Description

Technical Field

[0001] This utility model belongs to the field of clothing accessories technology, specifically relating to a zipper head with anti-slip function. Background Technology

[0002] Zippers, as a connecting component widely used in clothing, bags, tents and other products, have gained widespread recognition for their convenience and practicality. The zipper pull, as the core operating component of the zipper, directly affects the user experience and performance of the zipper.

[0003] In the use of traditional zippers, some zipper pulls are prone to coming off during exercise, causing considerable inconvenience to users. For example, in the clothing industry, when people wear zippered garments and engage in vigorous activities such as running, jumping, or stretching, the zipper pulls may slide down the zipper track and come off due to the large range of motion and the external force pulling the clothing, causing the garment to open. This not only affects the appearance of the garment but may also expose personal privacy. For outdoor products such as tents, in the complex environment of the wild, zippers are frequently used and may be affected by factors such as strong winds and rain. Once the zipper pull comes off, it will seriously affect the tent's sealing and protective functions, making it impossible to provide users with a safe and comfortable living space.

[0004] Therefore, a zipper pull with anti-slip function is designed to overcome the above-mentioned technical defects. Utility Model Content

Detailed Implementation

[0026] This specific embodiment is a zipper pull with anti-slip function, and its structural diagram is shown below. Figures 1-3 As shown, it includes a front shell 1 and a rear shell 2, which are U-shaped. A mounting shell 3 is fixedly connected to the front wall of the rear shell 2. A connecting mechanism is provided between the rear shell 2 and the front shell 1. A hollow sphere 6 is provided on the front side of the front shell 1. The connecting mechanism is fixedly connected to the hollow sphere 6. A handle 14 is installed on the hollow sphere 6. A secondary position fixing mechanism is provided inside the mounting shell 3.

[0027] The zipper head formed between the front shell 1 and the back shell 2 in this technical solution has the same function as conventional zipper heads on the market. Moreover, zipper heads are common clothing accessories on the market, and their installation methods and working principles are common knowledge. Therefore, they will not be described in detail in this technical solution.

[0028] like Figures 3-7 As shown, the connecting mechanism includes an internally threaded tube 4 located inside the mounting shell 3. The rear end of the internally threaded tube 4 is fixedly connected to the rear shell 2. A lead screw 5 is installed inside the internally threaded tube 4. The front end of the lead screw 5 passes through the front shell 1 and is movably connected to the front shell 1. The front end of the lead screw 5 is fixedly connected to the hollow sphere 6.

[0029] The distance between the front shell 1 and the back shell 2 can be easily adjusted through the connecting mechanism. The front shell 1 and the back shell 2 can clamp the regular zipper tape, thus fixing the position of the front shell 1 and the back shell 2 and preventing them from sliding down.

[0030] like Figures 3-7As shown, the secondary fixing mechanism includes two reinforcing blocks 11 located inside the mounting shell 3. Rectangular openings 12 are respectively provided on the left and right sides of the mounting shell 3. One side of the reinforcing block 11 passes through the rectangular opening 12 and extends to the outside of the mounting shell 3. One side of the reinforcing block 11 is arc-shaped, and the other side is inclined backward. Rectangular plates 16 are fixedly connected to the top and bottom of the two reinforcing blocks 11 respectively. The rectangular plates 16 are located inside the mounting shell 3. A pressure plate 13 is provided inside the mounting shell 3. The side of the pressure plate 13 opposite to the reinforcing block 11 is arc-shaped. The rear sidewall of the pressure plate 13 extends to the outside of the mounting shell 3 and is fixedly connected to the rear sidewall of the front shell 1.

[0031] When the zipper tape is clamped between the front shell 1 and the rear shell 2 by the secondary fixing mechanism, the two reinforcing blocks 11 will also be squeezed out of the mounting shell 3 by the pressure plate 13. The squeezed-out reinforcing blocks 11 will press against the toothed blocks on the zipper tape, thereby achieving the secondary fixing effect and effectively improving the stability of use.

[0032] like Figures 3-4 As shown, symmetrical limit plates 7 are arranged inside the mounting shell 3. The front sidewall of the limit plate 7 extends to the outside of the mounting shell 3 and is fixedly connected to the rear sidewall of the front shell 1. Limit blocks 8 are fixedly connected to the opposite sides of the two limit plates 7. Limit openings 9 are opened at the top and bottom of the mounting shell 3 respectively. One side of the limit block 8 extends into the limit opening 9.

[0033] The limiting plate 7 and the limiting opening 9 can limit the distance between the front shell 1 and the rear shell 2 to the farthest and the closest, so that the front shell 1 and the rear shell 2 will not separate. This mainly serves as a limiting function, and at the same time, it can prevent the front shell 1 and the rear shell 2 from not rotating when the lead screw 5 is rotated.

[0034] Among them, the front shell 1 and the rear shell 2 are respectively fixedly connected with uniformly distributed rubber pads 10 on the opposite side near the left and right sides. The rubber pads 10 can protect the zipper tape, avoid increasing the wear on the surface of the zipper tape, and at the same time have a good anti-slip effect, so that the friction is increased when the zipper tape is clamped between the front shell 1 and the rear shell 2.

[0035] In addition, two retaining plates 15 are fixedly connected to the left and right sides of the front shell 1 near the middle. The two retaining plates 15 are respectively arranged in an arc shape on the opposite side near the front. The retaining plates 15 can fix the handle 14 when needed, so that the handle 14 will not swing randomly during use.

[0036] Working Principle: When using this technical solution, the front shell 1 and rear shell 2 are first installed on a standard zipper. To prevent them from slipping downwards, the hollow ball 6 and lead screw 5 are rotated clockwise by the handle 14, gradually reducing the distance between the front shell 1 and rear shell 2. Simultaneously, the two limiting plates 7 slide into the mounting shell 3. When the rubber pads 10 on the front shell 1 and rear shell 2 clamp the zipper tape, their positions are fixed, thus securing the zipper head. This clamping prevents slippage. Furthermore, as the distance between the front shell 1 and rear shell 2 decreases, the pressure plate 13 also depresses deeper into the mounting shell 3, pressing the inclined surfaces of the two reinforcing blocks 11, thereby... Two reinforcing blocks 11 extend to both sides, which compress the teeth on the zipper tape, thus achieving secondary reinforcement and effectively preventing the zipper head from slipping off. When the zipper head needs to be pulled, first reverse the hollow ball 6 and the screw 5 by using the handle 14. With the cooperation of the screw 5 and the internal thread tube 4, the front shell 1 and the rear shell 2 are pushed away from each other, so that the rubber pad 10 does not contact the zipper tape. At the same time, the pressure plate 13 will also move away from the reinforcing blocks 11. Then the front shell 1 and the rear shell 2 can be pulled up and down. The extended reinforcing blocks 11 will be pushed into the mounting shell 3 by the displacement of the front shell 1, and there will be no jamming. The above operation can effectively solve the problem of the zipper head easily slipping off.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
