이와같은 구성으로 이루어진 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made of such a configuration as follows.

도2 내지 도5에서와 같이, 익스텐션(400)은, 그 일단이 에어벤트(100)의 외부에 돌출되어 동작되어도 좋으며, 본 발명과 같이 일단에 나사산(400a)을 형성한후 그 일측에 나사산(440a)으로서 치합되는 노브(440)에 의해 동작되어도 동일한 효과를 가져온다.2 to 5, the extension 400, one end thereof may protrude outside the air vent 100, the thread 400a at one end after forming the thread 400a at one end as in the present invention The same effect is obtained even when operated by the knob 440 engaged as 440a.

이때, 상기 익스텐션(400)은, 상기 익스텐션(400)의 일측을 에어벤트(100)의 외측면 까지 연장시켜 이를 동작시키면 그 일측에 치합되는 별도의 노브에 의해 동작하지 않아도 된다.At this time, the extension 400, by extending one side of the extension 400 to the outer surface of the air vent 100 to operate it does not need to operate by a separate knob that is engaged to one side.

상기 익스텐션(400)은 그 일면이 제1힌지축(420)으로서 에어벤트(100)의 외측면에 연결되어 일단에 접촉되는 노브(440)의 회전력을 로드댐퍼(300)에 그대로 전달하게 된다.One side of the extension 400 is connected to the outer surface of the air vent 100 as the first hinge shaft 420 to transmit the rotational force of the knob 440 that is in contact with one end to the rod damper 300 as it is.

그리고, 상기 익스텐션(400)이 그 일단에 치합되는 노브(440)에 의해 회전되면 익스텐션(400)에 돌출되는 제2힌지축(430)으로서 연결되는 로드댐퍼(300)를 회전시키게 된다.Then, when the extension 400 is rotated by the knob 440 engaged to one end thereof, the rod damper 300 connected as the second hinge shaft 430 protruding from the extension 400 is rotated.

이때, 상기 제2힌지축(430)은 로드댐퍼(300)의 일측에 형성되는 가이드홈(310)에 삽입되어 그 내측면을 이동하면서 회전력을 전달하게 되고, 상기 로드댐퍼(300)가 회전되면 상기 로드댐퍼(300)가 결합되는 댐퍼(200)를 회전시켜 에어벤트(100)의 공기통로를 차단하게 된다.At this time, the second hinge shaft 430 is inserted into the guide groove 310 formed on one side of the rod damper 300 to transfer the rotational force while moving the inner surface, when the rod damper 300 is rotated By rotating the damper 200 to which the rod damper 300 is coupled, the air passage of the air vent 100 is blocked.

더하여, 상기 가이드홈(310)는 핀 고정수단(320)이 일체로 형성되어 댐퍼(200)의 차단시 공기압에 의한 틈새발생이 방지되고, 댐퍼(200)에 의한 정확한 공기의 차단이 가능하게 되어 신뢰성을 제공한다.In addition, the guide groove 310 is formed with the pin fixing means 320 integrally prevents the occurrence of gaps due to the air pressure when the damper 200 is blocked, it is possible to block the air accurately by the damper 200 Provides reliability

A second line 320b that is bent in a 90-degree direction so as to rotate smoothly, and a second line 320b and a second line 320b that serve as a stopper on one side of the second line 320b. It consists of a third line 320c that is bent at an angle.

상기와 같은 핀 고정수단(320)은, 익스텐션(400)의 이동거리가 일정이상이되면 로드댐퍼(300)를 회전시키고, 상기 회전이 완료되면 역회전이 방지토록 되어 공기의 유동력에 의해 댐퍼의 들뜸이 방지된다.As described above, the pin fixing means 320 rotates the rod damper 300 when the movement distance of the extension 400 is greater than or equal to a predetermined distance, and prevents reverse rotation when the rotation is completed. Lifting is prevented.

그리고, 상기 로드댐퍼(300)는, 삼각형상으로 형성되어 2개의 꼭지점 부분에 위치토록 ㄴ자형상의 가이드홈(310)이 설치되며, 나머지 하나의 꼭지점 부에 댐퍼(200)의 중앙부가 고정되어 댐퍼(200)의 동작을 원활하게 수행하게 되는 것이다.In addition, the rod damper 300 is formed in a triangular shape, the N-shaped guide groove 310 is installed to be located at the two vertex portions, the central portion of the damper 200 is fixed to the other vertex portion damper The operation of 200 will be performed smoothly.

이와 같이 본 발명의 에어벤트의 댐퍼 개폐장치에 의하면, 댐퍼 동작에 따른 신뢰성을 향상시키도록 하고, 외부 요인에 의한 댐퍼의 움직임을 방지토록 하며, 별도의 부품 추가없이 댐퍼의 개폐상태를 유지하도록 하는 효과가 있는 것이다.Thus, according to the damper opening and closing device of the air vent of the present invention, to improve the reliability according to the damper operation, to prevent the damper movement due to external factors, and to maintain the open and closed state of the damper without adding additional parts It works.
