As shown in FIG. 1-7, in a specific embodiment of the present invention, a zipper head includes: a slider body 1 for opening and closing a fastener element; a pull tab 2 for pulling the slider body 1 An accommodating portion 3 provided on the slider body 1 and connecting the pull tab 2 to an upper surface of the slider body 1 through an accommodating space 4 formed by the accommodating portion 3; an elastic member 5 provided on At the slider body 1 corresponding to the accommodating space 4 formed by the accommodating portion 3, the elastic member 5 is always in a compressed state, and a radial elastic force is applied to the pull tab 2 to limit the pull tab 2 Flip. The restrictive flipping effect of the elastic member 5 on the pull tab 2 should first ensure that the pull tab 2 can be flipped in the accommodation space 4. When the pull tab 2 is flipped at any position in the accommodation space 4, the elastic member 5 can be used with the pull tab 2 Contact, because the elastic member 5 is always in a compressed state, the elastic member 5 will exert a radial direction elastic force on the pull tab 2. During the turning of the pull tab 2 due to the influence of the radial elastic force, the flip will be damped to a certain extent and Obstacles make the pull tab 2 have a certain damping feeling when it is flipped, and due to the elasticity of the elastic member 5, the pull tab 2 can be flipped under the effect of external force, and when there is no external force to flip the pull tab 2, With the influence of the radial elastic force provided by the compressed state of the elastic member 5, the pull-tab 2 will be fixed in the accommodation space 4 without shaking or turning randomly, thereby limiting the free-turning of the pull-tab 2 under no force And compared with the original slider composed of multiple parts, the number of parts is reduced, the slider is simpler, and it is more convenient and quick to assemble. The elastic member 5 may be disposed on the upper surface of the slider body 1 corresponding to the accommodating space 4. As shown in FIG. 5, a radial elastic force is generated on the pull tab 2 through contact with the pull tab 2, and the flip of the pull tab 2 is generated.

By generating a radial elastic force on the pull-tab 2, the flip-tab 2 can also be flipped over A damping and blocking effect can also limit the free flip of the pull tab 2 under no force, and at the same time make the pull tab 2 not shake when it is not flipped. The elastic member 5 may be an airbag, an elastic rubber, a thermoplastic elastomer, or a spring. There are no specific restrictions on the performance parameters such as the number, length, and width of the elastic member 5, as long as the same technical effect can be achieved, the accommodation space 4 It can be half-open or closed. The accommodating portion 3 can be separate or integrated. As shown in FIGS. 5, 6 and 7, as long as the pull-tab 2 can pass through the accommodating space 4 formed by the accommodating portion 3. Connected to the upper surface of the slider body 1 so that the slider 2 can contact the slider body 1 and complete the pulling work. The accommodation space 4 should first ensure that the slider 2 does not fall out of the accommodation space 4 and can better The fixed pull tab 2 makes the whole slider more stable, and can ensure that the pull tab 2 can always be flipped in the accommodation space 4. The design of the accommodation space 4 is the existing technology well known to those skilled in the art, and is no longer here To repeat.

In another specific embodiment of the present invention, the pull-tab 2 includes a connecting shaft 6, and the connecting shaft 6 is disposed in an accommodating space 4 formed by the accommodating portion 3, and the elastic member 5 opposes the connecting shaft. 6 applies a radial elastic force to limit the rotation of the connecting shaft 6. It should be noted here that the cross-sectional shape of the connecting shaft 6 is not specifically limited, and may be circular or square. The specific structure and number of the connecting shafts 6 are also not limited. When the connecting shaft 6 is one, and When it is a whole, one elastic member 5 can be provided correspondingly.

When the connecting shaft 6 is a two-piece structure that is disconnected It is possible to set corresponding two elastic bodies or multiple elastic bodies corresponding to the two sections of structures, as long as the same technical effect can be achieved, and details are not described here. The elastic member 5 is optimally in contact with the center of the connecting shaft 6, so that the radial elastic force applied to the connecting shaft 6 can be consistent with the center or the center of gravity of the connecting shaft 6 to better act on the connecting shaft 6, of course, also It may not act on the center of the connecting shaft 6 as long as the same technical effect can be achieved.

In another specific embodiment of the present invention, it further includes an accommodation groove 7, the elastic member 5 is disposed in the accommodation groove 7, and the accommodation groove 7 is disposed in an accommodation space 4 formed with the accommodation portion 3. Corresponding to the slider body 1. The depth of the accommodating groove 7 can be designed according to the corresponding needs, as long as it does not penetrate the slider body 1, and the width and depth of the accommodating groove 7 can also be adaptively adjusted according to the shape of the slider body 1. It is only necessary to achieve the same technical effect. Preferably, the width of the receiving groove 7 is consistent with the width of the receiving space 4. On the one hand, the placement of the elastic member 5 in the receiving groove 7 is more stable, and on the other hand, the slider body can be reduced. The processing of 1 ensures that the slider body 1 has a certain strength, and the number of the elastic members 5 is not specifically limited. It can be one or more. It can be adaptively adjusted according to the size of the receiving groove 7 as long as it can reach The same technical effect is enough, and the number can be adjusted accordingly according to the actual design needs, which are easily conceived by those skilled in the art. It should be particularly noted here that the receiving groove 7 is not a through hole, that is, since it is a groove It must not be a hole, so the accommodating groove 7 only has an opening on the surface of the slider body 1 and must not penetrate the slider body 1, which is well known to those skilled in the art. There are technical terms, we will not repeat them here. Specifically, the elastic member 5 is a spring. When the elastic member 5 is a spring, the initial length of the spring is greater than the depth of the receiving groove 7. When the pull tab 2 is disposed in the receiving space 4, it contacts the spring and generates a certain pressure on the spring. , Then the spring will naturally generate a radial elastic force on the slider. When the pull-tab 2 is turned by external force, the pull-tab 2 will be subject to a certain limit of flipping under the effect of the radial elastic force, resulting in a certain flipping resistance. When the external force is turned over, the radial elastic force of the spring in cooperation with the receiving portion 3 will prevent the pull-over piece 2 from turning freely without action.
