detailed description

The cord buckle of the present invention includes a body having elasticity, the body having a passage therethrough for the passage of the rope, the passage having an elastic piece extending from the inner wall of the passage toward the center of the passage, the elastic piece There is a rope hole that contracts when the main body is opened when the main body is pressed, and the elastic piece has a reinforcing structure for increasing the frictional force between the rope hole and the rope. When the elastic piece is in a generally unstressed state, the internal aperture is narrower than the diameter of the rope, and the rope is clamped by the interference and friction of the elastic piece; when the body is pressed, the elastic piece will increase the internal aperture due to the deformation. Let the rope pass freely, so that the interference and friction disappear and the loosening function is achieved. The rope buckle of the present invention is described in detail below in conjunction with specific embodiments.

As shown in Fig. 1, Fig. 2a, Fig. 2b, Fig. 3a and Fig. 3b, in an embodiment in which the cord of the present invention is buckled, the body 1 having elasticity is substantially elliptical in shape, having a rope passage 11 penetrating the body 1. The middle portion of the passage 11 extends from the inner wall of the passage 11 toward the center of the passage to form an elastic piece 12 having an elastic hole 12 which is opened when the main body 1 is pressed, and a rope hole 121 which is contracted when the main body 1 is loosened, in order to reinforce the rope hole 121 and the rope The frictional force makes the rope fixed more firmly, and the elastic piece 12 has a reinforcing structure for increasing the frictional force between the rope hole 121 and the rope. In the present embodiment, the reinforcing structure is that the elastic piece 12 extends toward the passage 11. The direction is convex, as shown in FIG. 3b, when the rope penetrates the rope hole 121 and pulls the rope in the direction of the arrow, the elastic piece 12 is deformed in the direction of the arrow by the rope, and the rope hole 121 is reduced during the deformation, the elastic piece 12 Squeeze the rope so that the friction between the rope hole 121 and the rope is increased, and the rope is difficult to be pulled. When the rope is pulled in the opposite direction to the direction indicated by the arrow, the rope hole 121 is expanded, making the rope pulling easier. When it is necessary to adjust the fixed state or the fixed position of the rope, the main body 1 can be pressed to open the rope hole 121. After the adjustment, the main body 1 is loosened, and the rope hole 121 shrinks and catches the rope to fix the rope.

In the present embodiment, the main body 1 has an ear piece 13 extending outward from the main body 1, and the ear piece 13 has a through hole 131 for the passage of the string, and the rope passes through the hole 131 to fix the rope buckle. Clothes, backpacks, etc. require a rope to buckle. Figures 4a and 4b show a schematic view of the rope buckle of the present embodiment applied to a garment. In practical applications, the ear piece 13 may also be provided with a hole without a hole, and the ear piece 13 may be directly sewn to a place where it is needed, or a sewing groove for a needle thread may be provided on the ear edge 13 or Sewing holes. The sewing slot is provided with a shallow groove on the ear piece for sewing, and the sewing hole is provided with a row of small holes on the ear piece to facilitate the sewing of the needle thread.

In the present embodiment, the rope hole 121 has an elliptical shape, and may actually be a "one" shape.

In the present embodiment, in order to more conveniently press the main body 1, the main body 1 is provided with a recess 14 having a non-slip function, and a better hand feeling can be obtained, and in practice, it can also be provided as a projection.

As shown in Fig. 5, Fig. 6a, Fig. 6b, Fig. 7a and Fig. 7b, a second embodiment of the rope buckle of the present invention, the body 1 having elasticity is substantially elliptical in shape, having a rope passage 11 penetrating the body 1. The middle portion of the passage 11 extends from the inner wall of the passage 11 toward the center of the passage to form an elastic piece 12 having an elastic hole 12 which is opened when the main body 1 is pressed, and a rope hole 121 which is contracted when the main body 1 is loosened, in order to reinforce the rope hole 121 and the rope The frictional force makes the rope fixed more firmly, and the elastic piece 12 has a reinforcing structure for increasing the frictional force between the rope hole 121 and the rope. In the present embodiment, the reinforcing structure is expressed at the root of the elastic piece 12. The thickness of 122 is greater than the thickness of the elastic sheet 12 at the edge region 123 of the cord hole 121. As shown in FIG. 7b, the section of the elastic sheet 12 extending in the direction of the passage 11 (the area surrounded by the broken line frame 124) is substantially an isosceles trapezoid. The reinforcing structure thickened at the root portion 122 of the elastic piece 12 makes the elastic piece 12 less susceptible to deformation, and this structure causes the elastic piece 12 to not become inclined when the elastic piece 12 is pulled to one side when the rope is pulled, thereby causing the rope hole 121 to become large. To make the rope hole 121 to the rope There is greater friction, which makes the rope more secure. Since the cross section of the elastic piece 12 is an isosceles trapezoid, the effect is the same regardless of the direction in which the rope is pulled.

8a and 8b show the shape of the rope hole 121 when the main body 1 is not pressed, and the rope hole 121 catches the rope 2 to fix the rope 2. 9a and 9b show a change in the shape of the rope hole 121 when the body 1 is pressed, and the rope hole 121 is opened so that the rope 2 can freely move within the rope hole 121.

In the present embodiment, the main body 1 has an ear piece 13 which is formed to extend outward from the main body 1, and the ear piece 13 can be directly sewn on the clothes. Figures 10a and 10b show a schematic view of the rope buckle of the present embodiment applied to a garment. In practical applications, the ear piece may also adopt the structure of the ear piece in the first embodiment, or a sewing groove or a sewing hole through which the needle thread passes may be provided on the ear piece.

In the present embodiment, in order to more conveniently press the main body 1, the main body 1 is provided with an elliptical recess 141, and a plurality of small elliptical recesses 142 are sleeved in the circular arc-shaped recess 141, which has a non-slip function. Can get a better feel, beautiful and practical. It can also be set as a bump in practical applications.
