Description

Technical Field

[0001] The utility model belongs to the technical field of zippers, and particularly relates to an anti-slip slider. Background Art

[0002] Zippers, as a connecting device, are very common in daily life. Existing zippers mainly consist of a pair of chain straps with chain teeth and a zipper puller. The zipper puller includes a pull tab, an upper cover, and a lower cover connected by a support core. The zipper puller slides on the chain straps, and the ribs on both sides of the zipper puller guide the chain teeth, bringing the two chain straps closer together and allowing the chain teeth to engage at intervals, thus connecting the two chain straps. However, the gap between the ribs and the chain teeth of the zipper puller can easily get caught in the surrounding fabric or thread during sliding, blocking the zipper puller. Pulling the zipper too hard at this time can even damage the zipper.

[0003] The pull cap on the existing slider is easily separated from the locking plate when the pull ring is pulled, making the entire slider unusable and unable to be replaced. The entire slider needs to be replaced, which is not only costly but also wastes resources. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides an anti-slip pull head, comprising a support and a lower hopper, comprising an upper locking plate and a lower locking plate, and further comprising a support core arranged between the upper locking plate and the lower locking plate, wherein a cap is arranged on the top of the upper locking plate through an easy-to-install and disassemble assembly, and a pull ring is arranged on the cap;

[0005] The easy assembly and disassembly component includes a left insertion hole, a right insertion hole and a limiting mechanism provided on the upper locking plate, and a left insertion column and a right insertion column fixed to the bottom of the cap, wherein the left insertion column is provided with a limiting hole.

[0010] As an anti-slip pull head of the utility model, preferably, a spring is sleeved on the pull rod inside the limiting sliding cavity, and the limiting sliding cavity and the left insertion hole are communicated with each other.

[0011] As an anti-slip pull head of the utility model, preferably, the limiting hole matches the limiting head, and the limiting head is clamped inside the limiting hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Pull the pull rod outward, and the pull rod drives the limit sliding plate to slide inside the limit sliding cavity and compresses the spring. At this time, the limit head disengages from the limit hole, completing the limit release, and then the cap can be removed from the upper locking plate. Conversely, pull the pull rod outward, and the pull rod drives the limit sliding plate to slide inside the limit sliding cavity and compress the spring. At this time, the left plug and the right plug at the bottom of the cap are respectively inserted into the left and right plug holes, and then the pull rod is released. At this time, the limit head is clamped in the limit hole, thereby completing the installation of the cap, facilitating the replacement of the cap, with low replacement cost and resource saving.
