[0001] The utility model belongs to the technical field of buckle bodies, and particularly relates to a pull tab and a buckle body. Background Art

[0002] In the prior art, a buckle body is provided to facilitate the connection of the opening position of clothing and bags to control their open or closed state; the snap button, commonly known as a snap button, is one of the most widely used buckle bodies. Its specific structure includes a female buckle and a male buckle. The center of the female buckle has a card slot, and the center of the male buckle has a raised button bead. An elastic member such as a spring is often provided in the card slot, and the button bead is clamped by elastic force, so that the male buckle and the female buckle connect two different surface parts. It is widely used on clothing, bags, umbrellas and other items.

[0003] For most clothing, snap buttons are often located at the placket of the garment, and are opened and closed by pulling the garment. However, existing snap buttons are inconvenient to pull. Pulling and fastening the buttons can easily wrinkle the garment during long-term use, and can even damage the fabric and cause the buttons to come undone. Therefore, it is necessary to develop a pull tab and button body. Utility Model Content

[0004] The purpose of the present utility model is to provide a pull tab and a buckle body to solve the above-mentioned technical problems, wherein the pull tab body is provided with an extension portion, which is convenient for users to perform buckle operation due to a certain extension distance. After the user pulls the extension portion, force is applied to the slingshot cup to perform the buckle operation, which can effectively avoid applying force directly to the clothes, thereby avoiding the problem of wrinkling the clothes due to pulling, or even the problem of the clothes fabric being torn and falling off. At the same time, the assembly structure is a buckle body or a four-piece buckle body structure that further assembles the pull tab, and its buckling force does not change due to structural changes.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0006] A pull tab for a buckle body comprises a pull tab body which can be connected to a female buckle of the buckle body, and an extension portion which is fixedly connected to the pull tab body and extends to the outside of the pull tab body. Specifically, the outer cross-section of the pull tab body is circular, and the extension portion is fixedly connected to the pull tab body and extends beyond the axial projection range of the pull tab body; a pull tab is arranged between the first buckle surface and the slingshot cup assembly structure, wherein the pull tab has a pull tab body connected to the female buckle, so that the pull tab can be limited between the first buckle surface and the slingshot cup, and modularly assembled with the first buckle surface and the slingshot cup, which is convenient for operation and reduces production difficulty, wherein the pull tab body is provided with an extension portion, and since it has a certain extension distance, it is convenient for users to perform buckle operations. After pulling the extension portion, the user applies force to the slingshot cup to perform buckle operations, which can effectively avoid applying force directly to clothes, thereby avoiding pulling clothes and causing wrinkles in clothes, or even avoiding the problem of clothes fabric being torn and falling off. At the same time, this assembly structure is a buckle body or a four-in-one buckle body structure to further assemble the pull tab, and its buckling force does not change due to structural changes. The female buckle and the male buckle are fastened together to complete the relevant fastening operation, and the female buckle and the male buckle are separated to complete the relevant buckle pulling operation; wherein clothing fabric is arranged between the pull tab body and the slingshot cup.

[0007] Preferably, the pull tab body is provided with a first through hole. The first through hole is provided in the middle of the pull tab body. After the first connecting post passes through the first through hole, the end of the first connecting post is struck to form a curled edge, thereby contacting the inner surface of the slingshot cup, thereby fixing the pull tab body between the first buckle surface and the slingshot cup. The pull tab is further assembled through the buckle body or the four-piece buckle body structure. This assembly method is simple and easy to implement, and its buckling force does not change due to structural changes.

[0008] Preferably, a fitting groove and / or one or more abutment blocks penetrated by the first through hole are provided on one side of the pull tab body. Specifically, a fitting groove and / or one or more abutment blocks penetrated by the first through hole are provided on the side of the pull tab body facing the slingshot cup. The pull tab body is provided with a fitting groove that can be fitted with the slingshot cup, and the first through hole penetrates the fitting groove. The engaging groove, the first through hole and the pull tab body are all coaxially arranged. By setting the engaging groove and engaging the engaging groove with the pull tab body, the slingshot cup can be better fixed on the pull tab body, thereby improving the connection stability between the pull tab body and the slingshot cup. During the use of the pull tab, the pulling force when pulling the pull tab is transmitted to the pull tab body and the slingshot cup, thereby completing the buckle operation, improving the stability of the pulling force transmission process during the buckle operation, applying force to the slingshot cup, and performing the buckle operation, which can effectively avoid applying force directly to the clothes, thereby avoiding pulling the clothes and causing wrinkles in the clothes, or even avoiding the problem of the clothes fabric being torn and falling off.

[0009] Preferably, one or more abutment blocks are provided in the engaging groove to abut the bottom surface of the slingshot cup. Arranging one or more abutment blocks to abut the bottom surface of the slingshot cup provides an anti-slip effect. After the pull tab and the female buckle are assembled, the abutment blocks simultaneously abut the fabric, thereby preventing the rotation of the pull tab structure and causing wear on the fabric.

[0010] Preferably, a plurality of the interference blocks are arranged in a circular array with the first through hole as the center, and the interference blocks are arranged obliquely upward toward the axis of the first through hole. The obliquely arranged interference blocks have an inclined surface in the vertical direction. When the pull tab is subjected to rotational force, the inclined surface blocks the rotational force, and the resistance to rotation is greater, thereby improving the anti-slip effect and better preventing the pull tab from rotating as a whole. The interference blocks are arranged with the edge of the interlocking groove as the starting point toward the axis of the interlocking groove, and the width thereof is gradually reduced. The width of the interference block is gradually reduced, thereby improving the interference effect of the interference block on the bottom surface of the slingshot cup and improving the anti-slip effect.

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0028] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0029] Reference Figures 1 to 6 As shown, a pull tab for a buckle body comprises a pull tab body 1 connectable to a female buckle 3 of the buckle body, and an extension portion 2 fixedly connected to the pull tab body 1 and extending to the outside of the pull tab body 1 . Specifically, the outer cross-section of the pull tab body 1 is circular, and the extension part 2 is fixedly connected to the pull tab body 1 and extends beyond the axial projection range of the pull tab body 1; a pull tab is arranged between the first buckle surface 31 and the slingshot cup 32 assembly structure, wherein the pull tab has a pull tab body 1 connected to the female buckle 3, so that the pull tab can be limited between the first buckle surface 31 and the slingshot cup 32, and modularly assembled with the first buckle surface 31 and the slingshot cup 32, which is convenient for operation and reduces production difficulty, wherein the pull tab body 1 is provided with an extension part 2. Since it has a certain extension distance, it is convenient for users to perform buckle operations. After pulling the extension part 2, the user applies force to the slingshot cup 32 to perform the buckle operation, which can effectively avoid applying force directly to the clothes, thereby avoiding pulling the clothes and causing wrinkles to the clothes, or even the problem of the clothes fabric being torn and falling off. At the same time, this assembly structure is a buckle body or a four-in-one buckle body structure to further assemble the pull tab, and its buckling force does not change due to structural changes. The female buckle 3 and the male buckle 4 are fastened together to complete the related fastening operation, and the female buckle 3 and the male buckle 4 are separated to complete the related fastening operation; wherein clothing fabric is arranged between the pull tab body 1 and the slingshot cup 2.

[0030] The pull tab body 1 is provided with a first through hole 11. The first through hole is provided at a position that satisfies the pull tab body to be penetrated by the first connecting post 311 and connected to the slingshot cup. In this embodiment, the first through hole 11 is provided in the middle of the pull tab body 1. After the first connecting post 311 penetrates the first through hole 11, the end of the first connecting post 311 is struck to form a curled edge, thereby contacting the inner surface of the slingshot cup 32, so that the pull tab body 1 is fixedly provided between the first buckle surface 31 and the slingshot cup 32. The pull tab is further assembled through the buckle body or the four-piece buckle body structure. This assembly method is simple and easy to implement, and its buckling force does not change due to structural changes.

[0031] The pull tab body is provided with an interlocking groove and / or one or more abutment blocks penetrated by the first through hole on one side. Specifically, the pull tab body is provided with an interlocking groove and / or one or more abutment blocks penetrated by the first through hole on the side facing the slingshot cup. The pull tab body 1 is provided with an interlocking groove 12 that can interlock with the slingshot cup 32, and the first through hole 11 penetrates the interlocking groove 12. The engaging groove 12, the first through hole 11 and the pull tab body 11 are all coaxially arranged. By setting the engaging groove 12 and engaging the engaging groove 12 with the pull tab body 1, the slingshot cup 32 is better fixed on the pull tab body 1, thereby improving the connection stability between the pull tab body 1 and the slingshot cup 32. During the use of the pull tab, the pulling force when pulling the pull tab is transmitted to the pull tab body 1 and the slingshot cup 32, thereby completing the buckle operation, improving the stability of the pulling force transmission process during the buckle operation, applying force to the slingshot cup 32, and performing the buckle operation, which can effectively avoid applying force directly to the clothes, thereby avoiding pulling the clothes and causing wrinkles in the clothes, or even the problem of the clothes fabric being torn and falling off.

[0032] One or more abutment blocks 121 are provided in the engagement groove 12 to abut against the bottom surface of the slingshot cup 32. The abutment blocks 121 abut against the bottom surface of the slingshot cup 32 to prevent slipping. After the pull tab and the female buckle 3 are assembled, the abutment blocks 121 abut against the fabric, preventing wear of the fabric caused by the rotation of the pull tab.

[0033] The said resistance blocks 121 are arranged in a circular array with the first through hole 11 as the center, and the said resistance blocks 121 are arranged upwardly and tilted toward the axis of the first through hole 11. The tilted resistance blocks have a slope in the vertical direction. When the pull tab is subjected to rotational force, the resistance to rotation is greater due to the blocking effect of the slope on the rotational force, thereby improving the anti-slip effect and better preventing the pull tab from rotating as a whole. The said resistance blocks are arranged with the edge of the interlocking groove as the starting point toward the axis of the interlocking groove, and the width thereof is gradually reduced. The width of the resistance blocks is gradually reduced, thereby improving the resistance effect of the resistance blocks on the bottom surface of the slingshot cup and improving the anti-slip effect.

[0034] The extension portion 2 includes a first lever 21 and a second lever 22 fixedly connected to the pull tab body 1, and a third lever 23 fixedly connected to the first lever 21 and the second lever 22 at both ends. The first lever 21, the second lever 22, and the third lever 23 are all arranged in the same plane. The first, second, and third lever arms 21, 22, and 23 are connected to form a frame, with a third through-hole 20 provided in the middle of the frame for facilitating the pulling of the tab. During use, the user pulls the frame formed by the first, second, and third lever arms 21, 22, and 23, transmitting the corresponding pulling force to the slingshot cup 32, thereby completing the buckle pulling operation. Since the first, second, and third lever arms 21, 22, and 23 extend outward in the axial projection direction of the tab body 1, multiple areas are provided for the user to pull, thereby facilitating user operation. Furthermore, since the pulling force is transmitted through the frame, direct force applied to the clothing is effectively avoided, thereby preventing the clothing from being wrinkled or even torn and falling apart. The extension portion 2 is provided on the same plane as the tab body 1, giving the tab a sheet-like structure and a relatively thin overall structure.

[0035] A first curved surface 24 is provided between the first arm 21 and the third arm 23, and a second curved surface 25 is provided between the second arm 22 and the third arm 23. The first curved surface 24 and the second curved surface 25 are both provided on the inner surface of the frame. The chamfered radii of the first curved surface 24 and the second curved surface 25 are large, making it easier to break free when the frame is caught by branches or other objects.

[0036] One or more of the first, second, and third lever arms 21, 22, and 23 are provided with reinforcing ribs 26. Specifically, in the axial direction of the pull tab body 1, one or more of the first, second, and third lever arms 21, 22, and 23 are provided with reinforcing ribs 26 on one or both sides thereof. The reinforcing ribs 26 are provided on the frame to enhance the structural stability of the first, second, and third lever arms 21, 22, and 23, preventing the pull tab from breaking when subjected to strong pulling force.

[0037] A buckle body includes a female buckle 3 and a pull tab. The female buckle 3 includes a first buckle surface 31 and a slingshot cup 32 connected to the first buckle surface 31. A pull tab is arranged between the first buckle surface 31 and the slingshot cup 32. The two sides of the pull tab body 1 are respectively in contact with one side of the slingshot cup 32 and one side of the first buckle surface 31.

[0038] The pull tab body 1 is provided with a first through hole 11; the first buckle surface 31 is provided with a first connecting post 311 penetrating the first through hole 11 and connected to the slingshot cup 32;

[0039] The slingshot cup 32 is provided with a second through-hole 321 for the first connecting post 311 to pass through. The first through-hole 11, the second through-hole 321, and the first connecting post 311 are all coaxially arranged. The first connecting post 311 passes through the first through-hole 11 and the second through-hole 321. After striking the first connecting post 311, the end surface of the first connecting post 311 abuts against the end surface of the slingshot cup 32 where the second through-hole 321 is provided. This assembly method is simple and easy to implement, and its fastening force does not change due to structural changes. The first connecting post 311 abuts against the inner surface of the slingshot cup 32.

[0040] The buckle body also includes a male buckle 4; wherein the male buckle 4 includes a second buckle surface 41, a button bead 42, and a second connecting column 43. A fourth through hole 44 is provided in the middle of the button bead 42 for the second connecting column 43 to pass through and connect to the button bead 42.

[0041] An elastic washer 322 is provided inside the slingshot cup 32; the inner side of the elastic washer 322 is arranged toward the male buckle 4; the first connecting column 311 and the second connecting column 43 are both deformed by hitting to form curling edges on their end faces so as to limit and fix the slingshot cup 32 or the button bead 42 accordingly.

[0042] The pull tab and buckle body in this technical solution are used on clothing and bags; this technical solution retains the internal elastic components to ensure that the fastening force of the product does not change due to structural changes; the material on the engaging groove 12 is bent upward to form four anti-slip feet, i.e., resistance blocks, with anti-slip function. The four anti-slip points are set to prevent the pull tab from rotating after assembly; by pulling the extension part 2 of the pull tab, the four-button buckle is unfastened.

[0043] This technical solution provides a pull tab design for snap fasteners. In terms of assembly: compared to traditional Velcro, which requires sewing the hook and suede surfaces onto clothing, this product only requires one additional component when assembling the snap fastener, saving both the assembly process and the difficulty. Compared to existing technologies, this technical solution can accommodate more snap fasteners without the need for re-molding.

[0044] From the user experience point of view: by pulling the pull tab, the stress point is transferred from the connection between the clothing and the snap button to the connection between the pull tab and the snap button, which reduces the pulling on the fabric, thereby protecting the clothing and making the overall appearance more beautiful and durable;

[0045] At the same time, after the pull tab is assembled, the fabric is squeezed and not easily rotated due to the action of the non-slip feet, providing a more comfortable use experience; in addition, the silicone pull tab can better meet the current market demand for lightweight and reduce the friction and damage of metal pull tabs to clothing fabrics.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
