Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a zipper pull tab and a zipper screw with the zipper pull tab. Background Technology

[0002] Zippers are widely used in everyday items such as clothing, bags, tents, and bedding, enabling the merging or separation of items. Typically, a zipper consists of a pair of fabric strips, teeth fixed to the inner edges of each strip, and a zipper pull. The zipper pull includes a main body mounted on the teeth and a pull tab mounted on its surface. By pulling the pull tab along the length of the zipper, the teeth engage or disengage, thus opening or closing the zipper. Furthermore, some existing zippers include a pull tab auxiliary device. One end of this auxiliary device is attached to the zipper pull tab, which enhances the ease of pulling the zipper pull and adds to the zipper's design aesthetics.

[0003] Prior art: The zipper puller disclosed in Chinese Invention Patent No. CN110811084B includes a puller auxiliary device. This device comprises a longitudinally elongated puller auxiliary part with a shoulder at one end, a head disposed opposite to the shoulder, and a neck connecting the shoulder and the head. When the puller auxiliary device is installed in the puller puller of the zipper puller, the puller auxiliary part of the device is inserted into the mounting hole of the puller puller from the back. When the puller auxiliary part is fully extended from the front of the mounting hole, the annular groove formed by the shoulder, head, and neck engages with the periphery of the mounting hole, and the head abuts against the back of the puller puller, thereby installing the puller auxiliary device onto the puller puller. However, the existing technology has the following drawbacks: when installing the pull tab auxiliary device, the pull tab auxiliary part needs to pass through the mounting hole of the pull tab, which requires the pull tab auxiliary part of the pull tab auxiliary device to be designed as a thin structure that can pass through the mounting hole. The pull tab auxiliary device can only use a pull tab auxiliary part that is thinner than the mounting hole. The thin pull tab auxiliary part restricts its own design richness, and the thin pull tab auxiliary part is also located on the front of the zipper pull tab, which ultimately restricts the overall design richness of the zipper pull tab. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a zipper pull tab that is conducive to improving the overall design richness of the zipper pull tab.

[0005] To achieve the above objectives, this utility model provides a zipper pull tab, including a pull tab body and a pull tab auxiliary device. The pull tab body is provided with a mounting hole. The pull tab auxiliary device includes a device body, a device head, and a device post. The device body has a device shoulder that is disposed opposite to the device head along the thickness direction of the pull tab body. The device post is connected between the device shoulder and the device head.

[0006] Of the device body, the device head, and the device column, only the device body can pass through the mounting hole; when the device body passes through the mounting hole from the front of the pull tab body, the device shoulder is close to the back of the pull tab body, the device column is accommodated in the mounting hole, and the device head is close to the front of the pull tab body.

[0007] The main body of the device has a gripping part that protrudes from the head of the device, and the front of the head of the device constitutes a decorative part.

[0008] In the zipper pull of this utility model, the main body of the device is designed to be the size and shape that can pass through the mounting hole, but the head of the device is designed to be the size and shape that cannot pass through the mounting hole. Thus, on the one hand, by restricting the head of the device from passing through the mounting hole, the pull tab auxiliary device can be connected to the main body of the pull tab at the mounting hole; on the other hand, since the head of the device does not need to pass through the mounting hole, its size and shape are not constrained by the size of the mounting hole, thereby giving the head of the device a larger and more flexible design. Furthermore, the head of the device is located on the front of the zipper pull, and the front of the head constitutes a decorative part on the front of the zipper pull, thus giving the front of the zipper pull a larger and more flexible design, thereby enhancing the overall design richness of the zipper pull.

[0009] Furthermore, the main body of the device also has a connecting portion, and the shoulder of the device, the connecting portion and the pinching portion are connected in sequence along the length direction of the zipper body; thus, in the length direction of the zipper body, the length of the main body of the device is greater than the length of the head of the device, and the pinching portion protrudes from the head of the device in the length direction of the zipper body, making it convenient for the user to close or open the zipper by holding the pinching portion and pulling the zipper pull along the length direction of the zipper.

[0010] Furthermore, the connecting part is inclined, so that the gripping part and the pull tab body are positioned opposite each other along the length of the pull tab body. This makes the gripping part and the pull tab body coplanar, allowing the zipper pull tab to be pulled straight along its length using the gripping part. This makes it easier for users to pull the zipper pull along the zipper length using a pull tab assist tool, thus improving operational convenience.

[0011] Furthermore, the outer periphery of the device head is circular, elliptical, or square, which gives the decorative part on the front of the device head a large area, making it convenient to set decorative structures on the decorative part, enhancing the design richness of the device head, and thus better enhancing the overall design richness of the zipper pull.

[0012] Furthermore, the pull tab body has a tool mounting portion, and the mounting hole extends through the tool mounting portion along the thickness direction of the pull tab body. The tool mounting portion is covered by the tool head. This increases the surface area of ​​the tool head, facilitating the installation of decorative structures on the decorative portion, and also more reliably restricts the tool head from passing through the mounting hole, ensuring reliable connection between the pull tab auxiliary tool and the pull tab body, and preventing the pull tab auxiliary tool from accidentally detaching from the mounting hole.

[0013] Furthermore, the pull tab auxiliary device is made of TPU. This gives the pull tab auxiliary device a certain degree of elastic deformation, making it easier to install on the pull tab body. Simultaneously, the TPU pull tab auxiliary device is a one-piece molded part, which facilitates injection molding and enhances its structural strength, making it durable and thus extending the lifespan of the zipper pull tab.

[0014] Furthermore, the dimensions of the shoulder and head of the device are both larger than the dimensions of the column, so that the shoulder, head, and column form an annular groove. The annular groove is distributed on the outer periphery of the column and engages with the circumferential solid portion of the mounting hole, reliably connecting the pull tab auxiliary device to the pull tab body.

[0015] This utility model also provides a zipper pull, including a puller body and a zipper tab as described above, wherein the tab body is connected to the puller body, thereby mounting the zipper tab on the puller body.

[0016] As described above, the zipper pull tab and zipper screwdriver of this utility model have the following beneficial effects:

[0017] In the zipper puller of this utility model, the main body of the device is designed to be the size and shape that can pass through the mounting hole, but the head of the device is designed to be the size and shape that cannot pass through the mounting hole. This allows the puller auxiliary device to connect with the main body of the puller at the mounting hole, while also ensuring that the size and shape of the head of the device are not constrained by the size of the mounting hole, thus giving the head of the device a larger and more free design. Furthermore, the head of the device is located on the front of the zipper puller, and the front part of the head is a decorative part on the front of the zipper puller, which in turn gives the front of the zipper puller a larger and more free design, thereby enhancing the overall design richness of the zipper puller.

[0049] This utility model relates to the field of zipper technology, specifically to a zipper pull tab and zipper screwdriver for zippers.

[0050] For ease of description, in the following embodiments, the directions are defined as follows: the length direction of the zipper is defined as the front-to-back direction, the width direction of the zipper is defined as the left-to-right direction, and the thickness direction of the zipper is defined as the up-down direction. The length, width, and thickness directions of the zipper pull correspond one-to-one with the length, width, and thickness directions of the zipper chain, and the length, width, and thickness directions of the zipper pull tab also correspond one-to-one with the length, width, and thickness directions of the zipper chain. Based on this, Figure 1 In the view shown, the top of the paper is the front direction, the bottom of the paper is the back direction, the left side of the paper is the left direction, the right side of the paper is the right direction, the front of the paper is the top direction, and the back of the paper is the bottom direction.

[0051] Typically, a zipper mainly consists of a pair of fabric strips arranged side by side, a toothed chain strap fixed to the inner edge of each fabric strip and extending back and forth, and a zipper pull, which is slidably mounted on the toothed chain strap. When the zipper pull moves forward, the pair of toothed chain straps engage, thereby closing the zipper; when the zipper pull moves backward, the pair of toothed chain straps disengage, thereby opening the zipper.

[0052] like Figure 1 and Figure 2 As shown, the zipper pull of this utility model includes a puller body 60 and a zipper pull tab. For example... Figures 1 to 3 As shown, the zipper pull body 60 includes an upper wing plate 61 and a lower wing plate 62 arranged opposite each other, a tooth passage 63 formed between the upper wing plate 61 and the lower wing plate 62, and a pull tab mounting post 64 fixed to the upper surface of the upper wing plate 61. A portion of the chain teeth on the chain belt is accommodated in the tooth passage 63. Figure 1 and Figure 2 As shown, the zipper pull includes a pull body 10 and a pull auxiliary device 20. The length, width, and thickness directions of the pull body 10 and the pull auxiliary device 20 correspond one-to-one with the length, width, and thickness directions of the zipper. Figure 4 As shown, the front section of the pull tab body 10 is the pull head mounting part 13. The pull tab body 10 has a vertically penetrating column connection hole 14 in the pull head mounting part 13. The pull head mounting part 13 of the pull tab body 10 is fitted onto the pull tab mounting column 64 of the pull head body 60 through the column connection hole 14, connecting the front end of the pull tab body 10 to the pull tab mounting column 64, thereby mounting the zipper pull tab as a whole onto the upper surface of the pull head body 60. The rear section of the pull tab body 10 is the appliance mounting part 12. The pull tab body 10 has a vertically penetrating mounting hole 11 in the appliance mounting part 12. The mounting hole 11 can have various shapes, such as round, elliptical, or rectangular. The front end of the pull tab auxiliary appliance 20 is connected to the pull tab body 10 at the mounting hole 11. Preferably, the pull tab auxiliary appliance 20 and the pull tab body 10 are detachably connected, allowing the pull tab auxiliary appliance 20 to be replaced.

[0053] like Figure 5 and Figure 6 As shown, the pull tab assist device 20 includes a device body 30, a device head 40, and a device post 50. The device body 30 has a device shoulder 31 and a gripping part 32 for the user to hold. The device shoulder 31 and the device head 40 are arranged opposite each other along the thickness direction of the pull tab body 10, with the device shoulder 31 located on the lower side and the device head 40 located on the upper side. The device post 50 connects the device shoulder 31 and the device head 40. The front of the device head 40 is the design surface, which constitutes the decorative part 41 that serves a decorative function. In particular, the device body 30 is designed to be the size and shape that can pass through the mounting hole 11, while the device head 40 is designed to be the size and shape that cannot pass through the mounting hole 11. Thus, among the three components of the pull tab assist device 20—the device body 30, the device head 40, and the device post 50—only the device body 30 can pass through the mounting hole 11.

[0054] When installing the pull tab auxiliary device 20 to the pull tab body 10, such as Figure 7 As shown, the rear end of the appliance body 30 is inserted downwards into the mounting hole 11 from the front of the pull tab body 10, and the appliance body 30 is then pushed downwards out of the mounting hole 11. After the appliance body 30 passes through the mounting hole 11 from the front of the pull tab body 10, the appliance body 30 is located on the back of the pull tab body 10. Since the appliance head 40 cannot pass through the mounting hole 11, the appliance head 40 is engaged with the front of the pull tab body 10, thereby connecting the pull tab auxiliary appliance 20 to the pull tab body 10 at the mounting hole 11, and assembling the pull tab auxiliary appliance 20 and the pull tab body 10 into a zipper pull tab. At this time, as... Figure 1 and Figure 2 As shown, the shoulder 31 of the tool abuts against the back of the zipper pull body 10, the post 50 of the tool is housed in the mounting hole 11, the head 40 of the tool abuts against the front of the zipper pull body 10, the gripping part 32 protrudes from the head 40, and the decorative part 41 on the front of the head 40 is exposed on the front of the zipper pull. When it is necessary to replace the zipper pull auxiliary tool 20, the zipper pull auxiliary tool 20 is pulled out from the mounting hole 11 from the front of the zipper pull body 10.

[0055] In the zipper pull involved in this application, because the tool head 40 is designed to be a size and shape that cannot pass through the mounting hole 11, the size of the tool head 40 is larger than the size of the mounting hole 11, and the size and shape of the tool head 40 are not constrained by the size of the mounting hole 11, thus allowing for a larger and more flexible design of the tool head 40. Simultaneously, the tool head 40 is located on the front of the zipper pull, and the front of the tool head 40 constitutes a decorative portion 41 located on the front of the zipper pull. The decorative portion 41 is also not constrained by the size of the mounting hole 11, thus allowing for a larger and more flexible design of the decorative portion 41. This enables the tool head 40 and the decorative portion 41 to adopt richer designs, thereby giving the front of the zipper pull a larger and more flexible design, enhancing the overall design richness of the zipper pull. Furthermore, the tool body 30 is designed to be a size and shape that can pass through the mounting hole 11, facilitating the installation and removal of the pull-pull auxiliary tool 20 at the mounting hole 11.

[0056] Preferably, the outer periphery of the appliance head 40 is circular, elliptical, or square, so that the upper surface of the appliance head 40 has a large surface area, which also means that the decorative part 41 on the front of the appliance head 40 has a large area, making it convenient to set decorative structures such as logos and patterns on the decorative part 41, thereby enhancing the design richness of the appliance head 40 and thus better enhancing the overall design richness of the zipper pull.

[0057] Furthermore, since the entire device mounting portion 12 at the rear of the pull tab body 10 is covered by the device head 40, the width of the device head 40 is greater than the width of the device mounting portion 12, and the length of the device head 40 is greater than the length of the device mounting portion 12. Thus, the device head 40 is designed to have a larger size, much larger than the size of the mounting hole 11. This increases the surface area of ​​the front of the device head 40, facilitating the installation of decorative structures on the decorative portion 41, and also more reliably restricts the device head 40 from passing through the mounting hole 11, ensuring the reliable connection between the pull tab auxiliary device 20 and the pull tab body 10, and preventing the pull tab auxiliary device 20 from accidentally detaching from the mounting hole 11.

[0058] Furthermore, such as Figure 6 As shown, the dimensions of the shoulder 31 and the head 40 are both larger than the column 50, so that the shoulder 31, the head 40 and the column 50 form an annular groove 34. The annular groove 34 is distributed on the outer periphery of the column 50 and engages with the solid part around the hole of the mounting hole 11, reliably connecting the pull tab auxiliary device 20 to the pull tab body 10.

[0059] Furthermore, such as Figure 5 and Figure 6As shown, the appliance body 30 also has a connecting portion 33. The appliance shoulder 31, the connecting portion 33, and the gripping portion 32 are connected sequentially from front to back along the length direction of the pull tab body 10. Thus, the appliance body 30 is designed as a flat, slender structure extending back and forth along the length direction of the pull tab body 10, facilitating the through-hole operation of the appliance body 30 in the mounting hole 11. In this way, the length of the appliance body 30 is greater than the length of the appliance head 40 along the length direction of the pull tab body 10. The gripping portion 32 protrudes from the rear side of the appliance head 40 along the length direction of the pull tab body 10, allowing the user to easily close or open the zipper by holding the gripping portion 32 and pulling the zipper pull along the length direction of the zipper. Specifically, as... Figure 2 and Figure 6 As shown, the connecting part 33 is inclined, extending upwards and backwards as a whole. This causes the gripping part 32, connected to the rear section of the connecting part 33, to be positioned higher relative to the shoulder 31 of the tool. The gripping part 32 is then set to be coplanar with the zipper pull body 10. The gripping part 32 and the zipper pull body 10 are then positioned opposite each other along the length of the zipper pull body 10, with the gripping part 32 located directly behind the zipper pull body 10. Because the gripping part 32 and the zipper pull body 10 are coplanar, the zipper pull can be pulled straight along the length of the zipper pull using the gripping part 32. This makes it easier for the user to pull the zipper pull along the length of the zipper using the zipper pull assist tool 20, thus improving operational convenience.

[0060] Furthermore, such as Figure 5 and Figure 6 As shown, the pull tab auxiliary device 20, comprising a device body 30, a device column 50, and a device head 40, is made of TPU. Thus, the pull tab auxiliary device 20 as a whole possesses a certain degree of elastic deformation characteristics, making it easier to install the pull tab auxiliary device 20 onto the pull tab body 10. Simultaneously, the TPU pull tab auxiliary device 20 is a one-piece molded part, which facilitates injection molding and enhances the structural strength of the pull tab auxiliary device 20 itself, making it durable and thus extending the service life of the zipper pull tab.

[0061] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
