first surface 31; a plurality of bayonet holes 1, arranged along the length direction of the base plate 3 and penetrating the first surface 31 and the second surface 32 of the base plate 3; a plurality of binding forks 2, arranged along the length direction of the base plate 3 and corresponding to the plurality of bayonet holes 1 one by one, and each binding fork 2 has a bottom end 21 and a top end 22 arranged oppositely, and the bottom end 21 is arranged on the first surface 31 of the base plate 3; after each binding fork 2 is bent in a direction away from the corresponding bayonet hole 1 and passes through the loose-leaf paper 8, the top end 22 is inserted into the corresponding bayonet hole 1 from the second surface 32 of the base plate 3 in a direction toward the first surface 31 to form a snap fit with the base plate 3, and after forming a snap fit with the base plate 3, the top end 22 and the bottom end 21 of each binding fork 2 are spaced apart in the width direction of the base plate 3. The base plate 3, the binding fork 2 and the card block 4 are made of silicone rubber. The top 22 of each flexible binding fork 2 is provided with two card blocks 4 that correspond to each other and are spaced apart. After the top 22 forms a snap fit with the base plate 3, the two card blocks 4 are respectively located on both sides of the thickness direction of the base plate 3. In this way, the card block at the top of the flexible binding fork after bending is snapped onto the base plate, and the tension of the silicone rubber material itself and the clamping of the two card blocks on the base plate are used to form a ring structure to bind the loose-leaf paper to form the loose-leaf notebook. If the loose-leaf notebook needs to remove or change the order of notes, the flexible binding fork can be withdrawn from the card slot in the loose-leaf binding device to easily complete the page change and then re-bind. It can also be reused after writing the notes and the inner core of the loose-leaf notebook can be replaced.
