[0005] Optionally, the first protrusion is an annular protrusion extending along the periphery of the second wing.

[0006] Optionally, if the height of the annular protrusion is H and the thickness of the second wing is D, the following relationship is satisfied: H≥(H+D) / 10.

[0007] Optionally, a second protrusion is arranged on the second wing facing away from the first wing, and the second protrusion is located inside the annular protrusion.

[0008] Optionally, a height of the second protrusion is greater than a height of the annular protrusion.

[0009] Optionally, a third protrusion is provided on the surface of the first wing facing away from the second wing.

[0010] Optionally, a surface of the first wing facing away from the second wing and corresponding to a middle portion of the cap is recessed toward the second wing to form a groove, and two ends of the groove extend out of opposite sides of the cap respectively.

[0011] Optionally, a first slope is provided at an edge of the first wing, and the first slope extends obliquely outwardly from a surface of the first wing facing away from the second wing and toward the second wing and is connected to a side surface of the first wing.

[0012] Optionally, a second slope is provided at an edge of the second wing, and the second slope extends obliquely outwardly from a surface of the second wing facing away from the second wing and toward the first wing and is connected to a side surface of the second wing.

[0013] The above one or more technical solutions in the slider provided by the present invention have at least one of the following technical effects: during the electroplating and painting process, since a cap is provided on the surface of the first wing facing the outer side of the slider, when other sliders contact with the first wing, they are blocked by the cap, and the surfaces of other sliders cannot be fitted with the surface of the first wing in a large area and stick together; at the same time, a first protrusion is also provided on the surface of the second wing facing the outer side of the slider, so when other sliders contact with the second wing, they are blocked by the first protrusion, and the surfaces of other sliders cannot be fitted with the surface of the second wing in a large area and stick together, thereby solving the problem of slider sticking, reducing the rework rate of the slider, improving the success rate of electroplating or painting, and greatly reducing the production cost.

[0014] The technical solution adopted by the present invention is: a zipper, comprising the above-mentioned slider.

[0015] The zipper of the present invention adopts the above-mentioned slider. During the electroplating or painting process of the slider, the slider is blocked by the first protrusion and the cap, so that the other slider surfaces cannot be closely attached to the surface of the second wing over a large area and stick together. This solves the problem of slider sticking, reduces the rework rate of the slider, improves the success rate of electroplating or painting, and greatly reduces the production cost.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 5 As shown, in one embodiment of the present invention, a slider is provided, which is mainly used in conjunction with a chain belt having chain teeth to form a zipper; the slider includes a first wing 10, a second wing 20, a guide post 30 and a cap 40, the first wing 10 and the second wing 20 are arranged relatively spaced apart, and the two ends of the guide post 30 are respectively connected to the first wing 10 and the second wing 20, wherein the two chain belts respectively penetrate into or out of between the first wing 10 and the second wing 20 on both sides of the guide post 30, so that the chain teeth on the two chain belts are engaged or disengaged with each other, thereby realizing the opening and closing of the zipper; further, the cap 40 is installed on the surface of the first wing 10 facing away from the second wing 20, wherein the cap 40 is used as a pull tab for people to hold, so as to facilitate the slider to move back and forth on the two chain belts; further, the surface of the second wing 20 facing away from the first wing 10 is provided with a first protrusion 21.

[0032] Specifically, in the process of electroplating and baking finish of the slider of the embodiment of the present invention, since the cap 40 is provided on the surface of the first wing 10 facing the outer side of the slider, when other sliders contact with the first wing 10, they are blocked by the cap, and the surfaces of other sliders cannot be closely fitted with the surface of the first wing 10 over a large area and stick together; at the same time, the surface of the second wing 20 facing the outer side of the slider is also provided with a first protrusion 21, so when other sliders contact with the second wing 20, they are blocked by the first protrusion 21, and the surfaces of other sliders cannot be closely fitted with the surface of the second wing 20 over a large area and stick together, thereby solving the problem of slider sticking, reducing the rework rate of the slider, improving the success rate of electroplating or baking finish, and greatly reducing the production cost.

[0033] In this embodiment, the first wing 10 and the second wing 20 are arranged in parallel and spaced apart, and the guide column 30 is vertically connected between the first wing 10 and the second wing 20, and the first wing 10, the second wing 20 and the guide column 30 are integrally formed. This manufacturing method is simple, and the manufactured slider has good structural strength, which greatly increases the service life of the slider.

[0034] In another embodiment of the present invention, refer to Figure 3As shown, the first protrusion 21 of the slider is an annular protrusion extending along the periphery of the second wing 20 .

[0035] Specifically, the annular protrusion surrounds the exposed surface of the second wing 20, so that other sliders can be blocked from adhering to the surface of the second wing 20, thereby greatly improving the anti-adhesion effect.

[0036] Furthermore, under the premise of ensuring the normal use of the slider, the annular protrusion can also be formed by the middle of the surface of the second wing 20 being recessed toward the first wing 10, which can greatly reduce the material consumption of the entire slider and achieve the purpose of lightweight and material reduction.

[0037] In another embodiment of the present invention, refer to Figure 2 As shown, if the height of the annular protrusion of the slider is H and the thickness of the second wing 20 is D, the following relationship is satisfied: H≥(H+D) / 10.

[0038] Specifically, the height H of the annular protrusion protruding from the surface of the second wing 20 is appropriate, which can play a good blocking role and anti-sticking effect. If the height of the annular protrusion is set too small, it cannot effectively play a blocking role.

[0039] Optionally, the height of the annular protrusion is less than the thickness of the second wing 20, so as to avoid the annular protrusion being too high and causing the slider to be too large, and causing the electrolyte or paint solution to accumulate in the annular protrusion.

[0040] In another embodiment of the present invention, refer to Figure 3 As shown, the second wing 20 of the slider is provided with a second protrusion 22 facing away from the first wing 10, and the second protrusion 22 is located inside the annular protrusion.

[0041] Specifically, a second protrusion 22 is provided on the surface of the second wing 20 located inside the annular protrusion, so that when the slider extends into the annular protrusion and contacts the surface of the second wing 20, the second protrusion 22 can play a blocking role to prevent the sliders from sticking together over a large area, thereby improving the anti-sticking effect.

[0042] In another embodiment of the present invention, refer to Figure 3 and Figure 4 As shown, the height of the second protrusion 22 of the slider is greater than the height H of the annular protrusion.

[0043] Specifically, the height of the second protrusion 22 is greater than the height of the annular protrusion, so that the second protrusion 22 protrudes out of the annular protrusion. In this way, during the electroplating or painting process, the second protrusion 22 can push away other sliders to prevent other sliders from contacting the second wing 20, greatly reducing the adhesion rate between the sliders.

[0044] In another embodiment of the present invention, refer to Figure 1 As shown, a third protrusion 11 is provided on the surface of the first wing 10 of the slider facing away from the second wing 20 .

[0045] Specifically, a third protrusion 11 is provided on the surface of the first wing 10, and the third protrusion 11 can prevent other sliders from being attached to the surface of the first wing 10 over a large area, further improving the anti-sticking effect.

[0046] Optionally, there are multiple third protrusions 11, which are respectively distributed on opposite sides of the cap 40, so as to prevent the slider from sticking to the surfaces of the first wing 10 on opposite sides of the cap 40, and the anti-sticking effect is better.

[0047] In another embodiment of the present invention, refer to Figure 4 As shown, the surface of the first wing 10 of the slider facing away from the second wing 20 is recessed toward the second wing 20 at a position corresponding to the middle of the cap 40 to form a groove 12, and the two ends of the groove 12 extend out of the opposite sides of the cap 40 respectively.

[0048] Specifically, the groove 12 divides the large flat surface of the first wing 10 into a plurality of small areas, thereby preventing the sliders from sticking together due to large-area contact, and further improving the anti-sticking effect.

[0049] Optionally, the groove 12 is connected to the installation groove 12 on the cap 40 for installing the pull tab, so that the pull tab has a larger range of movement and good flexibility in use. The operation of the slider is smooth, convenient and fast, saving time and effort.

[0050] In another embodiment of the present invention, refer to Figure 1 As shown, a first slope 13 is provided at the edge of the first wing 10 of the slider, and the first slope 13 extends outwardly from the surface of the first wing 10 facing away from the second wing 20 and obliquely extends toward the second wing 20 and is connected to the side of the first wing 10.

[0051] Specifically, during the electroplating or painting process, the electrolyte or paint at the edge of the first wing 10 can be discharged along the first bevel 13 to prevent the electrolyte or paint from accumulating at the edge of the first wing 10. The electrolyte or paint is more evenly distributed on the slider and the appearance is more beautiful. In addition, after the electroplating or painting process is completed, the first bevel 13 can generate more reflected light outside the entire slider, so that the visual effect of the entire slider is three-dimensional.

[0052] Optionally, see Figure 5As shown, the first wing 10 is provided with a first inclined surface 13 on three sides close to the guide pillar 30, and the angle θ between the first inclined surface 13 and the surface of the first wing 10 facing away from the second wing 20 is 1 The first inclined surface 13 within the above angle range is greater than 100°, and generates more reflected light, so that the slider has a better visual effect.

[0053] Optionally, the area of ​​the surface of the first wing 10 facing away from the second wing 20 vertically projected on the second wing 20 is greater than or equal to 85% of the area of ​​the surface of the first wing 10 close to the second wing 20 vertically projected on the second wing 20. This can ensure that the first wing 10 has good strength and that the slider has a better visual effect.

[0054] In another embodiment of the present invention, refer to Figure 1 As shown, a second slope 23 is provided at the edge of the second wing 20 of the slider, and the second slope 23 extends obliquely outward from the surface of the second wing 20 facing away from the second wing 20 and toward the first wing 10 and is connected to the side of the second wing 20.

[0055] Specifically, during the electroplating or painting process, the electrolyte or paint at the edge of the second wing 20 can be discharged along the second bevel 23 to prevent the electrolyte or paint from accumulating at the edge of the second wing 20, so that the electrolyte or paint is more evenly distributed on the slider and the appearance is more beautiful; in addition, after the electroplating or painting process is completed, the second bevel 23 can generate more reflected light outside the entire slider, so that the visual effect of the entire slider is three-dimensional.

[0056] Optionally, see Figure 5 As shown, the three sides of the second wing 20 disposed near the guide pillar 30 are all provided with a second inclined surface 23, and the angle θ between the second inclined surface 23 and the surface of the second wing 20 facing away from the first wing 10 is 2 The second inclined surface 23 within the above angle range is greater than 100°, and generates more reflected light, so that the slider has a better visual effect.

[0057] Optionally, the area of ​​the surface of the second wing 20 facing away from the first wing 10 vertically projected on the first wing 10 is greater than or equal to 85% of the area of ​​the surface of the second wing 20 close to the first wing 10 vertically projected on the first wing 10. This can ensure that the first wing 10 has good strength and that the slider has a better visual effect.

[0058] In another embodiment of the present invention, refer to Figure 4 As shown, the edges of the first wing 10 and the second wing 20 of the slider are both provided with a chamfered arc surface 14 for smooth transition.

[0059] Specifically, the provision of the chamfered arc surface 14 makes the edges of the first wing 10 and the second wing 20 rounded and smooth, thereby preventing the slider from scratching fingers, clothes, etc. when in use.

[0060] Optionally, the chamfered arc surface 14 is arranged away from the peripheral portion of the guide pillar 30 and its two sides are respectively connected to the corresponding first inclined surface 13 and second inclined surface 23, so that the peripheral shape of the entire first wing 10 and the second wing 20 is flat and smooth to avoid edges.

[0061] Optionally, the radius of the rounded surface 14 is greater than 0.2 mm. This configuration makes the slider more beautiful and three-dimensional.

[0062] Optionally, a chamfered arc surface 14 can be provided on the edges of the first wing 10, the second wing 20, the guide column 30 and the cap 40, so that the shape of the entire slider is flat and smooth to avoid hooking clothes during use; of course, the radius value of the chamfered arc surface 14 at different positions can be selected according to the actual structure, which will not be repeated here.

[0063] In another embodiment of the present invention, a zipper is provided, comprising the above-mentioned slider.

[0064] The zipper of the embodiment of the present invention adopts the above-mentioned slider. During the electroplating or painting process of the slider, the slider is blocked by the first protrusion 21 and the cap 40, so that the other surfaces of the slider cannot be closely attached to the surface of the second wing over a large area and stick together. This solves the problem of slider sticking, reduces the rework rate of the slider, improves the success rate of electroplating or painting, and greatly reduces the production cost.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
