A regulating damper for multiple air outlets

Abstract

This utility model relates to the field of ventilation control technology, and in particular to an adjustable damper for multiple air vents. The adjustable damper for multiple air vents includes a support plate, vertical plates, a wind force adjustment mechanism, and a wind-resistant mechanism. There are two support plates, with two symmetrically distributed vertical plates fixedly connected between them. This utility model significantly improves the stability and durability of the damper under strong wind conditions by setting a wind-resistant mechanism within the adjustment groove. Both sides of the stabilizing groove are connected to an arc-shaped plate via springs, allowing the arc-shaped plate to move freely along the direction of the springs. During operation, when the wind force is strong enough to cause the rotating shaft to contact the arc-shaped plate, the arc-shaped plate, under the action of the springs, provides a certain damping effect on the rotating shaft, thereby preventing excessive shaking or displacement of the rotating shaft due to strong wind impacts. This ensures the stability of the damper, improves the wind resistance of the device, and allows it to maintain good adjustment performance even in strong wind environments.

Description

Technical Field

[0001] This utility model relates to the field of ventilation control technology, and in particular to a regulating damper for multiple air outlets. Background Technology

[0002] Multi-outlet regulating dampers are widely used in ventilation systems of industrial plants, commercial buildings, and agricultural facilities to regulate the flow rate and direction of airflow to meet the needs of different scenarios. Traditional regulating dampers usually use fixed baffles or manual operation to achieve airflow regulation, but these designs have some limitations in practical applications.

[0003] For example, while fixed baffles can guide airflow to some extent, they lack flexibility and cannot be adjusted according to real-time needs. Manually operated dampers, on the other hand, can provide some adjustment functions, but in multi-ventilation scenarios, due to the large number of baffles and their complex structure, manual adjustment is time-consuming and laborious, and prone to operational errors, thus affecting the overall efficiency and stability of the ventilation system. In addition, in strong wind environments, the baffles of traditional dampers are easily subjected to wind impacts, causing vibration or displacement, resulting in unstable adjustment effects or even structural damage.

[0004] Therefore, it is necessary to provide a new regulating damper for multiple air outlets to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a regulating damper for multiple air outlets.

[0006] The adjustable damper for multiple air outlets provided by this utility model includes: a support plate, a vertical plate, a wind force adjustment mechanism, and a wind-resistant mechanism. There are two support plates, and two symmetrically distributed vertical plates are fixedly connected between the two support plates. A wind force adjustment mechanism is provided between the two vertical plates. The wind force adjustment mechanism includes a rotating shaft, a wind baffle, a synchronization mechanism, and an adjustment handle. An adjustment groove is opened on the inner end face of the vertical plate. A wind baffle is fixedly connected to the outer surface of a plurality of evenly distributed rotating shafts rotatably connected between the two adjustment grooves. The plurality of rotating shafts are connected to each other through a synchronization mechanism. An adjustment handle is connected to the outer surface of the vertical plate. A wind-resistant mechanism is provided in the adjustment groove.

[0007] Preferably, the wind deflector is arc-shaped.

[0008] Preferably, the synchronization mechanism includes a chain and gears. Gears are fixedly connected to the outer sides of both ends of the rotating shaft, and multiple gears on the same side are connected by chain drive. The two ends of the rotating shaft located at the center pass through the inner walls of the two vertical plates and are fixedly connected to the adjustment handle.

[0009] Preferably, the wind-resistant mechanism includes an arc-shaped plate and a spring. The adjusting groove has multiple evenly distributed stabilizing grooves. Both sides of the stabilizing groove are connected to the arc-shaped plate by springs, and the rotating shaft is in contact with the arc-shaped plate.

[0010] Preferably, the arc-shaped plate is fixedly connected to the inner wall of the stabilizing groove by a telescopic rod.

[0011] Preferably, a magnet is fixedly connected to the bottom inner end face of the wind deflector.

[0012] Compared with related technologies, the regulating damper for multiple air outlets provided by this utility model has the following beneficial effects:

[0013] 1. This utility model achieves efficient adjustment of multiple air outlets by setting up a wind force adjustment mechanism. By adjusting the angle of the rotating shaft, the wind deflector can be rotated, thereby adjusting the air volume. The wind deflector is designed in an arc shape, which can effectively guide airflow, reduce wind resistance, and optimize airflow distribution. The arc design of the wind deflector also enhances the sealing performance of the damper, reduces air leakage, and improves the adjustment accuracy of the system. Furthermore, through the synchronization mechanism, multiple rotating shafts can rotate synchronously, ensuring that the wind deflectors are consistent during adjustment and avoiding uneven airflow caused by the improper adjustment of a single wind deflector. In addition, the two ends of the rotating shaft located in the center pass through the inner wall of the vertical plate and are fixedly connected to the adjustment handle. The operator only needs to rotate the adjustment handle to drive multiple wind deflectors to rotate synchronously through the synchronization mechanism, which greatly improves the adjustment efficiency and reduces the difficulty of operation.

[0014] This invention significantly improves the stability and durability of the damper under strong wind conditions by setting a wind-resistant mechanism in the regulating groove. The two sides of the regulating groove are connected to the arc plate by springs, allowing the arc plate to move freely along the direction of the spring. During the operation of the device, when the wind force is large and causes the rotating shaft to contact the arc plate, the arc plate provides a certain damping effect on the rotating shaft under the action of the spring, thereby preventing the rotating shaft from shaking or shifting excessively due to the impact of strong winds. This ensures the stability of the wind deflector, improves the wind resistance of the device, and enables it to maintain good regulating performance even in strong wind environments.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 2 The present invention provides an adjustable damper for multiple air outlets, which includes: a support plate 1, a vertical plate 3, a wind force adjustment mechanism and a wind-resistant mechanism.

[0021] Please refer to Figure 1 and 2 As shown, there are two support plates 1. Two symmetrically distributed vertical plates 3 are fixedly connected between the two support plates 1. A wind power adjustment mechanism is provided between the two vertical plates 3. The wind power adjustment mechanism includes a rotating shaft 7, a wind deflector 5, a synchronization mechanism, and an adjustment handle 8 (the adjustment handle 8 has a self-locking function, and in actual use, the adjustment handle can be replaced with a drive motor to achieve automatic airflow adjustment). An adjustment groove 2 is opened on the inner end face of the vertical plate 3. Multiple evenly distributed rotating shafts 7 are rotatably connected between the two adjustment grooves 2. The wind deflector 5 is fixedly connected to the outer surface of the rotating shaft 7, and the multiple rotating shafts 7 are connected to each other through the synchronization mechanism. The adjustment handle 8 is connected to the outer surface of the vertical plate 3. The wind deflector 5 is arc-shaped. The synchronization mechanism includes a chain 4 and a gear 6. The gear 6 is fixedly connected to the outer sides of both ends of the rotating shaft 7, and the multiple gears 6 on the same side are connected by the chain 4. The two ends of the rotating shaft 7 located in the center pass through the inner walls of the two vertical plates 3 respectively and are fixedly connected to the adjustment handle 8.

[0022] It should be noted that this utility model achieves efficient adjustment of multiple air outlets by setting up a wind force adjustment mechanism. By adjusting the angle of the rotating shaft 7, the wind deflector 5 can be rotated, thereby adjusting the air volume. The wind deflector 5 is designed in an arc shape, which can effectively guide airflow, reduce wind resistance, and optimize airflow distribution. The arc design of the wind deflector 5 also enhances the sealing performance of the damper, reduces air leakage, and improves the adjustment accuracy of the system. Moreover, through the synchronization mechanism, multiple rotating shafts 7 can rotate synchronously, ensuring that the wind deflectors 5 remain consistent during adjustment and avoiding uneven airflow caused by the improper adjustment of a single wind deflector. In addition, the two ends of the rotating shaft 7 located in the center pass through the inner wall of the vertical plate 3 and are fixedly connected to the adjustment handle 8. The operator only needs to rotate the adjustment handle 8 to drive multiple wind deflectors 5 to rotate synchronously through the synchronization mechanism, which greatly improves the adjustment efficiency and reduces the difficulty of operation.

[0023] The regulating groove 2 is equipped with a wind-resistant mechanism, which includes an arc plate 12 and a spring 11. Multiple evenly distributed stabilizing grooves 9 are opened in the regulating groove 2. The two sides of the stabilizing groove 9 are connected to the arc plate 12 by the spring 11. The rotating shaft 7 is in contact with the arc plate 12. The arc plate 12 and the inner wall of the stabilizing groove 9 are fixedly connected by a telescopic rod 13.

[0024] It should be noted that this utility model significantly improves the stability and durability of the damper under strong wind conditions by setting a wind-resistant mechanism in the adjusting groove 2. The two sides of the stabilizing groove 9 are respectively connected to the arc plate 12 by springs 11, so that the arc plate 12 can move freely in the direction of the springs 11. During the operation of the device, when the wind force is large and causes the rotating shaft 7 to contact the arc plate 12, the arc plate 12 provides a certain damping effect on the rotating shaft 7 under the action of the springs 11, thereby preventing the rotating shaft 7 from shaking or shifting excessively due to the impact of strong winds, ensuring the stability of the wind deflector 5, improving the wind resistance of the device, and enabling it to maintain good adjustment performance in strong wind environments. At the same time, the arc plate 12 is fixedly connected to the inner wall of the stabilizing groove 9 by the telescopic rod 13, which enhances the support strength and positional stability of the arc plate 12.

[0025] Through the design of this wind-resistant mechanism, this utility model achieves airflow regulation while possessing excellent wind resistance and structural stability. It not only improves the service life of the equipment under high wind speed conditions but also effectively reduces vibration and noise during operation, thereby meeting the usage requirements in complex environments.

[0026] The bottom inner end face of the wind deflector 5 is fixedly connected with a magnet to enhance the sealing performance and operational stability of the damper. When the wind deflector 5 is in the closed state, the magnet can attract adjacent metal parts, thereby forming an additional sealing force and effectively reducing air leakage.

[0027] The working principle of the regulating damper for multiple air outlets provided by this utility model is as follows:

[0028] This invention achieves airflow regulation and stability improvement of multi-vent dampers under complex wind speed conditions through the coordinated operation of wind force adjustment mechanism and wind resistance mechanism.

[0029] The damper is equipped with a wind force adjustment mechanism and a wind resistance mechanism through the adjustment groove 2 between the two vertical plates 3. The operator rotates the adjustment handle 8 to drive the rotating shaft 7 located in the center to rotate. The two ends of the rotating shaft 7 are connected to the synchronization mechanism through the gears 6 fixed on its outer side. The synchronization mechanism consists of a chain 4 and multiple gears 6. Multiple gears on the same side are driven by the chain to ensure the synchronous rotation of all rotating shafts 7, which in turn drives the wind deflector 5 to adjust its angle synchronously, changing the opening and closing degree of the air vent, thereby realizing the adjustment of air volume.

[0030] When strong winds impact the airflow during adjustment, the wind-resistant mechanism inside the device plays a crucial role. The wind-resistant mechanism is located inside the adjustment groove 2 and mainly consists of an arc plate 12, a spring 11, a stabilizing groove 9, and a telescopic rod 13. The rotating shaft 7 contacts the arc plate 12. Under strong wind conditions, the rotating shaft 7 drives the arc plate 12 to compress towards the spring 11. The rebound force generated by the spring 11 provides damping for the rotating shaft 7, thereby mitigating the impact of external forces on the wind deflector 5. This design ensures the stability of the wind deflector 5 and the rotating shaft 7 under strong wind conditions, preventing them from undergoing large displacements or swaying due to excessive wind force.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
