Sealing hole for emergency lights

■Overview of Cockroach Sealing Hole 1. It consists of a mounting frame and a lid, with the lid fitted with ceiling finishing material, and the mounting frame can be attached to the ceiling finishing material, serving as a cockroach sealing hole (round inspection opening). 2. A hole is made in the ceiling finishing material from indoors, and the cockroach sealing hole is fitted and installed into that hole. 3. Cockroach sealing holes are installed in the ceilings of kitchens, cooking areas, and food preparation areas. 4. By opening the lid of the cockroach sealing hole, hands or arms can be inserted through the hole into the ceiling space to place extermination supplies from indoors into the ceiling space or behind the lid (such as insecticides, rodenticides, various traps, and cockroach or rat bait). 5. For example, in kitchens or cooking areas, even if insecticides (fumigation) like Valsan are used indoors, cockroaches escape into the ceiling space or under the floor. Additionally, cockroaches and rats originally hide in the ceiling space or under the floor. 6. Cockroach sealing holes/cockroach floor holes are provided in the ceiling space and under the floor to install extermination supplies in those areas for pest control. 7. In this way, cockroaches and rats hiding in the ceiling space or under the floor, which can cause collective food poisoning, can be exterminated, allowing for safe cooking and dining.

■Overview of Gas Leak Detector Mounting Hardware 1. It consists of a mounting frame and a cover, with the ceiling finishing material fitted into the cover and a stand combined with the mounting frame for the gas leak detector. 2. The gas leak detector is mounted on the stand of the gas leak detector hardware. 3. A hole is drilled in the ceiling finishing material, and the gas leak detector hardware is inserted into that hole and attached to the ceiling finishing material. Additionally, a cable catcher or arm is inserted through the hole to run and connect the power and signal lines in the ceiling space. 4. The finishing material with a hole is fitted into the cover, completing the assembly by securing the cover into the mounting frame of the main body. 5. The cover can be opened, allowing for easy gas leak testing and inspection of the gas leak detector from inside the room. 6. For example, if a gas leak occurs in the ceiling space of a building, the gas leak detector in the ceiling space detects the leak and triggers a gas leak alarm. It also sends an alert signal. 7. In this way, gas leaks in the ceiling space of a building can be detected early, preventing potential fires associated with gas leaks.

■Overview of Firefighting Sealing Hole 1. It consists of a mounting frame and a cover, with the ceiling finishing material fitted into the cover, allowing the mounting frame to be attached to the ceiling finishing material. A sprinkler head is attached to the cover. 2. A hole is made in the ceiling, and the firefighting sealing hole is inserted into that hole and attached to the ceiling finishing material. Additionally, a cable catcher or arm can be inserted through the hole to facilitate piping and wiring in the ceiling space. 3. The finishing material with a hole is fitted into the cover, and the sprinkler head is attached to the cover. The cover is then fitted into the mounting frame of the main body, completing the installation. 4. The cover can be removed or rotated, allowing for free adjustment and replacement of the head's direction. 5. After the ceiling work is completed, piping and wiring in the ceiling space, as well as the installation of the head, can be done from inside the room, leading to reduced construction time, lower costs, and safer work conditions. 6. Confirmation and inspection of the connections in the ceiling space can be easily performed from inside the room, making maintenance tasks easier. 7. It does not involve exposed wiring, preserving the building's aesthetic without compromising the finish and appearance. 8. Thus, facilitating the piping and installation of the sprinkler system without hindering the building is an extremely innovative method for renovations, expansions, renewals, and new constructions.

The security sealing hole consists of a mounting frame and a cover, with the ceiling finishing material fitted into the cover. Security surveillance cameras and security sensors can be installed on this cover, and the mounting frame is attached to the ceiling finishing material. Wires can be easily routed through the ceiling space or wall space from the opening of the cover. In other words, by installing the security sealing hole in the ceiling and opening the cover, one can insert a cable catcher or arm through the hole in the cover to wire cables from the room into the ceiling space, connecting them to the security surveillance cameras or sensors mounted on the cover. For example, one can insert a cable catcher (which has a structure like a fishing rod) through one security sealing hole into the ceiling space, extend it, and then hook a wire onto the tip from the other security sealing hole. By pulling the cable catcher back, the wire is routed into the ceiling space. Additionally, the wiring is connected to the security surveillance cameras or sensors mounted on the cover. In this way, simplifying the wiring for security equipment installation and making it easier to install security surveillance cameras and sensors without interfering with the building is an extremely innovative method for conducting security operations.
