DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0041] like Figures 1 to 7 As shown, a laminar air supply ceiling system includes a bottom plate 1 and an air guide tube 2 detachably mounted on the upper surface of the bottom plate 1, and a top plate 3 is fixedly mounted on the air inlet end of the air guide tube 2. The laminar air supply ceiling system also includes:

[0042] The side plate 4 is arranged between the bottom plate 1 and the top plate 3 .

[0043] The convex strips 5 fixed on the opposite surfaces of the bottom plate 1 and the top plate 3 are plugged into the mounting grooves 6 arranged on the upper surface or the lower surface of the side plate 4. The two opposite convex strips 5 and the same side surface of the side plate 4 together form a side straight surface 7.

[0044] A scissor-type bracket 9 is fixedly connected to the limiting groove 8 provided on the side straight surface 7, and the scissor-type bracket 9 is used to fix the bottom plate 1, the top plate 3 and the side plate 4.

[0045] The above five parts can be classified and packed separately during transportation, so that they can be neatly stacked and piled during transportation, and are also easy to carry. Compared with the three-dimensional module of the pre-supported laminar air supply ceiling system, it is split into five parts, which occupies less space during transportation and is not easily deformed and unusable due to external forces, affecting the subsequent overall assembly operation. In addition, the assembly difficulty between the five parts is small, the efficiency is high, and they can be assembled into an independent module. The assembly operation of the five parts has little effect on the overall assembly efficiency and can be ignored.

[0046] like Figure 1 , Figure 2 and Figure 6As shown, in this embodiment, the laminar air supply ceiling system also includes a fixing bolt 16 for threadedly fixing the scissor-type bracket 9 and the limiting groove 8, and the limiting groove 8 is composed of a groove on the end face of the convex strip 5 and a groove on the side panel 4. The four ends of the scissor-type bracket 9 can be fixed respectively inside the limiting groove 8 located at the four corners of the side straight surface 7 through the fixing bolt 16. Through the mutual constraint between the limiting groove 8 and the scissor-type bracket 9, the bottom plate 1, the top plate 3 and the side panel 4 can be fixed together to form a three-dimensional module, so that the three-dimensional module can be installed on the reserved slot on the prefabricated frame pre-supported on the roof.

[0047] like Figure 3 and Figure 5 As shown, in this embodiment, the laminar air supply ceiling system also includes:

[0048] A bottom sealing plate 11 is mounted on at least one vent 12 provided on the bottom plate 1 .

[0049] A protrusion 13 fixed on the edge of the bottom sealing plate 11 is plugged into a slot 14 provided on the inner wall of the vent 12 .

[0050] A limiting member 15 is used to fix the bottom sealing plate 11 .

[0051] like Figures 2 to 4 As shown, in this embodiment, the limiting member 15 includes:

[0052] A slide bar 152 is slidably connected to a transverse slide groove 151 disposed on the inner wall of the slot 14 .

[0053] The transverse compression spring 153 is slidably mounted on one end of the slide rod 152 , and the transverse compression spring 153 is located between the end of the slide rod 152 and the inner end surface of the transverse slide groove 151 . The protrusion 13 is provided with a socket 156 that matches the other end of the slide rod 152 .

[0054] A lever 154 is fixedly mounted on the surface of the slide bar 152 , and one end of the lever 154 is slidably connected to a strip groove 155 provided between the bottom plate 1 and the horizontal slide groove 151 .

[0055] When installing the bottom sealing plate 11, first pull the lever 154 in the direction of the transverse compression spring 153, so that the transverse compression spring 153 undergoes elastic shortening deformation and completely retracts the slide bar 152 into the transverse slide groove 151, and then aligns the protrusion 13 and the slot 14 into the set vent 12, and then releases the hand pulling the lever 154. Under the elastic force of the transverse compression spring 153, the slide bar 152 is reset and one end of the slide bar is inserted into the socket 156 on the protrusion 13, thereby fixing the bottom sealing plate 11 in the vent 12 and simplifying the installation steps of the bottom sealing plate 11.

[0056] like Figure 3 and Figure 4As shown, in the present embodiment, the lever 154 is perpendicular to the lower surface of the bottom plate 1, and the lever 154 is located between the transverse compression spring 153 and the slot 14. Under the elastic force of the transverse compression spring 153, one end of the slide rod 152 close to the slot 14 passes through one end of the transverse slide groove 151 and extends into the slot 14, so that after the bottom sealing plate 11 is installed in the vent 12, one end of the slide rod 152 can be plugged into the socket 156 on the protrusion 13 to fix the bottom sealing plate 11, reduce the difficulty of installing the bottom sealing plate 11, and facilitate the disassembly, maintenance or replacement of the bottom sealing plate 11 in the later stage.

[0059] A vertical rod 102 is slidably connected to a through hole 101 provided on the bottom plate 1 .

[0060] A limiting support plate 104 is fixed to the bottom end of the vertical rod 102 .

[0061] The vertical compression spring 103 is slidably mounted on the outside of the vertical rod 102 , and is located between the upper surface of the bottom plate 1 and the top of the vertical rod 102 . A limit plate is fixedly installed on the top of the vertical rod 102 , and the limit plate is used to limit the vertical compression spring 103 from detaching from the vertical rod 102 .

[0062] After the independent module is assembled between the bottom plate 1, the air guide tube 2, the top plate 3, the side plate 4 and the scissor-type bracket 9, the independent module is stood up and passed through the reserved slot on the prefabricated frame from bottom to top, and then the independent module is turned over to a horizontal state and placed in the reserved slot, and then the limiting support plate 104 is pulled down so that the upper surface height of the limiting support plate 104 is lower than the lower surface height of the prefabricated frame, and then the limiting support plate 104 is rotated until its upper surface is below the lower surface of the prefabricated frame, and then the hand holding the limiting support plate 104 is released. The limiting support plate 104 is pressed against the lower surface of the prefabricated frame under the elastic force of the vertical compression spring 103, thereby realizing the fixed installation operation between the independent module and the prefabricated frame, and also facilitating the maintenance, inspection or replacement of the independent module in the later stage.

[0063] like Figure 1 and Figure 7As shown, in this embodiment, the laminar air supply ceiling system also includes a docking port 17 provided on the top plate 3, the docking port 17 is connected to the air inlet end of the air duct 2, and at least two fan mounting holes 18 are provided on the top plate 3 around the boundary of the docking port 17. The fan mounting holes 18 are provided for the convenience of the installer to fix the fan unit to the upper surface of the top plate 3 by means of mounting bolts, so as to facilitate the later delivery of the airflow after multiple purifications into the air duct 2, and transport it to the room through the air duct 2, and the surface of the fan unit can also be fixedly connected to the roof by adding a plurality of zippers or pull rods, so that the gravity of the fan unit and the vibration force during operation are shared by the zippers or pull rods, thereby improving the stability of the fan unit during operation.

[0064] like Figure 3 and Figure 5 As shown, in this embodiment, the laminar air supply ceiling system also includes:

[0065] A filter screen 20 is fixed at the center of the bottom sealing plate 11 .

[0066] The light emitting panels 19 are fixed at the four corners of the bottom sealing plate 11 and are distributed around the filter screen 20. During installation, the connection terminals of the light emitting panels 19 are electrically connected to the power supply through wires.
