When the upper wing is put into the main body, the assembly direction is not fixed and the teeth are engaged so that the assembly is quick and accurate. It relates to a ventilation hole characterized in that the wing and the middle wing are folded on the lower wing to control the amount of air in such a way that they overlap and unfold.

In general, an air conditioning vent is installed on the ceiling or wall of a building and exchanges the air inside the building with the air outside to purify the air inside the building.

The ventilation holes have various sizes and types depending on the purpose of use, and for quick ventilation, intake and exhaust means such as fan blades that can forcibly intake and exhaust air are installed on one side of the ventilation holes, and the intake and exhaust means are forced. In some cases, a fan equipped with a driving device such as a motor that can be driven by a motor is installed.

In addition, since it is difficult to operate an air conditioning system according to personal preference in a place equipped with a centralized air conditioning system such as a large building, a small ventilation hole is installed and used on the ceiling or wall of a building.

The conventional ventilation port is connected to an air supply pipe through which external air is drawn in, exhausts the air supplied through the outlet located in the room to the room, and opens the opening/closing plate installed at the outlet to adjust the amount of air supplied to the room. Since the intake and exhaust of the incoming external air are uniformly formed, the amount of air injected into the room is adjusted by adjusting the opening degree of the opening/closing plate installed at the outlet. As the tolerance between the air and the amount of exhausted air increases, the air resistance increases and noise occurs. If the gap is widened, the opening and closing plate descends a lot from the open part, so the gap becomes larger and the view becomes unsightly.

In order to solve the above problems, Patent Registration No. 10-0970389 "ventilator for indoor air conditioning" has an air supply port 1b formed at the top of the cylindrical body 1a, and an external air supply pipe 2 supplied from the outside. This is connected and an opening 1c is formed at the lower end of the cylindrical body, an outlet is formed so that air introduced from the outside can be injected into the room, and a stopping protrusion 1e that is an annular enlarged part is formed on the outer periphery of the outlet, so that the ceiling plate 3 ) In close contact with the bottom surface, the pressure finger plate 4 is hinged on both sides of the outer wall of the cylindrical body 1a, and the tightening bolt 5 pushes the inside of the hinge part, and the outer end of the pressure finger plate 4 contacts the upper surface of the ceiling plate 3 A female screw pipe 6 is installed in the center of the cylindrical body 1a, connected to the inner surface of the cylindrical body and three support pieces 6a, and the opening and closing plate 7 that opens and closes the opening in the screw hole of the female screw pipe 6 As the screw rod 7a formed in the center is screwed together and the opening/closing plate 7 is raised and lowered, the outlet of the opening 1c is opened and closed to adjust the amount of air supplied to the cylindrical body to be injected into the room. In the ventilation hole (1), a blanking plate 800 having an injection vent 801 formed therein is installed in the air supply port 1b at the upper end of the cylindrical body 1a, and is laminated on the blanking plate 800 to inject an injection vent 801. By assembling the adjustment plate 802 that allows the size of the adjustment plate 802 to be adjusted with the fixing bolt 803 to change the size of the ventilation hole 801 and fix it, the variable adjustment portion 8 or the upper air supply port 1b of the cylindrical body 1a ) is inserted into the center of the injection vent (80a) to a certain standard by selectively installing an adjustment tool selected from among the disk-shaped adjustment tools 80 formed at the top of the cylindrical body (1a) of the ventilation hole The size of the injection vent (801) It is a configuration that can be adjusted according to the size of the room.

In the pre-registered invention ventilation hole, an adjustment plate for opening and closing the injection vent is located on the blanking plate having injection vents on both sides, and then a fixing bolt is inserted so that the adjustment plate is rotatable. It is a configuration for fastening bolts.

The blanking plate assembled to control the amount of air in the ventilation hole is assembled by inserting the fixing bolt while the adjustment plate is in close contact with one side and then tightening the fixing bolt to the opening and closing plate. If the pressure to pressurize the adjustment plate is too large, the rotation of the shielding plate is not smooth, so it is difficult to control the amount of air. It should be fixed at this adjusted position, but it is not possible to adjust the amount of air by moving arbitrarily, and there is a problem that the assembly process is complicated and cumbersome.

In addition, when the injection vent hole is opened and closed by the rotation of the shielding plate, there is a problem in that the fixing bolt is loosened in the process of rotating the protrusion formed on one side of the shielding plate by hand.
