Claims

[Claims for Utility Model Registration] 1. A main body 10 consisting of a cylindrical body 20, an upper bottom wall 30 provided at the upper end of the cylindrical body 20, and a flange body 21 provided at the lower part of the outer wall of the cylindrical body 20; The fixing screw 51 is made up of an F-shaped portion 41 and a bent piece 42 formed by bending one end of the F-shaped portion 41 upward, and is inserted into the upper surface side of the upper bottom wall 30 of the main body 10 from below. The upper bottom wall 30 of the main body 10 has an opening 31 in the center for inserting a finger during attachment/detachment operation, and a plurality of fasteners 40 that are fixed by nuts 52 and can be raised or laid down. A plurality of screw insertion holes 32 are provided on the outside of the opening 31 through which the fixing screws 51 are inserted from the lower surface side, and a plurality of screw insertion holes 32 are provided on the upper surface between the opening 31 and the screw insertion holes 32 in correspondence with the screw insertion holes 32. A plurality of vertical walls 33 for locking the stopper are provided, and the stopper 40 is provided with a vertical slot 44 extending from the bent piece 42 to the F-shaped portion 41 and into which the fixing screw 51 is loosely inserted. A locking piece 45 is provided at the tip of the bent piece 42 to engage with the side edge 34 of the standing wall 33 and project above the opening 31 when the stopper 40 is raised. Mounting devices such as fire detectors. 2. Utility model registration claim No. 1, in which one of the vertical wall 33 on the upper surface of the upper bottom wall 30 of the main body 10 and the locking piece 45 of the stopper 40 has a convex shape, and the other has a concave shape that holds the convex shape. Mounting device for fire detectors etc. as described in paragraph 1.
