[0052] The working principle of a safe anti-theft self-locking zipper structure of the utility model is specifically as follows:
[0053] The slider 1 plays a vital role. The tooth groove 9 at the bottom of the slider ensures precise fit with the zipper teeth, while the hidden lock cavity inside it becomes the core stage of the entire locking mechanism. The pull rod 2 is designed as a U-shaped structure, one end of which is hinged to the slider through the lock mouth 3 to form a movable joint, and the other end goes deep into the lock cavity inside the slider to interact directly with the locking component. The locking component, that is, the spring lock pin, consists of a spring member 6, a locking rod 4 and a pressing rod 5, and is the heart of the entire safety mechanism. The spring member provides the necessary elastic restoring force to ensure that the locking rod is in the locked position in the natural state. A limiting rod 7 is provided at the bottom of the lock groove 8 on the front side of the locking rod, which is precisely docked with the limiting hole 18 on the groove 17 of the pull rod in the lock cavity to achieve effective locking of the pull rod. This locking process is controlled by the pressing action of the pressing rod 5. The pressing rod is located at the top of the locking rod and is adapted to the opening at the top of the pull head. By pressing, the user can overcome the resistance of the spring member and separate the limiting rod of the locking rod from the limiting hole of the pull rod, thereby unlocking the pull rod and allowing it to move freely.
[0054] In order to further enhance the stability and security of the lock, the designer cleverly embedded a magnet 11 in the front half of the hinged end of the pull rod and the lock, using the magnetic effect to strengthen the physical connection between the pull rod and the lock, so that even if disturbed by external forces, the pull rod is not easy to escape from the locked state, greatly improving the anti-theft performance.
[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
