Description

Technical Field

[0001] This utility model relates to zipper technology, and in particular to a magnetic zipper pull tab. Background Technology

[0002] Currently, zippers on the market consist of a zipper pull and a zipper belt. The zipper pull opens or closes the two rows of zipper belts, and most zipper pulls have a pull tab for the user to operate. Since the pull tab is usually located in a more conspicuous position than the zipper pull, its visual effect is particularly important for the entire zipper. Traditionally, the pull tab is fixed to the zipper pull after production and cannot be replaced according to the user's needs after purchase. Forcibly replacing it may damage the pull tab or the zipper pull. Therefore, most zippers have a relatively simple appearance and poor usability. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a magnetic pull tab with better performance.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A magnetic pull tab includes a pull tab body and a pull tab outer shell. The pull tab outer shell is detachably mounted on the pull tab body. At least one of the pull tab body and the pull tab outer shell is magnetic. The pull tab body and the pull tab outer shell attract each other and move closer under the action of magnetic force. The pull tab outer shell has a receiving cavity. The pull tab body passes through the receiving cavity. A slot is provided on the outer surface of the pull tab body. A hook is provided in the receiving cavity. When the pull tab outer shell is sleeved on the pull tab body, the hook is engaged in the slot.

[0006] Furthermore, the slot is located away from the free end of the pull tab body.

[0007] Furthermore, a guide groove is provided on the outer side of the pull tab body. The guide groove is opened along the length direction of the pull tab body and is connected to the slot.

[0008] Furthermore, the card slot has an unlocking sidewall and an engaging sidewall.

[0009] Furthermore, the unlocking sidewall and the engaging sidewall are arranged opposite to each other, and the unlocking sidewall and the engaging sidewall are located at opposite ends of the length direction of the slot.

[0010] Furthermore, the engaging sidewall is closer to the free end of the pull tab body than the unlocking sidewall.

[0011] Furthermore, the angle between the unlocking sidewall and the bottom of the card slot is greater than 90 degrees.

[0012] Furthermore, the distance between the slot and the free end of the pull tab body is less than the depth of the receiving cavity.

[0013] With the above structure, the zipper proposed by this utility model has the following technical effects: the zipper pull outer shell is detachably set on the zipper pull body, and the user can replace the zipper pull outer shell with different appearances as needed, so that the zipper pull presents different visual appearance effects. The zipper pull body and the zipper pull outer shell attract each other and approach each other under the action of magnetic force. The magnetic design makes the installation of the zipper pull outer shell easier. The hook of the zipper pull outer shell is embedded in the slot of the zipper pull body, which can ensure the firmness of the connection between the zipper pull outer shell and the zipper pull body, and prevent the zipper pull outer shell from being directly torn off by excessive force during daily use.

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3The illustration shows a magnetic pull tab, comprising a pull tab body 1 and a pull tab outer shell 2. One end of the pull tab body 1 is used to connect to a pull head, and the other end of the pull head body is a free end. The pull tab outer shell 2 is detachably mounted on the pull tab body 1. At least one of the pull tab body 1 and the pull tab outer shell 2 is magnetic. Preferably, one of the pull tab body 1 or the pull tab outer shell 2 is made of plastic and the other is made of iron. The plastic pull tab body 1 or the pull tab outer shell 2 has a magnet embedded within it. As another option, one of the pull tab body 1 or the pull tab outer shell 2 can also be made of magnet material and the other of iron material. Furthermore, both the pull tab body 1 and the pull tab outer shell 2 can be made of magnetic material.

[0023] The pull tab body 1 and the pull tab outer shell 2 are attracted to each other and brought closer together under the action of magnetic force.

[0024] The pull tab body 1 is sheet-shaped or cylindrical, and the pull tab outer shell 2 has a receiving cavity 3. The shape of the receiving cavity 3 matches the pull tab body 1, and the pull tab body 1 passes through the receiving cavity 3. When the pull tab body 1 is sheet-shaped, the receiving cavity 3 is a flat rectangular cavity; when the pull tab body 1 is cylindrical, the receiving cavity 3 is a cylindrical cavity. In this embodiment, the former solution is adopted. A slot 4 is provided on the outer surface of the pull tab body 1. As a preferred solution, there is one slot 4, which is a square slot. Furthermore, the slot 4 has an unlocking guide sidewall 5 and an engaging sidewall 6. Furthermore, the unlocking sidewall 5 and the engaging sidewall 6 are arranged opposite to each other, and the unlocking sidewall 5 and the engaging sidewall 6 are located at opposite ends of the length direction of the slot 4. The engaging sidewall 6 is closer to the free end of the pull tab body 1 than the unlocking sidewall 5. Preferably, the angle between the engaging sidewall 6 and the bottom of the slot 4 is less than or equal to 90 degrees, and the angle between the unlocking sidewall 5 and the bottom of the slot 4 is greater than 90 degrees.

[0025] Furthermore, a guide groove 7 is provided on the outer side of the pull tab body 1. Furthermore, the slot 4 is located away from the free end of the pull tab body 1, and the depth of the guide groove 7 is less than the depth of the slot 4.

[0026] The guide groove 7 is opened along the length direction of the pull tab body 1, and the guide groove 7 is connected to the slot 4.

[0027] A latch 8 is provided inside the receiving cavity 3. The guide groove 7 and the latch 8 cooperate with each other. When the pull tab outer shell 2 slides on the pull tab body 1, as... Figure 4 As shown, the hook 8 is located in the guide groove 7. When the pull tab outer shell 2 is fixedly sleeved on the pull tab body 1, the hook 8 slides to the end of the guide groove 7 and further enters the slot 4, as shown. Figure 5 As shown, the final hook 8 is embedded in the slot 4. During the opening and closing of the zipper, the hook 8 abuts against the engaging side wall 6. When the angle between the engaging side wall 6 and the bottom of the slot 4 is less than or equal to 90 degrees, the hook 8 can be more firmly engaged in the slot 4.

[0028] When the pull tab housing 2 needs to be replaced, push the pull tab housing 2 away from the free end of the pull tab body 1, such as... Figure 6 As shown, the hook 8 contacts the unlocking side wall and gradually disengages from the slot 4 under the action of the unlocking side wall. At this time, by applying a little force to overcome the magnetic force between the pull tab outer shell 2 and the pull tab body 1, the pull tab outer shell 2 can be removed from the pull tab body 1.

[0029] As a preferred solution, the distance between the slot 4 and the free end of the pull tab body 1 is less than the depth of the receiving cavity 3. This design aims to ensure that when the hook 8 is engaged in the slot 4, there is a margin of space between the free end of the pull tab body 1 and the receiving cavity 3, which facilitates the replacement of the pull tab outer shell 2.

[0030] The present invention has the following advantages: the pull tab outer shell 2 is detachably mounted on the pull tab body 1, and the user can replace the pull tab outer shell 2 with different appearances as needed to make the pull tab present different visual effects. The pull tab body 1 and the pull tab outer shell 2 attract each other and approach each other under the action of magnetic force. The magnetic design makes the installation of the pull tab outer shell 2 easier. The hook 8 of the pull tab outer shell 2 is embedded in the slot 4 of the pull tab body 1, which can ensure the firmness of the connection between the pull tab outer shell and the pull tab body and prevent the pull tab outer shell from being directly pulled off by excessive force during daily use.
