Fire-fighting alternating current smoke detector capable of being installed easily

Abstract

The invention discloses a fire-fighting alternating current smoke detector capable of being installed easily. The detector comprises a pedestal and a joint portion cooperatively connected to the pedestal. The pedestal is formed by a shell portion, an empty slot and a joint block arranged in the empty slot. A top of the joint block and a central section of a top wall in the empty slot are fixedly connected. A top in the joint block is provided with a first sliding connection groove. Two sides of the joint block are provided with second sliding connection grooves which are extended up and down along the joint block. A first groove portion is arranged in the joint block of a bottom portion of the first sliding connection groove. A power connection hole is arranged in the shell portion of a top portion in the first sliding connection groove. Second groove portions are correspondingly arranged in the shell portion of two sides of the power connection hole. Guide rods which are extended downwardly are arranged in the second groove portions. Downward extension segments of the guide rods enter into the first sliding connection groove and are fixedly connected to a bottom wall in the first sliding connection groove. The guide rods are slidingly connected to telescoping blocks. Two sides of each telescoping block are penetrated into the second sliding connection grooves and are slidingly connected. An outer side of each guide rod on an upper end of each telescoping block is connected to a first elastic component in a wrapped connection mode. Chucking apparatuses are correspondingly arranged in the shell portion of left and right sides of a bottom portion in the empty slot.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to an easy-to-install 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 fixed together by screws and other fasteners. 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 is low,...

Problems solved by technology

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 fixed together by screws and other fasteners. 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. , low work efficiency, and at the same time, the conductive parts in the power supply seat are exposed to the outside world during maintenance. If people accidentally touch it, it is easy to induce electric shock accidents, and there is a great potential safety hazard
