[Detailed description of the device]

[0001]

[Industrial applications]

 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]

[Prior art]

 A parabolic reflector is attached to the upper end of the antenna mast, and an electronic device case containing a mixer, a distributor, an amplifier, etc. is attached in the middle of the antenna mast and is electrically connected to the television. This electronic equipment case is attached to the antenna mast as shown in FIGS. 6 and 7.

That is, a rectangular frame 102 is integrally formed on the rear surface of an electronic device case 101 made of synthetic resin so as to face outward, and a vertical hole 103 has a long hole through which a tightening bolt 104 is inserted. A through hole 105 is formed. The tightening bolt 104 is a U-shaped body formed of a rod member and having a threaded portion 107 extending in the same direction from both ends of the shaft portion 106. A thread 108 is engraved on the tip side of the threaded portion 107. The shaft portion 106 of the tightening bolt 104 is inserted into the through hole 105, and the screw portion 107 is located outside the vertical wall 103 and is rotatable around the shaft portion 106.

The screw portion 107 of the tightening bolt 104 is inserted into both ends of a pressing member 110 having a support recess 109 on the inner surface of the center, and a wing nut 111 is screwed to the screw thread 108. The state of FIGS. 6 and 7 is the state of packing or mounting on a wall. To attach the electronic device case 101 to the antenna mast, the tightening bolt 104 is rotated to make the screw portion 107 horizontal. The antenna mast is inserted between the pressing member 110 and the square frame 102, and the wing nut 111 is tightened and fixed.

In order to maintain the posture in which the screw portion 107 is horizontal by rotating the tightening bolt 104, the shaft portion 106 on the rear surface of the electronic device case 101 and the screw portion 107 are joined to the inside and outside of the stopper. The piece 112 is swollen, and the dimension L of the stopper piece 112 in the width direction is set to be larger than the inner dimension L ′ of the threaded portion 107 of the tightening bolt 104. Further, a holding piece 113 is bulged above the stopper piece 112 in order to hold the screw portion 107 with the stopper piece 112.

[0006]

[Problems to be solved by the device]

 With the electronic equipment case mounting structure as described above, when the tightening bolt 104 is rotated, the width dimension L of the stopper piece 112 is set to be larger than the inner dimension L ′ of the screw portion 107. Therefore, since the base end of the screw portion 107 has to go over the stopper piece 112, the tightening bolt 104 does not rotate smoothly and smoothly, and sometimes the stopper piece 112 and the screw portion 107 are damaged. May occur.

When mounting the electronic device case 101 on the antenna mast, the worker performs the work in a very unstable posture even at a high place, so that the tightening bolt 104 is easily rotated, and the screw is attached. It is necessary that the part 107 can be held horizontally.

[0008]

[Means for Solving the Problems]

 Therefore, according to the present invention, in order to facilitate mounting of the electronic device case, a U-shaped tightening having a screw portion extending in the same direction from both ends of a rod-shaped shaft portion is provided in a through hole on the back surface of the electronic device case. Insert the shaft part of the bolt, insert the screw part into a pressing member that has a support recess on the center inner surface, screw the wing nut into the thread engraved on the tip side of the screw part, and attach the electronic device case to the mast. At this time, a stopper piece that rotates the tightening bolt to hold the horizontal screw part is provided inside and outside the joint between the shaft part of the tightening bolt and the screw part on the back of the electronic device case, and the stopper piece width direction. Is set larger than the dimension in the width direction of the screw part of the tightening bolt, and a stopper is provided on the top of the stopper piece to hold the screw part with the stopper piece. Form the piece with elastic claw pieces And the mounting structure of the electronic equipment case.

[0009]

[Action]

 When attaching the electronic device case to the mast, a stopper piece that rotates the tightening bolt to hold the horizontal screw part is provided inside and outside the joint between the shaft part of the tightening bolt and the screw part on the back of the electronic device case. The dimension of the stopper piece in the width direction is set to be larger than the dimension of the screw part of the tightening bolt in the inner width direction, but since the stopper piece is formed of elastic tabs, the screw part of the tightening bolt is At the time of rotation, the elastic claw pieces are easily deformed, and after rotation, they are restored to support the screw portion.
