Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper pull technology, and in particular to a magnetic anti-theft zipper pull with a card hole. Background Technology
[0002] As people place increasing importance on the security of their personal belongings, especially during travel, outdoor activities, and daily life, anti-theft technology is becoming increasingly prevalent in various products. Zippers, as a fundamental component of clothing, bags, and other products, have also received widespread attention for their security. Traditional zipper pulls have simple designs that are easily pried open or accidentally opened, failing to meet modern consumers' dual demands for security and convenience. Furthermore, most existing anti-theft zipper pulls suffer from complex structures and are difficult to open.
[0003] Therefore, there is an urgent need for a magnetic anti-theft zipper pull with a card slot that combines anti-theft and easy opening. Utility Model Content
[0004] To solve the problem that existing zipper pulls cannot simultaneously achieve both anti-theft and easy-to-open functionality.
[0005] This utility model provides a magnetic anti-theft pull head with a locking hole, including a first pull head and a second pull head arranged opposite each other. The first pull head has a first pull nose, and the second pull head has a second pull nose. One side of the first pull nose has a first extension portion, and the first extension portion has a first groove. The first groove has a first magnetic snap inside, and the two sides of the first groove have a first protrusion and a first round hole, respectively. One side of the second pull nose has a second extension portion, and the second extension portion has a second groove. The second groove has a second magnetic snap that attracts the first magnetic snap inside, and the two sides of the second groove have a second protrusion that matches the first round hole and a second round hole that matches the first protrusion, respectively. When the first pull head and the second pull head are closed, the first magnetic snap and the second magnetic snap attract each other, the first protrusion is inserted into the second round hole, the second protrusion is inserted into the first round hole, and the first extension portion and the second extension portion are tightly fitted and locked together.
[0006] Preferably, the thickness of the first magnetic snap is less than or equal to the depth of the first groove, the thickness of the second magnetic snap is less than or equal to the depth of the second groove, and the depths of the first groove and the second groove are equal and both are 0.8mm~1.2mm.
[0007] Preferably, the thickness of the first magnetic snap, the thickness of the second magnetic snap, the depth of the first groove, and the depth of the second groove are all 1mm.
[0008] Preferably, both the first magnetic snap and the second magnetic snap are double-sided magnetic snaps.
[0009] Preferably, the height of the first protrusion is less than or equal to the depth of the first circular hole, the height of the second protrusion is less than or equal to the depth of the second circular hole, and the heights of the first and second protrusions are equal and both are 0.3mm to 0.7mm.
[0010] Preferably, the height of the first protrusion, the depth of the first circular hole, the height of the second protrusion, and the depth of the second circular hole are all 0.5 mm.
[0011] Preferably, both the first and second protrusions are hemispherical structures.
[0012] The beneficial effects of this invention are reflected in the fact that when the first and second zipper pulls are closed, they are not only connected by the attraction between the first and second magnetic snaps, but also further enhanced by a mechanical locking mechanism where the first latch is embedded in the second round hole and the second latch is embedded in the first round hole, preventing accidental opening. Since the first and second magnetic snaps, the first latch, the first round hole, the second latch, and the second round hole are all hidden between the first and second zipper pulls, they are difficult for thieves to find, thus increasing the difficulty of theft. Even if an attempt is made to open them, considerable force is required, and the user can feel a noticeable "click" sound or vibration feedback. When the user separates the first and second zipper pulls themselves, a simple pulling operation is all that's needed. This solves the problem that existing zipper pulls cannot simultaneously achieve both anti-theft and easy-to-open properties. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0018] Reference Figures 1-3 A magnetic anti-theft zipper with a latch includes a first zipper 1 and a second zipper 2 facing each other. The first zipper 1 has a first zipper nose 11, and the second zipper 2 has a second zipper nose 21. The first zipper nose 11 has a first extension 12 on one side, and the first extension 12 has a first groove 13. The first groove 13 has a first magnetic snap 14 inside, and the first groove 13 has a first latching protrusion 15 and a first round hole 16 on both sides. The second zipper nose 21 has a second extension 22 on one side, and the second extension 22 has a second groove. 23. The interior of the second groove 23 is provided with a second magnetic snap 24 that attracts the first magnetic snap 14. The two sides of the second groove 23 are respectively provided with a second latch 25 that matches the first round hole 16 and a second round hole 26 that matches the first latch 15. When the first pull head 1 and the second pull head 2 are closed, the first magnetic snap 14 and the second magnetic snap 24 attract each other, the first latch 15 is inserted into the second round hole 26, the second latch 25 is inserted into the first round hole 16, and the first extension part 12 and the second extension part 22 are tightly fitted and locked together.
[0019] When the first zipper pull 1 and the second zipper pull 2 are closed, they are connected not only by the attraction between the first magnetic snap 14 and the second magnetic snap 24, but also by a mechanical locking mechanism where the first latch 15 is embedded in the second round hole 26 and the second latch 25 is embedded in the first round hole 16, further enhancing the stability of the connection and preventing accidental opening. Since the first magnetic snap 14, the second magnetic snap 24, the first latch 15, the first round hole 16, the second latch 25, and the second round hole 26 are all hidden between the first zipper pull 1 and the second zipper pull 2, they are difficult for thieves to find, thus increasing the difficulty of theft. Even if an attempt is made to open them, considerable force is required, and the user can feel a noticeable "click" sound or vibration feedback. When the user separates the first zipper pull 1 and the second zipper pull 2, a simple pulling operation is all that's needed. This solves the problem that existing zipper pulls cannot simultaneously achieve both anti-theft and easy-to-open functionality.
[0020] In some embodiments, the thickness of the first magnetic snap 14 is less than or equal to the depth of the first groove 13, the thickness of the second magnetic snap 24 is less than or equal to the depth of the second groove 23, and the depths of the first groove 13 and the second groove 23 are equal and both are 0.8mm to 1.2mm.
[0021] Because the thickness of the first magnetic snap 14 is less than or equal to the depth of the first groove 13, and the thickness of the second magnetic snap 24 is less than or equal to the depth of the second groove 23, the first magnetic snap 14 is completely embedded in the first groove 13, and the second magnetic snap 24 is also completely embedded in the second groove 23, thereby reducing wear on the first magnetic snap 14 and the second magnetic snap 24. Furthermore, when the first pull tab 1 and the second pull tab 2 are closed, it ensures that the first extension portion 12 and the second extension portion 22 can fit tightly together, preventing uneven surfaces and difficulty in closing due to the protrusion of the first magnetic snap 14 or the second magnetic snap 24, and also improving aesthetics.
[0022] The first groove 13 and the second groove 23 are set with a depth of 0.8mm to 1.2mm, which ensures that there is enough space to accommodate the first magnetic buckle 14 and the second magnetic buckle 24, ensuring the magnetic attraction effect, while not affecting the mechanical strength of the first extension part 12 and the second extension part 22 themselves.
[0023] Preferably, the thickness of the first magnetic snap 14, the thickness of the second magnetic snap 24, the depth of the first groove 13, and the depth of the second groove 23 are all 1mm.
[0024] The uniform 1mm thickness and depth were determined through multiple tests. This ensures the magnetic attraction effect without compromising the mechanical strength of the first extension part 12 and the second extension part 22. It avoids wasting space due to the first magnetic buckle 14 or the second magnetic buckle 24 being too thick, or having insufficient attraction force due to the first magnetic buckle 14 or the second magnetic buckle being too thin. In addition, it simplifies the manufacturing process and reduces production difficulty and cost.
[0025] In some embodiments, both the first magnetic snap 14 and the second magnetic snap 24 are double-sided magnetic snaps.
[0026] Double-sided magnetic snap fasteners mean that both sides of each magnetic snap fastener are magnetic, which facilitates the installation of the first magnetic snap fastener 14 and the second magnetic snap fastener 24. Regardless of whether either side of the first magnetic snap fastener 14 faces the outside of the first groove 13, or regardless of whether either side of the second magnetic snap fastener 24 faces the outside of the second groove 23, the first magnetic snap fastener 14 and the second magnetic snap fastener 24 can attract each other.
[0027] In some embodiments, the height of the first protrusion 15 is less than or equal to the depth of the first circular hole 16, the height of the second protrusion 25 is less than or equal to the depth of the second circular hole 26, and the heights of the first protrusion 15 and the second protrusion 25 are equal and both are 0.3mm to 0.7mm.
[0028] Because the height of the first latch 15 is less than or equal to the depth of the first circular hole 16, and the height of the second latch 25 is less than or equal to the depth of the second circular hole 26, it is ensured that the first slider 1 and the second slider 2 can fit tightly and lock together each time they are closed. The height of the first latch 15 and the second latch 25 is set in the range of 0.3mm to 0.7mm, which ensures sufficient locking strength without causing the user to feel strained during operation, thus improving the user experience.
[0029] Preferably, the height of the first protrusion 15, the depth of the first circular hole 16, the height of the second protrusion 25, and the depth of the second circular hole 26 are all 0.5 mm.
[0030] The height of the first latch 15 and the second latch 25 are consistent with the depth of the first round hole 16 and the second round hole 26, both being 0.5mm. This ensures that when the first slider 1 and the second slider 2 are closed, the first latch 15 and the first round hole 16, as well as the second latch 25 and the second round hole 26, are tightly fitted together, and the first extension part 12 and the second extension part 22 are tightly attached.
[0031] In some embodiments, both the first protrusion 15 and the second protrusion 25 are hemispherical structures.
[0032] The hemispherical structure has a smooth surface without sharp edges, allowing the first locking protrusion 15 to slide more smoothly into the first circular hole 16, or the second locking protrusion 25 to slide more smoothly into the second circular hole 26, reducing friction. Compared to square or other shaped locking protrusions, the hemispherical design significantly reduces insertion resistance.
[0033] In the description of the embodiments of this utility model, it should be understood that "~" represents a range of two values, and this range includes the endpoints. For example, "AB" represents a range greater than or equal to A and less than or equal to B.
[0034] In the description of embodiments of this utility model, 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
