Description

Technical Field

[0001] This utility model relates to the field of zipper head technology, and in particular to a zipper head device that can rotate at multiple angles. Background Technology

[0002] The zipper pull mainly consists of a zipper head and a pull tab. The zipper head is usually U-shaped or similar and has a specific internal structure. When the zipper head moves along the zipper teeth, the zipper teeth are engaged and disengaged through this structure, thereby completing the opening and closing operation of the zipper. The pull tab provides the user with a point of force to easily pull the zipper head.

[0003] The above-mentioned and existing technologies have the following drawbacks: the pull tab and the zipper head are usually connected by a fixed pin or an integrated injection-molded connector. The fixed pin only allows the pull tab to rotate around the pin within a certain angle range, while the integrated connector directly restricts the freedom of movement of the pull tab, resulting in the range of movement of the pull tab being strictly limited to a fixed plane parallel to the length direction of the zipper head. Therefore, in scenarios such as putting on and taking off clothes during sports or operating with one hand, users need to frequently adjust the angle of their hand grip to adapt to the fixed plane of the zipper head and the pull tab, thereby reducing the practicality of the zipper head.

[0004] Therefore, a zipper head device that can rotate at multiple angles is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that users need to frequently adjust the angle of their hand to fit the fixed plane of the zipper head and the zipper tab in scenarios such as sports, dressing and undressing, and one-handed operation, and proposes a zipper head device that can rotate at multiple angles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a zipper head device that can rotate at multiple angles, including a zipper head body, a fixing block fixedly connected to the surface of the zipper head body, a rotating frame rotatably connected to the surface of the fixing block, a ball bearing rotatably connected inside the rotating frame, a connecting rod engaged inside the ball bearing, and a pull tab fixedly connected to one end of the connecting rod.

[0007] The effect achieved by the above components is as follows: by setting a fixed block, a rotating frame, a ball bearing, a connecting rod, and a pull tab, when the pull tab is pulled in any direction during the opening and closing of the zipper, the ball bearing rolls in the rotating frame, and the rotating frame rotates around the fixed block in a plane parallel to the surface of the zipper head. The two work together to allow the pull tab to be flexibly adjusted according to the angle of the hand force, without the need to frequently change the hand posture, making the operation smoother and suitable for various scenarios such as sports dressing and undressing, and one-handed operation.

[0008] Preferably, the surface of the rotating frame is provided with a groove that matches the connecting rod.

[0009] The effect achieved by the above components is that, in the idle state, the connecting rod will be located on the inner wall of the groove, and the groove can prevent the connecting rod from tilting up due to the obstruction of the rotating frame.

[0010] Preferably, a strong magnetic block is fixedly connected to the rotating frame relative to the groove, and the connecting rod is an iron rod that has undergone rust prevention treatment.

[0011] The effect achieved by the above components is that the strong magnetic block on the rotating frame will attract the connecting rod made of iron rod, so that the pull tab remains stable and does not shake randomly.

[0012] Preferably, the circumferential surface of the ball is provided with a relief groove, and a bolt is slidably connected to the inner wall of the relief groove. The bolt passes through the ball and is threadedly connected to the connecting rod.

[0013] The effect achieved by the above components is that the bolts can securely connect the ball bearings to the connecting rod.

[0014] Preferably, the inner wall of the relief groove is interference-fitted with an elastic plug.

[0015] The effect achieved by the above components is that the elastic plug in the relief groove can seal the relief groove and prevent impurities from entering the relief groove.

[0016] Preferably, an anti-slip ring is fixedly connected to the inner wall of the relief groove, and the anti-slip ring abuts against the circumferential surface of the elastic plug.

[0017] The effect achieved by the above components is that the anti-slip ring can further increase the friction between the elastic plug and the relief groove.

[0018] Preferably, the surface of the pull tab is fixedly connected with several arc-shaped strips.

[0019] The effect achieved by the above components is that the curved strip can increase hand friction, improve grip comfort, and prevent slippage.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting a fixed block, a rotating frame, a ball bearing, a connecting rod, and a pull tab, when the pull tab is pulled in any direction during the opening and closing of the zipper, the ball bearing rolls inside the rotating frame, and the rotating frame rotates around the fixed block in a plane parallel to the surface of the zipper head. The two work together to allow the pull tab to be flexibly adjusted according to the angle of the hand force, without the need to frequently change the hand posture, making the operation smoother and suitable for various scenarios such as sports dressing and doffing, and one-handed operation.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-4 As shown, this utility model provides a zipper head device that can rotate at multiple angles, including a zipper head body 1. A fixing block 2 is fixedly connected to the surface of the zipper head body 1. A rotating frame 3 is rotatably connected to the surface of the fixing block 2. A ball bearing 4 is rotatably connected inside the rotating frame 3. A connecting rod 5 is engaged inside the ball bearing 4. A pull tab 6 is fixedly connected to one end of the connecting rod 5. By setting the fixing block 2, rotating frame 3, ball bearing 4, connecting rod 5 and pull tab 6, when the pull tab 6 is pulled in any direction during the opening and closing of the zipper, the ball bearing 4 rolls inside the rotating frame 3, and the rotating frame 3 rotates around the fixing block 2 in a plane parallel to the surface of the zipper head body 1. The two work together to allow the pull tab 6 to be flexibly adjusted according to the angle of the hand force, without the need to frequently change the hand posture, making the operation smoother and suitable for various scenarios such as sports dressing and undressing, and one-handed operation.

[0030] like Figure 2 As shown, the surface of the rotating frame 3 has a groove 7 that matches the connecting rod 5. In the idle state, the connecting rod 5 will be located on the inner wall of the groove 7. The groove 7 can prevent the connecting rod 5 from tilting due to the obstruction of the rotating frame 3. A strong magnetic block 8 is fixedly connected to the rotating frame 3 relative to the groove 7. The connecting rod 5 is an iron rod. The strong magnetic block 8 on the rotating frame 3 will attract the iron rod connecting rod 5, so that the pull piece 6 remains stable and does not shake randomly.

[0031] like Figures 2-4 As shown, a relief groove 9 is provided on the circumferential surface of the ball 4. A bolt 10 is slidably connected to the inner wall of the relief groove 9. The bolt 10 passes through the ball 4 and is threadedly connected to the connecting rod 5. The bolt 10 can securely connect the ball 4 and the connecting rod 5. An elastic plug 11 is interference-fitted to the inner wall of the relief groove 9. The elastic plug 11 in the relief groove 9 can seal the relief groove 9 and prevent impurities from entering the relief groove 9. An anti-slip ring 12 is fixedly connected to the inner wall of the relief groove 9. The anti-slip ring 12 abuts against the circumferential surface of the elastic plug 11. The anti-slip ring 12 can further increase the friction between the elastic plug 11 and the relief groove 9.

[0032] like Figure 3 As shown, several arc-shaped strips 13 are fixedly connected to the surface of the pull tab 6. The arc-shaped strips 13 can increase hand friction, improve grip comfort, and prevent slippage.

[0033] The overall working principle is as follows: When the user operates the multi-angle rotating zipper head device, in the idle state, the connecting rod 5 will be located on the inner wall of the groove 7. The groove 7 can prevent the connecting rod 5 from tilting due to the obstruction of the rotating frame 3. The strong magnetic block 8 on the rotating frame 3 will attract the iron rod connecting rod 5, keeping the pull tab 6 stable and preventing it from shaking. At the same time, it allows the elastic plug 11 and the anti-slip ring 12 in the groove 9 to seal the gap and prevent impurities from entering. The bolt 10 secures the connection between the ball 4 and the connecting rod 5. When the zipper needs to be opened or closed, the user holds the pull tab 6, and the arc strip 13 on its surface can increase hand friction. The pull tab 6 is designed to enhance grip comfort and prevent slippage. When the pull tab 6 is pulled in any direction, the pulling force easily overcomes the magnetic attraction force, causing the connecting rod 5 to move synchronously. At this time, the ball bearing 4 rolls inside the rotating frame 3, and the rotating frame 3 rotates around the fixed block 2 in a plane parallel to the surface of the zipper head body 1. The two work together to allow the pull tab 6 to flexibly adjust the angle of the hand according to the force applied, without having to frequently change the hand posture. As the pull tab 6 is pulled, the zipper head body 1 moves along the zipper teeth, realizing the engagement and disengagement of the zipper teeth, and finally smoothly completing the opening and closing operation of the zipper. The operation is smoother and suitable for various scenarios such as sports dressing and undressing, and one-handed operation.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
