[0034] Embodiment 1

[0035] In this embodiment, the ceiling module is composed of detachably connected keels and gussets, and multiple ceiling modules are combined and connected into a ceiling device through locking members, and the ceiling device is stably connected to the ceiling through adjustable length suspension rods, and lighting lamps, air conditioners and fire relief holes are further installed in the ceiling device, realizing the unification of multiple functions, simplifying construction operations, reducing production costs, and improving production efficiency.

[0036] A ceiling device comprises: at least two connected ceiling modules 1; the ceiling module 1 comprises: a keel 2, a suspension rod 3 with adjustable length and a gusset plate 4 for sound absorption and noise reduction, one end of the suspension rod 3 is connected to the ceiling, the other end of the suspension rod 3 is detachably connected to the keel 2, and the gusset plate 4 is connected to the keel 2; the keels 2 and / or gusset plates 4 between adjacent ceiling modules 1 are connected; at least one gusset plate 4 is provided with a lamp trough 5 for installing a lighting lamp.

[0037] The present embodiment provides a ceiling device, which is intended to provide a flexible installation method, excellent sound absorption and noise reduction effects, and convenient lighting equipment installation options. The ceiling device is mainly composed of the following key parts: First, the device includes at least two ceiling modules 1. These ceiling modules 1 are closely connected through a specific connection method to ensure the stability and aesthetics of the entire ceiling structure. The core components of each ceiling module 1 include a keel 2, a length-adjustable suspension rod 3, and a gusset plate 4 with sound absorption and noise reduction functions. One end of the suspension rod 3 is connected to the ceiling, and the other end is detachably connected to the keel 2. This design makes the installation and disassembly of the ceiling module extremely convenient, and facilitates subsequent maintenance and replacement.

[0038] The gusset plate 4 has a powerful sound absorption and noise reduction function. The gusset plate 4 is closely connected to the keel 2 through a specific connection method to ensure the stability and sound absorption effect of the entire ceiling structure. In addition, in order to improve the tightness of the connection between the ceiling modules and the stability of the overall structure, the keel 2 and gusset plate 4 between adjacent ceiling modules 1 are also carefully connected, making the entire ceiling device more sturdy and durable.

[0039] Furthermore, the ceiling device also takes into account the installation requirements of lighting equipment. A lamp trough 5 for installing a lighting lamp is specially provided on at least one gusset plate 4. This design makes the installation of the lighting equipment extremely simple, and also provides sufficient lighting light for the entire space.

[0040] In a specific embodiment, it includes: a plurality of adjacent keels 2 are detachably connected as one body; or

[0041] A plurality of adjacent keels 2 are fixedly connected as a whole.

[0042] In this embodiment, the design of the ceiling device fully considers the connection mode and flexibility between the keels 2. When it is necessary to build a continuous, stable and rigid ceiling structure, multiple adjacent keels 2 can be detachably connected as a whole. This connection method usually uses standard connectors such as bolts, buckles or slots to ensure that the connection between the keels is both firm and easy to disassemble. Through the detachable connection, the ceiling module 1 can be easily installed, disassembled and reorganized to adapt to different space layouts and renovation requirements.

[0043] On the other hand, if the ceiling device requires higher stability and long-term fixation, it is possible to choose to fix multiple adjacent keels 2 together. In practical applications, the fixed connection usually uses welding, riveting or strong glue to ensure that the connection between the keels 2 is more firm and durable. This connection method is suitable for long-term unchanged ceiling structures, such as commercial spaces, exhibition halls or conference rooms.

[0044] In a specific embodiment, the side of the gusset plate 4 facing the keel 2 is provided with a gusset plate 4 extension; the side of the keel 2 facing the gusset plate 4 is provided with a keel 2 extension corresponding to the gusset plate 4 extension;

[0045] The connection between the pinch plate 4 and the keel 2 is achieved by locking the pinch plate 4 and the keel 2 together through the locking member 6 .

[0046] In this embodiment, in order to ensure the convenience of installation and the stability of the connection, the extension of the gusset plate 4 is cleverly set on the side of the gusset plate 4 facing the keel 2. This extension not only increases the contact area between the gusset plate 4 and the keel 2, but also provides an additional connection point, thereby enhancing the stability of the connection. At the same time, the extension of the keel 2 corresponding to the extension of the gusset plate 4 is set on the side of the keel 2 facing the gusset plate 4. The two extensions match in shape and size.

[0047] During the connection process, the present embodiment introduces a locking member 6, which fully considers the convenience of operation and the stability of the connection. By placing the locking member 6 between the extension of the gusset plate 4 and the extension of the keel 2, and then applying appropriate force, the locking member 6 can tightly buckle the gusset plate 4 and the keel 2 together. This process is simple and fast, without the need for complex tools or techniques, which greatly improves the efficiency and convenience of installation. Through the method of buckling and locking the extension of the gusset plate 4 with the extension of the keel 2, the connection between the gusset plate 4 and the keel 2 becomes very stable. Even under long-term use and the influence of the external environment, the connection will not easily loosen or deform. At the same time, this connection method also has good detachability. If the gusset plate needs to be replaced or repaired, the disassembly can be easily completed by loosening the locking member 6.

[0048] In a specific embodiment, the suspension rod 3 includes a top hanging weight 31, a first hanging weight 32, a first pull rod 33, an adjustment rod 34, a second pull rod 35, a second hanging weight 36 and a bottom connecting piece 37 connected in sequence, one end of the adjustment rod 34 is fully or partially sleeved on the first pull rod 33, and the other end is fully or partially sleeved on the second pull rod 35, and the adjustment rod 34 is used to adjust the length of the suspension rod 3;

[0049] The top of the suspension rod 3 is connected to the ceiling via a top hanging code 31 , and the bottom of the suspension rod 3 is connected to the keel 2 via a bottom connecting piece 37 .

[0050] In this embodiment, the suspension rod 3 includes a top hanging bracket 31, a first hanging bracket 32, a first pull rod 33, an adjustment rod 34, a second pull rod 35, a second hanging bracket 36 and a bottom connecting member 37. These components fully consider the flexibility and stability of the connection, so that the suspension rod 3 not only has a strong load-bearing capacity, but also can be adjusted in length according to actual needs.

[0051] The top hanging bracket 31 is the starting point of the hanger 3, and its design is sturdy and easy to install. Through the top hanging bracket 31, the hanger 3 can be firmly hung on the ceiling to ensure the stability of the entire ceiling system; the first hanging bracket 32 ​​is connected to the top hanging bracket 31, which plays a role of transition and support. It ensures the stable suspension of the hanger 3 on the ceiling and provides a connection point for the subsequent pull rod assembly. The first pull rod 33 is one of the main load-bearing parts of the hanger 3, one end of which is connected to the first hanging bracket 32, and the other end is connected to the adjustment rod 34. Through the first pull rod 33, the ceiling system can bear the weight from the keel 2 and the gusset plate 4; the adjustment rod 34 is a key component in the hanger 3, which is fully or partially mounted on the first pull rod 33 and the second pull rod 35. By adjusting the position of the adjustment rod 34, the user can easily adjust the height and level of the ceiling system to adapt to different installation environments and needs; the second pull rod 35 is another main load-bearing part of the hanger 3, and its design is similar to the first pull rod 33. One end of it is connected to the adjustment rod 34, and the other end is connected to the second hanging weight 36. The existence of the second tie rod 35 further enhances the load-bearing capacity and stability of the hanger 3; the second hanging weight 36, as the bottom transition component of the hanger 3, not only connects the second tie rod 35 and the bottom connecting piece 37, but also plays a role of buffering and supporting. Through the second hanging weight 36, the hanger 3 can evenly transfer the weight to the keel 2, reducing the stress concentration phenomenon of the ceiling system.

[0052] Finally, the bottom connector 37 is used as the connection point between the hanger rod 3 and the keel 2, and is tightly connected to the keel 2 through bolts, nuts or other fasteners to ensure that the connection between the hanger rod 3 and the keel 2 is firm and reliable. Through the bottom connector 37, the hanger rod 3 can effectively transfer the weight of the ceiling system to the keel 2, and then to the wall, ensuring the stability and safety of the entire ceiling system.

[0053] In a specific embodiment, one end of the adjusting rod 34 is threadedly connected to the first pull rod 33 ; and / or the other end of the adjusting rod 34 is threadedly connected to the second pull rod 35 .

[0054] In this embodiment, the adjustment rod 34 allows the user to flexibly adjust the length of the suspension rod 3 according to actual installation requirements. This adjustment function is mainly achieved through the connection between the adjustment rod 34 and the first pull rod 33 and the second pull rod 35, specifically, through a threaded connection. First, both ends of the adjustment rod 34 are designed with internal threads or external threads, which form a threaded connection with the corresponding parts of the first pull rod 33 and the second pull rod 35 respectively. This connection method ensures the firmness and stability between the two, and makes the adjustment process smoother and more precise. When it is necessary to adjust the length of the suspension rod 3, the user can rotate the adjustment rod 34 to move relative to the threaded part between the first pull rod 33 and the second pull rod 35, thereby changing the relative position between the two to achieve the purpose of adjusting the length.

[0055] In a specific embodiment, dense mesh holes are distributed on the gusset plate 4 and sound-absorbing cotton is arranged inside the gusset plate 4 for noise reduction.

[0056] In this embodiment, the surface of the gusset plate 4 is densely distributed with mesh holes, providing an effective channel for the propagation of sound. The sound-absorbing cotton arranged inside the gusset plate 4 is the key to the noise reduction design. The sound-absorbing cotton is a porous structure made of special materials and has excellent sound absorption performance. When the sound wave enters the interior through the mesh holes of the gusset plate 4, the sound-absorbing cotton will quickly absorb the energy in the sound wave and convert it into heat energy or other forms of energy and dissipate it, thereby achieving a noise reduction effect.

[0057] In this embodiment, the lamp trough 5 includes a first lamp trough 51 and a second lamp trough 52. A lighting lamp is specially arranged in the first lamp trough 51. In order to increase the circulation of air, an air outlet 53 is also provided on the top or side of the first lamp trough 51. This air outlet not only ensures the freshness and circulation of indoor air, but also cooperates with the air circulation system or air conditioning of the entire space. At the same time, the second lamp trough 52 is also equipped with a lighting lamp, and a return air outlet 54 corresponding to the air outlet 53 is provided. Through the synergistic effect with the air outlet 53, the circulation and renewal of indoor air are ensured.

[0058] In a specific embodiment, the light trough 5 is disposed between adjacent gusset plates 4 and connected to the keel 2 , and the gusset plates 4 adjacent to the light trough 5 are connected to the light trough 5 in an openable and closable manner.

[0059] In this embodiment, the lamp trough 5 is cleverly placed between adjacent gusset plates 4 and firmly connected to the keel 2, ensuring the stability of the lamp trough 5. In addition, an openable and closable connection is adopted between the adjacent gusset plates 4 and the lamp trough 5, which makes it easy to maintain the lamp trough 5, replace the bulb or adjust the lighting effect. When maintenance or cleaning is required, the user can easily open the gusset plates 4 adjacent to the lamp trough 5, so as to easily access the lighting equipment inside the lamp trough 5. In addition, the lamp trough 5 is tightly connected to the keel 2 through specific connectors or buckles, ensuring the stability and safety of the lamp trough 5.

[0060] In this embodiment, in order to improve the safety and functionality of the entire space, a fire relief hole 7 and a folding ladder are specially designed. The fire relief hole 7 is arranged on the outside of the gusset plate 4. When a fire occurs indoors, the fire relief hole 7 can quickly release the pressure accumulated indoors to prevent explosion or structural damage caused by excessive pressure. In addition, a folding ladder is specially installed on the keel 2 to improve the safety and functionality of the entire space.
