[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] A zipper is a connecting device that achieves opening and closing by interlocking or separating the chain teeth. It is widely used in clothing, bags, shoes, outdoor products and other fields. The two sides of the zipper in the thickness direction z are the inner and outer sides, respectively. When the two chain straps of the zipper are engaged, it is necessary to distinguish the front and back so that the inner and outer sides of the two chain straps correspond.

[0026] However, the appearance and feel of the inner and outer sides of the zipper teeth in related technologies are similar, making it difficult for users to quickly distinguish the inner and outer sides of the zipper strap. This increases the difficulty for users to distinguish the front and back when opening and closing the zipper, affecting the user experience.

[0027] To solve the above-mentioned technical problems, this application provides a zipper 100 and a zipper product using the zipper 100. The first chain band 001 and the second chain band 002 of the zipper 100 provided in this application are provided with protrusions 113 on the chain teeth 10. The protrusions 113 are located on the outside of the chain teeth 10, so as to facilitate the differentiation of the front and back of the chain band.

[0028] The following is about the combination Figure 1 , Figure 2 , Figure 3 and Figure 4 The zipper 100 provided in the embodiments of this application will be described.

[0029] It should be noted that the first direction in the following text is the x-direction shown in the figure, the second direction in the following text is the y-direction shown in the figure, and the thickness direction of the chain tooth mounting part 20 in the following text is the z-direction shown in the figure.

[0030] The zipper 100 provided in this application embodiment includes a first chain belt 001 and a second chain belt 002. Both the first chain belt 001 and the second chain belt 002 include a chain tooth mounting part 20 and a plurality of chain teeth 10.

[0031] like Figure 1 and Figure 2 As shown, the first chain belt 001 includes a chain tooth mounting part 20 and a plurality of chain teeth 10, and the second chain belt 002 includes a chain tooth mounting part 20 and a plurality of chain teeth 10. The plurality of chain teeth 10 of the first chain belt 001 have the same shape, and the plurality of chain teeth 10 of the second chain belt 002 have the same shape. The chain teeth 10 of the first chain belt 001 and the chain teeth 10 of the second chain belt 002 may be the same or different.

[0032] Chain teeth 10 are disposed on the edge of chain tooth mounting portion 20, and multiple chain teeth 10 are arranged at intervals along the first direction x. Each chain tooth 10 includes a first tooth portion 11 and a second tooth portion 12 arranged along the thickness direction z of chain tooth mounting portion 20. For any chain tooth 10, the first tooth portion 11 and the second tooth portion 12 are respectively located on both sides of the thickness direction z of chain tooth mounting portion 20. The first tooth portion 11 of the first chain belt 001 can mesh with the first tooth portion 11 of the second chain belt 002, and the second tooth portion 12 of the first chain belt 001 can mesh with the second tooth portion 12 of the second chain belt 002.

[0033] like Figure 1 and Figure 2 As shown, the chain tooth mounting part 20 extends along a plane parallel to the xOy plane shown in the figure. A plurality of chain teeth 10 are provided on the edge of the chain tooth mounting part 20 extending along the first direction x at one end in the second direction y. The plurality of chain teeth 10 of the first chain belt 001 are evenly spaced along the first direction x, and the plurality of chain teeth 10 of the second chain belt 002 are evenly spaced along the first direction x.

[0034] The chain tooth 10 includes a first tooth 11 disposed on one side of the chain tooth mounting portion 20 in the thickness direction z and a second tooth 12 disposed on the other side of the chain tooth mounting portion 20 in the thickness direction z. The first tooth 11 and the second tooth 12 are connected to form the chain tooth 10. The edge of the chain tooth mounting portion 20 is sandwiched between the first tooth 11 and the second tooth 12, thereby fixing the chain tooth 10 to the edge of the chain tooth mounting portion 20.

[0035] The chain teeth 10 of the first chain belt 001 and the chain teeth 10 of the second chain belt 002 both include a first tooth portion 11 and a second tooth portion 12. The first tooth portion 11 of the first chain belt 001 can be engaged between the two first tooth portions 11 of the second chain belt 002, thereby engaging the first tooth portion 11 of the first chain belt 001 with the first tooth portion 11 of the second chain belt 002. The second tooth portion 12 of the first chain belt 001 can be engaged between the two second tooth portions 12 of the second chain belt 002, thereby engaging the second tooth portion 12 of the first chain belt 001 with the second tooth portion 12 of the second chain belt 002.

[0036] The first tooth 11 has a protrusion 113 at one end opposite to the second tooth 12 in the thickness direction z of the chain tooth mounting part 20.

[0037] like Figure 1 and Figure 2 As shown, when the first chain belt 001 and the second chain belt 002 are engaged, the first tooth 11 of the first chain belt 001 and the first tooth 11 of the second chain belt 002 are located on the outside of the zipper 100, and the second tooth 12 of the first chain belt 001 and the second tooth 12 of the second chain belt 002 are located on the inside of the zipper 100. The end of the first tooth 11 facing away from the second tooth 12 is provided with a protrusion 113, so that the protrusion 113 on the surface of the first tooth 11 can mark the inside and outside of the first chain belt 001 and the second chain belt 002. Thus, before the first chain belt 001 and the second chain belt 002 are engaged, the user can engage the first tooth 11 of the first chain belt 001 and the first tooth 11 of the second chain belt 002 according to the position of the protrusion 113, and engage the second tooth 12 of the first chain belt 001 and the second tooth 12 of the second chain belt 002 accordingly.

[0038] The beneficial effects of the zipper 100 provided in this application embodiment are as follows: Compared with the prior art, when the chain teeth 10 of the first chain belt 001 and the chain teeth 10 of the second chain belt 002 of the zipper 100 provided in this application embodiment are engaged with each other, the protrusions 113 of the first chain belt 001 and the protrusions 113 of the second chain belt 002 are located on the same side of the chain tooth mounting portion 20. This makes it easier for the user to distinguish the inner and outer sides of the first chain belt 001 and the second chain belt 002 by observing the distribution of the protrusions 113 or touching the surface of the chain teeth 10. This gives the zipper 100 provided in this application embodiment the advantage of being easy to distinguish the front and back of the zipper 100.

[0039] Furthermore, by providing a protrusion 113 on the side of the first tooth 11 facing away from the second tooth 12, the aesthetics of the zipper 100 provided in this embodiment are enhanced. The first tooth 11 of the first chain belt 001 and the first tooth 11 of the second chain belt 002 mesh with each other, and the second tooth 12 of the first chain belt 001 and the second tooth 12 of the second chain belt 002 mesh with each other, thereby improving the meshing strength of the first chain belt 001 and the second chain belt 002. Compared with the related art where only the chain teeth 10 located on one side of the chain tooth mounting portion 20 mesh with each other, the zipper 100 provided in this embodiment has the advantage of balancing better aesthetics and higher meshing strength.

[0040] In some embodiments provided in this application, such as Figure 1 and Figure 2As shown, the multiple chain teeth 10 include multiple first chain teeth 101 and multiple second chain teeth 102, the chain tooth mounting part 20 includes a first mounting part 21 and a second mounting part 22, the first chain belt 001 includes a first mounting part 21 and multiple first chain teeth 101, and the second chain belt 002 includes a second mounting part 22 and multiple second chain teeth 102.

[0041] The first chain tooth 101 is provided with a first water-blocking flange 101a, and the second chain tooth 102 is provided with a second water-blocking flange 102a. When the first chain tooth 101 and the second chain tooth 102 mesh with each other, at least a portion of the first water-blocking flange 101a and at least a portion of the second water-blocking flange 102a abut against each other in the thickness direction z of the chain tooth mounting portion 20.

[0042] like Figure 3 and Figure 4 As shown, a first water-blocking flange 101a protrudes along the first direction x and the second direction y onto the chain teeth 10 of the first chain belt 001, and a second water-blocking flange 102a protrudes along the first direction x and the second direction y onto the chain teeth 10 of the second chain belt 002. When the first chain belt 001 and the second chain belt 002 mesh with each other, the portion of the first water-blocking flange 101a located on the chain teeth 10 of the first chain belt 001 in the first direction x and the portion of the second water-blocking flange 102a located on the chain teeth 10 of the second chain belt 002 in the first direction x overlap and abut against each other in the thickness direction z of the chain tooth mounting portion 20. This seals the gap between the chain teeth 10 of the first chain belt 001 and the chain teeth 10 of the second chain belt 002 by the first water-blocking flange and the second water-blocking flange 102a, thereby improving the sealing and waterproof performance of the zipper 100 provided in this embodiment.

[0043] In some embodiments provided in this application, such as Figure 3 and Figure 4 As shown, the first water-blocking flange 101a is integrally formed with the first tooth portion 11 of the first chain tooth 101, and the second water-blocking flange 102a is integrally formed with the second tooth portion 12 of the second chain tooth 102.

[0044] like Figure 3 and Figure 4 As shown, the orthographic projection of the first tooth 11 of the first chain belt 001 in the thickness direction z of the chain tooth mounting portion 20 is located outside the orthographic projection of the second tooth 12 of the first chain belt 001 in the thickness direction z of the chain tooth mounting portion 20, so that the edge portion of the first tooth 11 of the first chain belt 001 protrudes to the outside of the edge of the second tooth 12 of the first chain belt 001 to form a first water-blocking flange 101a.

[0045] like Figure 3 and Figure 4As shown, the orthographic projection profile of the second tooth 12 of the second chain belt 002 in the thickness direction z of the chain tooth mounting portion 20 is located outside the orthographic projection profile of the first tooth 11 of the second chain belt 002 in the thickness direction z of the chain tooth mounting portion 20, so that the edge portion of the second tooth 12 of the second chain belt 002 protrudes to the outside of the edge of the first tooth 11 of the second chain belt 002 to form a second water-blocking flange 102a.

[0046] In some embodiments provided in this application, such as Figure 1 As shown, some of the first teeth 11 and the protrusions 113 are misaligned in the thickness direction z of the chain tooth mounting portion 20.

[0047] like Figure 1 As shown, the protrusion 113 is provided on one side of a portion of the first tooth 11 in the thickness direction z of the chain tooth mounting portion 20, and the other portion of the first tooth 11 is not covered by the protrusion 113, thereby creating a height difference between the portion of the first tooth 11 not covered by the protrusion 113 and the protrusion 113, thereby increasing the tactile feel of the protrusion 113, allowing the user to judge the inner or outer side of the first chain belt 001 or the second chain belt 002 by touch alone, and to arrange the first tooth 11 and the second tooth 12 of the first chain belt 001 and the first tooth 11 and the second tooth 12 of the second chain belt 002 in a corresponding manner.

[0048] In some embodiments provided in this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the first tooth portion 11 includes a first connecting portion 111 and a first engaging portion 112. The first engaging portion 112 of the first chain belt 001 can engage with the first engaging portion 112 of the second chain belt 002. The first connecting portion 111 is provided on one side of the chain tooth mounting portion 20 in its thickness direction z. The first engaging portion 112 is connected to the first connecting portion 111, and the first engaging portion 112 protrudes from the edge of the chain tooth mounting portion 20. The orthographic projection of the first connecting portion 111 in the thickness direction z of the chain tooth mounting portion 20 is located inside the orthographic projection contour of the protrusion 113 in the thickness direction z of the chain tooth mounting portion 20.

[0049] like Figure 1As shown, the first connecting part 111 is projected onto the tooth mounting part 20 within the orthographic projection outline of the tooth mounting part 20 in its thickness direction z. The first connecting part 111 is used to fix the first engaging part 112 onto the tooth mounting part 20. The first connecting part 111 and the first engaging part 112 are integrally formed. The first engaging part 112 is located on one side of the first connecting part 111 in the second direction y. The first engaging part 112 has grooves on both sides in the first direction x. When the first chain 001 and the second chain 002 are engaged, the first engaging part 112 of the first chain 001 can be engaged in the grooves of two adjacent first engaging parts 112 of the second chain 002.

[0050] A portion of the protrusion 113 is provided on the side of the first connecting portion 111 away from the chain tooth mounting portion 20, and the portion of the protrusion 113 covers the surface of the first connecting portion 111.

[0051] Therefore, by increasing the thickness of the first chain tooth 101 portion through the protrusion 113, the structural strength of the first chain tooth 101 portion is improved, thereby enabling the zipper 100 provided in this embodiment to have higher physical strength.

[0052] In some embodiments provided in this application, such as Figure 1 As shown, a portion of the protrusion 113 is located on the side of the first engagement portion 112 away from the chain tooth mounting portion 20, and the protrusion 113 extends to the end of the first engagement portion 112 away from the connecting portion.

[0053] like Figure 1 As shown, a portion of the protrusion 113 is located on the side of the first connecting portion 111 away from the chain tooth mounting portion 20, and another portion of the protrusion 113 is located on the side of the first engaging portion 112 away from the chain tooth mounting portion 20, and the protrusion 113 extends from one end of the first engaging portion 112 in the second direction y to the other end of the first engaging portion 112 in the second direction y.

[0054] Therefore, part of the first engagement portion 112 is not covered by the protrusion 113, thereby increasing the surface roughness of the first tooth portion 11 by the protrusion 113, making it easier for the user to distinguish the first tooth portion 11 and the second tooth portion 12 by touching the surface of the chain tooth 10, so that the zipper 100 provided in this application embodiment has the advantage of being easy to distinguish the front and back of the zipper 100.

[0055] In some embodiments provided in this application, such as Figure 2 As shown, the second tooth 12 is provided with a recess 124, which is recessed along the thickness direction z of the chain tooth mounting part 20 on the surface of the second tooth 12 away from the first tooth 11.

[0056] like Figure 2As shown, the groove 124 is recessed on the side of the second tooth 12 opposite to the first tooth 11, so that the user can distinguish the first tooth 11 and the second tooth 12 by touching the surface of the chain tooth 10, so that the zipper 100 provided in this application embodiment has the advantage of being easy to distinguish the front and back of the zipper 100.

[0057] In some embodiments provided in this application, such as Figure 2 and Figure 4 As shown, the second tooth portion 12 includes a second connecting portion 121 and a second engaging portion 122. The second engaging portion 122 of the first chain belt 001 can engage with the second engaging portion 122 of the second chain belt 002. The second connecting portion 121 is provided on one side of the chain tooth mounting portion 20 in its thickness direction z. The second engaging portion 122 is connected to the second connecting portion 121, and the second engaging portion 122 protrudes from the edge of the chain tooth mounting portion 20.

[0058] like Figure 2 and Figure 4 As shown, the second connecting part 121 is located within the orthographic projection outline of the chain tooth mounting part 20 in its thickness direction z on the orthographic projection of the chain tooth mounting part 20. The second connecting part 121 is used to fix the second engaging part 122 on the chain tooth mounting part 20. The chain tooth 10 is mounted on the edge of the chain tooth mounting part 20 by clamping the edge of the chain tooth mounting part 20 with the first connecting part 111 and the second connecting part 121.

[0059] The second connecting part 121 and the second engaging part 122 are integrally formed. The second engaging part 122 is located on one side of the second connecting part 121 in the second direction y. The second engaging part 122 has grooves on both sides in the second direction y. When the first chain 001 and the second chain 002 are engaged, the second engaging part 122 of the first chain 001 can be engaged in the grooves of two adjacent second engaging parts 122 of the second chain 002.

[0060] In some embodiments provided in this application, such as Figure 2 and Figure 4 As shown, the second connecting portion 121 has a thin edge portion 123 at one end away from the second engaging portion 122. The dimension of the thin edge portion 123 in the thickness direction z of the chain tooth mounting portion 20 is smaller than the dimension of the second connecting portion 121 in the thickness direction z of the chain tooth mounting portion 20, so that a groove 124 is formed on the side of the thin edge portion 123 away from the chain tooth mounting portion 20.

[0061] like Figure 2 and Figure 4 As shown, for any chain tooth 10, the thin edge portion 123 and the second meshing portion 122 are located on both sides of the second connecting portion 121 in the second direction y, respectively. The thin edge portion 123 is connected to the chain tooth mounting portion 20, and the thin edge portion 123, the second connecting portion 121 and the second meshing portion 122 are integrally formed.

[0062] Therefore, on the one hand, by setting the thin edge portion 123, it is easier for users to distinguish the first tooth portion 11 and the second tooth portion 12 according to the touch. On the other hand, by setting the thin edge portion 123, the thickness of the edge of the zipper 100 can be reduced, so that the zipper 100 provided in this application embodiment has the advantage of being thin and light.

[0063] In some embodiments provided in this application, such as Figure 2 As shown, the width dimension W1 of the thin edge portion 123 in the first direction x gradually decreases in the direction away from the second connecting portion 121.

[0064] like Figure 2 As shown, the width dimension of the thin edge 123 in the first direction x is as follows Figure 2 As shown in W1, when two adjacent chain teeth 10 rotate about an axis parallel to the thickness direction z of the chain tooth mounting portion 20, the thin edges 123 of the two adjacent chain teeth 10 can avoid each other.

[0065] In some embodiments provided in this application, such as Figure 1 and Figure 2 As shown, both the first chain belt 001 and the second chain belt 002 include a wire core 30. The wire core 30 is disposed on the edge of the chain tooth mounting portion 20 and is sandwiched between the first tooth portion 11 and the second tooth portion 12. The end of the first tooth portion 11 and the end of the second tooth portion 12 of the first chain belt 001 can abut against the wire core 30 of the second chain belt 002.

[0066] The zipper products provided in this application are described below.

[0067] The zipper products provided in this application include the zipper 100 in any of the above embodiments. The zipper products provided in this application can be used for clothing, shoes, bags, etc., where the internal space is opened and closed via the zipper 100. The zipper 100 provided in this application has the advantage of easily distinguishing the front and back, thereby reducing the defect rate of the zipper products provided in this application and reducing processing difficulty.

[0068] The above are merely preferred embodiments of this application and are not intended to limit this application.
