The guide frame is fixedly installed in the frame of the second docking frame, and the rubber baffle is fixedly installed in the frame of the first docking frame, and the outer wall of the rubber baffle is abutted against the guide frame.

[0013] Optionally, the rubber baffle adopts a hollow prism-shaped structure, and the rubber baffle is inserted into the frame of the second docking frame, and air flows into the second air duct through the first air duct.

[0029] Example 1

[0030] This embodiment provides a flexible polyurethane foam rubber installation structure for sealing air conditioning ducts, such as Figure 1 and Figure 2As shown, the air duct includes a first air duct 1 and a second air duct 3. The ends of the first air duct 1 and the second air duct 3 are butted together. A first butting frame 2 is fixedly mounted on the end of the first air duct 1, and a second butting frame 4 is fixedly mounted on the end of the second air duct 3. A foam rubber 5 is sandwiched between the first butting frame 2 and the second butting frame 4. The foam rubber 5 is installed between the first butting frame 2 and the second butting frame 4 to fill the gap and prevent air leakage in the air conditioning duct.

[0031] Further, such as Figure 2 and Figure 3 As shown, a mounting assembly 6 is provided on the first docking frame 2, and the mounting assembly 6 includes an iron rod 61, an insulating positioning cylinder 62, a slider 65 and a tooth plate 66. The inner wall of the insulating positioning cylinder 62 is slidably connected to the iron rod 61, and the insulating positioning cylinder 62 passes through the first docking frame 2, the second docking frame 4 and the foam rubber 5, so that the positions of the first docking frame 2, the second docking frame 4 and the foam rubber 5 are aligned.

[0032] The side of the second docking frame 4 is slidably connected to a slider 65. Two symmetrically arranged slots 63 are defined in the middle of the insulating positioning tube 62, and the sliders 65 engage with the slots 63. A limit plate is fixedly mounted on the end of the iron rod 61. Because the insulating positioning tube 62 holds the first docking frame 2, the second docking frame 4, and the foam rubber 5 together, the iron rod 61 is fixed in position within the insulating positioning tube 62. The magnetic force of the slider 65 forces it to fit within the slot 63. The slider 65 and the limit plate cooperate to clamp the first docking frame 2, the second docking frame 4, and the foam rubber 5. The distance between the limit plate and the slider 65 is adjusted by sliding the iron rod 61 within the insulating positioning tube 62.

[0033] Furthermore, a toothed plate 66 is fixedly mounted on the side of the slider 65 facing the insulating positioning tube 62. The iron rod 61 is provided with a plurality of annular grooves 64, which are evenly spaced along the iron rod 61. The toothed plate 66 engages with the annular grooves 64. The engagement of the toothed plate 66 with the annular grooves 64 fixes the position of the iron rod 61, thereby maintaining a fixed length for the iron rod 61 and the insulating positioning tube 62.

[0034] In this embodiment, the iron rod 61 slides in the insulating positioning tube 62, and the distance between the limit plate and the slider 65 is adjusted according to the thickness of the first docking frame 2, the second docking frame 4 and the foam rubber 5. The tooth plate 66 engages with the annular groove 64 to fix the position of the iron rod 61, so that the overall length of the iron rod 61 and the insulating positioning tube 62 is fixed. Since the slider 65 is adsorbed on the insulating positioning tube 62, when vibrating, the slider 65 is restored to its state in time under the action of the magnetic force, thereby preventing the foam rubber 5 from being loosened during installation.

[0035] Example 2

[0036] Based on Example 1, this embodiment proposes a flexible polyurethane foam rubber installation structure for sealing air ducts of air conditioners, such as Figure 2 and Figure 4 As shown, a sealing assembly 7 is provided in the frame of the first docking frame 2, and the sealing assembly 7 includes a rubber baffle 71 and a guide frame 72. The guide frame 72 is fixedly installed in the frame of the second docking frame 4, and the rubber baffle 71 is fixedly installed in the frame of the first docking frame 2, and the outer wall of the rubber baffle 71 is abutted against the guide frame 72.

[0037] Among them, the rubber baffle 71 adopts a hollow prism-shaped structure. The rubber baffle 71 is inserted into the frame of the second docking frame 4. Wind flows into the second air duct 3 inside the first air duct 1. The guide frame 72 is provided with a docking groove 73 on the side facing the rubber baffle 71, and the rubber baffle 71 is embedded in the docking groove 73.

[0038] When wind flows through the first air duct 1 and the second air duct 3 , the rubber baffle 71 is pressed against the guide frame 72 by the wind force, and the left end of the rubber baffle 71 extends from the left end of the guide frame 72 .

[0039] like Figure 4 As shown, an extension piece is fixedly installed in the frame of the foam rubber 5. The two ends of the extension piece are respectively installed in the frame of the first docking frame 2 and the frame of the second docking frame 4. The extension piece is located between the rubber blocking piece 71 and the guide frame 72. The extension piece fills the gap between the first docking frame 2 and the second docking frame 4, and the rubber blocking piece 71 and the guide frame 72 surround the extension piece.

[0040] In this embodiment, when wind flows through the first air duct 1 and the second air duct 3, the rubber baffle 71 is pressed against the guide frame 72 by the wind force, and the wind force reduces the distance between the rubber baffle 71 and the guide frame 72. At the same time, the left end of the rubber baffle 71 extends from the left end of the guide frame 72. Under the action of wind force, the rubber baffle 71 bends along the left end edge of the guide frame 72, further improving the sealing effect.

[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
