Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a slider and a zipper. Background Art

[0002] Zippers are common everyday items that connect or separate items using a continuous array of chain elements. They are widely used in clothing, bags, tents, and other areas. Zippers can be categorized by material, including nylon, resin, and metal. Nylon zippers are commonly used on clothing and luggage, while metal zippers are often used on jeans, jackets, and backpacks due to their durability.

[0003] A zipper typically includes two fabric tapes, each of which has a plurality of teeth on one side. The zipper also includes a slider for engaging and disengaging the teeth. The slider typically includes a base and a pull tab connected to the base. Sometimes, in order to reduce the weight of the slider, manufacturers use a rope instead of a pull tab to reduce the overall weight of the slider. For example, a fixed double-sided slider disclosed in the prior art maintains structural stability when the slider is not in use by designing an assembly method that combines the slider with a stopper. When in use, one stopper is allowed to separate and serve as a handle, while the other stopper is connected to the slider via a pull cord, thereby enhancing the slider's stability and ease of use. However, the slider structure is relatively complex, and when the stopper at one end of the rope is fixed to the rear end of the slider, when the user pulls the rope at the front end of the other side of the slider, the rear end and front end of the slider, as well as the upper and lower surfaces, have different force points, resulting in uneven force on the slider, which can cause the slider to jam when pulled. Therefore, how to provide a slider and a zipper with a simple structure, uniform force on the slider, and smooth sliding is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] The purpose of the utility model is to provide a slider and a zipper, which solves the technical problem that the existing slider structure is relatively complicated and the slider is unevenly stressed during use, resulting in jamming when the slider is pulled.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Please refer to Figures 1 to 7 The utility model provides a slider and a zipper, wherein a drawstring 20 passes through the mounting hole 11 of the pull body 10. Under the action of the drawstring 20, the fixing member 21 can enter the mounting hole 11 and be fixed to the pull body 10 through the mounting hole 11. By pulling the drawstring 20, the slider can be driven to slide. The structure is simple and easy to use.

[0031] Please refer to Figures 1 to 7 The pull head provided by the utility model includes a pull body 10 and a pull rope 20; the pull body 10 is provided with a mounting hole 11, the mounting hole 11 is located at the front end of the pull body 10, and the mounting hole 11 passes through the pull body 10; at least one end of the pull rope 20 is provided with a fixing part 21, the pull rope 20 passes through the mounting hole 11, and the fixing part 21 is fixed to the pull body 10 through the mounting hole 11 under the action of the pull rope 20, or detached from the mounting hole 11 and separated from the pull body 10.

[0032] When in use, the pull cord 20 passes through the mounting hole 11 of the pull body 10. When the pull cord 20 is pulled, the fixing member 21 enters the mounting hole 11 under the action of the pull cord 20 and is fixed to the pull body 10 through the mounting hole 11. The fixing member 21 remains fixed on the pull body 10, and pulling the pull cord 20 can drive the slider to slide. The structure is simple and easy to use. The fixing member 21 is fixed to the front end of the pull body 10 through the mounting hole 11. When the user pulls the pull cord 20 on the other side of the pull body 10, the force is applied to the front end of the pull body 10, and the force is evenly applied to the upper and lower surfaces of the pull body 10, ensuring smooth pulling and sliding.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4 The pull cord 20 is provided with fixing members 21 at both ends. When both ends of the pull cord 20 are provided with fixing members 21, after one fixing member 21 is fixed to the pull body 10 through the mounting hole 11, the fixing member 21 at the other end can be used to pull the pull cord 20 to cause the slider to slide. In other words, by switching the fixing member 21 fixed to the pull body 10, a double-sided pulling function can be achieved. When the user pulls the pull cord 20, the force is applied at the front end of the pull body 10, and the force is evenly applied to the upper and lower surfaces of the pull body 10, ensuring smooth pulling.

[0034] Please refer to Figure 5 and Figure 6 Alternatively, the fixing member 21 may be provided at only one end of the pull cord 20. When the fixing member 21 is provided at one end of the pull cord 20, after the fixing member 21 is secured to the pull body 10 through the mounting hole 11, the pull cord 20 can be pulled in one direction to cause the slider to slide. When the user pulls the pull cord 20, the force is applied uniformly at the front end of the pull body 10, and the force is evenly applied to the upper and lower surfaces of the pull body 10, thus ensuring smooth sliding.

[0035] For details, please refer to Figure 1 、 Figures 4 to 7In this embodiment, the fixing member 21 includes a head portion 211, a waist portion 212, and a clamping portion 213, which are sequentially arranged. The waist portion 212 is located between the head portion 211 and the clamping portion 213. When the pull cord 20 drives the fixing member 21 to be fixed to the pull body 10, the waist portion 212 enters the mounting hole 11, and the head portion 211 and the clamping portion 213 engage with the pull body 10. Specifically, the diameter of the waist portion 212 is slightly larger than the diameter of the mounting hole 11. A strong force is applied to force the waist portion 212 of the fixing member 21 into the mounting hole 11, and the waist portion 212 and the mounting hole 11 form an interference fit to achieve fixation. The waist portion 212 can also be made of a soft material. The waist portion 212 penetrates the mounting hole 11 through its own elasticity. The waist portion 212's own resilience will press against the inner wall of the mounting hole 11, generating friction, thereby securing the waist portion 212 to the mounting hole 11. The clamping portion 213 is made of a soft material. In its natural state, its diameter is larger than that of the mounting hole 11. Due to its soft material properties, the clamping portion 213 can be squeezed by the mounting hole 11 to reduce its diameter and pass through it. When the clamping portion 213 is no longer squeezed by the mounting hole 11, it returns to its natural state. The head portion 211 has a larger diameter than the mounting hole 11 and cannot pass through it. The clamping portion 213 and the head portion 211 engage the pull body 10 from the top and bottom, respectively, to restrict movement of the fixing member 21 along the axis of the mounting hole 11.

[0036] Please refer to Figure 1 、 Figure 3 and Figure 7 The pull body 10 includes a first wing plate 12 and a second wing plate 13. The first wing plate 12 and the second wing plate 13 are arranged in parallel and connected by a connecting post 14. The mounting hole 11 passes through the first wing plate 12, the connecting post 14, and the second wing plate 13. The first wing plate 12 and the second wing plate 13 mainly serve as limiters, so that the chain element 31 can move within the space between the first wing plate 12 and the second wing plate 13 without disengaging. The first wing plate 12 and the second wing plate 13 are generally arranged in parallel. Through this arrangement, the chain element 31 can slide smoothly within the space formed by the first wing plate 12 and the second wing plate 13. The function of the connecting column 14 is to connect or disconnect the chain. The connecting column 14 is an indispensable part of the slider structure and is generally a columnar structure. The connecting column 14 is arranged between the head of the first wing plate 12 and the head 211 of the second wing plate 13. The connecting column 14 is located on the same side of the first wing plate 12 and the second wing plate 13, that is, the connecting column 14 is located at the front end of the slider, and the connecting column 14 should be arranged at the center axis of the first wing plate 12 and the second wing plate 13. Through such an arrangement, it is ensured that the space on both sides of the first wing plate 12 and the second wing plate 13 on both sides of the connecting column 14 is symmetrical, so as to ensure that the slider can be pulled smoothly. The fixing member 21 is fixed to the front end of the slider through the mounting hole 11. When the user pulls the pull rope 20 on the other side of the slider, the force points are all at the front end of the slider, and the upper and lower surfaces of the slider are evenly stressed, so that the teeth engage and separate without jamming.

[0037] Please refer to Figures 1 to 3 A limiting groove 15 is provided on the side of the first wing plate 12 and the second wing plate 13 facing away from each other. The limiting groove 15 is located outside the mounting hole 11, and the head 211 of the fixing member 21 is used to engage with the limiting groove 15. When the pull rope 20 drives the fixing member 21 to be fixed to the pull body 10, the waist portion 212 enters the mounting hole 11, and the head 211 and the engaging portion 213 engage with the pull body 10. The head 211 of the fixing member 21 engages with the pull body 10 from one side through the limiting groove 15, and the engaging portion 213 of the fixing member 21 engages with the pull body 10 from the other side, limiting the movement of the fixing member 21 in the axial direction of the mounting hole 11.

[0038] A retaining groove 15 is provided on the side of the first wing 12 and the second wing 13 facing away from each other, that is, both the first wing 12 and the second wing 13 are provided with a retaining groove 15. It is understood that when a fixing member 21 is provided at each end of the pull cord 20, the two fixing members 21 can respectively cooperate with the two retaining grooves 15. After one fixing member 21 is secured to the pull body 10 through the mounting hole 11, the fixing member 21 at the other end can be used to pull the pull cord 20 and cause the pull head to slide. In other words, by switching the fixing member 21 secured to the pull body 10, a double-sided pulling function can be achieved. When a fixing member 21 is provided at one end of the pull cord 20, the fixing member 21 cooperates with one of the retaining grooves 15.

[0039] Please refer to Figure 7 The drawstring 20 passes through the clamping portion 213 and the waist portion 212 and extends into the head portion 211. This arrangement not only ensures the connection between the drawstring 20 and the fixing member 21, but also increases the connection strength between the fixing member 21 and the drawstring 20. Furthermore, the head portion 211, the waist portion 212, and the clamping portion 213 can be located on the same axis. The drawstring 20 is arranged within the fixing member 21 along this axis, and the end of the drawstring 20 is arranged within the fixing member 21. This allows the fixing member 21 to fully cover the end of the drawstring 20, thereby protecting the end of the drawstring and reducing wear. The fixing member 21 and the drawstring 20 can be connected by injection molding, in which case the fixing member 21 is made of injection molding material.

[0040] Please refer to Figure 1 、 Figures 4 to 7 The waist 212 of the fixing member 21 and the head 211 and the clamping portion 213 of the fixing member 21 are smoothly connected, and the connection between the mounting hole 11 and the limiting groove 15 is smoothly transitioned. When the fixing member 21 is fixed in the mounting hole 11, the head 211 and the clamping portion 213 fit tightly with the pull body 10, increasing the sealing and connection reliability between the fixing member 21 and the surface of the pull body 10.

[0041] In addition, the smooth connection method has the following advantages: 1. It reduces stress concentration and increases the strength and durability of the connection; 2. It can reduce wear and collision during use, installation, disassembly and transportation, and reduce maintenance and replacement costs; 3. It can make the appearance smoother and more comfortable, which can improve the aesthetics.

[0042] Please refer to Figure 1 、 Figures 4 to 7 The side of the head 211 away from the waist 212 is an arc-shaped surface, which protrudes outward and is smoothly connected to the side of the head 211. This arrangement reduces the discomfort caused by the head 211 squeezing the skin surface when the head 211 of the fixing member 21 contacts the skin.

[0043] Please refer to Figures 1 to 3 、 Figure 7 The surfaces of the first wing 12 and the second wing 13 facing away from each other are flat. The first wing 12 and the second wing 13 remain flat. After the fixing member 21 is installed on the pull body 10 through the mounting hole 11, the head 211 of the fixing member 21 slightly protrudes from the surface of the pull body 10. The material of the head 211 can be either soft or hard. Preferably, the head 211 is made of a soft material so that there is no pressure when it comes into direct or indirect contact with the skin, thereby avoiding scratches.

[0044] The pull head provided by the present invention and the fixing member 21 can be integrally formed by silicone die casting or plastic injection molding. The pull rope 20 and the fixing member 21 are connected by die casting or injection molding to improve the connection strength.

[0045] Please refer to Figure 1 In addition to the sliders disclosed in the above embodiments, the present invention also provides a zipper including the sliders. The zipper further includes two zipper tapes 30, with two rows of fastener elements 31 arranged alternately. The slider clamps the fastener elements 31 on both sides. By pulling the slider and sliding it along the fastener elements 31, the fastener elements 31 on both sides can be engaged or disengaged.

[0046] The pull head provided by the utility model has a pull cord 20 passing through the mounting hole 11 of the pull body 10. Under the action of the pull cord 20, the fixing member 21 enters the mounting hole 11 and is fixed to the pull body 10 through the mounting hole 11. By pulling the pull cord 20, the pull head can be driven to slide. The structure is simple and easy to use. The fixing member 21 is fixed to the front end of the pull head through the mounting hole 11. When the user pulls the pull cord 20 on the other side of the pull head, the force points are all at the front end of the pull head. The upper and lower surfaces of the pull head are evenly stressed, so that the teeth engage and separate without jamming, ensuring smooth pulling. When fixing members 21 are provided at both ends of the pull cord 20, after one of the fixing members 21 is fixed to the pull body 10 through the mounting hole 11, the pull cord 20 can be pulled through the fixing member 21 at the other end to drive the pull head to slide. That is, by switching the fixing member 21 fixed to the pull body 10, it can have a double-sided pulling function. Since the zipper includes a pull head, the same technical effect can be produced.

[0047] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0048] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
