The present invention relates to a light weight bracket for a telephone pole.

An electric cable is passed through the electric pole, and a wire post insulator or an insulator insulator in the form of a suspension insulator is fixed to the electric wire 100 fixed to the electric pole.

On the other hand, in order to fix the insulating insulator to the shimwang gold, the shimwang gold bracket is fixed and the above-mentioned insulator is fixed to the shimwang gold brick kit. No problems were found.

In other words, the insulated insulator fastened to the shinkansen fixes the electric wire. If the wind blows excessively, the electric wire is shaken and eventually the impact is transmitted to the shinkwan brick kit, so that the shinkwan brick kit is displaced from the shinkansen , And in some cases, an accident occurs in which the light alloy bracket is pulled out of the light alloy.

Even if an unexpected external force is applied to the telephone pole or vibration is applied, the Kwangkang Gold Bracket may be slightly displaced, resulting in the above-described accident.

In addition, the conventional light-weight brassiere bracket shown in FIG. 4 has a disadvantage that the position of the auxiliary iron piece 14 must be moved up and down with respect to the connecting surface 10 every time the size of the light guide metal is changed.

[TECHNICAL FIELD OF THE INVENTION]

As a background of the present invention, first of all, according to the Utility Model Registration No. 20-0269478, a bolt (not shown) for fixing the terminal of the insulator is fixed to the downward bent end 11 of the connecting surface 10, 12 and a nut 13 are assembled and an auxiliary iron piece 14 is assembled on the connecting surface 10 and a bolt for fixing the connecting surface 10 and the auxiliary iron piece 14 to the light- (15) and a nut (not shown).

As described above, the light-bridging bracket is the most widely used type. However, there is a disadvantage in that the bracket can not be maintained in a state of being fixed to the light guide bracket as described above. In the vertical portion and the horizontal portion of the connection surface 10, A plurality of grooves 10a and a plurality of holes 10b are formed in order to allow the positions of the bolts 15 and the bolts 15 to be changed in accordance with the size of the lightweight armature and the bolts 15 4 is a sphere having a size of 70 mm in width, 70 mm in length, 80 mm in width, 80 mm in length, 90 mm in width and 90 mm in width , 90 mm width, and 80 mm length and 80 mm width. In recent years, however, since the size of Shiwang Gold is mainly 70 mm by 70 mm, 80 mm by 80 mm and 80 mm by 80 mm, the above-mentioned spherical light-weight brackets have disadvantages of lacking practicality and economical efficiency.

[0008] Next, in Japanese Unexamined Patent Application Publication No. 10-2007-0006972, a "⊃" -shaped connecting member for fixing an insulator is fixed to a light-weighted joint with a bolt and a nut. And circular holes are formed. This is not only insufficient in durability due to poor structural strength of the connecting member but also is insecure because the connecting member moves to the left and right.

Next, referring to Patent Registration No. 10-0745385, the structure of the light metal is different from that of a conventional one, and two pairs of fixtures are fixed by bolts and nuts in order to fix the insulator on the different light metal pieces. So that assembly and replacement work is inconvenient and the manufacturing cost is increased, which is not adopted in the field.

In the case of the disclosure of Japanese Laid-Open Patent Publication No. 10-2006-0113100, the same connecting member as that used in the above-mentioned Laid-open Publication No. 10-2007-0006972 is used, So that a hole for inserting a fixture for gripping the left and right of the chain is formed.

That is, the above-described prior arts are different in structure and function from the light-weight brackets of the present invention.

2) Published Patent Publication No. 10-2007-0006972

3) Patent Registration No. 10-0745385

4) Published Patent Publication No. 10-2006-0113100

Accordingly, the present invention provides a new type of light guide bracket having a novel structure suitable for use in two most commonly used light guide brackets, Providing a kit is a challenge.

The present invention for solving the above-mentioned problems is constituted as follows.

A support base 1 perpendicular to the horizontal extending end 1a,

A clamping plate 3 fitted to the support base 1,

A fixing bolt 6 fitted to the extension plate 1a and the tightening plate 3 and a nut 5 assembled to the fixing bolt 6,

A protrusion 4 inserted into the circular hole 101 of the light guide 100 is provided at the center of the upper end of the extended end 1a and a core inserting tube 2 is fixed to the bottom surface of the insulator 200, And a first hole 1c and a second hole 1d through which the fixing bolt 6 passes are formed at the opposite end of the support base 1,

A fastening plate 3 fixing groove 1b is formed above the support base 1,

A minimum of four protrusions 3a are provided on the upper side of the fastening plate 3 and a first hole 3b and a second hole 3c are formed on the left side of the protrusion 3a through which the fixing bolt 6 passes A rectangular hole 3d is formed on the opposite side of the first hole 3b and the second hole 3c to be engaged with the fastening plate fixing groove 1b of the support plate 1. A rectangular hole 3d is formed in the rectangular hole 3d, 3) is formed in a slot (3e) through which the support (1) can pass when the support (1) is coupled to the support (1).

3 and 6, since the protrusion 4 formed on the extended end 1a is inserted into the hole 101 of the light arm 100, when the wire 100 is fixed to the wire 100, Even if external force is continuously applied to the wire or the poles and the light poles, the protrusion (4) does not fall out from the hole (101) of the light poles and maintains the position.

2, the insulation insulator 200 is fixed to the extension insulator 200 in a downwardly suspended insulator type as shown in FIG. 2. The insulation insulator 200 The wire fixing bracket 201 is fixed. In the present invention, the insulator 200 may be replaced with a line post insulator by rotating the present invention 180 degrees so that the core insulator 2 is positioned at an upper position in the state of FIG. 2. In this case, It is a reasonable sense to be.

As shown in FIGS. 7, 8, 9, and 10, at least four protrusions 3a are spaced apart from the fastening plate 3 of the present invention, and a fixing bolt 6 is provided on the left side of the protrusion 3a. The first hole 3b and the second hole 3c are formed through the first hole 3b and the second hole 3c on the opposite sides of the first hole 3b and the second hole 3c, And a rectangular hole 3d is formed in the square hole 3d and a slot 3e through which the support 1 can pass when the fastening plate 3 is coupled to the support 1 is formed in the rectangular hole 3d, The fixing bolts 6 are assembled to the support base 1 such that the projections 3a of the tightening plate 3 are directed upward and the fixing bolts 6 are fastened to the extending ends The first hole 1c of the fastening plate 1a and the first hole 3b of the tightening plate 3 are used and the present invention is fixed to a square lightening having a width of 70 mm and a width of 70 mm as shown in Fig. Fastening The fixing bolt 6 is assembled to the second hole 1d of the extending end 1a and the second hole 1d of the fastening plate 3 so that the projection 3a of the fastening plate 3 faces downward, 3c. In this case, the height of the projection 3a is 10 mm.

Therefore, the fastening plate fixing groove 1b is formed in only one place in the support base 1 of the present invention, and only the first hole 1c and the second hole 1d through which the fixing bolt 6 passes are formed, And only the first hole 3b and the second hole 3c through which the fixing bolts 6 pass are formed in the base 3 as well.

The present invention is characterized in that when the protrusion 4 formed on the extended end 1a is inserted into the circular hole 101 of the light guide 100 when the fixture is fixed to the light guide metal, There is an advantageous effect that it is possible to prevent the short circuit accident of the wire as well as the protection of the wire and the bracket because the fixed position is not released. There is a convenient and advantageous effect because it is possible to securely fasten the clamping plate to two kinds of clamps using projections without changing the position of the clamping plate up and down on the clamping base.
