Figure 2As shown, to facilitate zipper installation, zipper guide grooves 4 are provided on both sides of the middle part of the zipper head seat 1. To facilitate the traction connection of the zipper head seat 1, a traction top seat 3 is provided on the upper part of the zipper head seat 1. The traction top seat 3 is fixedly installed on the middle of the top side of the zipper head seat 1. To facilitate the connection and installation of the self-locking spring 2, a spring mounting groove 5 is provided in the middle of the traction top seat 3. A limiting insert 6 is provided on the upper part of the self-locking spring 2. After installation, the limiting insert 6 and the spring mounting groove 5 are fitted and riveted together. The structure is simple and the operation is reliable.

[0026] The self-locking spring 2 is a steel spring. To achieve self-locking and limiting, see attached... Figure 4 As shown, a self-locking limiting block 7 is provided at the lower part of the self-locking spring 2. To facilitate the connection and installation of the self-locking limiting block 7, a rectangular through groove 8 is provided through the upper part of the zipper guide groove 4. The self-locking limiting block 7 is movably installed through the inner side of the rectangular through groove 8. The spring-type self-locking structure is adopted. The self-locking spring 2 is riveted and installed using the spring mounting groove 5. After the zipper head seat 1 is closed, the self-locking limiting block 7 at the lower part of the self-locking spring 2 is engaged with the zipper teeth to achieve the self-locking of the zipper head seat 1. To unlock, simply pull the traction pull head 12. The self-locking limiting block 7 can be moved upward and unlocked by the abutment and push of the connecting ring seat 10. The structure is simple and the operation is reliable, which can effectively improve the convenience of using the zipper.

[0027] The traction mechanism is used for pulling and driving the headstock mechanism. The traction mechanism includes a connecting ring seat 10, a ring seat connecting block 11, a traction pull head 12, and a connecting bolt 13. The connecting ring seat 10 is a steel ring seat. The front part of the connecting ring seat 10 is inserted and snapped into the inner side of the groove in the middle of the traction top seat 3 for traction connection. To reduce contact friction, as shown in the attached... Figure 4 As shown, an arc-shaped protrusion 9 is formed by stamping in the middle of the self-locking spring piece 2. When pulled, the front part of the connecting ring seat 10 abuts against the arc-shaped protrusion 9, as shown in the attached figure. Figure 5 As shown, the rear of the connecting ring seat 10 is open. To facilitate connection and installation with the connecting ring seat 10, an installation recess is provided at the front of the ring seat connecting block 11. Installation holes are provided on both sides of the installation recess. The rear end post of the connecting ring seat 10 is inserted into the inner side of the installation holes. A split-type traction structure is adopted, utilizing the semi-open connecting ring seat 10 to connect with the zipper head seat 1. The connecting ring seat 10 and the ring seat connecting block 11 are engaged and limited by slotted holes. When needed, the connecting ring seat 10 and the ring seat connecting block 11 can be quickly disassembled and separated by side pressure, facilitating the maintenance and replacement of the zipper head structure.

[0028] The traction head 12 is rotatably mounted on the rear of the ring seat connecting block 11 via the connecting bolt 13, as shown in the attached figure. Figure 5As shown, to facilitate the connection and installation of the connecting bolt 13, a bolt mounting hole is provided through the middle of the front side of the traction head 12. The connecting bolt 13 is movably inserted and installed inside the bolt mounting hole. The end of the connecting bolt 13 is fastened to the fastening screw hole provided at the rear of the ring seat connecting block 11 through the thread. The traction head 12 is rotatably installed at the rear of the ring seat connecting block 11 by the support of the connecting bolt 13. The rotating structure can prevent the torsional force from being transmitted to the connecting ring seat 10 side when subjected to torsional tension, which can effectively reduce the risk of torsional damage to the zipper head. In order to reduce the contact friction force on the nut side of the connecting bolt 13, an annular gasket 14 is movably installed at the rear of the connecting bolt 13.

[0029] Working principle or structural principle: In use, the zipper teeth are aligned and fitted into the zipper guide groove 4 on the side of the zipper head seat 1. Then, by pulling the zipper head seat 1 up by the pull zipper head 12, the zipper closes and locks under the alignment and pushing action of the side wall of the zipper guide groove 4, completing the zipper closing operation. After the zipper is locked, the self-locking spring 2 pushes the teeth of the self-locking limit block 7 at the bottom, which engages and locks with the zipper teeth, preventing the zipper head seat 1 from loosening and moving down. To unlock the zipper, simply pull the pull zipper head 12 in opposite directions. The end of the pulled connecting ring seat 10 contacts and presses against the arc-shaped protrusion 9 in the middle of the self-locking spring 2. Through the pushing action, the self-locking limit block 7 moves up and engages with the zipper teeth. After the teeth are separated, simply pull down to move the zipper head seat 1 to complete the zipper opening and unlocking operation. During the pulling process, when the traction zipper head 12 is subjected to torsional pulling force, the rotating structure can cause the traction zipper head 12 and the ring seat connecting block 11 to rotate axially to dissipate the torsional force, so that the connecting ring seat 10 can pull the traction top seat 3 in the positive direction, which can effectively reduce the risk of torsional damage to the zipper head. When the zipper head structure is damaged, simply press the side to make the end of the connecting ring seat 10 retract and separate from the slot on the side of the ring seat connecting block 11, so as to disassemble and separate the connecting ring seat 10 and the ring seat connecting block 11. Then, replace with a brand new zipper head structure to complete the replacement work.

[0030] In summary, this zipper head adopts a spring-type self-locking structure. The self-locking spring 2 is riveted and installed using the spring mounting slot 5. After the zipper head seat 1 is closed, the self-locking limiting block 7 at the lower part of the self-locking spring 2 engages with the zipper teeth, achieving self-locking of the zipper head seat 1. To unlock, simply pull the traction head 12; the self-locking limiting block 7 moves upward and unlocks through the abutment and push of the connecting ring seat 10. The structure is simple and reliable, effectively improving the ease of use of the zipper. Furthermore, it adopts a split traction structure, utilizing a semi-open design. The connecting ring seat 10 is connected to the zipper head seat 1 by traction. The connecting ring seat 10 and the ring seat connecting block 11 are installed by locking and limiting through the slot. When needed, the connecting ring seat 10 and the ring seat connecting block 11 can be quickly disassembled and separated by pressing from the side, which can facilitate the maintenance and replacement of the zipper head structure. The traction zipper head 12 is rotated and installed at the rear of the ring seat connecting block 11 by the connecting bolt 13. The rotating structure can prevent the torsional force from being transmitted to the connecting ring seat 10 side when subjected to torsional tension, which can effectively reduce the risk of torsional damage to the zipper head.
