Description

  The present invention relates to a rod-shaped antenna attachment device used when a rod-shaped antenna such as a coaxial antenna is attached to a support.

  To attach a coaxial rod-shaped antenna provided in a base station such as a cellular phone to a column, the opposite flange portions of the band piece wound around the rod-shaped antenna are opposed to each other with a column interposed therebetween. A pair of sandwiched pieces each provided with a flange piece at each of a pair of ends, and sandwiched between the flange pieces, and each of the overlapping flange pieces is fastened by a bolt and a nut screwed to the bolt. There is (for example, Patent Document 1).

  The conventional structure employs a configuration in which the band piece on the rod-shaped antenna side and the holding piece on the support column side are assembled with a bolt at the flange part piece, so that the bolt is loosened and the band piece (antenna) side is rotated around the bolt as a horizontal axis. The direction of the antenna may change from the time of setting, resulting in inconvenience.

  It is an object of the present invention to provide a device that can be easily attached to and supported by a pole with a simple structure (with a small number of parts) without changing from the setting (attachment) time. It was created as

  A planar U-shaped mounting frame projecting on the peripheral side of the rod-shaped antenna, a support plate provided on the column, and a mounting bracket interposed between the mounting frame and the support plate, the mounting bracket is a metal plate It is composed of an upright plate bent and connected in an orthogonal direction, a horizontal plate, and a triangular inclined plate having an angle with respect to both plates on both sides of the connecting portion of both plates, Is provided with a support hole through which a mounting bolt is inserted so as to match the mounting hole provided in the central piece, and a shaft through which a shaft bolt is inserted in the horizontal plate so as to match the first through hole provided in the support plate. And a configuration in which an azimuth adjustment hole for inserting an adjustment bolt is provided so that an appropriate one is aligned with a second through hole provided in the support plate and arranged concentrically around the shaft hole. To do.

  According to the present invention, it is possible to easily attach the rod-shaped antenna to the support column by assembling the mounting frame provided on the rod-shaped antenna side and the support base provided on the support column side via the mounting bracket. In addition, the mounting bracket is a triangular plate formed by bending a metal plate and connecting it to each other at an angle with respect to each plate on both sides of the vertical plate and the horizontal plate and the connecting portions of the two plates. Since it is provided with an inclined plate, it has load resistance in spite of its simple structure, and therefore a stable mounting state of the rod-shaped antenna can be obtained. Then, the azimuth angle of the antenna can be freely set within a preset range, and the practical azimuth mounting apparatus can be provided without the azimuth angle being changed over time.
