Description

Technical Field

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

[0002] Invisible zippers are a common product in everyday life, often used in conjunction with invisible sliders to achieve a more invisible effect. These sliders typically consist of a slider body and a pull tab. The slider body has a mounting portion with a mounting hole, and the pull tab has a connecting portion that rotatably fits within the mounting hole. Due to the small size and simple structure of the slider body, it's often impossible to incorporate complex fixing structures on the mounting portion to secure the pull tab. This results in the pull tab swaying with movement during use.

[0003] In order to solve this problem, the existing technology increases the friction between the mounting part and the connecting part by reasonably setting the size between the two, thereby achieving the fixation of the pull tab. That is, the mounting part is used to press the connecting part, thereby increasing the resistance encountered by the pull tab during the entire rotation process, so that the pull tab can be fixed at any position when not subject to external force.

[0004] While this method solves the problem of the pull tab shaking, it can be inconvenient to use due to the large resistance it encounters, making it difficult to lift the pull tab. Furthermore, due to friction between the slider's mounting and the tab's connection, the slider body is often made of a single piece of metal. This requires the entire pull tab, or at least the tab's connection, to be made of resin to prevent wear. Using other metal materials like zinc alloy can lead to excessive wear and tear, resulting in the pull tab becoming unable to rotate properly. Summary of the Invention

[0005] The utility model provides a zipper invisible slider, the main purpose of which is to solve the problems existing in the prior art.

[0029] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this embodiment provides a zipper invisible slider, including a slider body 1 and a pull tab 2, the slider body 1 has a mounting portion 11 with a mounting hole 12, and the pull tab 2 has a connecting portion 21 and a holding portion 22. The pull tab 2 is rotatably arranged in the mounting hole 12 through the connecting portion 21, so that the pull tab 2 can be flipped. The mounting portion 11 is provided with at least one boss 13, the connecting portion 21 and the boss 13 abut against each other, and the connecting portion 21 or the boss 13 has the ability to deform. Since there is friction between the mutually abutting connecting portion 21 and the boss 13, the position of the pull tab 2 can be fixed to prevent shaking; and since the connecting portion 21 or the boss 13 has the ability to deform, there will be no mutual wear between the two, and the friction will not be too large. The pull tab 2 can be driven to overcome the friction by a little force through the holding portion 22, thereby easily flipping.

[0032] like Figures 1 to 4As shown, specifically, the mounting portion 11 on the slider body 1 includes a support platform 111 and a needle tooth 112. The two needle teeth 112 are relatively arranged on both sides of the support platform 111 in the length direction and are riveted to form a mounting hole 12. The connecting portion 21 of the pull tab 2 includes a rotating shaft 211 and clamping arms 212 arranged at both ends of the rotating shaft 211. The holding portion 22 is connected to the ends of the two clamping arms 212. As a result, the pull tab 2 can be rotated in the mounting hole 12 by the rotating shaft 211 to achieve flipping. It should be noted that in actual applications, the friction between the mounting hole 12 and the rotating shaft 211 can be appropriately increased by reasonably setting the size between the two, thereby further ensuring that the pull tab 2 can be fixed in any position when not subject to external force.

[0033] like Figures 1 to 4 As shown, in this embodiment, there are two bosses 13, and the two bosses 13 are located on both sides of the mounting hole 12 on the support platform 111 in the width direction, thereby providing stable support for the connecting portion 21. The table top of the boss 13 is provided with an arcuate groove 131, and the two sides of the connecting portion 21 in the width direction are provided with arcuate surfaces that match the arcuate groove 131. In this embodiment, the rotating shaft 211 is designed as a cylindrical shaft, so the arcuate surface is the outer surface of the rotating shaft 211. The use of arcuate surface contact can make the contact between the boss 13 and the connecting portion 21 more uniform and reduce the wear between the two, so that the pull tab 2 can be turned more smoothly under the action of external force.

[0034] like Figures 1 to 4 As shown, as a preferred embodiment, the boss 13 is made of a non-deformable metal material, while the connecting portion 21 is made of a deformable resin material. Although the boss 13 and connecting portion 21 made of different materials abut and rub against each other, they do not wear each other out, effectively extending the life of the invisible slider. To simplify the production process, in this embodiment, the slider body 1 is made of a single piece of metal, while the pull tab 2 is made of a single piece of resin.

[0035] Example 2:

[0036] like Figures 5 to 8 As shown, unlike the first embodiment, this embodiment has only one boss 13, and the boss 13 is located within the mounting hole 12. Specifically, the boss 13 is located between the two pin teeth 112 on the support platform 111. The boss 13 is made of a deformable resin material, while the connecting portion 21 is made of a non-deformable metal material such as zinc alloy. This overcomes the drawback of the prior art that the connecting portion 21 of the pull tab 2 can only be made of resin, making the design of the invisible slider more flexible and more widely applicable.

[0037] like Figures 5 to 8As shown, more specifically, in this embodiment, the boss 13 is made by glue dripping. In order to increase the adhesion between the boss 13 and the mounting portion 11, a recess 113 is provided on the supporting platform 111, and the bottom of the boss 13 is inserted into the recess 113. The shape of the recess 113 can be flexibly designed according to actual conditions and is not limited here.

[0038] like Figures 5 to 8 As shown, in addition, in order to further improve the fit and structural stability between the boss 13 and the mounting portion 11, this embodiment also provides blocking platforms 14 on both sides of the mounting hole 12 in the width direction. The glue drips into the space between the two blocking platforms 14 without overflowing or moving. In other embodiments, the design of the recess 113 can also be eliminated, and the two blocking platforms 14 can directly form a fitting groove for mounting the boss 13. The blocking platform 14 can be made integrally with the slider body 1 using a metal material, but it should be noted that the height of the blocking platform 14 should be slightly lower than the height of the boss 13, so as to ensure that the connecting portion 21 of the pull tab 2 always abuts against the boss 13, avoiding wear between the connecting portion 21 and the blocking platform 14 and affecting the service life.

[0039] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
