AI Technical Summary
The installation and removal process of existing infrared alarms is cumbersome, especially the installation of expansion screws, which is laborious and difficult to remove.
The mounting base design, which adopts a positioning block and spring structure, uses the positioning block to be inserted into the positioning port for positioning. Combined with the friction and buffering effect of the rubber sheet and compression spring, it enables quick installation and disassembly.
It enables rapid installation and removal of the alarm, increases the safety and stability of the equipment, and improves installation efficiency.
