Abstract

The invention discloses a double-lever manual fire alarm button, comprising a box, a circuit board seat fixed in the box, a circuit board fixed on the circuit board seat, a trigger switch arranged on the circuit board and an operating panel capable of controlling the trigger switch to be turned off or on, wherein the box is composed of a base, side vertical plates and an upper cover with an opening; the operating panel is of a flat plate structure, the edge of the upper surface of the operating panel is plied-up to the edge of the opening of the upper cover, one end of the operating panel presses against and is connected with the side vertical plates via compression springs, the other end of the operating panel is separated from the side vertical plates, levers are arranged on two sides of the operating panel in the length direction, one end, close to the compression spring, of each lever is connected with the side vertical plate via a torsion spring, a lug extends out of each lever, the lugs are limited to the bottom of the operating panel, and the other end of each lug is limited to the top of the operating panel. The fire alarm button has the characteristics of dust prevention, fast alarm, high safety, high reliability and the like.

Description

technical field [0001] The invention relates to the technical field of fire alarm, in particular to a double-lever manual fire alarm button. Background technique [0002] The existing manual fire alarm button, no matter whether the operation panel is a translation type or a rotation type, will be separated from the front panel with a certain gap after the operation panel is pressed. After the operation panel is pressed, there will be dust, sundries and other foreign objects in this gap. entry, resulting in failure of internal mechanisms. [0003] Existing manual fire alarm buttons, especially in the structure of the rotary operation panel, the change of the operation panel before and after pressing is not obvious, even if a special mark is used to distinguish, because the displacement is small, it is difficult to distinguish the operation panel. down state. [0004] The existing manual alarm buttons are prone to false alarms and other phenomena in hot and humid environment...
