[0033] FIG. 1 shows a side view illustrating a hook-detachable protective tube for an arm tie according to an embodiment of the present invention, FIG. 2 shows a perspective view illustrating a hook-detachable protective tube for an arm tie according to an embodiment of the present invention, FIG. 3 shows a drawing illustrating a first fastening part and a second fastening part in a hook-detachable protective tube for an arm tie according to an embodiment of the present invention, and FIG. 4 shows a drawing in which a hook-detachable protective tube for an arm tie according to an embodiment of the present invention is applied.

[0034] Referring to FIGS. 1 to 4, a hook-detachable protective tube (1) for an arm tie according to one embodiment of the present invention is described as follows.

[0035] A hook-detachable protective tube (1) for an arm tie according to one embodiment of the present invention is configured to wrap around an arm tie (2) that supports a cross arm (3) attached to a pole (4).

[0036] The arm tie (2) is formed in the shape of a column in the shape of an 'ㄱ'. At this time, one side of the arm tie (2) comes into contact with the arm tie hook detachable protective tube (1) and is joined.

[0037] Specifically, the arm tie hook detachable protective tube (1) includes a first cover part (10), a second cover part (20), and a third cover part (30).

[0038] The first cover portion (10) can be joined by contacting one side of the arm tie (2). Specifically, the first cover portion (10) includes a first cover surface (11) and a first fastening portion (12).

[0039] The first cover surface (11) contacts one side of the arm tie (2) and has a larger surface area than the one side of the arm tie (2). For example, the first cover surface (11) may be formed in the shape of a rectangular flat plate. In this case, the width of the first cover surface (11) in the short axis direction may be larger than the width of the one side of the arm tie (2).

[0040] At this time, a first fastening part (12) is provided at one end of the short-axis direction of the first cover surface (11), and a second cover surface (20) may be disposed at the other end of the short-axis direction of the first cover surface (11).

[0041] The first fastening part (12) is detachably coupled to the third cover part (30). Specifically, the first fastening part (12) is detachably coupled to the second fastening part (32) of the third cover part (30).

[0042] The first fastening part (12) may include a hook receiving part (12a) that receives the hook part (32a) of the second fastening part (32). For example, the main body of the first fastening part (12) may be formed in a shape that is generally close to a cuboid, and the hook receiving part (12a) may be formed in the form of a groove or hole in the main body of the first fastening part (12).

[0043] At this time, the hook receiving portion (12a) may be formed to correspond to the shape of the hook portion (32a). For example, the hook receiving portion (12a) may be formed such that the gap on the entrance side into which the hook portion (32a) is inserted is narrower than the gap on the inner side into which the hook portion (32a) is received. With this configuration, the hook receiving portion (12a) and the hook portion (32a) can be hook-coupled. Therefore, once the hook portion (32a) is coupled to the hook receiving portion (12a), it has the effect of not being arbitrarily separated.

[0044] Meanwhile, the first fastening part (12) may further include a release lever (12b) that separates the hook part (32a) when pressed by a worker. Specifically, the release lever (12b) may be positioned at both ends of the main body of the first fastening part (12) and formed to be pressurizable by a worker. For example, the release lever (12b) may be formed to protrude in the shape of a square column from both ends of the main body of the first fastening part (12).

[0045] With this configuration, when the release lever (12b) is pressed by a worker's tool or the like, the main body of the first fastening part (12) can be opened. As a result, the entrance side of the hook receiving part (12a) opens, and the hook part (32a) can be separated.

[0046] In addition, the worker can easily connect the hook portion (32a) and the hook receiving portion (12a) and release the connection with a simple action of pressing the release lever (12b).

[0048] The second cover portion (20) can be arranged along a direction perpendicular to the first cover portion (10). Accordingly, the second cover portion (20) can cover a surface (other surface) arranged perpendicular to one side of the arm tie (2). At this time, the second cover portion (20) and the first cover portion (10) can be formed integrally, or they can be fixedly coupled to each other.

[0049] The second cover portion (20) includes a second cover surface (21) and a hinge portion (22).

[0050] The second cover surface (21) has a larger area than the surface (other surface) positioned perpendicular to one side of the arm tie (2). For example, the second cover surface (21) may be formed in the shape of a rectangular flat plate. In this case, the width of the second cover surface (21) in the short axis direction may be larger than the width of the arm tie (2). Accordingly, at least two sides of the 'L'-shaped arm tie (2) can be covered.

[0051] At this time, one end of the short-axis direction of the second cover surface (21) is connected to the other end of the short-axis direction of the first cover surface (11), and a hinge part (22) may be disposed at the other end of the short-axis direction.

[0052] The hinge portion (22) can hinge-connect the second cover surface (21) and the third cover surface (31) of the third cover portion (30). For example, the hinge portion (22) can form an axis along the long axis direction of the second cover surface (21) to rotate the third cover surface (31) relative to the second cover surface (21).

[0054] The third cover part (30) is hinge-connected to the second cover part (20) and detachably connected to the first cover part (10).

[0055] The third cover portion (30) includes a third cover surface (31) and a second fastening portion (32).

[0056] The third cover surface (31) can be combined with the first cover surface (11) and the second cover surface (21). Specifically, the third cover surface (31) can be combined with the second cover surface (21) through the hinge portion (22) and with the first cover surface (11) through the second fastening portion (32) and the first fastening portion (12).

[0057] The third cover surface (31) is formed to have a larger area than the first cover surface (11) and the second cover surface (21). For example, the third cover surface (31) may be formed in the shape of a rectangular flat plate. In this case, the length in the direction of the major axis of the third cover surface (31) may be equal to that of the first cover surface (11) and / or the second cover surface (21). On the other hand, the width in the direction of the minor axis of the third cover surface (31) may be formed to be larger than the width of the first cover surface (11) and / or the second cover surface (21).

[0058] Accordingly, when the first cover part (10) and the third cover part (30) are combined, the first cover part (10), the second cover part (20), and the third cover part (30) can be formed in the shape of a triangular prism overall and can be formed in a shape capable of accommodating an arm tie (2) inside.

[0059] With this configuration, the third cover surface (31) is combined with the first cover surface (11) and the second cover surface (21) to completely wrap the arm tie (2).

[0060] According to the hook-detachable protective tube (1) for an arm tie according to the present invention, it is composed of three cover surfaces that surround the arm tie (2), thereby having the effect of preventing contact between the arm tie (2) and the jumper wire.

[0061] Meanwhile, one end of the third cover surface (31) in the short direction is connected to the hinge part (22), and the other end in the short direction may have a second fastening part (32) arranged thereon.

[0062] The second fastening part (32) can be detachably coupled to the first fastening part (12).

[0063] Specifically, the second fastening part (32) may include a hook part (32a) and a ring (32b).

[0064] The hook portion (32a) is formed to protrude from the main body of the second fastening portion (32) toward the first cover portion (10) and can be inserted into the first fastening portion (12). For example, the hook portion (32a) can be formed to protrude in the shape of an arrow with a predetermined thickness from the main body of the second fastening portion (32), which is formed in the shape of a cuboid. Accordingly, the hook portion (32a) can be easily inserted into the first fastening portion (12), and after insertion, it is not arbitrarily separated unless the release lever (12b) is operated.

[0065] Meanwhile, the ring (32b) is provided on the main body of the second fastening part (32), but can be placed on the opposite side of the surface where the hook part (32a) is placed. The ring (32b) can be hooked onto a ring (not shown) provided on the worker's tool. With this configuration, when the connection between the first cover part (10) and the third cover part (30) is released, the arm tie hook detachable protective tube (1) can be prevented from falling.

[0067] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention and is not limited thereto. It is evident that modifications or improvements can be made by those skilled in the art within the technical scope of the present invention.

[0068] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims. Explanation of the symbols
