In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] The present application provides a tightening device, which is used to solve the problem that the tightening device is relatively fixed and unreliable, and the tightness adjustment is inconvenient in the related art.

[0051] Please refer to Figures 1 to 9 The tightening device comprises a take-up and pay-off mechanism 100, a seat body 200 and an end body 300. The take-up and pay-off mechanism 100 is used for the tightness adjustment of a wire rope 110. The take-up and pay-off mechanism 100 is arranged on the seat body 200; the seat body 200 is connected with a belt body 400, the wire rope 110 is arranged in the belt body 400, the take-up and pay-off mechanism 100 can adjust the tightness of the belt body 400 connected with the wire rope 110, and the seat body 200 is provided with a first connecting piece 210. The end body 300 comprises a second connecting piece, another belt body 400 is connected to the second connecting piece, and the second connecting piece is inserted or overlapped on the first connecting piece 210.

[0052] Specifically, in use of the tightening device, the seat body 200 and the belt 400 connected with the seat body 200 are arranged on the part of the article to be tightened, and the end body 300 and the other belt 400 connected with the end body 300 are arranged on the other part of the article to be tightened. When the tightness is adjusted, the end body 300 is inserted or overlapped on the seat body 200, so as to connect the two parts of the article to be tightened. Then, the tightness of the wire rope 110 is adjusted by the take-up and pay-off mechanism 100, and the tightness of the belt 400 is adjusted synchronously with the wire rope 110, so as to achieve the purpose of adjusting the tightness of the article to be tightened.

[0053] The tightening device has the seat body 200 and the end body 300, which are arranged on the parts of the article to be tightened respectively, so as to ensure the reliable connection between the tightening device and the article to be tightened, and prevent the seat body 200 and the end body 300 from being separated due to the large tightening force in use. The tightness can be adjusted freely by the take-up and pay-off mechanism 100, so as to make the tightening device convenient and fast to use, and easy to adjust and operate.

[0054] In one embodiment, as shown in Figures 1 to 5 In use, the second connecting member is inserted into the insertion part 220 of the first connecting member 210, so as to fix the first connecting member 210 and the second connecting member relative to each other, that is, to fix the seat body 200 and the end body 300 relative to each other. After the seat body 200 and the end body 300 are fixed relative to each other, the tightness can be adjusted by the take-up and pay-off mechanism 100.

[0055] In the embodiment, the first connecting member 210 and the second connecting member can be arranged in any structure according to actual conditions, as long as they can be inserted and connected detachably and fixed relative to each other after being inserted.

[0056] In one embodiment, as shown in Figures 1 to 5As shown, the second connecting member comprises an elastic part 310 and a limiting part 320, the limiting part 320 is arranged at one end of the elastic part 310, and the band 400 is connected to the other end of the elastic part 310 away from the limiting part 320; the limiting part 320 is inserted into the insertion part 220. In use, the limiting part 320 is directly inserted into the insertion part 220 to connect and relatively fix the first connecting member 210 and the second connecting member. Among them, the limiting part 320 is arranged on the elastic part 310, so that the limiting part 320 is more convenient during the insertion process, that is, even if the size of the opening of the insertion part 220 is smaller than that of the limiting part 320, the limiting part 320 can also be deformed under the support of the elastic part 310 and inserted into the insertion part 220, so as to ensure reliable connection and improve the practicability of the embodiment.

[0057] In one embodiment, as shown in the example, Figures 1 to 5 As shown, the insertion part 220 is a cavity formed with an opening, and a clamping hole communicating with the outside is further formed at a position away from the opening. The limiting part 320 passes through the opening, and after the elastic part 310 deforms, it is clamped in the clamping hole. During the insertion process, the limiting part 320 extends into the cavity. Because the space in the cavity is smaller than the space required by the limiting part 320, the limiting part 320 deforms under the support of the elastic part and is smoothly inserted into the cavity. After that, the limiting part 320 is clamped in the clamping hole, and the end body 300 is relatively fixed with the seat body 200.

[0058] When it is necessary to release the relative fixation of the end body 300 and the seat body 200, the operator directly presses or pushes the limiting part 320 in the clamping hole, so that the elastic part 310 deforms and the limiting part 320 is separated from the clamping hole and retracts into the cavity. At this time, the operator can separate the end body 300 from the cavity, so that the end body 300 and the seat body 200 are released from the relative fixation.

[0059] In one embodiment, as shown in the example, Figure 5 As shown, the end body 300 and the seat body 200 can also be connected to the same band 400. The end body 300 is connected to one end of the band 400, and the seat body 200 is connected to the other end of the band 400 away from the end body 300. In this way, after the relative fixation of the end body 300 and the seat body 200, the band 400 can form a closed shape under the cooperation of the embodiment, so as to be applied to suitable occasions and improve the applicability and application range of the embodiment.

[0060] In one embodiment, as shown in the example, the specific structure of the end body 300 and the seat body 200 is not limited when they are inserted and fixed. As long as the end body 300 and the seat body 200 can be relatively fixed, they can be. Figures 17 to 20As shown, the limiting portion 320 of the end body 300 has part of the structure protruding to the outside of the seat body 200 in the vertical direction, but the fixing member for fixed connection with the seat body 200 is arranged between the plurality of limiting portions 320 arranged on the end body 300, and the end body 300 and the seat body 200 can still be relatively fixed after being plugged.

[0061] It should be noted that when the end body 300 is plugged and connected with the seat body 200, the end body can be directly plugged into the seat body 200 along a straight line, or can be plugged into the seat body along an inclined direction, as long as it can be easily used in this embodiment.

[0062] As shown in the example, Figure 15 , Figure 16 As shown, the end body 300 is provided with a connecting hole 330, and the seat body 200 is correspondingly provided with a fixing member for connecting with the connecting hole 330. After the end body 300 is plugged into the seat body 200, the fixing member can cooperate with the connecting hole 330 to relatively fix the end body 300 and the seat body 200. In this embodiment, the end body 300 can be plugged into the seat body 200 in any direction, so that the end body 300 can be plugged into the seat body 200 when the embodiment is applied to a small straight space or a corner application scene, and the operation of the embodiment is simple and easy to use.

[0063] As an example, when the embodiment is applied to clothes, the belt body 400 is set to a suitable length and is arranged at the waist of a coat or a windbreaker, etc. to serve as a waistband when the user wears it, so that the clothes fit the wearer better.

[0072] It should be noted that in the embodiment, the rotating part 120 of the take-up and pay-out mechanism 100 includes a cover body for the operator to hold and operate the take-up and pay-out mechanism 100. The shape of the cover body is not limited in the embodiment, as long as it is convenient for the operator to hold. As shown in Figure 14 The cover body can be provided with any shape according to actual use scenarios or actual use needs, such as a circular shape, an elliptical shape, a triangular shape, a rectangular shape, a polygonal shape, or other irregular shapes.

[0073] In one embodiment, as shown in

[0074] The lapping part includes a groove, a first magnet is arranged in the groove, a protrusion is arranged on the second connecting piece, and a second magnet is arranged on the protrusion and attracts the first magnet. In this way, when the second connecting piece is lapped on the first connecting piece 210, the protrusion extends into the groove, and the first magnet and the second magnet are attracted to each other, so that the first connecting piece 210 and the second connecting piece are fixed relative to each other.

[0075] In one embodiment, as shown in Figure 21 Figure 22 ​​As shown, after the second connecting piece is overlapped on the overlapping portion, the first connecting piece 210 is fixed or rotates relative to the second connecting piece. The second connecting piece is provided with a connecting column 340, and a limiting groove 341 is formed in the connecting column 340 in a horizontal direction. A connecting groove is correspondingly provided on the first connecting piece 210, and a limiting ring is arranged in the connecting groove. When the second connecting piece is overlapped on the first connecting piece 210, the connecting column 340 extends into the connecting groove, and the limiting ring is clamped in the limiting groove 341. In this way, the first connecting piece 210 and the second connecting piece can be overlapped with each other, and the relative rotation of the first connecting piece 210 and the second connecting piece is not affected, so that the use scenarios of the embodiment are more diverse.

[0076] It can be understood that, in the embodiment, the first connecting piece 210 and the second connecting piece can also be connected in relative rotation by using other suitable structures.

[0077] In one embodiment, for example, the take-up and pay-out mechanism 100 includes a rotating portion 120 and a fixed portion 130. The rotating portion 120 is used to wind the wire rope 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 that communicates with the mounting cavity and faces the wire rope 110. The wire rope 110 passes through the opening and is connected to the rotating portion 120. When the embodiment is used, the fixed portion 130 is arranged on the seat body 200 and is fixed on the article to be tightened together with the seat body 200. The user only needs to operate the rotating portion 120, and the wire rope 110 can be taken up and paid out by the rotating portion 120, that is, the tightness of the wire rope 110 can be adjusted.

[0078] The rotating portion 120 can rotate relative to the fixed portion 130 and can be fixed relative to the fixed portion 130. The structure of the rotating portion 120 and the fixed portion 130 can be arbitrarily arranged according to actual conditions, as long as the use needs are met. For example, the rotating portion 120 includes a cover body. A first one-way tooth is arranged on the side of the cover body that faces the fixed portion 130. The fixed portion 130 is correspondingly provided with a first non-return portion. 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 in a first direction relative to the fixed portion 130 in one direction, so that the wire rope 110 can be taken up or loosened in one direction.

[0079] The first non-return portion also includes an elastic arm. The elastic arm is arranged on the side of the fixed portion 130 that faces the cover body and is arranged along the edge of the fixed portion 130. The elastic arm is arranged in a circular arc shape. The non-return tooth is arranged on the end of the elastic arm that is away from the fixed portion 130. In this way, when the cover body and the fixed portion 130 need to rotate in one direction, the non-return tooth engages with the first one-way tooth. When the cover body and the fixed portion 130 need to rotate in both directions, the elastic arm is pushed towards the center of the fixed portion 130, so that the non-return tooth disengages from the first one-way tooth, and the cover body can rotate relative to the fixed portion 130 in both directions.

[0080] In one embodiment, the cover is further provided with a second one-way tooth on the side facing the fixing part 130, the fixing part 130 comprises a second check part, the second one-way tooth is engaged with the second check part, so that the cover can only rotate with the fixing part 130 in a second direction, and the first direction is opposite to the second direction. The cover can move relative to the fixing part 130 in the vertical direction to control the cooperation or separation of the second one-way tooth and the second check part.

[0087] As shown in the example, Figures 1 to 4 As shown, the wire rope 110 is embedded in the braid 410, and the braid 410 is connected to the seat body 200. When the take-up and pay-off mechanism 100 adjusts the wire rope 110, the braid 410 will wrinkle or stretch again as the wire rope 110 tightens or loosens. In this way, when the take-up and pay-off mechanism 100 adjusts the wire rope 110, the wire rope 110 will not be self-wound due to long-term use, improving the practicability of the embodiment. The braid 410 can also protect the wire rope 110. In addition, adjusting the braid 410 by the take-up and pay-off mechanism 100 can also expand the application range of the embodiment and further improve the practicability of the embodiment.

[0088] In one embodiment, the belt body 400 includes a braid 410 and a braid cover 420. The braid cover 420 has a through hole communicating with the inside along its length direction. The braid 410 is connected with the wire rope 110 through the through hole. Under the action of the take-up and pay-off mechanism 100, the wire rope 110 moves to drive a part of the braid 410 to move in the braid cover 420. The braid cover 420 can protect the braid 410 from being directly exposed to the external environment and being affected by the external environment. In addition, the braid cover 420 can also avoid the braid 410 being exposed, making the embodiment as a whole more beautiful.

[0089] As shown in the example, Figure 11 As shown, when the embodiment is applied to a backpack, especially a single-shoulder bag, the wire rope 110 is arranged in the braid 410, and the braid 410 is arranged in the braid cover 420. When the take-up and pay-off mechanism 100 adjusts the tightness of the wire rope 110, the braid 410 will be adjusted in tightness, and the braid 410 always moves in the braid cover 420, making the adjustment process of the embodiment more safe and reliable. The appearance of the bag as a whole is more beautiful, and the adjustment process will not be disturbed by the external environment, improving the practicability of the embodiment.
