Description

Technical Field

[0001] The utility model relates to the technical field of clothing zipper structures, and more particularly to a double-sided slider. Background Art

[0002] Zippers are a type of accessory used in clothing. Zippers are essentially composed of a slider, tape, chain teeth, and a square latch. The slider not only affects the zipper's functionality, but also its appearance and ease of use. Therefore, its structural design is crucial. There are many common types of sliders, including standard sliders, rail-type sliders, locomotive-type sliders, and spring-type sliders.

[0003] Different application scenarios have different requirements for the meshing parts used in zippers. When used in applications such as close-fitting clothing and thin skin clothing, the meshing parts need to be as compact as possible and provide a good user experience. At the same time, some applications require the meshing parts to be able to be opened and closed on both sides and do not require a self-locking function. Existing matching parts all use elephant trunk-style double-sided meshing parts without a self-locking function. The surface of the elephant trunk meshing parts has a nose bridge, and the protruding nose bridge makes the overall thickness of the meshing parts thicker, which cannot meet the requirements of current application scenarios for thinness and lightness. In addition, the elephant trunk pressing on the skin can cause discomfort.

[0004] Therefore, some improvements have been made to the nose-type pull head. By using a drawstring on the engagement part to reduce the thickness of the engagement part, the demand for lightness and thinness in current application scenarios has been met. However, there is still the problem of the rope head on the back of the chain engagement part squeezing and piercing the skin, causing discomfort.

[0005] In summary, how to avoid the rope end from squeezing or piercing the skin while ensuring the rope is light and thin is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0038] The present application provides a double-sided slider, comprising: a top plate 1, a bottom plate 3, a connecting plate 4 and a guide assembly 6;

[0039] Wherein, the surface of the top plate 1 is provided with a top plate through hole 2;

[0040] The bottom plate 3 is a plate-like structure;

[0041] The connecting plate 4 is provided between the heads of the top plate 1 and the bottom plate 3 to achieve a fixed connection between the top plate 1 and the bottom plate 3. The top end of the connecting plate 4 is provided with a connecting plate through hole 5 so that the top plate through hole 2 is connected to the connecting plate through hole 5.

[0042] The two ends of the guide component 6 pass through the top plate through hole 2 and the connecting plate through hole 5 respectively. A limiting component is provided on at least one of the guide component 6, the top plate through hole 2 and the connecting plate through hole 5. The limiting component is used to prevent the guide component 6 from falling off from the top plate through hole 2 or the connecting plate through hole 5.

[0043] For details, please refer to the attached Figure 1 , Attachment Figure 2 With attached Figure 7The top plate 1 and the bottom plate 3 are set correspondingly. For the inside and outside of the clothes, the top plate 1 is set toward the outside of the clothes, and the bottom plate 3 is set toward the inside of the clothes. The top plate 1 and the bottom plate 3 have the same outline. The two are fixedly connected by a connecting plate 4. Please refer to the attached Figure 1 The surface of the top plate 1 is provided with a top plate through hole 2, and the upper top surface of the connecting plate 4 is provided with a connecting plate through hole 5. The top plate through hole 2 is connected to the connecting plate through hole 5 to form a channel, and a guide component 6 is provided in the channel. Generally speaking, the guide component 6 is a drawstring, or a soft plastic or injection molded part, or a nylon belt, etc. This application and subsequent drawings only discuss the drawstring as an example. The drawstring has a certain length, and the two ends of the drawstring can extend out of the top plate through hole 2 and the connecting plate through hole 5 respectively. Both ends of the drawstring are fixed with limiting components, and the two limiting components can prevent the drawstring from escaping from the channel, and the drawstring can move in the channel. The zipper can be closed or opened by pulling the drawstring. For the slider as a whole, the connecting plate through hole 5 is provided at the top of the connecting plate 4. Compared with the prior art, it can prevent the guide component from squeezing and puncturing the skin under the premise of keeping the slider light and thin.

[0044] On the basis of the above embodiment, the limiting assembly includes two limiting blocks 7 , and a limiting block 7 is provided at each end of the guide assembly 6 . The size of the limiting block 7 is larger than the top plate through hole 2 and the connecting plate through hole 5 .

[0045] For details, please refer to the attached Figure 6 The two limit blocks 7 can be of the same structure or different structures, but the size of the limit block 7 corresponding to the top plate through hole 2 should be larger than the size of the top plate through hole 2, and the size of the limit block 7 corresponding to the connecting plate through hole 5 should be larger than the size of the connecting plate through hole 5 to prevent the pull rope from detaching from the top plate through hole 2 or the connecting plate through hole 5.

[0046] On the basis of the above embodiment, the top plate through hole 2 is a trumpet-shaped opening whose diameter gradually increases from the inside to the outside, the limit block 7 on the guide assembly 6 provided on one side of the top plate 1 is a truncated cone structure, the connecting plate through hole 5 is a cylindrical opening, and the limit block 7 of the guide assembly 6 provided on one side of the connecting plate 4 includes a fixedly connected cylindrical block and a strip block, the outer diameter of the cylindrical block is the same as the inner diameter of the cylindrical opening, and the length of the strip block is greater than the inner diameter of the cylindrical opening.

[0047] For details, please refer to the attached Figure 4 This application provides two double-sided sliders. The top plate through hole 2 and the connecting plate through hole 5 of the first double-sided slider can be openings of different structures. Please refer to the attached Figure 1The inner side dimension of the top plate through hole 2 is smaller than the dimension of its outer port. The present application provides three types of pull ropes. The limit block 7 corresponding to the top plate through hole 2 on the first pull rope is a truncated cone-shaped structure. The smaller end of the limit block 7 is set toward the top plate through hole 2, and the connecting plate through hole 5 at the head of the connecting plate 4 is a cylindrical through hole. The limit block 7 corresponding to the connecting plate through hole 5 on the first pull rope is composed of a cylindrical block and a strip block. The diameter of the cylindrical block is the same as the inner diameter of the connecting plate through hole 5, so that the cylindrical block can just be inserted into the connecting plate through hole 5, and the length of the strip block is greater than the inner diameter of the connecting plate through hole 5 to prevent the pull rope from falling off from the top plate through hole 2.

[0048] Optionally, the length of the strip block should not be too long, and its length can correspond to the length of the connecting plate 4 to improve the aesthetics of the structure.

[0049] On the basis of the above embodiment, the top plate through hole 2 and the connecting plate through hole 5 are both trumpet-shaped openings with diameters gradually increasing from the inside to the outside, and the two limit blocks 7 at both ends of the guide assembly 6 are both truncated cone structures.

[0050] For details, please refer to the attached Figure 5 The top plate through hole 2 and the connecting plate through hole 5 of the second double-sided slider can be of similar structure, that is, both are trumpet-shaped openings. The two limit blocks 7 at both ends of the second pull rope are both truncated cone-shaped structures. This type of pull rope is not reflected in the attached drawings. The smaller ends of the two truncated cone-shaped structures are both facing the through holes, and it is necessary to ensure that the base diameter of the truncated cone-shaped structure should be larger than the diameter of the smallest position in the top plate through hole 2 and the connecting plate through hole 5. This can not only prevent the pull rope from falling off the channel, but also partially hide the limit block 7 in the channel, or completely hide it in the channel, simplifying the structure and improving the structural aesthetics.

[0051] In some embodiments, the limiting assembly is provided at two ends of the guide assembly 6 , and the limiting assembly is used to fixedly connect the two ends of the guide assembly 6 to form an annular structure.

[0052] For details, please refer to the attached Figure 8 The limiting components at the two ends of the third type of pull rope are detachably arranged, and the two ends of the pull rope can be connected by the two limiting components to make the pull rope form a ring structure to ensure that the pull rope will not fall off from the channel.

[0053] Optionally, only one limit assembly may be provided, and the two ends of the pull rope are fixedly connected by one limit assembly, that is, as shown in the attached Figure 9 As shown in the figure, the structure is simplified and the stability is maintained.

[0054] On the basis of the above embodiment, the width dimensions from the head to the middle of the top plate 1 and the bottom plate 3 gradually increase, and the width dimensions from the middle to the tail of the top plate 1 and the bottom plate 3 gradually decrease, and chain closing protrusions 8 are provided on both sides of the top plate 1 and both sides of the bottom plate 3, and the chain closing protrusions 8 are used to realize the chain closing.

[0055] Specifically, for the top plate 1 and the bottom plate 3, both are structures that are wide in the middle and narrow at both ends. The tails of the top plate 1 and the bottom plate 3 are both provided with chain closing protrusions 8. As for the chain closing protrusions 8, the two chain closing protrusions 8 on the top plate 1 extend toward the bottom plate 3, and the two chain closing protrusions 8 on the bottom plate 3 extend toward the top plate 1. There is a small gap between the corresponding chain closing protrusions 8 on the top plate 1 and the bottom plate 3. The gap is only for the zipper tape part to pass through. For the slider, the chain closing process can be realized when the slider moves toward the direction of its head, and the reverse movement can realize the zipper unchaining process.

[0056] On the basis of the above embodiment, the connecting plate 4 is arranged on the central axis of the top plate 1 and the bottom plate 3 .

[0057] Specifically, for the top plate 1, the bottom plate 3 and the connecting plate 4, the connecting parts of the connecting plate 4 and the top plate 1 and the bottom plate 3 are respectively arranged parallel to the central axis of the top plate 1 and the bottom plate 3 to ensure that the space between the top plate 1 and the bottom plate 3 on both sides of the connecting plate 4 is symmetrical, so as to ensure that the slider can slide smoothly.

[0058] On the basis of the above embodiment, the width of the connecting plate 4 gradually decreases from its middle to its tail.

[0059] For details, please refer to the attached Figure 2 The thickness of the connecting plate 4 gradually decreases from the middle to the tail, that is, when the slider moves toward its tail, the tail of the connecting plate 4 can be directly inserted between the two chains of the zipper to achieve smooth chain opening.

[0060] On the basis of the above embodiment, chamfers are provided at the ends of the top plate through hole 2 and the connection plate through hole 5 .

[0061] Specifically, chamfers are set at the ends of the top plate through hole 2 and the connecting plate through hole 5 so that the limit block 7 can be inserted into the top plate through hole 2 or the connecting plate through hole 5 more smoothly, avoiding jamming during pulling the pull rope and improving the smoothness of pulling the pull head.

[0062] On the basis of the above embodiment, a top guide assembly protection layer 9 is provided on the top plate 1 .

[0063] Specifically, a top guide component protective layer 9 is provided on the surface of the top plate 1. The roughness of the protective layer is relatively low, which can reduce the friction between the pull rope and the pull head. Since the pull head is suitable for clothing, it needs to be cleaned frequently and is also susceptible to wind and sun. Reducing the friction of the pull rope during daily pulling can improve the service life of the pull rope to a certain extent.

[0064] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0065] The above describes in detail the double-sided slider provided by the present invention.
