Description

Technical Field

[0001] The utility model relates to a zipper, in particular to an interlocking double-track zipper. Background Art

[0002] A customs lock (also known as a customs seal, lead seal, or security seal) is a device used to ensure the safety and integrity of goods during transportation. It is usually installed by customs or other authorized agencies before goods are exported to prove that the goods have not been illegally opened or tampered with during their journey from departure to destination.

[0003] While existing double-track zippers suitable for customs locks have improved sealing and safety to a certain extent, they still have some shortcomings, such as the lack of an effective linkage mechanism between the two sliders, which can easily cause misalignment or separation, affecting the user experience. Therefore, in response to the above situation, there is an urgent need to develop an interlocking double-track zipper to overcome the current shortcomings in practical applications. Utility Model Content

[0004] The purpose of the present invention is to provide an interlocking double-track zipper, aiming to solve the problems mentioned in the above background technology.

[0005] The utility model is implemented as follows: an interlocking double-track zipper includes a first slider and a second slider, wherein the first slider and the second slider are respectively fixed with a first slider lock and a second slider lock, and further includes:

[0006] Pull tab 1 and pull tab 2, one end of each of the pull tabs 1 and pull tab 2 is movably connected to the slider lock 1 and slider lock 2 respectively; each of the pull tabs 1 and pull tab 2 is provided with an interlocking groove 1 and an interlocking groove 2 that cooperate with each other, and each of the interlocking groove 1 and the interlocking groove 2 is also provided with a lock column and a lock hole that can cooperate with each other for plugging and locking; when the interlocking groove 1 and the interlocking groove 2 of the pull tab 1 and the pull tab 2 and the lock column and the lock hole thereon are cooperated and connected, the pull tab 1 and the pull tab 2 are combined into a whole.

[0007] According to a further technical solution, one end of the pull tab 1 and the pull tab 2 are respectively provided with a connecting hole 1 and a connecting hole 2, and the slider lock 1 and the slider lock 2 are respectively movably connected to the connecting hole 1 and the connecting hole 2.

[0008] According to a further technical solution, a U-shaped lock buckle 1 and a U-shaped lock buckle 2 are fixed to the back ends of the pull tab 1 and the pull tab 2 away from the connecting hole 1 and the connecting hole 2 respectively.

[0009] According to a further technical solution, the interlocking groove 1 is provided on one side of the pull tab 1, and the interlocking groove 2 is provided on the other side of the pull tab 2.

[0010] A further technical solution is that a lock hole is formed on the interlocking groove 1 and the interlocking groove 2, and a lock column that can be plugged and locked with the lock hole is fixed on the interlocking groove 1 and the interlocking groove 2 respectively.

[0011] The utility model provides an interlocking double-track zipper with the following beneficial effects:

[0012] The interlocking grooves 1 and 2 on pull tabs 1 and 2, along with the locking post and keyhole, ensure that the two pull tabs will not easily separate when closed, enhancing the zipper's safety and making it more versatile. Despite the inclusion of an additional interlocking mechanism, the overall design is simple, making it easy to manufacture and maintain. Furthermore, the coordinated use of the locking post and keyhole ensures a reliable locking effect. BRIEF DESCRIPTION OF THE DRAWINGS
