Description

Technical Field

[0001] This utility model relates to a hanging strap, particularly a hanging strap whose length can be adjusted according to usage needs. Background Technology

[0002] The strap is hung around the user's neck to hang items, such as name tags, mobile phones, etc. Due to the different heights and usage needs of different users, its length needs to be adjusted.

[0003] The applicant's Chinese patent applications for "Hanging Strap (III)" (publication number CN308589765S) and "Hanging Strap (V-type)" (publication number CN308493082S) do not allow for length adjustment.

[0004] The applicant's 2023 application for a "webbing safety buckle" (publication number CN219047592U) includes a male buckle and a female buckle. The male buckle is composed of an upper cover plate and a lower buckle plate, which are ultrasonically welded together. The male buckle has a first spike with a pair of interlocking structures for fixing the webbing inside, and one end of the male buckle has an insertion protrusion. The female buckle is composed of an upper cover plate and a lower cover plate, which are ultrasonically welded together. The female buckle has a second spike with a pair of interlocking structures for fixing the webbing inside, and one end of the female buckle has an insertion cavity for the insertion protrusion to extend into. A matching elastic deformation locking structure is provided between the insertion cavity and the insertion protrusion. The male and female buckles of this webbing safety buckle are fused together by ultrasonic welding. Although this method can ensure the connection strength and the connection with the webbing, the length of the strap using this structure cannot be adjusted.

[0005] Another search revealed a Chinese patent, CN219146936U, entitled "A Hanging Strap," which includes a connecting piece with an opening at the top. The connecting piece has a detachable buckle in the center, used to fasten two hanging straps. One strap has a first buckle hole at its end, which detachably fastens an extension strap outwards. The extension strap has a second buckle hole, which detachably fastens other extension straps in the opposite direction. The other hanging point has an adjusting pin buckle at its end, with a limiting pin. Although this patent allows for two adjustable lengths of the hanging strap, making it suitable for both children and adults, the adjustment process is cumbersome and inconvenient.

[0037] 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

[0038] 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.

[0039] One embodiment of the adjustable-length hanging strap of this utility model 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...) Figure 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.

[0040] The second embodiment of the adjustable length hanging strap of this utility model 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.

[0041] 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.

[0042] 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.

[0043] 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.).

[0044] The method of using the adjustable length strap in the above embodiment: To extend the length of the strap (i.e., to make...) Figure 2The 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.

[0045] 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.

[0046] To prevent items (such as work permits) hanging on the lower end of the strap from twisting and tilting when the item is relatively light, the first end of the aforementioned connecting buckle A is provided with a groove A2 that passes through the groove A2 and is located in the horizontal direction (the direction perpendicular to the direction the webbing enters the connecting buckle, such as...). Figure 9 As shown, the first through groove A5 and the second through groove A6 are misaligned. A connecting buckle plate A7 is provided in the groove A2, directly opposite the first through groove A5. The connecting buckle plate A7 is sheet-shaped, with both sides integrally connected to the connecting buckle. The side of the connecting buckle plate away from the first through groove is a bevel A8. The webbing enters through the first through groove A5, passes around the connecting buckle plate A7, and then exits through the first through groove A5. The webbing 1 is guided and supported by the bevel A8 of the connecting buckle plate, causing the webbing exiting the connecting buckle to tilt to one side. Figure 9 (As shown on the left), the first end 101 of the webbing passes through the second through groove A6 and is fixedly connected to the connecting buckle insert (before the first end 101 of the webbing is injection molded, it needs to pass through the second through groove A6 and enter the groove and extend a certain length for subsequent injection molding of the insert), the webbing that passes through the second through groove is inclined to the other side ( Figure 9 (as shown on the right), so that the webbing passing through the first through groove and the second through groove is V-shaped.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The aforementioned connecting buckle insert has two strip holes A9, which serve as process holes during injection molding.

[0053] The adjusting buckle insert B1 and the adjusting buckle B are detachably connected by a snap-fit, or by a screw, or by an interference fit.

[0054] Specifically, the aforementioned adjusting buckle insert B1 is rectangular in shape, and the adjusting buckle has a rectangular slot B2 for installing the adjusting buckle insert. The side of the adjusting buckle insert is provided with a limiting protrusion B3, and the side wall of the rectangular slot is provided with a limiting groove B4 corresponding to the limiting protrusion. After the adjusting buckle insert B1 is inserted into the rectangular slot B2, the limiting groove B4 limits the limiting protrusion B3, thereby achieving relative fixation between the adjusting buckle insert B1 and the adjusting buckle B.

[0055] The aforementioned adjusting buckle is a rectangular frame with two spacers B5 within it. The spacers B5 and the rectangular frame respectively form a first channel B6 and a second channel B7 for the webbing to pass through. A rectangular slot B2 is formed between the two spacers. The adjusting buckle insert is secured in the rectangular slot. The second end 102 of the webbing is vertically embedded and fixed to the back of the adjusting buckle insert. The webbing passes through the first channel B6 from the back of the adjusting buckle, passes through the two spacers B5, and then passes through the second channel B7 from the front of the adjusting buckle to the back of the adjusting buckle (e.g., ...). Figure 3 (As shown).

[0056] The rectangular slot is a rectangular recessed groove. The rectangular recessed groove is located on the front of the adjusting buckle. The adjusting buckle insert is inserted into the rectangular slot from the front of the adjusting buckle. The limiting groove is located on the back of the adjusting buckle. The second end of the webbing is vertically embedded and fixed on the back of the adjusting buckle insert.

[0057] The adjustable-length hanging strap of this invention eliminates the need for an extra section of webbing to be bent and sewn when connecting the first and second ends of the webbing to the connecting buckle and adjusting buckle (i.e., a spacer is set on the connecting buckle and adjusting buckle, and the first or second end of the webbing passes through the spacer and is bent 180 degrees before being sewn at the end). This saves the cost of an extra section of webbing and the process and time of sewing the end, making the hanging strap simpler and more aesthetically pleasing. In addition, it also facilitates smoother adjustment of the hanging strap length (specifically, when adjusting the hanging strap length, an extra section of webbing would increase the friction of pulling and adjusting because it is close to other webbing sections, affecting the smoothness of the adjustment).

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are permitted.
