A fixed buckle 3 is fixedly mounted on the top of the zipper head 1, and the fixed buckle 3 is U-shaped. A pull ring 4 is rotatably sleeved on the fixed buckle 3. The pull ring 4 is made of stainless steel and can be adsorbed by the magnet 5 mentioned below. A magnet 5 is fixedly mounted on the top of the zipper head 1, and the top of the magnet 5 is in contact with the bottom of the pull ring 4. A connecting block 6 is fixedly mounted on the top of the zipper head 1, and the bottom of the connecting block 6 is open. A sliding hole 7 is opened on one side of the connecting block 6, and the sliding hole 7 provides a sliding space for the slide rod 11 mentioned below. A fixed block 8 is slidably mounted in the connecting block 6, and a fixed block 8 is fixedly mounted in the connecting block 6. A mounting cavity 9 is provided on the fixed block 8, and two circular clamping holes 10 are provided on the side of the connecting block 6 away from the sliding hole 7. A sliding rod 11 is slidably installed on the fixed block 8, and both ends of the sliding rod 11 extend to the outside of the connecting block 6 through the sliding hole 7 and a circular clamping hole 10. The sliding rod 11 is slidably installed in the corresponding circular clamping hole 10, and a set block 12 is fixedly sleeved on the sliding rod 11. A spring 13 is sleeved on the sliding rod 11, and both ends of the spring 13 are respectively in contact with one side inner wall of the mounting cavity 9 and one side of the set block 12. A strip block 14 is fixedly installed at the bottom of the fixed block 8, and a rack 15 is fixedly installed at the bottom of the strip block 14. A plurality of teeth are fixedly installed at the bottom of the rack 15, and the gripping force of the rack 15 is increased by the plurality of teeth. A handle 16 is fixedly installed at one end of the sliding rod 11.
[0021] In order to provide space for the bar block 14 and the rack 15 to move and ensure that they can extend into the zipper head 1 and contact the base tape 2, a passage hole is opened on the top of the zipper head 1, and the passage hole is adapted to the bar block 14. The bar block 14 and the rack 15 are both slidably installed in the passage hole.
[0022] In order to increase the smoothness of sliding of the fixed block 8 and the set block 12 and reduce the wear on both of them, multiple rolling balls 1 are inlaid on both sides of the fixed block 8, and the multiple rolling balls 1 are respectively in contact with the two inner walls of the connecting block 6, and the top and bottom of the set block 12 are inlaid with rolling balls 2, and the two rolling balls 2 are respectively in contact with the top inner wall and the bottom inner wall of the installation cavity 9.
[0023] In order to reduce the impact of the impact force generated by the spring 13 on the set block 12, a cushion block is fixedly installed on one side of the set block 12, and the cushion block contacts the inner wall of one side of the fixed block 8. The cushion block is made of rubber material.
[0024] In order to reserve sliding space for the slide rod 11 and ensure the smooth sliding of the slide rod 11, circular holes are opened on both sides of the fixed block 8, and the inner walls of the two circular holes close to each other are respectively connected to the two sides of the mounting cavity 9, and the slide rod 11 is slidably connected to the inner walls of the two circular holes.
[0025] The working principle of the improved tear-resistant zipper provided by the utility model is as follows:
[0026] In this method, in the initial state, the strip block 14 is located in the connecting block 6, and the rack 15 is located above the two base bands 2, and the two are not in contact. When the zipper needs to be pulled, the pull ring 4 is pinched with the thumb and index finger, and then the pull ring 4 is rotated to make the pull ring 4 rotate counterclockwise with the fixed buckle 3 as the center of the circle. The pull ring 4 is erected to facilitate driving the zipper head 1 later. The zipper head 1 can be driven to slide on the two base bands 2 through the pull ring 4. After the zipper head 1 is driven to move to a suitable position through the pull ring 4, the control of the pull ring 4 is released. Under the attraction of the magnetic force of the magnet 5, the pull ring 4 will be kept in contact with the magnet 5 again.
[0027] Afterwards, the slide bar 11 is pulled by the handle 16. Under the action of external force, the slide bar 11 will gradually move out of the connecting block 6, and one end of the slide bar 11 will gradually slide out of the circular card hole 10 located above. The set block 12 moves at the same time driven by the slide bar 11. At this time, the spring 13 is squeezed and gradually deformed. After determining that the slide bar 11 has completely slid into the inside of the connecting block 6, while keeping pulling the handle 16, push the handle 16 downward. The handle 16 will drive the fixed block 8 to move downward in the connecting block 6 through the slide bar 11 until the bottom of the slide bar 11 contacts the bottom inner wall of the sliding hole 7, indicating that the fixed block 8 is already in the predetermined position at this time, and the slide bar 11 is now aligned with the circular card hole 10 located below.
[0028] Then slowly release the pull on the handle 16, and under the action of the elastic force of the spring 13, the slide bar 11 will gradually slide to the right and then be stuck in the corresponding circular hole 10, so as to fix the position of the fixing block 8. While the fixing block 8 moves, the rack 15 will be driven to move at the same time through the bar block 14, and the rack 15 will gradually slide from the passage hole to the zipper head 1 and contact the two base belts 2. The rack 15 exerts a limiting force on the two base belts 2. Under the action of the rack 15, the zipper head 1 and the two base belts 2 maintain a fixed connection relationship, thereby preventing the base belt 2 from easily sliding on the two base belts 2 when subjected to external force, affecting the stability of the position of the zipper head 1.
[0029] Compared with the related art, the improved tear-resistant zipper provided by the utility model has the following beneficial effects:
[0030] In the utility model, a rack 15 is arranged on the zipper head 1, and the position of the fixing block 8 and the sliding rod 11 is adjusted by the handle 16 so that the position of the rack 15 can be adjusted, thereby ensuring the stability of the position of the rack 15 and preventing the zipper from being affected by the rack 15 during use, so that the rack 15 has a self-locking function, which is convenient for ensuring the gripping force of the rack 15 on the two base belts 2 when the rack 15 is subsequently put down, thereby improving the position stability of the zipper head 1 on the two base belts 2, reducing the possibility that the zipper head 1 is easily affected by external forces, increasing the stability of the zipper head 1, and making the use of the zipper more flexible.
