The scheme that the utility model solution technical problem is used is, a kind of elastic rotation cross-arm, including be vertically fixed on
The cement pole on ground, described cement pole is fixed hinged with the medial extremity of cross-arm in the horizontal direction, the outboard end of described cross-arm and bullet
Spring steel disc lower end is fixing to be connected, and described spring steel plate upper end is fixing with cement pole to be connected.
Further, above-mentioned cross-arm medial extremity is welded with connector, and described cross-arm edge is respectively equipped with away from cement pole direction
First fixed plate, the second fixed plate and support insulator.
Further, above-mentioned cement pole is socketed with the first anchor ear, the second anchor ear, described first anchor ear and spring steel plate upper end
Fixing connection, described spring steel plate lower end is fixing with the first fixed plate to be connected, and described second anchor ear outer end and connector are used fixing
Bolt is fixed hinged in the horizontal direction.
Further, above-mentioned cement pole is provided with drift bolt bolt, and described drift bolt bolt is fixing with oblique suspension rod upper end to be connected, institute
Stating oblique downrod lower end and the fixing connection of the second fixed plate, described oblique suspension rod is with regulation bolt.
Further, the opposing breakdown strength of the opposing breakdown strength of above-mentioned fixing bolt and cross-arm and connector weld
Opposing bending strength more than spring steel plate.
Further, above-mentioned cement pole top is fixedly connected with support insulator.
Compared with prior art, the utility model is when there is broken string in electric distribution network overhead wire, and cross-arm both sides produce injustice
Weighing apparatus tension force, spring steel plate bends, and cross-arm rotates around cement pole, thus reduces the torsion that cement pole is subject to, when unbalanced tensile force disappears
After mistake, cross-arm returns to origin-location under the effect of spring steel plate, and this cross-arm can reduce operation expense, and minimizing accident is made
The power off time becoming.

Detailed description of the invention
With detailed description of the invention, the utility model is further illustrated below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of elastic rotation cross-arm, including be vertically fixed on the cement pole 1 on ground, described cement pole 1
Fixing hinged in the horizontal direction with the medial extremity of cross-arm 12, the outboard end of described cross-arm 12 is fixing with spring steel plate 7 lower end to be connected,
Described spring steel plate 7 upper end is fixing with cement pole 1 to be connected.
Further, in order to reasonable in design, above-mentioned cross-arm 12 medial extremity is welded with connector 11, described cross-arm 12 along away from
Cement pole 1 direction is respectively equipped with the first fixed plate the 8th, the second fixed plate 13 and support insulator 2.
In order to reasonable in design, cross-arm 12 and connector 11 are L90x7 angle steel, and the second fixed plate 13 side is fixed with reinforcement
Plate 14.
Further, in order to reasonable in design, above-mentioned cement pole 1 is socketed with the first anchor ear the 3rd, the second anchor ear 9, described first armful
Hoop 3 is fixing with spring steel plate 7 upper end that thickness is 1.8 millimeters to be connected, described thickness be 1.8 millimeters spring steel plate 7 lower end and
First fixed plate 8 is fixing to be connected, and described second anchor ear 9 outer end and connector M12 fix bolt 10 and fix hinge in the horizontal direction
Connect.
Further, in order to reasonable in design, above-mentioned cement pole 1 is provided with drift bolt bolt 4, described drift bolt bolt 4 with tiltedly hang
Bar 6 upper end is fixing to be connected, and described oblique suspension rod 6 lower end is fixing with the second fixed plate 13 to be connected, and described oblique suspension rod 6 is with regulation bolt
5, oblique suspension rod 6 upper end can move left and right in the position of drift bolt bolt 4, and regulation bolt 5 is used for regulating between cement pole 1 and cross-arm 12
Tension force.
Further, in order to reasonable in design, the opposing breakdown strength of above-mentioned fixing bolt 10 and 12 cross-arms and connector 11
The opposing breakdown strength of weld resists bending strength more than spring steel plate 7, and cross-arm 12 rotates by torsion and around cement pole 1
When, this torsion preferentially makes spring steel plate 7 occur bending and deformation, and after torsion disappears, cross-arm 12 is in the elastic recovery of spring steel plate 7
