When tightening the mounting screws into the mounting holes mentioned above,
Since the base body rotates in the direction in which the screws and the mounting holes match, there is a drawback that it is difficult to install, and furthermore, if the mounting screws become loose after installation, they may come off through the insertion holes. For this reason, some screws have projections and depressions on the engagement surfaces of the screw heads on both sides of the penetrating groove, but since the size of the projections and depressions is constant, it is effective against further loosening. does not demonstrate.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing one embodiment of the instrument mounting device according to the present invention, and FIGS. 2 and 3 are cross-sectional views of a mounting hole provided in the instrument mounting device. The base body 1 is a main body of a sensor base on which a fire detector or the like is attached, and is screwed into mounting holes 3, 3 penetrating through an installation surface 2 such as a ceiling surface, through mounting screws 4, 4, and on the bottom surface of the base body 1, Conductor connection parts 6, 6 are provided for connecting conductor wires (not shown) that are connected to a power source or the like through a hole 5 provided in the center,
At the same time, the conductor connection parts 6, 6 also serve as a mounting bracket for attaching a main body (not shown) such as a fire detector.

面にしておくと基体１はがたつきにくい。 The width dimension a of the mounting holes 3, 3 is slightly larger than the outer diameter b of the heads of the mounting screws 4, 4, inner edges 7, 7 are provided inside the mounting holes 3, 3, and the groove between them is used for the mounting screws. A slope 9 or a continuous stepped portion 10 is formed on the lower surface through which the shaft portions 4, 4 penetrate and the screw heads of the inner edges 7, 7 are engaged. These slopes 9 or the consecutive steps 10 actually allow the mounting screws 4, 4 to move when the mounting screws 4, 4 are tightened to the lower surface of the inner edges 7, 7 through the insertion holes 8, 8. However, the mounting screws 4, 4 can be fed into the distal end 11 of the mounting holes 3, 3, which is the position opposite to the insertion holes 8, 8, where they are to be screwed. In addition, due to the slope 9 or the continuous step portion 10,
If the screwed mounting screws 4, 4 become loose, the base 1 will shake and the heads of the mounting screws 4, 4 will pass through the insertion holes 8, 8, and the base 1 will not fall. The heads of the screws 4, 4 are in the mounting holes 3,
It is possible to prevent the end portions 11, 11 from shifting toward the insertion holes 8, 8 from the screwing position of No. 3. It is even more effective if the lower surfaces of the step portions 10 that are successively provided here are sloped surfaces like the slope 9. Also, slope 9
Alternatively, if the distal end portions 11 of the step portions 10 that are successively arranged are made horizontal, the base body 1 is less likely to wobble.

In the sensor-based mounting device according to the present invention, when screwing onto an installation surface such as a ceiling surface, the mounting screw is formed by forming an inclined or continuous step on the inner edge locking surface of the mounting hole. When tightened to the lower surface of the inner edge through the insertion hole, the mounting screw can be fed into the position opposite to the insertion hole where it is to be screwed. In addition, to prevent the head of the mounting screw from passing through the insertion hole and causing the main body to wobble after installation, the head of the mounting screw must be placed in the direction of the insertion hole. can be prevented from moving to.
