본 고안은 콘트롤 놉의 편실 보상장치에 관한 것으로, 전기전자제품 케이스 내의 회로기판에 설치되는 볼륨본체 회전축에 사방으로 걸림 돌기가 형성된 전달구를 끼워맞춤 고정되게 하고,The present invention relates to a single thread compensating device of the control knob, to fit and secure the transmission port is formed in all directions on the rotary shaft of the volume body installed on the circuit board in the electrical and electronics case,

콘트롤놉의 중공축에 맞춤 돌기가 형성된 탄성편을 형성하여 케이스의 축공 단턱에 탄성력 있게 고정시키고, 중공축의 첨단에 사방으로 형성된 걸림 요흠을 상기 전달구의 걸림돌기에 걸림 유동되게 조립시켜 콘트롤놉의 편심 회전을 충분히 보상할 수 있게 한 것이다.Elastomeric rotation of the control knob by forming an elastic piece with a projection formed on the hollow shaft of the control knob to elastically fix the axial hole step of the case, and assembling the locking grooves formed on all sides of the hollow shaft to the locking projection of the transmission port. It is enough to compensate.

종래 카셋트나 앰프에 사용되는 콘트롤놉을 조립함에 있어서는, 케이스에 형성된 관통공으로 볼륨본체의 회전축에 콘트롤놉을 끼워 맞춤시켜 콘트롤놉의 중공축과 볼륨본체의 회전축을 직접 조립되게 하였던 것으로, 조립에 있어, 부품의 치수공차와 조립과정에서 발생하는 오차에 의해 볼륨본체의 회전축과 케이스의 관통공과의 중심이 일치하지 않게 되어 콘트롤놉으 조립시에 편심이 되거나, 케이스의 관통공이 작을 경우에는 콘트롤놉이 회전될때 무리하게 접촉이 되어 제품의 신뢰성을 저하시켰던 것이다.In assembling a control knob used in a conventional cassette or amplifier, the control knob is fitted to the rotary shaft of the volume main body with a through hole formed in the case to directly assemble the hollow shaft of the control knob and the rotary shaft of the volume main body. Due to the dimensional tolerances of parts and errors in the assembly process, the center of rotation of the volume main body and the through hole of the case do not coincide with each other. When contacted by force, the reliability of the product was reduced.

본 고안은 상기의 결점을 개선하기 위하여, 사법으로 걸림돌기가 형성된 전달구를 볼륨본체 회전축의 고정부에 설치하여 케이스에 탄성력 있게 조립되는 콘트롤놉의 중공축 첨단에 형성된 걸림요흠으로 걸림유동되게 조립시켜 부품의 치수 오차나 조립시의 오차에 의해 편심이 발생되더라도 콘트롤놉이 흔들림이 없이 원할한 회전이 이루어지도록 하였으며,The present invention, in order to improve the above-mentioned drawbacks, by installing a transmission port formed with a locking projection by means of jujube in the fixed portion of the volume main body rotation shaft to assemble the locking fluid to the locking groove formed on the tip of the hollow shaft of the control knob that is elastically assembled to the case Even if eccentricity occurs due to the dimensional error of the part or the assembly error, the control knob can be smoothly rotated without shaking.

콘트롤놉의 안내리브에 의해 케이스의 전면에 콘트롤놉이 전체적으로 접촉됨이 없이 접촉 마찰을 적게 하여 콘트롤놉이 회전할 수 있도록 하였다.The guide ribs of the control knob allow the control knob to rotate by reducing contact friction without the entire contact of the control knob on the front of the case.

이를 첨부도면에 의해 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.

케이스(1)내에 설치되는 볼륨본체(2)의 회전축(3)에 콘트롤놉(4)이 끼워맞춤 되게 설치하는 것에 있어서, 외주의 사방으로 걸림돌기(5)가 형성된 전달구(6)를 형성하여, 케이스(1)내의 브라켓트(7)에 고정된 회로기판(8)에 설치되는 볼륨본체(2) 회전축(3)의 고정부(9)에 끼워맞춤 고정하고, 콘트롤놉(4)의 중공축(10)을 서로 대향되게 절취시켜 맞춤돌기(11)(11')를 형성시킨 탄성편(12)(12')을 형성하여, 케이스(1)의 축공단턱(13)에 끼워맞춤 조립되게하며, 중공축(10)의 천단에는 사방으로 걸림요흠(14)을 형성하여 상기 전달구(6)의 걸림돌기(5)에 끼워맞춤 되도록 하였으며,In the case where the control knob 4 is fitted to the rotary shaft 3 of the volume main body 2 installed in the case 1, a transmission port 6 having a locking protrusion 5 is formed on all sides of the outer periphery. To fit the fixing portion 9 of the volume main body 2 and the rotating shaft 3 installed on the circuit board 8 fixed to the bracket 7 in the case 1, and the hollow of the control knob 4 Elastic shafts 12 and 12 'are formed by cutting the shaft 10 opposite to each other to form the alignment protrusions 11 and 11', and fitting them to the shaft joint step 13 of the case 1. And, on the top end of the hollow shaft (10) was formed in all four corners 14 to be fitted to the engaging projection (5) of the transmission port (6),

그리고, 콘트롤놉(4)의 내측으로 중공측(10)의 외주면에 다수의 안내리브(15)를 형성하여 콘트롤놉(4)이 케이스(1)의 전면에 직접 접촉됨이 없이 케이스(1)전면환형 요홈(16)에 안내리보(15)가 접속회동되도게 하였다.In addition, a plurality of guide ribs 15 are formed on the outer circumferential surface of the hollow side 10 to the inside of the control knob 4 so that the control knob 4 is not directly in contact with the front surface of the case 1. The guide ribs 15 were connected to the front annular groove 16 in a rotational manner.

이와같이 된 본 고안의 작용효과를 상세히 설명하면, 케이스(1)의 브라켓트에 연결되는 회로기판(8)에 설치된 볼륨본체(2)의 회전축 (3) 고정부(9)에 사방으로 걸림돌기(5)가 돌출 성형된 전달구(6)를 끼워맞춤 고정한 후, 축공단턱(13)이 형성된 케이스(1)에 콘트롤놉(4)의 중공축(10) 탄성편(12)(12')을 오므리는 방향으로 눌러 삽입시키면 탄성편(12)(12')의 맞춤돌기 (11)에 의해 눌린 상태로 이동되며, 완전히 밀어 삽입된 상태에서는 케이스(1)의 축공단턱(13) 맞춤돌기(11)가 탄성력 있게 걸림 고정되는 것이고 이때, 중공축(10)의 첨단 사방으로 형성된 걸림요흠(14)이 전달구(6)의 걸림돌기(5)에 일치되도록삽입시침에 따라서 콘트롤놉(4)의 케이스(1)고정이 어려움 없이 이루어지는 것이다.When explaining the operation and effect of the present invention as described above in detail, the locking projection (5) in all directions to the rotating shaft (3) fixing part (9) of the volume body (2) installed on the circuit board (8) connected to the bracket of the case (1) After fitting and fixing the delivery port 6 protruding, the hollow shaft 10 of the control knob 4, the elastic piece 12, 12 'of the control knob (4) to the case (1) formed with the shaft joint step (13). Pressing in the direction of retracting is moved in the pressed state by the alignment projections 11 of the elastic pieces 12, 12 ', and in the fully pushed-in state, the alignment projections 13 of the shaft joint step 13 of the case 1 11) is elastically latched and fixed at this time, the control knob (4) in accordance with the insertion guide so that the locking groove (14) formed in the four sides of the hollow shaft (10) coincide with the locking projection (5) of the transmission port (6) The case (1) is fixed without difficulty.

그리고, 콘트롤놉(4) 내측의 중공축(10) 외주면에 형성된 안내리브(15)에 의하여는 콘트롤놉(4)이 케이스(1)의 전면에 직접 접촉됨이 없이되고, 이로 인하여는 케이스(1)와 콘트롤놉(4)의 접촉 마찰을 최대한으로 줄일수 있어 콘트롤놉(4)의 회전이 스므스하게 회전안내 되는 것이다.In addition, the guide ribs 15 formed on the outer circumferential surface of the hollow shaft 10 inside the control knob 4 do not allow the control knob 4 to directly contact the front surface of the case 1, whereby the case ( Contact friction between 1) and the control knob 4 can be reduced to the maximum, so that the rotation of the control knob 4 is smoothly guided.

또한, 전달구(6)의 걸림돌기(5)에 콘트롤놉(4) 중공축(10)의 걸림요흠(14)이 조립되게 함에 있어서도, 걸림돌기(5)와 걸림요흠(14)이 약간의 틈새를 두고 있어서, 부품 제작시의 오차나 조립 과정에서 오차가 발생하여 콘트롤놉(4)의 중공축(10)과 볼륨본체(2)의 회전축(3)과의 중심이 일치하지 않을 경우, 즉 편심이 발생할 경우에도 콘트롤놉이 정회전으로 원할하게 회전이 이루어지도록 하고 있는 것이다.In addition, even when the locking projections 14 of the control knob 4 and the hollow shaft 10 are assembled to the locking projections 5 of the transmission port 6, the locking projections 5 and the locking projections 14 are slightly reduced. In the case of a gap, an error occurs during manufacturing of the part or an assembly occurs so that the center of the hollow shaft 10 of the control knob 4 and the rotation shaft 3 of the volume body 2 do not coincide, that is, Even when eccentricity occurs, the control knob rotates smoothly.

이와같이 본 고안은 볼륨본체의 회전축에 전달구를 설치하여 콘트롤놉과 조립되게 하므로써 오차에 의한 편심이 발생되더라도 콘트롤놉이 원할하게 회전할 수 있도록 하고, 콘트롤놉이 중공축에 안내리브를 형성하여 콘트롤놉이 케이스 전면에 접촉됨이 없이 최소의 접촉 마찰로 스므스한 회전이 이루어질수 있도록 하여서 품질의 향상은 물론 수명 연장으로 제품의 신뢰성을 높일수 있는 것이다.As such, the present invention allows the control knob to rotate smoothly even when an eccentricity occurs due to an error caused by installing a transmission port on the rotating shaft of the volume main body, and the control knob forms a guide rib on the hollow shaft for control. The knob can be smoothly rotated with minimal contact friction without contacting the front of the case, improving the quality and extending the life of the product.
