Abstract
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 head including 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 has a puller auxiliary device, which includes 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 puller auxiliary device is inserted into the mounting hole of the puller puller from the back side. When the puller auxiliary part is fully inserted from the front side 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 side of the puller puller, thereby installing the puller auxiliary device on the puller puller. However, the existing technology has the following drawbacks: when installing the pull tab assist device, the pull tab assist part needs to pass through the mounting hole of the pull tab, which requires the pull tab assist part of the pull tab assist device to be designed as a thin structure that can pass through the mounting hole. The pull tab assist device can only use a pull tab assist part that is thinner than the mounting hole. The end of the pull tab assist part away from the neck is the grip part for the user to hold, which causes the shape of the grip part to be limited by the mounting hole. The grip part is usually a pointed shape, which restricts the design richness of the pull tab assist device. At the same time, when the user holds the pointed grip part, the contact surface is small, which reduces the user's operating feeling of pulling the pull head by holding the grip part. 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 can improve the user's handling of the pull tab auxiliary tool and enrich the design of the pull tab auxiliary tool.
[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 connecting part. The device body can pass through the mounting hole and is provided with a device shoulder. The device shoulder and the device head are arranged opposite to each other along the thickness direction of the pull tab body and are connected through the device connecting part. The device body is also provided with a deformable gripping part connected to the device shoulder. The gripping part is provided with a deformation-allowing part that allows it to deform.
[0006] When the gripping part is not deformed, the size of the gripping part is larger than the size of the mounting hole;
[0007] When the gripping part is deformed by the deformation-allowing part, the size of the gripping part is smaller than the size of the mounting hole.
[0008] In the zipper puller involved in this application, the gripping part for the user to hold on the puller aid is designed as a deformable structure, so that the outer contour of the gripping part has different dimensions. Specifically, under the combined action of external force and the deformation-allowing part, the gripping part deforms, and the gripping part is in a state where its size is smaller than the size of the mounting hole. At this time, the gripping part can pass through the mounting hole, thereby allowing the main body of the aid to pass through the mounting hole, thus facilitating the installation of the puller aid onto the puller body. After the puller aid is installed, when there is no external force or the applied external force is insufficient, the gripping part does not deform, and the gripping part is in a state where its size is larger than the size of the mounting hole. At this time, the gripping part cannot pass through the mounting hole, reliably preventing the gripping part from accidentally detaching from the mounting hole, thereby avoiding accidental separation of the puller aid from the puller body and improving the connection reliability of the two; at the same time, the gripping part returns to its large size state, providing a larger contact surface when the user holds the gripping part, improving the operating feel. In particular, this application allows the gripping part, which is larger than the mounting hole size when undeformed, to pass through the mounting hole by setting a deformation-allowing part. This reduces the constraint of the mounting hole on the shape of the gripping part, so that the gripping part is no longer limited to being designed as a pointed shape smaller than the mounting hole size. This allows for more design possibilities for the gripping part, enhancing the overall design richness of the zipper puller and enriching the design aesthetics of the zipper. Furthermore, a zipper body with a smaller mounting hole size can also be selected, giving the zipper body more options.
[0009] Further, in one embodiment of the pull tab auxiliary device, the pinching part is T-shaped, comprising a pinching main body extending along the length direction of the pull tab body, pinching protrusions fixed on both sides of the pinching main body along the width direction of the pull tab body, and a surface groove on the surface of the pinching main body. The pinching main body is connected to the shoulder of the device, and the surface groove constitutes the deformation-allowing part. When the two pinching protrusions of the pinching part are pinched in the width direction of the pull tab body, the surface groove allows the two pinching protrusions to approach each other, causing the pinching part to bend and deform, reducing its size in the width direction of the pull tab body, allowing it to pass through the mounting hole. After releasing the two pinching protrusions, the two pinching protrusions flatten out, and the width of the pinching part at the pinching protrusions is greater than the width of the mounting hole, preventing the pinching part from passing through the mounting hole.
[0010] Furthermore, in a preferred embodiment of the pull tab auxiliary device, the extending direction of the surface groove is consistent with the extending direction of the gripping main body, and both extend along the length direction of the pull tab body; the surface groove is located at the middle position of the gripping main body in the width direction of the pull tab body. This allows the gripping part to fold and deform along the surface groove, resulting in a smaller width at the gripping protrusion, making it easier for the gripping part to pass through the mounting hole.
[0011] Furthermore, in a second embodiment of the pull tab auxiliary device, the gripping part is O-shaped and has a through hollow portion, which constitutes the deformation-allowing part. When the gripping part is pinched in the width direction of the pull tab body, the hollow portion deforms the gripping part into a thin strip, making it easy to pass through the mounting hole. After releasing the gripping part, the maximum width of the gripping part, which returns to an O-shape, is greater than the width of the mounting hole, preventing the gripping part from passing through the mounting hole.
[0012] Furthermore, in Embodiment 3 of the pull tab auxiliary device, the pinching part is flat and flexible, and the flat shape of the pinching part constitutes the deformation-allowing part. When the pinching part is pinched and bent in the width direction of the pull tab body, the cross-section of the pinching part becomes an arc segment, thereby reducing the width of the pinching part and allowing it to pass through the mounting hole. After releasing the pinching part, the width of the pinching part, which returns to its flat shape, is greater than the width of the mounting hole, thus preventing the pinching part from passing through the mounting hole.
[0013] Further, in Embodiment 4 of the pull tab auxiliary device, the gripping part includes a gripping main body extending along the width direction of the pull tab body and at least one connecting strap. The gripping main body is a strip extending along the width direction of the pull tab body, and the at least one connecting strap connects the gripping main body and the shoulder of the device, constituting the deformation-allowing part. In the width direction of the pull tab body, the width of the gripping main body is greater than the width of the mounting hole, preventing the gripping main body from passing through the mounting hole when it is directly facing it; however, the connecting strap allows the gripping main body to be positioned sideways to the mounting hole, in which case the gripping part can pass through the mounting hole.
[0014] Furthermore, in Embodiment 5 of the pull tab auxiliary device, the pinching part has an inner hole, which constitutes the deformation-allowing part. When the pinching part is not deformed, its maximum width is greater than the width of the mounting hole, preventing it from passing through. After the pinching part is pinched, its inner hole allows the pinching part to narrow in its width direction; for example, the outer contour of the pinching part's cross-section can be deformed from an ellipse or rectangle to a circle, allowing the pinching part to pass through the mounting hole.
[0015] Furthermore, in Embodiment Six of the pull-tab auxiliary device, the gripping part is entirely an elastic body, which constitutes the deformation-allowing part. When the gripping part is not deformed, its maximum width is greater than the width of the mounting hole, preventing it from passing through. After the gripping part is pinched, the elastic gripping part can deform as a whole, narrowing in its width direction. For example, the outer contour of the gripping part's cross-section can deform from an ellipse or rectangle to a circle, allowing the gripping part to pass through the mounting hole.
[0016] Further, in embodiment seven of the pull tab auxiliary device, the gripping part includes a gripping main body extending along the length direction of the pull tab body, and at least one claw portion fixed to the outer periphery of the gripping main body. The gripping main body is connected to the shoulder of the device, and a gap is formed between the gripping main body and the claw portion. This gap allows the claw portion to move closer to the gripping main body, and the gap constitutes the deformation-allowing part. When the claw portion is gripped in the width direction of the pull tab body, the claw portion moves closer to the gripping main body, and the width of the gripping part at the claw portion decreases, allowing the gripping part to pass through the mounting hole. After releasing the claw portion, the claw portion unfolds outward and resets, and the width of the gripping part at the claw portion is greater than the width of the mounting hole, preventing the gripping part from passing through the mounting hole.
[0017] Furthermore, the surface of the gripping part is fixed with a logo, which enriches the design of the zipper pull and enhances brand recognition.
[0018] Furthermore, the main body of the device is positioned adjacent to the front of the zipper pull body, and the head of the device is positioned adjacent to the back of the zipper pull body. This means the entire front of the main body is exposed to the zipper pull, making it easier to design shapes on the front of the main body and enriching the design of the zipper pull. Simultaneously, the zipper pull auxiliary device is made of TPU, and the entire auxiliary device possesses a certain degree of elastic deformation characteristics, making it easier to install the auxiliary device onto the zipper pull body.
[0019] 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.
[0020] As described above, the zipper pull tab and zipper screwdriver of this utility model have the following beneficial effects:
[0021] 1. The deformation-allowing part allows the gripping part to be in a state where its size is smaller than the size of the mounting hole, thereby allowing the main body of the device to pass through the mounting hole and conveniently install the pull tab auxiliary device on the pull tab main body.
[0022] 2. After the pull tab auxiliary device is installed, the gripping part is in a state where its size is larger than the size of the mounting hole. The gripping part cannot pass through the mounting hole, reliably preventing the gripping part from accidentally detaching from the mounting hole, thereby avoiding accidental separation of the pull tab auxiliary device from the pull tab body and improving the connection reliability of the two; at the same time, it can provide a larger contact surface when the user holds the gripping part, improving the operation feel.
[0023] 3. This application allows the gripping part, which is larger than the size of the mounting hole when it is not deformed, to pass through the mounting hole by setting a deformation-allowing part. This reduces the constraint of the mounting hole on the shape of the gripping part, so that the gripping part is no longer limited to being designed as a pointed shape smaller than the size of the mounting hole. This allows the gripping part to have a richer design, improves the overall design richness of the zipper puller, and better enriches the design sense of the zipper.
[0024] 4. By deforming the gripping part to allow it to pass through a small mounting hole, a pull tab body with a smaller mounting hole size can be selected, giving the pull tab body more options. Attached Figure Description

[0091] This utility model relates to the field of zipper technology, specifically to a zipper pull tab and zipper screwdriver for zippers.
[0092] 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 1In 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.
[0093] 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.
[0094] 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... Figure 1 , Figure 2 and Figure 4 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 , Figure 2 and Figure 5 As shown, the zipper pull includes a pull body 10 and a pull auxiliary tool 20. The length, width, and thickness directions of the pull body 10 and the pull auxiliary tool 20 correspond one-to-one with the length, width, and thickness directions of the zipper. The front part of the pull body 10 is the pull head mounting part 12. The pull body 10 has a vertically penetrating column connection hole 13 in the pull head mounting part 12. The pull head mounting part 12 of the pull body 10 is sleeved on the pull head mounting column 64 of the pull head body 60 through the column connection hole 13, connecting the front end of the pull body 10 to the pull head mounting column 64, thereby installing the zipper pull as a whole on the upper surface of the pull head body 60. The rear part of the pull body 10 is the tool mounting part 14. The pull body 10 has a vertically penetrating mounting hole 11 in the tool mounting part 14. The mounting hole 11 can have various shapes, such as a round hole, an elliptical hole, or a rectangular hole; in this embodiment, the mounting hole 11 is an elliptical hole. The front end of the pull tab auxiliary device 20 is connected to the pull tab body 10 at the mounting hole 11; preferably, the pull tab auxiliary device 20 and the pull tab body 10 are detachably connected, so that the pull tab auxiliary device 20 can be replaced.
[0095] like Figure 6a and Figure 6bAs shown, the pull tab assist device 20 includes a device body 30, a device head 40, and a device connecting part 50. The device body 30 extends in the front-rear direction and can pass through the mounting hole 11. A device shoulder 31 is provided at the front end of the device body 30. The device shoulder 31 and the device head 40 are arranged opposite each other along the thickness direction of the pull tab body 10, and are connected by the device connecting part 50. The device connecting part 50 is columnar, and its size is smaller than that of the device shoulder 31 and the device head 40, so that the device shoulder 31, the device head 40, and the device connecting part 50 form an annular groove 70, which is distributed on the outer periphery of the device connecting part 50. When the pull tab assist device 20 is installed with the pull tab body 10, as... Figure 3 As shown, the rear end of the appliance body 30 is inserted upwards from the lower side (i.e., the back side) of the pull tab body 10 into the mounting hole 11, so that the entire appliance body 30 extends upwards through the mounting hole 11; at this time, as... Figure 2 As shown, the connecting part 50 is accommodated in the mounting hole 11. The solid portion around the mounting hole 11 engages in the annular groove 70 of the pull tab auxiliary device 20. The shoulder 31 of the device abuts against the front of the pull tab body 10, and the head 40 of the device abuts against the back of the pull tab body 10, thereby connecting the pull tab auxiliary device 20 and the pull tab body 10, and assembling the two into a zipper pull tab. Of course, in other embodiments, the rear end of the device body 30 can also be inserted downwards into the mounting hole 11 from the upper side (i.e., the front side) of the pull tab body 10, so that the entire device body 30 extends downwards from the mounting hole 11. In this case, after the pull tab auxiliary device 20 is installed, the shoulder 31 of the device abuts against the back of the pull tab body 10, and the head 40 of the device abuts against the front of the pull tab body 10.
[0096] like Figures 1 to 3 As shown, this application employs a method where the pull tab auxiliary device 20 is installed from the back side of the pull tab body 10. After installation, the device body 30 is positioned close to the front of the pull tab body 10, and the device head 40 is positioned close to the back of the pull tab body 10. Thus, the entire front of the device body 30 is exposed to the zipper pull tab, making it easier to design the shape on the front of the device body 30 and enriching the design of the zipper pull tab.
[0097] In particular, such as Figure 6a and Figure 6bAs shown, the main body 30 of the appliance also has a gripping part 32 for the user to hold. The front end of the gripping part 32 is connected to the rear end of the shoulder part 31 of the appliance. The gripping part 32 is provided with a deformation-allowing part 33, which allows the gripping part 32 to deform, so that the outer contour of the cross-section of the gripping part 32 has different dimensions; or, in other words, the deformation of the gripping part 32 is achieved by the deformation of the deformation-allowing part 33, so that the gripping part 32 has a size that can pass through the mounting hole 11 and a size that cannot pass through the mounting hole 11. Specifically, when the gripping part 32 is not deformed, the size of the gripping part 32 is larger than the size of the mounting hole 11, and at this time the gripping part 32 cannot pass through the mounting hole 11; when the gripping part 32 is deformed by the deformation-allowing part 33, the size of the gripping part 32 is smaller than the size of the mounting hole 11, and at this time the gripping part 32 can pass through the mounting hole 11. The shoulder part 31 of the appliance can always pass through the mounting hole 11.
[0098] Thus, when the pull-tab auxiliary tool 20 is installed on the pull-tab body 10, the user holds the gripping part 32 and applies force to the gripping part 32, such as... Figure 6c As shown, under the combined action of external force and deformation allowable part 33, the gripping part 32 will deform, so that the gripping part 32 is in a state where its size is smaller than the size of the mounting hole 11. In this state, the gripping part 32 is pushed upward through the mounting hole 11, so that the entire appliance body 30 passes through the back of the mounting hole 11 from the front, thereby conveniently installing the pull tab auxiliary appliance 20 on the pull tab body 10. After the pull tab assist device 20 is installed, the user releases the gripping part 32, and the external force applied to the gripping part 32 disappears; or, even if the user holds the gripping part 32, but the force applied to the gripping part 32 is insufficient to deform the gripping part 32, the gripping part 32 returns to its undeformed state, which means that the gripping part 32 is in a state where its size is larger than the size of the mounting hole 11. In this state, the gripping part 32 cannot pass through the mounting hole 11, reliably preventing the gripping part 32 from accidentally detaching from the mounting hole 11, thereby preventing the pull tab assist device 20 from accidentally separating from the pull tab body 10 and improving the connection reliability of the two; at the same time, the gripping part 32 returns to its large size state, and the user has a larger contact surface when holding the gripping part 32, improving the operation feel.
[0099] In particular, this application incorporates a deformation-allowing portion 33 that allows the gripping portion 32 to deform, enabling it to have dimensions that allow it to pass through the mounting hole 11 as well as dimensions that prevent it from doing so. This means the gripping portion 32 is no longer limited to a narrow shape smaller than the mounting hole 11; it can be designed in various shapes, reducing the constraint of the mounting hole 11 on its shape and allowing for more diverse designs. This enhances the overall design richness of the zipper puller 20 and enriches the zipper's design aesthetics. Furthermore, a zipper body 10 with a smaller mounting hole 11 can also be used, providing more options for the zipper body 10.
[0100] This application provides multiple embodiments of the pull-tab aid 20 based on different shapes of the gripping part 32. Several preferred embodiments of the pull-tab aid 20 are provided below.
[0101] Example 1 of the film pulling auxiliary device 20
[0102] like Figures 6a to 6c As shown, in Embodiment 1 of the pull tab assist device 20, the gripping part 32 is T-shaped. The gripping part 32 includes a gripping main body 321 extending back and forth along the length direction of the pull tab body 10, gripping protrusions 322 fixed on the left and right sides of the rear end of the gripping main body 321 along the width direction of the pull tab body 10, and a surface groove 323 provided on the surface of the gripping main body 321. The gripping main body 321 extends backward integrally from the rear end of the device shoulder 31. The surface groove 323 constitutes a deformation-allowing part 33. The surface groove 323 is preferably a V-shaped groove or a U-shaped groove. When installing the pull tab assist device 20, the user grips the two gripping protrusions 322 on the left and right sides in the width direction of the pull tab body 10, such as... Figure 6c As shown, under the action of the surface groove 323, the two pinching protrusions 322 move closer to each other, and the T-shaped pinching part 32 is bent and deformed, as... Figure 6d As shown; at this time, the width of the T-shaped gripping part 32 decreases and becomes smaller than the width of the mounting hole 11. The T-shaped gripping part 32 passes through the mounting hole 11 in this bent and deformed state. After the gripping part 32 passes through the mounting hole 11, the entire pull tab auxiliary tool 20 is rotated 180° in the mounting hole 11, and the tool head 40 is rotated to the back of the pull tab body 10. After the gripping part 32 passes upward through the mounting hole 11, the user releases the two gripping protrusions 322, and the two gripping protrusions 322 flatten out in the left and right directions. The width of the gripping part 32 at the gripping protrusions 322 is greater than the width of the mounting hole 11, so the gripping part 32 cannot pass through the mounting hole 11, thus restricting the gripping part 32 from falling out of the mounting hole 11. At the same time, when the user holds the T-shaped gripping part 32, the T-shaped gripping part 32 can provide a larger contact surface, improving the operating feel.
[0103] Preferably, the surface groove 323 can be provided on the front side of the gripping main body 321, in which case the gripping part 32 is bent upwards. Alternatively, the surface groove 323 can be provided on the back side of the gripping main body 321, in which case the gripping part 32 is bent downwards. In this embodiment, as... Figure 6c As shown, the surface groove 323 is located on the back of the gripping main body 321 to avoid affecting the front design of the gripping main body 321. Simultaneously, the extension direction of the surface groove 323 is consistent with the extension direction of the gripping main body 321, both extending forward and backward. Furthermore, the surface groove 323 is positioned in the middle of the gripping main body 321 in the left-right direction. Therefore, when the T-shaped gripping part 32 is bent and deformed, it folds along the surface groove 323. The deformed gripping part 32 has a smaller width at the gripping protrusion 322, making it easier for the gripping part 32 to pass through the mounting hole 11.
[0104] Example 2 of the film pulling auxiliary device 20
[0105] like Figure 7a and Figure 7b As shown, in Embodiment 2 of the pull tab assist device 20, the gripping part 32 is O-shaped and has a through hollow part 324. The hollow part 324 constitutes a deformation-allowing part 33. The O-shaped gripping part 32 is a flat shape with a small thickness, and the gripping part 32 extends integrally backward from the rear end of the device shoulder 31. When installing the pull tab assist device 20, the user holds the gripping part 32 and pinches it from the left and right sides, as shown. Figure 7b As shown, the hollow portion 324 in the middle of the pinching portion 32 deforms the pinching portion 32 into a thin strip, as... Figure 7c and Figure 7d As shown; at this time, the width of the slender gripping part 32 is less than the width of the mounting hole 11, and the O-shaped gripping part 32 passes through the mounting hole 11 in this elongated and deformed state. After the gripping part 32 is released, the maximum width of the O-shaped gripping part 32 is greater than the width of the mounting hole 11, and the gripping part 32 cannot pass through the mounting hole 11.
[0106] Example 3 of the film pulling auxiliary device 20
[0107] like Figure 8a and Figure 8b As shown, in Embodiment 3 of the pull tab assist device 20, the gripping part 32 is flat and flexible. The flat shape of the gripping part 32 constitutes a deformation-allowing part 33. The gripping part 32 extends integrally rearward from the rear end of the device shoulder 31. When installing the pull tab assist device 20, the user holds the gripping part 32 and pinches the left and right sides of the gripping part 32 in the width direction of the pull tab body 10, as shown. Figure 8b As shown, the gripping part 32 bends and deforms. In the bent state, the cross-section of the gripping part 32 is an arc segment, as shown... Figures 8c to 8eAs shown, the width of the gripping part 32 is reduced to be smaller than the width of the mounting hole 11, and the flat-shaped gripping part 32 passes through the mounting hole 11 in a bent and deformed state. After the gripping part 32 is released, the width of the flat-shaped gripping part 32 is greater than the width of the mounting hole 11, so the gripping part 32 cannot pass through the mounting hole 11.
[0108] Example 4 of the film pulling auxiliary device 20
[0109] like Figures 9a to 9c As shown, in Embodiment 4 of the pull tab assist device 20, the gripping part 32 includes a gripping main body 321 extending laterally along the width direction of the pull tab body 10, and two connecting straps 325; the two connecting straps 325 are symmetrically arranged left and right and are both connected between the gripping main body 321 and the device shoulder 31; the connecting straps 325 constitute a deformation-allowing part 33, which can change the relative position of the gripping main body 321 with respect to the device shoulder 31. The gripping main body 321 is a strip-shaped piece extending laterally along the width direction of the pull tab body 10; in the left-right direction, the width of the gripping main body 321 is greater than the width of the mounting hole 11, so when the gripping main body 321 is directly facing the mounting hole 11 in the up-down direction, the horizontal gripping main body 321 cannot pass through the mounting hole 11. However, as Figure 9d As shown, the cross-sectional dimension of the gripping main body 321 is smaller than the dimension of the mounting hole 11, and the gripping main body 321 is connected to the shoulder of the appliance 31 via a connecting strap 325. The connecting strap 325 allows the gripping main body 321 to change its relative position with respect to the shoulder of the appliance 31. Even if the gripping main body 321 is rotated 90° relative to the shoulder of the appliance 31, so that the end of the gripping main body 321 faces the mounting hole 11 in the vertical direction, the gripping part 32 passes through the mounting hole 11 in a lateral state. After the pull tab auxiliary appliance 20 is installed, the gripping part 32 is restored to a laterally extended state, restricting its passage through the mounting hole 11.
[0110] Preferably, such as Figure 9a As shown, both ends of the gripping main body 321 are integrally bent forward and extended with connecting protrusions 329. The rear end of the connecting strip 325 is fixed to the connecting protrusions 329. The fixing method can be injection molding.
[0111] Example 5 of the film pulling auxiliary device 20
[0112] like Figure 10a and Figure 10bAs shown, in Embodiment 5 of the pull tab assist device 20, the gripping part 32 is a flat shape with a small thickness and a hollow internal structure, that is, the gripping part 32 has an inner hole 326. The rear end of the inner hole 326 extends rearward through the rear end face of the gripping part 32, and the inner hole 326 constitutes a deformation-allowing part 33. The gripping part 32 extends rearward integrally from the rear end of the device shoulder 31. The maximum width of the gripping part 32 when it is not deformed is greater than the width of the mounting hole 11, and it cannot pass through the mounting hole 11. When installing the pull tab assist device 20, the user holds the gripping part 32 and pinches the gripping part 32 in the width direction of the pull tab body 10. The inner hole 326 of the gripping part 32 allows the gripping part 32 to narrow in its width direction and become smaller than the width of the mounting hole 11, such as... Figure 10c and Figure 10d As shown, for example, the outer contour of the cross-section of the gripping part 32 is deformed from an ellipse or rectangle into a circle; as Figure 10e As shown, the gripping part 32 passes through the mounting hole 11 in a narrowed, deformed state. After the gripping part 32 is released, the gripping part 32, which returns to its flat shape, cannot pass through the mounting hole 11.
[0113] Preferably, such as Figure 10a As shown, the width of the gripping part 32 gradually increases in the direction away from the shoulder 31 of the appliance, and the width of the gripping part 32 is the largest at the rear end.
[0114] Example 6 of the film pulling auxiliary device 20
[0115] like Figure 11a and Figure 11b As shown, in Embodiment Six of the pull tab assist device 20, the gripping part 32 is a flat shape with a small thickness, and the gripping part 32 as a whole is an elastic body. The elastic body constitutes a deformation-allowing part 33, and the gripping part 32 extends backward integrally from the rear end of the shoulder part 31 of the device. The maximum width of the gripping part 32 when it is not deformed is greater than the width of the mounting hole 11, and it cannot pass through the mounting hole 11. When installing the pull tab assist device 20, the user holds the gripping part 32 and pinches the gripping part 32 in the width direction of the pull tab body 10. The elastic gripping part 32 can be deformed as a whole, and the whole becomes narrower in its width direction, and smaller than the width of the mounting hole 11, such as... Figure 11c and Figure 11d As shown, for example, the outer contour of the cross-section of the gripping part 32 is deformed from an ellipse or rectangle into a circle; as Figure 11e As shown, the gripping portion 32 of the elastomer passes through the mounting hole 11 in a compressed, deformed state. After the gripping portion 32 is released, the gripping portion 32, which returns to its flat shape, cannot pass through the mounting hole 11.
[0116] Preferably, such as Figure 11a As shown, the width of the gripping part 32 gradually increases in the direction away from the shoulder 31 of the appliance, and the width of the gripping part 32 is the largest at the rear end.
[0117] Example 7 of the film pulling auxiliary device 20
[0118] like Figure 12a and Figure 12b As shown, in Embodiment 7 of the pull tab assist device 20, the gripping part 32 includes a gripping main body 321 extending along the length direction of the pull tab body 10, and two protruding claws 327 fixed on the left and right sides of the gripping main body 321. The gripping main body 321 extends integrally rearward from the rear end of the device shoulder 31; the protruding claws 327 are inclined, forming a gap 328 between the gripping main body 321 and the protruding claws 327. The gap 328 allows the protruding claws 327 to move towards the gripping main body 321, and the gap 328 constitutes a deformation-allowing part 33; the two protruding claws 327 form a V-shaped structure. When installing the pull tab assist device 20, the user grips the two protruding claws 327 on the left and right sides in the width direction of the pull tab body 10, as shown. Figure 12a As shown, under the action of the empty area 328, both protruding claws 327 move towards the gripping main body 321, and the protruding claws 327 are bent and deformed, as... Figure 12c and Figure 12d As shown; at this time, the width of the gripping part 32 at the protruding claw part 327 decreases and becomes smaller than the width of the mounting hole 11. The gripping part 32 passes through the mounting hole 11 in a bent and deformed state, as shown. Figure 12e As shown. After the gripping part 32 extends upward through the mounting hole 11, the user releases the two protruding claws 327, and the two protruding claws 327 unfold and reset in the left and right direction. The width of the gripping part 32 at the protruding claws 327 is greater than the width of the mounting hole 11, so the gripping part 32 cannot pass through the mounting hole 11, thus restricting the gripping part 32 from disengaging downward from the mounting hole 11.
[0119] Furthermore, in embodiments one to seven of the above-mentioned pull-tab auxiliary device 20, a logo portion is fixedly provided on the front side of the pinching part 32. The logo portion can be as follows: Figure 8a The letters shown can also be printed, enriching the design of the zipper pull and enhancing brand recognition.
