DETAILED DESCRIPTION

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 and Figure 2As shown, the utility model provides an air damper, comprising a body 1, at least two baffles 2, a rotating shaft structure 3 and a driving member 4, wherein the body 1 has an air outlet 11, and the rotating shaft structure 3 is mounted on the body 1; the rotating shaft structure 3 comprises a driving shaft structure 31, at least one driven shaft structure 32 and at least one linkage structure 33 located outside the body 1, and the driving shaft structure 31 and the driven shaft structure 32 are arranged along a first direction (such as Figure 2 The driving shaft structure 31 is connected to the driven shaft structure 32 through a linkage structure 33, and the driving shaft structure 31 and the driven shaft structure 32 are both provided with a baffle 2 to open or cover the air outlet 11 as the driving shaft structure 31 rotates.

[0027] Based on the above structure, this embodiment places the linkage structure 33 outside the main body 1, so that the linkage structure 33 is easier to inspect and maintain. If damage occurs, it can be replaced more conveniently without having to disassemble the entire air damper. While the driving shaft structure 31 is driven to rotate by the driving member 4, the linkage structure 33 is driven to synchronously drive the driven shaft structure 32 to rotate, and then the position of the baffle 2 is controlled to open or close the air outlet 11. At the same time, the amount of air entering the cabin can be effectively adjusted to ensure that the equipment operates under optimal conditions.

[0028] Furthermore, there are two driven shaft structures 32 and two linkage structures 33. The two driven shaft structures 32 are arranged on both sides of the driving shaft structure 31. One end of the linkage structure 33 is connected to the driving shaft structure 31, and the other end of the linkage structure 33 is connected to the corresponding driven shaft structure 32.

[0029] This embodiment utilizes two driven shaft structures 32 and a corresponding linkage structure 33 to ensure synchronized movement of all baffles 2, evenly regulating air flow and avoiding uneven ventilation caused by asynchronous movement of individual baffles 2. Furthermore, the design of multiple driven shaft structures 32 and linkage structures 33 allows for more precise movement of the baffles 2, enabling better control of the amount of air entering the cabin and ensuring optimal equipment operation.

[0030] It should be noted that each driven shaft structure 32 and linkage structure 33 is an independent module. If a part fails, it can be replaced separately without disassembling the entire damper. This greatly simplifies maintenance work and reduces maintenance costs and time.

[0031] Furthermore, the driving shaft structure 31 includes a first rotating shaft 311, a first shaft sleeve 312, and a first bevel gear 313 that is cooperatively connected to the linkage structure 33. The first rotating shaft 311 is provided on opposite sides of the body 1, and one end of the first rotating shaft 311 is connected to the first shaft sleeve 312. The first shaft sleeve 312 plays a supporting and fixing role. The other end of the first rotating shaft 311 is connected to the driving member 4, and the first bevel gear 313 is installed on the end of the first rotating shaft 311 facing the driving member 4 for transmitting power.

[0032] The driven shaft structure 32 includes a second rotating shaft 321, a second shaft sleeve 322 and a second bevel gear 323 connected to the linkage structure 33. The second rotating shaft 321 is arranged on opposite sides of the main body 1, and one end of the second rotating shaft 321 is connected to the second shaft sleeve 322. The second shaft sleeve 322 plays a supporting and fixing role. The other end of the second rotating shaft 321 is installed with a second bevel gear 323 to receive power from the driving shaft structure 31.

[0033] Based on the above structure, this embodiment transmits the rotational power provided by the driving member 4 from the driving shaft structure 31 to the driven shaft structure 32 through the engagement of the bevel gears. The design of the bevel gears can change the direction of power transmission, so that the power can be converted from the horizontal direction to the vertical direction.

[0034] Furthermore, the linkage structure 33 includes a mounting frame (not shown in the figure), a connecting shaft 331, a third bevel gear 332 meshing with the first bevel gear 313, and a fourth bevel gear 333 meshing with the second bevel gear 323. The third bevel gear 332 and the fourth bevel gear 333 are respectively installed at both ends of the connecting shaft 331. The third bevel gear 332 is used to receive power from the driving member 4, and the fourth bevel gear 333 is used to transmit power to the driven shaft structure 32. The mounting frame is connected to the side of the main body 1, and the side of the mounting frame facing away from the main body 1 is movably connected to the connecting shaft 331, allowing the connecting shaft 331 to rotate freely within a certain range.

[0035] Based on the above structure, this embodiment transmits the rotational power provided by the driving member 4 from the active shaft structure 31 to the connecting shaft 331 through the engagement of the third bevel gear 332 with the first bevel gear 313, and transmits the power on the connecting shaft 331 to the driven shaft structure 32 through the engagement of the fourth bevel gear 333 with the second bevel gear 323, so that the driven shaft structure 32 rotates synchronously with the active shaft structure 31. Through the linkage of the above-mentioned linkage structure 33, it is ensured that all baffles 2 can move synchronously, thereby achieving precise control of the air flow.

[0036] Compared to existing systems that require regular lubrication through a grease nipple to reduce friction and wear between the shaft and sleeve, the first and second sleeves 312 and 322 of this embodiment are made of tin bronze, while the first and second rotating shafts 311 and 321 are made of stainless steel. The tin bronze forms a lubricating film on the surface during friction, reducing friction and wear. This ensures excellent corrosion resistance in high-humidity and high-salt environments, maintaining its performance over time. Furthermore, stainless steel exhibits excellent corrosion and wear resistance, allowing it to withstand long-term use in harsh marine environments without rusting. The combination of stainless steel and tin bronze further reduces friction and wear, extending the service life of the damper.

[0037] In this embodiment, by using a tin bronze bushing and a stainless steel shaft, the damper can achieve a self-lubricating function without the need for regular oiling, thereby achieving a maintenance-free structure, simplifying maintenance work, and reducing the risk of failure due to improper maintenance.

[0038] Furthermore, the driving member 4 is a hand wheel that can be manually rotated by the operator to adjust the opening and closing degree of the baffle 2. This design makes the operation simple and intuitive, and does not require a complex electrical or hydraulic system. In addition, as needed, the driving member 4 can be driven by a motor, a cylinder, or other driving member 4, which is not particularly limited here.

[0039] See also Figure 3 and Figure 4 , further comprising a limiting structure 5 for limiting the rotation of the linkage structure 33. The limiting structure 5 is mounted on the side of the body 1 facing the rotating shaft structure 3. In this embodiment, the limiting structure 5 limits the third bevel gear 332 of the linkage structure 33 to prevent the baffle 2 from excessively opening or closing during the adjustment process. The opening and closing degree of the baffle 2 can also be controlled as needed to achieve different airflow rates.

[0040] Furthermore, the limiting structure 5 includes a mounting member 51, a connecting member 52, a limiting member 53, a rotating member 54 and an elastic member 55. The mounting member 51 is installed on the side of the main body 1 for fixing the entire limiting structure 5. The limiting member 53 and the mounting member 51 are spaced apart and arranged on one side of the main body 1. One end of the connecting member 52 passes through the mounting member 51 and is connected to the limiting member 53. The elastic member 55 is sleeved on the circumferential side of the connecting member 52, and one end of the elastic member 55 abuts against the mounting member 51, and the other end of the elastic member 55 abuts against the limiting member 53. The rotating member 54 is rotatably connected to the other end of the connecting member 52, so that the limiting member 53 is driven to abut against or away from the third bevel gear 332 as the rotating member 54 rotates.

[0041] Based on the above structure, since each tooth position of the bevel gear can serve as a limit point, the limit member 53 can contact different tooth positions, achieving multi-level limit, providing more precise adjustment capabilities and allowing different rotation ranges to be set according to actual needs. In addition, the limit structure 5 can set the maximum and minimum rotation angles of the driven shaft structure 32 by abutting or separating the limit member 53 from the third bevel gear 332, preventing the baffle 2 from opening or closing excessively. This helps protect the mechanical components of the air damper and avoid damage caused by excessive rotation.

[0042] When the rotating member 54 rotates, the limiting member 53 will abut against or move away from the third bevel gear 332. When the rotating member 54 returns to the initial position, the elastic member 55 will automatically reset the limiting member 53 to ensure that the limiting structure 5 is always in the correct working state.

[0043] Furthermore, the rotating member 54 includes a driving section 541 and a spherical section 542 connected to the driving section 541. The driving section 541 is a manually operated portion, typically a handle or similar structure. An operator can adjust the position of the limit member 53 by rotating the driving section 541. The spherical section 542 is rotatably connected to the connecting member 52. The connection point between the connecting member 52 and the spherical section 542 is spaced apart from the center of the spherical section 542 and the heights of the two are substantially flush. That is, the connection point of the connecting member 52 and the center of the spherical section 542 form an eccentric distance, allowing the spherical section 542 to rotate freely within a certain range while maintaining the stability of the connecting member 52.

[0044] When the driving segment 541 abuts the mounting member 51, the stopper 53 and the third bevel gear 332 do not contact each other. At this time, the driven shaft structure 32 can rotate freely without being restricted by the stopper 53. When the spherical segment 542 abuts the mounting member 51, the stopper 53 abuts the third bevel gear 332. At this time, the rotation of the driven shaft structure 32 is restricted by the stopper 53, preventing excessive rotation. In this embodiment, the position of the stopper 53 can be easily adjusted by rotating the driving segment 541, thereby achieving precise control over the rotation range of the driven shaft structure 32.

[0045] Furthermore, the baffle 2 includes a first plate 21 and a second plate 22 installed at both ends of the first plate 21. The first plate 21 serves as a main wind shield for adjusting the amount of air entering the cabin. A first angle is formed between the first plate 21 so that when the first plate 21 rotates to a specified position, it is hooked with the second plate 22 of the adjacent first baffle 2. The air regulating door also includes a limiting plate 6 for limiting the second plate 22 to prevent the second plate 22 from exceeding a predetermined range during rotation. The limiting plates 6 are arranged at opposite ends of the main body 1 to ensure that the second plate 22 is limited to the specified position when it rotates to the specified position, thereby achieving covering of the air outlet 11.

[0046] To sum up, the embodiment of the utility model provides an air regulating door, which is driven by a handle outside the air regulating door and a linkage structure 33 to realize a linkage connection between multiple baffles 2, and to transfer the rotating pair of the baffle 2 from a high-moisture environment to a low-moisture environment. When the air regulating door is inspected and repaired, there is no need to remove the air regulating door, and the corrosion-prone linkage plate can be maintained and repaired, thereby further improving the service life of the product and reducing maintenance costs.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
