Its core structure consists of two rows of interlocking teeth, a sliding slider, and a fabric strap that supports the teeth. By pulling the slider, the two rows of teeth can be precisely engaged or disengaged, thus enabling items to be opened or closed quickly and securely.
[0003] Most handbags and backpacks on the market use zippers to open and close. Therefore, simply pulling the zipper pull can easily open the bag and expose the contents inside. The security is generally poor. If the bag owner is not paying attention or is away from home, it is easy for the contents inside the bag to be stolen. Utility Model Content
[0004] The purpose of this invention is to provide a zipper pull with anti-theft function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper pull with anti-theft function, comprising a zipper pull and a pull tab located at the rear of the zipper pull.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] like Figure 1-5As shown, this utility model discloses a zipper pull with anti-theft function, including a zipper pull 1, a pull tab 2 located on the rear side of the zipper pull 1, and an anti-theft component on the zipper pull 1. The anti-theft component includes a mounting box 3 fixedly mounted on the zipper pull 1, horizontal plates A4 and B5 fixedly mounted inside the mounting box 3, pressure strips A6 and B7 located inside the mounting box 3, a sliding post A8 fixedly mounted in front of the pressure strip A6, a sliding post B9 fixedly mounted behind the pressure strip B7, springs A10 and B11 respectively sleeved on the sliding posts A8 and B9, a top plate 12, and an insert frame 13 fixedly mounted below the top plate 12. The pull tab 2 is connected to the top plate 12, and the horizontal plate A4 is located in front of the horizontal plate B5. Strip A6 is located in front of pressure strip B7. Pressure strip A6 and pressure strip B7 are located between horizontal plate A4 and horizontal plate B5. Horizontal plate A4 and horizontal plate B5 are respectively provided with sliding holes A14 and B15. Sliding pins A8 and B9 are inserted into sliding holes A14 and B15 respectively and are slidably connected to horizontal plate A4 and horizontal plate B5. The front and rear ends of spring A10 are fixedly connected to horizontal plate A4 and pressure strip A6 respectively. The front and rear ends of spring B11 are fixedly connected to pressure strip B7 and horizontal plate B5 respectively. A through groove 16 is provided on the top wall of the mounting box 3 between pressure strip A6 and pressure strip B7. After inserting the frame 13 into the through groove 16, it is located inside the mounting box 3 and outside pressure strip A6 and pressure strip B7.In use, the mounting box 3 is placed above the pull head 1 and fixedly connected to the pull head 1 with screws, which facilitates disassembly and assembly. Since the front and rear ends of spring A10 are fixedly connected to the horizontal plate A4 and pressure strip A6 respectively, and the front and rear ends of spring B11 are fixedly connected to the pressure strip B7 and horizontal plate B5 respectively, springs A10 and B11 will push pressure strips A6 and B7 respectively, causing them to move closer to each other, so that pressure strip A6 and pressure strip B7 come into contact and connect, allowing the insertion frame 13 to be inserted into the through slot 1. 6. Since the through groove 16 is located between the pressure strips A6 and B7, the insert frame 13 will squeeze the pressure strips A6 and B7, causing them to move away from each other. After the insert frame 13 is fully inserted, it will be located inside the mounting box 3 and outside the pressure strips A6 and B7. The pressure strips A6 and B7 will be pushed back by the springs A10 and B11 and inserted into the middle of the insert frame 13, abutting against each other and fixing the insert frame 13 inside the mounting box 3, thus fixing the top plate 12. Since the pull tab 2 is connected to the top plate 12... At this time, pulling the pull tab 2 will normally move the zipper head 1, allowing the zipper to open and close. When the bag is not with the owner (for example, when eating or going to the restroom, the bag is placed on the seat), or when the bag is carried on the back and does not need to be opened frequently, pulling the vertical plate 17 vertically upwards will move the top plate 12 upwards. The insert frame 13 will push aside the pressure strips A6 and B7 and move upwards, allowing the insert frame 13 to be removed from the mounting box 3. At this time, the pull tab 2 separates from the zipper head 1, and the zipper head 1 cannot be easily pulled, thus providing an anti-theft function. Pulling the zipper pull 1 only engages the edge of the zipper pull 1. Since the mounting box 3 is fixedly equipped with several sharp rivets 24 on all four sides, when someone tries to pull the zipper pull 1, the sharp rivets 24 will prick their fingers, causing them to release their grip in pain, thus further enhancing the anti-theft function. In summary, this utility model has an anti-theft function, solving the problem that pulling the zipper pull can easily open the bag and expose the contents inside, which is generally not very secure. If the bag owner is not paying attention or is away from home, the contents inside the bag can easily be stolen.
[0021] Preferably, a vertical plate 17 is fixedly installed above the top plate 12, and a ring A18 is fixedly installed above the vertical plate 17. A ring B19 is fixedly installed on the front side of the pull tab 2. The rings A18 and B19 are interlocked. The rear side wall of the pressure strip A6, the front side wall of the pressure strip B7, and the bottom rod of the insert frame 13 are all arc-shaped. Because the rings A18 and B19 are interlocked, it facilitates the pull tab 2 to be pulled from any direction. Because the rear side wall of the pressure strip A6, the front side wall of the pressure strip B7, and the bottom rod of the insert frame 13 are all arc-shaped, it facilitates the insert frame 13 to push open the pressure strips A6 and B7 for movement.
[0022] Preferably, mounting rings A20 are fixedly installed on both the left and right sides of the mounting box 3, and screw holes matching the mounting rings A20 are opened on the top wall of the pull head 1. The mounting rings A20 are fixedly connected to the pull head 1 by screws. Mounting rings B21 identical to those A20 are fixedly installed on both the left and right sides of the vertical plate 17. Since the mounting rings A20 are fixedly connected to the pull head 1 by screws, it facilitates the disassembly and assembly of the mounting box 3. Since the mounting rings B21 identical to those A20 are fixedly installed on both the left and right sides of the vertical plate 17, when the user does not need to use the anti-theft function, the mounting box 3 can be disassembled, and the mounting rings B21 can be fixedly connected to the pull head 1 by screws, so that the pull tab 2 is directly fixed to the pull head 1, which allows the user to choose freely.
[0023] Preferably, a magnetic plate 22 is fixedly installed below the top plate 12, and an iron sheet is fixedly installed on the top wall of the mounting box 3. After the insert frame 13 is inserted into the through slot 16, the magnetic plate 22 is fixedly connected to the iron sheet on the top wall of the mounting box 3. Since the magnetic plate 22 is fixedly connected to the iron sheet on the top wall of the mounting box 3 after the insert frame 13 is inserted into the through slot 16, it further fixes the top plate 12 and prevents the top plate 12 from becoming loose when the pull tab 2 is pulled.
[0024] Preferably, a disk 23 is fixedly provided at the front end of the sliding column A8 and the rear end of the sliding column B9, and the diameter of the disk 23 is larger than the diameter of the sliding hole A14 and the sliding hole B15. Since the diameter of the disk 23 is larger than the diameter of the sliding hole A14 and the sliding hole B15, it serves to prevent the sliding columns A8 and B9 from sliding out of the sliding holes A14 and B15.
[0025] Preferably, the mounting box 3 is fixedly provided with a number of sharp rivets 24 on all four sides. Since the mounting box 3 is fixedly provided with a number of sharp rivets 24 on all four sides, when someone tries to pull the zipper 1, the sharp rivets 24 will prick their fingers, causing them to release their grip in pain, which further enhances the anti-theft function.
[0026] Preferably, a plurality of anti-slip ridges 25 are fixedly provided on the upper part of the pull tab 2. Since a plurality of anti-slip ridges 25 are fixedly provided on the upper part of the pull tab 2, they play a role in preventing slippage.
