Abstract

The invention provides a button structure of a manual fire alarm. When a person presses down a button, whether the manual fire alarm is on or not can be distinguished clearly, and the state of the button is instructed evidently. The button structure comprises a housing, a middle seat and a base. An operation panel area is arranged on the housing, an operation panel is located in the operation panel area and a mounting area formed by a middle plate, the middle plate is located inside the housing, the housing is covered on the base, and the middle seat is supported in a mounting fastener inside the housing. The button structure of the manual fire alarm is characterized in that an action button is arranged right below the operation panel and is supported in a spring seat of the middle seat through pressure springs, a convex fastener on the lower end face of a slider is ejected by one end of the action button, and an action spring is arranged on one side, close to the housing, of the slider.

Description

The press-button structure of hand fire alarm

Technical field

The present invention relates to the technical field of structures of hand fire alarm, be specially the press-button structure of hand fire alarm.

Background technology

The button of existing hand fire alarm, it is after fire-alarm button is pressed, and in the self structure of button, not significantly prompting, causes people cannot distinguish whether source is in alarm condition, and it does not have the state of obvious instruction button.

Summary of the invention

For the problems referred to above, the invention provides the press-button structure of hand fire alarm, after it presses the button people, can know and whether distinguish it in alarm condition, obviously the state of instruction button.

The press-button structure of hand fire alarm, its technical scheme is such: it comprises outer cover, middle seat, base, on described outer cover, be provided with guidance panel region, guidance panel is positioned at described guidance panel region, described guidance panel is arranged in the formed installation region of plate, described middle plate is positioned at the inner side of described outer cover, described outside housing cover is loaded on described base, described middle seat is supported in the installation buckle of described outer cover inside, it is characterized in that: under described guidance panel, be provided with Action Button, described Action Button is supported in the spring base of described middle seat by pressure spring, the evagination buckle of slide plate lower surface is withstood in one end of described Action Button, one side of the close described outer cover of described slide plate is provided with operating spring, the spacing direction of the direction of action of described operating spring and described evagination buckle is parallel, described guidance panel is specially the guidance panel of transparent material, close described operating spring one side of described slide plate is provided with warning region, the below of described slide plate is provided with printed board, described printed board buckle is connected in the upper surface of described middle seat, in described printed board, be provided with microswitch.

It is further characterized in that: in described printed board, be provided with brass fixed contact, described brass fixed contact runs through the corresponding mounting hole of described middle, and described base inner side is provided with bullet contact, described bullet contact corresponding to described brass fixed contact contact;

Described warning region is specially the region that is stained with yellow black alternate warning label, its under alarm condition not in invisible mode;

On the same circumference of the bottom of described outer cover, be evenly equipped with evagination buckle, on the circumference of corresponding described outer cover bottom, described base upper surface, be evenly equipped with buckle slot, described buckle slot is corresponding described evagination buckle one by one, spacing being loaded in described buckle slot after described evagination buckle rotation.

Adopt after the present invention,, under alarm condition, the evagination buckle of slide plate lower surface is not withstood in one end of Action Button, and slide plate position is fixed; Alarm condition, press the guidance panel of transparent material, guidance panel drives Action Button, depress pressure spring, one end of Action Button departs from the evagination buckle of slide plate lower surface, under the effect of operating spring, slide plate is pushed 10mm, slide plate triggers the microswitch (belonging to existing known technology) in printed board simultaneously, send alerting signal, the warning region of slide plate exposes to the guidance panel of transparent material simultaneously, after now people press the button, can whether clearly distinguish it in alarm condition, obviously the state of instruction button.
