[0001] This utility model relates to the field of clothing design technology, and more specifically, to a double-zipper pull assembly. Furthermore, this utility model also relates to a zipper including the aforementioned double-zipper pull assembly. Background Technology
[0002] A double-ended zipper (also known as a double-ended closed-end zipper or an "O"-shaped closed-end zipper) is a type of zipper with two sliding tabs on a closed chain, allowing the zipper to remain fixed at both ends and open only from the middle. Typical applications include bags, tents, outdoor gear, and winter clothing where multiple openings are needed while keeping both ends closed. The two tabs of a double-ended zipper can be pulled from the middle towards either end or from either end towards the middle, enabling quick opening and closing from multiple points, making it convenient to access items in confined spaces or while seated.
[0003] Existing concealed double-closed zipper pulls use an integrated mold design, which presents problems such as difficulties in integrated mold production, easy detachment of assembled parts, and large size and length.
[0004] In conclusion, how to reduce production difficulty is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a double zipper head assembly accessory that can shorten the overall length without changing the structure of the zipper head body. The connection between the zipper head fixing accessory and the second zipper head body and the base can reduce the difficulty of production.
[0006] Another objective of this invention is to provide a zipper that includes the aforementioned double-slipper assembly.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation
[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] The core of this utility model is to provide a double-pull head assembly accessory, which has a simple structure, higher strength, and lower manufacturing difficulty.
[0040] Another core aspect of this invention is to provide a zipper that includes the aforementioned double-slipper assembly.
[0041] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0042] This application provides a dual-pull head assembly, comprising: a base 1, a first pull head body 3, a second pull head body 4, and a pull head fixing accessory 5;
[0043] The base 1 can accommodate at least two zipper heads, including the first zipper head body 3 and the second zipper head body 4, and is provided with at least one through hole 103 penetrating the base 1.
[0044] The first zipper head body 3 and the second zipper head body 4 are disposed on the base 1 with their heads facing each other, and at least one of the zipper head bodies is provided with a through hole 401 corresponding to the through hole 103;
[0045] The zipper head fixing accessory 5 passes through the through hole 401 and the through hole 103, and the zipper head fixing accessory 5 is used to connect the base 1 and the corresponding zipper head body.
[0046] For details, please refer to the appendix. Figure 1 The base 1 is provided with a through hole 103, which can penetrate the surface of the base 1. Taking two zipper heads as an example, only one of the first zipper head body 3 or the second zipper head body 4 is provided with a through hole 401. When the zipper head body is installed on the base 1, the through hole 103 and the through hole 401 can communicate. The zipper head fixing accessory 5 can pass through the through hole 401 and the through hole 103 in sequence and can be engaged with the bottom surface of the base 1, thereby realizing the positioning of the second zipper head body 4. Compared with the traditional accessory combination double-closed zipper head, this solution does not need to change the structure of the first zipper head body 3 or the second zipper head body 4. And because the zipper head fixing accessory 5 partially penetrates the zipper head, no additional fixing space is needed. Therefore, compared with other accessory combination double-closed zipper heads, it is shorter in length, smaller in size, and simpler in structure. It only requires the addition of the base 1, the through hole 401 on the second zipper head body 4, and the zipper head fixing accessory 5. The production cost is low, the mold opening is simple, the scrap rate of finished products is low, and the production difficulty is reduced.
[0047] Based on the above embodiment, a limiting member 2 is also included. The limiting member 2 is disposed on the base 1 and includes at least two limiting claw buckles 201. The limiting claw buckles 201 are respectively disposed on both sides of the first zipper head body 3. The limiting claw buckles 201 include a longitudinal limiting part 202 and a transverse limiting part 203. The longitudinal limiting part 202 is perpendicular to the base 1, and the transverse limiting part 203 is perpendicular to the longitudinal limiting part 202. The two transverse limiting parts 203 are arranged opposite to each other. Alternatively, the limiting member 2 has the same structure as the zipper head fixing accessory 5.
[0048] Specifically, the structure of the limiting member 2 can be found in the attached document. Figure 2Two limiting claw buckles 201 are provided. The lateral limiting parts 203 of the two limiting claw buckles 201 are parallel to the base body of the base 1, and the longitudinal limiting parts 202 are perpendicular to the base 1, so that the two limiting claw buckles 201 can present an encircling structure. The two limiting claw buckles 201 are located on both sides of the first zipper head body 3. The two limiting claw buckles 201 can fix the first zipper head body 3 in the first groove 101 to ensure the reliability of the structure. It should be noted that the limiting claw buckles 201 should have a certain elasticity to facilitate the first zipper head body 3 to be inserted into the first groove 101 and prevent the limiting claw buckles 201 from being damaged during the process of the first zipper head body 3 being inserted into the first groove 101.
[0049] Furthermore, when both the first slider body 3 and the second slider body 4 are provided with through holes 401, the limiting member 2 can be replaced by the slider fixing accessory 5, that is, the limiting member 2 and the slider fixing accessory 5 have the same structure.
[0050] Based on the above embodiment, the surface of the base 1 is provided with a first groove 101 and a second groove 102. The bottom shape and size of the first pull head body 3 are provided in accordance with the first groove 101. The limiting member 2 cooperates with the first groove 101 to prevent the first pull head body 3 from sliding. The bottom shape and size of the second pull head body 4 are provided in accordance with the second groove 102. The outer periphery of the second groove 102 is provided with a limiting protrusion 104 perpendicular to the base 1.
[0051] For details on the structure of base 1, please refer to the attached document. Figure 3 The surface of the base 1 is provided with a first groove 101. The structure and size of the first groove 101 are completely matched with the bottom shape and size of the first zipper head body 3. The first groove 101 works in conjunction with the limiting member 2 to prevent the first zipper head body 3 from disengaging from the first groove 101 and to prevent the first zipper head body 3 from sliding in the first groove 101.
[0052] Optionally, the area of the first groove 101 may be slightly larger than the bottom surface of the first slider body 3, so as to facilitate the installation of the first slider body 3 and thus be able to accommodate production errors.
[0053] In addition, the shape of the second zipper body 4 can be referenced in the appendix. Figure 4 Its bottom shape and size match the second groove 102. The outer periphery of the second groove 102 is provided with a limiting protrusion 104. The limiting protrusion 104, together with the zipper fixing accessory 5, can prevent the second zipper body 4 from rotating or sliding in the second groove 102.
[0054] Based on the above embodiment, the first zipper head body 3 and the second zipper head body 4 are arranged to abut against each other.
[0055] For details, please refer to the appendix. Figure 6The first slider body 3 and the second slider body 4 are respectively embedded in the first groove 101 and the second groove 102. The first slider body 3 is fixed by the limiting claw buckle 201, and the second slider body 4 is fixed by the slider fixing accessory 5, so that the right side of the first slider body 3 and the left side of the second slider body 4 abut against each other, thereby playing a mutual limiting role. In addition, as mentioned later, when both the first slider body 3 and the second slider body 4 are provided with through holes 401, their heads will not abut against each other.
[0056] Based on the above embodiments, the zipper pull fixing accessory 5 includes a large end 501, a hollow end 502 and a middle section 503. The large end 501 is connected to the hollow end 502 through the middle section 503. The size of the large end 501 is larger than the size of the through hole 103. The hollow end 502 is used to spread radially along the zipper pull fixing accessory 5 to achieve a snap-fit with the base 1.
[0057] Specifically, the structure of the zipper pull fixing accessory 5 can be found in the attached document. Figure 5 With appendix Figure 6 The upper end of the swivel head fixing accessory 5 is a large end 501, and the lower end is a hollow end 502. The size of the large end 501 is larger than the size of the through hole 103, and the cross-sectional size of the hollow end 502 is less than or equal to the size of the through hole 103, so that the hollow end 502 can pass through the through hole 103, while the large end 501 cannot pass through the through hole 103. After the hollow end 502 passes through the base 1, the side wall of the hollow end 502 is struck by the mold to make it fold outward. After folding outward, the area of the hollow end 502 is larger than the size of the through hole 103 on the base 1, thereby combining the second swivel head body 4 with the base 1. The striking deformation method is not limited and can be bending or expansion, etc.
[0058] Based on the above embodiments, the large end 501 is a round head or a plate-shaped head, the round head is connected to an intermediate segment 503, and the plate-shaped head is connected to one or two intermediate segments 503.
[0059] Specifically, the large end 501 of the zipper pull fixing accessory 5 in this application can also be a plate-shaped, ring-shaped, or other structure, the structure of which can be referred to the appendix. Figure 11 Appendix Figure 12 With appendix Figure 13 The design of the top cover of the fixing accessories has been adjusted, increasing the area and the fixing points that cooperate with the first zipper body 3 and the second zipper body 4.
[0060] Based on the above embodiment, the hollow end 502 is provided with several evenly distributed notches.
[0061] Specifically, several notches are provided on the hollow end 502. Before being struck, the hollow end 502 will not affect the passage of the through hole 103 and the through hole 401. After the hollow end 502 passes through the base 1, it can be deformed and spread out by striking or bending, thereby realizing the snap-fit between the pull head fixing accessory 5 and the base 1.
[0062] Based on the above embodiment, the surface of the base 1 facing away from the limiting member 2 is provided with a third groove 105, and the through hole 103 communicates with the third groove 105.
[0063] For details, please refer to the appendix. Figure 7 With appendix Figure 8 A third groove 105 is provided on the lower surface of the base 1. The through hole 103 is connected to the third groove 105. The third groove 105 should be larger than the through hole 103 so that the hollow end 502 enters the third groove 105 after passing through the through hole 103. The snap-fit part of the hollow end 502 after deformation can be stored in the third groove 105 without increasing the structural volume.
[0064] Based on the above embodiment, the base 1 is also provided with a rope hole 106.
[0065] Specifically, the base 1 is also provided with a rope hole 106, which can be used to thread a rope to connect the base 1 to the rope and reduce the weight of the base 1.
[0066] Furthermore, it should be noted that this application also provides a second type of double-pull head assembly, the structure of which can be referred to in the appendix. Figure 9 With appendix Figure 10 The difference from this application is that the first slider body 3 and the second slider body 4 have the same structure. The first groove 101 and the second groove 102 on the base 1 have the same shape and size, but are symmetrically arranged. The first slider body 3 and the second slider body 4 are connected by two fixing rods 601 on the upper cover plate 6. The upper cover plate 6 is also provided with a pull tab mounting jaw 602, which can be connected to the pull tab. In this solution, the slider heads are two identical slider heads placed opposite each other. The slider head fixing accessory 5, that is, the upper cover plate 6, is also extended to cover and add a pull tab mounting jaw 602 for connecting the pull tab. The number of the combination bases of the fixing rods 601 is also changed to two.
[0067] In addition to the aforementioned double-zipper assembly, this utility model also provides a zipper that includes the double-zipper assembly disclosed in the above embodiments. For the structure of the other parts of the zipper, please refer to the prior art, which will not be described in detail here.
[0068] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
