[0002] Cardboard books bound with binding twine are mostly used in the field of children's books. When using them, parents can untie the binding twine to take out a page of the cardboard book for individual use. After use, the page can be put back into place by rebinding it.

[0003] A search revealed that utility model patent CN215552053U discloses a bookbinding threading device, comprising: a strip-shaped base; a sliding groove disposed on the upper surface of the strip-shaped base and extending along the length direction of the strip-shaped base; the sliding groove being a through groove; a slider adapted to the shape of the sliding groove, capable of sliding back and forth within the sliding groove along its length direction; a rod vertically disposed on the upper surface of the slider; and a fixing structure including a thread groove and a fixing part, the thread groove extending from one end of the rod to the other end; the fixing part being disposed at the top of the rod for fixing the thread. This utility model's bookbinding threading device saves time in rearranging cardboard books and simplifies the threading process.

[0004] However, when the above-mentioned threading device is used to bind and thread books, the binding cord first needs to be pressed into the inside of the thread groove, and then the top of the binding cord is fixed with a sealing block. The operation is too cumbersome and the binding cord takes a long time to fix, making it too inconvenient to use in practice.

[0005] Therefore, it is necessary to invent a bookbinding threading device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a bookbinding threading device that can quickly fix the binding cord before threading the binding cord into cardboard books. It is easy to operate and has high fixing efficiency. In addition, the multiple clamping holes can accommodate binding cords of different specifications, thus having a wider range of applications. This solves the problem mentioned in the background art that the binding cord first needs to be pressed into the thread groove and then the top of the binding cord needs to be fixed with a sealing block, which is too cumbersome and time-consuming to fix the binding cord, and is too inconvenient in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a bookbinding threading device, comprising:

[0008] A base assembly for mounting multiple sets of threading assemblies;

[0009] Multiple sets of threading assemblies, each set including a threading rod, with a mounting groove at the top and a clearance groove on the right side of the threading rod communicating with the mounting groove. Two opposing rubber clamps, each with a right-angled triangular cross-section, are fixedly installed inside the mounting groove. Multiple clamping holes, distributed vertically and decreasing in radius, are shared inside the two rubber clamps. The inner walls of the clamping holes are roughened to increase friction.

[0010] Multiple binding cords, each of which is clamped and fixed to the inside of an adjacent binding hole by friction.

[0011] According to at least one embodiment of the bookbinding threading device of the present disclosure, the base assembly includes a base plate, and a positioning back plate for limiting the book by the rear of the cardboard pages is fixedly disposed on the top rear side of the base plate.

[0012] According to at least one embodiment of the bookbinding threading device of the present disclosure, the base assembly further includes a T-shaped connecting groove formed on the left side of the front of the substrate and extending to the left side of the top of the substrate, and a weight reduction groove formed on the right side of the bottom of the substrate.

[0013] According to at least one embodiment of the bookbinding threading device of the present disclosure, the threading assembly further includes a T-shaped connecting slider fixedly disposed at the bottom end of the threading rod, the T-shaped connecting slider being slidably disposed inside the T-shaped connecting groove.

[0014] According to at least one embodiment of the bookbinding threading device of the present disclosure, the threading assembly further includes two guide blocks fixedly disposed at the top of the threading rod and arranged symmetrically to each other.

[0015] According to at least one embodiment of the bookbinding threading device of the present disclosure, each of the two guide blocks having a first inclined surface for guiding the binding cord on the side close to each other, and a second inclined surface for guiding the cardboard book on the side far apart from each other.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a threading assembly to facilitate the fixing of binding cords before threading bindings in cardboard books. First, the binding cord is grasped and tensioned at its right end and middle using both hands. Then, the binding cord is moved into the mounting groove through the opening at the top. The binding cord is then pulled downwards until it slides along the inclined surfaces of the two rubber clamps to the corresponding thread-clamping holes and is clamped and fixed. Due to the clamping action of the two rubber clamps, the binding cord will not come out of the thread-clamping holes during subsequent binding and threading due to friction with the cardboard book, ensuring smooth binding and threading. Compared to existing technologies, this invention allows for quick fixing of binding cords before binding and threading, is easy to operate, and has high fixing efficiency. Furthermore, the multiple thread-clamping holes accommodate binding cords of different specifications, making it more widely applicable. Attached Figure Description

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a bookbinding threading device according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the base assembly 1 of a bookbinding threading device according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the threading component 2 of a bookbinding threading device according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the bookbinding and threading device disclosed herein may include components such as: a base assembly 1, multiple threading assemblies 2, and multiple binding cords 3.

[0031] like Figure 2 As shown in this disclosure, the base assembly 1 includes a base plate 11. A positioning back plate 12 for limiting the position of the base plate 11 by the back of the cardboard pages is fixedly disposed on the top rear side of the base plate 11. The base assembly 1 also includes a T-shaped connecting groove 13 opened on the left side of the front of the base plate 11 and extending to the left side of the top of the base plate 11, and a weight reduction groove 14 opened on the right side of the bottom of the base plate 11.

[0032] This allows the positioning backplate 12 to limit the position of the cardboard pages from behind, thereby facilitating the determination of the positions of multiple threading holes on the cardboard pages and adjusting the positions of multiple threading components 2.

[0033] like Figure 3As shown, in a preferred embodiment, any set of threading components 2 includes a threading rod 21. The top of the threading rod 21 is provided with an installation groove 22 and the right side of the threading rod 21 is provided with a clearance groove 23 that communicates with the installation groove 22. Two rubber clamping blocks 24 with right-angled triangular cross sections are fixedly provided inside the installation groove 22. The two rubber clamping blocks 24 are provided with a plurality of clamping holes 25 distributed vertically and decreasing in radius. The inner wall of the clamping hole 25 is provided with a rough surface to increase friction. Any binding rope 3 is clamped and fixed inside the adjacent clamping hole 25 by friction.

[0034] Therefore, to facilitate the fixing of the binding cord 3 before binding and threading of cardboard books, first use both hands to grasp and tighten the right end and middle of the binding cord 3. Then, move the binding cord 3 to the inside of the mounting groove 22 through the top opening of the mounting groove 22. Then, continue to pull the binding cord 3 downward until it slides along the inclined surface of the two rubber clamps 24 to the inside of the matching thread clamping hole 25 and is clamped and fixed. At this time, due to the clamping effect of the two rubber clamps 24, the binding cord 3 will not come out from the inside of the thread clamping hole 25 due to the friction of the cardboard book during subsequent binding and threading, so as to ensure the smooth binding and threading of cardboard books. Compared with the existing technology, the binding cord 3 can be quickly fixed before binding and threading of cardboard books. The operation is simple and has a high fixing efficiency. In addition, the setting of multiple thread clamping holes 25 can be used for binding cords 3 of different specifications, and the actual application range is wider.

[0035] like Figure 3 As shown in this disclosure, the threading assembly 2 also includes a T-shaped connecting slider 26 fixedly disposed at the bottom end of the threading rod 21, and the T-shaped connecting slider 26 is slidably disposed inside the T-shaped connecting groove 13.

[0036] Therefore, by allowing the T-shaped connecting slider 26 to slide inside the T-shaped connecting groove 13, the position of the threading rod 21 can be adjusted, thereby adjusting the distance between two adjacent threading rods 21 to adapt to the position of the threading holes on the cardboard book. At the same time, the corresponding number of threading components 2 can be selected to remain inside the T-shaped connecting groove 13 according to the number of threading holes on the cardboard book, and the excess threading components 2 are moved out through the front opening of the T-shaped connecting groove 13.

[0037] After adjusting the positions of multiple sets of threading components 2 and fixing multiple binding cords 3, the multiple cardboard pages are gradually lowered from directly above the multiple threading rods 21. During this process, the multiple threading rods 21 are inserted into the multiple threading holes on the cardboard pages. It should be noted that the radius of the threading hole is larger than the radius of the threading rod 21. After the multiple cardboard pages are placed, the binding cords 3 are pulled to pull them out from the inside of the thread clamping hole 25. Then, the two ends of the binding cords 3 are tied to secure the binding of the multiple cardboard pages.

[0038] like Figure 3 As shown, in a preferred embodiment, the threading assembly 2 further includes two guide blocks 27 fixedly disposed at the top of the threading rod 21 and arranged symmetrically to each other. The two guide blocks 27 are provided with a first inclined surface for guiding the binding cord 3 on the side that is close to each other, and a second inclined surface for guiding the cardboard book on the side that is far from each other.

[0039] Therefore, in the process of inserting the binding cord 3 into the inner side of the mounting slot 22, the first inclined surface can guide it, making it easier for it to enter. Similarly, in the process of attaching the cardboard pages to the outside of the multiple threading rods 21, the second inclined surface can guide the cardboard pages.

[0040] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0041] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
