Technical Field

[0001] The utility model belongs to the technical field of inspection openings, and in particular relates to an inspection opening installation node. Background Art

[0002] In the prior art, indoor ceilings generally include a frame and a top plate arranged above the frame. After the frame is set, if you want to remove it, you must first disassemble the frame, and then remove a row of top plates at the same time. It is impossible to disassemble and assemble a single top plate. When installing a central air conditioner indoors, when the air conditioner fails and needs to be repaired, it may be necessary to disassemble individual top plates on the roof, and then inspect the air conditioning pipes. The application of the existing top plate design will obviously bring a lot of trouble.

[0003] Therefore, the prior art discloses a utility model patent named an operating room inspection port (authorization announcement number: CN 202181712U), which is convenient for disassembly and assembly, and is convenient for the inspection of the air conditioner.

[0004] However, in the actual installation process, the size of the inspection opening needs to be larger than the size of the cover plate to ensure that the cover plate can be disassembled and assembled in the inspection opening.

The cover plate 3 is fixedly connected to the face frame 2, and the cover plate 3 is arranged in the maintenance opening. There is a gap 9 between the cover plate 3 and the face frame 2. The face frame 2 is provided with a connection part 1 6, and the connection part 1 6 is arranged in the maintenance opening. The cover plate 3 is provided with a connection part 2 7, and the connection part 2 7 is arranged in the maintenance opening. A sealing gasket 8 is provided between the connection part 1 6 and the connection part 2 7. The sealing gasket 8 seals the gap 9 to prevent dust inside the ceiling from entering the room through the gap 9, thereby ensuring the normal use of the operating room.

[0034] The utility model designs a fixing method for the cover plate 3 and the face frame 2, specifically: the cover plate 3 is provided with a mounting hole 17, and the mounting hole 17 is penetrated with 4 screws 10, and the screws 10 are arranged at the four corners of the cover plate 3, and the diameter of the screws 10 is 4 mm, and the specifications of the screws 10 are unified, so as to facilitate the unified installation of the screws 10. The screws 10 are connected between the second connection part 7 and the first connection part 6, and the screws 10 pass through the sealing gasket 8 and the angle steel 4. The diameter of the mounting hole 17 is larger than the diameter of the screw 10, and the cross-sectional area of the end 11 of the screw 10 is larger than the cross-sectional area of the mounting hole 17, so that the screws 10 can pass through the cover plate 3 conveniently, so that the screws 10 can be quickly connected between the second connection part 7 and the first connection part 6, and the screws 10 can be prevented from passing through the cover plate 3. The use of the screws 10 has a simple structure and low cost, and the connection between the cover plate 3 and the face frame 2 is firm and stable.

[0035] like Figures 6 to 9 As shown, it is the second embodiment of the utility model, which is used for auxiliary rooms.

[0036] A maintenance opening installation node includes a ceiling keel 1, a face frame 2, a cover plate 3 and an angle steel 4. Two ceiling keels 1 form a maintenance opening. The angle steel 4 is fixedly connected to the ceiling keel 1 through a fixing member 5. In the second embodiment, the fixing member 5 is a self-tapping screw. The face frame 2 and the angle steel 4 are fixedly connected. The cover plate 3 is fixedly connected to the face frame 2. The cover plate 3 is arranged in the maintenance opening. There is a gap 9 between the cover plate 3 and the face frame 2. The face frame 2 is provided with a connection part 1 6. The connection part 1 6 is arranged in the maintenance opening. The cover plate 3 is provided with a connection part 2 7. The connection part 2 7 is arranged in the maintenance opening.
