Abstract

The invention provides a rotation cooperation device and an alarm, and relates to the technical field of safety alarm. The rotation cooperation device comprises a hanging board and a main housing body. The main housing body is internally provided with arc first bosses; and the hanging board is provided with first groove ribs and cooperation ribs. The first groove ribs and the cooperation ribs are arranged concentrically and are matched with the first bosses. The alarm comprises a conductive device and the rotation cooperation device. The conductive device comprises mutually-matched metal spring members and metal clamps, wherein the metal spring members are fixedly arranged in the hanging board, and the metal clamps are fixedly arranged in the main housing body; and when the first bosses are matched with and abutted against the cooperation ribs, the metal spring members and the metal clamps are not contacted. When the main housing body and the hanging board are assembled cooperatively, the first bosses of the main housing body are abutted against the cooperation ribs of the hanging board to form a cavity, and the metal spring members and the metal clamps are arranged in the cavity and are not contacted, thereby reducing or even avoiding the cases of electrical circuit damage due to mis-conduction between the metal clamps and the metal spring members in the assembly process.

Description

technical field [0001] The invention relates to the technical field of security alarms, in particular to a rotating fitting device and an alarm. Background technique [0002] Ceiling-type gas alarms are mainly used in factories, homes or office buildings to detect the concentration of combustible gas, smoke, CO and other gases in the environment; ceiling-mounted gas alarms generally include a hanging board and a main shell Working components such as detectors, sound alarms, alarm indicators, relays and driving fans are installed in the body, peripheral lines are connected to the hanging board, and multiple matching wires are arranged on the hanging board and the main shell for connecting Metal shrapnel for each working element circuit. When in use, first fix the hanging board on the suspended ceiling of the house, then screw the main shell into the hanging board, and the metal shrapnel on the main housing and the metal shrapnel on the hanging board are matched and electrica...
