THE SUPPORTING BAR STRUCTURE OF A TELEGRAPH POLE

摘要

An insulator supporting bar structure of a telegraph pole is provided to adjust a direction of a cross arm according to an installation direction of the telegraph pole by freely rotating the direction of the cross arm having an insulator. In an insulator supporting bar structure of a telegraph pole, a telegraph pole(1) is consecutively installed erectly at regular intervals toward a household. A fixed cap(10) has a plurality of rotary grooves(11) formed on an upper circumference. A plurality of coupling grooves(10) are formed on upper and lower parts of the plurality of the rotary grooves(11). The fixed cap(10) is fixed on an upper part of the telegraph pole(1) through a clamp(14) in a lower part. The clamp(14) of the lower part is connected to an upper part through a connecting bar(15). A rotary unit(20) has a protrusive coupling projection(22). The coupling projection(22) is rotatably coupled to the rotary grooves(11) on both sides of the fixed cap(10). A screw hole(21) is formed on a front surface of the rotary unit(20). A U-shaped fixing unit(30) fixes the rotary unit(20) by being coupled to a coupling hole(13) of the fixed cap(10) outside the front surface of the rotary unit(20) when the rotary unit(20) rotated on the circumference of the fixed cap(10) is located at a right position. A X-shaped cross arm(40) is coupled to the screw hole(21) formed in front of the rotary unit(20) by a bolt(42). An insulator(41) is installed on one side of the cross arm(40).
