[0020] See also Figure 1-Figure 5A cover plate for HVAC that is easy to disassemble and assemble includes a fixing frame 1. A limit baffle 7 is fixedly welded at the center of the top and bottom of the rear side of the fixing frame 1. Insertion frames 5 are fixedly welded on the left and right sides of the inner cavity of the fixing frame 1. A cover plate body 4 is fixedly installed in the inner cavity of the fixing frame 1. A mesh plate 2 is fixedly embedded through the left side of the front surface of the cover plate body 4. By setting the mesh plate 2, normal ventilation of the HVAC can be facilitated. A mounting assembly 6 is fixedly installed on the rear side of the cover plate body 4. The mounting assembly 6 includes a plug-in plate 61. The plug-in plates 61 are respectively arranged on the cover plate body On the left and right sides of the rear side, a connecting frame 64 is fixedly welded to one side of the plug-in board 61. A limiting cylinder 65 is movably sleeved on the surface of the connecting frame 64. By setting the limiting cylinder 65, the movement of the connecting frame 64 can be limited to prevent it from shaking. The limiting cylinder 65 is fixedly welded to the rear side of the cover body 4. A pull rope 62 is fixedly connected to the side of the connecting frame 64 away from the plug-in board 61. A turntable 63 is rotatably connected to the rear side of the cover body 4 and located between the two connecting frames 64. Two pull ropes 62 are respectively fixedly connected to the top and bottom of the turntable 63.
[0021] See also Figure 3 and Figure 5 , the tail end of the plug-in board 61 is inserted into the inner cavity of the plug-in frame 5 and is in sliding contact with its inner wall, and the four corners of the front surface of the fixed frame 1 are penetrated with mounting holes;
[0022] See also Figure 3 and Figure 5 , the other side of the plug-in board 61 is fixedly connected to a tension spring 66, and the other end of the tension spring 66 is fixedly connected to a fixing plate 67, which is fixedly welded to the rear side of the cover body 4. By setting the tension spring 66, the plug-in board 61 can be automatically reset after being pulled, and can apply elastic tension to the plug-in board 61 when the plug-in board 61 is inserted into the plug-in frame 5, so as to prevent the plug-in board 61 from falling off from the plug-in frame 5;
[0023] See also Figure 1 、 Figure 2 and Figure 4 A knob is fixedly welded to the front side of the turntable 63, and the front side of the knob extends to the front side of the cover body 4. The surface of the knob and the connection point of the cover body 4 are rotatably connected through a bearing;
[0024] See also Figure 1 、 Figure 2 and Figure 4 A protective component 3 is fixedly mounted on the front surface of the cover body 4 and outside the knob, and the protective component 3 includes a protective ring 31;
[0025] See also Figure 1 、 Figure 2 and Figure 4The protective ring 31 is fixedly welded to the front surface of the cover body 4 and is located outside the knob. A protective cover 32 is installed on the top of the protective ring 31 through a rotating shaft. By setting the protective cover 32 and the protective ring 31, the knob can be protected. The protective cover 32 is fixed to the surface of the protective ring 31 with a safety lock, so that outsiders cannot turn the knob. The safety lock must be opened with a key, and the protective cover 32 must be opened before the knob can be turned. The surface of the protective cover 32 is provided with a safety lock;
[0026] See also Figure 3 The outer surface of the cover body 4 is in contact with the inner wall of the fixed frame 1, and the rear side of the cover body 4 is in contact with the front side of the limit baffle 7. By setting the limit baffle 7, the cover body 4 can be limited and blocked, so that the plug-in board 61 can be quickly positioned to the plug-in frame 5 during installation.
[0027] When in use, the fixing frame 1 is first placed on the surface of the HVAC chassis, and screws are inserted into the mounting holes to fix it on the chassis surface (this installation is only required once, and there is no need to reinstall the fixing frame 1 later). Then, the knob is turned to drive the turntable 63 to rotate and drive the two pull ropes 62 to reel, thereby pulling the connecting frame 64 to move, so that it drives the plug-in board 61 to move out of the plug-in frame 5. Then, the knob is released, and the cover body 4 can be quickly pulled forward from the inside of the fixing frame 1 to achieve the disassembly effect. When it needs to be installed again, the knob is turned again to pull the plug-in board 61 to the disassembly state position. The plug-in board 61 drives the tension spring 66 to stretch, and then the cover body 4 is placed in the fixing frame 1 so that the rear side of the cover body 4 contacts the front side of the limit baffle 7. The knob is released and the tension of the tension spring 66 is used to reset the plug-in board 61 to reset and insert it into the plug-in frame 5 to achieve installation. Then, the protective cover 32 is covered on the surface of the protective ring 31 and locked with a safety lock to prevent unauthorized operation by non-related personnel.
[0028] To sum up: this HVAC cover that is easy to disassemble and assemble, through the cooperation of the fixing frame 1, the cover body 4, the insertion frame 5, the installation component 6 and the limit baffle 7, solves the problem that the current HVAC cover is usually fixed to the surface of the HVAC chassis by screws. When the air conditioner is damaged or there are many contaminants on the surface of the cover, multiple screws need to be manually removed one by one, and the operation process is relatively complicated, time-consuming and labor-intensive.
