Description

Technical Field

[0001] This invention relates to the field of binding coil technology, and more specifically, to easily detachable binding coils. Background Technology

[0002] Binding refers to the post-printing processing of printed documents and booklets into a book, or the organization and binding of documents and receipts into a book. Common binding methods include perfect binding, spiral binding, and thread binding, among which spiral binding often involves thread binding.

[0003] Currently, when users need to put a page on the coil, they generally have to first break open the loops on the coil, then put the page on the loops, and finally close the loops. However, since the loops on the coil are continuous, users need to break open all the loops one by one before they can put the page on the loops. In order to prevent the page from coming off the loops during use, the loops are often closed very tightly, making it difficult to break open the loops when removing or installing the page.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an easy-to-assemble and disassemble binding coil to solve the technical problems mentioned in the background.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an easy-to-assemble binding coil, including a coil body, the coil body including a plurality of connecting rings, the connecting ring including a first arc-shaped block and a second arc-shaped block fixedly connected to each other, the first arc-shaped block being made of shape memory metal spring sheet, the inner arc surface of the first arc-shaped block being fixedly connected to an abutment block, when the first arc-shaped block is in its natural state, the abutment block and the inner arc surface of the second arc-shaped block are in contact with each other and a space for placing the document is formed between the abutment block, the first arc-shaped block and the second arc-shaped block, adjacent abutment blocks are connected to each other through connecting blocks, a rotating piece is rotatably connected to the side wall of the connecting block, the rotating piece being connected to the connecting block through a locking member.

[0007] The present invention is further configured such that the locking member includes a male buckle and a female buckle fixedly connected to the side wall of the connecting block and the rotating plate.

[0008] The present invention is further configured such that the rotating plate has a groove.

[0009] The present invention is further configured such that: a protrusion is provided at one end of the abutting block away from the first arc-shaped block; when the first arc-shaped block is in its natural state, the protrusion and the inner arc surface of the second arc-shaped block are in contact with each other, and the two sides of the contact point between the protrusion and the inner arc surface of the second arc-shaped block form a slot for inserting the document page.

[0010] The present invention is further configured such that: an extension block is fixedly connected to the side wall of the abutment block located on both sides of the outermost edge, and a pad block is fixedly connected to the extension block.

[0011] The present invention is further configured such that the surface of the pad is provided with anti-slip stripes.

[0012] The present invention is further configured such that a support block is fixedly connected to the outer wall of the extension block, and when the coil body is placed on the table, both the support block and the pad block are in contact with the table.

[0013] In summary, the present invention has the following beneficial effects:

[0014] All the first arc-shaped blocks can be straightened and tightened by pulling the rotating plate, without having to pull each one individually, making the operation more convenient. Furthermore, the abutment block between the first and second arc-shaped blocks can improve the structural strength of the connecting ring and prevent people from accidentally pressing on the connecting ring and causing damage.

[0018] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Easy-to-remove binding coils, such as Figures 1-2 As shown, the device includes a coil body, which comprises several connecting rings. Each connecting ring includes a first arc-shaped block and a second arc-shaped block fixedly connected to each other. The first arc-shaped block is made of shape memory metal spring sheet, and an abutment block is fixedly connected to the inner arc surface of the first arc-shaped block. When the first arc-shaped block is in its natural state, the abutment block and the inner arc surface of the second arc-shaped block are in contact with each other, and a space for placing a document is formed between the abutment block, the first arc-shaped block, and the second arc-shaped block. Adjacent abutment blocks are connected to each other through connecting blocks. A rotating piece is rotatably connected to the side wall of the connecting block, and a groove is provided on the rotating piece to facilitate pulling. The rotating piece is connected to the connecting block through a locking component, which includes a male and a female buckle fixedly connected to the side wall of the connecting block and the rotating piece. The connection and separation of the connecting block and the rotating piece can be achieved by the mutual engagement of the male and female buckles, which is simple and convenient.

[0022] like Figures 1-2 As shown, a protrusion is provided at the end of the abutment block away from the first arc-shaped block. When the first arc-shaped block is in its natural state, the protrusion and the inner arc surface of the second arc-shaped block fit together, and the two sides of the fit between the protrusion and the inner arc surface of the second arc-shaped block form a slot for inserting a document. When a single document needs to be removed, insert the document into the slot and pull the rotating piece to move the first arc-shaped block away from the second arc-shaped block. The protrusion on the abutment block and the inner arc surface of the second arc-shaped block will separate from each other. At this time, slide the document inserted into the slot so that it passes through the gap between the protrusion and the second arc-shaped block to remove the document from the connecting ring. There is no need to straighten the first arc-shaped block, which is more convenient.

[0023] like Figure 1 As shown, extension blocks are fixedly connected to the side walls of the two outermost abutment blocks, and pads are fixedly connected to the extension blocks. The pads prevent the connecting ring from contacting the desktop when the coil body is perpendicular to the desktop for page assembly or disassembly, thereby avoiding damage to the surface of the connecting ring. In addition, the surface of the pads is provided with anti-slip stripes, which can improve the anti-slip performance of the pads and prevent the position of the pads from shifting when the coil body is perpendicular to the desktop for page assembly or disassembly.

[0024] like Figure 1As shown, a support block is fixedly connected to the outer wall of the extension block. When the coil body is placed on the table, the support block and the pad are in contact with the table. When the coil body containing the pages is placed horizontally on the table, the support block and the pad can prevent the connecting ring from contacting the table, thereby avoiding friction between the connecting ring and the table and causing damage to the surface of the connecting ring. It can also prevent the coil body from shifting position.

[0025] The present invention is used normally as follows:

[0026] When a user needs to assemble or disassemble a page, they first select the rotating piece on the corresponding connecting block according to their needs. Then, using the pull groove, they pull the rotating piece to separate it from the side wall of the connecting block. Next, they pull the rotating piece away from the second arc-shaped block. Since the rotating piece is connected to the connecting block, the connecting block is connected to the abutment block, and the abutment block is connected to the first arc-shaped block, pulling the rotating piece will pull all the first arc-shaped blocks. Because the first arc-shaped blocks are made of shape-memory metal springs, pulling the rotating piece can straighten and tighten all the first arc-shaped blocks without having to pull each block individually. This makes operation more convenient. At the same time, the abutment block on the first arc block will separate from the second arc block. Then, people can align the through hole on the page with the second arc block and install the page on the second arc block. After the page is installed, pull the rotating piece towards the second arc block to restore the first arc block to its original shape. At this time, the abutment block will abut against the second arc block again, thus preventing the page from coming off the connecting ring during use. In addition, the abutment block between the first and second arc blocks can also improve the structural strength of the connecting ring and prevent people from accidentally pressing on the connecting ring and causing damage.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
