The use herein of the terms "and / or" includes any and all combinations of one or more of the associated listed items. Example 1
[0038] The following combines Figures 1 to 9 The embodiments of the application are described.
[0039] As Figure 1 , Figure 2 shown, the improved binder of the present embodiment includes a first clasp 1, a second clasp 2, a clamping base 3, and an opening member 4.
[0040] The first clasp 1 and the second clasp 2 have the same basic shape as the binder of the prior art, and have a clasp ring 11 and 21 for binding the binder, which can be closed or opened, and a bottom plate 12 and 22 of integral structure.
[0041] The first clasp 1 and the second clasp 2 are symmetrical and left-right combined, i.e. the bottom plates 12 and 22 of the two are left-right combined, and can be swung on the central axis a of the two combined to achieve the purpose of opening the clasp rings 11 and 21.
[0042] The clamping base 3 is clamped on both sides of the first clasp 1 and the second clasp 2, and at the same time exerts a clamping force on both sides of the first clasp 1 and the second clasp 2 in the direction of the central axis, so that the first clasp 1 and the second clasp 2 can be kept in a closed or opened state.
[0043] In the present embodiment, the opening member 4 is two, which are movably arranged below the end portions of the first clasp 1 and the second clasp 2, respectively, for applying an opening torque in the direction of the central axis a, so that the first clasp 1 and the second clasp 2 can be kept in a closed or opened state.
[0044] In order to achieve the above purpose, in combination with Figure 3As shown, the first buckle clip 1 and the second buckle clip 2 are provided with clamping grooves 13 and 23 on both sides of the bottom plates 12 and 22, and the clamping base 3 is clamped on both sides of the clamping grooves 13 and 23.
[0045] In combination Figure 4 As shown, in a further preferred embodiment, the clamping base 3 is in a "U" shape structure, and the clamping grooves are "V" shape through grooves provided on the side surfaces of the bottom plates 12 and 22 and parallel to the central axis a, so that the clamping base 3 can be slid into the clamping grooves from one end of the clamping grooves 13 and 23, and the clamping base 3 in the "U" shape structure can generate a certain elastic clamping force, that is, the clamping force can meet the requirements of keeping the first buckle clip 1 and the second buckle clip 2 closed, and at the same time, the clamping base 3 can have a certain deformation ability when the first buckle clip 1 and the second buckle clip 2 are opened, so as to meet the opening process.
[0046] The opening member 4 acts on the end of the clamping base 3 and acts on the central axis of the bottom plates 12 and 22 of the first buckle clip 1 and the second buckle clip 2, so as to overcome the clamping force of the clamping base 3 and open the first buckle clip 1 and the second buckle clip 2.
[0047] Specifically, in combination Figure 5 , Figure 6 , Figure 7 As shown, the opening member 4 includes an integrated opening handle 41 and an opening connecting rod 42, the opening connecting rod 42 is arranged on the end back of the first buckle clip 1 and the second buckle clip 2, and the opening handle 41 is arranged outside the end of the clamping base 3 and the first buckle clip 1 and the second buckle clip 2.
[0048] When the first buckle clip 1 and the second buckle clip 2 are opened, the opening handle 41 exposed outside the end of the clamping base 3 acts as a fulcrum on the end of the clamping base 3, and lifts the bottom plates 12 and 22 of the first buckle clip 1 and the second buckle clip 2 towards the central axis, so that the bottom plates 12 and 22 overcome the clamping force of the clamping base 3 and produce a torsional swing along the central axis a, so as to open the first buckle clip 1 and the second buckle clip 2.
[0049] As shown in Figure 6 , 7 The surface of the opening connecting rod 42 is provided with a buckle body 43, and the back surface of the first buckle clip 1 and / or the second buckle clip 2 is provided with a buckle groove 14 movably buckled with the buckle body 43.
[0050] In this embodiment, the buckle groove 14 is arranged at the central axis of the bottom plates 12 and 22, so that the opening connecting rod 42 can be movably arranged on the end back of the first buckle clip 1 and the second buckle clip 2.
[0051] In combination Figure 5 As shown, the end of the opening connecting rod 42 is in a triangular shape and abuts against the central axis, so that the force point of the opening connecting rod 42 is located between the bottom plates 12 and 22, and the first buckle clip 1 and the second buckle clip 2 are more labor-saving.
[0052] In combinationFigure 6 As shown, the opening linkage 42 has a bend 44 that is connected to the opening handle 41. When the first clip 1 and the second clip 2 are opened, the bend 44 is the fulcrum of the force.
[0053] A more preferred embodiment is that the ends of the first clip 1 and the second clip 2 have arc-shaped surfaces 15 that match the shape of the bend 44. Under normal conditions, the bend 44 fits tightly with the ends of the first clip 1 and the second clip 2.
[0054] Combination Figure 8 As shown, the back of the first clip 1 and the second clip 2 are provided with opposing stop rotating blocks 16 and 24 on both sides of the central axis.
[0055] Several stop-rotation blocks 16 and 24 are staggered. Each stop-rotation block has a protrusion extending on the edge of the opposing base plate. A pair of stop-rotation blocks between opposing base plates cooperate with each other and play a role in limiting rotation when the base plates 12 and 22 twist and swing. In this embodiment, at least two pairs of stop-rotation blocks are provided to make the structure balanced and stable.
[0056] Combination Figure 9 As shown, when the opening handle 41 is pressed, the opening member 4 is tilted at the end of the clamping base 3. When the tip of its opening link 42 pushes up the central axis of the base plates 12 and 22 of the first clip 1 and the second clip 2, the base plates 12 and 22 are twisted and swung under the clamping force of the clamping base 3, causing the first clip 1 and the second clip 2 to open to both sides.
[0057] In this embodiment, the first clip 1, the second clip 2, the clamping base 3, and the opening member 4 can all be formed by injection molding. Of course, the clamping base can also be formed by pressing iron material with elastic clamping deformation. This embodiment is not limited to this. Example 2
[0058] like Figure 10 As shown, in this embodiment, its opening structure is the same as that in Embodiment 1, also including a first clip 1, a second clip 2, a clamping base 3, and an opening member 4. In this embodiment, specifically, the number of clamping rings 11 and 21 on the first clip 1 and the second clip 2 can be 8 pairs, divided into upper and lower groups. In this embodiment, the upper 4 groups and the lower 4 groups are separated. In other embodiments, the number of clamping rings can be set as needed, and the grouping interval can be set or not set as needed. This embodiment is not limited to this.
[0059] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form; any person skilled in the art can smoothly implement the present application according to the drawings shown in the specification and the above description; however, any person skilled in the art can make slight changes, modifications and equivalent changes of the present application within the scope of the technical scheme of the present application, and the equivalent embodiments of the present application are still within the protection scope of the technical scheme of the present application.
