[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0043] Directional terms mentioned in this invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only used with reference to the directions of the drawings. The directional terms used are used to illustrate and understand the invention, and are not intended to limit the invention.
[0044] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.
[0045] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0046] Conventional buckles typically include a female buckle and a male buckle, each connecting two cords. The female buckle has a hanging ring, while the male buckle has a hook. The hook and the hanging ring are detachably connected to connect and disconnect the two cords. When the two cords are loose, the hook easily detaches from the hanging ring, causing the two cords to separate, which is extremely inconvenient to use.
[0047] The following is a preferred embodiment of a waist belt provided by the present invention that can solve the above technical problems.
[0048] A preferred embodiment of the present utility model provides a waist belt comprising two ropes and a novel buckle.
[0049] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The new buckle comprises a female buckle 1 and a male buckle 2. The female buckle 1 is provided with a first direction ( Figure 4 The female connecting portion 11 and the connecting strip 12 are arranged in the x direction (the same below). The female connecting portion 11 is provided with a female through-hole 111, wherein a rope is connected to the female connecting portion 11 through the female through-hole 111. The connecting strip 12 is provided with a limiting groove 121, which is provided in the second direction ( Figure 4 The two ends of the limiting groove 121 are both open, and the limiting groove 121 is provided with a third direction ( Figure 4 The plug-in port 1211 is connected to the openings at both ends of the second direction of the limiting groove 121. The first direction, the second direction and the third direction are perpendicular to each other.
[0050] Please refer to Figure 6 The male fastener 2 is provided with a male connecting portion 21 and a receiving groove 22 arranged along the first direction. The male connecting portion 21 is provided with a male through-hole 211, and another rope is connected to the male connecting portion 21 through the male through-hole 211. The receiving groove 22 passes through a side surface of the male fastener 2 facing away from the male connecting portion 21 in the first direction and two opposite side surfaces in the third direction. A connecting column 23 is provided in the receiving groove 22, and both ends of the connecting column 23 are respectively fixed to the two side walls of the receiving groove 22 in the second direction, and the connecting column 23 is spaced apart from a side wall of the receiving groove 22 in the first direction.
[0051] Among them, the connecting column 23 can be inserted into the limiting groove 121 from the plug-in port 1211, and can be detached from the limiting groove 121 from the plug-in port 1211, and the connecting column 23 can rotate in the limiting groove 121. When the female fastener 1 and the male fastener 2 are connected through the connecting column 23 and the limiting groove 121, and are arranged along the first direction, the size of the plug-in port 1211 along the first direction is smaller than the size of the connecting column 23 along the first direction, so as to limit the connecting column 23 in the limiting groove 121.
[0052] When the female fastener 1 and the male fastener 2 need to be connected, the female fastener 1 and the male fastener 2 are first held at an appropriate angle, and then the connecting post 23 enters the limiting groove 121 from the insertion opening 1211. The male fastener 2 is then rotated, and the connecting post 23 rotates accordingly. When the female fastener 1 and the male fastener 2 are arranged in a straight strip along the first direction, the insertion opening 1211 can limit the connecting post 23 in the limiting groove 121, thereby making it difficult for the connecting post 23 to separate from the connecting strip 12, and further making it difficult for the female fastener 1 and the male fastener 2 to separate. When it is necessary to separate the female fastener 1 and the male fastener 2, the male fastener 2 is rotated in the opposite direction, and the connecting post 23 also rotates accordingly. When the female fastener 1 and the male fastener 2 maintain an appropriate angle again, the connecting post 23 is pulled out from the insertion opening 1211, thereby separating the connecting post 23 from the connecting strip 12, and further separating the female fastener 1 and the male fastener 2. The novel buckle and belt of the utility model are such that when the female buckle 1 and the male buckle 2 are assembled, the two are not easily separated by mistake, and the assembly and disassembly operations are simple, making them easy to use. In addition, the female buckle 1 and the male buckle 2 have simple structures and are easy to process and manufacture.
[0053] Please refer to Figure 7 The outer peripheral surface of the connecting column 23 includes two convex arc surfaces 231, and the two convex arc surfaces 231 are in the fourth direction ( Figure 7 The fourth direction is perpendicular to the second direction, and the angle θ between the fourth direction and the third direction is an acute angle. With the above-described structure, the two convex curved surfaces 231 can be inserted into and out of the insertion opening 1211, facilitating the connection column 23 to enter and exit the limiting slot 121 and facilitating the rotation of the connection column 23 within the limiting slot 121. This also facilitates user identification of how to assemble and disassemble the female fastener 1 and male fastener 2. When assembling and disassembling the female fastener 1 and male fastener 2, the two convex curved surfaces 231 can be aligned with the insertion opening 1211, eliminating the need for excessive wrist twisting. In other embodiments, the two convex curved surfaces 231 can be arranged relative to each other along the first direction. In this case, when assembling and disassembling the female fastener 1 and male fastener 2, the male fastener 2 can be rotated 90° counterclockwise or clockwise to align the two convex curved surfaces 231 with the insertion opening 1211.
[0054] Please continue to refer to Figure 7 The angle θ between the fourth direction and the third direction is 70°-80°. By simply rotating the male fastener 2 counterclockwise or clockwise by 70°-80°, the two convex arc surfaces 231 can be aligned with the insertion opening 1211, respectively, facilitating user operation. Furthermore, when the female fastener 1 and the male fastener 2 are connected in a straight strip, the connecting post 23 is unlikely to fall out of the retaining groove 121. Preferably, the angle between the fourth direction and the third direction is 75°.
[0055] Please continue to refer to Figure 7 The outer circumference of the connecting post 23 includes two flat surfaces 232. The two flat surfaces 232 are parallel to each other and parallel to the fourth direction. With this structure, when the female fastener 1 and the male fastener 2 are assembled, the connecting post 23 is unlikely to fall out of the retaining groove 121, thereby preventing the female fastener 1 and the male fastener 2 from being separated.
[0056] Please refer to Figure 5 and Figure 7 The difference between the dimension A of the plug opening 1211 along the first direction and the distance A1 between the two straight surfaces 232 is greater than 0.2 mm and less than 0.4 mm. The difference between the maximum dimension B of the limiting groove 121 along the first direction and the maximum distance B1 between the two convex curved surfaces 231 is greater than 0.2 mm and less than 0.4 mm. The dimension of the plug opening 1211 along the first direction is smaller than the maximum dimension of the limiting groove 121 along the first direction. The above structure makes it easier for the connecting post 23 to enter and exit the plug opening 1211. At the same time, when the female fastener 1 and the male fastener 2 are connected, the connecting post 23 is not easily separated from the limiting groove 121, thereby preventing the female fastener 1 and the male fastener 2 from separating. Preferably, the difference between the dimension A of the plug opening 1211 along the first direction and the distance A1 between the two straight surfaces 232 is 0.3 mm, and the difference between the maximum dimension B of the limiting groove 121 along the first direction and the maximum distance B1 between the two convex curved surfaces 231 is 0.3 mm.
[0057] In other embodiments, the cross-section of the connecting post 23 may be elliptical, with its long diameter parallel to the fourth direction, so that the two convex arc surfaces 231 can more easily enter and exit the plug-in port 1211 , facilitating the insertion and removal of the connecting post 23 .
[0058] Please refer to Figure 4 The limiting groove 121 includes two concave arc surfaces 1212, which are arranged opposite each other in the first direction. The curvature of the two concave arc surfaces 1212 is the same as that of the two convex arc surfaces 231. The two convex arc surfaces 231 cooperate with the two concave arc surfaces 1212 to make the connecting post 23 rotate more smoothly in the limiting groove 121.
[0059] Please refer to Figure 4 and Figure 6 Both the female connector 11 and the male fastener 2 are sheet-shaped, with their thickness oriented in the third direction. Female through-holes 111 extend through both sides of the female connector 11 in the thickness direction. Male through-holes 211 extend through both sides of the male connector 21 in the thickness direction. The combined female and male fasteners 1 and 2 form a sheet-like shape that is less likely to irritate the skin, improving the user experience.
[0060] The method of using the waist belt of the preferred embodiment of the utility model is as follows:
[0061] When connecting two ropes, the male fastener 2 is first tilted about 75 degrees relative to the female fastener. The connecting post 23 then enters the limiting groove 121 from the insertion opening 1211 through a convex arc surface 231. The male fastener 2 is then rotated, and the connecting post 23 rotates accordingly. When the female fastener 1 and the male fastener 2 are arranged in a straight strip along the first direction, the insertion opening 1211 can limit the connecting post 23 in the limiting groove 121, thereby making it difficult for the connecting post 23 to separate from the connecting strip 12, and further making it difficult for the female fastener 1 and the male fastener 2 to separate. When the two ropes need to be disconnected, the male fastener 2 is rotated in the opposite direction, and the connecting post 23 also rotates accordingly. When the male fastener 2 is tilted about 75 degrees relative to the female fastener, the connecting post 23 is pulled out of the insertion opening 1211 through another convex arc surface 231, thereby separating the connecting post 23 from the connecting strip 12, and further separating the female fastener 1 and the male fastener 2.
[0062] This completes the method for using the waist belt of this preferred embodiment.
[0063] Please refer to Figure 8 and Figure 9 The second preferred embodiment of the present invention provides a novel fastening mechanism. This differs from the first embodiment in that two connecting bars 12 are provided, spaced apart along the second direction. The retaining grooves 121 of the two connecting bars 12 face opposite directions, with their insertion and removal openings 1211 oriented in opposite directions. The male fastener 2 must deviate from the first direction as well as the second direction to disengage the connecting post 23 from the retaining groove 121. This makes it much less likely that the assembled female and male fasteners 1 and 2 will be accidentally separated.
[0064] The other structures of this embodiment are similar to those of the first embodiment and will not be described again here.
[0065] In the novel buckle and belt of the present utility model, when the female and male fasteners are arranged in a straight strip along a first direction, the insertion and removal opening can restrain the connecting post in the retaining groove, thereby preventing the connecting post from separating from the connecting strip, and further preventing the female and male fasteners from separating. When the female and male fasteners are assembled, the new buckle and belt of the present utility model are difficult to accidentally separate, and the assembly and disassembly operations are simple, making them easy to use. Furthermore, the simple structures of the female and male fasteners facilitate processing and manufacturing.
[0066] To sum up, although the present invention has been disclosed as above in terms of preferred embodiments, the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes based on the concept of the technical solution of the present invention, should be covered by the scope of protection of the present invention.
