Description

Technical Field

[0001] The utility model relates to the field of zipper accessory products, and particularly relates to a magnetic pull tab. Background Art

[0002] The pull tab of a zipper is usually formed by a metal sheet with an orifice, and the zipper head is installed in the orifice. 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. For example, the structure shown in Chinese Patent CN2415646Y, a rope-type zipper handle, is composed of a pull rope and a handle body. The handle body is a two-color flat body with a concave middle part, and convex strips are provided at the upper and lower parts of the concave part. The pull rope is fixed to the upper part of the handle body. It shows the basic structure of the existing pull tab with a pull rope; and currently, for the pull tab structure composed of a pull rope and a handle body, the pull rope will swing with the movement of the human body, affecting the positioning of the pull tab when the zipper is pulled; therefore, there is also a technical solution in the market such as the one with the Chinese Patent Publication No. CN 216853979 U, a non-slip pull tab for nylon zippers. Its structure includes a pull tab and a perforation. The top of the pull tab is provided with a perforation. The pull tab includes a fixed piece and a movable piece. The movable piece is installed at the bottom of the fixed piece. A through hole is provided in the middle of the bottom of the fixed piece. A sliding groove is provided on the side of the middle of the through hole. The top of the through hole is communicated with the bottom of the installation groove provided in the fixed piece. A nut is connected to the bottom of the installation groove. The middle of the top of the movable piece is connected with a screw rod. The top of the screw rod is connected with a rod head. A slider is connected to the side of the lower part of the screw rod. The screw rod passes through the through hole and is threadedly connected with the nut. The rod head is arranged in the installation groove. The slider is arranged in the sliding groove. The two ends of the sliding groove are respectively embedded with a first magnet and a second magnet.

[0003] The above technical solution uses the form of embedding magnets in the pull tab to make the pull tab have a magnetic attraction effect; however, the pull tab of this structure is too complex, not only the production process is cumbersome, but also the cost is relatively high. Summary of the Utility Model

[0004] Therefore, the utility model provides a magnetic pull tab, which solves the problem that the existing pull tab with a magnetic attraction effect has a relatively high cost.

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

[0006] A magnetic pull tab includes a pull rope and a pull tab body formed by injection molding. The pull rope has a first rope end and a second rope end. The first rope end and the second rope end are embedded and fixed in the body. The pull tab body includes an outer shell and a magnet located at the center of the outer shell. The magnet is concentrically arranged with the outer shell. The outer shell is composed of a first shell and a second shell which are sequentially injection molded. The first rope end and the second rope end extend inward from the center of the outer shell and are embedded and fixed.

[0007] Preferably, both the outer housing and the magnet are cylindrical. The first rope end and the second rope end extend to the center of the magnet, and a connecting portion located at the center of the outer housing is formed between the first rope end, the second rope end and the outer housing.

[0008] Preferably, the magnet is a hollow cylinder, and the first rope end and the second rope end extend into the magnet.

[0009] Preferably, the outer housing has a regular polyhedron structure.

[0010] Preferably, the outer housing has an irregular polyhedron structure.

[0011] Preferably, the first rope end and the second rope end located outside the outer housing have a suture portion.

[0012] Preferably, the suture portion is wavy.

[0013] Preferably, the suture portion extends into the outer housing.

[0014] Preferably, the color of the suture portion is different from that of the drawstring.

[0015] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0016] This technical solution improves the traditional pull tab with a magnetic attraction function. In terms of structure, a magnet is embedded in an injection-molded outer housing. In terms of appearance, it has the same feel as the traditional injection-molded pull tab. The magnet is located at the center of the outer housing, ensuring the overall weight distribution of the pull tab and the consistent feel when pulling during use. Moreover, the first rope end and the second rope end of the drawstring are directly involved in the injection molding of the outer housing, forming a good connection structure between the drawstring and the outer housing, ensuring the structural strength of the pull tab. The outer housing is still injection-molded during production, which not only simplifies the cumbersome process of installing the magnet in the traditional way, greatly improves the production efficiency, but also correspondingly reduces the cost of the pull tab, and better meets the production and market requirements.

[0022] The following will combine specific embodiments to elaborate in detail on the implementation mode of the present utility model, so as to fully understand how the present utility model uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0023] Embodiment 1

[0024] Reference Figure 1 and Figure 2 , a magnetic attraction pull tab, including a drawstring 1 and an injection-molded pull tab body. The drawstring 1 has a first rope end 11 and a second rope end 12, and the first rope end 11 and the second rope end 12 are embedded and fixed in the pull tab body. Here, the first rope end 11 and the second rope end 12 not only include the two end portions of the drawstring 1, but also refer to the end portions of the drawstring 1 and a portion with a certain length near the end portions;

[0025] Among them, the pull tab body includes an outer housing 2 and a magnet 3 located at the center of the outer housing 2. The magnet 3 is concentrically arranged with the outer housing 2. The outer housing 2 is composed of a first housing 21 and a second housing 22 formed by sequential injection molding. The sequential injection molding here means that after the first housing 21 is pre-formed, the injection molding process of the second housing 22 is carried out;

[0026] The first rope end 11 and the second rope end 12 extend inward from the center of the outer housing 2 and are embedded and fixed, so that the connection position between the drawstring 1 and the outer housing 2 is located at the center position of the outer housing 2. After being installed on the zipper, it can ensure that the position of the pull tab meets the shape requirements and will not shift. This technical solution improves the traditional pull tab with magnetic attraction function. Structurally, an outer housing 2 formed by injection molding is embedded with a magnet 3. In terms of appearance, it has the same feel as the traditional injection-molded pull tab. The magnet 3 is located at the center position of the outer housing 2, ensuring the overall weight distribution of the pull tab and the consistent feel when pulling during use; moreover, the first rope end 11 and the second rope end 12 of the drawstring 1 are directly involved in the injection molding of the outer housing 2, forming a good connection structure between the drawstring 1 and the outer housing 2, ensuring the structural strength of the pull tab. In production, the outer housing 2 is still formed by injection molding, which not only simplifies the cumbersome process of installing the magnet 3 in the traditional way, greatly improves the production efficiency, but also correspondingly reduces the cost of the pull tab, and can better meet the production and market requirements.

[0027] Structurally as Figure 2As shown, both the outer housing 2 and the magnet 3 are cylindrical. The first rope end 11 and the second rope end 12 extend to the center of the magnet 3, and a connecting portion 23 located at the center of the outer housing 2 is formed between the first rope end 11, the second rope end 12 and the outer housing 2.

[0028] On this basis, in order to increase the connection strength between the pull rope 1 and the pull tab, it can also be as Figure 3 shown, make the magnet 3 a hollow cylinder, and the first rope end 11 and the second rope end 12 extend to the inside of the magnet 3; in this way, the size and coverage range of the connecting portion 23 are increased to obtain greater structural strength.

[0029] In this embodiment, only a cylindrical pull tab structure is taken as an example. Under this basic structure, the outer housing 2 can be a regular polyhedron structure or an irregular polyhedron structure. According to different shape design requirements, different shaped molds can be used for production to obtain more diverse products.

[0030] Embodiment 2

[0031] Referring to Figure 4 , compared with Embodiment 1, the first rope end 11 and the second rope end 12 located outside the outer housing 2 have a suture portion 4. Here, the suture portion 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 into a whole, and can further improve the structural strength.

[0032] In terms of structure, different suture portion 4 structures can be set according to requirements. The suture portion 4 is wavy and can be of a different color from the pull rope 11 to obtain a more diverse appearance;

[0033] Moreover, when the length of the pull rope 1 is sufficient and the suture portion 4 is produced before the knot portion in production, the suture portion 4 can extend into the outer housing 2, which can further increase the structural strength of this connection position, also connect the first rope end 11 and the second rope end 12, reduce the occurrence of the situation that the position of the pull rope 1 deviates during injection molding, and ensure the structural strength while taking into account the yield rate of production.

[0034] 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 form and detail without departing from the spirit and scope of the present invention as defined by the appended claims, and all such changes are within the protection scope of the present invention.
