Abstract
Description
Technical Field
[0001] This application relates to the field of buckle technology, and in particular to a rope buckle and a product having a rope buckle. Background Technology
[0002] Fasteners are widely used today, and different types of fasteners have different fastening methods. They can be used on shoes, bags, or clothing simultaneously. Fasteners typically utilize a rope threaded through them, with the ends of the rope protruding. A fastener is inserted through the outer diameter of one end of the rope, allowing it to move along the outer diameter of the rope to adjust the opening size of the shoe, bag, or clothing. However, current fasteners using male and female fasteners have a large length and width in the projection plane perpendicular to the rope's direction because the female fastener needs to completely enclose the male fastener and uses a common spring to provide force to secure the rope. This makes it difficult to meet the demand for smaller fasteners. Therefore, reducing the length and width of the fastener in the plane perpendicular to the rope's direction has become a current research direction for fasteners. Utility Model Content

[0017] Preferably, the rope buckle as described above has a second protrusion protruding in the second direction on the sixth end face and / or the seventh end face, the second protrusion being located on the side of the second through hole near the tenth end face.
[0018] Preferably, in the rope buckle as described above, the edge of the tenth end face is provided with a transition curved surface.
[0019] Another embodiment of this application provides a product with a rope buckle, comprising: a rope and the rope buckle as described above, wherein the two ends of the rope pass through a first through hole and a corresponding second through hole, respectively, and are connected to the rope buckle.

[0039] See Figures 1 to 10 A preferred embodiment of this application provides a rope buckle, comprising:
[0040] Female buckle 1, male buckle 2 inserted into the female buckle 1, and conical spring 3 disposed in the female buckle 1;
[0041] The first end face 101 of the female buckle 1 is recessed inward along the first direction to form an accommodating space for the male buckle 2 to be inserted, and the accommodating space connects the second end face 102 and the third end face disposed opposite to each other on the female buckle 1, wherein the second end face 102 is adjacent to the first end face 101.
[0042] The fourth end face 103 of the female buckle 1 is provided with two first through holes 104 that extend from the accommodating space to the fifth end face of the female buckle 1 along the second direction. The fourth end face 103 is adjacent to the first end face 101 and the second end face 102. The fifth end face is opposite to the fourth end face 103. The second direction is perpendicular to the first direction and the fourth end face 103.
[0043] The male buckle 2 is provided with two second through holes 202 that penetrate the sixth end face 201 and the seventh end face that are opposite to each other on the male buckle 2, and the second through holes 202 correspond one-to-one with the first through holes 104. The eighth end face 203 on the male buckle 2 is coplanar with the second end face 102. The ninth end face on the male buckle 2 that is opposite to the eighth end face 203 is coplanar with the third end face. The eighth end face 203 is adjacent to the sixth end face 201.
[0044] One end of the conical spring 3 along the extension direction is connected to the bottom surface of the accommodating space away from the first end face 101, and the other end is connected to the tenth end face 204 of the male buckle 2 facing the bottom surface.
[0045] The rope buckle provided in this embodiment includes: a female buckle 1, a male buckle 2, and a conical spring 3 disposed in the female buckle 1. The female buckle 1 is recessed inward along a first direction on a first end face 101 for the male buckle 2 to be inserted, forming an accommodating space. When the male buckle 2 is inserted into the female buckle 1, at least a portion of the male buckle 2 is located within the accommodating space. Specifically, the accommodating space connects two opposite side end faces on the female buckle 1, namely the second end face 102 and the third end face. The corresponding side end face on the male buckle 2, namely the eighth end face 203, is coplanar with the second end face 102. The ninth end face, which is opposite to the eighth end face 203, is coplanar with the third end face. This makes the male buckle 2 and the female buckle 1 have the same width in a third direction perpendicular to the second end face 102 and the third end face. Compared with the case in the prior art where the male buckle 2 is completely wrapped by the female buckle 1, the width of the buckle in the third direction is reduced.
[0046] The fourth end face 103 of the female buckle 1 is provided with two first through holes 104 extending along the second direction through the accommodating space to the fifth end face of the female buckle 1. The male buckle 2 is provided with two second through holes 202 extending through the opposite sixth end face 201 and seventh end face, and the second through holes 202 correspond one-to-one with the first through holes 104, thereby facilitating the passage of the rope 4 through the female buckle 1 and the male buckle 2 (e.g., Figure 10 (As shown), to achieve the basic function of the fastener.
[0047] The conical spring 3, housed within the female buckle 1, has one end connected to the bottom surface of the accommodating space away from the first end face 101 along the extension direction (first direction), and the other end connected to the tenth end face 204 of the male buckle 2 facing the bottom surface. When the male buckle 2 is inserted into the female buckle 1 under external force, it compresses the conical spring 3, increasing the overlap area between the first through hole 104 and the second through hole 202, thus facilitating the passage of the rope 4. Subsequently, after the external force is removed, the male buckle 2 moves outward under the elastic force of the spring, reducing the overlap area between the first through hole 104 and the second through hole 202, thereby securing the rope 4. Simultaneously, by using the conical spring 3 instead of a conventional straight spring, the length of the compressed spring can be reduced after compression, which helps to decrease the length of the buckle in the first direction.
[0048] In summary, the rope buckle provided in this application embodiment connects the accommodating space in the female buckle 1 to the side end face, so that the side end faces of the male buckle 2 and the female buckle 1 can share the same end face. Furthermore, the tapered spring 3 reduces the length when the spring is compressed, thereby effectively reducing the length and width of the buckle on the plane perpendicular to the direction in which the rope 4 is threaded, effectively meeting people's demand for compact buckles.
[0049] It should be noted that, based on the premise that both the male buckle 2 and the female buckle 1 are hexahedrons, the first end face 101 of the female buckle 1 is preferably the upper end face, the second end face 102 and the third end face are the left and right end faces, and the fourth end face 103 and the fifth end face are the front and rear end faces. The first end face 101 is adjacent to the second end face 102, the third end face, the fourth end face 103, and the fifth end face, and both the second end face 102 and the third end face are adjacent to the fourth end face 103 and the fifth end face. Similarly, the sixth end face 201 and the seventh end face of the male buckle 2 are the left and right end faces, the eighth end face 203 and the ninth end face are the left and right end faces, and the tenth end face 204 is the lower end face. The tenth end face 204 is adjacent to the sixth end face 201, the seventh end face, the eighth end face 203, and the ninth end face, and both the sixth end face 201 and the seventh end face are adjacent to the eighth end face 203 and the ninth end face.
[0050] See Figure 5 Preferably, in the rope buckle as described above, on the projection plane perpendicular to the first direction, the width of the accommodating space along the third direction changes at least once according to a preset order, the third direction being perpendicular to the second end face 102 and the third end face, and the preset order being from small to large and then back to small;
[0051] On the projection surface, the width of the male buckle 2 along the third direction matches the accommodating space.
[0052] In this embodiment, on the projection plane perpendicular to the first direction, the width of the accommodating space along the third direction is not fixed, but varies according to a preset order, and the width of the male buckle 2 along the third direction matches the accommodating space, so that the male buckle 2 cannot be separated from the female buckle 1 in the third direction, thereby ensuring the stability of the connection between the male buckle 2 and the female buckle 1, especially the stability when the rope 4 is not inserted.
[0053] In a preferred embodiment, the preset sequence is from small to large and then back to small, so that the outlets at both ends along the third direction are small, ensuring that the male buckle 2 cannot pass through the outlet in the middle section of the third direction.
[0054] In another preferred embodiment, the width of the accommodating space along the third direction can also vary according to multiple preset sequences, further ensuring connection stability and improving the aesthetics of the fastener.
[0055] See Figure 5 Specifically, in the rope buckle described above, the fourth end face 103 is similar in shape to the first side of the accommodating space near the fourth end face 103;
[0056] The fifth end face has a similar shape to the second side of the accommodating space near the fifth end face.
[0057] In this embodiment, the shape of the fourth end face 103 is similar to, preferably the same as, the first side of the accommodating space, so that the thickness between the fourth end face 103 and the first side is the same. The shape of the fifth end face is similar to, preferably the same as, the second side of the accommodating space, so that the thickness between the fifth end face and the second side is the same, which helps to reduce the manufacturing cost of the fastener.
[0058] It should be noted that, in one embodiment, the first side and the second side have the same shape. In another embodiment, the first side and the second side have different shapes; optionally, either the first side or the second side is formed as a plane.
[0059] See Figure 5 Furthermore, as described above, the first end face 101 of the rope buckle on the projection plane is formed as a symmetrical shape.
[0060] In this embodiment, the first end face 101 is formed into a symmetrical shape on the projection plane, which helps to further improve the aesthetics and structural strength of the fastener.
[0061] See Figure 6 or Figure 8 Specifically, as described above, the rope buckle has a first protrusion 105 on its bottom surface and a first groove 205 corresponding to the first protrusion 105 on its tenth end face 204.
[0062] One end of the conical spring 3 is sleeved on the first protrusion 105 and connected to the female buckle 1, while the other end is inserted into the first groove 205 and connected to the male buckle 2.
[0063] In this embodiment, to ensure the stability of the connection of the conical spring 3, a first protrusion 105 is provided on the bottom surface of the accommodating space, and a first groove 205 corresponding to the first protrusion 105 is provided on the tenth end face 204 of the male buckle 2. One end of the conical spring 3 is sleeved on the first protrusion 105 and connected to the female buckle 1, and the other end is inserted into the first groove 205 and connected to the male buckle 2. The movement of the conical spring 3 is restricted by the first protrusion 105 and the first groove 205 on a plane perpendicular to the first direction, which helps to ensure the stability of the connection between the conical spring 3 and the buckle.
[0064] See Figure 2 , Figure 7 or Figure 9 Preferably, the rope buckle as described above has a second protrusion 206 protruding in the second direction on the sixth end face 201 and / or the seventh end face, and the second protrusion 206 is located on the side of the second through hole 202 near the tenth end face 204.
[0065] In this embodiment, a second protrusion 206 protruding in the second direction is provided on the sixth end face 201 and / or the seventh end face. The second protrusion 206 is located on the side of the second through hole 202 near the tenth end face 204, so that the second protrusion 206 can be inserted into the first through hole 104. By restricting the second protrusion 206 by the inner wall of the first through hole 104, the displacement of the male buckle 2 in the first direction can be limited, thereby ensuring the stability of the connection between the male buckle 2 and the female buckle 1.
[0066] See Figure 2 Preferably, in the rope buckle as described above, the edge of the tenth end face 204 is provided with a transition curved surface.
[0067] In this embodiment, the edge of the tenth end face 204 is provided with a transition surface to facilitate the insertion of the male buckle 2 into the female buckle 1.
