Description

Technical Field

[0001] This utility model relates to the field of zipper accessories, specifically to a sliding rope adjustable pull tab assembly. Background Technology

[0002] A plastic pull tab with a drawstring on a zipper is a component that combines functional design with practicality, commonly found in clothing, bags, and outdoor gear. It consists of a plastic pull tab body and a drawstring. The plastic pull tab body is typically made of lightweight plastics such as polypropylene (PP), polyethylene (PE), or ABS, which are corrosion-resistant, wear-resistant, and low-cost. Its shape is often flat, oval, or ring-shaped, and the surface may have textures or brand logos to enhance grip. The connection is achieved by injection molding directly to the top of the zipper slider (zipper head), ensuring synchronized movement during operation. The drawstring is commonly made of nylon, polyester, or elastic cord, possessing high strength and tensile strength. This structure offers multiple advantages, including improved usability, anti-slip properties, enhanced aesthetics, and high durability, and is now widely used in clothing, bags, outdoor gear, and industrial products.

[0003] Its basic structure is shown in the technical solution with authorization announcement number CN 103476291 B, which proposes a single-piece zipper pull tab, including: a molded elastic pull tab body; and a molded cord defining a loop integrally formed with the pull tab body, the cord having a length extending from the pull tab body.

[0004] Under the current structure, the design of the pull tab and pull cord needs to take into account factors such as ease of use. However, when the pull cord is designed to be too long, problems such as difficulty for consumers to grasp, easy movement of the pull tab as a whole, and inconvenience in tidying up will occur. Summary of the Invention

[0005] Therefore, this utility model provides a sliding rope adjustable pull tab assembly, which solves the problem of reduced usability of current long rope pull tab structures.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A sliding rope adjustable pull tab assembly includes:

[0008] A pull rope, the pull rope having a first rope end and a second rope end;

[0009] A fixed pull tab body has a base located at the center and wings extending from the base to both sides. The first rope end and the second rope end are respectively embedded and fixed in the wings at both ends so that the pull rope between the first rope end and the second rope end forms a rope loop.

[0010] The movable pull tab is a hollow structure with a through channel. The rope loop is inserted into the through channel so that the movable pull tab can be movably sleeved on the rope loop. The rope loop is divided into a handle loop that fixes the pull tab and the movable pull tab, and a connecting loop located at the free end of the rope loop.

[0011] Preferably, the movable pull tab body is provided with a plurality of through grooves that communicate with the through channel, and the rope loop portion can be shown from each of the through grooves.

[0012] Preferably, the two wings are symmetrically distributed and tilted toward one side of the movable pull tab body.

[0013] Preferably, the movable pull tab is a rectangular block structure, and the through channel extends along its long end.

[0014] Preferably, the base surface is provided with anti-slip protrusions.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] The sliding rope adjustable pull tab assembly proposed in this technical solution achieves multiple technical advantages through the collaborative design of the fixed pull tab body and the movable pull tab body. The fixed pull tab body adopts a symmetrical structure with a central base and two side wings. The first rope end and the second rope end are respectively embedded and fixed in the wings. The rigid connection between the wings and the base disperses the force on the pull rope, avoids local stress concentration, significantly improves the load-bearing strength of the handle ring, and has high structural stability. The movable pull tab body is sleeved on the rope ring through a through channel. The length ratio of the handle ring and the connecting ring can be freely adjusted by sliding adjustment. It can not only adapt to the ring size requirements of different usage scenarios (such as hand carrying, hanging, or binding), but also achieve quick positioning through the relative position of the fixed pull tab body and the movable pull tab body, which is highly flexible. The rope ring is directly formed by embedding the two ends of the pull rope without additional connecting parts, which simplifies the assembly process and reduces the failure rate. Moreover, the handle ring and the connecting ring are continuous structures of the same rope, avoiding the strength loss caused by traditional sewing or knotting processes.

Detailed Implementation

[0019] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example

[0020] refer to Figure 1 A sliding rope adjustable pull tab assembly includes:

[0021] A pull rope 100, the pull rope 100 having a first rope end 101 and a second rope end 102;

[0022] A fixed pull tab body 200 has a base 200a located at the center and wings 200b extending from the base 200a to both sides. The first rope end 101 and the second rope end 102 are respectively embedded and fixed in the wings 200b at both ends, so that the pull rope 100 between the first rope end 101 and the second rope end 102 forms a rope loop 103. In this embodiment, the wings 200b on both sides are symmetrically distributed with an inclination towards one side of the movable pull tab body 300, which is more in line with ergonomic design. The inclination wings 200b form a natural finger-wrapping space, and the fingers can naturally fit the inclined surface of the wings 200b when grasping, avoiding rope slippage and improving grasping stability. The symmetrically distributed wings 200b make the pulling force evenly distributed to both ends of the pull rope 100, reducing the risk of rope twisting or deformation of the fixed pull tab body 200 caused by unilateral force, so that the pull tab has uniform force.

[0023] The movable pull tab body 300 is a hollow structure with a through channel 301. A rope loop portion 103 passes through the through channel 301, allowing the movable pull tab body 300 to be movably fitted onto the rope loop portion 103. The rope loop portion 103 is divided into a handle loop portion 103a that fixes the pull tab body 200 and the movable pull tab body 300, and a connecting loop portion 103b located at the free end of the rope loop portion 103. Structurally, the movable pull tab body 300 is a rectangular block structure, with the through channel 301 extending along its long end. The length of the movable pull tab body 300 is designed to be 15%-25% of the circumference of the rope loop portion 103, ensuring sufficient contact area between the through channel 301 and the rope loop portion 103 while retaining ample adjustment space. This proportion avoids both slippage and loss of control caused by an excessively short covering of the movable pull tab 300, and excessive length that limits the adjustment range of the handle ring 103a, achieving a precise balance between "adjustability" and "stability." Simultaneously, the block structure increases its weight, and combined with the frictional resistance of the through channel 301 and the rope ring 103, this generates greater static friction when the movable pull tab 300 is under force on the handle ring 103a. Even under external pulling force, the movable pull tab 300 maintains a relatively fixed position, preventing unexpected changes in ring size due to slippage and significantly improving reliability.

[0024] The sliding rope adjustable pull tab assembly proposed in this technical solution achieves multiple technical advantages through the coordinated design of the fixed pull tab body 200 and the movable pull tab body 300. The fixed pull tab body 200 adopts a symmetrical structure of a central base 200a and two side wings 200b. The first rope end 101 and the second rope end 102 are respectively embedded and fixed in the wings 200b. The rigid connection between the wings 200b and the base 200a is used to distribute the force on the pull rope 100, avoid local stress concentration, significantly improve the load-bearing strength of the handle ring 103a, and achieve high structural stability. The movable pull tab body 300 is sleeved on the rope through the through channel 301. The length ratio of the handle loop 103a to the connecting loop 103b can be freely adjusted by sliding adjustment, which can not only adapt to the needs of different usage scenarios (such as hand carrying, hanging or binding) for the size of the loop, but also achieve quick positioning by fixing the relative position of the pull tab 200 and the movable pull tab 300, which is highly flexible. The rope loop 103 is directly formed by embedding the two ends of the pull rope 100 without the need for additional connecting parts, which simplifies the assembly process and reduces the failure rate. Moreover, the handle loop 103a and the connecting loop 103b are continuous structures of the same rope, avoiding the strength loss caused by traditional sewing or knotting processes.

[0025] In this embodiment, the movable pull tab body 300 is provided with a plurality of through grooves 302 that communicate with the through channel 301, and the rope loop portion 103 can be seen from each of the through grooves 302. The structure of the through grooves 302 has a dual optimization effect. First, it enhances friction. The through grooves 302 communicate with the through channel 301, making the rope loop portion 103 partially exposed, increasing the contact when the finger pulls the pull tab, increasing the frictional resistance during sliding adjustment, and preventing slippage. Second, it provides tactile feedback. The user can directly perceive the positional change of the rope loop portion 103 through the through grooves 302. Combined with the sliding resistance of the movable pull tab body 300, it forms a clear tactile feedback, which facilitates precise control of the adjustment range.

[0026] In this embodiment, the surface of the base 200a is provided with anti-slip protrusions 201. The anti-slip protrusions 201 increase the contact friction between the fingers and the fixed pull tab 200, especially in wet or fast-operation scenarios, significantly reducing the risk of slipping and playing an anti-slip role; at the same time, the anti-slip protrusions 201 can be designed as brand logos, functional symbols or decorative patterns, which not only enhances product recognition, but also enhances the visual sense of layering through three-dimensional structure, taking into account both practicality and aesthetics.

[0027] In summary, this component achieves a high-efficiency balance between strength, adjustability, ease of use, and aesthetics through structural innovation and detailed optimization, making it suitable for rope adjustment needs in various fields such as bags, sports equipment, and pet supplies.
