Description

Technical Field

[0001] The utility model relates to the technical field of nylon zippers, in particular to a nylon zipper with a locking function. Background Art

[0002] Zippers are connectors that rely on continuously arranged chain teeth to connect or separate items. They are widely used in clothing, bags, tents, etc. Nylon zippers are made of nylon material. Nylon has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance, self-lubrication, and a low friction coefficient.

[0003] A typical zipper consists of two strips, each with a row of metal or plastic teeth, connecting the edges of an opening. A slider pulls the two rows of teeth into an interlocking position, sealing the opening. However, over extended use, the zipper pull can slide downward, preventing the plastic teeth from remaining closed. Therefore, we developed a nylon zipper with a locking function to address this issue. Utility Model Content

The pull tab 9 drives the connecting posts 10 on both sides of the pull nose 7 to move inside the sliding grooves 15 opened on both sides of the connecting seat groove 8. The locking block 14 is telescopically toggled inside the movable groove 13 at the top of the zipper head 5 by the telescopic spring 12. The traction rope 11 at the bottom of the traction rope 11 passes through the zipper head 5 and the telescopic spring 12 inside the movable groove 13 and is connected to the locking block 14;

[0026] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, by setting a locking structure, when in use, the pull nose 7 drives the zipper head 5 to slide outside the miter tooth 3 to close the miter tooth 3, and the locking block 14 of the movable groove 13 inside the zipper head 5 is clamped to the miter tooth 3 through the telescopic spring 12, so that the zipper head 5 is locked outside the miter tooth 3, and then the pull nose 7 at the front end of the zipper head 5 is pulled by the pull tab 9, and the connecting columns 10 on both sides of the front end of the pull nose 7 are allowed to slide in the sliding grooves 15 on both sides of the connecting seat groove 8 at the front end of the zipper head 5, and the pull nose 7 drives the traction rope 11 to pull the locking block 14, and the locking block 14 is retracted by the telescopic spring 12 and the traction rope 11, so that the zipper head 5 can slide open outside the miter tooth 3, thereby realizing the locking function.

[0027] The front end of the connecting tape 1 is coated with an adhesive layer 17, and the front end of the adhesive layer 17 is covered with an anti-sticking layer 16;

[0028] The connecting tape 1, the adhesive layer 17 and the anti-adhesive layer 16 are connected in sequence, and the anti-adhesive layer 16 covers the front end of the adhesive layer 17 coated on the front end of the connecting tape 1;

[0029] Specifically, if Figure 1 and Figure 4 As shown, by setting a convenient fixing structure, when in use, the anti-sticking layer 16 set at the front end of the connecting tape 1 is peeled off from the adhesive layer 17 at the front end of the connecting tape 1, so that the connecting tape 1 is first contacted and fixed through the adhesive layer 17, and the nylon zipper is adhesively connected through the connecting tape 1, thereby realizing a convenient fixing function, or further reinforcing it with needle and thread to increase the use scenarios of the nylon zipper.

[0030] An upper stopper 2 is installed on the inner side of the connecting tape 1, a rotating shaft 18 is provided on the front end side of the upper stopper 2, and a clamping block 19 is installed inside the upper stopper 2;

[0031] The upper stop head 2 rotates on the inner side of the connecting tape 1 through the rotating shaft 18. The upper stop head 2 is fixed to the inner side of the connecting tape 1 through the clamping block 19. The upper stop head 2 is fixed to the inner side of the connecting tape 1 and is placed on the top of the miter tooth 3.

[0032] Specifically, if Figure 1 and Figure 5 As shown, by setting a movable anti-slip structure, the upper stop head 2 set on the top of the common miter tooth 3 can prevent the zipper head 5 from sliding out through the top of the miter tooth 3. However, since the zipper head 5 will also detach from the middle section, the upper stop head 2 is flipped on the inner side of the connecting tape 1 through the rotating shaft 18.
