Claims

[Scope of claim for utility model registration] Duct 1 with built-in damper 2 and damper outer shaft 3
The damper inner shaft 2 and the damper outer shaft 3 are connected to each other via a link mechanism or other rotation transmission mechanism 4 that rotates by the same angle in opposite directions. 2 and an outer shaft 3, damper blades 5 and 6 which open and close at the same angle are fixed to each other. A rotation transmission mechanism 4 that rotates the damper inner shaft 2 and the damper outer shaft 3 by the same angle in opposite directions includes an operating arm 7 fixedly attached to the damper inner shaft 1 and a V pivoted in opposite directions to a pivot 8 on the duct 1. The type arm 9 is connected to the operating arm 7 by a connecting rod 10 so as to rotate in the opposite direction, and the other end of the V-shaped arm 9 and an outer shaft operating arm 11 fixed to the damper outer shaft 3 are connected to the V-shaped arm 9. The air conditioning damper device according to claim 1, which uses a link mechanism connected by a connecting rod 12 so as to rotate in the same direction as the Utility Model Registered Claim. One end of a V-shaped operating arm 7 fixed to the damper inner shaft 1 as a rotation transmission mechanism 4 for rotating the damper inner shaft 2 and the damper outer shaft 3 by the same angle in opposite directions is provided at an axially symmetrical position on the duct. A V-shaped arm 9 pivoted in the opposite direction to the pivot 8 of the operating arm 7 is connected by a connecting rod 10 so as to rotate in the opposite direction, and the other end of the V-shaped operating arm 7 is attached to the other pivot 8' in the same direction. It is connected to the pivoted guide arm 13 by a connecting rod 14, and further includes a V-shaped arm 9 of the pivot shaft 8, an outer shaft operating arm 11 of the damper outer shaft 3, and a guide arm 15 pivoted to the pivot shaft 8' in parallel. An air conditioning damper device according to claim 1, which uses a link mechanism connected by connecting rods 12.
