Description

Technical Field

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

[0002] Loose-leaf notebooks are flexible and convenient. Pages can be added, deleted, or rearranged at will, making it easy to organize notes, materials, etc. They can also be categorized and bound according to different themes or subjects, making the content more organized and allowing users to quickly find and browse the information they need.

[0003] Existing loose-leaf notebooks include a clip and a cover, with the clip mounted on the cover. The clip includes a fixing bracket, a left clip, and a right clip. Each cover has a clip at the top and bottom, and only one clip on each clip can be unlocked; that is, only the left clip can be rotated and unlocked, or only the right clip can be rotated and unlocked. This means that the clips can only be unlocked one at a time, which is cumbersome and reduces efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a loose-leaf notebook in which the left and right clips on both sides of the fixed bracket can be rotated and unlocked. Therefore, both clips can be unlocked at the same time with both hands, which is very convenient and can improve the efficiency of use.

[0005] The technical solution of this utility model is to provide a loose-leaf notebook with the following structure, including a clamp and a cover. The clamp includes a fixing bracket, at least one first half-ring, and at least one second half-ring. The fixing bracket is connected to the cover. A first rotating shaft and a second rotating shaft are rotatably connected to both sides of the fixing bracket. One end of the first half-ring is connected to the first rotating shaft, and one end of the second half-ring is connected to the second rotating shaft. A locking structure is provided between the other ends of the first and second half-rings. The locking structure includes a protrusion and a snap-fit ​​groove. Both sides of the snap-fit ​​groove have an inlet, and the protrusion can be engaged into the snap-fit ​​groove from both inlets.

[0006] By adopting the above structure, the loose-leaf notebook of this utility model has the following advantages compared with the prior art:

[0007] Because the locking structure of the loose-leaf notebook of this utility model has inlet ports on both sides of the locking groove, the protrusion can be inserted into the locking groove from the inlet ports on both sides. Therefore, it is more flexible to use. Both hands can unlock two clamps at the same time, and one hand can also untie two rings at the same time. It is very convenient to use and greatly improves the efficiency of use.

[0008] As an improvement, a guide surface is provided on the side of the inlet near the fastening groove. With this structure, the protrusion smoothly engages with the fastening groove from the inlet due to the action of the guide surface, making it more convenient to use.

[0009] As an improvement, a first protrusion is provided on one side of the other end of the first half-ring, and a first fastening groove is provided at the other end of the second half-ring opposite the first protrusion. This structure is simple and easy to use.

[0010] As an improvement, a second locking groove is provided on one side of the other end of the first half-ring, the second locking groove being located inside the first protrusion; a second protrusion is provided on the other end of the second half-ring opposite the second locking groove, the second protrusion being located outside the first locking groove; when the first and second half-rings are closed, the first and second protrusions respectively engage with the first and second locking grooves. With this structure, there are two sets of locking mechanisms, resulting in a better locking effect.

[0011] As an improvement, two first half-rings are provided, with one end of each first half-ring connected to the first rotating shaft; two second half-rings are provided, with one end of each second half-ring connected to the second rotating shaft. With this structure, the design is more reasonable, and the two first half-rings or two second half-rings can be unlocked simultaneously by grasping them with the thumb and forefinger of one hand, making it very convenient to use.

[0012] As an improvement, the cover includes a front cover, a spine, and a back cover; the fixing bracket is connected to the spine; the front cover has a first through hole, and the back cover has a second through hole; the first half-ring and the second half-ring pass through the first through hole and the second through hole respectively and are then interlocked. With this structure, the first half-ring and the second half-ring are exposed outside the front and back cover, resulting in a more compact structure.

[0013] As an improvement, a third through hole is provided on the spine, which communicates with the first and second through holes. This structure allows for greater flexibility in the movement of the first and second half-rings due to the third through hole.

[0014] As an improvement, the fixing bracket is fixedly connected to the inner side of the spine, or the fixing bracket is fixedly connected to the outer side of the spine. This structure results in a more reasonable structural design.

[0015] As an improvement, at least one sidewall of the first through hole is provided with a first protrusion, and when the first half-ring and the second half-ring are engaged, the first protrusion is located below the first half-ring. With this structure, the first protrusion is limited by the first half-ring, and the front cover will not be blown up by the wind.

[0016] As an improvement, at least one sidewall of the second through hole is provided with a second protrusion. When the first half-ring and the second half-ring are engaged, the second protrusion is located below the second half-ring. With this structure, the second protrusion is limited by the second half-ring, and the rear cover surface will not be blown up by the wind. Attached Figure Description
