Description

Technical Field

[0001] This utility model relates to the field of sewing supplies technology, and in particular to an eyelet button and a product with an eyelet button. Background Technology

[0002] An eyelet is a ring-shaped accessory used to reinforce holes in clothing, shoes, or bags. It typically consists of two parts: a buckle face and a base, which are secured by riveting or pressing. The core function of an eyelet is to prevent wear or tear on the edges of materials, while also serving a decorative purpose. They are commonly found in shoelace holes, clothing drawstring loops, and backpack buttonholes.

[0003] During the production of products with eyelet buckles, there is a possibility that the eyelet buckles may not be riveted tightly enough when installed. Products produced using traditional eyelet buckles in this situation have the following shortcomings: whether it is between the buckle and the base, or between the eyelet buckle and the base material (such as fabric), relative rotation may occur due to insufficient riveting, which will lead to the loss or reduction of some of the functions that the eyelet buckle should have, affecting the normal use of the product. Utility Model Content

[0004] In view of this, one objective of this utility model is to provide a corn eyelet fastener to eliminate or reduce the impact of insufficient riveting on the service life of products with corn eyelet fasteners. Another objective of this utility model is to provide products including the above-mentioned corn eyelet fastener.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A corn removal tool, comprising:

[0007] A fastener has a cylindrical body, and the outer circumferential surface of the cylindrical body is provided with a first concave-convex structure;

[0008] The base has an assembly hole fitted onto the outer circumferential surface of the cylinder. The wall of the assembly hole is provided with a second concave-convex structure, which corresponds to the position of the first concave-convex structure, so that the clamping gap formed by the base and the fastener has a convex anti-rotation section and / or a concave anti-rotation section.

[0009] Optionally, in the above-mentioned eyelet buckle, the first concave-convex structure includes a convex rib located on the outer peripheral surface of the cylinder, and the second concave-convex structure includes a notch corresponding to the position of the convex rib.

[0010] Optionally, in the above-mentioned eyelet buckle, the number of the protruding ribs is two or more, and they are evenly distributed around the axis of the cylinder.

[0011] Optionally, in the above-mentioned eyelet buckle, the orthographic projection of the protruding rib onto a plane that satisfies the perpendicular condition to the axis of the cylinder is rectangular.

[0012] Optionally, in the above-mentioned eyelet buckle, a guide structure is provided at one end of the protruding rib near the sleeve side of the cylinder, and the guide structure is used to guide the sleeve connection.

[0013] Optionally, in the above-mentioned eyelet buckle, the guide structure is set as a rounded chamfer or a sloping plane.

[0014] Optionally, in the above-mentioned eyelet buckle, the mounting hole has a pressing portion protruding along the axial direction of the mounting hole, and the buckle face is provided with a groove portion that cooperates with the pressing portion to clamp the base material.

[0015] Optionally, in the above-mentioned eyelet buckle, the buckle face is provided with a fixing part for fixing a portion of the rope-like part passing through the cavity of the cylinder.

[0016] Optionally, in the above-mentioned eyelet buckle, the buckle face has a buckle face body connected to the end of the cylinder, the buckle face body has an axial hole communicating with the cylinder cavity of the cylinder, and the buckle face body has a wire-locking groove connected to the axial hole on the side away from the cylinder, and the fixing part includes the wire-locking groove.

[0017] Optionally, in the above-mentioned eyelet buckle, the buckle face is set as a press-type cord buckle. The buckle face includes a first body with the cylinder and a second body movably assembled to the first body. Both the first body and the second body are provided with cord passages. The first body and the second body are connected by an elastic member. The second body can overcome the elastic restoring force of the elastic member and move relative to the first body when subjected to pressing pressure to loosen the cord of the fixing part.

[0018] A product with an eyelet clip includes a base material having a hole and an eyelet clip fixed to the hole, wherein the eyelet clip is an eyelet clip as disclosed in any of the above.

[0019] The eyelet clip provided by this utility model has the following beneficial effects:

[0020] This invention features a first concave-convex structure on the outer circumferential surface of the buckle body, and a second concave-convex structure on the wall of the mounting hole in the base. The second concave-convex structure corresponds to the first one. This creates a clamping gap with a convex and / or concave anti-rotation section when the base and buckle are fitted together, rather than a circular gap. This improves the anti-rotation capability of the eyelet buckle. Therefore, even if the riveting is not tight enough during the installation of the eyelet buckle in the production process, it is less likely to rotate or loosen, ensuring the product can be used normally. In summary, the eyelet buckle provided by this invention can eliminate or reduce the impact of insufficient riveting on the service life of products with eyelet buckles. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0054] In the description of this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] See Figures 1-26 This utility model provides a cornice buckle, which includes a buckle face 100 and a base 200. The buckle face 100 has a cylindrical body 110, and the outer peripheral surface of the body 110 is provided with a first concave-convex structure 111. The base 200 has an assembly hole 210 that fits onto the outer peripheral surface of the body 110. The hole wall of the assembly hole 210 is provided with a second concave-convex structure 211. The second concave-convex structure 211 corresponds to the first concave-convex structure 111, so that the clamping gap M formed by the base 200 and the buckle face 100 has a convex anti-rotation section and / or a concave anti-rotation section.

[0056] In traditional related technologies, the buckle 100 with a cylindrical body 110 is used in conjunction with the base 200 with a circular mounting hole 210. The base 200 and the buckle 100 are fitted together to form an annular gap. After the eyelet is installed into the hole of the base material 300 (such as fabric), the part of the base material 300 surrounding the hole is clamped in the annular gap by the base 200 and the buckle 100. However, since the part of the base material 300 that is clamped is circular along the circumference of the hole in the annular gap, it is easy to rotate and loosen during subsequent use, which will lead to the loss or reduction of some functions of the eyelet and affect the normal use of the product.

[0057] In view of this, the present invention provides a first concave-convex structure 111 on the outer circumferential surface of the cylindrical body 110 of the fastener 100, and a second concave-convex structure 211 on the wall of the mounting hole 210 of the base 200. The second concave-convex structure 211 corresponds to the first concave-convex structure 111. In this way, the gap formed by the fitting of the base 200 and the fastener 100 will no longer be a circular gap, but a clamping gap M with a convex anti-rotation section and / or a concave anti-rotation section. That is, the clamping gap M is not a circular path around the circumference of the hole in the base material 300. This can improve the anti-rotation capability of the eyelet buckle. Therefore, even if the riveting is not tight enough during the installation of the eyelet buckle in the production process of products with eyelet buckles, it is not easy for it to rotate and loosen, thus ensuring that the product can be used normally. It can be seen that the eyelet buckle provided by the present invention can eliminate or reduce the impact of insufficient riveting on the service life of products with eyelet buckles.

[0058] It should be understood that the clamping gap M is a local gap formed between the mounting hole 210 of the base 200 and the fastener 100 to accommodate the base material 300. It should be noted that the gap area corresponding to the convex rotating section of the clamping gap M is farther from the center of the mounting hole 210 than the gap areas adjacent to its two ends, and the gap area corresponding to the concave rotating section of the clamping gap M is closer to the center of the mounting hole 210 than the gap areas adjacent to its two ends. In other words, the type of rotating section is defined by its direction in the radial direction of the mounting hole 210. If it is oriented far away from the center of the mounting hole 210 in the radial direction, it is called a convex rotating section. Conversely, if it is oriented close to the center of the mounting hole 210 in the radial direction, it is called a concave rotating section.

[0059] The clamping gap M having a convex and / or concave resisting section includes three cases: the first case, the clamping gap M has only a convex resisting section; the second case, the clamping gap M has only a concave resisting section; and the third case, the clamping gap M has both a convex and a concave resisting section.

[0060] See Figure 5 , Figure 10 and Figure 12 In some embodiments, the first concave-convex structure 111 may include a rib located on the outer peripheral surface of the cylinder 110, and the second concave-convex structure 211 may include a notch corresponding to the position of the rib. In this structure, a convex blocking section for the clamping gap M is formed between the rib and the notch. The rib can be understood as a local protrusion on the outer peripheral surface of the cylinder 110, and the notch can be understood as a local depression on the inner wall of the assembly hole 210. It is easy to understand that a concave blocking section for the clamping gap M can be formed by interchanging the elements, that is, a local depression is provided on the outer peripheral surface of the cylinder 110 to form a groove along the axial direction of the cylinder 110, and a local protrusion is provided on the inner wall of the assembly hole 210 to form a protrusion corresponding to the position of the groove, and a concave blocking section for the clamping gap M is formed between the protrusion and the groove.

[0061] See Figure 5 and Figure 10 In some embodiments, the number of ribs can be two or more, and these ribs are evenly distributed around the axis of the cylinder 110. For example, four ribs can be provided, and they are distributed sequentially at 90° intervals along the circumference of the cylinder 110. See also Figure 5 In some embodiments, the orthographic projection of the rib onto a plane perpendicular to the axis of the cylinder 110 is rectangular, meaning the cross-section of the rib can be rectangular or approximately rectangular. Of course, in other embodiments, the cross-section of the rib can also be other shapes such as semicircular, trapezoidal, or dovetail-shaped, and this invention does not limit this to any particular shape.

[0062] See Figure 6 , Figure 10 and Figure 13 When using eyelet buckles, after the cylindrical body 110 of the buckle face 100 passes through the mounting hole 210 of the base 200, the end of the cylindrical body 110 on the fitting side (from which the base 200 is fitted onto the cylindrical body 110) undergoes a riveting process, i.e., the riveting end of the cylindrical body 110 is deformed outward. In some embodiments, a guide structure can be provided at the end of the protruding rib near the fitting side of the cylindrical body 110. The guide structure is used to guide the fitting, which can improve the efficiency of the fitting work. There are various choices for the form of the guide structure. For example, the guide structure can be set as a rounded chamfer or a sloping plane. Taking the sloping plane as an example, the top surface of the protruding rib near the fitting side of the cylindrical body 110 is inclined towards the axis of the cylindrical body 110, so that the protrusion height of this end of the protruding rib becomes smaller as it gets closer to the fitting side of the cylindrical body 110. In this way, when fitting, the guide structure formed by the sloping plane can make the fitting more successful.

[0063] See Figure 11 , Figure 13 and Figure 14In some embodiments, the mounting hole 210 may have a pressing portion 220 protruding axially along the mounting hole 210, and the fastener 100 may be provided with a groove portion that cooperates with the pressing portion 220 to clamp the base material 300. This arrangement improves the reliability of the connection between the base material 300 and the eyelet buckle, making the eyelet buckle less prone to rotation relative to the base material 300. When using the eyelet buckle, the base material 300 is located on one side of the base 200, and the portion of the base material 300 surrounding the hole folds over from the mounting hole 210 of the base 200 to the other side of the base 200, covering the pressing portion 220, such as... Figure 14 As shown, after the fastener 100 is riveted, the portion of the base material 300 that is turned onto the pressing part 220 is clamped by the pressing part 220 and the groove of the fastener 100.

[0064] In some embodiments, eyelet buckles can be designed with additional functions. For example, the buckle face 100 can be provided with a fixing part for partially securing a rope-like component passing through the cavity of the cylinder 110. By fixing the rope-like component locally with the fixing part, the eyelet buckle can achieve additional functions for the rope-like component. The structural form of the fixing part can be selected in various ways; see [reference needed]. Figure 1 , Figure 2 , Figure 4 and Figure 7 In some embodiments, the fastener 100 has a fastener body 120 connected to the end of the cylindrical body 110. The fastener body 120 has an axial hole 121 communicating with the cavity of the cylindrical body 110. A wire-locking groove 122 connected to the axial hole 121 can be formed on the side of the fastener body 120 away from the cylindrical body 110. The fixing part includes the wire-locking groove 122. It is easy to understand that the wire-locking groove 122 can partially fix rope-like components such as shoelaces and headphone cords. Taking an headphone cord as an example, after the headphone cord passes through the cavity of the cylindrical body 110 and the axial hole 121 of the fastener body 120, it can be partially locked into the wire-locking groove 122. This prevents the headphone cord from rotating relative to the eyelet buckle, thereby reducing the possibility of wear on the headphone cord at the eyelet buckle. Furthermore, the wire-locking groove 122 has a guiding function for rope-like components; that is, the extension direction of the wire-locking groove 122 is directional. Therefore, the rope-like component locked into the wire-locking groove 122 is guided in a specific direction.

[0065] See Figures 15-26In some embodiments, to achieve additional functions of the eyelet buckle, the buckle face 100 can be configured as a press-type cord buckle. The buckle face 100 may include a first body 101 with a cylindrical body 110 and a second body 102 movably mounted to the first body 101. Both the first body 101 and the second body 102 are provided with cord channels. The first body 101 and the second body 102 are connected by an elastic member 103. The second body 102 can move relative to the first body 101 under pressure to overcome the elastic restoring force of the elastic member 103, thereby loosening the cord at the fixing point. It should be noted that in this structure, the fixing point for partially fixing the cord includes two cord channels that can move relative to each other. One cord channel is located in the first body 101, and the other cord channel is located in the second body 102. The cross-sectional area of ​​the cord channels themselves allows the cord to pass through loosely. In use, the cord (e.g., a drawstring on clothing) passes through the cord channels of the first body 101 and the second body 102. It should be understood that the working principle of the press-type rope buckle is that, in its natural state, the rope passages of the first body 101 and the second body 102 are misaligned, so that the rope is clamped by the first body 101 and the second body 102 (at this time, the fixing part plays a fixing role). By pressing the second body 102, the rope passages of the first body 101 and the second body 102 can be aligned, so that the rope is loosened, thereby enabling the rope to be pulled and adjusted.

[0066] The second body 102 can have various modes of operation relative to the first body 101, for example, in Figures 15-17 In the exemplary embodiment, the second body 102 is pivotally connected to the first body 101. The second body 102 can rotate relative to the first body 101. When the second body 102 is pressed, it overcomes the elastic force of the elastic element 103 and moves relative to the first body 101 in a manner similar to closing a lid. After the second body 102 is released, it moves relative to the first body 101 in a manner similar to lifting a lid under the action of the elastic element 103. It should be noted that, since a limit stop structure is provided between the first body 101 and the second body 102, after the second body 102 is released, it moves relative to the first body 101 until the limit stop structure engages and stops. In other embodiments, the second body 102 can be slidably connected to the first body 101. For example, the second body 102 can slide relative to the first body 101 in a direction perpendicular to the axis of the cylinder 110, thereby achieving misalignment and alignment of the rope-threading channels.

[0067] In some embodiments, the elastic element 103 can be configured as a compression spring. Of course, in other embodiments, the elastic element 103 can be configured in other forms. For example, in an embodiment in which the second body 102 is pivotally connected to the first body 101, the elastic element 103 can be configured as a torsion spring.

[0068] Based on the eyelet buckle provided by this utility model, this utility model also provides a product with an eyelet buckle, which includes a base material 300 with holes, and the eyelet buckle is fixed to the holes in the base material 300. The product can be of various types, such as clothing, bags, shoes, etc., with eyelet buckles. Since the eyelet buckle disclosed in the above embodiments has the aforementioned technical effects, the product with the eyelet buckle also has the aforementioned technical effects, which will not be elaborated further here.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0070] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
