Description

Technical Field

[0001] This utility model relates to the field of zipper head technology, and in particular to an anti-sway zipper head. Background Technology

[0002] The zipper pull is a crucial component of a zipper. It's a moving part that allows the zipper teeth to engage or disengage. However, in daily use, we've found that after the zipper is closed, the zipper pull tab, which is attached using a hook-and-loop method, swings with the user's movements during operation. Furthermore, traditional zipper pulls lack a structure to restrict and position the zipper pull tab, making it easy for it to strike the user's neck or jaw area, resulting in a poor user experience. Some specially shaped zipper pull tabs can even cause injury to the user.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes an anti-sway zipper head, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: an anti-sway zipper head includes a fixing pin, two symmetrically distributed slots 1 are formed on the surface of the fixing pin, a movable frame is sleeved on the surface of the fixing pin, a sliding groove 1 is formed on one side of the inner cavity of the movable frame, a locking pin 1 is slidably installed in the inner cavity of the sliding groove 1, a spring 1 is fixedly connected to one end of the locking pin 1, and the end of the spring 1 away from the locking pin 1 is fixedly connected to the inner wall of the sliding groove 1. A sliding groove 2 is formed on one side of the inner cavity of the movable frame, a fixing block is fixedly connected to the inner cavity of the sliding groove 2, a locking pin 2 that matches the slot 1 is provided through one side of the fixing block, a locking pin 3 is fixedly connected to one end of the locking pin 2, and springs 2 are sleeved on both sides of the surface of the locking pin 2.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0026] An anti-sway zipper head includes a fixing pin 1, two symmetrically distributed slots 2 on the surface of the fixing pin 1, a movable frame 3 sleeved on the surface of the fixing pin 1, a sliding groove 4 on one side of the inner cavity of the movable frame 3, a locking pin 5 slidably installed in the inner cavity of the sliding groove 4, a spring 6 fixedly connected to one end of the locking pin 5, and the end of the spring 6 away from the locking pin 5 fixedly connected to the inner wall of the sliding groove 4, a second sliding groove 7 on one side of the inner cavity of the movable frame 3, a fixing block 8 fixedly connected to the inner cavity of the second sliding groove 7, a locking pin 9 adapted to the slot 2 penetrating one side of the fixing block 8, a third locking pin 10 fixedly connected to one end of the second locking pin 9, and springs 11 sleeved on both sides of the surface of the second locking pin 9, with the two ends of the two springs 11 fixedly connected to the third locking pin 10 and the fixing block 8, and the second locking pin 9 and the fixing block 8, respectively.

[0027] This utility model adopts a structural design in which the zipper pull can be positioned when not in use. After the user finishes using the zipper, the pull on the zipper head will be positioned by the matching internal structure, so that even when the user is driving or moving, the pull will not swing with the user's movement posture, thereby avoiding the pull from hitting the user, improving the user experience and safety, and providing convenience for the user.

[0028] The specific working process is as follows: First, when the user is not operating the zipper head, the locking pin 3 10 is engaged in the locking groove 2 13 on the rotating pin 12. At the same time, the locking pin 1 5 is also engaged in the locking groove 1 2. When the user uses it, they directly pinch the pull tab 15 or the auxiliary pull ring 16, and then rotate the pull tab 15 180 degrees, changing its original orientation to an upward orientation. During this process, the fixing pin 1 rotates in the movable cavity 14 on the movable frame 3, and the movable frame 3 also rotates around the fixing pin 1. When the movable frame 3 rotates, the locking pin 1 5 is squeezed by the outer surface of the fixing pin 1, and will move out of the current locking groove 1 2 and into the sliding groove 1 4, while compressing the spring 1 6. This continues until the movable frame 3 rotates 180 degrees, and the spring 1 6 compresses. When used, the latch 5 pops out of the inner cavity of the sliding groove 4 and engages with another groove 2 on the opposite side of the current groove 2. This positions the movable frame 3 in its current state, with the pull tab 15 facing upwards. The user can then pinch the pull tab 15 and pull the entire zipper. During this pulling process, as the position of the pull tab 15 changes, the angle of the pull tab 15 also changes with the pulling posture. The pull tab 15 then drives the rotating pin 12 to rotate within the movable frame 3. As the rotating pin 12 moves, it pushes the latch 3 10 out of the inner cavity of the groove 2 13. At the same time, the latch 3 10 also drives the latch 2 9 to slide on the fixed block 8. The spring 2 11 connected to the latch 3 10 is compressed, and the spring 2 11 connected to the latch 2 9 is compressed. Spring 11 will be stretched, and then pin 9 will engage with the corresponding slot 2, further positioning the movable frame 3 and preventing it from swinging arbitrarily. This continues until the user finishes using the zipper and releases pull tab 15, and then controls pull tab 15 to reset rotating pin 12. This causes pin 10 to engage with slot 13 under the action of spring 11, while pin 9 moves out of slot 2. Then, pull tab 15 or auxiliary pull ring 16 is controlled to rotate the movable frame 3, or the movable frame 3 can be rotated directly. The movable frame 3 is then rotated 180 degrees, causing pull tab 15 to face downwards. During this process, pin 5 is again pressed into sliding groove 4, and then ejected from the inner cavity of sliding groove 4 under the action of spring 6, and then engages again. The zipper head moves into slot 2 at its current position, positioning the movable frame 3. This returns both the movable frame 3 and the pull tab 15 to their unused state. The rotating pin 12 and the pull tab 15 are then secured by the locking pin 3 10. The movable frame 3 is further secured by the sliding groove 4 and the fixing pin 1, preventing the pull tab 15 and the movable frame 3 from swinging during user activity. This avoids the pull tab 15 and the movable frame 3 hitting the user, improving the user experience. Therefore, a structural design is adopted where the pull tab can be positioned when the zipper head is not in use. After the user finishes using the zipper, the pull tab on the zipper head is positioned by the internal matching structure, ensuring that the pull tab will not swing with the user's movements even while driving or exercising, thus preventing the pull tab from hitting the user.To improve user experience and security, and to provide convenience for users.

[0029] A rotating pin 12 is provided through one side of the movable frame 3, and a slot 13 adapted to the locking pin 10 is provided on one side of the rotating pin 12.

[0030] Specifically, the rotating pin 12 and the slot 2 13 are designed so that the slot 2 13 is adapted to the locking pin 3 10. When the locking pin 3 10 is locked in the slot 2 13, it can restrict the rotation of the rotating pin 12. When the locking pin 3 10 is moved out of the slot 2 13, the rotating pin 12 can rotate smoothly. It should be noted that this is without the intervention of external force, thus providing assistance and convenience for the user's work.

[0031] Pull tabs 15 are fixedly connected to both ends of the rotating pin 12.

[0032] Specifically, the pull tab 15 is part of the zipper and is used by the user to pinch it. In this way, the user can use the pull tab 15 to drive the zipper head body 17 to move on the zipper tape, so as to realize the engagement and opening of the zipper tape, thereby providing assistance and convenience for the user's work.

[0033] The top of the pull tab 15 has a mounting thread groove 18 on one side, and an auxiliary pull ring 16 is installed in the internal thread of the mounting thread groove 18.

[0034] Specifically, regarding the auxiliary pull ring 16 and the mounting threaded groove 18, the auxiliary pull ring 16 can be installed in the mounting threaded groove 18, that is, installed on the pull tab 15, or it can be removed from the pull tab 15. In actual use, the user can pull the pull tab 15 by pinching the auxiliary pull ring 16. Because the auxiliary pull ring 16 protrudes outward, it makes it easier for the user to pinch the auxiliary pull ring 16, providing assistance and convenience for the user's actual use. At the same time, it also plays a decorative role, enhancing the aesthetics of the zipper head.

[0035] The bottom of the fixing pin 1 is fixedly installed with the zipper head body 17.

[0036] Specifically, the zipper head body 17 is designed to fit the zipper tape and is used to engage and open the zipper tape, ensuring the normal operation of the zipper. During installation and use, the zipper tape passes through the zipper head body 17, thus providing assistance and convenience for the user.

[0037] The movable frame 3 has a movable cavity 14 on one side of its top, and the movable cavity 14 is connected to the sliding groove 4 and the sliding groove 7.

[0038] Specifically, the movable cavity 14 is used to install the fixing pin 1, and the fixing pin 1 can rotate flexibly within the movable cavity 14, thereby ensuring that the movable frame 3 can rotate flexibly on the fixing pin 1. At the same time, this also allows the locking pin 1 5 and locking pin 2 9 to be hidden inside the movable frame 3, thereby improving the aesthetics of the zipper head and providing convenience for the user's work.

[0039] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
