Description

Technical Field

[0001] This utility model relates to the field of clothing accessories technology, specifically a hidden, lockable, positionable zipper head with tooth protection function. Background Technology

[0002] The concealed zipper pull cleverly hides under the fabric during use, making clothing, bags, and other items look cleaner and more aesthetically pleasing, enhancing the overall texture. It operates smoothly and effortlessly, opening and closing without jamming, saving time and effort. Furthermore, its sturdy structure makes it durable and resistant to damage, able to withstand repeated opening and closing. The concealed design also reduces friction and snagging between the zipper and external objects, lowering the risk of damage and extending the lifespan of the item.

[0003] Existing invisible zippers, when in use, may cause difficulty in precise control when opening and closing due to shaking, especially in scenarios that require quick opening and closing. Shaking reduces operational efficiency, increases the frequency of repeated adjustments, and long-term friction between the zipper head and the outer thread of the zipper teeth will cause the outer thread of the zipper teeth to gradually wear down, become thinner, or even break. This will cause the fabric structure around the zipper teeth to become loose and fragile, resulting in problems such as jamming and unevenness during the opening and closing process, ultimately significantly shortening the overall lifespan of the zipper.

[0004] Therefore, a concealed, lockable, and positionable tooth-protecting zipper pull was proposed to solve the problems mentioned above. Utility Model Content

By opening a through hole below the inner hole, it prevents the electroplating water from corroding the spring, avoiding affecting the normal use of the spring and improving the stability of the spring. Furthermore, by opening symmetrical tooth protection grooves on one side of the middle of the base plate, it reduces the friction between the outer edge of the zipper teeth and the bottom plate of the zipper pull, achieving the effect of protecting the zipper teeth. The specific details are as follows:

[0018] 1. This invisible, lockless, positionable, tooth-protecting zipper pull features an inner hole in the center of the support core, with a spring installed in the center of the inner hole. This facilitates positioning of the zipper pull, preventing it from wobbling and reducing the frequency of repeated adjustments. This makes the zipper pull more convenient and quick to use, thus enhancing its practicality.

[0019] 2. This invisible, lockless, positionable, tooth-protecting zipper pull prevents electroplating water from remaining in the middle of the inner hole during electroplating by opening a through hole below the inner hole. This prevents the electroplating water from corroding the spring, avoiding affecting the normal use of the spring and improving the stability of the spring. Therefore, this invisible, lockless, positionable, tooth-protecting zipper pull is more practical.

[0020] 3. This invisible, lockless, positionable tooth-protecting zipper head features symmetrical tooth-protecting grooves on one side of the base plate. This reduces friction between the outer edge of the zipper teeth and the base plate, protecting the zipper teeth and extending their lifespan.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: an invisible, lockable, and positionable zipper head with tooth protection function, including a base plate 1; it also includes: a closing edge 2 fixedly connected to one side of the top of the base plate 1, a guide edge 3 fixedly connected to the top of the closing edge 2, and a tooth protection groove 11 opened on the side of the base plate 1 near the closing edge 2; the closing edge 2 and the guide edge 3 are symmetrically fixedly connected to both sides of the base plate 1; the tooth protection groove 11 is symmetrically opened in the middle of the closing edge 2; by opening symmetrical tooth protection grooves 11 on one side of the middle of the base plate 1, the friction between the outer edge of the zipper teeth and the base plate 1 of the zipper head is reduced, thereby achieving the effect of protecting the zipper teeth, reducing the gradual wear, thinning, or even breakage of the outer edge of the zipper teeth, which leads to the loosening and fragility of the fabric structure around the zipper teeth, causing problems such as jamming and non-smoothness during the opening and closing of the zipper, thus extending the service life of the zipper teeth, making the invisible, lockable, and positionable zipper head with tooth protection function more practical.

[0029] The base plate 1 has a support core 4 fixedly connected to the middle of one end of its top surface. An inner hole 5 is formed in the middle of one side of the top surface of the support core 4, and a through hole 6 is formed in the middle of one end of the inner hole 5. A positioning spring 7 is installed in the middle of the inner hole 5. The support core 4 is fixedly connected to the middle of the end of the base plate 1 away from the guide edge 3. The diameter of the inner hole 5 is 1.2mm, and the diameter of the through hole 6 is 0.7mm. The spring 7 fits into the inner hole 5, and the top of the spring 7 overlaps with the end of the pull tab 9 near the mounting groove 10. By forming a through hole 6 below the inner hole 5, the electroplating water in the middle of the inner hole 5 is prevented from remaining during the electroplating process of the zipper head, thus preventing the electroplating water from corroding the spring 7 and avoiding affecting its normal use. This improves the stability of the spring 7 and makes the external processing of the zipper head more convenient and faster. Therefore, this invisible, lock-free, positioning tooth-protecting zipper head is more practical.

[0030] The support core 4 has a mounting part 8 fixedly connected to one side of its top end. A pull tab 9 is provided on one side of the mounting part 8, and a mounting groove 10 is opened in the middle of one end of the pull tab 9. The mounting parts 8 are symmetrically arranged on both sides of the top end of the inner hole 5. The two sets of mounting parts 8 are connected to the pull tab 9 and the mounting groove 10 by bending. By opening the inner hole 5 in the middle of the support core 4 and installing the spring 7 in the middle of the inner hole 5, it is easy to position the pull tab 9 and prevent the pull tab 9 from shaking. This facilitates precise control of the zipper, reduces the frequency of repeated adjustments, and makes the zipper head more convenient and quick to use. Therefore, the practicality of this invisible, lockable, positionable tooth-protecting zipper head is enhanced.

[0031] Working principle: When processing this invisible, lockable, positionable tooth-protecting zipper head, while the support core 4 is being formed, an inner hole 5 and a through hole 6 are opened in the middle of the support core 4 near the mounting part 8. In the subsequent electroplating process, the through hole 6 removes the water trapped in the inner hole 5 during electroplating.

[0032] Next, the spring 7 is installed in the inner hole 5, and the pull tab 9 is connected to the mounting part 8 through the mounting groove 10. The mounting part 8 is then riveted towards the center to achieve the connection between the zipper head and the pull tab 9.

[0033] Finally, the zipper is inserted between the base plate 1, the closing edge 2, the guide edge 3 and the support core 4, and the line on the outside of the zipper teeth is aligned with the tooth protection groove 11 to reduce the wear of the zipper head on the zipper teeth.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
