[0002] A shock-absorbing ceiling keel is a ceiling system specially used for interior decoration of buildings. Through carefully designed shock-absorbing structures and materials, it effectively reduces the impact of noise and vibration on the indoor environment. This system usually consists of shock-absorbing hanging parts, main keels, secondary keels and various accessories. The shock-absorbing hanging parts use their elastic materials to absorb vibration. The main keel serves as a supporting structure, and the secondary keel is used to fix the ceiling board. The whole system not only provides good noise reduction effect, but also has high flexibility and customization, and can adapt to different building structures and design requirements. The keel made of metal ensures the durability and stability of the system. At the same time, the ceiling surface is treated smoothly and beautifully, and can be integrated with various interior decoration styles. During installation, it is necessary to follow the design drawings and construction specifications to ensure the safety and functionality of the system, and regular maintenance and inspection are the key to ensuring its long-term stable operation.

[0003] In the prior art, if it is necessary to endow the ceiling keel with shock-absorbing function, shock-absorbing boxes or shock-absorbing hanging parts and other structures are often set on the connecting rod fixed to the ceiling. The addition of these structures will increase the installation complexity or cost of the ceiling keel to a certain extent.

[0004] Therefore, a shock-absorbing ceiling keel is proposed to solve or alleviate the above problems. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] A shock-absorbing ceiling keel, as Figure 1 and 3 shown, includes two lateral connecting plates 1, several middle connecting plates 2, several groups of telescopic members, several top plates 5, a connecting seat 3, and a connecting rod 4;

[0027] As Figure 2 shown, shock-absorbing pads 6 are fixedly connected to the bottom surfaces of the lateral connecting plate 1 and the middle connecting plate 2. The shock-absorbing pads 6 are in contact with the top plate 5. The shock-absorbing pads 6 have elastic deformation performance, and the shock-absorbing pads 6 are made of nitrile rubber.

[0028] As Figure 4 shown, a connecting hole 503 is provided on the side wall of the top plate 5. The top plate 5 includes an inserted plate part 501 located between the lateral connecting plate 1 and the middle connecting plate 2 and between adjacent middle connecting plates 2, and a baffle part 502 with a width greater than that of the inserted plate part 501. The top surface of the baffle part 502 is in contact with the shock-absorbing pad 6, and the connecting hole 503 is provided on the side wall of the inserted plate part 501. A ring of buffer rings 504 is fixedly connected in the connecting hole 503. The buffer rings 504 have elastic deformation performance, and the buffer rings 504 are made of nitrile rubber.

[0029] Several groups of telescopic members are respectively fixedly connected to the lower side walls of the lateral connecting plate 1 and the middle connecting plate 2. Concave holes are provided on the side walls of the lateral connecting plate 1 and the middle connecting plate 2. The telescopic members are fixedly connected in the concave holes. The groove depth of the concave holes is between the maximum length and the minimum length of the telescopic members. The telescopic members extend into the inner ring of the buffer ring 504, as Figure 5As shown in the figure, the telescopic member includes an outer tube 601, a middle tube 602 slidably connected inside the outer tube 601, an inner tube 603 slidably connected inside the middle tube 602, a conical portion 6031 fixedly connected to one end of the inner tube 603 away from the middle tube 602, and an elastic member 604 disposed inside the outer tube 601, the middle tube 602, and the inner tube 603. A hemispherical bump is fixedly connected to the outer peripheral walls of the inner tube 603 and the middle tube 602, and grooves for accommodating the bumps are formed on the inner peripheral walls of the middle tube 602 and the outer tube 601. The elastic member 604 is a spring.

[0030] The connecting seat 3 is fixedly connected to the side connecting plate 1, and the lower end of the connecting rod 4 is fixedly connected to the connecting seat 3.

[0031] When the present utility model is actually installed, the connecting rod 4 is fixed to the ceiling, and then the connecting seat 3 is fixed to the lower end of the connecting rod 4. The side connecting plate 1 and the middle connecting plate 2 are fixed through the connecting seat 3. Then, only by aligning the top plate 5 with the positions between the side connecting plate 1 and the middle connecting plate 2 and between adjacent middle connecting plates 2, and lifting the top plate 5 upward, the panel portion 501 of the top plate 5 can be made to abut against the inclined surface of the conical portion 6031 of the telescopic member, so that a component force in the length direction of the telescopic member is generated on the conical portion 6031, and then the elastic member 604 is compressed, causing the available lengths of the inner tube 603, the middle tube 602, and the outer tube 601 to be reduced and undergo collapse. Then, the telescopic member can be arranged corresponding to the position of the connecting hole 503, and the panel portion 501 can also be embedded between the side connecting plate 1 and the middle connecting plate 2 and between adjacent middle connecting plates 2. After the concave hole is aligned with the connecting hole 503, the telescopic member is no longer blocked, and the elastic member 604 releases elastic potential energy to make the telescopic member return to its original state, and then inserts into the connecting hole 503, and the installation can be completed. The installed ceiling keel can effectively buffer the rigid collision between the side connecting plate 1, the middle connecting plate 2, and the top plate 5 through the buffer ring 504 and the shock-absorbing pad 6. When vibration occurs, the vibration can also be weakened at the positions where the buffer ring 504 and the shock-absorbing pad 6 are located, thereby reducing the impact of the vibration on the entire ceiling keel.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
