Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of zippers, and particularly relates to a zipper slider and a zipper. Background Art
[0002] A zipper usually includes two parts: a zipper tape and a slider. The zipper tape includes two cloth tapes and a row of zipper teeth arranged along the length direction of each cloth tape. The slider includes a slider body, a slider base and a pull tab. The slider base is arranged below the slider body and cooperates with the zipper teeth to realize the opening and closing of the zipper. The pull tab is connected to the slider body to pull the slider to move in the length direction of the zipper tape. The slider body can also be called a slider retainer, which is used to prevent the slider base and the pull tab from being worn during use and to extend the service life of the pull cord and the pull tab.
[0003] With the widespread application of zipper products, not only in the field of traditional clothing, but also in non-traditional clothing such as luggage, automobiles, and household items. For many products, in order to maintain the consistency of appearance and pursue waterproof and wear-resistant performance, zippers and other auxiliary products are usually hidden inside the external fabric to achieve an "invisible" visual effect.
[0004] like Figure 1 As shown, in order to realize the hidden design, only the pull tab 01 and a small part of the slider body 02 are exposed on the outer surface of the product above the hidden fabric 03. In actual use, the pull tab 01 is used to pull and close the zipper, and the pull tab 01 will constantly rub and collide in the bite gap 04 of the slider body 02. If the zipper is stuck or jammed during use, the pull tab 01 may deform the slider body 02 under the condition of forced force, especially expand and deform outward at the bite gap 04, causing the pull tab 01 to fall off. In addition, the pull tab 01 will rub against the slider body 02 for a long time during use, especially the frequent friction at the bite gap 04, which will cause the pull tab 01 or the slider body 02 to wear more, causing the paint layer or the plating layer to fall off.
[0005] Therefore, how to overcome the above technical defects is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0044] The core of the utility model is to provide a zipper pull head and a zipper, which can effectively improve the torsion resistance of the pull head body and extend the service life of the zipper pull head.
[0045] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0046] Specifically, please refer to Figure 1-Figure 8 The utility model provides a zipper slider A, comprising a slider body 1, a slider base 2 and a pull tab 3.
[0047] A slider base 2 is provided below the slider body 1. The triangular structure on the slider base 2 is used to cooperate with the zipper teeth on the zipper tape B to realize the opening and closing of the zipper. The slider body 1 can cooperate with the pull tab 3 to realize the reciprocating movement of the zipper slider A relative to the zipper tape B.
[0048] The slider body 1 is provided with an engagement gap for connecting the pull tab 3 , that is, the slider body 1 is an annular structure, and the slider body 1 forms an opening at the engagement gap that can penetrate the outside and the inner circle of the annular structure.
[0049] Among them, one of the upper surface and the lower surface of the slider body 1 at the bite gap is provided with an engaging groove 101, and the other is provided with an engaging protrusion 102 for matching with the engaging groove 101.
[0050] It can be understood that, in one form, the upper surface of the slider body 1 at the bite gap is provided with an engaging groove 101, and the lower surface at the bite gap is provided with an engaging protrusion 102; in another form, the upper surface of the slider body 1 at the bite gap is provided with an engaging protrusion 102, and the lower surface at the bite gap is provided with an engaging groove 101.
[0051] The structure of the slider body 1 itself has a certain elasticity, especially when it is made of metal. When the pull tab 3 is aligned with the slider body 1, the slider body 1 is pressed to make the engaging protrusion 102 embed into the engaging groove 101, so that the engaging protrusion 102 and the engaging groove 101 are snap-fitted.
[0052] Specifically, a mounting groove is provided on the pull tab 3, and the pull tab 3 can pass through the engaging gap of the slider body 1 and be inserted into the mounting groove of the pull tab 3 through the engaging protrusion 102, so as to realize the connection between the pull tab 3 and the slider body 1, thereby restricting the pull tab 3 on the slider body 1.
[0053] The utility model provides a zipper slider A, which is provided with an interlocking groove 101 and an interlocking protrusion 102 structure on the upper surface and the lower surface of the slider body 1 at the interlocking gap, so that the connection of the slider body 1 at the interlocking gap is more stable through a snap-fitting manner. When the pull piece 3 collides or rubs at the interlocking gap of the slider body 1, the torsion resistance of the slider body 1 can be effectively improved, thereby extending the service life of the zipper slider A.
[0054] In addition, since the engaging protrusion 102 and the engaging groove 101 on the slider body 1 are engaged with each other by a snap-fitting manner, its lateral torsion resistance can be greatly improved. At the same time, it can also prevent the slider body 1 from being deviated from the centerline at the upper and lower surfaces of the engaging gap when the pull tab 3 is forcibly pulled for a long time, causing deformation.
[0055] In a specific embodiment, the slider body 1 is an annular structure, and the inner wall of the annular structure in contact with the pull tab 3 is an elliptical line shape. The elliptical line shape refers to the cross-sectional shape of the slider body 1 located on the inner side, such as Figure 6 As shown, the inner wall where the annular structure contacts the pull tab 3 is the contact point 103 between the slider body and the pull tab shown in the figure. In order to reduce the contact friction with the rotating part of the pull tab 3, the slider body 1 improves the traditional rounded rectangular line inner wall surface to an elliptical line. Of course, the contact position between the pull tab 3 and the inner wall of the slider body 1 can also be adaptively designed to be the elliptical line. The above arrangement can reduce the number of collisions with the rotating part of the pull tab 3 and better fit the inner arc curve.
[0056] In a specific embodiment, the bending curvature of the engaging protrusion 102 in the extending direction from far to near relative to the engaging groove 101 gradually increases. Of course, the bending curvature of the engaging protrusion 102 and even the part of the slider body 1 connected to the engaging protrusion 102 in the extending direction from far to near relative to the engaging groove 101 can also be designed to have a gradually increasing trend.
[0057] The slider body 1 near the engaging protrusion 102 is in an inward buckle structure, so that the pulling direction of the pull tab 3 at a preset position / a certain position coincides with the normal direction of the outer arc of the slider body 1 .
[0058] like Figure 7 As shown, by adjusting the curvature of the engaging protrusion 102 or even the slider body 1 at the connection point, the slider body 1 can be made to "buck inward", so that the pull tab 3 can move only within the curvature when being pulled.
[0059] It should be noted that such a configuration can, on the one hand, change the force direction of the zipper during use. The normal direction of the outer arc line of a traditional slider generally does not coincide with the pulling direction. After being adjusted to an "inward buckle" structure in this scheme, it can be achieved that during the pulling process, the pulling direction of the pull tab 3 coincides with the normal direction of the outer arc line of the slider body 1, thereby avoiding the risks of pulling jamming and deformation of the slider body 1 due to force decomposition; at the same time, it avoids the friction and wear of the pull tab 3 at the joint during the pulling process, thereby extending the service life of the coating or paint layer at the rotating part of the pull tab 3.
[0060] In a specific embodiment, the engaging protrusion 102 corresponds to the engaging groove 101 one by one, and the number can be one or multiple intermittently arranged. The design of multiple engaging protrusions 102 and engaging grooves 101 can further improve the stability and reliability of the connection.
[0061] In order to improve the structural strength, the slider body 1 and the engaging protrusion 102 are an integrated structure.
[0062] The setting of the interlocking protrusion 102 can raise the height of the slider body 1 (equivalent to the pull tab 3 holder), change the center of gravity, prevent the slider body 1 from deflecting and limit the lateral deflection of the slider body 1, and prevent the structure from deforming. In addition, the pull tab 3 of the slider can be completely extended outside the product, avoiding the problems of increased wear on the fabric and unsmooth opening and closing of the zipper.
[0063] In a specific embodiment, the pull head is a metal pull head, a resin pull head, a plastic pull head or a nylon pull head. Common pull head structures can be made of metal materials, resin materials, plastic materials or nylon materials, etc., and suitable materials can be selected according to actual needs.
[0064] In order to achieve the installation of the pull tab 3 on the slider body 1, the outer diameter of the installation groove of the pull tab 3 is at least larger than the outer diameter of the engaging protrusion 102. Of course, in order to improve the reliability of the connection, the outer diameter of the installation groove of the pull tab 3 also needs to be larger than the outer diameter of the slider body 1 so that the pull tab 3 can contact the inner wall of the slider body 1.
[0065] The shapes of the engaging protrusion 102 and the engaging groove 101 can be adaptively selected according to actual needs. Specifically, the engaging protrusion 102 with a rounded rectangular cross section can be used.
[0066] In addition, the utility model also provides a zipper, including: a zipper slider A and a zipper tape B as in the above specific embodiment, wherein the slider base 2 of the zipper slider A cooperates with the zipper teeth on the zipper tape B to realize the opening and closing of the zipper.
[0067] The slider base 2 in the zipper slider A is adapted to the zipper teeth of the zipper tape B. Specifically, the pull tab 3, the slider base 2 and the zipper tape B can be selected in different sizes and shapes according to actual needs.
[0068] The general outline of the slider body 1 in this solution can be consistent with the conventional slider body 1, and only the engaging protrusion 102 and the engaging groove 101 are provided at the occlusal gap, that is, the slider body 1 of the utility model can be fully adapted to the conventional zipper. Of course, the shape of the slider body 1 can also be slightly adjusted based on the conventional slider body 1.
[0069] Obviously, the zipper with the above-mentioned zipper slider A has the same beneficial effects, which will not be described in detail here.
