Description

Technical Field

[0001] The utility model relates to the field of zipper accessory products, in particular to a heat shrinkable knot pull tab. Background Art

[0002] The pull tab of a zipper is usually formed by a metal sheet with an aperture, in which the zipper head is installed. These metal sheets are often too small to allow the zipper to slide easily; therefore, many manufacturers attach a rope with a larger handle to the end of the existing zipper handle, such as the structure shown in Chinese patent CN2415646Y, a rope-type zipper handle, which is composed of a rope and a handle body. The handle body is a two-color flat body with a concave middle part. There are convex strips at the upper and lower parts of the concave part, and the rope is fixed to the upper part of the handle body. It shows the basic structure of the existing pull tab with a rope.

[0003] However, the current pull tab structure with a drawstring cannot combine practicality, aesthetics and personalization, and is difficult to meet the growing market demand. Utility Model Content

[0004] Therefore, the utility model provides a heat shrinkable rope knot pull tab, which solves the problem that practicality and personalization cannot be taken into account at the same time.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] A heat shrinkable rope knot pull tab comprises a draw rope and an injection molded rope knot portion, wherein the draw rope has a first rope end and a second rope end, the rope knot portion is sleeved on the first rope end and the second rope end to connect the two to each other, a heat shrinkable tube is sleeved on the outer surfaces of the rope knot portion and the first rope end and the second rope end, and the heat shrinkable tube is attached to the rope knot portion and the contact ends of the first rope end and the second rope end.

[0007] Preferably, the knot portion has an extension portion away from one side of the first rope end and the second rope end, the extension portion and the knot portion are integrally formed, and the first rope end and the second rope end extend to the extension portion.

[0008] Preferably, the extension portion extends out of the heat shrink tube.

[0009] Preferably, the first rope end and the second rope end located outside the heat shrink tube have a suture portion.

[0010] Preferably, the suture portion is wavy.

[0011] Preferably, the suture portion extends into the heat shrink tube.

[0012] Preferably, the suture portion and the drawstring have different colors.

[0013] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0014] In this technical solution, an injection-molded knot part is used to simulate a traditional knot. During production, both ends of the pull rope are formed along with the knot part. Then, the pull rope and the knot part are fixed by a heat-shrinkable tube on the outer layer. By using a traditional production process to simulate the knot formed by tying a traditional pull rope, it not only has a very personalized appearance, but also simplifies the production difficulty compared with the traditional pull rope knotting and forming, ensuring the consistency of the produced pull tabs; the external heat-shrinkable tube provides structural protection for the pull rope and the knot part, thereby ensuring the structural strength of the pull tab, and the external shape parameters such as the color of the heat-shrinkable tube can also be adjusted according to requirements to obtain more diverse products and better meet the current market demand.

[0019] The following will specifically describe the embodiments of the present utility model in detail, so as to fully understand how the present utility model uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0020] Embodiment 1

[0021] Refer to Figure 1 and Figure 2 , a heat-shrinkable knot pull tab, comprising a pull rope 1 and an injection-molded knot part 2. The pull rope 1 has a first rope end 11 and a second rope end 12. Here, the first rope end 11 and the second rope end 12 not only include the two end portions of the pull rope 1, but also refer to the end portions of the pull rope 1 and a part with a certain length near the end portions;

[0022] The knot part 2 is sleeved on the first rope end 11 and the second rope end 12 to connect the two, and the ends of the first rope end 11 and the second rope end 12 are embedded in the knot part 2; a heat shrinkable tube 3 is sleeved on the outer surfaces of the knot part 2, the first rope end 11 and the second rope end 12, and the heat shrinkable tube 3 fits on the knot part 2 and the contact ends of the first rope end 11 and the second rope end 12; the contact ends here refer to the side where the first rope end 11 and the second rope end 12 are close to each other after being injection-molded into the knot part 2. It is necessary to ensure that the heat shrinkable tube 3 covers this position and the covered range has a certain length to prevent the first rope end 11 and the second rope end 12 from detaching from the knot part 2 when stressed, thereby ensuring the structural strength. In this technical solution, the knot part 2 formed by injection molding simulates a traditional knot. During production, both ends of the pull rope 1 are formed along with the knot part 2, and then the pull rope 1 and the knot part 2 are fixed by the outer heat shrinkable tube 3. By using the traditional production process to simulate the knot formed by tying the traditional pull rope 1, it not only has a very unique appearance, but also simplifies the production difficulty compared with the traditional tying of the pull rope 1 to ensure the consistency of the produced pull tabs; externally, the heat shrinkable tube 3 protects the structure of the pull rope 1 and the knot part 2, thereby ensuring the structural strength of the pull tab, and the external shape parameters such as the color of the heat shrinkable tube 3 can also be adjusted according to requirements to obtain more diverse products and better meet the current market demand. At the same time, by using the heat shrinkable tube 3 to wrap, compared with the knot formed by tying the traditional pull rope 1, it has a more gentle hand feeling and improves the comfort when using the pull tab.

[0023] Structurally, the knot part 2 has an extension part 21 on the side away from the first rope end 11 and the second rope end 12. The extension part 21 is integrally formed with the knot part 2, and the first rope end 11 and the second rope end 12 extend to the extension part 21. Among them, the extension part 21 is in the shape of a regular rectangular block; Figure 1 In the structure shown, the entire extension part 21 is covered by the heat shrinkable tube 3; during production, the extension part 21 can also extend out of the heat shrinkable tube 3 according to requirements, and the external shape of the extension part 21 can be adjusted accordingly to obtain more diverse products.

[0024] Embodiment 2

[0025] Reference Figure 3 , compared with Embodiment 1, the first rope end 11 and the second rope end 12 located outside the heat shrinkable tube 3 have a suture part 4; here, the suture part 4 can increase the connection tightness between the first rope end 11 and the second rope end 12 on the basis of the structure of Embodiment 1, making the first rope end 11 and the second rope end 12 an integral whole, and further improving the structural strength.

[0026] Structurally, the structure of the suture part 4 can be set according to requirements. The suture part 4 is wavy and can be made of a color different from that of the drawstring 1 to obtain a more diverse appearance.

[0027] Moreover, when the length of the drawstring 1 is sufficient and the suture part 4 is produced prior to the knot part 2 during production, the suture part 4 can extend into the heat-shrinkable tube 3; thus, the appearance of the suture part 4 is also formed on the heat-shrinkable tube 3, which not only ensures the structural strength but also increases the elements on the outer surface of the heat-shrinkable tube 3.

[0028] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
