In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0035] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.
[0036] like Figures 1 to 3 As shown, one embodiment of this application provides a waterproof zipper, including a first toothed chain 100 and a second toothed chain 200. Both the first toothed chain 100 and the second toothed chain 200 include a plurality of meshing teeth 300 spaced apart along the length direction. The plurality of meshing teeth 300 of the first toothed chain 100 and the plurality of meshing teeth 300 of the second toothed chain 200 mesh with each other. Each meshing tooth 300 includes a front tooth portion 310 and a rear tooth portion 320, which are arranged sequentially along the thickness direction; along the length direction, the front tooth portion 310 and the rear tooth portion 320 are staggered. The thickness direction refers to the thickness direction of the waterproof zipper, and the length direction refers to the length direction of the waterproof zipper. In this embodiment, the length direction of the waterproof zipper is also the length direction of the first toothed chain 100 and the second toothed chain 200. It is worth noting that the thickness direction mentioned below refers to the thickness direction of the waterproof zipper, and the length direction mentioned below refers to the length direction of the waterproof zipper. In the embodiments of this application, the length direction can be horizontal, vertical, or any other direction. For ease of description, the following description will use a vertical length direction as an example.
[0037] It is worth noting that both the first tooth chain 100 and the second tooth chain 200 include a plurality of meshing teeth 300 spaced apart along the length direction. Specifically, both the first tooth chain 100 and the second tooth chain 200 include a plurality of meshing teeth 300, with the plurality of meshing teeth 300 of the first tooth chain 100 spaced apart along the length direction and the plurality of meshing teeth 300 of the second tooth chain 200 spaced apart along the length direction.
[0038] In the embodiments of the present application, the front tooth portion 310 and the rear tooth portion 320 of the meshing tooth 300 can be an integral structure or a split structure. When the front tooth portion 310 and the rear tooth portion 320 of the meshing tooth 300 are a split structure, the front tooth portion 310 and the rear tooth portion 320 can be directly connected or indirectly connected. In some examples, the front tooth portion 310 and the rear tooth portion 320 can be directly connected by means of gluing, clamping or melting, or in other examples, the first tooth chain 100 and the second tooth chain 200 each further include a waterproof belt 400, and the plurality of meshing teeth 300 of the first tooth chain 100 are each mounted on the waterproof belt 400 of the first tooth chain 100, and the plurality of meshing teeth 300 of the second tooth chain 200 are each mounted on the waterproof belt 400 of the second tooth chain 200. Alternatively, the front tooth portion 310 and the rear tooth portion 320 of the meshing tooth 300 are each mounted on the waterproof belt 400, and the front tooth portion 310 and the rear tooth portion 320 are indirectly connected through the waterproof belt 400. Alternatively, the front tooth portion 310 and the rear tooth portion 320 of the meshing tooth 300 are each mounted on the waterproof belt 400, and part of the structure of the front tooth portion 310 extends to one side of the waterproof belt 400 along a direction parallel to the waterproof belt 400, and the rear tooth portion 320 extends to the same side of the waterproof belt 400 along the same direction, and the structure of the front tooth portion 310 and the rear tooth portion 320 extending to one side of the waterproof belt 400 is connected.
[0039] In the embodiments of the present application, the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 are meshed, specifically, the front tooth portion 310 of the plurality of meshing teeth 300 of the first tooth chain 100 is meshed with the front tooth portion 310 of the plurality of meshing teeth 300 of the second tooth chain 200, and the rear tooth portion 320 of the plurality of meshing teeth 300 of the first tooth chain 100 is meshed with the rear tooth portion 320 of the plurality of meshing teeth 300 of the second tooth chain 200.
[0040] Since the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 are spaced apart along the length direction, when the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 are engaged, the meshing lines are formed between the mutually engaged front tooth portions 310, and the meshing lines corresponding to each front tooth portion 310 are respectively located on the opposite sides of the front tooth portion 310 spaced apart along the length direction; the meshing lines are also formed between the mutually engaged rear tooth portions 320, and the meshing lines corresponding to each rear tooth portion 320 are respectively located on the opposite sides of the rear tooth portion 320 spaced apart along the length direction. Therefore, by arranging the front tooth portion 310 and the rear tooth portion 320 of the meshing tooth 300 to be staggered along the length direction, the front tooth portion 310 can cover the meshing line between the rear tooth portion 320 of the meshing tooth 300 of the first tooth chain 100 and the rear tooth portion 320 of the meshing tooth 300 of the second tooth chain 200, so as to prevent the water flow from passing through the gap between the mutually engaged rear tooth portions 320; similarly, the rear tooth portion 320 can cover the meshing line between the front tooth portion 310 of the meshing tooth 300 of the first tooth chain 100 and the front tooth portion 310 of the meshing tooth 300 of the second tooth chain 200, so as to prevent the water flow from passing through the gap between the mutually engaged front tooth portions 310. Thus, the engagement area between the first tooth chain 100 and the second tooth chain 200 (the area where the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 are engaged) is better sealed, and the waterproof effect of the waterproof zipper is effectively improved.
[0041] In one possible design, as shown in FIGS. 1 and 2, the front tooth portion 310 has a first front meshing surface 311 and a second front meshing surface 312 on the opposite sides thereof along the length direction, and the rear tooth portion 320 has a first rear meshing surface 321 and a second rear meshing surface 322 on the opposite sides thereof along the length direction. Figure 3 and Figure 4 As shown in FIGS. 1 and 2, the projection of the first front meshing surface 311 is located within the projection of the rear tooth portion 320, the projection of the second front meshing surface 312 is located outside the projection of the rear tooth portion 320, the projection of the second rear meshing surface 321 is located within the projection of the front tooth portion 310, and the projection of the first rear meshing surface 322 is located outside the projection of the front tooth portion 310.
[0042] The first front meshing surface 311 and the second front meshing surface 312 specifically refer to the opposite sides of the structure of the front tooth portion 310 located on the opposite sides of the above-mentioned engagement area and spaced apart along the length direction. The first rear meshing surface 321 and the second rear meshing surface 322 specifically refer to the opposite sides of the structure of the rear tooth portion 320 located on the opposite sides of the above-mentioned engagement area and spaced apart along the length direction.
[0043] For ease of description, the front tooth portion 310 of the first tooth chain 100 is referred to as the first front tooth portion, the rear tooth portion 320 of the first tooth chain 100 is referred to as the first rear tooth portion, the front tooth portion 310 of the second tooth chain 200 is referred to as the second front tooth portion, and the rear tooth portion 320 of the second tooth chain 200 is referred to as the second rear tooth portion. When the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 mesh, the first front tooth portion is located between two adjacent second front tooth portions in the second tooth chain 200. A meshing line is formed between the first front meshing surface 311 of the first front tooth portion and the second front meshing surface 312 of the second front tooth portion directly opposite to the first front meshing surface 311 of the second front tooth portion. When the plurality of meshing teeth 300 of the first tooth chain 100 and the plurality of meshing teeth 300 of the second tooth chain 200 mesh, the first rear tooth portion is located between two adjacent second rear tooth portions in the second tooth chain 200. A meshing line is formed between the first rear meshing surface 321 of the first rear tooth portion and the second rear meshing surface 322 of the second rear tooth portion directly opposite the first rear meshing surface 321. A meshing line is formed between the second rear meshing surface 322 of the first rear tooth portion and the first rear meshing surface 321 of the second rear tooth portion directly opposite the second rear meshing surface 322.
[0044] Therefore, according to the above arrangement, the front teeth 310 can cover the meshing line between each of the first rear teeth and the second rear teeth to a certain extent, and the rear teeth 320 can cover the meshing line between each of the first front teeth and the second front teeth, so as to improve the waterproof effect of the waterproof zipper.
[0045] In one possible design, such as Figures 3 to 5 As shown in any of the figures, the area where the multiple meshing teeth 300 of the first tooth chain 100 mesh with the meshing teeth 300 of the second tooth chain 200 is the meshing area. The front tooth portion 310 also has a guide surface 313 on at least one side in the length direction, and the liquid can flow along the guide surface 313 in a direction away from the meshing area.
[0046] In practical applications, the front teeth 310 are located on the outward-facing side of the product, and the rear teeth 320 are located on the inward-facing side of the product. For example, when the waterproof zipper provided in this embodiment is applied to clothing, the front teeth 310 are located on the outer side of the clothing, and the rear teeth 320 are located on the inner side. With this configuration, when rainwater or other liquids drip onto the front teeth 310, the liquid can flow down along the guide surface 313 of the front teeth 310, thereby preventing the possibility of liquid penetrating into the product through the meshing area, further improving the waterproof effect of the waterproof zipper.
[0047] In this embodiment, the rear tooth portion 320 can adopt the shape design of a common meshing tooth, and the specific shape of the rear tooth portion 320 is not limited in too much.
[0048] In one possible design, the flow guide surface 313 on one side of the front tooth 310 in the length direction gradually inclines to the other side of the front tooth 310 in the length direction in the direction away from the rear tooth 320 in the thickness direction, i.e. in the direction from the rear tooth 320 to the front tooth 310. In this way, liquid on the flow guide surface 313 above the front tooth 310 can flow down along the flow guide surface 313 in the direction away from the rear tooth 320, reducing the possibility of liquid accumulation above the front tooth 310, and thus improving the waterproof effect of the waterproof zipper.
[0049] In another possible design, the front tooth 310 includes a first head and a first tail connected to each other, the first head is located in the engagement area, the first head has a first front engagement surface 311 and a second front engagement surface 312 on opposite sides in the length direction respectively, the first tail is located on one side of the first head in the width direction away from the engagement area, and the first tail has a flow guide surface 313 on at least one side in the length direction. The width direction is the width direction of the waterproof zipper, and the width direction, the length direction and the thickness direction are perpendicular to each other. In the direction from the first head to the first tail, the flow guide surface 313 on one side of the front tooth 310 in the length direction gradually inclines to the other side of the front tooth 310 in the length direction. In this way, liquid on the flow guide surface 313 above the front tooth 310 can flow down along the flow guide surface 313 in the direction away from the engagement area, so as to avoid liquid entering the engagement area along the flow guide surface 313, and thus improve the waterproof effect of the waterproof zipper.
[0050] In yet another possible design, as shown in Figure 3 and Figure 5 In the direction from the first head to the first tail, the flow guide surface 313 on one side of the front tooth 310 in the length direction gradually inclines to the other side of the front tooth 310 in the length direction. And in the direction away from the rear tooth 320 in the thickness direction, the flow guide surface 313 on one side of the front tooth 310 in the length direction gradually inclines to the other side of the front tooth 310 in the length direction. In this way, liquid on the flow guide surface 313 above the front tooth 310 can flow down along the flow guide surface 313 in the direction away from the engagement area and away from the rear tooth 320, and under the guidance of the flow guide surface 313, the liquid flows down more quickly, effectively reducing the time of liquid staying in the engagement area, and further improving the waterproof effect of the waterproof zipper.
[0051] In one possible design, as shown in Figure 3As shown, the first front engagement surface 311 gradually inclines toward the side close to the second front engagement surface 312 in the direction from the first tail portion to the first head portion. In this arrangement, the first front engagement surface 311 is inclined relative to the length direction, and when the first front engagement surface 311 is on the side above the front tooth portion 310, liquid can flow down along the first front engagement surface 311 to reduce the possibility of water accumulation between the two front tooth portions 310 that are engaged with each other. Alternatively, the second front engagement surface 312 gradually inclines toward the side close to the first front engagement surface 311. In this arrangement, the second front engagement surface 312 is inclined relative to the length direction, and when the second front engagement surface 312 is on the side above the front tooth portion 310, liquid can flow down along the second front engagement surface 312 to also reduce the possibility of water accumulation between the two front tooth portions 310 that are engaged with each other. Alternatively, as shown in FIG. 2, the first front engagement surface 311 gradually inclines toward the side close to the second front engagement surface 312 in the direction from the first tail portion to the first head portion, and the second front engagement surface 312 gradually inclines toward the side close to the first front engagement surface 311. In this arrangement, no matter whether the first front engagement surface 311 is on the side above the front tooth portion 310 or the second front engagement surface 312 is on the side above the front tooth portion 310, the possibility of water accumulation between the two front tooth portions 310 that are engaged with each other can be reduced. Figure 5 As shown, the first front engagement surface 311 gradually inclines toward the side close to the second front engagement surface 312 in the direction from the first tail portion to the first head portion, and the second front engagement surface 312 gradually inclines toward the side close to the first front engagement surface 311. In this arrangement, no matter whether the first front engagement surface 311 is on the side above the front tooth portion 310 or the second front engagement surface 312 is on the side above the front tooth portion 310, the possibility of water accumulation between the two front tooth portions 310 that are engaged with each other can be reduced.
[0052] For ease of description, the side of the first head portion with the first front engagement surface 311 is referred to as the first side in the length direction, and the side of the first head portion with the second front engagement surface 312 is referred to as the second side in the length direction. In some embodiments, the first tail portion is provided with a flow guide surface 313 on the first side in the length direction. For ease of description, the flow guide surface 313 on the first side of the first tail portion in the length direction is referred to as the first flow guide surface. In the direction from the first head portion to the first tail portion, the first flow guide surface gradually inclines toward the second side of the front tooth portion 310 in the length direction. In the direction from the first tail portion to the first head portion, the first front engagement surface 311 gradually inclines toward the side close to the second front engagement surface 312. In this arrangement, the first front engagement surface 311 connects with the first flow guide surface, and the projection shape of the first front engagement surface 311 and the first flow guide surface on a projection plane perpendicular to the thickness direction is substantially a “person” shape. When the first side in the length direction is the upper side, the situation of water accumulation above the front tooth portion 310 can be effectively avoided, and the waterproof effect of the waterproof zipper is effectively improved.
[0053] In other embodiments, as shown in FIG. 3, the first front engagement surface 311 gradually inclines toward the side close to the second front engagement surface 312 in the direction from the first tail portion to the first head portion, and the second front engagement surface 312 gradually inclines toward the side close to the first front engagement surface 311. In this arrangement, no matter whether the first front engagement surface 311 is on the side above the front tooth portion 310 or the second front engagement surface 312 is on the side above the front tooth portion 310, the possibility of water accumulation between the two front tooth portions 310 that are engaged with each other can be reduced. Figure 3As shown, a guide surface 313 is provided on the second side of the first tail in the length direction. For ease of description, the guide surface 313 on the second side of the first tail in the length direction is referred to as the second guide surface. In the direction from the first head to the first tail, the second guide surface gradually tilts towards the first side of the front teeth 310 in the length direction. In the direction from the first tail to the first head, the second front engagement surface 312 gradually tilts towards the side closer to the first front engagement surface 311. In this arrangement, the second front engagement surface 312 connects with the second guide surface, so that the projection shape of the second front engagement surface 312 and the second guide surface on the projection plane perpendicular to the thickness direction is approximately "V" shaped. When the second side in the length direction is the upper side, it can also effectively prevent water from accumulating above the front teeth 310, thereby improving the waterproof effect of the waterproof zipper.
[0054] In one possible design, such as Figure 5 or Figure 6 As shown, the front teeth 310 are symmetrically arranged with respect to the reference plane, which passes through the middle of the front teeth 310 and is perpendicular to the length direction. Since the length direction of the waterproof zipper may change as the product moves in actual applications, this arrangement ensures good waterproofing regardless of whether the first or second side of the waterproof zipper's length direction is the top.
[0055] In one possible design, such as Figure 1 , Figure 2 , Figure 6 or Figure 7 As shown, the first toothed chain 100 and the second toothed chain 200 each include a waterproof strip 400. In the first toothed chain 100, the front tooth portion 310 and the rear tooth portion 320 of each meshing tooth 300 are respectively clamped on opposite sides of the waterproof strip 400. In the second toothed chain 200, the front tooth portion 310 and the rear tooth portion 320 of each meshing tooth 300 are respectively clamped on opposite sides of the waterproof strip 400. Specifically, in the first toothed chain 100, the front tooth portion 310 of each meshing tooth 300 is located on the first side of the waterproof strip 400 in the thickness direction, and the rear tooth portion 320 of each meshing tooth 300 is located on the second side of the waterproof strip 400 in the thickness direction. In practical applications, the first side in the thickness direction can be the outer side of the product, and the second side in the thickness direction can be the inner side of the product. The arrangement of the multiple meshing teeth 300 and the waterproof strip 400 in the second toothed chain 200 is the same as that in the first toothed chain 100, and will not be described again here. By incorporating a waterproof strip 400, the waterproof effect of the waterproof zipper can be improved. Optionally, the waterproof strip 400 includes a fabric strip and a waterproof membrane, the waterproof membrane covering at least a portion of the outer surface of the fabric strip to enable the waterproof strip 400 to function as a waterproof element.
