Problems solved by technology
[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 poses a threat to the safety of inspection and maintenance, and there is a large potential safety hazard

The invention discloses a ceiling smoke detector device which comprises a top seat and a joint part in matched connection with the top seat. An accommodation cavity is arranged in the top seat. A guide rod is arranged in the accommodation cavity. The top end face of the guide rod is fixedly connected with the inner top wall of the accommodation cavity. A through groove vertically extends on the front end face of the guide rod. A screw-shaped rod is arranged in the through groove. The top end of the screw-shaped rod is connected with a motor. A heat removing member is arranged on the casing of the motor. The heat removing member comprises a heat removing fin which is fixedly connected with the casing of the motor and a chill fan arranged on the heat removing fin. The screw-shaped rod is in threaded matched connection with a steering block. The outer side of the guide rod is slidably connected with a sliding block. The steering block is fixedly connected with the sliding block. First slanting blocks are arranged on both sides of the sliding block respectively. Locking grooves are correspondingly arranged in the sliding block on the inner side of each first slanting block. A clamping rod which extends upward is correspondingly arranged in each locking grove. A clamping block which runs into a locking groove is arranged at the top of the inner side of each clamping rod.
Description
technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a ceiling 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 a ceiling smoke ...
