DETAILED DESCRIPTION

[0023] The utility model discloses a kind of rust-prevention air doors, below Preferred Embodiment (Example 1), referring to the Figures 1 to 8 , the specific embodiment of the utility model is further described.

[0024] Referring to the Figures 1 to 8 , Figures 1 to 4 rust-prevention air doors of different visual angle are respectively shown, Figure 5 and Figure 6 rotating assembly and linkage rod are respectively shown, Figure 7 and Figure 8 part structure of rotating assembly and linkage rod is respectively shown.

[0025] Example 1.

[0026] Preferably, rust-prevention air door includes frame 100, rotating assembly 200 and four follower assemblies 300, wherein:

[0027] Frame 100 is built-in air duct 101, rotating assembly 200 and follower assembly 300 are built-in air duct 101, by rotating rotating piece 220 and follower piece 320, the opening and closing degree of air duct 101 can be changed;

[0028] Rotating assembly 200 includes linkage rod 201, handle 202, rotating rod 210, rotating piece 220, first support 230 and first connecting piece 240, handle 202 is fixedly connected with rotating rod 202, rotating rod 210 is rotatably connected with frame 100, rotating rod 210 is fixedly connected with rotating piece 220, rotating piece 220 is fixedly connected with first support 230, first support 230 is dampingly connected with first connecting piece 240 (first support 230 is rotatably connected with first connecting piece 240, but there is damping in rotating process), first connecting piece 240 is fixedly connected with linkage rod 201;

[0029] The driven assembly 300 includes a driven rod 310, a driven piece 320, four second support members 330, and four second connectors 340. The driven rod 310 is rotatably connected to the frame 100, the driven rod 310 is fixedly connected to the driven piece 320, the driven piece 320 is fixedly connected to the second support member 330, the second support member 330 is dampedly connected to the second connector 340 (the second support member 330 and the second connector 340 are rotatably connected but damped during rotation), and the second connector 340 is fixedly connected to the connecting rod 201.

[0030] The handle 202 drives the rotating rod 210 and the rotating plate 220 to rotate, which in turn drives the connecting rod 201 to move, which in turn drives the driven rod 310 and the driven plate 320 to rotate. This allows the user to manually turn the handle 202 to achieve synchronous rotation of the rotating plate 220 and the driven plate 320, thereby adjusting the opening and closing degree of the air duct 101.

[0031] As a supplement, when the rotating plate 220 and the driven plate 320 rotate to a horizontal position simultaneously ( Figures 1 to 4 The rotating plate 220 and driven plate 320 shown are not yet rotated to a horizontal position. When they are exactly adjacent to each other, it is equivalent to completely closing the air duct 101. When the rotating plate 220 and driven plate 320 rotate to a position deviating from the horizontal, the greater the deviation, the higher the degree of opening of the air duct 101. When both rotating plate 220 and driven plate 320 rotate to a vertical position simultaneously, it is equivalent to opening the air duct 101 to its maximum extent.

[0032] Based on this, the degree of openness of the air duct 101 is positively correlated with the airflow through the air duct 101, and the airflow is directly related to the degree of corrosion. Simply installing anti-corrosion dampers at room ventilation openings or other locations can regulate the degree of corrosion of items within the room.

[0033] The rotating plate 220 includes a first rotating plate body 221 and a second rotating plate body 222 symmetrically distributed relative to the rotating rod 210, and the first rotating plate body 221 and the second rotating plate body 222 are respectively fixedly connected to the rotating rod 210.

[0034] The driven piece 320 includes a first driven piece 321 and a second driven piece 322 symmetrically distributed relative to the driven rod 310, and the first driven piece 321 and the second driven piece 322 are respectively fixedly connected to the driven rod 310.

[0035] The frame 100 comprises an auxiliary positioning plate 110 and a frame body 120, the rotating rod 210 is rotationally connected with the auxiliary positioning plate 110, and the auxiliary positioning plate 110 is fixedly connected with the frame body 120, so as to assist in indicating the rotating angle of the handle 202.

[0036] The auxiliary positioning plate 110 is provided with an arc-shaped groove 111, so as to intuitively indicate the rotating angle of the handle 202.

[0037] The surfaces of the linkage rod 201, the rotating rod 210, the rotating piece 220, the driven rod 310 and the driven piece 320 are provided with an anti-rust coating (not shown in the figure), so as to improve the anti-rust ability of the anti-rust damper.

[0038] Embodiment 2.

[0039] The difference between Embodiment 2 and Embodiment 1 is that Embodiment 1 is limited to four driven assemblies 300, while Embodiment 2 is not limited to four driven assemblies 300, but can be equipped with any number of driven assemblies 300 according to actual needs. The working principle of the driven assemblies 300 driven by the rotating assembly 200 remains unchanged.

[0040] It is worth mentioning that the specific structure (components) of the anti-rust coating and other technical features involved in the utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected conventionally in the art, and should not be regarded as the invention point of the utility model patent. The utility model patent will not be further expanded and described in detail.

[0041] For those skilled in the art, the technical solutions described in the foregoing embodiments can still be modified or some technical features can be replaced equivalently. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
