An AC smoke detector device

Abstract

The invention discloses an AC smoke detector device, which comprises a top seat, and a joint part in fit connection with the top seat, wherein an accommodating cavity is formed in the top seat; a guide rod is arranged in the accommodating cavity; the top end surface of the guide rod is fixedly connected with the inner top wall of the accommodating cavity; the front end surface of the guide rod is provided with a straight slot in a manner of extending up and down; a spiral rod is arranged in the straight slot; the top end of the spiral rod is connected with the motor; the spiral rod is in threaded fit connection with a steering block; the outer side of the guide rod is connected with a sliding block in a sliding manner; the steering block is fixedly connected with the sliding block; two sides of the sliding block are provided with first beveling blocks; a locking slot is correspondingly arranged in each sliding block at the inner side of each beveling block; a clamping rod which extends upwards is correspondingly arranged in each locking slot; a clamping block which penetrates into one corresponding locking slot is arranged in the top of the inner side of each clamping rod; an inserting slot which extends upwards and penetrates through the inner top wall of the sliding block is arranged in one side, far away from the corresponding locking slot, of each clamping rod; and an inserting rod is arranged at the inner top of the accommodating cavity corresponding to the inserting slots.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an AC smoke detector device. Background technique [0002] With the continuous improvement of people's awareness of fire protection, the use of AC smoke detectors is becoming more and more extensive. Currently, the installation of AC smoke detectors is generally fastened to the wall by bolts and connected to the wall. The external line connection realizes the power supply. However, the installation process through bolt fastening is cumbersome and takes a long time. When the AC smoke detector fails and needs to be repaired and maintained, it is not easy to disassemble. Exposed to the outside world, it is very easy to induce electric shock accidents, which threatens the safety during maintenance and has a large potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an AC smoke detector...
