Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a composite material zipper pull auxiliary device, a zipper puller including the composite material zipper pull auxiliary device, and a zipper puller including the zipper puller. 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 pull disclosed in Chinese Invention Patent No. CN110811084B includes a pull tab auxiliary device. This device comprises a longitudinally elongated pull tab auxiliary part with a shoulder at one end, a head opposite the shoulder, and a neck connecting the shoulder and the head. When the pull tab auxiliary device is installed in the pull tab of the zipper pull, the pull tab auxiliary part is inserted into the mounting hole of the pull tab from the back. When the pull tab 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 pull tab. The pull tab auxiliary device is fixedly installed on the pull tab through the concave-convex structure. However, this pull tab auxiliary device is made entirely of silicone rubber, a single material, which makes the form of the pull tab auxiliary device relatively simple and reduces the design flexibility of the pull tab auxiliary device. 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 composite material pulling aid, which adopts a composite material structure and enriches the design of composite material pulling aids.

[0005] To achieve the above objectives, this utility model provides a composite material sheet pulling auxiliary device, comprising a connected device body and a device operating component, wherein the device body and the device operating component are made of different materials;

[0006] The main body of the device includes a primary injection molding part and a secondary injection molding part. The primary injection molding part is provided with a pull tab connecting part and a hanging protrusion protruding towards the secondary injection molding part. The device operating part has an operating fixing part embedded between the primary injection molding part and the secondary injection molding part. The operating fixing part is hung on the hanging protrusion and fixed between the primary injection molding part and the secondary injection molding part.

[0007] The composite material pull tab auxiliary device involved in this application assembles the entire composite material pull tab auxiliary device with the pull tab body to form a zipper pull tab through a pull tab connecting part, improving the ease of operation of pulling the zipper puller by pulling the zipper pull tab, while also enriching the design of the zipper puller and the zipper. In particular, the composite material pull tab auxiliary device sets the device body as a primary injection molded part and a secondary injection molded part on the primary injection molded part. This allows the device operating part, which is made of a different material than the device body, to be fixed between the primary and secondary injection molded parts while the secondary injection molded part is being formed. The device body and the device operating part are fixedly connected to form the composite material pull tab auxiliary device, making the composite material pull tab auxiliary device a composite material structure using two different materials. This enriches the design possibilities of the composite material pull tab auxiliary device and also broadens its application scenarios. Furthermore, during the process of forming a secondary injection molded part that is fixed to the primary injection molded part by re-injection molding on the primary injection molded part, the operating fixing part placed on the surface of the primary injection molded part is simultaneously fixed between the primary injection molded part and the secondary injection molded part, and the operating fixing part is also hung on the hanging protrusion, which greatly increases the fixing reliability between the main body of the appliance and the operating part of the appliance, and can prevent the operating part of the appliance from accidentally falling off the main body of the appliance after long-term use, making the composite material pull tab auxiliary appliance durable.

[0008] Furthermore, a preferred embodiment of the composite material pull tab auxiliary device is that the main body of the device is a TPU component, which gives the main body of the device good elastic deformation capability, facilitating the fixed installation of the pull tab connecting part of the main body of the device on the pull tab body.

[0009] Furthermore, a preferred embodiment of the composite material pulling aid is that the operating component of the aid is a rope component; or, the operating component of the aid is a belt component. Both rope and belt components are relatively conventional and low-cost, making the operating component simple and easy to implement, effectively reducing the cost of the composite material pulling aid.

[0010] Optionally, when the device operating component is a rope component, the rope component is directly hung on the hanging protrusion of the primary injection molding part, and then it can be injection molded again on the primary injection molding part to form a secondary injection molding part. When the device operating component is a belt component, the operating fixing part of the belt component has a hanging hole for the hanging protrusion to pass through. The belt component is hung on the hanging protrusion of the primary injection molding part through the hanging hole, and then it can be injection molded again on the primary injection molding part to form a secondary injection molding part.

[0011] Furthermore, a preferred embodiment of the composite material sheet-pulling auxiliary tool is that the primary injection molding section and the secondary injection molding section are arranged opposite to each other along the thickness direction of the composite material sheet-pulling auxiliary tool. This improves the compactness of the composite material sheet-pulling auxiliary tool in its width direction and enhances its aesthetics.

[0012] Furthermore, a preferred embodiment of the composite material pull tab auxiliary device is as follows: the pull tab connecting portion includes a connecting shoulder, a connecting head, and a connecting post. The connecting shoulder and the connecting head are arranged opposite to each other along the thickness direction of the composite material pull tab auxiliary device and are connected by the connecting post. An annular groove distributed on the outer periphery of the connecting post is formed between the connecting shoulder, the connecting head, and the connecting post. The secondary injection molding portion is fixed to the surface of the connecting shoulder facing away from the connecting head. In this way, the pull tab connecting portion can be reliably fixed at the mounting hole of the pull tab body, improving the connection reliability between the composite material pull tab auxiliary device and the pull tab body. It also achieves a detachable connection between the composite material pull tab auxiliary device and the pull tab body, enabling the replacement of the composite material pull tab auxiliary device.

[0013] This utility model provides another zipper pull tab, including a pull tab body with mounting holes and a composite material pull tab auxiliary device as described above, wherein the pull tab connecting part is connected to the pull tab body through the mounting holes.

[0014] This utility model provides another zipper pull, including a puller body and a zipper pull tab as described above, wherein the pull tab body is connected to the puller body.

[0015] As described above, the composite material zipper puller, zipper pull tab, and zipper screwdriver involved in this utility model have the following beneficial effects:

[0016] 1. Composite material pull tabs can improve the ease of operation of pulling the zipper puller, while also enriching the design of zipper pullers and zippers.

[0017] 2. Composite material pull tab auxiliary tool is a composite material structure using two different materials, which can enrich the design of composite material pull tab auxiliary tool and also broaden the application scenarios of composite material pull tab auxiliary tool.

[0018] 3. The main body of the composite material pull-tab auxiliary device is configured as a primary injection molded part and a secondary injection molded part on the primary injection molded part. During the process of injection molding the secondary injection molded part on the primary injection molded part to form a fixed secondary injection molded part, the operating fixing part placed on the surface of the primary injection molded part is fixed between the primary injection molded part and the secondary injection molded part. The operating fixing part is also hung on the hanging protrusion, which greatly increases the fixing reliability between the main body of the device and the operating part of the device. It can prevent the operating part of the device from accidentally falling off the main body of the device after long-term use, making the composite material pull-tab auxiliary device durable.

[0067] like Figure 1 and Figure 2 As shown, this utility model relates to the field of zipper technology, and in particular to a composite material zipper pull auxiliary device 10 for zippers, a zipper pull including the composite material zipper pull auxiliary device 10, and a zipper pull head including the zipper pull. Specifically, the zipper pull of this utility model includes a pull head body 70 and a zipper pull; the zipper pull of this utility model includes a pull head body 60 and a composite material zipper pull auxiliary device 10, with the pull head body 60 connected to both the pull head body 70 and the composite material zipper pull auxiliary device 10.

[0068] 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 body 70, the zipper tab body 60, and the composite material zipper tab auxiliary device 10 each correspond one-to-one with the length, width, and thickness directions of the zipper. 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.

[0069] 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.

[0070] like Figures 1 to 3 As shown, the zipper pull body 70 includes an upper wing plate 71 and a lower wing plate 72 arranged opposite each other, a tooth passage 73 formed between the upper wing plate 71 and the lower wing plate 72, and a pull tab mounting post 74 fixed to the upper surface of the upper wing plate 71. A portion of the chain teeth on the chain belt is accommodated in the tooth passage 73. Figure 1 , Figure 2 and Figure 4As shown, the front part of the pull tab body 60 is the pull head mounting part 62. The pull tab body 60 has a vertically penetrating column connection hole 63 in the pull head mounting part 62. The pull head mounting part 62 of the pull tab body 60 is hung on the pull tab mounting column 74 of the pull head body 70 through the column connection hole 63, connecting the front end of the pull tab body 60 to the pull tab mounting column 74, thereby installing the entire zipper pull tab on the upper surface of the pull head body 70. The rear part of the pull tab body 60 is the appliance mounting part 64. The pull tab body 60 has a vertically penetrating mounting hole 61 in the appliance mounting part 64. The mounting hole 61 can have various shapes, such as round holes, elliptical holes, rectangular holes, etc. In this embodiment, the mounting hole 61 is an elliptical hole, and the composite material pull tab auxiliary appliance 10 is connected to the pull tab body 60 at the mounting hole 61.

[0071] In particular, such as Figures 5 to 8 Or such as Figures 13 to 16 As shown, the composite material pull tab auxiliary device 10 of this utility model includes a device body 20 and a device operating part 30 fixedly connected, and the device body 20 and the device operating part 30 are made of different materials. The device body 20 includes a primary injection molding part 40 and a secondary injection molding part 50. The primary injection molding part 40 is injection molded first, and the secondary injection molding part 50 is injection molded later and injected onto the primary injection molding part 40. The primary injection molding part 40 and the secondary injection molding part 50 are made of the same material. The primary injection molding part 40 is provided with a pull tab connecting part 41 and a hanging protrusion 42 protruding toward the secondary injection molding part 50; the pull tab connecting part 41 is connected to the pull tab body 60 through a mounting hole 61, thereby installing the composite material pull tab auxiliary device 10 as a whole onto the pull tab body 60; as Figures 9 to 11 Or such as Figures 17 to 19 As shown, the appliance operating component 30 has an operating fixing part 31, which is embedded between the primary injection part 40 and the secondary injection part 50, and is hung on the hanging protrusion 42 and is also fixed between the primary injection part 40 and the secondary injection part 50.

[0072] In the production of the composite material pull tab auxiliary device 10 of this utility model, firstly, a primary injection molded part 40 is obtained by injection molding. This primary injection molded part 40 has a pull tab connecting part 41 and a hanging protrusion 42. Then, the operating fixing part 31 of the front end of the device operating part 30, which is made of a different material than the primary injection molded part 40, is hung on the hanging protrusion 42 of the primary injection molded part 40. Then, injection molding is performed again on the primary injection molded part 40 on which the device operating part 30 is hung, and on the side of the primary injection molded part 40 on which the operating fixing part 31 is hung, to obtain a secondary injection molded part 50. After the secondary injection molded part 50 is injection molded, it is fixed to the primary injection molded part 40. At the same time, the operating fixing part 31 of the device operating part 30 is embedded between the primary injection molded part 40 and the secondary injection molded part 50 and is fixed between the primary injection molded part 40 and the secondary injection molded part 50.

[0073] This application configures the main body 20 of the composite material pull tab auxiliary device 10 as a primary injection molding part 40 and a secondary injection molding part 50, which are formed by two injection molding processes. After the secondary injection molding part 50 is formed, an operating part 30 of a different material from the main body 20 is simultaneously fixed between the primary injection molding part 40 and the secondary injection molding part 50, thereby combining and fixing the different material main body 20 and the operating part 30 together. This makes the composite material pull tab auxiliary device 10 a composite material structure using two different material parts, making it easy to install components such as ropes and straps commonly used in zippers. This enriches the design possibilities of the composite material pull tab auxiliary device 10 and broadens its application scenarios. Furthermore, the composite material pull tab auxiliary device 10 is assembled with the pull tab body 60 via the pull tab connecting part 41 to form a zipper pull tab. The composite material pull tab auxiliary device 10 is provided for the user to grip, which can improve the ease of operation of pulling the zipper pull head by the zipper pull tab, and at the same time enrich the design of the zipper pull head and zipper. In particular, in the process of re-injecting the primary injection part 40 to form the secondary injection part 50 fixed to the primary injection part 40, the operating fixing part 31 placed on the surface of the primary injection part 40 is fixed between the primary injection part 40 and the secondary injection part 50, and the operating fixing part 31 is also hung on the hanging protrusion 42, which greatly increases the fixing reliability between the device body 20 and the device operating part 30, and can prevent the device operating part 30 from accidentally falling off the device body 20 after long-term use, making the composite material pull tab auxiliary device 10 durable. Furthermore, the setting of the holding protrusion 42 makes the fixing mating surface of the primary injection part 40 and the secondary injection part 50 a stepped surface, which can improve the fixing reliability between the primary injection part 40 and the secondary injection part 50.

[0074] Furthermore, the composite material pulling aid 10 has various structures for its operating component 30. Based on the different structures of the operating component 30, the composite material pulling aid 10 has several preferred embodiments. Two preferred embodiments of the composite material pulling aid 10 are provided below.

[0075] Example 1 of Composite Material Pulling Auxiliary Device

[0076] like Figure 5 and Figure 6 As shown, in Embodiment 1 of the composite material pull tab auxiliary device 10, the device operating component 30 is a rope component, which can be an elastic rope, nylon rope, etc. The rope component is a relatively conventional component and a commonly used part in zippers, resulting in low cost and making the device operating component 30 simple and easy to implement, effectively reducing the cost of the composite material pull tab auxiliary device 10. Before the secondary injection molding section 50, as... Figure 9 and Figure 10As shown, the front end of the rope component is directly hooked onto the hooking protrusion 42 on the upper side of the primary injection molding part 40, and then a second injection molding is performed above the primary injection molding part 40 and the rope component to form the secondary injection molding part 50. Figure 11 and Figure 12 As shown, the secondary injection molding part 50 is fixed on the upper surface of the primary injection molding part 40, and the operation fixing part 31, which is embedded between the primary injection molding part 40 and the secondary injection molding part 50, is fixed between the primary injection molding part 40 and the secondary injection molding part 50.

[0077] Example 2 of Composite Material Pulling Auxiliary Device

[0078] like Figure 13 and Figure 14 As shown, in Embodiment 2 of the composite material pulling aid 10, the operating component 30 is a belt component, preferably an elastic band, nylon belt, leather belt, or adhesive tape. Belt components are relatively conventional and low-cost, making the operating component 30 simple and easy to implement, effectively reducing the cost of the composite material pulling aid 10. Preferably, as... Figure 17 and Figure 18 As shown, the operating fixing part 31 of the belt component has a hanging hole 32 extending along the thickness direction of the belt component. The hanging hole 32 allows the hanging protrusion 42 to pass through. The belt component is hung on the hanging protrusion 42 of the primary injection molding part 40 through the hanging hole 32. Then, the primary injection molding part 40 and the belt component are injected again to form the secondary injection molding part 50. Figure 19 and Figure 20 As shown, the secondary injection molding part 50 is fixed on the upper surface of the primary injection molding part 40, and the operation fixing part 31, which has the front end of the component embedded between the primary injection molding part 40 and the secondary injection molding part 50, is fixed between the primary injection molding part 40 and the secondary injection molding part 50.

[0079] Furthermore, in Embodiments 1 and 2 of the above-mentioned composite material pulling auxiliary device 10, the structure of the main body 20 of the device is the same. For example... Figure 7 and Figure 8 As shown, or as Figure 15 and Figure 16 As shown, in the main body 20 of the appliance, the hanging protrusion 42 is fixedly disposed on the upper surface of the primary injection molding part 40, and preferably disposed at the middle position in the width direction of the primary injection molding part 40. The hanging protrusion 42 extends integrally upward from the upper surface of the primary injection molding part 40. The secondary injection molding part 50 is fixed on the upper side of the primary injection molding part 40. The hanging protrusion 42 is cylindrical. In the main body 20 of the appliance, the secondary injection molding part 50 and the primary injection molding part 40 are arranged vertically opposite to each other along the thickness direction of the composite material pull tab auxiliary appliance 10, so that the composite material pull tab auxiliary appliance 10 is relatively compact in its width direction. When viewed from the front of the composite material pull tab auxiliary appliance 10, the main body 20 of the appliance is not too wide in the left and right direction, thus improving the aesthetics.

[0080] Furthermore, in Embodiments 1 and 2 of the above-mentioned composite material pull tab auxiliary device 10, the preferred structure of the pull tab connecting portion 41 on the main body 20 of the device is as follows: Figure 7 and Figure 8 As shown, or as Figure 15 and Figure 16 As shown, the pull tab connecting portion 41 includes a connecting shoulder 43, a connecting head 44, and a connecting post 45. The connecting shoulder 43 and the connecting head 44 are arranged vertically opposite each other along the thickness direction of the composite material pull tab auxiliary tool 10. The connecting post 45 extends integrally downward from the lower surface of the connecting shoulder 43, and the connecting head 44 is integrally formed at the lower end of the connecting post 45, that is, the connecting shoulder 43 and the connecting head 44 are connected through the connecting post 45. The outer contour dimensions of the connecting shoulder 43 and the connecting head 44 are both larger than the outer contour dimension of the connecting post 45, so that an annular groove 46 is formed between the connecting shoulder 43, the connecting head 44, and the connecting post 45. The annular groove 46 is distributed on the outer periphery of the connecting post 45. The secondary injection molding portion 50 is fixed on the side surface of the connecting shoulder 43 facing away from the connecting head 44. During injection molding, the primary injection molding portion 40 with the pull tab connecting portion 41 is preferably formed in one step in both directions with half the shape. When installing the composite material pull tab auxiliary device 10 onto the pull tab body 60, it can be installed from the front or the back of the pull tab body 60. When installing from the front, simply align the connecting head 44 on the device body 20 with the mounting hole 61 on the pull tab body 60, then press the connecting head 44 in and through the mounting hole 61. When installing from the back, insert the rear end of the device operating part 30 upwards from the lower side of the pull tab body 60 into the mounting hole 61 until the connecting shoulder 43 is completely protruding from the mounting hole 61. After installation, as follows... Figure 1 and Figure 2 As shown, the connecting post 45 is accommodated in the mounting hole 61, and the circumferential solid portion of the mounting hole 61 engages in the annular groove. The connecting shoulder 43 abuts against the front of the pull tab body 60, and the connecting head 44 abuts against the back of the pull tab body 60, thereby fixing the pull tab connecting part 41 to the mounting hole 61 of the pull tab body 60, improving the connection reliability between the composite material pull tab auxiliary device 10 and the pull tab body 60. Simultaneously, this structure also enables a detachable connection between the composite material pull tab auxiliary device 10 and the pull tab body 60, allowing for the replacement of the composite material pull tab auxiliary device 10.

[0081] Preferably, the main body 20 of the appliance is a TPU component, which gives the main body 20 good elastic deformation ability as a whole, and facilitates the fixed installation of the pull tab connection part 41 of the main body 20 on the pull tab body 60.

[0082] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0083] 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.
