Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0035] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] The present application provides a fastening device for solving the problem in the related art that the fastening device is unreliable in fixation and cannot be flexibly applied to a variety of articles.

[0037] See also Figure 1 、 Figure 2 A fastening device includes a line-retracting mechanism 100 and a base 200. The line-retracting mechanism 100 is used to adjust the tightness of the line 110 so as to adjust the tightness of the article connected to the line 110. The base 200 includes a load-bearing portion 210 for carrying the line-retracting mechanism 100. A connecting portion 220 is provided at the edge of the base 200, extending away from the load-bearing portion 210, for connecting to the article to be fastened to fix the base 200; at least two connecting portions 220 are provided, and the plurality of connecting portions 220 are evenly distributed around the load-bearing portion 210.

[0038] Specifically, when using the tightening device of this embodiment, the seat body 200 is placed in a suitable position and fixed by the connecting portion 220; the multiple connecting portions 220 evenly distributed around the bearing portion 210 can ensure that the rope 110 is set in any direction of the seat body 200, and the bearing portion 210 can provide sufficient supporting force for the retractable line mechanism 100, so that the retractable line mechanism 100 can stably adjust the tightness of the rope 110.

[0039] After the seat 200 is fixed, the string 110 is loosened to the limit position and the string 110 is set at a position on any object that needs to be tightened. After the arrangement is completed, the string 110 and the object can be tightened by the retractable string mechanism 100.

[0040] In one embodiment, for example, Figures 1 to 6 As shown, the connecting portion 220 is a through slot or through hole. Thus, when the base 200 is fixed via the connecting portion 220, the base 200 can be fixed to the object to be fastened via the connecting portion 220 as long as the object to be fastened is provided with any belt-like or rope-like structure, thereby improving the applicability of this embodiment.

[0041] For example, Figure 1 、 Figure 2 As shown, the base 200 is provided with two connecting portions 220, and both connecting portions 220 are configured as elongated through slots. The elongated through slots can be configured as through slots of any shape, such as straight slots, arc slots, or rectangular slots, as long as the connecting portions 220 can secure the base 200 to the object to be fastened.

[0042] like Figure 11 As shown, for example, when this embodiment is applied to a bag, the bag has a wider belt 310 that is passed through the long strip-shaped through slot, and the mating surface between the belt 310 and the through slot is wider, which not only enables the base 200 to be reliably fixed to the bag, but also ensures the stability of the base 200 and prevents the base 200 from shaking, making this embodiment easy to use.

[0043] like Figure 8 、 Figure 9 As shown, for example, when this embodiment is applied to underwear, especially a bra, one of the through grooves is set as a straight groove for connecting with the strap 310 of the bra, and one of the through grooves is set as an arc groove for connecting with the cup of the bra or other irregular connection points, so that the seat body 200 can be better fixed on the bra.

[0044] When this embodiment is applied to a bra, Figure 9As shown, the seat 200 is arranged at the connection between the shoulder strap and the cup of the bra, and the cord 110 of the retractable wire mechanism 100 can be wound along the entire circumference or partial circumference of the cup. In this way, the size of the cup can be adjusted by adjusting the tightness of the cord 110 through the retractable wire mechanism 100.

[0045] When this embodiment is applied to a bra, Figure 9 As shown, the base 200 is positioned near the lower edge of the bra, between the two cups. The cord 110 of the retractable / retractable mechanism 100 is positioned at the lower edge of the cups. By adjusting the tension of the cord 110 by the retractable / retractable mechanism 100, the horizontal distance between the two cups can be adjusted, thereby achieving a gathering and shaping effect on the bra.

[0046] For example, Figure 3 、 Figure 4 As shown, the base 200 is provided with two connecting portions 220, one of which is configured as a through slot and the other as a through hole. The elongated through slot can be configured as any shape, such as a straight slot, a circular arc slot, or a rectangular slot, as long as the connecting portion 220 can secure the base 200 to the object to be fastened. The through hole can also be configured with different inner diameters as needed to facilitate the passage of the connecting rope when securing the base 200.

[0047] In one embodiment, for example, Figure 5 、 Figure 6 As shown, at least one connecting portion 220 is provided with a notch 221, so that the through-slot or through-hole communicates with the outside. Thus, when this embodiment is secured to an object to be fastened, the connecting rope or belt on the object to be fastened can be directly extended through the notch 221 into the through-slot, reducing the installation difficulty of this embodiment during use and making the securing process of the base body 200 simpler, more convenient, and easier to operate.

[0048] Please continue reading Figure 5 、 Figure 6 An anti-slip member is provided at the position of the notch 221 facing the interior of the through slot to prevent the connecting belt or connecting rope connected to the through slot from slipping out of the through slot. Exemplarily, the anti-slip member is provided as a hook, and the hook is provided in the direction of the through slot to prevent the connecting belt or connecting rope inserted into the through slot from slipping out at will.

[0049] In one embodiment, the wire retracting and releasing mechanism 100 includes a rotating portion 120 and a fixed portion 130. The rotating portion 120 is used to wind the wire 110. The fixed portion 130 is provided with a mounting cavity for mounting the rotating portion 120. The fixed portion 130 is also provided with an opening 131 facing the wire 110 and communicating with the mounting cavity. The wire 110 passes through the opening 131 and is connected to the rotating portion 120. When using this embodiment, the fixed portion 130 is disposed on the base 200 and is fixed to the object to be tied. The user only needs to operate the rotating portion 120 to retract and release the wire 110, that is, to adjust the tension of the wire 110.

[0050] The rotating portion 120 can rotate relative to the fixed portion 130 and can be fixed relative to the fixed portion 130. The structures of the rotating portion 120 and the fixed portion 130 can be arbitrarily set according to actual conditions, as long as they can meet the needs of use. For example, the rotating portion 120 includes a cover body, and a first one-way tooth is provided on the side of the cover body facing the fixed portion 130. A first non-return portion is correspondingly provided on the fixed portion 130, and the first non-return portion includes a non-return tooth that cooperates with the first one-way tooth. In this way, under the cooperation of the first one-way tooth and the non-return tooth, the cover body can rotate unidirectionally along the first direction relative to the fixed portion 130, thereby realizing unidirectional tightening or unidirectional loosening of the rope 110.

[0051] The first anti-return portion also includes an elastic arm, which is arranged on the side of the fixing portion 130 facing the cover body and is arranged along the edge of the fixing portion 130. The elastic arm is arranged in an arc shape, and the anti-return tooth is arranged on the end of the elastic arm away from the fixing portion 130. In this way, when the cover body and the fixing portion 130 need to rotate in one direction, the anti-return tooth engages with the first one-way tooth. When the cover body and the fixing portion 130 need to rotate in both directions, the elastic arm is moved toward the center of the fixing portion 130, so that the anti-return tooth disengages from the first one-way tooth, and the cover body and the fixing portion 130 can rotate in both directions.

[0052] In one embodiment, a second one-way tooth is further provided on a surface of the cover body facing the fixing portion 130. The fixing portion 130 includes a second non-return portion. The second one-way tooth engages with the second non-return portion, enabling the cover body to rotate only in a second direction relative to the fixing portion 130, with the first direction being opposite to the second direction. The cover body can move vertically relative to the fixing portion 130 to control the engagement or disengagement of the second one-way tooth with the second non-return portion.

[0053] When the cover body needs to be rotated in the first direction relative to the fixing portion 130, the cover body is controlled to disengage the second one-way tooth from the second non-return portion, and the cover body can be rotated unidirectionally in the first direction to a suitable position. After the string 110 is adjusted, the cover body is controlled to engage the second one-way tooth with the second non-return portion, and the cover body can be fixed relative to the fixing portion 130. Correspondingly, when the cover body needs to be rotated in the second direction relative to the fixing portion 130, the fixing portion 130 is controlled to move the elastic arm to disengage the non-return tooth from the first one-way tooth.

[0054] In one embodiment, for example, Figure 7 、 Figure 10 As shown, the number of openings 131 is set to an even number, and there are at least two. The two ends of the cord 110 extend into the installation cavity through two adjacent openings 131. Both ends of the cord 110 extend into the installation cavity. One end of the cord 110 is set on the fixed portion 130, and the other end of the cord 110 is wrapped around the rotating portion 120. In this way, the rotating portion 120 rotates to loosen or tighten the cord 110, making the tension adjustment process of the cord 110 more stable.

[0055] In this embodiment, the retractable wire mechanism 100 is provided with at least four openings 131, that is, it has two sets of wire ropes 110, so as to further improve the application scope of this embodiment and improve the practicality of this embodiment. When this embodiment is applied to a bra, the base 200 is set at the lower edge of the bra and is located between the two cups. The retractable wire mechanism 100 is set on the base 200, and the retractable wire mechanism 100 is provided with wire ropes 110 in the direction of the two cups, and the wire ropes 110 are wound around the edges of the cups. The retractable wire mechanism 100 can adjust the tightness of the wire ropes 110, and can adjust the distance and size of the two cups at the same time, so that the cups are more suitable for the user, thereby improving the practicality of this embodiment. Of course, if Figure 7 As shown, this embodiment can also be applied to other products that require a fastening device to simultaneously loosen or tighten two positions.

[0056] It should be noted that the line-retracting and releasing function in the line-retracting and releasing mechanism 100 can also use different structures, such as those described in CN118701491A, CN220364187U, CN220364182U, CN206413842U, CN218960176U, CN114735548A, CN106723663A, etc. Of course, the line-retracting and releasing function can also be other knob-type line-retracting and releasing structures in the relevant technology for retracting and releasing the rope 110.

[0057] See also Figures 8 to 11The present application further provides an article having a fastening device, comprising a cord 110, a belt 310, and the fastening device of any of the above-described embodiments. The cord 110 is connected to the belt 310. The fastening device is connected to the cord 110 and is used to adjust the tightness of the cord 110 and thereby the tightness of the belt 310.

[0058] The article with a fastening device provided in the embodiments of the present application has the fastening device of any one of the above embodiments. Therefore, the article with the fastening device has all the beneficial effects of the fastening device, that is, the article can be untied or tightened by the fastening device.

[0059] In one embodiment, the belt body 310 is an elastic webbing, and the cord 110 is connected to the elastic webbing. Under the action of the retractable wire mechanism 100, the cord 110 moves, thereby driving the elastic webbing. Controlling the elastic webbing via the cord 110 is simple and convenient. Using the elastic webbing as the belt body 310 further expands the scope of application of this embodiment. When applied to clothing or underwear, the relatively soft elastic webbing can better blend with the material of the clothing or underwear, ensuring the comfort of this embodiment during use.

[0060] In one embodiment, the belt body 310 illustratively includes a webbing sleeve and a webbing. The webbing sleeve has a through hole extending along its length, connecting the webbing to the interior. The webbing is inserted through the through hole and connected to the cord 110. Under the action of the retractable wire mechanism 100, the cord 110 moves, driving a portion of the webbing within the webbing sleeve. The webbing sleeve protects the webbing, preventing it from direct contact with the external environment and being affected by it. Furthermore, the webbing sleeve prevents the webbing from being exposed, enhancing the overall aesthetics of this embodiment.

[0061] For example, Figure 10 As shown, when this embodiment is applied to a bra, a webbing sleeve can be provided at the edge of the cup, and the cord 110 or at least a portion of the webbing is provided in the webbing sleeve, which can make the embodiment more beautiful as a whole and improve the overall comfort of the embodiment when in use.

[0062] In one embodiment, for example, the belt body 310 has a plurality of holes spaced apart along its length. The cord 110 is passed through the holes and connected to the belt body 310. Under the action of the retractable / retractable mechanism 100, the cord 110 moves, thereby driving the belt body 310 to move. By providing the plurality of holes, the movement path of the cord 110 during tightening or loosening can be controlled, so that the cord 110 can only move along a predetermined path, that is, it can only tighten or loosen the item to be tied along a predetermined direction.

[0063] For example, Figure 10As shown, when this embodiment is applied to a bra, the belt body 310 is arranged at the edge of the bra cup, and a plurality of wire holes are arranged at intervals in the belt body 310, thereby limiting the movement path of the cord 110, so that when the cord retracting and releasing mechanism 100 adjusts the cord 110, the bra cup can move in a preset direction to meet the user's adjustment needs.

[0064] In one embodiment, the articles include, for example, bras; bags such as backpacks, shoulder bags, handbags, sports bags, etc.; and clothing such as mountaineering clothing, sportswear, military uniforms, underwear, etc. Of course, the articles may also be other products that require a fastening device to be unfastened or tightened.

[0065] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0066] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
