Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an emergency alarm device used in communication equipment and the like.

[Conventional technology]

Conventionally, this type of emergency alarm device has a push button switch, a cracker plate having a disc-shaped cutout, and a cylindrical guide having an inner diameter slightly larger than the outer diameter of the cutout of the cutout. It was composed of.

[Problem that the invention attempts to solve]

In the above-mentioned conventional emergency alarm device, when an emergency alarm is activated, the punched part of the cracker plate is punched out and dropped into the cylindrical guide, and then the punched part of the cracker plate is removed. However, there is a drawback that it is difficult to maintain the emergency alarm pushbutton switch and causes loss of time during maintenance to restore the original state of the push button switch.

[Means for solving problems]

The emergency alarm device of the present invention includes a cylindrical guide having an opening at the top, a through hole at approximately the center of the bottom, and a groove at the bottom where the bottom joins the inner surface of the side wall. A push button switch is installed so that the push button is exposed inside the guide through the through hole, and has a punched out portion held at approximately the center to the extent that it can be punched out with finger pressure; The external shape of the punched part is smaller than the horizontal cross section of the guide so that the punched part can fall smoothly down the cylindrical inner surface of the guide when the punched part is punched out. and a cracker plate attached to the upper surface of the guide such that at least a part of the outer edge of the cutout is above the groove.

[Effect]

Therefore, when restoring the pushbutton switch to its original state after the punched out part of the cracker plate is punched out in an emergency and the pushbutton switch is operated, part of the outer edge of the punched out part must be dropped into the groove of the guide. For example, since the outer edge on the opposite side is lifted, the punched portion can be easily removed.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the emergency alarm device of the present invention, and FIG. 2 is a cross-sectional view taken along line XX in FIG. 1 in the direction of the arrow.

The guide 10 has a cylindrical shape and has an opening at the top. Further, a through hole 14 is formed in the center of the bottom surface of the guide 10, a U-shaped groove 12 is formed along the joint between the bottom surface and the side wall, and the other part of the bottom surface is formed with a flat guide bottom surface 11. It is becoming. The pushbutton switch 30 is attached so that a pushbutton 31 attached to the operating shaft of the pushbutton switch 30 passes through the through hole 14 and is exposed inside the guide 10. Kratzka plate 20
A disc-shaped punched out portion 21 having a diameter slightly smaller than the diameter of the bottom surface of the guide 10 is formed in the center thereof. The cracker plate 20 is attached to the communication device 40 so that the center of the punched portion 21 is on the central axis of the guide 10.

Therefore, when operating the emergency alarm device, punch out the punched out part 21 of the cracker plate 20,
Along the inner surface of the side wall of the guide 10, drop down to the guide bottom surface 11 shown by the solid line 23, and press the push button 31.
Press to operate the pushbutton switch 30 that generates an emergency signal. Next, a case where the original state is restored will be explained. Since the outer edge of the punched portion 21 that has been dropped to the point indicated by the solid line 23 is on the U-shaped groove 12, a part of the outer periphery of the guide bottom surface 11 is connected to the fulcrum 13.
If the outer edge of the punched out part 21 is pushed down as shown by arrow A and dropped into the U-shaped groove 12, the punched out part 21 will be in the state shown by the broken line 22, and the punched out part 21 can be easily removed. After removing the punched portion 21, the push button 31 is operated to return the push button switch 30 to its original state.

[Effect of idea]

As explained above, in the present invention, when the punched part of the Kratzka plate is punched out and dropped onto the bottom of the guide, a groove is formed in the part of the bottom of the guide where the outer edge of the punched part is located. This has the effect that it is possible to take out the punched out part that has fallen into the bottom of the guide and restore the push button switch for generating the emergency signal to its original state in a short amount of time.

Claims (1)

[Claims for Utility Model Registration] A cylindrical guide having an opening at the top, a through hole at approximately the center of the bottom, and a groove at the bottom where the bottom joins the inner surface of the side wall; The pushbutton switch is installed so that the pushbutton is exposed inside the guide through the through hole, and the pushbutton has a cutout in the center that is held to the extent that it can be pushed out with finger pressure. The outer shape is smaller than the horizontal cross section of the guide so that when the punched part is punched out, the punched part can fall smoothly down the cylindrical inner surface of the guide, and when the punched part reaches the bottom surface, the punched part and a cracker plate mounted on the upper surface of the guide so that at least a part of the outer edge of the plate is above the groove.
