Description

  The present invention relates to a holding means fixing mechanism, and more particularly to a holding means fixing mechanism capable of fixing a holding means for holding a bus device to a wall.

  As a holding means fixing mechanism capable of fixing a holding means for holding a conventional bus device to a wall, for example, a holding means fixing mechanism described in Patent Document 1 is shown in a perspective view showing a holding means fixing mechanism in FIG. As described above, the base 11 and the holding means 12 that can be locked to the base 11 are formed. Two holding projections 121 are formed on the inner peripheral edge of the holding means 12 facing the base 11. By rotating the holding means 12 about the circular center of the base 11 on the outer peripheral edge of the base 11, each of the two locking projections 121 enters along the tangential direction and is detachably locked. Two locking recesses 111 that can be formed are formed.

  However, when the holding means 12 is rotated and locked to the base 11, if the rotating force by the user is too large, the locking protrusion 121 or the locking recess 111 may be damaged by an impact. Further, by repeatedly engaging and removing the holding means 12 with the base 11, the engaging projection 121 and the engaging recess 111 are worn by friction with each other, so that the tightness of the engagement is reduced. Then, there is a possibility that they cannot be locked to each other.

  In addition, since the base 11 of the holding means fixing mechanism is fixed to the wall with the screw 13, there is a drawback that it cannot be applied to a wall surface made of glass or porcelain tile.
