Claims

[Claims for Utility Model Registration] 1. Two-layer pipes installed inside a building, etc., which are installed in most of the punched-out parts of a building wall, have multiple rows of vents in the front ventilation part, and are located at the rear of the front ventilation part. An outer frame having an outer peripheral frame and a flange, and a ventilation frame having lateral grooves for inserting into the central separation wall of the two-layer pipe in the upper and lower vertical portions of the circumferential wall and connected to the flange of the outer frame. In the ventilation louver, an appropriate number of circumferential holes are bored in the flange of the ventilation frame, and a plate piece that is slightly wider than the circumferential holes and has a female threaded hole in the center is inserted into the inner surface of the flange of the ventilation frame. A small bolt is inserted from the outside into a suitable number of small holes drilled in the flange of the outer frame, and the small bolt is inserted through the circumferential hole of the ventilation frame into the hole of the plate. The entire structure is constructed by screwing into a female screw hole, and by loosening the small bolt, the outer frame can be positioned in a predetermined direction regardless of the direction of inclination of the ventilation frame fitted into the tip of the double-layer pipe. A ventilation louver for double-layer pipes characterized by consisting of: 2 By bending the center of the plate piece inward and screwing in a small bolt, the outer frame body and the ventilation frame body are connected with each other with a spring force, and the outer frame body can be attached without loosening the machine screws. A ventilation louver for a double-layer pipe according to claim 1, which is fixedly held by being rotated in a predetermined position.
