본 고안은 구리스나 실리콘 오일과 같은 점성유체의 점성으로 각종 기기의 회동부분이나 미끄럼 동작부분이 급격히 회동하거나 미끄럼동작하는 것을 제동하는 회전댐퍼에 관한 것이다.The present invention relates to a rotary damper for braking the rotating or sliding operation of the rotating part or the sliding part of various devices due to the viscosity of viscous fluid such as grease or silicone oil.

회전댐퍼는, 카세트 뚜껑, 텔레비젼 뚜껑 및 비디오 테이프 레코더의 비디오 테이프 삽입구와 같은 각종 기기의 회동부분이나 미끄럼 동작부분이 급격히 회동하여 오동작을 일으키거나 회손되는 것을 방지하기 위해 주로 사용되고 있다.Rotating dampers are mainly used to prevent the rotating or sliding portions of various devices such as cassette lids, television lids, and video tape insertion openings of video tape recorders from suddenly rotating and causing malfunction or damage.

이와 같은 목적으로 사용되고 있는 회전댐퍼는 대부분이 구리스나 실리콘 오일과 같은 점성유체를 수용하는 원형의 하우징과 이 하우징에 억지 끼워맞춤 결합되어 점성유체의 누출을 방지함과 아울러 이 점성유체의 점성에 의해 제동되면서 회동하는 피동치차로 구성된다.Rotating dampers used for this purpose are mostly circular housings containing viscous fluids such as grease or silicone oil, and are forcibly fitted to the housings to prevent the leakage of viscous fluids and also due to the viscosity of the viscous fluids. It consists of driven gear that rotates while braking.

이같이 구성된 회전댐퍼는 피동치차가 점성유체의 점성에 의해 그 회동이 제동되므로 각종기기의 회동부분이나, 미끄럼동작부분이 급격히 회동하거나 미끄럼 동작하는 것을 억제하여 이 부분들이 훼손되는 것을 방지하여 줄 뿐만 아니라 정확한 회동동작과 미끄럼 동작토록 하므로서 오동작이 발생되는 것을 방지하여 준다.The rotary damper configured as described above can be prevented from being damaged by preventing the rotation of the rotating parts and sliding parts of the various devices by suddenly rotating or sliding the driven gears because the rotation of the driven brakes is caused by the viscosity of the viscous fluid. Accurate turning and sliding operation prevents malfunctions.

그러나, 이러한 종래의 회전댐퍼는 대부분이 시간이 경과할 수록 점성유체가 수용된 원형의 하우징과 피동치차와의 결합부위에서 점성유체가 누출되는 등의 단점이 있으며, 이로 인하여 제동력이 현저히 감소되어 그 본체의 기능을 수행하지 못하는 등의 문제점이 있었다.However, such a conventional rotary damper has the disadvantage that the viscous fluid is leaked from the coupling portion between the circular housing and the driven gear in which the viscous fluid is accommodated, and as a result, the braking force is significantly reduced due to the main body of the rotary damper. There was a problem such as not performing the function.

본 고안은 상술한 바와 같은 종래의 제반문제점을 해소 하고자 한 것으로, 본 고안에 따른 목적은 하우징에 수용된 점성유체가 피동치차와의 결합부위로 누출되는 것을 방지하여 정확한 제동력을 발휘하도록 한 회전댐퍼를 제공하는 데 있다.The present invention is to solve the conventional problems as described above, the object according to the present invention is to prevent the leakage of the viscous fluid contained in the housing to the coupling portion with the driven gear to provide a rotary damper to exert an accurate braking force To provide.

이하 본 고안에 따른 구성 및 작용효과르 첨부도면에 의해 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings and the configuration and effect according to the present invention as follows.

본 고안은 움직임이 일정하게 카세트 뚜껑이나, 텔레비젼 뚜껑 및 비디오 테이프 레코더의 테이프 삽입구와 같은 각종 기기의 회동부분이나 미끄럼 동작부분에 별도의 고정수단에 의해 고정되는 하우징에 피동치차를 결합하여 상기 하우징에 수용된 점성유체의 점성으로 제동하는 것에 있어서, 상기 하우징(11)의 후면에는 고정편(12)이 설치되며, 전면에 형성된 외벽(13)의 내측면 양단에는 체결돌기(13a)가 형성되어 있으며, 그 중앙에 축설된 고정축(14)의 후단부 외주면과 전면에는 각각 톱니형의 걸림홈(14a)(14b)들이 설치된 고정부(10)와; 상기 고정축(14)에 형성된 걸림홈(14a)(14b)에 끼워 결합되는 걸림돌기(21)(22)들이 내주면상에 설치되어 있으며 입구부에는 환형의 밀착테(23)가 형성된 캡(20)과; 상기 외벽(13)의 내측면 양단에 형성된 체결돌기(13a)에 결합되어 회동하는 걸림턱(31)이 선단 외주면에 형성되어 있고, 내부중앙에는 상기 캡(20)이 끼워 결합되게 입구부에 경사안내면(32a)이 형성된 삽입홈(32)이 외주면에는 피동치차(33)가 형성된 회동부(30)와; 상기 캡(20)이 끼워지는 삽입홈(32)에 수용되어 회동부(30)의 회동을 제동하는 점성유체(40)로 구성된다.The present invention consistently moves the coupled gear to the housing which is fixed by a separate fixing means to the rotating part or the sliding operation part of various devices such as a cassette lid, a TV lid, and a tape insertion port of a video tape recorder. In braking by the viscosity of the received viscous fluid, a fixing piece 12 is installed on the rear surface of the housing 11, and fastening protrusions 13a are formed at both ends of the inner side surface of the outer wall 13 formed on the front surface. A fixed portion 10 having serrated engaging grooves 14a and 14b respectively disposed on the outer circumferential surface and the front surface of the rear end of the fixed shaft 14 arranged in the center thereof; The locking protrusions 21 and 22 which are fitted into the locking grooves 14a and 14b formed on the fixed shaft 14 are installed on the inner circumferential surface thereof, and the cap 20 having the annular contact frame 23 formed at the entrance thereof. )and; A locking jaw 31 coupled to the locking projection 13a formed at both ends of the inner side surface of the outer wall 13 is formed on the outer circumferential surface of the distal end, and the inlet portion is inclined to engage the cap 20 at the inner center thereof. An insertion groove 32 having a guide surface 32a formed therein with a pivoting portion 30 formed thereon with a driven gear 33; The cap 20 is accommodated in the insertion groove 32 is fitted is composed of a viscous fluid 40 for braking the rotation of the rotating part (30).

상기 고정부(10)는 하우징(11)의 후면에 설치된 고정편(12) 카세트 뚜껑이나 텔레비젼 뚜껑 및 비디오테이프레코더의 테이프 삽입구와 같은 회동부분이나 미끄럼동작부분이 설치된 기기본체(도시없음)에 별도의 체결도구에 의해 결합설치된다.The fixing part 10 is separate from the main body of the device (not shown) provided with a rotating part or a sliding part such as a cassette lid or a TV lid and a tape inserting port of a video tape recorder installed on the rear of the housing 11. It is installed by means of fastening tools.

상기 캡(20)은 하우징(11) 전면에 축설된 고정축(14)에 끼워 결합되는 것으로 고정축(14)의 후단부 외주면과 전면에 각각 형성된 톱니형의 걸림홈(14a)(14b)들에 끼워지는 걸림돌기(21)(22)들이 원통형의 캡(20)의 입구부 내부면과 내면에 각각 +자형으로 설치되어 있다.The cap 20 is fitted to the fixed shaft 14 arranged on the front surface of the housing 11 and is coupled to the toothed engaging grooves 14a and 14b respectively formed on the outer circumferential surface and the rear end of the fixed shaft 14. Engaging protrusions 21 and 22 fitted in the inner side and the inner surface of the inlet portion of the cylindrical cap 20 are respectively installed in a + shape.

또한 캡(20)의 후면에는 요홈(24)이 형성되어 있다.In addition, a recess 24 is formed at the rear of the cap 20.

상기 회동부(30)는 하우징(11)의 전면에 설치된 외벽(13)의 내측면 양단에 각각 돌출형성된 체결돌기(13a)에 원형의 걸림턱(31)을 반강제적으로 끼워져 회동하는 것이다.The rotating part 30 rotates by inserting the circular locking jaw 31 semi-forcedly into the fastening protrusions 13a protruding from both ends of the inner side surface of the outer wall 13 installed on the front surface of the housing 11.

이때 피동치차(33)는 카세트 뚜껑이나 텔레비젼 뚜껑 및 비디오 테이프 레코더의 테이프 삽입구와 같은 각종 기기의 회동부분이나 미끄럼 동작부분에 형성되는 이동치차와 맞무려 지게 설치된다.At this time, the driven gear 33 is provided so as to cope with the moving gear formed in the rotational part or the sliding operation part of various apparatuses, such as a cassette lid, a TV lid, and a tape insertion opening of a video tape recorder.

또한 피동치차(33)의 내부에 형성된 삽입홈(32)에는 상기 캡(20)의 후면에 형성된 요홈(24)에 끼워지는 마찰축(34)을 축설하면 보다 효과적이다.In addition, the insertion groove 32 formed inside the driven gear 33 is more effective if the friction shaft 34 is fitted to the groove 24 formed in the rear of the cap 20.

이는 삽입홈(32)에 수용된 점성유체(40)의 접촉면적을 보다 넓게 하므로서 피동치차(33)의 제동을 확실하게 한다.This ensures braking of the driven gear 33 by making the contact area of the viscous fluid 40 accommodated in the insertion groove 32 more wide.

상기 점성유체(40)는 상기 캡(20)이 끼워지는 삽입홈(32)에 수용되어 피동치차(33)의 회동시 이를 제동하는 것으로, 구리스나 실리콘 오일과 같이 점성이 강한 유체를 사용한다.The viscous fluid 40 is accommodated in the insertion groove 32 into which the cap 20 is fitted to brake it when the driven gear 33 is rotated, and a viscous fluid such as grease or silicone oil is used.

이와 같이 된 본 고안은 전체적으로 원형의 하우징(11)전면에 축설된 고정축(14)에 캡(20)을 결합하여 고정시키고, 삽입홈(32)에 점성유체(40)를 수용시킨 상태로 회동부(30)를 상기 하우징(11)에 반강제적으로 결합시키면 상기 캡(20)의 외주면이 점성유체(40)와 접촉하면서 결합된다.The present invention as described above, the cap 20 is fixed to the fixed shaft 14 formed on the front surface of the circular housing 11 as a whole, and the viscous fluid 40 is accommodated in the insertion groove 32 to rotate the state. When the eastern portion 30 is forcibly coupled to the housing 11, the outer circumferential surface of the cap 20 is coupled while contacting the viscous fluid 40.

이때 캡(20)의 입구부 외주연에 형성된 밀착테(23)는 삽입홈(32)의 경사안내면(32a)에 밀착 접촉된다.At this time, the close contact frame 23 formed on the outer periphery of the inlet portion of the cap 20 is in close contact with the inclined guide surface 32a of the insertion groove 32.

따라서 상기 삽입홉(32)에 수용된 점성유체(40)는 장시간이 경과하여도 외부로 누출되는 등의 상황은 발생하지 않아 지속적인 제동력을 발휘할 수 있는 유용한 것이다.Therefore, the viscous fluid 40 accommodated in the insertion hop 32 is useful to exert a continuous braking force because a situation such as leakage to the outside does not occur even after a long time passes.
