Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically to an easy-to-disassemble keel structure for decorative ceilings. Background Technology

[0002] Current interior ceiling installations require a keel structure at the top of the building. Ceiling panels are fixed below the keel. The keel is generally divided into main keels and secondary keels. The main keel connects to the top of the building and provides support, while the secondary keel supports the ceiling panels. Connectors are installed between the main and secondary keels to fix the secondary keel to the main keel. However, existing connectors are generally fitted onto the main keel, making it difficult to remove the secondary keel or a specific connector from the main keel during later disassembly and maintenance. This often requires forcibly damaging the connector for maintenance or replacement, making later maintenance very inconvenient and time-consuming. Furthermore, existing connectors cannot fix the relative position of the secondary keel on the main keel; additional hangers are needed to fix the secondary keel, causing it to easily move relative to the main keel during installation, increasing installation difficulty and reducing worker efficiency during disassembly and assembly. Utility Model Content

The secondary fastening layer 9 is fixedly connected to the surface of block 8. The positioning rod 7 is passed through the waist hole opened on the surface of the secondary keel 5 and the fitting hole opened on the surface of the secondary fixing block 8 in sequence, thereby completing the fixed connection between the secondary keel 5 and the secondary fixing block 8, and thus realizing the fixed connection between the main keel 2 and the secondary keel 5. It can also enhance the stability of the relative position connection between the two, and facilitate the disassembly between the main keel 2 and the secondary keel 5, making it convenient for later maintenance and replacement. The decorative panel is fixedly connected to the lower surface of the secondary keel 5, thereby completing the ceiling decoration of the house.

At the same time, the limiting blocks are semi-cylindrical structures.

[0020] In this embodiment, as Figure 1 and Figure 2The end face of the secondary keel 5 has a U-shaped structure, and the setting of the limiting component 6 can help enhance the frictional resistance between the secondary keel 5 and the secondary fixing block 8, thereby reducing the probability of the secondary fixing block 8 accidentally sliding along the length of the secondary keel 5 in the inner cavity of the secondary keel 5, and helping to enhance the stability of the fixed connection between the main keel 2 and the secondary keel 5. At the same time, the end face of the limiting block has a hemispherical structure, which can reduce the difficulty of embedding the secondary fixing block 8.

At the same time, the dimensions of the positioning rod 7 and the fitting holes are compatible.

[0022] In this embodiment, as Figure 1 and Figure 2 The positioning rod 7, waist hole and fitting hole work together to further enhance the stability of the fixed connection between the secondary keel 5 and the secondary fixing block 8, and also help to enhance the convenience of disassembly and assembly, and reduce the difficulty of disassembly and assembly during later maintenance.

[0023] In a preferred embodiment, the secondary fixing block 8 has a convex shape, and the two sets of secondary fastening layers 9 fixedly connected to the protruding end of the secondary fixing block 8 have a rectangular structure. The width of the secondary fastening layer 9 is greater than the axial length of the limiting block, and the dimensions of the secondary fixing block 8 and the inner cavity of the secondary keel 5 are compatible.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The secondary fastening layer 9 can be made of soft rubber, which can help enhance the frictional resistance between the limiting component 6 and the secondary fastening layer 9 after they come into contact, thereby reducing the probability of relative sliding between the secondary fixing block 8 and the secondary keel 5.

[0025] As a preferred embodiment, the fixing plate 4 has a rectangular structure. The main fixing block 3 and the auxiliary fixing block 8, which are fixedly connected at both ends of the fixing plate 4, are distributed perpendicularly to each other.
