Description

Technical Field

[0001] The utility model relates to the technical field of decorative accessories, in particular to a decorative fixing fastener. Background Art

[0002] In order to enhance the beauty of items, modern people will add some decorations to the surface of the items to beautify them, such as installing decorations on the holes of hole shoes, wearing decorations on the straps of backpacks, etc. The addition of decorations helps to attract people to buy items.

[0003] When decorating an object's surface, it is usually done in conjunction with the use of fasteners. For example, when decorating the outside of a hole in a Crocs shoe, the fastener needs to pass through the hole in the Crocs shoe to connect with the surface of the Crocs shoe before the decorating can be installed. However, after the existing fastener passes through the hole in the Crocs shoe, the portion inside the hole does not fit the wall of the object inside the hole, and the distance between the two ends of the fastener is too large. This may cause the fastener to slide along the axis of the hole on the surface of the object when people walk in the Crocs, or the decorating connected to the fastener may shake outside the hole in the Crocs shoe, causing the decorating to easily fall off the fastener, affecting the aesthetics of the Crocs. Moreover, some fasteners connecting the decorating have the same cross-sectional area at both ends, while some on the surface When a cotton velvet ornament is connected to a fastener, the connection with the fastener can be achieved by inserting the sewing thread into the end of the fastener. However, the design of the two ends of the fastener with the same cross-sectional area will cause an obstruction to the insertion of the sewing needle when the needle and thread are inserted into one end of the fastener through the sewing equipment. As a result, when the ornament is connected to the fastener, the connection position between the fastener and the ornament cannot be placed under the sewing equipment as the lower layer for inserting the sewing thread. The connection position between the fastener and the ornament needs to be fixed as the upper layer with the help of auxiliary parts so that the sewing equipment can normally insert the sewing thread to achieve the connection between the fastener and the ornament. This method of connecting the fastener and the ornament is difficult and cannot take into account the needs of mass production of products connected with ornaments. Utility Model Content

[0024] Example 1:

[0025] This embodiment discloses a decorative fixing fastener, such as Figures 1 to 3 As shown in combination, the fastener consists of an inner buckle body 1, a connecting body 2 and an outer buckle body 3, the inner buckle body 1 and the outer buckle body 3 are respectively connected to the two ends of the connecting body 2, the end face of the inner buckle body 1 away from the connecting body 2 is a spherical surface, and both ends of the connecting body 2 are transitioned to the end of the inner buckle body 1 and the end of the outer buckle body 3 through a transition portion 4 with a conical axial section, the radial cross-section of the transition portion 4 is circular, and its radius increases as the distance to the inner buckle body 1 or the outer buckle body 3 decreases, the projection formed by the outer buckle body 3 on the plane perpendicular to the axis of the fastener covers the projection formed by the inner buckle body 1 on the plane perpendicular to the axis of the fastener, and the part of the outer buckle body 3 that does not cover the projection formed by the inner buckle body 1 is an extension portion 5.

[0026] It should be noted that the fastener of this embodiment is connected along the direction in which the inner buckle body 1 cooperates with the through hole on the surface of the article. The material of the through hole on the surface of the article is elastic. After passing through the through hole on the surface of the article, the inner buckle body 1 is located on the inner side of the surface of the article, and the connecting body 2 is fitted in the through hole on the surface of the article, while the outer buckle body 3 is located on the outer side of the surface of the article. During the use of the article, the transition part 4 will form a limiting structure with a gradually expanding radius at both ends of the connecting body 2, and abut against the surface of the article at both ends of the through hole. When the connecting body 2 slides along the axial direction of the through hole on the surface of the article, this action of the fastener is restricted, that is, the fastener is in the through hole on the surface of the article and at both ends of the axial direction of the through hole on the surface of the article. It fits with the wall surface of the article, so that the part of the fastener that fits with the through hole on the surface of the article is in contact with the surface of the article. The fit between the through holes is more compact, which reduces the shaking of the fastener during the use of the article and makes the position of the decoration connected by the fastener on the surface of the article more stable; in addition, the area of ​​the outer buckle body 3 on the plane perpendicular to the axis of the fastener is larger than that of the inner buckle body 1 on the plane perpendicular to the axis of the fastener, and the part of the outer buckle body 3 that is more than the inner buckle body 1 is the extension part 5. When the decoration is sewn to the fastener in the form of threading through the outer buckle body 3 with a sewing needle, the fastener can be placed above the decoration with the inner buckle body 1 on top and the outer buckle body 3 on the bottom, and then the sewing needle is directly used to thread the extension part 5. In this way, the connection between the fastener and the decoration is achieved. The position of the inner buckle body 1 will not affect the sewing of the sewing needle, and the connection method is simple, which is suitable for batch production and processing.

[0027] It needs to be further explained that, Figure 1 As shown, the edge of the end surface of the inner buckle body 1 away from the connecting body 2 is provided with a chamfer 10 that transitions to the side wall of the inner buckle body 1.

[0028] During the process of connecting the fastener to the surface of the object, the setting of the chamfer 10 can make it easier for the end of the inner buckle body 1 to dock with the through hole through the surface of the object, making it easier for the inner buckle body 1 to be pressed into the through hole, and the operation of connecting the fastener to the surface of the object is simpler.

[0029] Example 2:

[0030] This embodiment discloses a decorative fixing fastener, such as Figures 4 to 6As shown in combination, the fastener consists of an inner buckle body 1, a connecting body 2 and an outer buckle body 3, the inner buckle body 1 and the outer buckle body 3 are respectively connected to the two ends of the connecting body 2, the end face of the inner buckle body 1 away from the connecting body 2 is a spherical surface, and both ends of the connecting body 2 transition to the end of the inner buckle body 1 and the end of the outer buckle body 3 through a transition portion 4 with a conical axial section, the radial cross-section of the transition portion 4 is circular, and its radius increases as the distance to the inner buckle body 1 or the outer buckle body 3 decreases, the projection formed by the outer buckle body 3 on the plane perpendicular to the axis of the fastener covers the projection formed by the inner buckle body 1 on the plane perpendicular to the axis of the fastener, and the part of the outer buckle body 3 that does not cover the projection formed by the inner buckle body 1 is an extension portion 5, and a plurality of holes 6 are provided on the circumferential edge of the extension portion 5, and the projection formed by the hole 6 on the plane perpendicular to the axis of the inner buckle body 1 is located outside the projection formed by the inner buckle body 1 on the plane perpendicular to its axis.

[0031] It should be noted that: unlike Example 1, this embodiment adopts the method of threading the needle into the hole 6 and then connecting it to the surface of the decoration and tying the sewing thread to the extension 5 outside the hole 6 to achieve the connection between the fastener and the decoration. Moreover, the setting position of the hole 6 will not be affected by the position of the inner buckle body 1 during the process of needle and thread insertion, making the connection operation of the fastener and the decoration smoother.

[0032] It needs to be further explained that, Figure 5 and Figure 6 As shown in the figure, the hole 6 is a waist hole.

[0033] The waist hole design allows for more binding positions when a large amount of sewing thread needs to be inserted to ensure the tight connection between the fastener and the decoration. The sewing thread is tied to the extension 5 outside the hole 6 to meet the need for sewing thread connecting the fastener and the decoration in this case.

[0034] It needs to be further explained that, Figure 4 As shown, the edge of the end surface of the inner buckle body 1 away from the connecting body 2 is provided with a chamfer 10 that transitions to the side wall of the inner buckle body 1.

[0035] The setting of the chamfer 10 has the same function as that of the first embodiment, both of which are to make it easier for the inner buckle body 1 to be pressed into the through hole, and the operation of connecting the fastener to the surface of the object is simpler.

[0036] Example 3:

[0037] This embodiment discloses a decorative fixing fastener, such as Figures 7 to 10As shown in the figure, the fastener is composed of an inner buckle body 1, a connecting body 2 and an outer buckle body 3, the inner buckle body 1 and the outer buckle body 3 are respectively connected to the two ends of the connecting body 2, the end face of the inner buckle body 1 away from the connecting body 2 is a spherical surface, and both ends of the connecting body 2 are transitioned to the end of the inner buckle body 1 and the end of the outer buckle body 3 through a transition portion 4 with a conical axial section. The radial cross-section of the transition portion 4 is circular, and its radius increases as the distance to the inner buckle body 1 or the outer buckle body 3 decreases. The projection of the outer buckle body 3 on a plane perpendicular to the axis of the fastener is the same as the projection of the inner buckle body 1 on a plane perpendicular to the axis of the fastener. The projection formed on the outer buckle body 3 is covered, and the part of the outer buckle body 3 that does not cover the projection formed on the inner buckle body 1 is an extension portion 5. The end face of the extension portion 5 away from the inner buckle body 1 is provided with a cylindrical body 7, and the outer diameter of the cylindrical body 7 is the same as the outer diameter of the extension portion 5. The end of the cylindrical body 7 away from the extension portion 5 expands outward in the radial direction of the outer buckle body 3 to form an extension portion 8. The projection formed by the extension portion 8 on a plane perpendicular to the axis of the inner buckle body 1 surrounds the projection formed by the inner buckle body 1 on a plane perpendicular to its axis, and a plurality of holes 6 are provided along the circumferential edge of the extension portion 8.

[0038] Among them, the similarities between this embodiment and the second embodiment are that both realize the connection between the fastener and the decoration by threading the needle through the hole 6, connecting it to the surface of the decoration, and tying the sewing thread to the extension 5 outside the hole 6. The setting position of the hole 6 will not be affected by the position of the inner buckle body 1 during the process of threading the needle and thread, making the connection operation between the fastener and the decoration smoother.

[0039] The difference between this embodiment and the second embodiment is that: since the distance between the extension portion 8 and the central axis of the fastener is farther than the distance between the extension portion 5 and the central axis of the fastener, the connection position between the fastener and the decoration will be different from the connection position between the fastener and the decoration in the second embodiment, so that the fastener can be connected to a larger decoration; and due to the provision of the cylinder 7, the length of the fastener in the axial direction is increased, and the distance between the decoration and the surface of the object is also increased accordingly.

[0040] It needs to be further explained that, Figure 8 and Figure 10 As shown in the figure, a cavity 9 is formed in the cylindrical body 7.

[0041] Among them, the formation of the cavity 9 allows a flashing light to be placed in the cylinder 7, thereby further beautifying the surface of the object provided with fasteners and decorations. Sensors can also be placed in the cavity to realize intelligent control of the flashing light and expand the function of the structure formed by the fasteners and decorations.

[0042] It needs to be further explained that, Figures 8 to 10 As shown in the figure, the hole 6 is a waist hole.

[0043] The hole 6 in this embodiment adopts the waist hole design, which has the same function as that in the second embodiment. When a large amount of sewing thread needs to be inserted to ensure the tight connection between the fastener and the decoration, the sewing thread is tied to the extension part 5 outside the hole 6 to provide more binding positions to meet the need of sewing thread connecting the fastener and the decoration in this case.

[0044] It needs to be further explained that, Figure 7 As shown, the edge of the end surface of the inner buckle body 1 away from the connecting body 2 is provided with a chamfer 10 that transitions to the side wall of the inner buckle body 1.

[0045] Among them, the setting of the chamfer 10 in this embodiment has the same function as that of Example 1 and Example 2, both of which make it easier to press the inner buckle body 1 into the through hole, and the operation of connecting the fastener to the surface of the object is simpler.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
