Description

TECHNICAL FIELD

[0001] The utility model relates to a connecting buckle used on a hanging belt, in particular to a hanging belt connecting buckle structure. BACKGROUND

[0002] The hanging belt is hung on the neck of a user to hang articles, such as a work card, a mobile phone, etc. Due to different heights of different users and different use requirements, the length of the hanging belt needs to be adjusted. To achieve the adjustment of the hanging belt, a connecting buckle and an adjusting buckle component are required.

[0003] The Chinese patents "hanging belt (three)" (publication number CN308589765S) and "hanging belt (V type)" (publication number CN308493082S) applied by the applicant cannot adjust the length of the hanging belt, and neither of the two patents has a connecting buckle and an adjusting buckle component.

[0004] The "weaving belt safety buckle" (publication number CN219047592U) applied by the applicant in 2023 includes a male buckle and a female buckle. The male buckle is composed of an upper cover plate and a lower buckle plate by ultrasonic welding. The inside of the male buckle is provided with a first pair of sharp spike insertion structure for fixing the weaving belt. One end of the male buckle is provided with a plug-in convex part. The female buckle is composed of an upper cover plate and a lower cover plate by ultrasonic welding. The inside of the female buckle is provided with a second pair of sharp spike insertion structure for fixing the weaving belt. One end of the female buckle has a plug-in concave cavity for the plug-in convex part to extend into. A matched elastic deformation clamping structure is arranged between the plug-in concave cavity and the plug-in convex part. The male buckle and the female buckle of the weaving belt safety buckle are connected by ultrasonic welding. Although the male buckle and the female buckle are provided, the male buckle and the female buckle cannot adjust the length of the hanging belt, and the production and manufacturing of the hanging belt cannot be facilitated.

[0005] In addition, the Chinese patent "a hanging belt" (publication number CN219146936U) is searched. It includes a connecting hard sheet with an opening at the top end. The central part of the connecting hard sheet is provided with a detachable buckle piece. The buckle piece is used to buckle two hanging belts. The end of one hanging belt is provided with a first buckle hole. The first buckle hole is detachably buckled with an extension belt. The extension belt is provided with a second buckle hole. The extension belt is also detachably buckled with other extension belts. The end of the other hanging point is provided with an adjusting needle buckle. The adjusting needle buckle is provided with a limiting needle. Although the patent can adjust the length of the hanging belt through two specifications, the hanging belt can be used not only on children but also on adults, but the adjustment is complicated and inconvenient.

[0006] In addition, the applicant has designed a connecting buckle and an adjusting buckle in the research and development process, the connecting buckle and the adjusting buckle are both in the shape of a rectangular frame body, a plurality of parallel partition strips are arranged on the connecting buckle and the adjusting buckle, and the two ends of a webbing are fixedly connected with the partition strips on the connecting buckle and the adjusting buckle, specifically, the ends of the webbing are bent by 180 degrees after penetrating through the partition strips and are sewn at the ends, so that there are multiple layers of the webbing at the positions where the webbing contacts the connecting buckle and the adjusting buckle, and the cost of the webbing is higher in the case of large quantities, and the process and time of sewing the ends are also increased. SUMMARY

[0031] The central control reset foot pedal and its combined connection method of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] 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.

[0034] The second embodiment of the adjustable length hanging belt comprises a woven belt 1, a connecting buckle A and an adjusting buckle B, a first end 101 of the woven belt 1 is fixedly connected to a connecting buckle insert sheet A1, a second end 102 of the woven belt is sequentially threaded through the adjusting buckle B and the connecting buckle A and then fixedly connected to an adjusting buckle insert sheet B1, the adjusting buckle insert sheet B1 is detachably connected to the adjusting buckle B, and the connecting buckle insert sheet A1 is detachably connected to the connecting buckle A; the second end 102 of the woven belt and the adjusting buckle insert sheet B1 are fixed by insert injection molding, the first end 101 of the woven belt and the connecting buckle insert sheet A1 are fixed by sewing or clamping, or the first end 101 of the woven belt and the connecting buckle insert sheet A1 are also fixed by insert injection molding.

[0035] In the above two embodiments, the insert injection molding is the existing injection molding process, that is, the first end 101 of the woven belt and the second end 102 of the woven belt are respectively placed as inserts into the injection mold, the injection molding starts to work, and after the injection molding is completed, the first end 101 of the woven belt and the second end 102 of the woven belt are respectively injection molded and fixed with the connecting buckle insert sheet A1 and the adjusting buckle insert sheet B1 to form an integrated body. The specific process details of the insert injection molding are prior art and will not be repeated here.

[0036] The woven belt 1 in the above two embodiments can be an existing nylon woven belt, a Teflon woven belt, a PP polypropylene woven belt, etc., and the connecting buckle A, the adjusting buckle B, the connecting buckle insert sheet A1 and the adjusting buckle insert sheet B1 can be made of plastic, plastic or silicone.

[0037] The method for manufacturing the adjustable length hanging belt in the above embodiments is as follows: the woven belt, the connecting buckle and the adjusting buckle are respectively manufactured in advance, the first end of the woven belt is placed as an insert in the connecting buckle insert sheet mold of the injection molding machine, the injection molding machine starts to work, and after the injection molding machine works, the connecting buckle insert sheet is integrated with the first end of the woven belt in the connecting buckle insert sheet mold, then the connecting buckle insert sheet is detachably connected with the connecting buckle (which can be buckling connection, screw locking or interference fit connection, etc.); the second end of the woven belt is sequentially threaded through the adjusting buckle and the connecting buckle (or the first end and the second end of the woven belt are first threaded through the adjusting buckle and the connecting buckle before insert injection molding), the second end of the woven belt is placed as an insert in the adjusting buckle insert sheet mold of the injection molding machine, the injection molding machine starts to work, and after the injection molding machine works, the adjusting buckle insert sheet is integrated with the second end of the woven belt in the adjusting buckle insert sheet mold, then the adjusting buckle insert sheet is detachably connected with the adjusting buckle (which can be buckling connection, screw locking or interference fit connection, etc.).

[0038] The method for using the adjustable length hanging belt in the above embodiments is as follows: the length of the hanging belt is to be extended (i.e. the length of the hanging belt is to be shortened), the first end 101 of the woven belt is pulled out of the connecting buckle A, and the second end 102 of the woven belt is pulled out of the adjusting buckle B. Figure 2When the distance between L1 and L2 is lengthened, i.e. the length of the two layers of the first section of the belt 103 is shortened, the first hand holds the adjusting buckle B still, the second hand pulls the second section of the belt 104 between the adjusting buckle and the connecting buckle, then the first hand holds the connecting buckle A still, the second hand holds the adjusting buckle with the thumb and the index finger and holds the second section of the belt 104 with the ring finger and the little finger, and then the distance between the two hands is increased, thus the length of the belt is lengthened. Figure 2 When the distance between L1 and L2 is shortened, i.e. the length of the two layers of the first section of the belt 103 is lengthened, the two hands hold the adjusting buckle and the connecting buckle respectively, and the distance between the two hands is increased, thus the length of the belt is shortened.

[0039] The connecting buckle insert A1 and the connecting buckle A can be detachably connected by buckling (the buckling 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 is provided with a limiting protrusion A3, the side wall of the slot is provided with a limiting slot A4 corresponding to the limiting protrusion, and the relative fixation of the two is achieved by buckling the limiting protrusion A3 and the limiting slot A4), or the connecting buckle insert A1 and the connecting buckle A are connected by a screw, the screw is locked when fixation is needed, or the connecting buckle insert A1 and the connecting buckle A are detachably connected by interference fit, i.e. the connecting buckle A has a slot, and the connecting buckle insert A1 and the slot are interference fit to achieve connection and fixation.

[0040] In order to avoid the object (such as a work card) hung at the lower end of the belt from being twisted and inclined 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 through the slot A2 and are staggered in the transverse direction (the vertical direction of the belt entering the connecting buckle, as shown in Figure 9 The position opposite the first through slot A5 in the slot A2 is provided with a connecting buckle stop sheet A7 which is in the shape of a sheet and is integrated with the connecting buckle on both sides. The side of the connecting buckle stop sheet away from the first through slot is a bevel A8. The belt enters the first through slot A5, passes around the connecting buckle stop sheet A7, and then exits the first through slot A5. The belt 1 is guided and supported by the bevel A8 of the connecting buckle stop sheet, so that the belt exiting the connecting buckle is inclined to 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 with the connecting buckle insert (the first end 101 of the belt needs to pass through the second through slot A6 into the slot and extend a certain length before insert injection molding), and the belt exiting the second through slot is inclined to the other side (right side as shown in Figure 9 Thus, the belt exiting the first through slot and the second through slot is V-shaped.

[0041] If the first and second through slots are not misaligned in the lateral direction, the webbing passing through the first and second through slots will overlap when viewed from the front. When the strap is hung around the user's neck, the webbing near the first and second through slots will be stressed and cause the connecting buckle A to twist, thus keeping lighter items such as name tags in a twisted state (i.e., the name tag cannot be close to the wearer's chest). This application uses the lateral misalignment of the first and second through slots and the guiding support of the inclined side A8 on the webbing 1 to make the webbing passing through the connecting buckle tilt to one side and the webbing passing through the second through slot tilt to the other side, so that the webbing passing through the first and second through slots is V-shaped.

[0042] To make the webbing that passes through the second through groove tilt to the other side ( Figure 9 (As shown on the right), both the connecting buckle insert A1 and the slot A2 for installing the connecting buckle insert are rhomboid. The first end 101 of the webbing is symmetrically embedded in the connecting buckle insert, and the two sides of the first end of the webbing are flush with or close to the rhomboid sides of the connecting buckle insert. That is, when the two sides of the first end of the webbing are flush with or close to the rhomboid sides of the connecting buckle insert, the webbing passing through the second through slot will tilt to the other side. However, if both the connecting buckle insert A1 and the slot A2 for installing the connecting buckle insert are rectangular, the webbing passing through the second through slot will not tilt (the webbing passes through the connecting buckle A1 in a straight line, such as...). Figure 15 As shown), this will cause the connecting buckle A to twist; or the contact area between the webbing and the connecting buckle insert is small, resulting in a weak connection (such as...). Figure 16 As shown, the rectangular connecting buckle insert has a small contact area with the webbing.

[0043] Specifically, the first end face of the connecting buckle is parallel to the second end face of the connecting buckle, the hypotenuse of the connecting buckle forms an angle of 10-20 degrees with the first end face or the second end face, and the two pairs of angles of the rhomboid connecting buckle insert are 70-80 degrees. Preferably, the hypotenuse of the connecting buckle forms an angle of 15 degrees with the first end face or the second end face, and the two pairs of angles of the rhomboid connecting buckle insert are 75 degrees.

[0044] For a reasonable design, the aforementioned limiting protrusions are located on the diagonally opposite sides of both sides of the diamond-shaped connecting buckle insert.

[0045] In order to enable the second end of the connecting buckle to connect to different items according to different usage needs, the second end of the connecting buckle is fixedly connected to the first end of the extension webbing 2 through the process of insert injection molding. The second end of the extension webbing 2 is connected to the hook or clip 3, and the phone case (with the phone placed in the phone case), work nameplate, etc. can be hung through the hook or clip.

[0046] The connecting buckle insert piece is provided with two strip-shaped holes A9 as process holes during injection molding.

[0047] The adjusting buckle insert piece B1 is detachably connected with the adjusting buckle B through buckling, or is detachably connected with the adjusting buckle B through screws, or is detachably connected with the adjusting buckle B through interference fit.

[0048] Specifically, the adjusting buckle insert piece B1 is cuboid, the adjusting buckle is provided with a rectangular notch B2 for mounting the adjusting buckle insert piece, the side of the adjusting buckle insert piece is provided with a limiting convex strip B3, the side wall of the rectangular notch is provided with a limiting recess B4 corresponding to the limiting convex strip B3, and after the adjusting buckle insert piece B1 is inserted into the rectangular notch B2, the relative fixing of the adjusting buckle insert piece B1 and the adjusting buckle B is realized through the limiting of the limiting convex strip B3 by the limiting recess B4.

[0049] The adjusting buckle is a rectangular frame, two partition strips B5 are arranged in the rectangular frame, the first channel B6 and the second channel B7 for the passing of the webbing 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 piece is clamped in the rectangular notch, the second end 102 of the webbing is vertically embedded and fixed on the back of the adjusting buckle insert piece, the webbing 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 the figure). Figure 3

[0050] The rectangular notch is a rectangular recess, the rectangular recess is arranged on the front of the adjusting buckle, the adjusting buckle insert piece is clamped into the rectangular recess from the front of the adjusting buckle, the limiting recess is arranged close to the back of the adjusting buckle, and the second end of the webbing is vertically embedded and fixed on the back of the adjusting buckle insert piece.

[0051] The structure of the hanging belt connecting buckle structure makes the first end of the webbing and the second end of the webbing not need to be sewn after being bent out of a section when being connected with the connecting buckle and the adjusting buckle, thereby saving the cost of a section of the webbing and the process and time of sewing the end part, and also making the hanging belt more simple and beautiful; in addition, it is also beneficial to make the adjustment of the length of the hanging belt more smooth (the specific reason is that the extra section of the webbing is close to the other webbing close to it, thereby increasing the friction force of pulling and adjusting, and affecting the smoothness of adjusting the length of the hanging belt).

[0052] The above only describes preferred embodiments of the utility model and is not used for limiting the utility model, and the utility model can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model.​
