[0002] Ceiling grilles, a common type of ceiling component in interior decoration, are widely used in public places such as shopping malls, subway stations, airports, and office buildings. Existing ceiling grilles typically consist of hangers, joists, and grille strips. One end of the hanger is fixed to the ceiling wall, and the other end is connected to the horizontally arranged joists. The grille strips are then assembled to form a complete ceiling decorative surface. However, there are still many shortcomings in the installation and use of ceiling grilles in related technologies. For example, grille strips are often fixed by simple snap-fit ​​or screws, which can easily loosen due to vibration or long-term load, and there is a risk of local grille strips sagging or falling off. Some grille strips lack an effective positioning structure during assembly and rely solely on manual alignment, which can easily lead to uneven grille arrangement and affect the overall aesthetics.

[0022] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.

[0023] Please refer to Figures 1 to 4 The stable ceiling grid device of this application includes a hanger 1, a support rod 2, a fastener 3, and grid strips 4.

[0024] In the specific implementation process, multiple support rods 2 are connected between adjacent side walls 10, that is, the support rods 2 are arranged horizontally and fixed between adjacent side walls 10, and are used as load-bearing components of the grid strips 4. The two ends of the hanger 1 are connected to the top wall 20 and the support rod 2 respectively, so that the support rod 2 is reliably suspended below the top wall 20 to form an overall load-bearing frame. Several grid strips 4 are connected to the side of the support rod 2 away from the hanger 1 to form a continuous ceiling grid decorative surface. Furthermore, the fastener 3 includes a connecting seat 5, a first locking bolt 6, a second locking bolt 7, and a positioning post 8. The connecting seat 5 has a first mounting groove 51 protruding from the side facing the support rod 2. The first locking bolt 6 fixes the support rod 2 in the first mounting groove 51. The connecting seat 5 has a second mounting groove 52 on the side facing the grid strip 4. Part of the grid strip 4 is connected to the second mounting groove 52, and the second locking bolt 7 fixes the support rod 2 at the bottom of the second mounting groove 52, thereby preventing the grid strip 4 from loosening or falling off. The positioning post 8 is spaced apart from the first mounting groove 51 and connected to the side of the connecting seat 5 facing the support rod 2. The end of the positioning post 8 away from the connecting seat 5 extends into the support rod 2, forming a plug-in limiting and positioning structure for the support rod 2. Through the plug-in cooperation between the positioning post 8 and the support rod 2, not only is the alignment accuracy during installation improved, but the stability between the support rod 2 and the connecting seat 5 is also enhanced, avoiding the misalignment problem that is easy to occur in traditional bolt connections, and ensuring the consistency of ceiling grid assembly.

[0025] Therefore, the stable ceiling grid device in this embodiment achieves reliable suspension and stable installation of the grid strips 4 through the coordinated action of the hanger 1, support rod 2 and fastener 3, thereby improving the overall structural stability and installation efficiency.

[0026] In one example, the positioning posts 8 are symmetrically arranged on both sides of the connecting seat 5. Specifically, the connecting seat 5 has two parallel positioning posts 8 on the side facing the support rod 2. The two positioning posts 8 are located at the two side edges of the connecting seat 5, so that during installation, the positioning posts 8 can be inserted into the support rod 2 from both sides of the connecting seat 5 at the same time, so as to limit and stabilize the grid strip 4. This symmetrical arrangement can effectively avoid the problem of displacement or loosening caused by a single positioning post 8, so that the support rod 2 remains stable under stress, thereby improving the overall reliability and seismic performance of the ceiling grid device.

[0027] In one example, the positioning post 8 is integrally connected to the wall of the second mounting groove 52, that is, the positioning post 8 is formed by extending the wall of the second mounting groove 52 as a whole, thereby avoiding the need to open additional holes or install separately during processing and assembly.

[0028] The positioning post 8 has a rounded end away from the connecting seat 5, and the support rod 2 has a first alignment groove 21 corresponding to the positioning post 8. The rounded end of the positioning post 8 matches the first alignment groove 21, meaning that the rounded end of the positioning post 8 is designed to automatically guide it into the first alignment groove 21 during installation and fit against the groove wall. This design reduces frictional resistance when the positioning post 8 is inserted into the support rod 2, improving assembly efficiency. Furthermore, the matching of the rounded end with the first alignment groove 21 provides a stable limiting effect during use, preventing the support rod 2 from shifting or loosening relative to the connecting seat 5, thereby further enhancing the installation accuracy and overall stability of the ceiling grid device.

[0029] In one example, several grid strips 4 are arranged in a matrix on the side of the support rod 2 away from the hanger rod 1, thus forming an overall ceiling grid panel. Through this matrix arrangement, each grid strip 4 can be effectively supported by the support rod 2, while maintaining a preset spacing between adjacent grid strips, making the ceiling surface flat and beautiful, and evenly distributing the load when under stress, thereby improving the stability and load-bearing capacity of the entire ceiling grid device.

[0030] In the specific implementation process, the bottom of the second mounting groove 52 is provided with a second alignment groove 521, and the part of the grid strip 4 located in the second mounting groove 52 is provided with an alignment block 41. The alignment block 41 abuts against the second alignment groove 521. Specifically, the alignment block 41 can protrude along the width direction of the grid strip 4. When the grid strip 4 is partially inserted into the second mounting groove 52, the alignment block 41 abuts against the second alignment groove 521, thereby achieving precise positioning and anti-slip fixation of the grid strip 4. Through this structural design, when the grid strip 4 is subjected to force or vibration, the cooperation between the alignment block 41 and the second alignment groove 521 can effectively prevent the grid strip 4 from moving laterally or longitudinally, ensuring the overall stability and flatness of the ceiling grid device, and also facilitating the modular installation and disassembly maintenance of the grid strip 4.

[0031] Preferably, the cross-sectional profile of the alignment block 41 is arc-shaped, triangular, rectangular, or wedge-shaped.

[0032] It is understandable that the support rod 2 has a mounting groove 22 on the side near the fastener 3, which is used to support a batch of grid strips 4, that is, the first locking bolt 6 is connected to the first mounting groove 51 and the mounting groove 22 respectively.

[0033] In one example, a portion of the grille strip 4 is embedded in the second mounting groove 52 to ensure a secure connection between the two.

[0034] It should be noted that the support rod 2 and the grid strip 4 are both parallel to the top wall 20, and the hanger 1 is perpendicular to the support rod 2 and the top wall 20. Specifically, the support rod 2 is horizontally arranged between adjacent side walls 10, and the grid strip 4 is arranged in a direction parallel to the support rod 2 to form a continuous ceiling panel. The hanger 1 extends vertically downward from the top wall 20 and is connected to the support rod 2 to bear the weight of the entire support rod 2 and grid strip 4. Through this mutually perpendicular and parallel structural arrangement, the overall stable support of the ceiling grid device is achieved, keeping the ceiling surface flat. At the same time, the hanger 1 bears the main vertical load, ensuring that the device is not prone to sagging or tilting during use, thus improving the reliability and construction accuracy of the ceiling grid device.

[0035] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
