Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a sensor embedding base mounting device for mounting a fire, gas leak, crime prevention, etc. sensor on a ceiling surface.

[Prior Art] As a sensor embedding base for easily attaching a sensor to a ceiling board, there are known examples such as Utility Model Publication No. 55-37993, Utility Model Application Publication No. 58-94089, or Utility Model Application No. 60-192094. It is being

These conventional embedded bases can be attached to a ceiling board by sandwiching the ceiling board between the flange provided on the sensor holding base and multiple holding fittings provided at the top of the base, and securing with screws. It was fixed.

[Problems to be Solved by the Invention] Such a conventional attachment mechanism to a ceiling plate is complicated and takes time to attach, and furthermore, the sensor may slip and rotate when inserted or removed. It had some disadvantages, such as:

[Means for solving the problem] This invention is a sensor embedded base consisting of a cylindrical base body having a wire passage hole in the center of the upper end and an outwardly protruding flange on the periphery of the lower end. The mounting device includes: a holding member provided to bridge the wire passage hole; a pair of presser metal fittings each having one end rotatably supported by the holding member and formed in a substantially dogleg shape; and the presser foot. It is equipped with a floater inserted into an insertion hole drilled in the support side of the metal fitting, and is sensed on the ceiling board by tightening the floater and the center part of the holding member with a single screw. This problem was solved by fixing the container embedding base.

[Embodiment] FIG. 1 is a cross-sectional view showing the mounting state of one embodiment of this invention, FIG. 2 is a bottom view of the same, FIG.
FIG. 2B shows an external view of the clamp and the holding member shown in FIG.

In FIG. 1, reference numeral 1 denotes a base body, which has a flange 11 and a sensor D is attached to its cylindrical portion. A wire hole 12 is provided at the center of the upper end of the base body 1, and wiring for connecting the sensor D to the outside is performed through the wire hole 12. Although the wire passage hole 12 is circular in this embodiment,
It may be a quadrilateral or a polygon, and is not particularly limited.

A holding member 3 is provided above the wire passage hole 12 to hold the pair of presser fittings 2, 2 in a state where the wire passage hole 12 is bridged. This holding member 3
can be made by molding it integrally with the base body 1, but it can be made separately as shown in Figure 3 (b).
When the holding member 3 is removably fixed to the base body 1 with screws or the like and is directly attached to an outlet box in the ceiling, for example, it is convenient to remove the holding member 3 from the base body 1 and attach it.

The holding member 3 rotatably holds one end portion of the presser metal fitting 2 as shown in FIG. 3A. That is, the protrusion 21 provided at one end of the presser metal fitting 2,
21 is inserted into the engagement hole 31 provided at the lower side of the tub-shaped holding member 3 and engaged. Furthermore, the presser metal fitting 2 has an uneven part for preventing slipping on the ceiling plate pressing part and an insertion hole 22 as shown in FIG. has been inserted.

Further, a single screw 5 is provided at the center of the holding member 3 and the swinger 4, so that the swinger 4 can be moved up and down with respect to the holding member 3. When the screw 5 is loosened, the swinger 4 moves upward, and the presser metal fitting 2 becomes vertically movable and can be flipped up to the state shown by the dotted line.

When installing such a base body 1 on the ceiling plate 6, first loosen the screws 5, and with the presser metal fitting 2 able to flip up freely, insert the presser metal fitting 2 into the ceiling plate 6 through a hole previously provided in the ceiling plate 6. Insert into the back,
The flange 11 of the base body 1 is pressed against the ceiling plate 6. Thereafter, by tightening the screws 5, the ceiling plate 6 is compressed by the flange 11 and the presser fitting 2 and fixed to the ceiling plate 6. Then the wiring hole 12
As shown in the bottom view in FIG.
It is attached by engaging with.

In this embodiment, only the presser fitting 2 is provided with an anti-slip pressing part, but if an uneven part is also provided on the ceiling plate 6 side of the flange 11, the anti-slip effect will be doubled. Furthermore, the base body 1 also serves as a socket for the sensor D;
It is also possible to install a new socket for the sensor D by screwing or the like.

[Effects of the invention] When the sensor embedded base mounting device of this invention is installed on the ceiling board, it can be easily and firmly fixed to the ceiling board by tightening a single screw, so it generally reduces the instability of the scaffolding. This has the effect of making it easier to work at high places and allowing safe and effective installation work.
Furthermore, it has the feature that it can be easily attached to an outlet box if necessary.
