A fire alarm controller installation and fixing device

Abstract

This utility model discloses an installation and fixing device for a fire alarm controller, including a base plate with four mounting holes. A housing is fixedly connected to one side of the base plate, and a stop block is fixedly connected to the inner wall of the housing. The stop block has an inclined surface. A controller body is located on one side of the base plate, and a plug-in socket is fixedly connected to one side of the controller body. The plug-in socket has the same shape and size as the inside of the housing, and clearance grooves are provided on both sides of the plug-in socket. By setting a sliding plate and a stop block, pushing two crossbars on one side of the plug-in socket closer together causes the sliding plate to retract into the square through groove, allowing the plug-in socket to enter the housing. Releasing the crossbars causes the sliding plate to extend and be blocked by the stop block, thus fixing the controller body to the base plate. When disassembling the controller body, pushing the crossbars again causes the sliding plate to enter the square through groove, clearing the stop block, and the plug-in socket can be pulled out. No screws are needed for fixing and disassembling the controller body, making the operation convenient and time-saving.
