Description

Technical Field

[0001] This utility model relates to the field of clothing and bag accessories technology, specifically a zipper with a detachable zipper tab. Background Technology

[0002] Zippers, as a core opening and closing accessory used in daily life and industry, have long transcended their basic function of "connecting fabrics." From down jackets for windproof warmth in winter, jeans for daily commutes, and backpacks for carrying personal belongings, to waterproof tents for outdoor camping, hard-shell suitcases for long-distance travel, and even protective covers for heavy equipment in industrial settings, the stability and convenience of zippers directly determine the user experience and durability of products. They are both a "barrier" ensuring the safe storage of items and a "link" improving product operational efficiency; their importance is self-evident in various scenarios. With users' increasing demands for personalization and functionality, detachable zipper pulls are gradually becoming a market trend—users can customize the product's appearance by replacing zipper pulls with different styles and materials, or replace damaged zipper pulls individually to reduce maintenance costs.

[0003] However, existing detachable zipper pull technology has obvious drawbacks, such as cumbersome installation and removal. Most detachable zipper pulls made of metal adopt a "slot-type" design, which requires precise alignment with the small slot of the zipper head and then pressing hard to lock it in place. This requires a lot of effort to complete the operation, and nails can easily be pinched. It is even more inconvenient for female users who have manicured nails, thus limiting its applicability. Utility Model Content

[0004] The purpose of this invention is to provide a zipper with a detachable zipper tab to solve the problems of cumbersome installation and disassembly and limited applicability mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper with a detachable zipper piece, comprising a zipper head seat, with baffles symmetrically installed downwards on both sides of the zipper head seat, a connecting post fixedly installed below the zipper head seat, a zipper head base fixedly installed at the bottom of the connecting post, a pin hole opened at the top of the zipper head seat, the pin hole extending into the interior of the connecting post, a pin post installed in the pin hole, a pin hole seat fixedly installed at the top of the pin post, pin holes through-opening on both sides of the pin hole seat, a rotating shaft rotatably installed in the pin holes, and zipper pieces fixedly installed on both sides of the rotating shaft. The baffles are responsible for fixing the zipper in the zipper head when the zipper is pulled, limiting the lateral displacement of the zipper teeth, preventing derailment and failure, and avoiding injury or entanglement of the human body or clothing fabric by the zipper head or zipper teeth. The zipper piece is connected to the zipper head by a pin, enabling quick and convenient installation and removal.

[0006] Preferably, the top of the zipper head seat has a groove, a sliding post is fixedly installed in the groove, and a spring is fixedly installed on the outside of the sliding post. One end of the spring is fixedly connected to a slider, and the other end is fixedly connected to the end face of the groove. The slider has a through hole that matches the sliding post. The presence of the sliding post allows each turn of the spring to move along the outer wall of the sliding post, forcing the spring to maintain "axial extension and contraction" and avoiding deviation, which could lead to uneven force, increased wear, or even failure.

[0007] Preferably, the slide groove is symmetrically provided with card slots on both sides, and card plates are symmetrically installed on both sides of the slider. The card slots are adapted to the card plates. A stop block is fixedly installed on the side of the slider. The lower surface of the stop block coincides with the upper surface of the pin post. The card plate is engaged in the card slot to ensure that the slider moves along the plane of the slide groove. The stop block fixes the pin post in the pin hole to prevent the zipper piece from falling off.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. The zipper with detachable zipper tabs has a baffle that is responsible for fixing the zipper inside the zipper head when the zipper is pulled, limiting the lateral displacement of the zipper teeth, preventing derailment and failure, and avoiding injury or entanglement of the human body or clothing fabric by the zipper head or zipper teeth. This ensures that the zipper can be used smoothly while effectively preventing injury to the human body or clothing fabric.

[0010] 2. This zipper features a detachable zipper tab. The connection between the zipper tab and the zipper head is achieved through an embedded structure of "pin-slot," which greatly simplifies the disassembly and assembly process. Even female users with long manicures can easily disassemble and assemble it.

[0011] 3. In this zipper with a detachable zipper tab, the presence of the slide bar allows each turn of the spring to move along the outer wall of the slide bar, forcing the spring to maintain "axial extension and contraction" and avoiding deviation, which would lead to uneven force, accelerated wear, or even failure.
