Description

Technical Field

[0001] This utility model is a zipper with a snap-fit ​​pull tab, belonging to the field of zippers. Background Technology

[0002] A zipper is a connector that uses a series of teeth to join or separate items. It is now widely used in clothing, bags, tents, and other products.

[0003] To prevent the zipper pull from wobbling after use, existing zippers have a locking structure on the connector between the zipper pull and the zipper body. The connector engages with the zipper lug on the zipper body to limit the zipper pull's movement. To improve the connection strength, this connector is usually made of metal. Therefore, the zipper lug on the zipper body is prone to wear after frequent use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a zipper with an engaging pull tab. This solves the problem that existing zippers, in order to limit the swaying of the pull tab after use, have an engaging structure on the connector between the pull tab and the zipper body. The connector engages with the zipper lug on the zipper body to fix the pull tab in place, thereby limiting the swaying of the pull tab. To improve the connection strength, the connector is generally made of metal. Therefore, after frequent use, the zipper lug on the zipper body is prone to wear.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a zipper with a snap-fit ​​pull tab, the structure of which includes a zipper body, a pull nose, a connector, and a pull tab; the pull nose is vertically disposed on the front end face of the zipper body; the connector is movably fastened to the pull nose; the pull tab is connected to the bottom of the connector, and the top of the pull tab is provided with a snap-fit ​​element that penetrates the connector and elastically engages with the bottom end of the pull nose;

[0006] The connector includes a connecting body and a buckle hole located in the middle of the connecting body and engaging with the pull tab. The bottom end of the connecting body extends into an insertion part nested in the top of the pull tab. The insertion part has a positioning hole in its interlayer that is adapted to the engaging component.

[0007] Furthermore, in order to perform engagement and positioning, the engagement component includes an insertion groove located at the top of the pull tab and covering the insertion part, a positioning post vertically disposed in the insertion groove, and a locking block connected to the top of the positioning post in a fixed or detachable manner. The positioning post passes through the positioning hole, and the top of the positioning post extends into the buckle hole. The locking block is elastically engaged with the bottom end of the pull tab.

[0008] Furthermore, to prevent workers from cutting their hands or getting fabric threads caught during assembly, the top edge of the positioning post has a rounded corner.

[0009] Furthermore, in order to improve the stability of the engagement, the bottom end of the pull nose is provided with an engagement structure that is adapted to the card block. The engagement structure is one of a protrusion or a slot.

[0010] Furthermore, in order to allow the locking block to elastically disengage from the locking structure after the pull tab is pried open, the end of the locking block has an arc.

[0011] Furthermore, to improve the strength of the connection, the pull tab and the connector are connected by one of the following methods: adhesive bonding or hot pressing.

[0012] The beneficial effects of this utility model are: the pull tab and the connector are set separately, and the pull tab is provided with a through connector that elastically engages with the bottom of the pull nose. While ensuring the connection stability of the metal connector, the pull nose is positioned by using a snap-fit ​​connector made of elastic material to prevent shaking, effectively improving durability and preventing wear of the pull nose.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a zipper technical solution with a snap-fit ​​pull tab: its structure includes a zipper body 1, a pull nose 2, a connector 3, and a pull tab 4; the pull nose 2 is vertically disposed on the front end face of the zipper body 1; the connector 3 is movably fastened to the pull nose 2; the pull tab 4 is connected to the bottom of the connector 3, and the top of the pull tab 4 is provided with a snap-fit ​​element 41 that penetrates the connector 3 and elastically snaps into the bottom end of the pull nose 2;

[0022] The pull tab 4 is made of one of the following materials: plastic, glass, metal, or rubber, with plastic being the preferred material. After manufacturing, its edges are rounded to prevent scratching hands.

[0023] like Figure 2 As shown, the connector 3 includes a connecting body 31 and a buckle hole 32 located in the middle of the connecting body 31 and engaging with the pull tab 2. The length of the buckle hole 32 is greater than the length of the pull tab 2 connected to the rear contact end of the zipper body 1, so that the connector 3 can move back and forth relative to the pull tab. The bottom end of the connecting body 31 extends into an insertion part 34 nested in the top of the pull tab 4. The insertion part 34 has a positioning hole 33 that matches the engaging part 41 in its interlayer.

[0024] The positioning hole 33 is connected to the buckle hole 32.

[0025] like Figure 3 As shown, in order to perform locking and positioning, the locking component 41 includes an insertion groove 411 located at the top of the pull tab 4 and enclosing the insertion part 34, a positioning post 412 vertically disposed in the insertion groove 411, and a locking block 413 detachably connected to the top of the positioning post 412. The positioning post 412 passes through the positioning hole 33, and the top of the positioning post 412 extends into the buckle hole 32. The locking block 413 elastically engages with the bottom end of the pull tab 2.

[0026] The detachable method can be one of bolt fixing, snap-fit ​​fixing, or tight nested connection, with bolt fixing being preferred to improve the strength of the connection.

[0027] Among them, the card block 413 is made of one of the following materials: elastic plastic and rubber.

[0028] To prevent workers from cutting their hands or getting fabric threads caught during assembly, the top edge of the positioning post 412 has a rounded corner.

[0029] like Figure 5 As shown, in order to improve the stability of the engagement, the bottom end of the pull nose 2 is provided with an engagement structure 21 that is adapted to the locking block 413. The engagement structure 21 is a protrusion, and the end of the protrusion has an arc-shaped concave surface or an arc-shaped groove to facilitate the release of the locking block 413.

[0030] In order to allow the locking block 413 to elastically disengage from the locking structure 21 after the pull tab 4 is pried open, the end of the locking block 413 is curved.

[0031] To improve the strength of the connection, the pull tab 4 and the connector 3 are connected by one of adhesive bonding or hot pressing, preferably adhesive bonding, and the connector 3 is provided with a groove to strengthen the connection with the connector 3.

[0032] Principle: The pull tab 4 and the connector 3 are set separately. The pull tab 4 is provided with a locking part 41 that passes through the connector 3 and elastically engages with the bottom of the pull nose 2. While ensuring the connection stability of the metal connector 3, the locking part 41 with elastic material is selected to engage and position with the pull nose 2 to prevent shaking, effectively improve durability and prevent wear of the pull nose 2.
