Description

Technical Field

[0001] This utility model relates to the field of ship cabin ventilation technology, specifically to a ship cabin ventilation regulating device. Background Technology

[0002] The cabin air conditioning ventilation adopts a pressure return air design. The fresh air supplied to the cabin creates positive pressure, then enters the cabin corridor through ventilation ducts, and finally returns to the air conditioning unit through return air ducts to form a cycle. Generally, ventilation ducts connect the corridor and the atmosphere to maintain air pressure balance.

[0003] The existing ventilation duct pressure regulating device has a baffle hinged inside the ventilation duct. The baffle is opened by wind pressure to allow exhaust. However, as the baffle opens and closes continuously, it will collide with the baffle, which can easily generate noise. At the same time, the ship will rock during the journey, and the baffle will swing open with the ship's rocking, which cannot play a good isolation role. Utility Model Content

A stop block 14 is fixedly disposed at one end of the reset rod 13 away from the movable frame 2. A first spring 15 is movably sleeved on the rod wall of the reset rod 13. The two ends of the first spring 15 are respectively fixedly connected to the corresponding stop block 14 and the fixed block 12. When the wind pressure decreases, the first spring 15 will push the stop block 14 to reset, which will in turn drive the movable frame 2 to reset.

[0028] In one possible implementation, the buffer mechanism includes a first gear 8, a second gear 6, and a rack 4. The two first gears 8 are disposed on the front and rear sides of the ventilation pipe 1. A first rotating rod 7 is fixedly sleeved in the middle of the first gear 8. One end of the first rotating rod 7 is rotatably connected to the outer wall of the ventilation pipe 1. The second gear 6 is meshed below the first gear 8. A second rotating rod 5 is fixedly sleeved in the middle of the second gear 6. One end of the second rotating rod 5 is rotatably connected to the outer wall of the ventilation pipe 1.
