Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loose-leaf book binding, in particular to a binding ring buckle for a loose-leaf book. Background Art
[0002] A loose-leaf notebook is a commonly used stationery product, consisting of a cover, a binder or coil, and paper. It is a notebook in which the paper inside can be freely removed and added. The biggest difference from an ordinary notepad is that a loose-leaf notebook is more flexible to use, and the paper can be removed, replaced, combined, and easily organized.
[0003] Regarding the binding of loose-leaf books, most of the loose-leaf books are currently bound by binding rings, because this binding method is simple and has very low cost, there will be no paper jam when turning pages, and it is also convenient for users to replace the binding rings by themselves. In the prior art, the binding rings are usually composed of two components, and a plurality of half rings are respectively provided on the two components, and the two components are connected by the transfer of the shaft rod and the shaft hole. During the mutual rotation of the two components, the removal and addition of the paper on the loose-leaf book can be realized by locking or opening between the ends of the two half rings, and after the binding is completed by the binding rings, the paper inside the loose-leaf book can be freely turned around the binding rings. However, the two components of the above-mentioned binding rings need to be manually assembled, that is, the shaft rod is inserted into the shaft hole, and the manual assembly cost is high, resulting in a high ex-factory cost of the binding rings. Therefore, it is necessary to improve the structure of the binding rings. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a binding ring buckle for a loose-leaf book.
[0005] The technical solution adopted by the utility model is: a binding ring buckle of a loose-leaf book, one side of the loose-leaf book is provided with a plurality of binding holes spaced apart from each other along its length, and the binding ring buckle comprises:
[0006] The transfer part includes at least one set of rotating components, wherein the rotating components include two movable pieces, and the two movable pieces are mutually transferred along one side of their own length direction to form a transfer position;
[0007] There are two bars, which are respectively fixed on the sides of the two movable sheets away from the transfer position;
[0008] There are several half rings, which are fixed on the bar at intervals along the length of the bar;
[0009] The binding ring buckle has an open state and a binding state. In the process of switching from the open state to the binding state, the two movable pieces rotate around the transfer position, and the ends of the half rings enter the binding holes. The ends of the half rings on different rods are correspondingly engaged or connected to each other and cooperate together to lock the binding state.
[0010] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.
[0011] Preferably, the transition position is a thin portion, and the two movable sheets are completely connected along one side of their own length direction to form the thin portion.
[0012] Preferably, there are two groups of rotating components, which are respectively arranged on the upper and lower sides of the adapter portion, and the two bars and the two groups of rotating components are surrounded together to form a through opening.
[0013] Preferably, the cross-section of the movable sheet along the width direction is triangular.
[0014] Preferably, the half ring includes a first half ring and a second half ring, wherein there are two second half rings, which are respectively located at two ends of the bar, and there are several first half rings, which are all located between two second half rings.
[0015] Preferably, a clamping block and a clamping slot are provided on the same side of the end of the second half ring. In the binding state, the clamping block on the second half ring on one rod is clamped in the clamping slot on the second half ring on the other rod.
[0016] Preferably, a guiding slope is provided on one side of the clamping block.
[0017] More preferably, a protrusion is provided at the end of the first half ring on one rod, and a groove is provided at the end of the first half ring on the other rod, and in the binding state, the protrusion is matched and placed in the groove.
[0018] Compared with the prior art, the utility model has the following beneficial effects:
[0019] A transition part is set between the two bars, and the transition part is composed of two movable pieces. One side of the two movable pieces are connected to each other to form a transition position. The thickness of the transition position is relatively thin, so that the two movable pieces can rotate freely relative to each other. Since the bar and the movable piece are fixedly connected, and the half rings are fixed on the bar, when the two movable pieces rotate with each other and the ends of the second half ring are clamped with each other, the binding clip can be used to bind the loose-leaf book. After the binding ring is produced and formed, it does not need to be assembled manually afterwards, the labor cost is low, and the overall structure is stable and practical.

[0032] Specific implementation plan: see Figure 1-Figure 6 The utility model is a binding ring buckle for a loose-leaf book, one side of the loose-leaf book 6 is provided with a plurality of binding holes spaced apart from each other along its length, and the binding ring buckle comprises:
[0033] The transfer part 2 includes at least one set of rotating components, and the rotating components include two movable pieces 201. The two movable pieces 201 are mutually transferred along one side of their own length direction to form a transfer position 202;
[0034] There are two bars 1, which are respectively fixed on the sides of the two movable pieces 201 away from the transfer position 202;
[0035] There are several half rings, which are fixed on the bar 1 at intervals along the length of the bar 1;
[0036] The binding ring buckle has an open state and a binding state. In the process of switching from the open state to the binding state, the two movable pieces 201 rotate around the transfer position 202, and the ends of the half rings enter the binding holes. The ends of the half rings on different bars 1 are correspondingly engaged or connected to each other and cooperate together to lock the binding state.
[0037] As a preferred implementation of this embodiment, the transfer position 202 is a thin portion, and the two movable pieces 201 are completely connected along one side of their own length direction to form a thin portion.
[0038] In this embodiment, the thickness of the transfer position 202 is relatively thin. When the two movable pieces 201 rotate relative to each other through the rotating position, the transfer position 202 actually undergoes a certain degree of bending. However, due to its relatively thin thickness, even if it bends, it will not break after long-term use, and has a long service life.
[0039] See also Figure 2 It can be seen that in this embodiment, there are two groups of rotating components, which are respectively arranged on the upper and lower sides of the adapter portion, and the two bars 1 and the two groups of rotating components are surrounded together to form a through opening 5.
[0040] Here, the provision of the through opening 5 can further reduce the raw material cost of the binding ring. In addition, even if the through opening 5 is provided, the design of two rotating components can ensure the structural stability of the binding ring when the two movable pieces 201 rotate relative to each other around the rotating position in the open state and the bound state.
[0041] See also Figure 1 It can be seen that the cross section of the movable piece 201 along the width direction is a triangle. This design is to better realize the connection of the two sides of the movable piece 201 to the bar 1 and the transfer position 202 respectively.
[0042] The structure of the half rings and the connection states of the half rings in the binding state and the open state are described below. Note that this is prior art, so only a brief description is given here.
[0043] See also Figure 1-Figure 3 It can be seen that in this embodiment, the half ring includes a first half ring 3 and a second half ring 4, wherein there are two second half rings 4, which are respectively located at the two ends of the bar 1, and there are several first half rings 3, which are all located between the two second half rings 4.
[0044] In this embodiment, a clamping block 402 and a clamping slot 401 are provided on the same side of the end of the second half ring 4. In the binding state, the clamping block 402 on the second half ring 4 on one rod 1 is clamped in the clamping slot 401 on the second half ring 4 on the other rod 1.
[0045] Then, one side of the clamping block 402 is provided with a guiding slope.
[0046] More specifically, a protrusion 301 is provided at the end of the first half ring 3 on one rod 1 , and a groove 302 is provided at the end of the first half ring 3 on the other rod 1 . In the binding state, the protrusion 301 is matched and placed in the groove 302 .
[0047] When it is necessary to switch the open state to the binding state, first, the ends of each half ring on one of the bars 1 need to be aligned with each binding hole on the loose-leaf book 6 from the front side of the loose-leaf book 6. Note that since the binding ring buckle is symmetrically designed as a whole, the ends of each half ring on the other bar 1 are aligned with each binding hole on the loose-leaf book 6 from the back side of the loose-leaf book 6. Then, the binding ring buckle is closed through the adapter 2 (the specific principle has been explained above), and the ends of each half ring will enter the binding hole. Next, it is necessary to open the loose-leaf book 6, and the ends of each half ring can be seen. The two sides of the binding ring buckle are slightly squeezed in the direction of closing the binding ring buckle by hand. At this time, the block 402 on all the second half rings 4 on one bar 1 will be clamped in the slot 401 on all the second half rings 4 on the other bar 1. Continue to squeeze the two sides of the binding ring buckle by hand, and the clamping blocks 402 on the first half rings 3 on both sides are guided by the guide slopes and enter the clamping slots 401 to form an inverted clamping connection.
[0048] The binding ring buckle of a loose-leaf book of the utility model described above is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
