[0046] Zippers are very common items in daily life, widely used on clothing, luggage, and other products. A zipper consists of a slider and two cloth strips with chain elements. The slider consists of a base and a pull tab. The pull tab drives the base to move, allowing the chain elements on the two strips to engage and disengage. To facilitate user use, some clothing or luggage sliders include two bases. When the two bases are brought together, the chain elements on the two strips engage. However, with existing zippers, when the two bases are brought together, rainwater easily enters the clothing or luggage, resulting in a poor user experience.

[0047] The following is a preferred embodiment of a waterproof zipper provided by the present invention that can solve the above technical problems.

[0048] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a waterproof zipper, which includes a waterproof base assembly 1 and two cloth tapes 2.

[0049] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The waterproof base assembly 1 includes a female base 11 and a male base 12, both of which can be arranged along a first direction ( Figure 3 The mother base 11 includes a mother top sheet 111, a mother bottom sheet 112 and a mother separation column 113. The mother top sheet 111 and the mother bottom sheet 112 are separated and connected along the second direction ( Figure 3The male base 12 comprises a male top piece 121, a male bottom piece 122 and a male separation column 123. The male top piece 121 and the male bottom piece 122 are arranged along the second direction, and the two are parallel to each other and spaced apart. The male separation column 123 is connected between the male top piece 121 and the male bottom piece 122. One end of the male bottom piece 122 is provided with a slot 1121, and the slot 1121 has an insertion port 11211 facing the male base 12. The male base 12 includes a male top piece 121, a male bottom piece 122 and a male separation column 123. The male top piece 121 and the male bottom piece 122 are arranged along the second direction, and the two are parallel to each other and spaced apart. The male separation column 123 is connected between the male top piece 121 and the male bottom piece 122. One end of the male bottom piece 122 is provided with an insertion block 1221 protruding toward the female base 11. Among them, when the female base 11 and the male base 12 are connected, the plug block 1221 is inserted into the slot 1121 from the insertion port 11211, and the female bottom film 112 and the male bottom film 122 are fitted together in the first direction so that the connection position of the two covers the chain tooth 21 between the female separation column 113 and the male separation column 123.

[0050] Please refer to Figure 1 and Figure 2 The edges of both fabric strips 2 are provided with fasteners 21. The fasteners 21 of the two fabric strips 2 are disposed between the female top sheet 111 and the female bottom sheet 112, and between the male top sheet 121 and the male bottom sheet 122. At the female separation post 113, the fasteners 21 of the two fabric strips 2 are located on either side of the female separation post 113. At the male separation post 123, the fasteners 21 of the two fabric strips 2 are located on either side of the male separation post 123.

[0051] When in use, the waterproof base assembly 1 and waterproof zipper of the present invention locate the link elements 21 on the two fabric strips 2 between the female top sheet 111 and the female bottom sheet 112, and between the male top sheet 121 and the male bottom sheet 122. At the female separation post 113, the link elements 21 on the two fabric strips 2 are located on either side of the female separation post 113. At the male separation post 123, the link elements 21 on the two fabric strips 2 are located on either side of the male separation post 123. When the female base 11 and the male base 12 are separated, the link elements 21 on the two fabric strips 2 separate. When the female base 11 and the male base 12 are connected, the link elements 21 on the two fabric strips 2 engage. At this point, there is inevitably a gap between the link elements 21 of the two fabric strips 2 between the female separation post 113 and the male separation post 123. The male base 12 and the female base 11 fit together to shield the two link elements 21 and the gap between them, preventing rainwater from entering clothing or bags, effectively improving the user experience. The plug block 1221 is plugged into the slot 1121 to ensure that the male base 12 and the female base 11 are reliably connected and not easily separated, thereby effectively preventing water from entering.

[0052] Please refer to Figure 5, slot 1121 penetrates the two side surfaces of the female base 112 in the second direction. When the female base 11 and the male base 12 are connected, the insert 1221 is interference fit in the slot 1121, and the three side surfaces of the insert 1221 respectively fit the three walls of the slot 1121. The above structure facilitates the processing of the slot 1121 on the female base 112, and makes the two opposing side walls of the slot 1121 larger in the second direction, which facilitates the processing of the slot 1121. The friction between the two opposing side walls of the slot 1121 and the two corresponding side surfaces of the insert 1221 is greater, making it difficult for the insert 1221 to fall out of the slot 1121, thereby effectively preventing water from entering. In other embodiments, the slot 1121 may not penetrate both side surfaces of the female base 112 in the second direction; alternatively, the slot 1121 may only penetrate one of the side surfaces of the female base 112 in the second direction.

[0053] Please refer to Figure 5 and Figure 6 The insert block 1221 is in the shape of a square column, with its axis parallel to the first direction, and the slot 1121 is in the shape of a square that matches the insert block 1221. The above structure is convenient for processing and manufacturing of the product.

[0054] In other embodiments, the insert block 1221 may be trapezoidal, with the side of the insert block 1221 close to the mother base 11 being the short bottom side of the insert block 1221, and the shape of the slot 1121 matching the insert block 1221. With the above structure, the insert block 1221 is easily inserted into the slot 1121.

[0055] Please refer to Figure 5 and Figure 6 The thickness of the female bottom sheet 112 is greater than that of the female top sheet 111. The thickness of the male bottom sheet 122 is greater than that of the male top sheet 121. The dimension of the insert 1221 in the second direction is equal to the thickness of the male bottom sheet 122. This structure increases the dimensions of the slot 1121 and the insert 1221 in the second direction. Without significant external force, the insert 1221 is unlikely to disengage from the slot 1121, thus preventing water from entering and improving waterproof performance.

[0056] Please continue to refer to Figure 3 、 Figure 5 and Figure 6 The slot 1121 is located on the side of the female separation column 113 close to the male base 12, and the slot 1121 is located on the female base 11 in the third direction ( Figure 3The third direction is perpendicular to the first and second directions. The insert block 1221 is located in the middle of the male base 12 in the third direction, and the male separation post 123 is positioned on the edge of the insert block 1221 near the female base 11. This structure minimizes the gap between the fastener elements 21 of the two fabric tapes 2 when the female and male bases 11 and 12 are connected, preventing water from entering and improving waterproof performance.

[0057] Please continue to refer to Figure 5 and Figure 6 A female abutting piece 1111 is provided at one end of the female top piece 111 near the male base 12, and a male abutting piece 1211 is provided at one end of the male top piece 121 near the female base 11. When the insert 1221 is mated with the slot 1121, the female abutting piece 1111 and the male abutting piece 1211 abut against each other along a first direction. It is difficult to observe from below whether the insert 1221 and the slot 1121 are properly mated. When the female abutting piece 1111 and the male abutting piece 1211 located above abut against each other, it can be determined that the insert 1221 and the slot 1121 are properly mated, thereby effectively preventing water ingress and improving waterproof performance.

[0058] One end of the female separation column 113 is connected to the female abutment piece 1111. The female abutment piece 1111 is rectangular, with its length oriented in the third direction, which is perpendicular to the first and second directions. One end of the male separation column 123 is connected to the male abutment piece 1211. The male abutment piece 1211 is rectangular, with its length oriented in the third direction. The above structure allows the female abutment piece 1111 and the male abutment piece 1211 to be larger in the third direction, thereby covering the gap between the teeth 21 of the two cloth tapes 2 located between the female separation column 113 and the male separation column 123 from the outside of the teeth 2, effectively preventing water ingress and improving waterproof performance.

[0059] Please refer to Figure 5 , please combine Figure 3 Both sides of the mother bottom sheet 112 in the third direction are provided with limiting strips 1122 protruding toward the mother top sheet 111. The two limiting strips 1122 extend to either side of the slot 1121 in the third direction, which is perpendicular to the first and second directions. The limiting strips 1122 on either side of the slot 1121 can be used to gather the link elements 21 of the two fabric strips 2 at the junction of the insert 1221 and the slot 1121, reducing the gap between the link elements 21 of the two fabric strips 2, thereby preventing water from entering and improving the waterproof performance.

[0060] The working principle of the waterproof zipper of the preferred embodiment of the utility model:

[0061] When the female base 11 and male base 12 are separated, the chain elements 21 on the two fabric strips 2 separate. When the female base 11 and male base 12 are connected, the chain elements 21 on the two fabric strips 2 engage. At this point, the side of the male base 12 fits in place with the side of the female base 11, the insert 1221 is inserted into the slot 1121, and the female abutment piece 1111 abuts the male abutment piece 1211. At the junction of the insert 1221 and the slot 1121, the chain elements 21 on the two fabric strips 2 are gathered between the two limiting strips 1122, preventing water from entering and effectively improving the waterproof performance.

[0062] This completes the working principle of the waterproof zipper of this preferred embodiment.

[0063] When the waterproof base assembly and waterproof zipper of the utility model are in use, the chain teeth on the two cloth tapes are located between the female top plate and the female bottom plate, and between the male top plate and the male bottom plate. At the female separation column, the chain teeth on the two cloth tapes are respectively located on both sides of the female separation column. At the male separation column, the chain teeth on the two cloth tapes are respectively located on both sides of the male separation column. When the female base and the male base are separated, the chain teeth on the two cloth tapes are separated. When the female base and the male base are connected, the chain teeth on the two cloth tapes are engaged. At this time, there must be a gap between the chain teeth of the two cloth tapes between the female separation column and the male separation column. By fitting the male base and the female base, the two chain teeth and the gap between them can be blocked, which can prevent rainwater from entering clothes or bags, and effectively improve the user experience. The plug is inserted into the slot to make the male base and the female base reliably connected and not easy to separate, thereby effectively waterproofing.

[0064] To sum up, although the present invention has been disclosed as above in terms of preferred embodiments, the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes based on the concept of the technical solution of the present invention, should be covered by the scope of protection of the present invention.
