본 고안은 이중튜우닝 노브축의 구조에 관한 것이다.The present invention relates to a structure of a double tuning knob shaft.

튜우닝 노브는 수신기에서 공진회로의 공진주파수와 일치시키기 위하여 바리콘등의 용량을 가변시켜 동조점을 맞추는대 사용된다. 그리고 이 튜우닝 노브는 와이어에 권취되어 바리콘의 용량의 가변 및 주파수의 눈금을 표시할 수가 있는 것이나 튜우닝시에 아주 미세한 조정을 행하기가 어려운 것이었다.The tuning knob is used to adjust the tuning point by varying the capacity of the barricon etc. in order to match the resonance frequency of the resonance circuit in the receiver. The tuning knob was wound around the wire to display the variable capacity and scale of the variicon, but it was difficult to make very fine adjustments during tuning.

따라서 종래에도 튜우닝 노브에 미세조정 튜우닝 노브를 같이 구성한 이중튜우닝 노브축을 제공하여 미세조정 튜우닝 노브의 수회 회전수에 의하여 치차로 연결된 튜우닝 노브축이 회전하도록 하여 튜우닝시에 미세조정을 행할 수 있게 하였으나 미세조정을 위한 치차의 구성이 어려우며 세밀한 미세조정이 곤란한 것이었다.Therefore, conventionally, a tuning knob shaft in which a fine tuning tuning knob is configured in the tuning knob is provided so that the tuning knob shaft connected to the gear is rotated by the number of rotations of the tuning knob. However, it was difficult to construct the gear for fine adjustment and it was difficult to make fine adjustment.

본 고안은 이와 같은 점을 감안하여 튜우닝축의 유설공과 튜우닝축을 관통시킨 미세조정 튜우닝축의 유설구 사이에 볼베아링 및 점착성 구리스를 삽입시켜 미세조정 튜우닝축의 회전시 볼베아링에 의하여 튜우닝축이 회동하도록 하여 이중튜우닝축의 구성을 간단히 하고 미세조정을 원활히 할 수 있게 한 것으로 이를 첨부도면에 의하여 상술하면 다음과 같다.In view of the above, the present invention inserts a ball bearing and a viscous grease between the tongue hole of the tuning shaft and the tongue hole of the tuning shaft which penetrates the tuning shaft, so that the tuning shaft is rotated by the ball bearing during rotation of the tuning shaft. By rotating, the configuration of the double tuning shaft was simplified and the fine adjustment was made smoothly. This will be described in detail with reference to the accompanying drawings.

본 고안은 제1도에서와 같이 와이어(1)가 권취된 튜우닝축(2)의 하부를 다수개 천공시켜 유설공(3)을 형성하고 튜우닝축(2)의 내부에 관통된 미세조정 튜우닝축(4)의 하부에 유설구(7)를 구성시켜 튜우닝축(2)의 유설공(3)과 미세조정 튜우닝축(4)의 유설구(7) 사이에 볼베아링(5)(5') 및 점착성구리스(6)를 삽입시킨 것으로 제2도와 제3도에서와 같이 튜우닝노브(17)는 튜우닝축(2)의 상단에 고정하고 미세조정 튜우닝노브(18)는 미세조정 튜우닝축(4)의 상단에 고정시킨 것이며, 볼트(9)의 내공에 고정홈(12)을 형성하여 볼베아링(5)이 삽입된채 튜우닝축(2)이 회전할 수 있게 구성하고 기판(11)에서 이중 튜우닝축이 고정되게 볼트(9)에 넛트(10)를 결합 구성시킨 것이다. 도면중 미설명부호 13은 의사이다.The present invention, as shown in FIG. 1, drills a plurality of lower portions of the tuning shaft 2 on which the wire 1 is wound to form a snow hole 3, and fine tuning tuning shafts penetrated inside the tuning shaft 2 A ball bearing (5) (5 ') is formed between the tongue hole (3) of the tuning shaft (2) and the tongue hole (7) of the fine tuning tuning shaft (4) by constructing a tongue (7) at the lower part of (4). And the adhesive grease 6 is inserted. As shown in FIG. 2 and FIG. 3, the tuning knob 17 is fixed to the upper end of the tuning shaft 2, and the fine tuning tuning knob 18 is fine-tuned tuning shaft ( 4) is fixed to the upper end, the fixing groove 12 is formed in the inner hole of the bolt (9) is configured so that the tuning shaft (2) can be rotated while the ball bearing (5) is inserted in the substrate 11 The nut 10 is coupled to the bolt 9 so that the double tuning shaft is fixed. Reference numeral 13 in the drawings is a doctor.

그리고 점착성 구리스(6)는 회전보륨이나 로타리스위치의 축수부에 사용하고 있는 G330 구리스이다.And the adhesive grease 6 is G330 grease used for the bearing part of a rotating volume or a rotary switch.

이와 같이 구성된 본 고안은 제3도에서와 같이 튜우닝시에 튜우닝노브(17)로서 방송주파수를 동조시키기 위하여 회전시키면 기판(11)에 고정된 볼트(9)의 고정홈(12)에서 볼베아링(5)(5')이 유설되면서 튜우닝축(2)이 회전하게 되어 튜우닝축(2)에 권취된 와이어(1)가 도시되어 있지 아니한 바리콘의 가변 및 주파수의 지지눈금을 표시하여 튜우닝 여부를 파악할 수가 있는 것이다.The present invention configured as described above is rotated to tune the broadcasting frequency as the tuning knob 17 at the time of tuning as shown in FIG. 3 and is viewed in the fixing groove 12 of the bolt 9 fixed to the substrate 11. Tuning shaft 2 is rotated as bearings 5 and 5 'are rotated to display the variable and frequency support scales of the baricon not shown in the tuning shaft 2 and the tuning shaft is tuned. You can figure out whether or not.

또한 미세조정에 의한 튜우닝시에는 미세조정 튜우닝노브(18)를 회전시키면 미세조정 튜우닝축(4)이 회전하면서 점착성구리스(6)에 의한 응집력에 의해 볼베아링(5)(5')이 튜우닝축(2)의 유설공(3)과 미세조정 튜우닝축(4)의 유설구(7) 사이에서 유설되면서 점착성 구리스(6)의 응집력에 의해 튜우닝축(2)을 회전시키게 되어 튜우닝축(2)에 권취된 와이어(1)가 미세하게 움직이므로 튜우닝시에 정확한 미세조정을 행할수 있는 효과가 있는 것으로 본 고안은 미세조정시에 부하에 의한 손실없이 스므스하게 조정되어 제품의 품위를 높일 수가 있는 것이다.In addition, when tuning the fine tuning, the fine tuning tuning knob 18 is rotated so that the fine tuning tuning shaft 4 rotates, thereby causing the ball bearings 5 and 5 'to become cohesive by the cohesive grease 6. While remaining between the tongue hole 3 of the tuning shaft 2 and the tongue opening 7 of the fine tuning tuning shaft 4, the tuning shaft 2 is rotated by the cohesive force of the cohesive grease 6. Since the wire (1) wound in 2) moves finely, it has the effect of making precise fine adjustments during tuning. The present invention smoothly adjusts without loss of load during fine adjustments to improve product quality. There is a number.

즉, 정착성 구리스의 토우크치는 50회전 전후에 1g당 20에서 22cm 정도 회전하는 것으로, 미세조정 튜우닝축(4)의 회전력에 점착성 구리스(6)에 가해지면 볼베아링(5)(5')이 회전되면서 튜우닝축(2)과 마찰에의한 회전력을 부가하여 미세조정을 행할 수가 있는 것으로 회전볼륨이나 로타리스위치의 축수부에 사용되고 있는 구리스는 점착성이 강하기 때문에 내·외축에 별도로 밀봉을 시키지 않아도 액체가 흐를 우려가 전혀 없기 때문에 구조의 단순화를 기할 수가 있는 것이다.That is, the torque value of the fixable grease rotates about 20 to 22 cm per 1g before and after the 50th rotation. When the adhesive grease 6 is applied to the rotational force of the fine tuning tuning shaft 4, the ball bearings 5 and 5 'are rotated. This rotation allows the fine tuning to be carried out by adding a rotating force due to friction with the tuning shaft 2. Since the copper used for the rotating volume or the bearing part of the rotary switch has strong adhesiveness, it is not necessary to seal the inner and outer shafts separately. Since there is no risk of liquid flow, the structure can be simplified.

이상에서와 같이 본 고안은 미세조정을 할 수 있는 이중튜우닝축의 전달력을 액체와 볼베아링으로 행함으로서 별도의 전달장치 없이 정확한 미세조정을 행할 수 있는 것으로 이중튜우닝축에 의한 구조가 간단해지며 제품의 품위를 높일 수 있는 효과가 있는 것이다.As described above, the present invention is capable of precise fine adjustment without a separate delivery device by performing the transmission force of the double tuning shaft, which can be finely adjusted, with a liquid and a ball bearing, thereby simplifying the structure by the double tuning shaft. The effect is to improve the product's quality.
