1. Field of the Invention
The instant disclosure relates to a zipper head structure; more particularly, to a zipper head structure that prevents a pull tab of separating from the zipper.
2. Description of Related Art
In general, zippers are basic elements in clothing or accessories. Compare to buttons, the zippers are easier to use. A conventional zipper comprises a zipper head and a tape. The zipper head works with the tape to allow the pulling action. Recently, zippers has being used commonly for clothing, pants, backpack, and other accessories.

To address the above issues, the inventor proposes the following solution.
The instant disclosure provides a zipper head structure, which can improve the assembling process for reducing manufacturing effort and cost.
The disclosed zipper head structure comprises a slider body, a pull-tab, and a locking hook. The slider body has a top wall, a bottom wall, a connecting portion, and a protrusion. Both ends of the connecting portion are respectively connected with the top wall and the bottom wall. The protrusion is formed onto a top surface of the top wall. The protrusion is located on one end of the slider body. The connecting portion is formed on another end of the slider body. The pull-tab has a holding portion on one end and an opening formed on another end thereof. A hinge portion is defined in between the opening and the corresponding end of the pull-tab, with the hinge portion being opposite of the holding portion. The pull-tab is disposed on the top surface of the top wall. The protrusion is located in the opening of the pull-tab. The locking hook has a base portion which is located over the hinge portion. The locking hook is disposed on the top surface of the top wall. The base portion has a through hole. A stopper is downwardly formed by one side of the through hole. The hinge portion is disposed in between the protrusion and the stopper.
Based on the above, the zipper head structure of the instant disclosure uses the stopper of the locking hook that is integrately formed to block and confine the movement of the hinge portion. No stopper is required for the locking hook to restrict the movement of the pull-tab over the slider body. The advantages include reducing the assembling complexity of the zipper head structure, which reduces the manufacturing effort and cost, etc.
In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure. However, the appended drawings are merely shown for exemplary purposes, rather than being used to restrict the scope of the instant disclosure.

The slider body 1 further comprises a receiving slot 112 projected through the top wall 11 and formed on one end of the slider body 1. The connecting portion 13 is opposite of the receiving slot 112. Furthermore, the receiving slot 112 is disposed on one side of the protrusion 14.
A hooking portion 34 is formed by bending one end of the base portion 31, and wherein a clasping portion 35 is formed by bending another end of the base portion 31. Furthermore, the hooking portion 34 of the locking hook 3 projects through the receiving slot 112 of the slider body 1. The clasping portion 35 is secured to the connecting portion 13 of the slider body 1.
Notably, a mouth 36 is formed in between the base portion 31 and the clasping portion 35 of the locking hook 3, and wherein the protrusion 14 of the slider body 1 projects through the mouth 36 of the locking hook 3.
The pull-tab 2 is flake form, and wherein the locking hook 3 is integrately formed.
In addition, the pull-tab 2 further comprises a ridge 231, wherein the ridge 231 is connected with the hinge portion 23 and extends into the opening 22 of the pull-tab 2.

In use, when closing the zipper (not shown), the holding portion 21 of the pull-tab 2 is first pulled upward relative to the slider body 1. Next, the hinge portion 23 of the pull-tab 2 is disposed over the top surface 111 of the top wall 11 is defined as a pivot point. By pulling upward, the pull-tab 2 is rotated, such that the holding portion 21 is at the same end with the connecting portion 13. During pivoting, the ridge 231 of the pull-tab 2 would abut the locking hook 3, and wherein pressure would be apply to the locking hook 3 such that the hooking portion 34 of the locking hook 3 would be departed from the receiving slot 112. As a result, the zipper is closed. In addition, as the zipper is being closed by pulling the pull-tab 2, the hinge portion 23 of the pull-tab 2 abuts to the stopper 33 of the locking hook 3. The shape of the stopper 33 is not restricted. Thus, when using the zipper, the integrally formed locking hook 3 utilizes the stopper 33 under the base portion 31 to confine the movement of the hinge portion 23 of the pull-tab 2 over the top surface 111, to effectively keep the pull-tab 2 from separating with the slider body 1.
The disclosed zipper head structure mainly uses the stopper, which is integrally formed with the locking hook. When pulling the zipper relative to the slider body, the stopper of the locking hook can effectively confine the movement of the hinge portion of the pull-tab over the top surface of the slider body. Thereby, the locking hook does not need an additional element to confine the movement of the pull-tab over the slider body. As a result, the assembling complexity of the zipper head structure is reduced. Accordingly, the manufacturing procedure is simplified, and the manufacturing effort and cost can be saved.
