[0034] 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 described clearly and completely below in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings herein can be arranged and designed in various different configurations.

[0035] One embodiment of an adjustable-length hanging strap includes a webbing 1, a connecting buckle A, and an adjusting buckle B. The first end 101 of the webbing 1 is fixedly connected to the connecting buckle insert A1. The second end 102 of the webbing passes sequentially through the adjusting buckle B and the connecting buckle A before being fixedly connected to the adjusting buckle insert B1. (The specific path of the second end 102 of the webbing 1 is as follows...) Figures 2-4 As shown, the second end 102 of the webbing 1 passes from the back of the adjusting buckle B to the front of the adjusting buckle B, then passes through two spacers B5 on the front and passes down to the back of the adjusting buckle B. Next, it passes through the first through groove A5 of the connecting buckle, passes around the connecting buckle stop A7 and the bevel A8, and then exits from the first through groove A5. Finally, it passes through the back of the adjusting buckle B and is fixedly connected to the back of the adjusting buckle insert B1. The length of the hanging strap can be adjusted by adjusting the position of the adjusting buckle B on the entire webbing. The adjusting buckle insert B1 is detachably connected to the adjusting buckle B, and the connecting buckle insert A1 is detachably connected to the connecting buckle A. The first end 101 of the webbing and the connecting buckle insert A1 are fixed by insert injection molding. The second end 102 of the webbing and the adjusting buckle insert B1 are fixed by sewing or snap-fitting. Alternatively, the second end 102 of the webbing and the adjusting buckle insert B1 can also be fixed by insert injection molding.

[0036] A second embodiment of the adjustable length hanging strap includes a webbing 1, a connecting buckle A, and an adjusting buckle B. The first end 101 of the webbing 1 is fixedly connected to the connecting buckle insert A1. The second end 102 of the webbing passes through the adjusting buckle B and the connecting buckle A in sequence and is fixedly connected to the adjusting buckle insert B1. The adjusting buckle insert B1 is detachably connected to the adjusting buckle B, and the connecting buckle insert A1 is detachably connected to the connecting buckle A. The second end 102 of the webbing and the adjusting buckle insert B1 are fixed by insert injection molding. The first end 101 of the webbing and the connecting buckle insert A1 are fixed by sewing or snap-fitting, or the first end 101 of the webbing and the connecting buckle insert A1 are also fixed by insert injection molding.

[0037] In the two embodiments described above, the insert injection molding is an existing injection molding process. That is, the first end 101 and the second end 102 of the webbing are placed into the injection mold as inserts, and the injection molding begins. After the injection molding is completed, the first end 101 and the second end 102 of the webbing are respectively injection molded and fixed to the connecting buckle insert A1 and the adjusting buckle insert B1 to form an integral unit. The specific process details of this insert injection molding are existing technologies and will not be described in detail here.

[0038] The webbing 1 in the two embodiments described above can be existing nylon webbing, terylene webbing, PP polypropylene webbing, etc., and the connecting buckle A, adjusting buckle B, connecting buckle insert A1 and adjusting buckle insert B1 can be made of plastic, rubber or silicone.

[0039] The manufacturing method of the adjustable length strap in the above embodiment is as follows: Webbing, connecting buckles, and adjusting buckles are pre-made separately. The first end of the webbing is placed as an insert in the connecting buckle mold of an injection molding machine. The injection molding machine starts working, and after it starts, the connecting buckle insert and the first end of the webbing are integrated in the connecting buckle mold. Then, the connecting buckle insert and the connecting buckle are detachably connected (this can be a snap-fit ​​connection, screw locking, or interference fit connection, etc.). The second end of the webbing passes through the adjusting buckle and the connecting buckle in sequence (or the first and second ends of the webbing are connected to the adjusting buckle and the connecting buckle before the insert is injection molded). The second end of the webbing is placed as an insert in the adjusting buckle mold of the injection molding machine. The injection molding machine starts working, and after it starts, the adjusting buckle insert and the second end of the webbing are integrated in the adjusting buckle mold. Then, the adjusting buckle insert and the adjusting buckle are detachably connected (this can be a snap-fit ​​connection, screw locking, or interference fit connection, etc.).

[0040] The method of using the adjustable length strap in the above embodiment: To extend the length of the strap (i.e., to make...) Figure 2 The distance from point L1 to point L2 increases, which means the length of the two layers of webbing in the first segment 103 is to be shortened. This is achieved by holding the adjusting buckle B still with the first hand, and pulling the second segment 104 located between the adjusting buckle and the connecting buckle with the second hand. Then, holding the connecting buckle A still with the first hand, the thumb and forefinger of the second hand hold the adjusting buckle, while the little finger and ring finger hold the second segment 104 still. Finally, the distance between the two hands is increased, thus completing the action of extending the length of the hanging strap. The desired length of the hanging strap (i.e., shortening the length of the hanging strap) is to be shortened. Figure 2 When the distance between L1 and L2 is shortened, which means the length of the two layers of webbing in the first segment 103 is lengthened, the adjusting buckle and connecting buckle are grasped by both hands respectively, and the distance between the two hands is widened, which will lengthen the length of the two layers of webbing in the first segment 103, thus shortening the length of the hanging strap.

[0041] The connecting buckle insert A1 and the connecting buckle A can be detachably connected by a snap-fit ​​(the snap-fit ​​connection can be that the connecting buckle A has a slot A2 for installing the connecting buckle insert, the side of the connecting buckle insert has a limiting protrusion A3, and the side wall of the slot has a limiting groove A4 corresponding to the limiting protrusion. The two are relatively fixed by the snap-fit ​​of the limiting protrusion A3 and the limiting groove A4), or the connecting buckle insert A1 and the connecting buckle A can be connected by a screw, which can be tightened when fixed, or the connecting buckle insert A1 and the connecting buckle A can be detachably connected by an interference fit, that is, the connecting buckle A has a slot, and the connecting buckle insert A1 and the slot are interference fit to achieve connection and fixation.

[0042] In order to avoid the object (such as ID card, etc.) hung by the lower end of the belt from being twisted and tilted when the object is light, the first end of the connecting buckle A is provided with a first through slot A5 and a second through slot A6 which are misaligned in the transverse direction (the vertical direction of the belt entering the connecting buckle, as shown in Figure 9 The position of the slot A2 opposite to the first through slot A5 is provided with a connecting buckle stopper A7 which is in the shape of a sheet and integrally connected to the connecting buckle on both sides. The side of the connecting buckle stopper away from the first through slot is a bevel A8. The belt enters the first through slot A5, passes around the connecting buckle stopper A7 and then exits from the first through slot A5. The belt 1 is guided and supported by the bevel A8 of the connecting buckle stopper, so that the belt exiting from the connecting buckle is tilted towards one side (left side as shown in Figure 9 The first end 101 of the belt passes through the second through slot A6 and is fixedly connected to the connecting buckle insert (the first end 101 of the belt needs to pass through the second through slot A6 and extend a certain length into the slot before insert injection molding), and the belt exiting from the second through slot is tilted towards the other side (right side as shown in Figure 9 So that the belts exiting from the first through slot and the second through slot are in V shape.

[0043] If the first through slot and the second through slot are not misaligned in the transverse direction, and from the front direction, the belts exiting from the first through slot and the second through slot are overlapped, then after the belt is hung on the user's neck, the belts near the first through slot and the second through slot will drive the connecting buckle A to twist, so that the light object such as ID card is always in a twisted state (i.e. the ID card cannot be close to the front chest of the wearer), and the present application misaligns the first through slot and the second through slot in the transverse direction, and guides and supports the belt 1 by the bevel A8 so that the belt exiting from the connecting buckle is tilted towards one side, and the belt exiting from the second through slot is tilted towards the other side, so that the belts exiting from the first through slot and the second through slot are in V shape.

[0044] In order to make the belt exiting from the second through slot tilted towards the other side (right side as shown in Figure 9 The connecting buckle insert A1 and the slot A2 for installing the connecting buckle insert are both in rhombus shape, the first end 101 of the belt is embedded in the connecting buckle insert in a symmetrical manner, and the two side edges of the first end of the belt are flush or close to the rhombus side edges of the connecting buckle insert, i.e. in the case that the two side edges of the first end of the belt are flush or close to the rhombus side edges of the connecting buckle insert, the belt exiting from the second through slot is tilted towards the other side, and if the connecting buckle insert A1 and the slot A2 for installing the connecting buckle insert are both in rectangular shape, the belt exiting from the second through slot will not be tilted (the belt exits from the connecting buckle A in a flat manner, as shown in Figure 15If the contact area between the connecting buckle and the belt is small, the connection is weak (as shown in FIG. 1C). Figure 16 If the contact area between the connecting buckle and the belt is small, the connection is weak (as shown in FIG. 1C).

[0045] Specifically, the first end face of the connecting buckle stopper is parallel to the second end face of the connecting buckle stopper, the bevel of the connecting buckle stopper forms an angle of 10-20 degrees with the first end face or the second end face, and the two opposite angles of the rhombus-shaped connecting buckle insert are 70-80 degrees. Preferably, the bevel of the connecting buckle stopper forms an angle of 15 degrees with the first end face or the second end face, and the two opposite angles of the rhombus-shaped connecting buckle insert are 75 degrees.

[0046] In order to design reasonably, the limiting convex parts are arranged on the diagonal sides of the two side edges of the rhombus-shaped connecting buckle insert.

[0047] In order to realize that the second end of the connecting buckle can be connected to different objects according to different use requirements, the second end of the connecting buckle is fixedly connected to the first end of the extended belt 2 by insert injection molding process, the second end of the extended belt 2 is connected to the hook or clip 3, and the hook or clip can hang the mobile phone case (in which the mobile phone is placed), the work card, etc.

[0048] Two strip-shaped holes A9 are arranged on the connecting buckle insert, which are process holes during injection molding.

[0049] The adjusting buckle insert B1 is detachably connected to the adjusting buckle B by buckling, or the adjusting buckle insert B1 is detachably connected to the adjusting buckle B by screwing, or the adjusting buckle insert B1 is detachably connected to the adjusting buckle B by interference fit.

[0050] Specifically, the adjusting buckle insert B1 is in the shape of a cuboid, the adjusting buckle has a rectangular notch B2 for mounting the adjusting buckle insert, the side edge of the adjusting buckle insert is provided with a limiting convex strip B3, and the side wall of the rectangular notch is provided with a limiting concave groove B4 corresponding to the limiting convex strip. After the adjusting buckle insert B1 is inserted into the rectangular notch B2, the relative fixation of the adjusting buckle insert B1 and the adjusting buckle B is realized by limiting the limiting convex strip B3 through the limiting concave groove B4.

[0051] The adjusting buckle is in the shape of a rectangle, two partition strips B5 are arranged in the rectangular frame, the first channel B6 and the second channel B7 for the belt to pass through are respectively formed between the two partition strips B5 and the rectangular frame, the rectangular notch B2 is formed between the two partition strips, the adjusting buckle insert is clamped in the rectangular notch, the second end 102 of the belt is vertically embedded and fixed on the back of the adjusting buckle insert, the belt passes through the first channel B6 from the back of the adjusting buckle, passes through the two partition strips B5, and then passes into the second channel B7 from the front of the adjusting buckle to the back of the adjusting buckle (as shown in FIG. 2C). Figure 3 If the contact area between the connecting buckle and the belt is small, the connection is weak (as shown in FIG. 1C).

[0052] The rectangular notch is a rectangular groove, which is arranged on the front surface of the adjusting buckle, the adjusting buckle insert piece is clamped into the rectangular notch from the front surface of the adjusting buckle, the limiting groove is arranged on the back surface close to the adjusting buckle, and the second end of the webbing is vertically embedded and fixed on the back surface of the adjusting buckle insert piece.

[0053] The component type adjusting buckle structure for the hanging belt makes the end of the webbing fixedly connected with the adjusting buckle without needing to protrude one section and be bent for sewing, thereby saving the cost of one section of the webbing and the process and time of sewing the end, and also making the hanging belt more simple and beautiful; in addition, it is also beneficial to more smoothly adjust the length of the hanging belt (the specific reason is that the one section of the webbing protruding is close to the other webbing close thereto, thereby increasing the friction force of pulling and adjusting, and affecting the smoothness of adjusting the length of the hanging belt).

[0054] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application.
