Description

Technical Field

[0001] This utility model relates to an anti-theft zipper for backpacks. Background Technology

[0002] In modern security management and anti-theft systems, zipper pulls, as an indispensable connecting component, are widely used in various equipment, doors, windows, cabinets, and other locations. However, with continuous technological advancements, traditional zipper pull designs have gradually revealed some significant security vulnerabilities, particularly in their anti-theft performance. Most existing zipper pulls rely on relatively simple slot or latch designs. These designs are easily affected by external forces or abnormal operations in practical applications, leading to easy disassembly or damage to the zipper pull. This significantly reduces the overall anti-theft effectiveness and fails to effectively guarantee equipment security.

[0003] Existing zipper pull designs typically employ simple slot and pin designs, which are susceptible to damage from external impacts or unauthorized operations during actual use. For example, the slot fixing method is relatively simple, lacking sufficient complexity and security, and can be easily disassembled by skilled personnel using specialized tools, leading to theft or serious security risks. This design deficiency significantly reduces the zipper pull's anti-theft performance, rendering it ineffective against external threats.

[0004] Furthermore, some traditional zipper pull connection methods may result in insecure connections in practical applications. With prolonged use and wear, the zipper pull may gradually loosen or detach, severely affecting the stability and safety of the overall structure. In high-frequency use environments, loosening of the zipper pull not only directly affects performance but may also lead to equipment damage, thereby increasing maintenance costs and repair difficulties.

[0005] Currently, many zipper pull designs lack necessary tamper-proof features, making them easy for criminals to quickly disassemble or damage, failing to effectively increase the difficulty and complexity of disassembly. This design flaw results in poor protection against external threats, severely impacting the device's security and durability, and failing to meet the needs of modern security management and anti-theft systems. Therefore, there is an urgent need to improve and optimize traditional zipper pull designs to enhance their security and anti-theft performance. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-theft zipper for backpacks that can improve the connection strength of the zipper, enhance its anti-theft and stability, and increase the difficulty of disassembly through an innovative bayonet structure to prevent unauthorized personnel from illegally disassembling and damaging it, thereby improving the overall security and protection of the device.

[0007] The technical solution adopted by this utility model to solve its technical problem is: An anti-theft zipper for a backpack includes a first zipper and a second zipper that are joined together on the left and right sides. The first zipper includes a first zipper base and a zipper handle disposed on the first zipper base. The second zipper includes a second zipper base and a zipper slot disposed on the second zipper base that engages with the zipper handle to form a fitting connection. The zipper handle has protruding latches on both sides. The inner side of the zipper slot has a curved latch. The curved latch includes an inclined entry section and a locking section that bends with the entry section.

[0008] Preferably, the first and second zipper heads have the same structure and are mirror-symmetrical.

[0009] Preferably, the pull head slot is composed of two spaced-apart clamps, and the curved latch is located on the inward side of the clamps.

[0010] Preferably, the entry section is a ramp section that slopes from the inside out, and the locking section is a vertical section that is connected to the entry section and is arranged vertically.

[0011] Preferably, the bottom of the locking section is provided with a through-plate, and the second pull head seat is provided with a clearance arrangement for the bottom of the locking section.

[0012] Preferably, the protruding clip is a cylindrical protrusion with a spherical convex surface, and the first pull head seat provides a clearance to the bottom of the protruding clip.

[0013] The beneficial effects of this utility model are as follows: This new anti-theft zipper design uses protruding latches on both sides of the zipper handle to engage with curved latches within the zipper's slot, creating a locking connection that prevents the zipper from being easily disassembled or damaged during normal use. In particular, the locking section of the curved latch features a bent design, which effectively prevents external force damage or improper disassembly, enhancing the anti-theft effect and reducing the risk of theft.

[0014] The interlocking connection between the zipper handle and the zipper slot not only ensures the stability of the zipper but also effectively avoids instability or malfunctions caused by loose connections in traditional structures. The precise fit between the protruding clip and the slot ensures that the zipper will not loosen due to friction or external forces during use, improving the overall robustness and durability of the structure.

[0015] The curved bayonet design of the entry and locking sections makes disassembly of the zipper pull more complex, making it less susceptible to disassembly or hacking by unauthorized personnel. In particular, the inclined design of the entry section makes disassembly more difficult for regular operators, while also preventing damage to the zipper pull due to misoperation, thus increasing the equipment's security and anti-theft capabilities.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Example See Figure 1-2 As shown, an anti-theft zipper for a backpack includes a first zipper 1 and a second zipper 2 connected from left to right. The first zipper 1 includes a first zipper base 11 and a zipper handle 12 disposed on the first zipper base 11. The second zipper 2 includes a second zipper base 21 and a zipper slot 22 disposed on the second zipper base 21, which cooperates with the zipper handle 12 to form an interlocking connection. The zipper handle 12 has protruding latches 13 on both sides. The inner side of the zipper slot 22 has a curved latch 23. The curved latch 23 includes an inclined entry section 231 and a locking section 232 that bends and engages with the entry section 231.

[0019] The protruding latches 13 on both sides of the zipper handle 12 fit tightly with the curved latches 23 inside the zipper slot 22, forming a robust mating connection. The curved latches 23 design increases the difficulty of disassembly, especially the bent design of its locking section 232 and entry section 231, making it difficult to disassemble with ordinary tools or illegal operations. This design effectively improves the anti-theft features of the zipper and prevents unauthorized disassembly and damage.

[0020] The interlocking connection of the zipper pull ensures its stability, and the precise fit between the protruding locking head 13 and the locking slot prevents the connection from loosening or falling off. Even under prolonged use or external force, the zipper pull remains firmly connected, reducing the risk of equipment damage or failure. This stability enhances the durability and long-term performance of the entire device.

[0021] While enhancing anti-theft capabilities, the design still prioritizes ease of use. The inclined entry section 231 of the curved bayonet 23 allows legitimate users to easily perform installation and disassembly operations, while making unauthorized disassembly extremely difficult. This ingenious design ensures anti-theft effectiveness without compromising normal use and maintenance, thus improving the overall user experience and ease of equipment management.

[0022] The first zipper seat 11 and the second zipper seat 21 have the same structure and are mirror symmetrical; the zipper slot 22 is composed of two spaced-apart clamps, and the curved slot 23 is located on the inner side of the clamps.

[0023] The first pull head 11 and the second pull head 21 have the same structure and are designed in a mirror-symmetric manner, which simplifies the production, assembly, and maintenance processes. This symmetrical structure reduces the variability of parts, facilitating mass production and standardized assembly. At the same time, during assembly, regardless of the position of the left and right parts, precise fit can be ensured, reducing the risk of assembly errors and improving assembly efficiency.

[0024] The zipper pull slot 22 consists of two spaced-apart clamping plates. The spacing between the plates not only enhances the structural stability of the slot but also allows it to withstand greater external forces. Because the clamping plates effectively distribute pressure and increase the overall strength of the slot, the zipper pull can better resist external impacts or forces during use, reducing the possibility of deformation or damage to the slot due to uneven stress.

[0025] The curved latch 23 is positioned on the inward side of the clamping plate, a design that ensures the anti-theft performance of the pull tab slot 22. Because the internal structure of the latch is relatively concealed, unauthorized personnel cannot easily access it during disassembly, increasing the difficulty of disassembly. This design avoids direct application of external tools to the latch, enhancing the anti-theft effect. In particular, the spacing between the clamping plates effectively limits the space and angle for unauthorized disassembly, further strengthening the anti-theft function.

[0026] The entry section 231 is a ramp section that slopes from the inside out. The locking section 232 is a vertical section that is connected to the entry section 231 and is arranged vertically. The bottom of the locking section 232 is provided with a through clamp, and the second pull head seat 21 is provided to avoid the bottom of the locking section 232. The protruding latch 13 is a cylindrical protrusion with a spherical convex surface, and the first pull head seat 11 is provided to avoid the bottom of the protruding latch 13.

[0027] The entry section 231 is an inwardly sloping ramp, while the locking section 232 is a vertical section with a through-plate at the bottom. The second pull head seat 21 is designed to avoid obstructing the bottom of the locking section 232. This design makes the connection between the latch and the locking head more complex, increasing the difficulty of disassembly. Unauthorized personnel must not only navigate the sloping entry section 231 of the slot but also avoid the vertical design of the locking section 232 during disassembly, further enhancing anti-theft and anti-tampering capabilities. It avoids common quick disassembly methods, improving overall security.

[0028] By cleverly avoiding direct contact or friction between the bottom of the protruding latch 13 and the first zipper holder 11, and between the bottom of the slot and the second zipper holder 21, the design ensures the stability of the zipper connection. The cylindrical spherical protruding latch 13 perfectly matches the curved latch 23 within the slot, reducing the risk of wear and loosening during connection. This precise fit guarantees the durability of the zipper and the strength of the connection during long-term use, ensuring that the connection is not easily loosened or damaged even in environments with high-frequency use.

[0029] This design not only enhances anti-theft and durability but also optimizes the assembly process through its avoidance design. The avoidance design between the latch and the slot prevents excessive friction or improper jamming, making the zipper pull smoother during installation and reducing assembly errors. Furthermore, the combination of the cylindrical spherical protrusion latch 13 and the slot also improves the smoothness of the zipper pull during normal use, reducing friction and resistance during operation, resulting in a better user experience and convenience.

[0030] To lock the lock, first grasp both the left and right sliders with both hands and pull them in opposite directions simultaneously, ensuring they are tightly closed. Once fully closed, gently press down on the right slider with your right hand to securely lock the mechanism. To unlock, first press down on the left slider with your left hand, then lift the right slider with your right hand. Once the right slider is fully lifted, pull in opposite directions with both hands to unlock the lock and return it to its initial position. Careful operation is required throughout the process to ensure each step is accurate and to guarantee the lock's proper function.
