도 4는 본 발명에 따른 광 디스크 턴테이블의 분리 사시도이고, 도 5는 본 발명의 결합 저면도이며, 도 6은 도 5의 B-B선 단면도이다.4 is an exploded perspective view of an optical disk turntable according to the present invention, FIG. 5 is a combined bottom view of the present invention, and FIG. 6 is a cross-sectional view taken along line B-B of FIG.

이를 참고하면, 광 디스크(D)(가상선으로 도시)가 안착되는 턴테이블 본체(10)의 상면 중앙에는 광 디스크의 내경을 안내하기 위한 클램프(12)가 돌출 형성된다.Referring to this, a clamp 12 for guiding the inner diameter of the optical disk protrudes from the center of the upper surface of the turntable main body 10 on which the optical disk D (shown in phantom) is seated.

클램프(12)의 중앙에는 스핀들모터의 모터축(M)(가상선으로 도시)에 결합되도록 결합공(12a)이 천공되고, 내부에는 저면으로 개구된 설치공간(12b)이 형성되며, 클램프의 외측 둘레에는 소정의 간격을 두고 다수의 조립공(12c)이 관통 형성된다.A coupling hole 12a is drilled in the center of the clamp 12 so as to be coupled to the motor shaft M (shown in phantom) of the spindle motor, and an installation space 12b opened in the bottom is formed inside the clamp 12. A plurality of assembly holes 12c are formed through the outer periphery at predetermined intervals.

이때, 조립공(12c)은 120°의 등간격을 두고 3군데에 형성하는 것이 바람직하다.At this time, the assembling hole 12c is preferably formed in three places at equal intervals of 120 degrees.

또한, 본체(10)의 설치공간(12b)의 테두리에는 조립공(12c)과 대응되는 부분에 각각 클립 받침편(14)이 내측 방향으로 돌출 형성되고, 클립 받침편(14)의 사이 중간부분에는 리브 받침편(16)이 내측 방향으로 돌출 형성된다.In addition, at the edge of the installation space 12b of the main body 10, the clip support pieces 14 are formed to protrude inwardly in portions corresponding to the assembly holes 12c, respectively, and in the middle portion between the clip support pieces 14; The rib support piece 16 protrudes inwardly.

여기에서, 클립 받침편(14)은 후술하는 클립(20)이 이탈되는 것을 방지하는 것이고, 리브 받침편(16)은 탄성리브(22)가 이탈되는 것을 방지하기 위한 것이다.Here, the clip support piece 14 is for preventing the clip 20 mentioned later from being detached, and the rib support piece 16 is for preventing the elastic rib 22 from leaving.

그리고, 본체(10)의 설치공간(12b)에는 다수의 탄성리브(22)에 의해 일체로 연결된 다수의 클립(20)이 삽입되어 대응되는 조립공(12c)을 통해 클램프의 외부로 돌출되도록 구성된다.In addition, a plurality of clips 20 integrally connected by a plurality of elastic ribs 22 are inserted into the installation space 12b of the main body 10 to protrude to the outside of the clamp through the corresponding assembly holes 12c. .

즉, 클립(20)은 3개가 120°의 등간격을 두고 배치되며, 각각은 탄성리브(22)의 단부에 연결된다.That is, three clips 20 are arranged at equal intervals of 120 °, each of which is connected to an end of the elastic rib 22.

탄성리브(22)는 단부에 연결된 클립(20)에 탄성력을 부여하기 위해 양단이 내측 방향으로 변형되게 탄성력을 갖도록 형성되는데, 그 형상은 도면에서와 같이 상방향으로 굽은 호의 형상에서 그 양단이 다시 라운드지면서 상방향으로 경사지게 휘어지게 형성된다.The elastic ribs 22 are formed to have elastic force so that both ends thereof are deformed inwardly in order to impart elastic force to the clip 20 connected to the ends thereof, and the shape thereof is again formed in the shape of an arc bent upward as shown in the drawing. It is rounded and curved to be inclined upward.

이제, 이와 같이 구성된 본 발명의 조립 및 작용 효과를 설명한다.Now, the assembly and action effects of the present invention thus constructed will be described.

먼저 탄성리브(22)에 의해 연결된 클립(20)을 본체(10)의 설치공간(12b)에 조립하려면, 탄성리브(22)를 잡고 안쪽으로 오므려서 클립(20)의 전체적인 직경이 축소되도록 한 다음, 각각의 클립(20)을 대응되는 조립공(12c)에 배치되도록 한 후, 오므렸던 힘을 제거하면 된다.First, in order to assemble the clip 20 connected by the elastic ribs 22 to the installation space 12b of the main body 10, the elastic ribs 22 are held and pulled inward so that the overall diameter of the clip 20 is reduced. Next, each clip 20 is to be arranged in the corresponding assembly hole (12c), and then it is enough to remove the pinched force.

그러면, 탄성리브(22)가 벌어지면서 클립(20)이 각각의 조립공(12c)에 삽입되어 클램프(12)의 외측 방향으로 돌출되면서 광디스크의 내경을 가압하게 된다.Then, as the elastic rib 22 is opened, the clip 20 is inserted into each of the assembly holes 12c to protrude in the outward direction of the clamp 12 to press the inner diameter of the optical disk.

이렇게 조립된 클립(20)은 탄성리브(22)에 의해 탄성력을 갖게 되며, 외부에서 클립(20)을 누르면 탄성리브(22)가 변형되면서 클립(20)이 안쪽으로 모아지는 방향으로 이동하였다가 누르던 힘을 제거하면 탄성리브(22)의 복원력에 의해 원래의 위치로 복구된다.The clip 20 thus assembled has elastic force by the elastic ribs 22, and when the clip 20 is pushed from the outside, the elastic ribs 22 deform and move in the direction in which the clips 20 are collected inwards. When the pressing force is removed, the restoring force of the elastic ribs 22 restores the original position.

이와 같이, 본 발명은 다수의 클립(20)을 한번에 조립할 수 있기 때문에 조립성이 우수하고, 따라서 작업능률이 향상되며 생산성이 증대하게 된다.As described above, the present invention is excellent in assemblability because a plurality of clips 20 can be assembled at one time, thereby improving work efficiency and increasing productivity.

또한, 다수의 클립(20)과 탄성리브(22)가 일체로 형성되어 있기 때문에 부품수가 현저하게 줄어들게 되며, 이로 인해 제품의 원가가 절감되므로 타제품과 비교할 때 원가 경쟁력을 갖게 된다.In addition, since the plurality of clips 20 and the elastic ribs 22 are integrally formed, the number of parts is remarkably reduced, and as a result, the cost of the product is reduced, so that the cost is competitive compared with other products.

또한, 본 발명은 다수의 클립이 한번에 조립이 되기 때문에 각각의 클립을 개별적으로 조립하는 종래의 제품에 비해 클립의 편차를 최소화할 수 있으며, 따라서 제품의 품질 안정화를 가져오게 된다.In addition, the present invention can minimize the deviation of the clip compared to the conventional product to assemble each clip individually because a plurality of clips are assembled at a time, thereby bringing a stabilization of the quality of the product.

또한, 턴테이블의 전체적인 구조가 종래에 비해 간단하기 때문에 전체적인크기로 축소시켜 콤팩트하게 디자인 할 수 있는 장점이 있다.In addition, since the overall structure of the turntable is simple compared to the prior art, there is an advantage that can be compactly reduced to the overall size.

이상에서와 같이, 본 발명은 다수의 클립이 탄성리브에 의해 일체로 연결되어 한번에 조립이 가능하기 때문에 조립 편차가 최소화되고, 조립성 및 생산성이 향상되며, 부품수가 줄어들기 때문에 원가가 절감되어 원가 경쟁력을 갖게 되는 효과가 있다.As described above, in the present invention, since a plurality of clips are integrally connected by elastic ribs to be assembled at one time, assembly variation is minimized, assembly and productivity are improved, and cost is reduced because the number of parts is reduced. It has the effect of being competitive.
