[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] Bags and luggage usually have two zipper pulls, and the pull tabs of each zipper pull are very easy to pull, which poses a risk of theft.
[0028] The following is a preferred embodiment of an anti-theft zipper and warning pull tab provided by this utility model, which can solve the above technical problems.
[0029] A preferred embodiment of this utility model provides a zipper. Please refer to... Figure 1The anti-theft zipper includes two fabric strips (not shown in the figure), two bases 12 and warning pull tabs. The inner edges of the two fabric strips are provided with teeth, and the two sub-pull tabs 11 are respectively connected to the two bases 12 so that the teeth of the two fabric strips can be separated and closed.
[0030] Please refer to Figure 1 and Figure 2 The warning pull tab includes two detachable sub-pull tabs 11 (only one is shown in the figure). The two sub-pull tabs 11 are connected to two bases 12 by ropes 114 respectively. The sub-pull tabs 11 are equipped with adsorption devices 111. When the two sub-pull tabs 11 are subjected to force, they can be attached and adsorbed or separated by adsorption devices 111.
[0031] The adsorption device 111 is a suction cup made of soft rubber material, such as soft TPU or silicone. The adsorption device 111 has a bowl-shaped or dome-shaped structure with a wall thickness of 1-1.5mm and smooth arc-shaped edges. When the adsorption devices of the two pull tabs are pressed together face to face, the internal air can be discharged to form a negative pressure vacuum state, so that the two pull tabs are firmly adsorbed. When peeling, a crisp "pop" sound is produced because air quickly enters the negative pressure area.
[0032] The rope 114 is made of high-strength nylon or polyester rope, which is flexible and ensures that the pull tab 11 can move freely and withstand tension.
[0033] The warning pull tab and zipper of this utility model, when the bag needs to be closed, the adsorption devices 111 of the two sub-pull tabs 11 are placed face to face, the air inside the adsorption device 111 is expelled, forming a negative pressure vacuum environment. Under the action of atmospheric pressure, the two sub-pull tabs 11 are tightly attracted together, accompanied by a "pop" sound, indicating that the closure is in place; when the bag needs to be opened or a thief attempts to illegally open it, external force is applied to peel off the adsorption device 111. At this time, air quickly enters the negative pressure area, producing a clear "snap" sound, forming an anti-theft warning.
[0034] Please refer to Figure 1 and Figure 2 The pull tab 11 includes a first connecting block 112, which is connected to a rope 114. The other end of the rope 114 is connected to an injection-molded part. The adsorption device 111 is detachably connected to the first connecting block 112. With the above structure, if the adsorption device 111 ages in the external environment, the adsorption device 111 can be replaced separately, saving costs.
[0035] Please refer to Figure 3 and Figure 4 Please also refer to Figure 1 and Figure 2A first engaging groove 1121 is provided on the periphery of the first connecting block 112, connecting the opposite two sides and the end face of the first connecting block 112. A second connecting block 113 is fixedly connected to the adsorption device 111. The second connecting block 113 is U-shaped and matches the shape of the first engaging groove 1121, and is interference-fitted into the first engaging groove 1121. The first connecting block 112 and the second connecting block 113 are made of rigid plastic. This structure ensures a secure connection between the first connecting block 112 and the second connecting block 113.
[0036] Please refer to Figure 1 The periphery of the second connecting block 113 is flush with the periphery of the first connecting block 112, which can distinguish whether the second connecting block 113 and the first connecting block 112 are properly engaged, and prevent external objects from scratching the second connecting block 113 and causing them to separate.
[0037] Please refer to Figure 3 and Figure 4 On the side of the first connecting block 112, a recess 1122 is provided at the bottom of the first snap-fit groove 1121. A protrusion 1131 is provided on the inner side of the support arm of the second connecting block 113, and the protrusion 1131 is located in the recess 1122. With the above structure, the second connecting block 113 can be prevented from detaching from the first connecting block 112 at will.
[0038] Please refer to Figure 3 and Figure 4 Multiple concave points 1122 are provided, and the multiple concave points 1122 are arranged along the insertion direction of the first connecting block 112 and the second connecting block 113. Multiple protrusions 1131 are provided corresponding to the multiple concave points 1122, which can make the connection between the first connecting block 112 and the second connecting block 113 more stable.
[0039] Please refer to Figure 3 and Figure 4 Multiple concave points 1122 gradually decrease in size along the pull-out direction of the second connecting block 113, and the size of each protrusion 1131 matches the corresponding concave point 1122. When replacing the adsorption device 111, the second connecting block 113 and the first connecting block 112 are forcefully pulled away from each other. After each protrusion 1131 is disengaged from the corresponding concave point 1122, due to the size mismatch, each protrusion 1131 will no longer engage with other concave points 1122, making it easy to separate the second connecting block 113 and the first connecting block 112.
[0040] Please refer to Figure 3 and Figure 4The surface of the first connecting block 112 is also provided with a second snap-fit groove 1123, which connects the end face of the first connecting block 112 and the first snap-fit groove 1121. The surface of the second connecting block 113 is also provided with a protrusion 1132, which is interference-fitted into the second snap-fit groove 1123. With the above structure, the connection between the first connecting block 112 and the second connecting block 113 can be made more secure.
[0041] Please refer to Figure 2 and Figure 4 The adsorption device 111 is fixedly connected to the surface of the protrusion 1132, and the adsorption direction of the two adsorption devices 111 is perpendicular to the insertion direction of the first connecting block 112 and the second connecting block 113. With the above structure, the second connecting block 113 will not be pulled out when separating the two adsorption devices 111.
[0042] The method for replacing the warning pull tab adsorption device 111 according to a preferred embodiment of this utility model: By disengaging the second connecting block 113 from the first latching slot 1121 and the protrusion 1132 from the second latching slot 1123, the first connecting block 112 and the second connecting block 113 can be separated for replacement of the adsorption device 111. Alternatively, by inserting the second connecting block 113 into the first latching slot 1121 and the protrusion 1132 into the second latching slot 1123, the first connecting block 112 and the second connecting block 113 can be connected together.
[0043] This is the method for replacing the warning pull tab with the adsorption device 111 in this preferred embodiment.
[0044] This invention relates to a warning pull tab and zipper. When the bag needs to be closed, the two pull tabs are positioned face to face, expelling the air inside and creating a negative pressure vacuum environment. Under atmospheric pressure, the two pull tabs tightly adhere, accompanied by a "pop" sound, indicating that the bag is fully closed. When the bag needs to be opened or a thief attempts to illegally open it, external force must be applied to detach the adsorption device. At this time, air quickly enters the negative pressure zone, producing a distinct "snap" sound, thus serving as an anti-theft warning.
[0045] This invention provides a post-assembly solution for pull tabs, which aims to give the product higher maintainability, customizability and production flexibility without sacrificing connection reliability.
[0046] When consumers encounter problems with the adsorption device due to prolonged sun exposure, physical wear and tear, or simply want to change the color or style, they can easily pry off the old adsorption device and press it into the new one by hand without tools. This greatly extends the overall lifespan of the product, reduces user costs, and aligns with sustainable design principles.
[0047] To reduce losses and logistics costs, the soft adsorption device is less likely to scratch and damage other parts during transportation, and can also avoid the scrapping of the entire sheet due to defects in individual parts, resulting in lower overall costs.
[0048] Brands can sell "absorption device replacement packs" with various colors, patterns, and even different materials (such as glow-in-the-dark or aromatherapy) separately, providing users with personalized fashion accessories and opening up new marketing models and profit growth points.
[0049] Through precise interference fit and the locking design of ring buckle-slot, the adsorption device will never fall off accidentally during normal use, and its connection strength far exceeds functional requirements.
[0050] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
