Description

Technical Field

[0001] The utility model belongs to the field of zippers, and in particular relates to a slider with a locking puller. Background Art

[0002] As a common switch device, the zipper includes a zipper belt and a slider. Because of its simple operation, the zipper belt can be switched by sliding the slider. It is often used to open or close the openings of clothes, backpacks, tents and other items. However, because the opening state can be switched by sliding, there is a situation where the tension between the zipper belts causes the slider to slide, which can easily cause the zipper belt to open by itself, and the reliability is not high. In order to improve the reliability of the zipper, the existing zipper is usually equipped with a self-locking mechanism. When the slider is in place, the self-locking mechanism locks the slider to prevent it from sliding.

[0003] In the prior art, a patent document with the announcement number CN208096221U discloses a self-locking zipper head, including a body, a cap, and a pull tab, characterized in that the upper end of the body has a sliding seat and a clamping seat, the two ends of the cap are horizontally protruding rotating ends and sliding ends, the sliding end of the cap has a downwardly protruding spike below, the spike can be inserted through the bar hole and snapped into the zipper, the rotating end has an arc-shaped covering sheet extending outward above, the covering sheet is wrapped around the outer side of the rotating seat, the covering sheet has elasticity, the end of the covering sheet is connected to the body and the cap is close to the body. The zipper head realizes self-locking by inserting the spike through the bar hole and snapping into the zipper, but the zipper head needs to be unlocked by the pull tab, and the connection between the pull tab and the zipper head is relatively weak and easy to be damaged. When the pull tab is damaged, the zipper head cannot be unlocked, and the reliability is not high.

[0004] Therefore, there is an urgent need for a slider with a lock puller to solve the above problems. Summary of the invention

[0005] In response to the problems in the prior art, the utility model proposes a slider with a lock pull head. The slider is slidably connected to the pull body through a slide rail. The self-locking pull head is unlocked by sliding the slider, which increases the contact area between the slider and the pull body, makes the connection between the slider and the pull body less prone to damage, and improves the reliability of the pull head.
