Description

Technical Field

[0001] This utility model relates to the field of zipper technology, specifically to a rope zipper with adjustable zipper length. Background Technology

[0002] A cord zipper pull is a functional accessory used in zippers, clothing, bags, and other items. It mainly consists of a zipper pull body and a connecting cord. By pulling the cord, the zipper can be opened and closed, the cord can be tightened or adjusted, etc. It combines practicality and decorative design. In existing technologies, the large opening can cause the side parts of the cord to spread outwards, and the upper part of the cord to run upwards, resulting in the cord falling off or becoming loose. However, a cord-preventing zipper pull with the announcement number CN221104994U uses a limiting groove and an inner hook to effectively prevent the cord from coming out of the zipper pull. The cross-sectional size of the limiting opening is smaller than the cross-sectional size of the cord, so the cord will not easily come out, restricting the cord's movement, preventing the cord from spreading outwards, and reducing the possibility of the cord coming off the zipper pull opening. After the cord is assembled with the zipper pull, the overall integrity is better, improving the quality of the entire zipper product.

[0003] While the above technology can prevent the rope from easily slipping out, it has the problem of limited limiting effect. When dealing with ropes of different diameters, it is necessary to open molds separately for ropes of different diameters, which increases production costs. In addition, the fixed-size limiting port can only limit ropes of a specific diameter. Utility Model Content

[0004] The purpose of this invention is to provide a rope puller with adjustable length to solve the problem mentioned in the background art that the rope pullers currently on the market have limited effectiveness in restricting the pulling of ropes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rope puller with adjustable pull head length, comprising a pull head base, a rotating component rotatably connected inside the pull head base, a connecting component movably abutting one side of the rotating component, a pull rope sleeved on one side of the connecting component, a cap connected to the side of the pull rope away from the connecting component, sliding rods slidably connected to both ends inside the connecting component, limit rods fixedly connected to one side of each of the two sliding rods, and the two limit rods slidably connected to both ends inside the connecting component, the two ends of the pull rope respectively passing through the two limit rods, a limit component for limiting the sliding rods inside the connecting component, and an adjustment component for adjusting the position of the connecting component inside the rotating component.

[0006] Preferably, the limiting component includes two pull rods that are slidably connected to both ends of the connector, and the two pull rods are slidably connected to the interior of two sliding rods, and cavities are provided at both ends of the connector.

[0007] Preferably, each of the two cavities is provided with a first elastic ball, the two pull rods are slidably connected inside the two first elastic balls, and one end of each of the two pull rods is provided with a limiting plate.

[0008] Preferably, both pull rods are provided with a connecting plate at the top, and both connecting plates are provided with a pull ring at the top.

[0009] Preferably, the adjustment component includes two sliding plates respectively disposed at both ends of one side of the connector, the two sliding plates being slidably connected to both ends inside the rotating component, and both ends inside the two sliding plates having a storage groove.

[0010] Preferably, each of the four storage slots is slidably connected to a limiting post, and a second elastic ball is provided between each of the four limiting posts and the four storage slots. The end of each of the four limiting posts away from the second elastic ball is arc-shaped.

[0011] Preferably, a row of limiting holes is provided at the top and bottom of both sides of the rotating component, and four limiting pins are slidably connected inside the limiting holes, and the shapes and specifications of the limiting pins and limiting holes are compatible.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By passing the pull cord through the connector and then pulling the cord, the connector is moved, thus moving the base of the pull head. The lever effect reduces the force required to pull, making it especially suitable for situations where gloves are worn, hands are wet, or joints are inconvenient. The pull cord can swing freely, allowing users to pull the pull head from any angle, solving the problem of traditional hard pull tabs being unable to be pulled due to limited space.

[0014] By setting the limiting components, the pull rope is limited and fixed, which can lock the pull rope in the preset position and prevent the pull rope from gradually slipping or excessively contracting or stretching due to vibration, pulling or long-term use. It can also complete the storage of the pull rope and shorten the overall straight length of the pull rope.

[0015] The adjustable components allow for adjustment of the distance between the connector and the rotating part, thereby adjusting the overall length of the zipper head. In winter or when used outdoors, extending the zipper head length can prevent hands from being obstructed by clothing, making it difficult to grip. Shortening the zipper head length allows it to fit into tight clothing, the inside of small backpacks, and other areas with limited space, preventing the zipper head from protruding and snagging on foreign objects.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: a rope puller with adjustable pull head length.

[0025] Example 1: To address the limited limiting effect of existing rope pullers on the pull rope 4, the following is disclosed: a puller base 1, with a rotating component 2 rotatably connected inside the puller base 1; a connecting component 3 movably abuts against one side of the rotating component 2; and a pull rope 4 (e.g., ...) is sleeved on one side of the connecting component 3. Figure 1 and Figure 2 As shown), the pull rope 4 is connected to a cap 5 on the side away from the connector 3. Sliding rods 6 are slidably connected to both ends inside the connector 3. Limiting rods 7 are fixedly connected to one side of each sliding rod 6, and the two limiting rods 7 are slidably connected to both ends inside the connector 3. The two ends of the pull rope 4 pass through the two limiting rods 7 respectively (as shown). Figure 1 and Figure 2 As shown), it is used to limit and fix the pull rope 4. The connecting part 3 is provided with a limiting component to limit the sliding rod 6. The limiting component includes two pull rods 8 that are slidably connected to both ends inside the connecting part 3. The two pull rods 8 are slidably connected to the two sliding rods 6. Both ends inside the connecting part 3 are provided with cavities (such as...). Figure 5As shown), each of the two cavities is provided with a first elastic ball 10, and the two pull rods 8 are slidably connected inside the two first elastic balls 10 respectively. One end of each of the two pull rods 8 is provided with a limiting plate 9, and the top of each of the two pull rods 8 is provided with a connecting plate, and the top of each of the two connecting plates is provided with a pull ring.

[0026] When it is necessary to adjust the straight length of the pull rope 4, the pull ring (e.g.) can be pulled. Figures 1-5 As shown), this causes the connecting plate and pull rod 8 to move, thereby moving the pull rod 8 away from the sliding rod 6 and causing the limiting plate 9 to squeeze the first elastic ball 10. Then, it pushes the sliding rod 6 and the limiting rod 7 away from the pull rope 4. The pull rope 4 is then adjusted so that it can be folded. After adjustment, the sliding rod 6 is moved again, causing the limiting rod 7 to move closer to the pull rope 4. The pulling force on the pull rod 8 is then released, and the pull rod 8 will reset under the action of the first elastic ball 10, thus returning to the inside of the sliding rod 6 and limiting the sliding rod 6. This allows the limiting rod 7 to limit and fix the pull rope 4 (as shown). Figure 1 and Figure 2 (As shown).

[0027] Example 2: Unlike Example 1, the adjustment component can adjust the overall length of the slider. It discloses that the rotating part 2 has an adjustment component inside for adjusting the position of the connecting part 3. The adjustment component includes two sliding plates 11 respectively disposed at both ends of one side of the connecting part 3 (e.g., Figure 4 and Figure 6 As shown), two sliding plates 11 are slidably connected to the two ends inside the rotating component 2. Each end of the two sliding plates 11 has a storage slot. Limiting pins 12 are slidably connected inside each of the four storage slots to limit the movement of the sliding plates 11. Second elastic balls 13 are provided between each of the four limiting pins 12 and the four storage slots. The ends of the four limiting pins 12 away from the second elastic balls 13 are all arc-shaped. A row of limiting holes 14 (as shown) are provided at the top and bottom of both sides of the rotating component 2. Figures 1-4 and Figure 6 As shown, the four limiting pins 12 are slidably connected inside the limiting holes 14, and the shapes and specifications of the limiting pins 12 and the limiting holes 14 are compatible.

[0028] When it is necessary to adjust the length of the slider, the limit pin 12 can be pressed (e.g., Figures 1-4 and Figure 6 As shown), it compresses the second elastic ball 13 and moves it away from the limiting hole 14. Then, it pulls the connecting piece 3, causing the slide plate 11 to slide inside the rotating piece 2. After it moves to the appropriate position, the limiting pin 12 will enter the corresponding limiting hole 14 under the action of the second elastic ball 13, thereby limiting the slide plate 11.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
