Description
Technical Field
[0001] This utility model relates to the field of pull tab technology, specifically to an adjustable pull tab. Background Technology
[0002] In the field of clothing design and manufacturing, zippers are a key component of garments, serving both functional and decorative purposes. Their main function is to adjust the tightness of the garment, for example, by adjusting the tightness of cuffs, shoulder width, and waist circumference to accommodate different wearers' measurements or different wearing occasions, thereby improving the fit and comfort of the garment.
[0003] Currently, the mainstream adjustable cuff system on the market mainly relies on Velcro (also known as hook and loop fasteners). This structure is widely used in jackets, windbreakers, and other outerwear to provide consumers with convenient tightness adjustment. Especially in the field of workwear, such as work clothes worn by auto mechanics and electricians, it is crucial to use Velcro to secure the cuffs. It can effectively prevent loose cuffs from being caught in tools or equipment, greatly ensuring the safety of workers.
[0004] However, this traditional Velcro fastening method suffers from several drawbacks: its adhesiveness weakens significantly with repeated use, it has limited dyeing options, and it can damage clothing fabrics or cause cuts, severely impacting product lifespan, production efficiency, and user experience. Therefore, there is an urgent need in this field for an innovative pull-tab adjustment mechanism that overcomes these shortcomings of Velcro, offering more stable fastening, a longer lifespan, a simplified manufacturing process, and a safer, more comfortable user experience, thereby driving a comprehensive improvement in the quality of apparel products. Utility Model Content
[0005] This invention provides an adjustable pull loop to solve the problems of short service life, low production efficiency, and poor user experience of existing pull loops.
[0006] To achieve the purpose of this utility model, an adjustable pull tab is provided. The pull tab includes an adjusting belt and a limiting member slidably connected to the adjusting belt. The adjusting belt is a strip-shaped body, with one end fixed to the fabric and the other end being a free end. Multiple evenly spaced adjusting posts are provided along the length direction of the adjusting belt, and a notch is formed between the ends of two adjacent adjusting posts. The limiting member is fixed to another fabric and has a through hole for the free end of the adjusting belt to pass through. A limiting post is provided on the inner wall of the through hole. When the adjusting belt passes through the through hole of the limiting member and slides along its length direction, the limiting post can be elastically engaged in the notch.
[0007] Furthermore, the adjusting belt is made of a plastic material and includes an integrally formed fixing part, adjusting part and handle part. The fixing part is fixed to the fabric, the adjusting part is connected to the fixing part, the adjusting post is provided on the adjusting part, and the handle part is located at the free end of the adjusting part.
[0008] Furthermore, the fixing part is glued, heat-pressed, or sewn onto the fabric.
[0009] In some embodiments, the adjusting post is disposed on the upper surface of the adjusting belt, and the adjusting post has protrusions at both ends along the width direction of the adjusting belt. The protrusions are located outside the two ends along the width direction of the adjusting belt, and the notch is formed between two adjacent protrusions.
[0010] In other embodiments, the adjusting post is disposed on the upper and lower surfaces of the adjusting belt, and the two ends of the adjusting post along the width direction of the adjusting belt are respectively provided with protrusions. The protrusions are located outside the two ends of the adjusting belt in the width direction, and the notch is formed between two adjacent protrusions.
[0011] Preferably, the length of the protrusion along the width direction of the adjustment belt is 1~2 mm, and the height of the protrusion along the thickness direction of the adjustment belt is 0.8~1.5 mm.
[0012] The limiting member is made of plastic material and includes a connecting part and a limiting ring disposed on the connecting part. The limiting ring and the connecting part form the through hole, and the limiting post is disposed on the inner walls of both sides of the through hole.
[0013] Furthermore, the limiting ring is a rectangular ring, the through hole is a rectangular hole, and the two limiting posts protrude into the inside of the through hole to form a channel for the free end of the adjusting belt to slide.
[0014] Preferably, the length of the limiting post along the sliding direction of the adjusting belt is 1.5~2.5 mm, and its width corresponds to the length of the notch.
[0015] Furthermore, the connecting part is adhered to or sewn onto the other fabric, and the upper surface of the connecting part is provided with a groove, with the bottom of the limiting ring located within the groove.
[0016] The beneficial effects of this utility model are as follows: 1) By cooperating with the adjusting belt and the limiting component, the limiting post is locked in the gap between two adjacent adjusting belts, thus achieving physical interference locking. This not only makes the operation simple and smooth with a good user experience, but also ensures reliable locking and a long service life.
[0017] 2) By using elastic plastic adjustment bands and limiting parts, the surface is smooth, which improves the user's wearing comfort and safety, and is easy to clean and maintain. It effectively solves the problems of traditional Velcro getting dirty easily and injection molded parts turning white after long-term use, so that the pull tab can maintain a clean and new appearance for a long time.
[0018] 3) The pull tab of this utility model can adjust the tightness of clothing according to the user's needs, and is suitable for different types of clothing. It has a wide range of applications and good market application prospects. Attached Figure Description

Detailed Implementation
[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and specific embodiments. 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.
[0025] Please see Figure 1 This utility model provides an adjustable pull tab, which is installed on clothing fabric. The pull tab includes an adjusting band 10 and a limiting member 20. By sliding and fixing the adjusting band 10 within the limiting member 20, the size of the clothing can be easily adjusted, effectively meeting the user's needs for different levels of tightness. This pull tab can be used to adjust the cuffs, shoulder width, and waist circumference of clothing, etc. This embodiment uses adjusting the cuffs as an example for explanation.
[0026] like Figure 1 , Figure 2As shown, the adjustment band 10 is located on the fabric. When used to adjust the size of the cuff, the adjustment band 10 is located on the outer side of the cuff end. The adjustment band 10 is made of an elastic and durable plastic material. In this embodiment, the adjustment band 10 is made of silicone material, which is not only chemically stable and not easily oxidized or discolored by ultraviolet radiation or frequent use, thus maintaining its appearance even after long-term use, but also has a soft and skin-friendly feel, avoiding the friction and discomfort that may be caused by traditional Velcro or hard plastic. The adjustment band 10 has a fixed end and a free end, specifically, as shown... Figure 2 As shown, it includes an integrally formed fixing part 11, adjusting part 12, and handle part 13. The integral molding simplifies the production process, improves waterproofness and overall strength, and facilitates cleaning. The fixing part 11 is the foundation for connecting the adjusting band 10 to the cuff. It is fixed to the outer side of the cuff end by means of adhesive, heat pressing, or sewing, or other reliable fixing methods. An adjusting part 12 is provided at one end of the fixing part 11, which is a key component for adjusting the cuff tightness. Multiple evenly spaced adjusting posts 121 are provided along the length of the adjusting part 12, and a notch 123 is formed between the ends of two adjacent adjusting posts 121. In some embodiments, the adjusting posts 121 are located on the upper surface of the adjusting band 10, and protrusions 122 are provided at both ends of the adjusting post 121 along the width direction of the adjusting band. These protrusions 122 are located on the outer sides of both ends of the adjusting band 10 in the width direction, and a notch 123 is formed between two adjacent protrusions 122. A handle 13 is located at the free end of the adjustment section 12 away from the fixed section 11. This handle 13 is used by the user to pull the adjustment band 10 to move it along its length. It can be configured with a triangular structure at the end to improve the user experience. Finger positioning grooves (not shown in the figure) or other similar structures can also be provided on the handle 13 to provide sufficient friction for the user even when the surface is wet or slippery or when wearing gloves, ensuring the convenience and reliability of the adjustment operation.
[0027] In such Figure 2 In the illustrated embodiment, the adjustment post 121 can be disposed on the upper and lower surfaces of the adjustment band 10. By providing the adjustment post 121 on both sides, it not only prevents the adjustment band 10 from shifting or loosening due to unilateral force, but is also particularly suitable for scenarios such as workwear cuffs requiring frequent movement, ensuring that the fixing effect does not diminish with increased use. Furthermore, by providing protrusions 122 at both ends of the adjustment post 121, the compressive force during adjustment can be dispersed, reducing deformation and breakage problems caused by long-term stress concentration on one side of the structure, while also reducing fatigue wear on the silicone material and extending the overall service life of the product. In addition, when the cuff of the garment requires bidirectional adjustment (such as adaptation for different activity postures), the protrusions 122 on both sides ensure that the adjustment band 10 maintains stable guidance during sliding, thereby avoiding possible jamming or shifting of the unilateral structure.
[0028] like Figure 1 , Figure 3 As shown, to achieve reliable locking and convenient adjustment of the adjustment strap 10, a limiting member 20 is provided on another fabric. When used to adjust the cuff size, the limiting member 20 is provided on the outer side of the cuff end. This limiting member 20 is spaced apart from the fixing part 11 of the adjustment strap 10, and their relative positions on the cuff are such that when the user pulls the adjustment strap 10 to wrap around the cuff, the outermost adjusting posts 121 at both ends of the adjusting part 12 can form an effective connection with the limiting member 20. This design ensures that the cuff can achieve both the most comfortable fit in the loosest state and the most secure protection in the tightest state, maximizing the adjustment range and adapting to a wider range of users and usage scenarios.
[0029] Specifically, such as Figure 3 As shown, the limiting member 20 is also integrally molded from a highly elastic plastic material. In a preferred embodiment of this utility model, the limiting member 20 is made of silicone material, giving it the same characteristics as the adjusting band 10: resistance to discoloration, soft touch, and skin-friendly comfort, ensuring a uniform overall feel at the cuff. The limiting member 20 includes a connecting part 21 and a limiting ring 22. The connecting part 21 is a rectangular block, and its lower surface is fixed to the outer side of the cuff end by adhesive, heat pressing, or sewing, thus providing a stable support base. A groove 211 is provided on the upper surface of the connecting part 21, and the limiting ring 22 is disposed within the groove 211. Figure 3 As shown, the limiting ring 22 is a rectangular ring with its bottom located within the groove 211. A through hole 222 is formed between the limiting ring 22 and the connecting part 21. This through hole 222 is a rectangular hole for the adjusting belt 10 to pass through. Limiting posts 221 are respectively provided on the inner walls of both sides of the through hole 222. These two opposing limiting posts 221 protrude inward, forming a narrow channel 223. The limiting posts 221 cooperate with the notch 122. When the cuff size needs to be adjusted, the adjusting belt 10 is passed through the through hole 222 and slid within the channel 223. When the adjustment is complete, the limiting post 221 engages with the notch 122, locking the adjusting belt 10 and the limiting member 20.
[0030] To ensure a good locking effect and operational feel between the adjusting band 10 and the limiting member 20, the dimensions of the protrusion 122 and the limiting post 221 have been optimized in this embodiment. Specifically, the length of the protrusion 122 on the adjusting part 12 along the width direction of the adjusting band 10 is 1~2 mm. This size range ensures that the protrusion 122 has sufficient structural strength to form effective mechanical interference with the limiting post 221, preventing accidental disengagement. At the same time, it also avoids structural bulkiness due to excessive protrusion or unnecessary friction to the user. Meanwhile, the height of the protrusion 122 along the thickness direction of the adjusting band 10 is set to 0.8~1.5 mm. This height range allows for a sufficiently deep notch 123 between two adjacent adjusting posts 121, providing a clear engagement space for the limiting post 221. The moderate height ensures that the limiting post 221 can smoothly slide into and out of the notch 123, and also ensures that there is sufficient contact surface between the limiting post 221 and the bottom of the notch 123 in the locked state, thereby providing a stable locking force. The length of the limiting post 221 along the sliding direction of the adjusting band 10 is set to 1.5~2.5 mm, so that the limiting post 221 has sufficient contact area to interact with the adjusting post 121 and the notch 123. This allows it to withstand the reverse tension from the adjusting band when locked, ensuring the reliability of the locking and avoiding increased wear or structural failure due to excessive size. The height of the limiting post 221 corresponds to the width of the notch 123. Specifically, the height of the limiting post 221 should be slightly less than or equal to the width of the notch 123 to ensure that the limiting post 221 can smoothly and accurately engage or disengage from the notch 123 during adjustment, achieving a clear sense of gear position and a smooth adjustment experience.
[0031] like Figure 1 , Figure 4As shown, the working process of the adjustable pull tab in this embodiment is as follows: When the user needs to tighten the cuff, the user pulls the adjusting strap 10 through the through hole 222 of the limiting ring 22 via the handle 13, allowing the adjusting strap 10 to slide within the through hole 222. When the outermost adjusting post 121 of the adjusting strap 10 slides to the limiting post 221 within the limiting ring 22, the adjusting post 121 needs to be squeezed and pass through the channel 223 formed by the limiting posts 221 on both sides. When the cuff reaches the desired tightness, the user stops pulling the handle 13. Since the limiting member 20 itself is made of elastic silicone, the limiting post 221 will undergo slight elastic deformation when squeezed, allowing the adjusting post 121 to pass through. Once the adjusting post 121 has passed through, the limiting post 221 quickly returns to its original position under the action of elastic restoring force. At this time, if the user wants to pull the adjusting strap 10 back in the opposite direction, the protrusions 122 at both ends of the adjusting post 121 will form mechanical interference with the limiting post 221. Specifically, the limiting post 221 will engage with the notch 123 between the ends of two adjacent adjusting posts 121, thereby effectively preventing the adjusting band 10 from sliding out in the opposite direction and achieving a secure lock. When the user needs to loosen the cuff, he / she needs to actively apply a slightly larger pulling force to make the adjusting post 121 elastically squeeze past the limiting post 221 again.
[0032] In summary, this embodiment achieves physical interference locking by cooperating the adjusting band 10 with the limiting member 20, allowing the limiting post 221 to engage within the notch 123 between the ends of two adjacent adjusting bands 10. This not only provides a simple and smooth operation and a good user experience but also ensures reliable locking and a long service life. Furthermore, by using plastic adjusting bands 10 and limiting members 20, their smooth surfaces enhance user comfort and safety, and facilitate cleaning and maintenance. This effectively solves the problems of traditional Velcro being easily soiled and injection-molded parts turning white over time, allowing the zipper to maintain a clean and new appearance for a long time. In addition, the zipper of this invention allows for adjustment of tightness in different parts of clothing according to user needs, making it suitable for different groups and types of clothing, with a wide range of applications and good market prospects.
