Technical Field

[0001] This utility model relates to the field of door hinge air leakage control technology, and in particular to a hot air regulating door hinge air leakage control device. Background Technology

[0002] Hot air dampers are used to regulate airflow, but due to the frequent rotation of the door hinges and their contact with hot air, the seals at the door hinges are worn.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model discloses a device for controlling air leakage at the hinge of a hot air regulating door, comprising: a mounting frame 1, an mounting cavity 9 inside the mounting frame 1, the mounting cavity 9 penetrating the front and rear surfaces of the mounting frame 1, a mounting shell 3 inside the mounting cavity 9, the mounting shell 3 having no front and rear walls, a servo motor 4 fixedly connected inside the mounting shell 3, a rotating shaft 12 fixedly connected to the output end of the servo motor 4, a sealing sleeve 13 on the surface of the rotating shaft 12, the end of the rotating shaft 12 away from the servo motor 4 penetrating the mounting shell 3 and the mounting frame 1, and the end of the rotating shaft 12 away from the servo motor 4 being fixedly connected... A door panel 2 is fixedly connected. The above components cooperate with each other to form the basic structure of the hot air regulating door. A through opening 10 is provided on the surface of the mounting frame 1. The through opening 10 and the mounting frame 1 are connected to each other by the pivot 12. The through opening 10 improves the convenience of separating and disassembling the door panel 2. A rubber pad 16 is fixedly connected to the right surface of the mounting shell 3. The rubber pad 16 contacts the inner wall of the mounting cavity 9. The rubber pad 16 is used to increase the sealing effect of the mounting cavity 9. The diameter of the sealing sleeve 13 is larger than the width of the through opening 10. When using the device, the sealing sleeve 13 and the rubber pad 16 are in a compressed state.

[0024] Specifically, when using the device, the servo motor 4 directly drives the rotating shaft 12 to rotate, and the rotating shaft 12 synchronously drives the door panel 2 to rotate, thereby opening the door panel 2. When it is necessary to inspect the device and the door hinge, simply pull the mounting shell 3 forward. Due to the existence of the through opening 10, the rotating shaft 12 is provided with space to separate from the mounting frame 1. When resetting the mounting shell 3, the rubber pad 16 contacts the inner wall of the mounting cavity 9 during the process of the mounting shell 3 entering the mounting cavity 9, thereby sealing the through opening 10 and preventing hot air from entering the interior of the mounting cavity 9 through the through opening 10. The rubber pad 16 is in a static state and will not be affected by external forces, so it will not be easily damaged.

[0025] A sealing plate 5 is provided at the front end of the mounting shell 3. A connecting rod 6 is fixedly connected to the rear surface of the sealing plate 5. The rear end of the connecting rod 6 is inserted into the interior of the mounting shell 3. The sealing plate 5 is used to close the front end of the mounting shell 3. A fan 11 is fixedly connected to the rear surface of the sealing plate 5. The air outlet of the fan 11 is distributed in a front-rear opposite manner with the servo motor 4 and the rotating shaft 12. The fan 11 is used to restrict the flow direction of hot air inside the mounting shell 3. A limiting plate 8 is fixedly connected to the front surface of the sealing plate 5. When using the device, the rear end of the limiting plate 8 is engaged with the mounting frame 1. The upper and lower ends of the limiting plate 8 are rear-protruding structures. When using the device, the rear-protruding part of the limiting plate 8 engages with the mounting frame. 1. The limiting plate 8 is snapped together, and the rear protruding part of the limiting plate 8 contacts the surface of the mounting shell 3. The limiting plate 8 is used to increase the stability of the sealing plate 5 when it is in action, and to provide the mounting shell 3 with the condition of external force. The surface of the sealing plate 5 is fixedly connected with the lead tube 7. The rear end of the lead tube 7 penetrates the rear surface of the sealing plate 5. The lower end of the fan 11 is provided with a power cord socket 15. The upper surface of the lead tube 7 is provided with a lead wire through hole 14. The power cord socket 15 and the lead wire through hole 14 are distributed vertically opposite each other. The lead tube 7, the lead wire through hole 14, and the power cord socket 15 cooperate with each other to improve the convenience of the power cord of the traction fan 11 and the servo motor 4.

[0026] Specifically, when hot air needs to be discharged, fan 11 is turned on simultaneously. The lateral airflow of fan 11 and the backward flow of hot air work together to directly seal the hot air entering the mounting housing 3 under normal conditions. After the leaking air enters the mounting housing 3, the flow effect of the hot air inside the mounting housing 3 is reduced. Affected by the strong backward airflow of fan 11, the leaking air entering the mounting housing 3 directly contacts the main flow of hot air again through the rear end of the mounting housing 3. This avoids the leaking air entering the mounting housing 3 from damaging the servo motor 4 and the shaft 12. The power cables of the servo motor 4 and the fan 11 extend outward through the lead tube 7.

[0027] Working principle: After prolonged rotation, the sealing performance of the heat-controlled door decreases, causing the emitted hot air to leak into the mounting housing 3. At this time, the hot air entering the mounting housing 3 is directly blown out of the mounting housing 3 by the strong horizontal wind of the fan 11, thereby reducing and limiting the dispersion range of the leaked air. This allows the leaked hot air to mix again with the main exhaust hot air duct. When it is necessary to inspect the door hinge and the device, a pulling force is applied directly to the limit plate 8 to separate the mounting housing 3 from the mounting frame 1. At the same time, the door panel 2 is also separated from the mounting frame 1, allowing the air leakage control device, door hinge and related components to be removed.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
