Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a novel multi-strand ladder buckle. Background Technology

[0002] Ladder buckles are commonly used on clothing webbing or backpack straps to adjust the fit of the webbing and backpack. Existing ladder buckles typically adjust their tension by connecting two webbing straps to either end. The tension is adjusted by manipulating one end of the strap with a finger, changing the angle between the strap and the buckle. For example, Chinese utility model patent CN217658438U discloses an ergonomic duckbill ladder buckle, which uses a first webbing strap and a second webbing strap at each end. This ergonomic duckbill ladder buckle includes a main body, a duckbill portion at one end of the main body, and a first fixing post on one side of the duckbill portion. The duckbill portion includes an arcuate portion on one side of the first fixing post and a flat portion on one side of the arcuate portion. The arcuate portion smoothly slopes down at both ends and connects to the two ends of the flat portion. The ergonomic duckbill ladder buckle provided by this utility model forms a concave surface on one side of the duckbill portion that fits the human finger through the arc portion and the flat portion. The ergonomic duckbill ladder buckle conforms to ergonomic design and will not cause discomfort or pain to the fingers during long-term use, thus improving user comfort.

[0003] Conventional ladder buckles use two webbing straps to connect them, but in actual use, it is often necessary to separate one of the webbing straps to achieve a secure fastening. Summary of the Invention

[0004] In view of this, the present invention provides a novel multi-strand ladder buckle to solve the above-mentioned technical problems.

[0005] A novel multi-strap ladder buckle includes a buckle body, a first connecting portion disposed on the buckle body, and a second connecting portion spaced apart from the first connecting portion. The buckle body includes two symmetrically arranged support portions, a connecting portion perpendicularly connecting the two support portions, a top abutment located at one end of each support portion, and a lifting portion located at the other end of each support portion. The two support portions are spaced apart from each other and arranged parallel to each other, exhibiting axial symmetry. Each support portion has an arc-shaped edge along its length on one side in the width direction and a straight edge on the other side, making the support portion overall arch-shaped. The first connecting portion is a rod-shaped structure disposed between the connecting portion and the top abutment, and is parallel to the connecting portion. Both ends are vertically fixed to the support portion and connected to the side of the support portion near the arc-shaped edge. The second connecting portion is disposed between the connecting portion and the lifting portion, and includes a fixing portion parallel to the connecting portion and a multi-strap portion disposed on the central axis of the fixing portion. The fixing part is a rod-shaped structure, with both ends vertically fixed to the support part and located on the side of the support part near the arc-shaped edge. The strip part connects the midpoint of the connecting part, the fixing part, and the lifting part. The thickness of the strip part at the connection with the connecting part is less than its thickness at the connection with the lifting part.

[0006] Furthermore, the connecting part is a rod-shaped structure located between the two supporting parts and is perpendicular to the two supporting parts respectively. The connecting part is disposed on the side of the supporting part near the straight edge.

[0007] Furthermore, the abutment top is connected to one end of the two support portions and is arranged parallel to the connecting portion.

[0008] Furthermore, the lifting portion is disposed at the other end of the support portion away from the abutment top, and is disposed parallel to the connecting portion.

[0009] Furthermore, the lifting part has a duckbill-shaped structure and a concave surface is formed on the side of the arc-shaped edge away from the support part.

[0010] Furthermore, the concave surface of the lifting part is provided with multiple parallel anti-slip textures.

[0011] Furthermore, the segmented section is a sheet-like structure.

[0012] Furthermore, the first connecting portion is provided with an inclined surface facing the connecting portion.

[0013] Compared with the prior art, the novel webbing ladder buckle provided by this utility model provides a second connecting part and a webbing part between the fixing part, the connecting part and the lifting part, which divides the fixing part into two equal parts, allowing two webbings to pass through and connect respectively, thus serving as a webbing splitter and making it convenient for users to split the webbing on one side for use.

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 3 The diagram shown is a structural schematic of the novel split-belt ladder buckle provided by this utility model. The novel split-belt ladder buckle includes a buckle body 10, a first connecting portion 20 disposed on the buckle body 10, and a second connecting portion 30 spaced apart from the first connecting portion 20. It is conceivable that the novel split-belt ladder buckle also includes other functional modules such as a logo module, a webbing module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0019] The buckle body 10 can be made of plastic injection molding and integrally formed. It includes two symmetrically arranged support parts 11, a connecting part 12 that vertically connects the two support parts 11, a top abutment 13 located at one end of the support part 11, and a lifting part 14 located at the other end of the support part 11.

[0020] The two support portions 11 are spaced apart from each other and arranged in parallel, and are axially symmetrical, serving as the support structure for the buckle body 10. Each support portion 11 is arc-shaped. Specifically, the support portion 11 has an arc-shaped edge on one side along the length direction in the width direction and a straight edge on the other side, making the support portion 11 as a whole appear bow-shaped. This arc-shaped structure facilitates fastening the straightened shoulder strap, allowing the user to adjust the length of the shoulder strap by changing the straightening angle of the shoulder strap, or by lifting one end of the support portion 11 to adjust the length of the webbing on one side. The specific methods and structures are described in Chinese Utility Model No. CN217658438U, "An Ergonomic Duckbill Ladder Buckle," and will not be described in detail here.

[0021] The connecting portion 12 is a rod-shaped structure located between the two supporting portions 11 and perpendicular to both supporting portions 11. While connecting the two supporting portions 11, it also serves to support and stabilize the frame structure. The connecting portion 12 is positioned on the side of the supporting portion 11 near its straight edge, offset from the first connecting portion 20 and the second connecting portion 30, facilitating the connection of the webbing. This will be described in detail below in conjunction with the first connecting portion 20 and the second connecting portion 30.

[0022] The abutment 13 connects to one end of the two support portions 11 and is arranged parallel to the connecting portion 12 to form a through hole for the fastener through which the webbing passes. At the same time, when the webbing is looped on the first connecting portion 20 and straightened, the abutment 13 will press and rub against the surface of the webbing to prevent the webbing from moving. This will be described in detail below in conjunction with the first connecting portion 20.

[0023] The lifting part 14 is disposed at the other end of the support part 11 away from the top 13, and is arranged parallel to the connecting part 12. The lifting part 14 has a duckbill-shaped structure, and a concave surface is formed on the side of the arc-shaped edge away from the support part 11 to facilitate finger snapping. This is used to change the angle between the webbing and the second connecting part 30 by snapping the lifting part 14, thereby reducing the friction between the buckle body 10 and the webbing surface and adjusting the webbing length. The specific details are described in Chinese Utility Model No. CN217658438U, "An Ergonomic Duckbill Ladder Buckle", and will not be described in detail here. In addition, multiple parallel anti-slip textures can be provided on the concave surface of the lifting part 14 to enhance the tactile feel and increase the friction during use, making it easier for the user to touch and pull.

[0024] The first connecting portion 20 is a rod-shaped structure disposed between the connecting portion 12 and the abutment 13, and is arranged parallel to the connecting portion 12. Both ends are vertically fixed to the support portion 11. Specifically, it is connected to the side of the support portion 11 near the arc-shaped edge, thereby misaligning with the connecting portion 12 to facilitate abutment and friction against the webbing when it is straightened. The first connecting portion 20 has an inclined surface facing the connecting portion 12, so that when the webbing passes over the first connecting portion 20, it is tightened along the inclined surface in a direction away from the connecting portion 12.

[0025] The second connecting part 30 is disposed between the connecting part 12 and the lifting part 14, and includes a fixing part 31 disposed parallel to the connecting part 12, and a strip part 32 disposed on the central axis of the fixing part 31.

[0026] The fixing part 31 is a rod-shaped structure with both ends vertically fixed to the support part 11 and located on the side of the support part 11 near the arc edge, thereby misaligning with the connecting part 12, so as to generate resistance and friction on the webbing when the webbing is straightened.

[0027] The webbing section 32 can be a sheet-like structure, connecting the midpoints of the connecting section 12, the fixing section 31, and the lifting section 14, thereby dividing the fixing section 31 into two parts from the midpoint, allowing two webbings to be fitted simultaneously. The thickness of the webbing section 32 at the connection with the connecting section 12 is less than the thickness at the connection with the lifting section 14, so that after the two webbings are connected to the fixing section 31, there is an angle along the stretching direction, meaning the two webbings will gradually separate.

[0028] Compared with the prior art, the novel webbing ladder buckle provided by this utility model provides a second connecting part 30 and a webbing part 32 between the fixing part 31, the connecting part 12 and the lifting part 14, which divides the fixing part 31 into two parts, allowing two webbings to pass through and connect respectively, thus playing the role of webbing separation, making it convenient for users to separate the webbing on one side for use.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
