[0049] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] refer to Figure 1 and Figure 2 ,as well as Figures 10-12 A threading fastener for use with a threading device 300 is disclosed in this application. The threading fastener includes a first fastener 100, a second fastener 200, and a connecting portion 700 connecting the first fastener 100 and the second fastener 200. The threading fastener has an engaged state where the two fasteners are connected and a disengaged state where the two fasteners are separated. For ease of description, in the disengaged state, the first fastener 100 and the second fastener 200 each have a first axis and a second axis, respectively; in the engaged state, the first axis and the second axis are parallel or even coincident. In the following description of the embodiments, unless otherwise specified, the descriptions of "axial," "circumferential," and "radial" are based on the axial direction in the engaged state.

[0051] The first fastener 100 includes a first base 110 and a first wire clamping portion 120. The first base 110 has a wire hole 111 for the wire 300 to pass through. In one embodiment, the first base 110 extends in a radial plane of the first fastener 100, and the first wire clamping portion 120 extends along a first axial direction.

[0052] The second fastener 200 includes a second base 210 and a second wire clamping portion 220. In one embodiment, the first base 110 extends in the radial plane of the second fastener 200, and the second wire clamping portion 220 extends along a second axial direction. When the fastener is engaged, the first base 110 and the second base 210 are disposed opposite to each other, and the first wire clamping portion 120 and the second wire clamping portion 220 cooperate with each other to form a locking mechanism for clamping and fixing the threaded wire 300.

[0053] See Figure 3 and Figure 4In one embodiment, the connecting portion 700 is connected to the first base 110 and the second base 210, and the connection relationship can be integrally formed or a separate connection. The connecting portion 700 includes a bent portion 710 forming a take-up groove 714. In the engaged state, a gap 10 exists between the first base 110 and the second base 210, extending circumferentially. The boundary of the gap 10 is defined by the axial extension of the maximum radial edges of the first base 110 and the second base 210 (i.e.,...). Figure 4 Within the area of ​​the two dashed lines in the text.

[0054] The bent portion 710 extends into the gap 10, the take-up groove 714 has an outward-facing first opening 713, and the gap 10 also has an outward-facing second opening 11. The take-up groove 714 is connected to the gap 10 on both sides along the circumference. (Based on actual operation:)

[0055] See Figures 6-12 The thread 300 can pass through the threading hole 111 via the needle body 400. The first fastener 100 and the second fastener 200 engage with each other to clamp the thread 300, maintaining the relative fixation of the thread 300 and the thread fixing buckle. Excess thread exposed outside the thread fixing buckle (hereinafter referred to as thread end 340) is wrapped around and stored in the gap 10 and the take-up groove 714, resulting in a cleaner appearance. See again. Figure 4 In one embodiment, the connecting portion 700 includes a first end portion 701 and a second end portion 702 that respectively connect the first base portion 110 and the second base portion 210, and a bending portion 710 is disposed between the first end portion 701 and the second end portion 702. The connecting portion 700 is integrally formed with the first base portion 110 and the second base portion 210, and the bending portion 710 is pre-formed.

[0056] See also Figure 4 In one embodiment, the bending portion 710 includes a first segment 711 and a second segment 712 arranged opposite to each other to form a take-up groove 714. Both the first segment 711 and the second segment 712 have a root and a head. The roots of the two segments are located on opposite outer sides and are spaced apart to form a first opening 713. The root of the first segment 711 is connected to a first end 701, and the root of the second segment 712 is connected to a second end 702. The heads of the two segments are connected and located on opposite inner sides. When the threading fastener is in the engaged state, the head is located within the gap 10.

[0057] To facilitate winding operations, in one embodiment, the take-up groove 714 has a V-shaped structure, corresponding to an inwardly flared structure of the first opening 713. In one embodiment, the take-up groove 714 can engage with the threaded wire 300 near its bottom to prevent the threaded wire 300 from detaching. The connecting portion 700 has elastic deformation capability; when the threading fixing buckle switches from a disengaged state to a engaged state, the connecting portion 700 deforms, allowing the first base 110 and the second base 210 to rotate relative to the bent portion 710. Specifically, the deformation occurs at the connection position between the first end 701 and the first segment 711, and at the connection position between the second end 702 and the second segment 712.

[0058] Since the connection position is a repeatedly bent position, and the head is the main force application position of the wire end when winding, in one embodiment, the thickness of the first segment 711 and the second segment 712 gradually increases from the root to the head, which improves the deformation capability of the connection 700, while taking into account the structural strength of the bending part 710 at the head.

[0059] In some embodiments, the bent portion 710 is entirely or partially located inside the gap 10. Since the axial space of the gap 10 is limited, in a preferred embodiment, the roots of the first segment 711 and the second segment 712 are located outside the gap 10.

[0060] See Figure 5 In one embodiment, in the disengaged state, the first end 701, the second end 702, the first base 110, and the second base 210 are on the same plane. Specifically, in the disengaged state, the first base 110 and the second base 210 have a front side where the corresponding clamping portion is located and a back side opposite to it. The front sides of the first end 701, the second end 702, the first base 110, and the second base 210 overlap, which facilitates injection molding. That is, the first end 701 is a straight section in the plane where the first base 110 is located, and the second end 702 is a straight section in the plane where the second base 210 is located. In the engaged state, the connecting portion 700 is M-shaped.

[0061] In some embodiments, the thickness of the first end 701 is T1, the thickness of the first base 110 is T2, and T1:T2 = 0.3~0.6; the thickness of the second end 702 is T3, and the thickness of the second base 210 is T4, and T3:T4 = 0.3~0.6; in a preferred embodiment, T1 = T2. On the one hand, reducing the thickness of the first end 701 and the second end 702 can improve the deformation capability of the connection position; on the other hand, in the fastened state, the first end 701 and the second end 702 do not extend beyond the corresponding base in the axial direction.

[0062] See Figure 15In one embodiment, in the engaged state, the first end 701 abuts against the first segment 711, and the second end 702 abuts against the second segment 712. This further prevents the first end 701 and the second end 702 from extending axially beyond their respective bases in the engaged state.

[0063] See Figure 16 and Figure 17 In one embodiment, in the engaged state, the entire bent portion 710 is located inside the gap 10. Specifically, the first base 110 and the second base 210 have different radial dimensions; the radial dimension of the first base 110 is smaller than that of the second base 210. The root of the second segment 712 of the bent portion 710 is connected to the second base 210, and the root of the first segment 711 of the bent portion 710 is connected to the first base 110 by a first end portion 701. In the engaged state, the first end portion 710 is abutted against the first segment 711, and the second segment 712 is abutted against the second base 210.

[0064] See Figure 4 In one embodiment, in the engaged state, the head approaches the locking mechanism, causing the take-up groove 714 to extend as far into the space of the gap 10 as possible. Preferably, the head contacts the locking mechanism, and in the figure, the second wire clamping portion 220 wraps around the outer periphery of the first wire clamping portion 120, with the head and the outer periphery of the second wire clamping portion 220 in contact.

[0065] See Figures 1-4 In one embodiment, the first clamping portion 120 includes a first column 112 protruding from the first base 110, the internal space of the first column 112 being connected to the thread hole 111, and having a first central hole 113 aligned with the thread hole 111.

[0066] The second clamping portion 220 includes a second post 211 protruding from the second base 210. In the fastened state, the second post 211 and the first post 112 are inserted into each other, and there is a locking structure between them to restrict the separation of the first fastener and the second fastener. The second post 211 has a second central hole 213, and a third post 212 is disposed in the second central hole. In the fastened state, the third post 212 is inserted into the first central hole 113, and the first post 112 is inserted into the second central hole 213.

[0067] The third column 212 is inserted between the third column 212 and the first column 112, and has a first channel through which the thread 300 passes. The first channel is partially narrowed to form a first clamping part for clamping the thread 300. The first column 112 is inserted into the second column 211, and has a second channel through which the thread 300 passes between the first column 112 and the second fastener 200. The second channel is partially narrowed to form a second clamping part for clamping the thread 300.

[0068] In actual use, the threading fixing buckle clamps the thread 300 through the first and second thread-clamping parts, extending the length of the force exerted on the thread 300 and reducing the probability of the thread 300 moving relative to the threading fixing buckle. The interaction between the first, second, and third pillars and the thread increases the connection strength between the first fastener 100 and the second fastener 200, reducing the probability of the threading fixing buckle accidentally separating.

[0069] The threading hole 111 is a through hole with a cross-shaped cross section in the radial direction. The cross-shaped hole includes four side holes 1111. In one embodiment, the first fastener 100 has a slit 130 arranged radially to communicate with the threading hole 111. In the figure, the slit 130 is formed by the radial extension of one of the side holes 1111 of the threading hole 111. The slit 130 penetrates the first fastener 100 axially, facilitating the thread 300 to enter the threading hole 111 through the slit 130. Preferably, the slit 130 is an flared structure that gradually expands outward in the radial direction, further facilitating the thread 300 to enter the threading hole 111 radially through the slit 130. Of course, it can also pass through the threading hole 111 axially.

[0070] See Figures 6-15 This application also provides a quilt fastener, including a fastening base 500 with a thread 300 and a thread fastening buckle. The structure of the thread fastening buckle is as described in any embodiment of this application and will not be repeated here.

[0071] In actual use, one end of the thread 300 is equipped with a fixing seat 500, and the other end of the thread 300 is connected to the needle body 400. The thread passes through the object to be fixed 600 (such as a sheet and quilt) guided by the needle body 400. The part that passes through is defined as the first part. The fixing seat 500 is located on one side of the object to be fixed 600, and the first part and the needle body 400 are located on the other side of the object to be fixed 600.

[0072] The first part of the thread 300 enters the thread hole 111 from the cut 130 (e.g.) Figure 8 and Figure 9 ), or directly through the needle body 400 from the center of the thread hole 111 (e.g. Figure 6 and Figure 7 Then, insert one of the remaining three side holes 1111, which gradually narrows radially outward to clamp the first part of the thread 300. Then pull the first part radially outward to engage the second fastener 200 and the first fastener 100 to further clamp the first part.

[0073] Subsequently, the wire end 340 is wound around and placed within the gap 10, and is contained therein, reducing the exposed wire end. Preferably, there is a gap 330 between the first base 110 and the second base 210, and the free end of the wire end 340 can be inserted into the gap 330. At this point, the installation is complete. At this time, the wire fastening buckle and the fixing seat 500 are located on both sides of the object being fixed 600.

[0074] During disassembly, apply external force to both the first fastener 100 and the second fastener 200 simultaneously to separate them.

[0075] The threading fastener of this application has a first fastener and a second fastener connected by a connecting part, which reduces the probability of loss and facilitates the fastening operation after threading; and in the fastened state, the bent part of the connecting part protrudes into the gap, and the thread exposed outside the threading fastener is wrapped in the gap and the take-up groove, resulting in a simpler appearance.

[0076] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0077] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
