본 고안의 카 오디오(CAR AUDIO)등에 사용되고 있는 로터리 스위치의 축에 끼워지는 손잡이 사이에 얇은 철판으로된 관체를 끼워서 손잡이가 빠지지 않도록한 스위치 손잡이 고정장치에 관한 것이다.The present invention relates to a switch knob fixing device which prevents the handle from being pulled out by inserting a thin steel tube between the handles fitted to the shaft of a rotary switch used in a car audio of the present invention.
종래에는 로터리 스위치 축과 손잡이의 결합되는 부분에 요철부를 형성하여 결합시켰던 것이 있었으나 이는 카 오디오등에 사용되고 있는 로터리 스위치와 같이 잡아당기고 돌리는 것에 있어서 오래 사용하면 결합부위가 마모되어 헐거워지므로 손잡이가 쉽게 빠지는 결점이 있었다.Conventionally, there was a combination of irregularities formed on the coupling part of the rotary switch shaft and the handle, but this is a drawback that the handle is easily pulled out because the coupling part wears and loosens when pulled and turned like a rotary switch used in car audio. There was this.
본 고안은 이러한 종래의 결점을 제거하기 위하여 로터리 스위치축에 얇은 철판으로된 관체를 스위치 축과 결합되는 손잡이 구멍에 끼워줌으로써 결합부위가 헐거워져 손잡이가 쉽게 빠지는 것을 방지하기 위한 것으로서 본 고안 장치를 첨부된 도면에 의거하여 구성 및 작용효과를 설명하면 다음과 같다.The present invention is designed to prevent the handle from being easily detached by loosening the coupling part by inserting a tube made of a thin iron plate on the rotary switch shaft to the switch shaft in order to eliminate the conventional drawback. Referring to the configuration and operation effects based on the drawings as follows.
제2도와 같이 로터리 스위치 축(1)과 결합되는 손잡이(2)의 구멍(3) 사이에 탄성관(4)을 끼우되, 탄성관(4)이 절개된 단부의 요철부(5,5')가 구멍(3) 내면으 돌기부 (3')에 맞물리고, 탄성관(4)의 주면(4')에 서로 대향되게 형성된 홈(6,6')에 구멍(3)의 돌출부(7,7')가 끼워져서 된 것이다.As shown in FIG. 2, the elastic tube 4 is inserted between the holes 3 of the handle 2 engaged with the rotary switch shaft 1, and the uneven portion 5, 5 'at the end where the elastic tube 4 is cut out. ) Is engaged with the projection 3 'on the inner surface of the hole 3, and the projection 7 of the hole 3 is formed in the grooves 6, 6' formed on the main surface 4 'of the elastic tube 4 so as to face each other. 7 ') is inserted.
미설명 부호 1′는 로터리 스위치 축(1)에 형성된 장흠이다.Reference numeral 1 'is a defect formed in the rotary switch shaft 1.
이와 같이 구성되는 본 고안 장치의 작용효과를 설명하며 다음과 같다.It describes the operation and effect of the device of the present invention configured as described above are as follows.
본 고안의 탄성관(4)은 얇은 철판으로 되어 있어서 탄력을 갖게 되는데 제2도와 같이 탄성관(4)의 절개부에 형성된 갈퀴모양의 요철부(5,5')가 구멍(3)에 형성된 돌기부(3')에 맞물려서 손잡이(2)가 빠지지 않도록 하고 또한 탄성관(4)의 외주면에 형성된 홈(6,6')과 구멍(3)에 형성된 돌출부(7,7')가 서로 맞물려 고정되므로 손잡이(2)는 더욱 빠지지 않게 고정되는 것이다.The elastic tube 4 of the present invention is made of a thin iron plate to have elasticity, and as shown in FIG. 2, a rake-shaped uneven portion 5, 5 ′ formed in the cutout of the elastic tube 4 is formed in the hole 3. The handle 2 is prevented from coming off by engaging the protrusion 3 ', and the grooves 6 and 6' formed on the outer circumferential surface of the elastic tube 4 and the protrusions 7 and 7 'formed in the hole 3 are engaged with each other and fixed. Since the handle (2) is to be fixed not to fall further.
이와 같은 상태에서 축(1) 외주면에 홈(6,6')의 뒷면이 탄력에 의해 밀착되어 고정되는데 이것은 홈(6)과 홈(6')의 간격은 축(1)의 직경보다 약간 작기때문이다. 이때문에 축(1) 외주면과 탄성관(4) 내면과의 사이에 틈이 생기게 되나 장홈(1')에 돌기부 (3')가 끼워져 있으므로 손잡이(2)는 요동하지 않는다.In this state, the back surface of the grooves 6 and 6 'is fixed to the outer circumferential surface of the shaft 1 by elasticity, and the distance between the grooves 6 and the grooves 6' is slightly smaller than the diameter of the shaft 1. Because. For this reason, a gap is formed between the outer peripheral surface of the shaft 1 and the inner surface of the elastic tube 4, but since the projection 3 'is fitted in the long groove 1', the handle 2 does not swing.
이상과 같이 본 고안 장치는 로터리 스위치 축(1)과 탄성관(4)이 완전 고정되고 또 탄성관(4)과 구멍(3)이 확실하게 고정되므로 손잡이를 당겨서 돌리는 조작을 반복하더라도 손잡이는 빠지지 않을뿐만 아니라 기계적으로 마모되는 부분이 없어 장시간 사용할 수 있게된 것이다.As described above, since the rotary switch shaft 1 and the elastic tube 4 are completely fixed and the elastic tube 4 and the hole 3 are firmly fixed as described above, the handle does not come out even if the operation of pulling and turning the handle is repeated. Not only that, there is no mechanical wear part, so it can be used for a long time.
