Description

Technical Field

[0001] This invention relates to the field of fastener technology, and specifically to a webbing tightening buckle for tightening and adjusting webbing. Background Technology

[0002] Traditional D-ring buckles are widely used in bags, clothing, outdoor equipment, and other applications requiring webbing tightening. Their structure is typically a simple frame with a central crossbar, relying on the friction of the webbing to achieve a locking mechanism. However, existing technology has the following drawbacks: 1. The resistance to threading the webbing is high, and it is difficult to fold the webbing back and thread it, making the operation cumbersome and inefficient. 2. The narrow pressure area and uneven force cause the webbing to twist into a state where one side bulges and the other side sinks after tightening, resulting in poor flatness and appearance. 3. The locking stability is insufficient, it is easy to loosen, and often requires additional sewing to fix it, which is inconvenient to use.

[0003] Therefore, it is necessary to improve the structure of existing webbing fasteners to overcome the above-mentioned drawbacks. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of traditional D-ring buckles, such as difficulty in threading the strap, uneven tightening, unreliable locking, and the need for edge reinforcement. The invention provides a webbing tightening buckle that allows for smooth threading, even tightening, stable locking, and eliminates the need for edge sewing.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: a webbing tightening buckle, including a tightening buckle body (1), a central crossbar (2), a webbing inlet and outlet one (3), a webbing inlet and outlet two (5), a webbing inlet and outlet groove one (41), a webbing inlet and outlet groove two (42), an auxiliary guide groove one (31), and an auxiliary guide groove two (51); the central crossbar (2) is fixed in the middle of the tightening buckle body (1); the webbing inlet and outlet one (3) is connected to the auxiliary guide groove one (31), and the webbing inlet and outlet two (5) is connected to the auxiliary guide groove two (51); the webbing passes through the webbing inlet and outlet one (3) and the webbing inlet and outlet groove one (41) in sequence, passes around the central crossbar (2), enters the webbing inlet and outlet groove two (42) and extends out from the webbing inlet and outlet two (5), passes around the bound object and then turns back, and is guided back through the auxiliary guide groove two (51) and the auxiliary guide groove one (31) to achieve automatic locking and tightening.

[0006] Furthermore, the webbing inlet / outlet one (3) and webbing inlet / outlet two (5) are widened pressure rope channels to keep the webbing on the same plane without twisting or depression. Furthermore, the auxiliary guide groove one (31) and auxiliary guide groove two (51) are flared guide structures to reduce the resistance of webbing insertion and improve the smoothness of re-threading. Furthermore, the webbing inlet / outlet groove one (41) and webbing inlet / outlet groove two (42) are symmetrically arranged to form a stable folding path in conjunction with the central crossbar (2). Furthermore, the tightening buckle is integrally molded, with high structural strength and dimensional stability.

[0007] The beneficial effects of this invention are as follows: 1. An auxiliary guide groove is added, which makes the webbing threading and folding smooth, and the webbing can be threaded and tightened quickly without tools; 2. The pressure area is widened, the webbing is stressed evenly, and the surface is flat and free of dents or twists after tightening, resulting in a more aesthetically pleasing appearance. 3. The combination of multiple folds and channel limiting provides sufficient friction, allowing for stable locking without the need for seams and preventing loosening; 4. Simple structure, easy to mold, and highly versatile, suitable for various scenarios such as bags, backpacks, pet leashes, and outdoor equipment. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] like Figure 1 As shown in Figure 6, a webbing tightening buckle includes a tightening buckle body (1), a central crossbar (2), a webbing inlet / outlet one (3), a webbing inlet / outlet two (5), a webbing inlet / outlet one (41), a webbing inlet / outlet two (42), an auxiliary guide groove one (31), and an auxiliary guide groove two (51). The central crossbar (2) is integrally formed in the middle of the webbing tightening buckle body (1), dividing the inner cavity into left and right winding areas. The webbing inlet / outlet one (3) is connected to the auxiliary guide groove one (31), and the webbing inlet / outlet two (5) is connected to the auxiliary guide groove two (51); the auxiliary guide groove one (31) and the auxiliary guide groove two (51) are both outwardly expanding smooth guide openings, which significantly reduce the resistance of webbing insertion.

[0011] Threading path: The webbing enters through webbing inlet and outlet one (3), exits through webbing inlet and outlet one (41), goes around the middle crossbar (2) and then enters webbing inlet and outlet two (42), then extends out through webbing inlet and outlet two (5), goes around the object to be bound and then turns back, enters webbing inlet and outlet two (5) through auxiliary guide groove two (51), goes around the middle crossbar (2) again, and goes back through webbing inlet and outlet one (41) and auxiliary guide groove one (31) to webbing inlet and outlet one (3), completing the closed-loop tightening.

[0012] The webbing inlet / outlet 1 (3) and webbing inlet / outlet 2 (5) adopt a widened pressure rope channel design, with the width adapted to the webbing thickness, so that the webbing remains on the same plane under bending and stress, without warping or denting. The surface of the middle crossbar (2) is smooth, reducing webbing wear and improving service life. The whole is made of hard plastic or metal in one piece, with a stable structure and strong durability.

[0013] This invention is not limited to the specific embodiments described above. Any modifications or improvements made by those skilled in the art without departing from the concept of this invention shall fall within the protection scope of this invention.
