[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0034] In order to make the technical personnel in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0035] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left" and "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the position or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0036] The purpose of the present application is to provide a stop component that can reduce the gap between two tapes installed with a lower stop.

[0037] To achieve the above object, the present application provides the following technical solutions.

[0038] Please refer to Figures 1 to 3 The stop component comprises a main body 1, a toothed chain 02 installed on a pair of cloth belts 01, the main body 1 comprises a containing groove 11 arranged on both sides thereof for pressing the cloth belts 01, and a core 12 between the two containing grooves 11, the side of the two containing grooves 11 close to each other is respectively provided with a first guide channel 13 and a second guide channel 14, the end of the first guide channel 13 and the second guide channel 14 close to the toothed chain 02 is respectively provided with a first inlet channel 131 and a second inlet channel 141 for the edges of the cloth belts 01 to enter, and the other end is respectively provided with a first outlet channel 132 and a second outlet channel 142, the first guide channel 13 and the second guide channel 14 are used for guiding the two cloth belts 01 close to each other, and the distance between the first inlet channel 131 and the second inlet channel 141 is greater than the distance between the first outlet channel 132 and the second outlet channel 142.

[0039] Specifically, the opposite sides of the two cloth belts 01 are respectively provided with the toothed chains 02, and the stop component is installed at the end position of the two toothed chains 02 and between the two cloth belts 01, and the stop component is used for limiting the travel range of the puller 04 beyond the toothed chain 02, the stop component comprises the main body 1, the inside of the main body 1 is provided with the two containing grooves 11, the inside of the two containing grooves 11 is respectively provided with the first guide channel 13 and the second guide channel 14, the two containing grooves 11 can press the cloth belts 01 on both sides, and the edges of the cloth belts 01 are provided with a cloth belt 03, so that the cloth belt 03 can pass through the first guide channel 13 and the second guide channel 14 respectively.

[0040] That is to say, the left cloth belt 01 is pressed in the containing groove 11 on the left side of the main body 1, the cloth belt 03 of the left cloth belt 01 enters through the first inlet channel 131 and extends out of the first outlet channel 132, and the right cloth belt 01 is pressed in the containing groove 11 on the right side, and the cloth belt 03 of the right cloth belt 01 enters through the second inlet channel 141 and extends out of the second outlet channel 142, so as to complete the installation of the stop component. However, it should be noted that the first guide channel 13 and the second guide channel 14 have the function of guiding the cloth belt 03 close to each other during the inlet to outlet process, and in this embodiment, the distance between the first inlet channel 131 and the second inlet channel 141 is greater than the distance between the first outlet channel 132 and the second outlet channel 142, in other words, after the cloth belt 03 of the two cloth belts 01 is guided through the first guide channel 13 and the second guide channel 14, the gap between the two cloth belts 03 will be greatly reduced when the cloth belt 03 extends out of the outlet.

[0041] In one embodiment, the first guide channel 13 is inclined from the left side of the main body 1 to the middle of the main body 1 towards the core 12, and the second guide channel 14 is inclined from the right side of the main body 1 to the middle of the main body 1 towards the core 12, so that the second guide channel 14 guides the end of the tape 01 into the main body 1 to bend, so that the end of the tape 01 can be close to the other side of the tape 01, and finally the belt 03 will be returned from the first outlet channel 132 and the second outlet channel 142, so that the end of the tape 01 outside the stop component is kept within a certain orientation range, realizing the stability of the small gap between the two tapes 01. The first guide channel 13 and the second guide channel 14 can effectively limit the movement of the tape 01 while extending the trajectory of the belt 03 at the side edge of the end of the tape 01, so that the tape 01 can be stably kept in a certain movement trajectory. That is, by changing the positions of the first inlet channel 131 and the second inlet channel 141, the first outlet channel 132 and the second outlet channel 142, the starting point and the ending point of the belt 03 at the side edge of the tape 01 in the main body 1 are determined, so that the position and the bending angle of the tape 01 can be determined within a certain range, and the angle of the tape 01 extending out of the main body 1 is controlled by the orientation of the first outlet channel 132 and the second outlet channel 142, so that the tape 01 can be close to the other side of the tape 01 at the expected inclination angle.

[0042] In this way, the gap between the two tapes 01 caused by the existence of the toothed chain 02 can be minimized by the stop component, thereby increasing the overall beauty of the stop component zipper.

[0043] In addition, in this application, the stop component can be located at the upper end of the tape 01 or at the lower end of the tape 01, that is, the upper stop or the lower stop of the zipper. When the stop component is the lower stop, the upper surface of the main body 1 of the stop component is provided with a fitting part that matches the lowermost tooth shape of the tape 01 on the same side, and the guide channel on the same side can also be adapted to extend to the fitting part. By reducing the gap between the stop component and the tooth through the fitting part, the inlet channel of the guide channel opened on the upper surface of the fitting part can also ensure that part of the side edge of the tape 01 can effectively enter the main body 1, and the fitting part will not interfere with the action between the tape 01 and the main body 1. When the stop component is the upper stop, the principle is similar, except that the position of the fitting part is changed up and down.

[0044] Further, with the change of the bending of the adjacent side of the tape 01, the edges of the two tapes 01 far away from each other are simultaneously bent inward, that is, when the end of the tape 01 is not in a bent state, the tape 01 itself is a common tape 01 with a vertical tape head, which can be produced in a conventional production manner without the need for special production of the tape 01 with a bent end. Only when the stop component is installed, the end of the tape 01 can be kept in a bent state, which saves production cost and efficiency.

[0045] As preferred, the two accommodating grooves 11 and the first guide channel 13 and the second guide channel 14 are symmetrically arranged on both sides of the core 12, and the first guide channel 13 and the second guide channel 14 are close to each other towards the corresponding first outlet channel 132 and the second outlet channel 142.

[0046] Specifically, the two accommodating grooves 11 are symmetrically arranged about the core 12, and the first guide channel 13 and the second guide channel 14 are also symmetrically arranged about the core 12, that is, the first inlet channel 131 and the second inlet channel 141, and the first outlet channel 132 and the second outlet channel 142 are also symmetrically arranged about the core 12; however, it should be noted that the distance between the first inlet channel 131 and the second inlet channel 141 is greater than the distance between the first outlet channel 132 and the second outlet channel 142; the distance between the first inlet channel 131 and the second inlet channel 141 needs to meet the space for meshing of the toothed chain 02, but the distance between the first outlet channel 132 and the second outlet channel 142 needs to be reduced to guide the gap between the two protruding ribs 03. Among them, the distance between the first outlet channel 132 and the second outlet channel 142 can be adjusted according to actual conditions, but the two are preferably arranged in close contact.

[0047] As preferred, the second guide channel 14 is parallel to the extension direction of the toothed chain 02, and the first guide channel 13 extends towards the end of the first outlet channel 132.

[0048] The channel where the stop component cooperates with the rib 03 of the belt 01 is usually two and is arranged on the left and right sides of the main body 1 and cooperates with the left and right belts 01, wherein the number of the curved guide channel can be one or two.

[0049] In one embodiment, as shown in Figure 4 only one curved limiting channel, the other guide channel in the main body 1 cooperating with the belt 01 is a conventional vertical channel, specifically, the left side is curved as the first guide channel 13, and the right side is vertical as the second guide channel 14, and the second guide channel 14 is only used for the stop component to be effectively connected to the belt 01, at this time, the bending angle of the first guide channel 13 to the belt 01 needs to be larger, that is, the transition channel 15 in the first guide channel 13 has a larger bending angle, and the gap between the belts 01 is closer to the other side of the belt 01; in this way, the gap between the two belts 01 can also be reduced.

[0050] As preferred, the first guide channel 13 and the second guide channel 14 respectively comprise a transition channel 15 between the first inlet channel 131 and the first outlet channel 132, and between the second inlet channel 141 and the second outlet channel 142, and the two transition channels 15 respectively communicate the first inlet channel 131 and the first outlet channel 132, and the second inlet channel 141 and the second outlet channel 142.

[0051] That is, the first guide channel 13 and the second guide channel 14 further comprise a transition channel 15, which is specifically an inclined segment channel communicating the first inlet channel 131 and the first outlet channel 132, and the second inlet channel 141 and the second outlet channel 142, wherein as shown in Figure 2 and Figure 3 The lower end of the transition channel 15 is closer to the middle of the core 12 than the upper end.

[0052] In an embodiment, the first inlet channel 131 and the second inlet channel 141 are both vertically arranged, that is, the axes of the two are parallel to the extension direction of the toothed chain 02, and such arrangement can facilitate the insertion of the reinforcing rib 03 of the cloth belt 01 into the first inlet channel 131 and the second inlet channel 141; and the arrangement of the transition channel 15 can make the cloth belt 01 after bending more smoothly transition to the outlet, so that the bending of the end of the cloth belt 01 is more natural and is not easy to be excessively twisted.

[0053] As preferred, the transition channel 15 is in an overall arc-shaped structure or a straight line type structure.

[0054] Further, the overall shape of the transition channel 15 can also be a circular arc, that is, the smooth connection of the first inlet channel 131 and the first outlet channel 132, and such arrangement is conducive to the insertion of the reinforcing rib 03; the transition channel 15 can also be selected as a straight line type or a broken line structure according to actual conditions, which is not limited herein.

[0055] In an embodiment, the axes of the first inlet channel 131 and the first outlet channel 1132 coincide, and the axes of the second inlet channel 141 and the second outlet channel 142 coincide.

[0056] That is, the first guide channel 13 and the second guide channel 14 are both straight inclined channels, that is, the axes of the first inlet channel 131 and the first outlet channel 132 coincide, and the axes of the second inlet channel 141 and the second outlet channel 142 coincide, and as shown in Figure 5 Therefore, the reinforcing rib 03 of the cloth belt 01 will directly pass through the first guide channel 13 and the second guide channel 14.

[0057] In general, the two guide channels can be symmetrically arranged on the left and right sides in the main body 1, or can be appropriately offset in position, or the orientation, angle, length, width, diameter, etc. can be changed as needed.

[0058] In an embodiment, the main body 1 as a whole can be a U-shaped structure.

[0059] Specifically, as shown in Figure 6 , the main body 1 also includes an organic core 12, which is located between the two guide channels and the receiving groove 11, and is used to separate the two guide channels and the ribbon 01 in the receiving groove 11, so that the two ribbons 01 in the main body 1 do not interfere with each other and affect the gap reduction effect between the ribbons 01. The shape of the core 12 is also adapted to the shape of the two side guide channels, and the width gradually decreases from the upper surface to the lower surface of the main body 1.

[0060] In addition, in this embodiment, the transition channel 15 in the middle of the first guide channel 13 and the second guide channel 14 can be an arc-shaped structure, or a straight line structure.

[0061] Of course, the shape of the main body 1 as a whole can be adjusted according to actual conditions, which is not specifically limited herein.

[0062] Optionally, the first outlet channel 132 and the second outlet channel 142 are axially parallel to the extension direction of the toothed chain 02.

[0063] That is, as an option, the first outlet channel 132 and the second outlet channel 142 can be arranged to abut each other while the axes are parallel to each other, so that the protruding ribs 03 can be kept parallel to each other, as shown in Figure 3 , Figure 9 and Figure 10 , so that the overall appearance of the zipper can be ensured.

[0064] Optionally, the axes of the first outlet channel 132 and the second outlet channel 142 cross each other in a direction away from the toothed chain 02.

[0065] Specifically, as an option, the axes of the first outlet channel 132 and the second outlet channel 142 are close to each other in the downward direction, that is, the two axes cross together downward, so that the ribbons 01 of the protruding stop members overlap, as shown in Figure 7 .

[0066] Optionally, the axes of the first outlet channel 132 and the second outlet channel 142 are away from each other in a direction away from the toothed chain 02.

[0067] As an alternative, the axes of the first and second exit channels 132, 142 are mutually diverging in the downward direction, i.e. the two exit channels diverge downwardly, so that the webbing 01 passing through the stop member is forked, as shown in Figure 8 .

[0068] In general, the angle of inclination of the first and second exit channels 132, 142 relative to the length of the webbing 01 is preferably between -15 and 15 degrees, i.e. the axes of the exit channels of the second guide portions of the two guide channels can be diverging, parallel or intersecting, as shown in Figure 8 In the diverging state, the lower ends of the webbing 01 diverge to the left and right, the upper gap of the gap between the ends of the webbing 01 is small, and the lower gap is large. After the zipper is sewn onto the garment, the exposed part of the end of the webbing 01 still has a small gap, as shown in Figure 3 , Figure 9 and Figure 10 In the parallel state, the lower ends of the webbing 01 are parallel to each other, and the gap size is the distance between the two exit channels, the closer the distance, the smaller the gap. In the intersecting state, the two lower ends of the webbing 01 intersect with each other, and the left and right webbings 01 overlap each other, and there is basically no gap or only a small gap at the contact exit. The preferred embodiment is that the exit channels of the two guide channels are in a parallel state, and the side edges of the left and right webbings 01 are in contact, so as to realize the no-gap state between the ends of the zipper webbing 01. Figure 7

[0069] Preferably, the main body is integrally formed by injection molding or formed by metal riveting.

[0070] In addition, in the present embodiment, the stop member is of an integral structure, and the material thereof can be an injection molding material or a metal material. When the stop member is an injection molding material, the stop member is formed on the webbing 01 by injection molding, and the stop member formed by injection molding and cooling restricts the bending of the reinforcing rib 03 of the webbing 01 to a close state, maintains a no-gap or reduced-gap state, and is more convenient and efficient to process. When the stop member is a metal material, the stop member is first formed, and then the stop member is clamped on the webbing 01, so that the webbing 01 is maintained in an extending state along the inner guide channel of the metal stop member, and a no-gap or reduced-gap state of the webbing 01 is maintained, and the processing is more flexible, and the stop is easy to replace and maintain.

[0071] The present application also provides a zipper comprising the stop member described above, and further comprising: a pair of webbings 01, a toothed chain 02 arranged on opposite sides of the webbings 01, respectively, and a puller 04 for advancing or retreating along the toothed chain 02 to engage or disengage the toothed chain 02; and the zipper has all the beneficial effects of the stop member described above.
