BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an electronic device case, and more particularly to a mounting structure for mounting an electronic device case on a mast.

[0002]

2. Description of the Related Art A parabolic reflector is mounted on the upper end of an antenna mast, and an electronic equipment case containing a mixer, distributor, amplifier and the like is mounted in the middle of the antenna mast and electrically connected to a television. I have. The attachment of this electronic device case to the antenna mast is shown in FIGS.
This is performed as shown in FIG.

That is, an electronic device case 10 made of synthetic resin
A rectangular frame 102 is integrally formed outwardly on the back of 1, and an elongated through hole 105 through which a tightening bolt 104 is inserted is formed in a vertical wall 103 of the rectangular frame 102. Tightening bolt 104
A U-shaped body formed of a rod member and having screw portions 107 extending in the same direction from both ends of the shaft portion 106, respectively.
7 is provided with a screw thread 108 on the tip side.
04 is inserted into the through-hole 105, and the screw 107
Is provided outside the vertical wall 103 so as to be rotatable about a shaft 106.

A screw portion 107 of the tightening bolt 104 is inserted into both ends of a pressing member 110 having a support recess 109 in the center inner surface, and a wing nut 111 is screwed into a screw thread 108. FIGS. 6 and 7 show a state in which the electronic device case 101 is mounted on the antenna mast when the electronic device case 101 is mounted on the antenna mast. The antenna mast is inserted between the pressing member 110 and the square frame 102, and the wing nut 111 is tightened and fixed.

By turning the tightening bolt 104, the screw 10
7 Keep the electronic device case in a horizontal position.
101 A stopper piece 112 is swelled outwardly inside the joint between the shaft portion 106 and the screw portion 107 on the rear surface, and the width L of the stopper piece 112 is determined by the inner size L 'of the screw portion 107 of the tightening bolt 104. It is set large. Also, this stopper piece
The holding piece 113 bulges above the stopper piece 112 so that the screw portion 107 is sandwiched between the stopper piece 112 and the holding piece 113.

[0006]

With the above-described mounting structure of the electronic device case, when the tightening bolt 104 is rotated, the width L of the stopper piece 112 is set to the width of the screw portion 10.
7 is larger than the inner dimension L '
Since the base end of 107 has to climb over the stopper piece 112, the rotation of the tightening bolt 104 is heavy and not smooth, and sometimes the stopper piece 112 and the screw part 107 are damaged.

[0007] Since the operation of attaching the electronic device case 101 to the antenna mast is performed by a worker at a high place and in a very unstable posture, the tightening bolt 104 is easily rotated and the screw portion 107 is rotated. Must be able to be held horizontally.

[0008]

SUMMARY OF THE INVENTION Therefore, in order to facilitate mounting of an electronic device case, the present invention provides a screw extending in the same direction from both ends of a rod-shaped shaft portion into a through hole on the back of the electronic device case. The shaft portion of a U-shaped tightening bolt having a portion is inserted, the screw portion is inserted into a pressing member having a support recess on the center inner surface, and a wing nut is screwed into a screw carved on the tip side of the screw portion. When attaching the electronic device case to the mast, rotate the tightening bolt and hold the horizontal screw portion with the elastic nail piece to join the shaft and screw portion of the tightening bolt on the back of the electronic device case inside and outside. The width of the elastic claw piece is set to be larger than the width of the screw part of the tightening bolt in the width direction, and the screw part is urged outward with the elastic claw piece to elastically deform the screw part. Provide a holding piece to be held between the claw piece and the upper part of the elastic claw piece, and tighten the tightening bolt. To move the screw part against the urging force that urges the elastic claw piece toward the outside, the screw part of the tightening bolt is positioned between the elastic claw piece and the holding piece, and the returned elasticity The mounting structure of the electronic device case is such that the screw portion is sandwiched between the elastic claw piece and the holding piece by the urging force for urging the claw piece upward.

[0009]

When the electronic device case is mounted on the mast, the stopper bolt that holds the horizontal screw portion by rotating the tightening bolt is attached to the inside and outside of the joint between the shaft portion and the screw portion of the tightening bolt on the back of the electronic device case. And the dimension of the stopper piece in the width direction is set to be larger than the dimension of the inner width direction of the screw portion of the tightening bolt, but since the stopper piece is formed of an elastic claw piece, When the screw part is rotated, the elastic claw piece is easily deformed and restored after the rotation, and supports the screw part.
