Description

Technical Field

[0001] This utility model relates to the field of document binding technology, specifically a loose-leaf binding clip. Background Technology

[0002] Most existing loose-leaf notebooks are bound using metal binders, electroplated wire, plastic-coated wire, or spiral plastic rings. While electroplated wire, plastic-coated wire, and spiral plastic rings have low production costs, they are inconvenient for users to disassemble after binding. Metal binders, on the other hand, are easy to disassemble, but have higher production costs, are bulky, and rigid. When users write on the loose-leaf notebooks with their hands directly above the metal binders, they experience significant discomfort due to the pressure. Furthermore, metal binders have fixed dimensions, making them unsuitable for binding loose-leaf notebooks of different sizes. Therefore, we propose a loose-leaf binding clip. Utility Model Content

[0003] The purpose of this invention is to provide a loose-leaf binding clip to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A loose-leaf binding clip includes a soft strip, one end of which is integrally formed with a card holder, the outer wall of which is provided with a waist hole, the other end of which is integrally formed with a connecting rod, and the end of the connecting rod away from the soft strip is integrally formed with a locking rod. When the soft strip and the connecting rod are in their natural state, the length direction of the locking rod is perpendicular to the length direction of the waist hole.

[0006] As a further embodiment of this utility model, the width of the slot in the waist hole is adapted to the diameter of the connecting rod.

[0007] As a further embodiment of this utility model: the diameter of the clamping rod is greater than the groove width of the waist hole, and both ends of the clamping rod are chamfered, so that the end face diameter of the clamping rod is smaller than the groove width of the waist hole, and the length of the clamping rod is greater than the width of the clamping seat.

[0008] As a further embodiment of this utility model, the bottom of the card holder is provided with a card slot that is compatible with the card rod.

[0009] As a further embodiment of this utility model: a core rod is provided inside the clamping rod.

[0010] As a further embodiment of this utility model, it also includes a substrate, on which a plurality of through holes are formed along its length, the size of which is adapted to the cross-sectional size of the connection between the flexible strip and the card holder.

[0011] As a further improvement of this utility model: the top of the substrate has a groove on one side of each perforation, and the groove is adapted to the locking rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, the locking lever and connecting rod are passed through the binding hole on the loose-leaf binder so that the soft strip stays in the binding hole. Then, the soft strip and connecting rod are twisted so that the length direction of the locking lever is parallel to the length direction of the waist hole. The locking lever can then be easily passed through the waist hole, and the connecting rod stays in the waist hole. After releasing the soft strip and connecting rod, they will return to their original twisted angle under their own elasticity, so that the length direction of the locking lever is perpendicular to the length direction of the waist hole again. This completes the binding of the loose-leaf binder. The operation is simple and convenient. Moreover, since the binder is made of soft material, there will be no strong discomfort even if the hand is placed on the binder while writing. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1-3In this embodiment of the utility model, a loose-leaf binding clip includes a soft strip 1. One end of the soft strip 1 is integrally formed with a card holder 2. The outer wall of the card holder 2 is provided with a waist hole 3. The other end of the soft strip 1 is integrally formed with a connecting rod 4. The end of the connecting rod 4 away from the soft strip 1 is integrally formed with a locking rod 5. The materials of the soft strip 1, card holder 2, connecting rod 4 and locking rod 5 are preferably soft materials such as silicone, rubber, and TPE elastomer (Shore hardness 50-70HA). When the soft strip 1 and connecting rod 4 are in their natural state, the length direction of the locking rod 5 is perpendicular to the length direction of the waist hole 3.

[0020] By adopting the above-mentioned solution, when using this utility model, select an appropriate number of binding clips according to the size of the loose-leaf pages to be bound. Then, punch binding holes at appropriate positions on the edge of the loose-leaf pages to match the binding strip. Pass the clip 5 and connecting rod 4 through the binding holes so that the binding strip 1 stays in the binding holes. Then, twist the binding strip 1 and connecting rod 4 so that the length direction of the clip 5 is parallel to the length direction of the waist hole 3. Then, the clip 5 can be easily passed through the waist hole 3 and the connecting rod 4 stays in the waist hole 3. After releasing the binding strip and connecting rod 4, the twisted angle will be reset under the action of their own elasticity, so that the length direction of the clip 5 is perpendicular to the length direction of the waist hole 3 again. The binding of the loose-leaf pages is thus completed. The operation is simple and convenient. Moreover, since the binding clips are made of soft material, there will be no strong discomfort even if the hand is placed on the binding clips while writing.

[0021] When disassembling the loose-leaf pages, simply twist the locking lever 5 manually so that the length direction of the locking lever 5 is parallel to the length direction of the waist hole 3. Then pull the locking lever 5 outward to disengage the connecting rod from the waist hole 3. Finally, remove the soft strip 1, connecting rod 4, and locking lever 5 from the binding hole of the loose-leaf pages to complete the disassembly of the loose-leaf pages.

[0022] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the groove width of the waist hole 3 is adapted to the diameter of the connecting rod 4 so that the connecting rod 4 can pass through the waist hole 3.

[0023] Specific combination Figure 2 and Figure 3In one embodiment of this utility model, the diameter of the locking rod 5 is greater than the width of the slot of the waist hole 3, thereby reducing the possibility of the locking rod 5 passing through the waist hole 3 without human intervention. The length of the waist hole 3 is 1.05-1.5 times the length of the locking rod 5, so as to facilitate the locking rod 5 to pass through after twisting, and to avoid loosening due to excessive gap. Both ends of the locking rod 5 are chamfered, so that the diameter of the end face of the locking rod 5 is smaller than the width of the slot of the waist hole 3, thereby facilitating the manual passage of the locking rod 5 through the waist hole 3. The length of the locking rod 5 is 1.2-1.5 times the width of the card holder 2. This ratio can ensure that the locking rod 5 cannot pass through the waist hole 3 after resetting, improve the binding stability, further reduce the possibility of the locking rod 5 passing through the waist hole 3 without human intervention, and ensure the reliability of loose-leaf binding.

[0024] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the bottom of the card holder 2 is provided with a card groove 7 that is adapted to the card rod 5. After the card rod 5 is passed through the waist hole 3, the card rod 5 will adaptively be inserted into the card groove 7 under the action of the elasticity of the soft strip 1, so as to reduce the movement of the card rod 5 at the bottom of the card holder 2.

[0025] The clip 5 is equipped with a core rod 6, which is made of metal or hard plastic, such as stainless steel, ABS plastic, or nylon, to improve the strength of the clip 5 and prevent it from bending and deforming under strong pulling and passing directly through the waist hole 3. This further improves the reliability of the binder. The diameter of the core rod 6 is 1 / 3 to 1 / 2 of the diameter of the clip 5, which ensures strength without affecting the overall elasticity.

[0026] Specific combination Figure 1 In one embodiment of this utility model, the binding buckle also includes a base plate 8, on which a plurality of through holes 9 are provided along its length. The size of the through holes 9 is adapted to the cross-sectional size of the connection between the soft strip 1 and the card holder 2, so as to facilitate the installation of a plurality of soft strips on the base plate. The base plate 8 can be made of silicone material to improve the portability of the loose-leaf notebook. The base plate 8 can also be made of hard plastic to provide a certain support effect for the bound loose-leaf notebook.

[0027] Specific combination Figure 1 Based on the previous embodiment, the top of the substrate 8 is provided with a groove 10 on one side of each through hole 9. The groove 10 is adapted to the locking rod 5 so as to store the locking rod 5 passing through the waist hole 3 on the substrate 8, so that the bottom surface of the locking seat 2 can fit with the top surface of the substrate 8.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
