Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and examples, and the modes of the present invention include but are not limited to the following examples.

[0025] like figure 1 As shown, the present invention provides a new type of manual alarm button, which includes an upper cover 1, an alarm push plate 4, a circuit board installation slot 11, a middle plate 14, an elastic mechanism and a buckle device.

[0026] The upper cover 1 is docked with the middle plate 14 to form the outer casing of the manual alarm button, and the upper cover 1 is respectively provided with a window 2 and a reset key port 3, such as: figure 2 shown. The alarm press plate 4 , the circuit board installation slot 11 , the elastic mechanism and the buckle device are all built in the space formed by the upper cover and the middle plate, and the alarm press plate 4 and the circuit board installation slot 11 are mutually buckled. At the same tim...

Abstract

The invention discloses a manual alarm button. The manual alarm button comprises an upper cover, an alarm pressing board, a circuit board mounting groove and a middle disc; a reset key opening is formed in the upper cover; the upper cover is in butt joint with the middle disc; the alarm pressing board and the circuit board mounting groove are both built in a space formed through the butt joint of the upper cover and the middle disc and are buckled to each other; a circuit board is built in the circuit board mounting groove; and the upper cover is provided with a window. The manual alarm button further comprises an elastic mechanism and a buckling device; a reset hole is formed in the alarm pressing board; the alarm pressing board contacts with the circuit board through an external force; the current position of the alarm pressing board is fixed through the elastic mechanism; the elastic mechanism can assist in realizing alarm operation; the buckling device is arranged at one side of the circuit board mounting groove and is used for clamping the alarm pressing board when the alarm pressing board contacts with the circuit board; and the elastic mechanism includes a limiting table, a rotary branch groove and an elastic rotation arm. The manual alarm button of the invention has the advantages of reasonable design, low cost and convenient use. With the manual alarm button adopted, the problems of complicated design, difficult assembly, high cost and easiness in malfunction in the prior art can be well solved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a manual alarm button. Background technique [0002] At present, in the fire alarm system, manual alarm is the most direct way to alarm, so whether the manual alarm operates smoothly and whether the design is reasonable becomes the key to whether the manual alarm button can work normally. In the existing manual alarm button, when the alarm is pressed, the internal alarm button board needs to make functional contact with the circuit board by combining the elastic function of the spring, so as to realize the alarm. In order to ensure the normal reset of the alarm button, most manufacturers choose to use the spring's expansion and contraction characteristics at the button point of the button, and use a specific reset key to reset it. Therefore, in the entire work and reset process of the manual alarm button, at least the cooperation of two springs is required to realize com...
