持しうるように構成した活線作業用保護カバーが
提案されている。 Conventionally, electric wire protective covers were used, for example, in 1973.
-22397, the tube body is made of a double layer, the outer wall and the inner wall are connected by several ribs, and both have cracks at corresponding parts of the bottom of the outer wall and the inner wall, and the outer wall One of the legs that connects to the inner wall is straight, and the other leg has a fin-like piece at the root, and the lower end of the leg is bent at a right angle, and this bent part, the fin-like piece, and the inner surface of both legs A protective cover for live line work has been proposed which is configured to support linear legs.

から直接外部に逸脱しやすい欠点がある。 However, such a protective cover for live wire work has a crack at the corresponding bottom of the outer wall and the inner wall, and a leg is provided that connects the outer wall and the inner wall along this crack. Even if a fin-like piece is provided at the root of the leg, there is a drawback that when the leg is opened by an external force such as an impact, the electric wire is likely to deviate directly from the crack to the outside.

とにより、上述の欠点を解消した電線防護カバー
を提供するものである。 In view of these conventional drawbacks, the present invention has been developed by making the inner diameter of the inner cylinder smaller than the outer diameter of the electric wire, and by positioning the opening of the inner cylinder and the opening of the outer cylinder so that they do not face each other. The present invention provides a wire protection cover that eliminates the above-mentioned drawbacks by having a double cylindrical shape that is provided in a staggered manner.

る。 The outer cylinder 2 has an appropriate shape such as circular, oval, or polygonal in cross section, and its inner diameter is sized to maintain at least a space large enough to insert the electric wire 8 between it and the inner cylinder 1. Further, an opening 6 is provided along the length of the outer cylinder 2 at a portion corresponding to the predetermined ventilation chamber 4', and the opening 6 serves as an insertion port for the electric wire 8. The opening 6 is provided at a shifted position so as not to face the opening 5 of the inner cylinder 1. In particular, it is better to provide the openings 5 and 6 as far apart as possible as shown in FIGS. This is preferable because deviation can be more completely prevented. Further, legs 7, 7 are provided on the opening edge of the opening 6 to protrude outward from the outer cylinder 2 so as to face each other.

直接開口部から外部に逸脱することがない。 As detailed above, in the wire protection cover of the present invention, the inner diameter of the inner tube is larger than the outer diameter of the wire, and openings are opened in the inner tube and the outer tube, respectively, corresponding to the predetermined ventilation chambers between the inner tube and the outer tube. Since the openings are provided at different positions so that they do not face each other, the wires can be securely held within the inner cylinder, and even if the legs open due to external force such as impact, As shown in the figure, the electric wire does not directly escape from the opening to the outside.
