Fire-fighting alternating current smoke detector device

Abstract

The invention discloses a fire-fighting alternating current smoke detector device which comprises a base and a joint part in matching connection with the base, wherein the base is composed of an outer shell part, a hollow slot and a joint block arranged in the hollow slot; the top of the joint block is fixedly connected with the middle part of a top wall in the hollow slot; a first sliding slot is formed at the top in the joint block; second sliding slots which extend up and down along the joint block are formed on the two sides of the joint block; a first slot part is arranged in the joint block at the bottom of the first sliding slot; an electric conducting hole is formed in the outer shell part at the top in the first sliding slot; second slot parts are correspondingly arranged in the outer shell part on the two sides of the electric conducting hole; downward extending guide rods are arranged in the second slot parts; the downward extending sections of the guide rods enter into the first sliding slot and are fixedly connected with the bottom wall in the first sliding slot; stretching blocks are in sliding connection with the guide rods; the two sides of the stretching blocks enter into and are in sliding connection with the second sliding slots; first elastic elements are wound on the outer sides of the guide rods at the upper ends of the stretching blocks; and blocking devices are correspondingly arranged in the outer shell part on left and right sides at the bottom in the hollow slot.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting AC smoke detector device. Background technique [0002] At present, with the continuous improvement of people's fire awareness, smoke detectors are used more and more widely. Smoke detectors will be installed in some electronic computer rooms, communication rooms, movie or TV projection rooms, etc. as long as there is a risk of electrical fire. Traditional smoke detectors are generally connected together by screws and other fasteners. Installation and use When the smoke detector needs to be repaired and maintained, it is necessary to use tools such as a screwdriver to install the power supply unit and the sensing part together; when the smoke detector fails, it is necessary to use tools such as a screwdriver to disassemble the power supply unit and the sensing part, resulting in a long time-consuming installation and maintenance. , work efficiency...
