[0065] The following describes in detail an airtight ceiling keel that is easy to disassemble and assemble according to an embodiment of the utility model with reference to the accompanying drawings.

[0066] Reference Figures 1 to 5 As shown, according to an embodiment of the utility model, an airtight ceiling keel that is easy to disassemble and assemble is provided, which is used to install high-side aluminum gusset plates and includes a main keel 10, a secondary keel 20 and a clamping member 30.

[0067] The main keel 10 is connected to the roof via a suspension rod 101 .

[0068] The secondary keel 20 is connected to the lower part of the main keel 10, and the bottom surface of the secondary keel 20 is recessed inward to form an installation gap C1. The main keel 10 and the secondary keel 20 extend perpendicularly to each other to improve the bearing capacity of the overall structure.

[0069] The clamping member 30 includes a connecting piece 301 and two clamping pieces 302. Both ends of the connecting piece 301 are bent downward to define a first clamping gap C2 between the two ends of the connecting piece 301. The upper end of the connecting piece 301 is detachably arranged in the installation gap C1. The two clamping pieces 302 are respectively integrally formed at both ends of the connecting piece 301. The lower ends of the two clamping pieces 302 are obliquely bent upward and close to each other to define a second clamping gap C3 between the two clamping pieces 302.

[0070] During installation, the edge of the high-side aluminum gusset plate is inserted into the first clamping gap C2 and the second clamping gap C3 at the same time. It should be noted that the width of the first clamping gap C2 and the second clamping gap C3 is smaller than the thickness of the edge of the high-side aluminum gusset plate. During installation, the clamping sheet 302 and the connecting sheet 301 are squeezed to deform them, and then the edge of the high-side aluminum gusset plate is clamped by the elastic force generated by the deformation.

[0071] Based on the above, by setting an integrally formed clamping member 30, and forming the first clamping gap C2 and the second clamping member 30 in the clamping member 30, during installation, the edge of the high-side aluminum gusset plate can be inserted into the first clamping gap C2 and the second gap. Its installation and disassembly are more portable and labor-saving, which is conducive to multiple uses. The integrally formed clamping member 30 can enable the two high-side aluminum gusset plates to maintain good air tightness after installation, which is more conducive to meeting the installation requirements of the operating room. It has strong practicality and good use effect.

[0072] Preferably, in an embodiment of the present invention, the secondary keel 20 includes a main body portion 201 and a mounting portion 202 .

[0073] The main body 201 is in an “n” shape and is connected to the lower side of the main keel 10 .

[0074] Two ends of the mounting portion 202 are connected to two ends of the main body 201 , and the middle portion of the mounting portion 202 is recessed upward to form the mounting gap C1 .

[0075] In this way, the connection between the main body portion 201 and the mounting portion 202 allows the entire secondary keel 20 to form a hollow structure, which ensures strength and reduces installation costs. At the same time, since the mounting portion 202 is recessed upward to form the mounting gap C1, it ensures connection with the clamping member 30 while reducing the thickness of the entire mounting portion 202 and the clamping member 30 after installation.

[0076] At the same time, by designing the main body 201 as an "n"-type structure, the upper part has a physical isolation sealing performance, which can prevent dust particles, bacteria and other microorganisms on the ceiling from entering the clean room under the ceiling, avoiding affecting the environment in the clean room.

[0077] Preferably, in an embodiment of the present utility model, the mounting portion 202 includes two first bending portions 2021 , two first extending portions 2022 and one first arc-shaped portion 2023 .

[0078] One end of the two first bending portions 2021 is connected to two ends of the main body 201 , respectively, and the other end extends toward the inside of the main body 201 and forms an angle less than 90° with the side surface of the main body 201 .

[0079] One ends of the two first extension portions 2022 are respectively connected to the other ends of the two first bending portions 2021 , and the other ends of the two first extension portions 2022 extend vertically.

[0080] Two ends of the first arc portion 2023 are respectively connected to the other ends of the two first extension portions 2022 .

[0081] The diameter of the first arc portion 2023 is greater than the distance between the two first extension portions 2022 .

[0082] In this way, one end of the two first bending portions 2021 is respectively connected to the two ends of the main body 201, and the other end extends toward the inner side of the main body 201 and forms an angle less than 90° with the side surface of the main body 201, and one end of the two first extension portions 2022 is respectively connected to the other end of the two first bending portions 2021, and the other end of the two first extension portions 2022 extends vertically, thereby defining an installation gap C1 to facilitate the connection of the clamping sheet 302 thereto.

[0083] Preferably, in an embodiment of the present utility model, the connecting piece 301 includes a second arc-shaped portion 3011 , two second extending portions 3012 and two fitting portions 3013 .

[0084] The second arc-shaped portion 3011 is suitable for being inserted into the inner side of the first arc-shaped portion 2023 .

[0085] One end of the two second extension portions 3012 is respectively connected to two ends of the second arc-shaped portion 3011 , and the other end extends vertically downward.

[0086] The upper ends of the two fitting portions 3013 are connected to the lower ends of the two first extending portions 2022 , and the two fitting portions 3013 extend downward and away from each other.

[0087] Thus, since the two ends of the first arc-shaped portion 2023 are respectively connected to the other ends of the two first extensions 2022, and the second arc-shaped portion 3011 is suitable for being inserted inside the first arc-shaped portion 2023, the second arc-shaped portion 3011 can be inserted inside the first arc-shaped portion 2023 during connection, and the two second extensions 3012 can be located between the two first extensions 2022. At the same time, since the diameter of the first arc-shaped portion 2023 is greater than the distance between the two first extensions 2022, the second arc-shaped portion 3011 can be stably confined inside the first arc-shaped portion 2023, so that the secondary keel 20 and the clamping member 30 are connected, and the connection method is portable and reliable.

[0088] At the same time, since one end of the two first bending portions 2021 is connected to the two ends of the main body 201, and the other end extends to the inner side of the main body 201 and forms an angle less than 90° with the side surface of the main body 201, and the upper ends of the two fitting portions 3013 are connected to the lower ends of the two first extension portions 2022, the two fitting portions 3013 extend downward and move away from each other, that is, the two first bending portions 2021 and the fitting portions 3013 are both formed into an "eight" shape, so that when the secondary keel 20 and the clamping member 30 are connected, the bottom surface of the first bending portion 2021 and the surface of the fitting portion 3013 fit each other to compress the two fitting portions 3013;

[0089] As mentioned above, the width of the first clamping gap C2 and the second clamping gap C3 is smaller than the thickness of the edge of the high-side aluminum gusset plate. During installation, the clamping plate 302 and the connecting plate 301 are squeezed to deform them, and then the elastic force generated by the deformation is used to clamp the edge of the high-side aluminum gusset plate. Then, during installation, the first bending portion 2021 can press the clamping member 30, so that the edge of the high-side aluminum gusset plate is stronger and the installation is more stable and reliable.

[0090] Preferably, in an embodiment of the present invention, the two clamping pieces 302 both include a third extending portion 3021 and a second bending portion 3022 .

[0091] The two third extension portions 3021 are respectively vertically connected below the two second extension portions 3012 .

[0092] The second bending portion 3022 is “L-shaped”, with one end of the second bending portion 3022 connected to the lower end of the third extension portion 3021 , and the other end extending between the two third extension portions 3021 and forming an angle less than 90° between the second bending portion 3022 and the third extension portion 3021 .

[0093] Thus, since the second bending portion 3022 is "L-shaped", one end of the second bending portion 3022 is connected to the lower end of the third extension portion 3021, and the other end extends between the two third extension portions 3021 and forms an angle less than 90° with the third extension portions 3021, then the second clamping gap C3 can be defined by the two second bending portions 3022 to clamp the edge of the high-side aluminum gusset plate;

[0094] At the same time, since one end of the second bending portion 3022 is connected to the lower end of the third extension portion 3021, and the other end extends between the two third extension portions 3021 and forms an angle less than 90° with the third extension portion 3021, the second bending portion 3022 can be made into an "eight" shape, so that a triangular installation opening is formed at the lower end of the first clamping gap C2. During installation, the edge of the high-side aluminum gusset plate can be quickly inserted into the first clamping gap C2, making the installation of the high-side aluminum gusset plate faster.

[0095] Preferably, in one embodiment of the utility model, the main keel 10 is provided with a first connecting hole 102, the secondary keel 20 is provided with a second connecting hole 203, the lower end of the suspension rod 101 passes through the first connecting hole 102 and the second connecting hole 203, and extends into the secondary keel 20, the lower end of the suspension rod 101 is provided with a nut 103, and the nut 103 is located in the secondary keel 20.

[0096] In this way, by providing a first connecting hole 102 on the main keel 10 and a second connecting hole 203 on the secondary keel 20, during installation, the lower end of the suspension rod 101 can be passed through the first connecting hole 102 and the second connecting hole 203 and extended into the secondary keel 20, and then limited by the nut 103, so that the main keel 10 and the secondary keel 20 are connected and suspended on the roof, and the installation and disassembly are convenient and quick.

[0097] Preferably, in an embodiment of the present utility model, the clamping member 30 is made of elastic manganese steel.

[0098] In this way, when installing the high-side aluminum gusset plate, the clamping member 30 can be pressurized and deformed, thereby generating elastic force to clamp and fix the high-side aluminum gusset plate.
