DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0048] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The present application provides a tightening device for solving the problems in the related art that the tightening device is relatively unreliable in fixation and inconvenient in adjusting the tightness.

[0051] See also Figures 1 to 9 The tie-up device includes a wire-retracting and releasing mechanism 100, a seat body 200 and an end body 300. The wire-retracting and releasing mechanism 100 is used to adjust the tightness of the wire rope 110. The wire-retracting and releasing mechanism 100 is arranged on the seat body 200; the seat body 200 is connected to a belt body 400, and the wire rope 110 is arranged in the belt body 400. The wire-retracting and releasing 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 member 210. The end body 300 includes a second connecting member, and another belt body 400 is connected to the second connecting member. The second connecting member is plugged or overlapped on the first connecting member 210, so that the wire-retracting and releasing mechanism 100 and the seat body 200 are detachably connected.

[0052] Specifically, when the fastening device of this embodiment is used, the base 200 and the belt 400 connected to the base 200 are arranged at the part of the item to be fastened that needs to be fastened, and the end body 300 and another belt 400 connected to the end body 300 are arranged at another part of the item to be fastened that needs to be fastened. When adjusting the tension, the end body 300 is plugged or overlapped on the base 200 to connect the two parts of the item to be fastened, and then the tension of the cord 110 is adjusted by the retracting and releasing wire mechanism 100. The cord 110 is connected to the belt 400. When the cord 110 is adjusted, the cord 110 can drive the belt 400 to adjust the tension synchronously, thereby achieving the purpose of adjusting the tension of the item to be fastened.

[0053] The fastening device of this embodiment is generally divided into a base body 200 and an end body 300, which are respectively arranged at the parts of the items to be fastened, so as to ensure that the fastening device of this embodiment is reliably connected to the items to be fastened, and the base body 200 and the end body 300 will not be separated during use due to reasons such as large fastening force. The retracting and releasing mechanism 100 can freely adjust the tightness, making this embodiment convenient and quick to use, simple to adjust, and easy to use.

[0054] In one embodiment, for example, Figures 1 to 5 As shown, the first connector 210 includes a plug-in portion 220, and the second connector is plugged into the plug-in portion 220 and fixed relative to the first connector 210. When in use, the second connector is directly plugged into the plug-in portion 220 of the first connector 210, so that the first connector 210 and the second connector are relatively fixed, that is, the seat body 200 and the end body 300 are relatively fixed. The retractable wire mechanism 100 is arranged on the seat body 200, and after the seat body 200 and the end body 300 are relatively fixed, the retractable wire mechanism 100 can be used to perform tension adjustment operations.

[0055] In this embodiment, the first connector 210 and the second connector can be configured as any structure according to actual conditions, as long as they can be detachably plugged in and connected and can be relatively fixed after being plugged in.

[0056] In one embodiment, for example, Figures 1 to 5As shown, the second connector includes an elastic portion 310 and a limiting portion 320, wherein the limiting portion 320 is arranged at one end of the elastic portion 310, and the belt body 400 is connected to the other end of the elastic portion 310 away from the limiting portion 320; the limiting portion 320 is plugged into the plug-in portion 220. When in use, the limiting portion 320 is directly plugged into the plug-in portion 220 to connect the first connector 210 and the second connector and fix them relatively. Among them, the limiting portion 320 is arranged on the elastic portion 310, so that the limiting portion 320 is more convenient in the plug-in process. Even if the size of the opening of the plug-in portion 220 is smaller than the limiting portion 320, the limiting portion 320 can also be supported by the elastic portion 310, deformed and plugged into the plug-in portion 220, so as to ensure reliable connection and improve the practicality of this embodiment.

[0057] In one embodiment, for example, Figures 1 to 5 As shown, the plug-in portion 220 is a cavity formed with an opening, and a snap-in hole communicating with the outside world is formed at a position away from the opening on the cavity. The limiting portion 320 passes through the opening, and after being deformed with the elastic portion 310, it is snap-fitted into the snap-in hole. During the plug-in process, the limiting portion 320 extends into the cavity. Since the space in the cavity is smaller than the space required by the limiting portion 320, the limiting portion 320 is deformed with the support of the elastic member and smoothly plugged into the cavity. After that, the limiting portion 320 is snap-fitted into the snap-in hole, and the end body 300 and the seat body 200 are relatively fixed.

[0058] When the end body 300 and the seat body 200 need to be released from relative fixation, the operator directly presses or pushes the limiting portion 320 in the snap-in hole to deform the elastic portion 310 and disengage the limiting portion 320 from the snap-in hole and retract it into the cavity. At this time, the operator can remove the end body 300 from the cavity to release the relative fixation of the end body 300 and the seat body 200.

[0059] In one embodiment, for example, Figure 5 As shown, the end body 300 and the seat body 200 can also be connected to the same belt body 400, the end body 300 is connected to one end of the belt body 400, and the seat body 200 is connected to the end of the belt body 400 away from the end body 300. In this way, after the end body 300 and the seat body 200 are relatively fixed, the belt body 400 can form a closed shape with the cooperation of this embodiment, so as to be applied to suitable occasions, thereby improving the applicability and scope of application of this embodiment.

[0060] In one embodiment, for example, when the end body 300 is plugged and fixed with the base body 200, the specific structures of the end body 300 and the base body 200 are not limited, as long as the end body 300 and the base body 200 can be relatively fixed. Figures 17 to 20As shown, part of the limiting portion 320 of the end body 300 extends vertically to the outside of the seat body 200, but fixing parts for fixed connection with the seat body 200 are arranged between the multiple limiting portions 320 arranged on the end body 300, so that the end body 300 and the seat body 200 can still remain relatively fixed after insertion.

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

[0062] For example, Fig.15 , Fig.16 As shown, the end body 300 is provided with a connection hole 330, and the base body 200 is correspondingly provided with a fixing piece for connecting with the connection hole 330. After the end body 300 is plugged into the base body 200, the fixing piece can cooperate with the connection hole 330 to fix the end body 300 and the base body 200 relatively. In this embodiment, the end body 300 can be plugged into the base body 200 in any direction, so that when this embodiment is applied to application scenarios such as a small linear space or a corner, the end body 300 can also be plugged into the base body 200, making the operation of this embodiment simple and easy to use.

[0063] Exemplarily, when this embodiment is applied to clothes, the belt body 400 is set to a suitable length and is set at the waist of clothes such as coats or windbreakers. When the user wears it, it is used as a belt to make the clothes fit the wearer better.

[0064] In one embodiment, for example, Fig.10 As shown, when this embodiment is applied to a helmet, the base body 200 is connected to the edge of one side of the helmet through the belt body 400, and the end body 300 is connected to the edge of the other side of the helmet through another belt body 400. When in use, the end body 300 is plugged into the belt body 400, so that the two belt bodies 400 are connected to each other to form a safety rope for wearing the helmet. After the end body 300 is connected to the base body 200, the belt body 400 is adjusted to be tight through the wire retracting mechanism 100 so that the belt body 400 can fit the user's body.

[0065] In one embodiment, for example, Fig.11As shown, when this embodiment is applied to a backpack, especially a shoulder bag, a belt body 400 is provided on the backpack, and the two ends of the belt body 400 are respectively connected to the two ends of the backpack. At a connection portion between the backpack and the belt body 400, the end body 300 is provided on the backpack, and the seat body 200 is provided at the end of the belt body 400. When in use, the end body 300 is inserted into the seat body 200 so that the seat body 200 and the end body 300 are relatively fixed. After the connection between the end body 300 and the seat body 200 is completed, the length of the belt body 400 is adjusted by the retracting and releasing mechanism 100, so that the length of the belt body 400 of the backpack is more suitable for the user.

[0066] In one embodiment, for example, Fig.12 As shown, when this embodiment is applied to a backpack, especially a backpack, the base body 200 is connected to one of the shoulder straps of the backpack through the belt body 400, and the end body 300 is connected to the other shoulder strap of the backpack through the other belt body 400. When in use, the end body 300 is plugged into the belt body 400 to connect the two belt bodies 400. In this way, after the user puts on the backpack, the interconnected belt bodies 400 can be tied to the user's chest to serve as an auxiliary fixation of the backpack. The user can also adjust the length of the belt body 400 according to the retractable line mechanism 100 to adjust the belt body 400 to a suitable length, so that the auxiliary fixation effect of the belt body 400 is good.

[0067] In one embodiment, for example, Fig.23 As shown, when this embodiment is applied to a bag, a plurality of fastening devices are provided at the edge of the bag, and the plurality of fastening devices cooperate with the wearing portion to form a wearable bag, thereby facilitating the user to wear the bag on the body, and adjusting the bag to a suitable tightness through the fastening devices to improve comfort.

[0068] In one embodiment, for example, Fig.24 As shown, when this embodiment is applied to clothes, especially a jumpsuit or sea-hunting pants, this embodiment can be matched with the jumpsuit or sea-hunting pants to fix the bag on the user's chest and adjust it to a suitable tightness for the user to wear and use.

[0069] In one embodiment, for example, Figure 6 , Figure 7 As shown, a connection hole is further provided on the end body 300 at a position away from the base body 200. When in use, the end body 300 and the base body 200 are respectively connected to appropriate positions on the object to be fastened. When fastening is required, the end body 300 and the base body 200 are plugged and relatively fixed. The retractable wire mechanism 100 is provided with a wire rope 110, which is provided at a position on the object to be fastened that needs to be adjusted in tension. The retractable wire mechanism 100 can be used to adjust the tension of the position to be fastened.

[0070] In one embodiment, for example, Fig.13 As shown, when this embodiment is applied to clothes, the shoulder of the clothes is a split design, and the end body 300 and the base body 200 are respectively arranged on the two split parts of the split design. When in use, the end body 300 and the base body 200 are relatively fixed. The cord 110 is arranged at the position where the tightness needs to be adjusted on the shoulder, and the retractable wire mechanism 100 can adjust the tightness of the clothes by adjusting the tightness of the cord 110, so that the clothes are more fitted and decent when worn.

[0071] In one embodiment, for example, Figure 8 , Fig. 9 As shown, the end body 300 can also be provided with a plate shape according to actual needs, and a connecting shaft is provided at a position of the end body 300 away from the base body 200, so that the end body 300 can be fixed on other objects or appliances that require hinged connection, further expanding the scope of application of this embodiment.

[0072] It should be noted that, in this embodiment, the rotating part 120 of the retractable wire mechanism 100 includes a cover body, which is used for the operator to grasp and operate the retractable wire mechanism 100. This embodiment does not limit the shape of the cover body, as long as it is convenient for the operator to grasp. Fig.14 As shown, the cover body can be set to any shape according to the actual use scenario or actual use needs, such as circle, oval, triangle, rectangle, polygon or other irregular shapes.

[0073] In one embodiment, illustratively, the first connector 210 includes a housing, and a lap joint is provided on a side of the housing away from the retractable wire mechanism 100, and the second connector is lap jointed on the lap joint. The lap joint is provided on the first connector 210, and the second connector can be lap jointed on the lap joint and relatively fixed to the first connector 210. The structures of the first connector 210 and the second connector can be arbitrarily set according to actual conditions, as long as they can be overlapped and relatively fixed.

[0074] Exemplarily, the overlapping portion includes a groove, a first magnet is arranged in the groove, a protrusion is arranged on the second connecting member, and a second magnet that attracts the first magnet is arranged on the protrusion. In this way, when the second connecting member is overlapped on the first connecting member 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 member 210 and the second connecting member can be relatively fixed.

[0075] In one embodiment, for example, Fig.21 , Fig. 22As shown, after the second connecting member is overlapped on the overlapping portion, the first connecting member 210 and the second connecting member are relatively fixed or relatively rotated. The second connecting member is provided with a connecting column 340, and a limiting groove 341 is provided on the connecting column 340 in the horizontal direction. A connecting groove is correspondingly provided on the first connecting member 210, and a limiting ring is provided in the connecting groove. When the second connecting member is overlapped on the first connecting member 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 member 210 and the second connecting member can be overlapped with each other without affecting the relative rotation of the first connecting member 210 and the second connecting member, making the use scenarios of this embodiment more diverse.

[0076] It can be understood that, in this embodiment, the first connecting member 210 and the second connecting member can also adopt other suitable structures to achieve relative rotation connection.

[0077] In one embodiment, the wire retracting and releasing mechanism 100 includes a rotating part 120 and a fixing part 130, and the rotating part 120 is used to wind the wire rope 110. The fixing part 130 is provided with a mounting cavity for mounting the rotating part 120, and an opening communicating with the mounting cavity is also provided on the fixing part 130 in the direction of the wire rope 110, and the wire rope 110 passes through the opening and is connected to the rotating part 120. When using this embodiment, the fixing part 130 is provided on the seat body 200, and is fixed to the object to be fastened with the seat body 200. The user only needs to operate the rotating part 120 to realize the retraction and release of the wire rope 110 through the rotating part 120, that is, to realize the adjustment of the tightness of the wire rope 110.

[0078] Among them, the rotating part 120 can rotate relative to the fixed part 130, and can be fixed relative to the fixed part 130. The structures of the rotating part 120 and the fixed part 130 can be arbitrarily set according to actual conditions, as long as they can meet the use requirements. Exemplarily, the rotating part 120 includes a cover body, and a first one-way tooth is provided on the side of the cover body facing the fixed part 130, and a first check portion is correspondingly provided on the fixed part 130, and the first check portion includes a check tooth that cooperates with the first one-way tooth. In this way, under the cooperation of the first one-way tooth and the check tooth, the cover body can rotate unidirectionally along the first direction relative to the fixed part 130, thereby realizing unidirectional tightening or unidirectional loosening of the rope 110.

[0079] The first non-return portion further includes an elastic arm, which is arranged on a side of the fixing portion 130 facing the cover body and along the edge of the fixing portion 130. The elastic arm is arranged in an arc shape, and the non-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 non-return tooth is meshed 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 to disengage the non-return tooth from the first one-way tooth, and the cover body and the fixing portion 130 can rotate in both directions.

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

[0081] When the cover body needs to rotate in the first direction relative to the fixing part 130, the cover body is controlled to disengage the second one-way tooth from the second non-return part, and the cover body can rotate in the first direction to a suitable position. After the adjustment of the wire rope 110 is completed, the cover body is controlled to engage the second one-way tooth with the second non-return part, and the cover body can be fixed relative to the fixing part 130. Correspondingly, when the cover body needs to rotate in the second direction relative to the fixing part 130, the fixing part 130 is controlled to move the elastic arm to disengage the non-return tooth from the first one-way tooth.

[0082] It is understandable that the wire retracting and releasing mechanism 100 can use any structure as long as it can achieve the function of this embodiment and adjust the tightness of the wire rope 110 normally.

[0083] It should be noted that the retractable function of the retractable mechanism 100 can also use different structures, such as described in CN118701491A, CN220364187U, CN220364182U, CN206413842U, CN218960176U, CN114735548A, CN106723663A, etc. Of course, the retractable function can also be other knob-type retractable structures for retracting and releasing the rope 110 in the relevant technology.

[0084] See also Figures 10 to 13 The present application also provides an article with a fastening device, comprising a cord 110, a belt body 400, and the fastening device in any one of the above embodiments. The cord 110 is connected to the belt body 400. The fastening device is connected to the cord 110 and is used to adjust the tightness of the cord 110 to adjust the tightness of the belt body 400.

[0085] The article with a fastening device provided in the embodiments of the present application has the fastening device in any one of the above-mentioned 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.

[0086] In one embodiment, for example, Figures 10 to 12As shown, the belt body 400 is an elastic belt, and the cord 110 is connected to the elastic belt. Under the action of the retractable wire mechanism 100, the cord 110 moves to drive the elastic belt to move. It is simple and convenient to control the elastic belt through the cord 110. Setting the belt body 400 as an elastic belt can further expand the scope of application of this embodiment, so that when this embodiment is applied to clothes, helmets, and bags, the elastic belt with a relatively soft texture will not cause discomfort or damage to the human body when it comes into contact with the human body, thereby ensuring the comfort of this embodiment when in use and improving the user's experience.

[0087] For example, Figures 1 to 4 As shown, the cord 110 is embedded in the webbing 410, and the webbing 410 is connected to the seat 200. When the retractable mechanism 100 adjusts the cord 110, the webbing 410 will wrinkle or stretch again as the cord 110 is tightened or relaxed. In this way, when the retractable mechanism 100 adjusts the cord 110, the cord 110 will not be entangled due to long-term use, thereby improving the practicality of this embodiment. The webbing 410 can also protect the cord 110. In addition, the retractable mechanism 100 adjusts the webbing 410, which can also expand the scope of application of this embodiment and further improve the practicality of this embodiment.

[0088] In one embodiment, the belt body 400 includes a webbing 410 and a webbing sleeve 420. The webbing sleeve 420 has a through hole connected to the inside along its length. The webbing 410 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 to drive a part of the webbing 410 to move in the webbing sleeve 420. The webbing sleeve 420 can protect the webbing 410 and prevent the webbing 410 from directly contacting the external environment and being affected by the external environment. In addition, the webbing sleeve 420 can also prevent the webbing 410 from being exposed, making the overall appearance of this embodiment more beautiful.

[0089] For example, Fig.11 As shown, when the present embodiment is applied to a backpack, especially a shoulder bag, the cord 110 is set in the webbing 410, and the webbing 410 is set in the webbing sleeve 420. When the retracting and releasing mechanism 100 adjusts the tightness of the cord 110, it will drive the webbing 410 to adjust the tightness, and the webbing 410 always moves in the webbing sleeve 420, making the adjustment process of the present embodiment safer and more reliable. The overall appearance of the bag will be more beautiful, and the adjustment process will not be disturbed by the external environment, thereby improving the practicality of the present embodiment.

[0090] In one embodiment, for example, the belt body 400 is provided with a plurality of wire holes arranged at intervals along its length direction, and the wire rope 110 is passed through the plurality of wire holes and connected to the belt body 400. Under the action of the wire retracting and releasing mechanism 100, the wire rope 110 moves to drive the belt body 400 to move. By providing a plurality of wire holes, the moving path of the wire rope 110 when tightening or loosening can be controlled, so that the wire rope 110 can only move along a preset path, that is, the object to be fastened can only be tightened or loosened along a preset direction, thereby controlling the moving path of the belt body 400 when adjusting the tightness.

[0091] In one embodiment, illustratively, the articles include clothes, such as mountaineering clothes, sportswear, military uniforms, underwear, etc.; bags, such as backpacks, shoulder bags, single-shoulder bags, handbags, sports bags, etc.; helmets, etc.

[0092] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0093] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
