[0026] Embodiments of the present invention will be described with reference to Figures 1 to 3. Here, Figure 1 is a perspective view of an embodiment of the quick-release cable drum stopper according to the present invention. Figure 2 is a perspective view showing the quick-release cable drum stopper according to the present invention in contact with the ground and the outer edge of the flange. Furthermore, Figure 3 is a perspective view of the quick-release cable drum stopper according to the present invention installed on the outer surface of the flange.

[0027] As shown in Figures 1 to 3, the quick-release cable drum stopper 1 comprises a flange contact portion 20, an anti-slip portion 30, a first connection portion 40, and a mounting portion 50. The first connection portion 40 is connected to the flange contact portion 20 and the anti-slip portion 30.

[0028] The quick-release cable drum stopper 1 is formed as a block-like structure having a first surface 10A and a second surface 10B. The flange contact portion 20, the anti-slip portion 30, and the first connecting portion 40 are located between the first surface 10A and the second surface 10B of the quick-release cable drum stopper 1, with the second surface 10B located on the opposite side of the first surface 10A.

[0029] The cable drum flange 500, used for contacting or mounting to the quick-release cable drum stopper 1, comprises a cable drum body 510 and two flanges 520. The two flanges 520 are attached to both sides of the cable drum body 510. A portion of the cable drum body 510, called the drum plate central portion 521, is located in the center of the outer surface 520A of the flanges 520.

[0030] As shown in Figure 2, when the quick-release cable drum stopper 1 comes into contact with the ground G and the outer edge 523 of the flange portion 520, the flange contact portion 20 comes into contact with a part of the outer edge 523 of the flange portion 520, the shape of a part of the flange contact portion 20 corresponds to a part of the outer edge 523 of the flange portion 520, and the anti-slip portion 30 comes into contact with the ground G.

[0031] Next, we will explain with reference to Figure 4. Here, Figure 4 is an assembly diagram of a first embodiment of a quick-release cable drum stopper attached to the outer surface of the flange portion according to the present invention.

[0032] Referring simultaneously to Figures 2 to 4, the mounting portion 50 is located on the first surface 10A of the quick-release cable drum stopper 1, the first surface 10A faces the outer surface 520A of the flange portion 520, and the mounting portion 50 is attached to the outer surface 520A of the flange portion 520.

[0033] Specifically, during installation, the quick-release cable drum stopper 1 is mounted between the central portion 521 of the drum plate and the inner edge 525 of the flange portion 520.

[0034] Furthermore, in some embodiments, the quick-release cable drum stopper 1 further comprises a second connecting portion 60. The second connecting portion 60 is connected to the flange contact portion 20 and the anti-slip portion 30 and is located on the opposite side of the first connecting portion 40.

[0035] Furthermore, when the quick-release cable drum stopper 1 is attached to the outer surface 520A of the flange portion 520, the first connecting portion 40 abuts against the inner edge 525 of the flange portion 520, and the second connecting portion 60 abuts against the central portion 521 of the drum plate.

[0036] Furthermore, the outer surface 520A of the flange portion 520 is provided with a plurality of spokes 530, which are located between the central portion 521 of the drum plate and the inner edge 525, and the mounting portion 50 engages with at least one of these spokes 530.

[0037] More specifically, the mounting portion 50 is a groove, the width of the spoke 530 is slightly greater than the width of the mounting portion 50, and the depth of the mounting portion 50 is slightly greater than the height of the spoke 530. Therefore, after engagement, they can fit together tightly to prevent them from falling out.

[0038] The explanation will be given with reference to Figure 5. Here, Figure 5 is an assembly diagram of a second embodiment of the quick-release cable drum stopper attached to the outer surface of the flange portion according to the present invention.

[0039] As shown in Figure 5, the spoke 530 has a first spoke 530A and a second spoke 530B, and the first spoke 530A and the second spoke 530B intersect each other. For example, the first spoke 530A is the inner edge 525 extending from the central part 521 of the drum plate, and the second spoke 530B surrounds the central part 521 of the drum plate in an annular shape, but this is just one example and is not limited to this.

[0040] Furthermore, the mounting portion 50 has a first groove 50A and a second groove 50B, the first groove 50A and the second groove 50B are connected to each other, the first groove 50A engages with the first spoke 530A, and the second groove 50B engages with the second spoke 530B.

[0041] Furthermore, the quick-release cable drum stopper 1 further comprises a plurality of studs or projections 70 extending from the second surface 10B and adjacent to the flange contact portion 20. When the flange contact portion 20 contacts the flange portion 520, the studs or projections 70 are attached to one side edge of the spoke 530 or the inner edge 525 of the flange portion 520, ensuring that the quick-release cable drum stopper 1 is less likely to loosen.

[0042] The explanation will be given with reference to Figure 6. Here, Figure 6 is an assembly diagram of a third embodiment of the quick-release cable drum stopper attached to the outer surface of the flange portion according to the present invention. Unlike Figures 4 and 5, the outer surface 520A of the flange portion 520 is further provided with a convex bump or projection 540, and the mounting portion 50 is a concave receiving portion 50C. The receiving portion 50C corresponds to the bump or projection 540, thereby attaching the quick-release cable drum stopper 1 to the outer surface 520A of the flange portion 520.

[0043] The explanation will be given with reference to Figure 7. Here, Figure 7 is an assembly diagram of a fourth embodiment of the quick-release cable drum stopper attached to the outer surface of the flange portion according to the present invention. A first magnetic element (magnetic element) 550 is further provided on the outer surface 520A of the flange portion 520, and a second magnetic element 50D is provided on the mounting portion 50. The first magnetic element 550 and the second magnetic element 50D attract each other, so that the quick-release cable drum stopper 1 can be attached to the outer surface 520A of the flange portion 520.

[0044] The first magnetic element 550 and the second magnetic element 50D may both be formed from a magnetic material, or one may be formed from a magnetic material and the other from a ferromagnetic or ferrimagnetic material attracted by the magnetic material.

[0045] The explanation will be given with reference to Figures 8 and 9. Here, Figure 8 is a perspective view of the quick-release cable drum stopper according to the present invention from another viewpoint. Figure 9 is a perspective view of the quick-release cable drum stopper according to the present invention from the bottom side.

[0046] As shown in Figures 8 and 9, the quick-release cable drum stopper 1 further includes a removal slot 55 and a plurality of anti-slip strips 35. The removal slot 55 is provided on the first surface 10A and extends to the flange contact portion 20, allowing the quick-release cable drum stopper 1 to be easily removed from the outer surface 520A of the flange portion 520. The anti-slip strips 35 are provided on the anti-slip portion 30 to further improve the frictional force.

[0047] Next, we will explain with reference to Figure 10. Here, Figure 10 is a partially enlarged view of the quick-release cable drum stopper according to the present invention in a state where it is in contact with the ground and the flange portion. As shown in Figure 10, the relationship between the shape of the quick-release cable drum stopper 1 and the ratio to the flange portion 520 can be explained in more detail by the relationship between the contact angle and the ratio.

[0048] In some embodiments, when the quick-release cable drum stopper 1 comes into contact with the ground G and a portion of the outer edge 523 of the flange 520, the point where the outer edge 523 of the flange 520 is located on the ground G becomes the first contact point P1, and the uppermost point where the outer edge 523 of the flange 520 comes into contact with the flange contact portion 20 becomes the second contact point P2.

[0049] Next, the first angle θ1 between the secant line D extending from the first contact point P1 to the second contact point P2 and the ground G is 27 to 34 degrees, preferably 29 to 32 degrees, for example, 31 degrees.

[0050] Furthermore, in some embodiments, the ratio (H / R1) of the vertical height H between the ground G and the second contact point P2 to the radius R1 of the cable drum flange is 0.48 to 0.54, for example, 0.52.

[0051] The second contact point P2 extends along the flange contact portion 20 to the ground G and is defined as having an extension radius R2. The ratio of the extension radius R2 to the radius R1 of the cable drum flange (R2 / R1) is between 0.38 and 0.44, for example, 0.42.

[0052] Figure 11 is a partially enlarged view of the quick-release cable drum stopper mounted on the outer surface of the flange portion according to the present invention.

[0053] As shown in Figure 11, when the quick-release cable drum stopper 1 is mounted on the outer surface 520A of the flange portion 520, the second angle θ2 between the first axis L1 extending from the center C of the cable drum flange portion to the edge of the flange contact portion 20 and the second axis L2 extending from the center C of the cable drum flange portion to the edge of the anti-slip portion 30 is 35 to 45 degrees, for example, 31 degrees.

[0054] Furthermore, since the quick-release cable drum stopper 1 and the cable drum flange 500 are manufactured from recyclable plastic, they can be reused, contributing to carbon reduction.

[0055] As described above, the quick-release cable drum stopper 1 can be selectively mounted on the outer surface 520A of the flange 520 of the cable drum flange 500, or selectively mounted on the outer peripheral edge 523 of the flange 520 and the part that contacts the ground G. Furthermore, it can be carried at any time to prevent loss, and by confirming that it is actually contacting and blocking during each operation, it is possible to prevent the cable drum flange 500 from slipping or being damaged.
