The present invention relates to a dual dial tuning device capable of driving two tuning devices with one dial knob.

Tuning device is a device that selects a frequency of a radio or television receiver, and is generally rotatable by being connected to the outside of a home appliance by a handle.

The current trend is that the size of the entire product is oriented to reduce the size of the current electronics as well as to use the internal circuits for integrated circuits.

In accordance with the present invention, a tuning device is formed with a single handle on a multifunctional electronic device such as a radio television receiver and the like, and an object of the present invention is to enable a function of each item according to a selection switch.

In the conventional tuning device, the radio is the radio and the television is the television. The tuning wire is connected to the knob to select a frequency to be watched by varying the capacity of the variable capacitor. It was chosen.

Therefore, in home appliances that have two or more functions, such as radio and television, the tuning device for each product must be provided separately, so that the volume and weight of the home appliances are relatively increased, and thus the production cost is increased. The disadvantages of each other were not reduced.

Another conventional tuning device is a method of installing dual dials in one place by installing a frequency selection part, that is, a part of a home appliance such as a bar-icon in a straight line, but such a conventional dual dial is a dial having a different diameter. If the knob and the shaft are prepared separately and the tuning device of the radio is installed with the shaft and the handle of a large diameter cylinder, the tuning device of the TV is inserted so that it does not touch each other inside the shaft of the radio. It has been applied to the principle of forming smaller and mounted inside the radio dial. Accordingly, the dial knobs of each other rotate together when the desired frequency is selected for each function, and in some cases, the small dial knobs are buried in the external dial knobs, thereby failing to function properly.

In the present invention, in order to solve such a problem, two tuning wheels, that is, a frequency selection wheel of a radio and a TV, are arranged on one axis fixedly connected to the main body, and one of the wheels is fixed for a power source. Only the wheel that is not fixed as it is driven to be suitable for the reduction-oriented home appliance according to the installation of two tuning wheels on one axis. same.

The present invention is composed of a rotary shaft (1), the selection portion (2) and the wheel portion (3) roughly, the rotary shaft (1) is the front end is fitted to the product body (4), the end of the handle (5) Is installed.

In addition, the selector 2 is composed of a solenoid 6, a crank 7, and a selector switch 8, which are operated by a power source, and are fitted to the rotating shaft 1 to ring 9, 9 ', 9 ", 9 The wheel part 3 which is fastened by the "" is composed of the first wheel 10, the second wheel 11 and the wheel shaft (10 ', 11').

In the drawings, reference numeral 12 denotes a central axis, 13 a center point, 14 a first stopper, 15 a second stopper, 16 a spring, 17 a lever, 18 a wire, and 19 a barrican.

Therefore, when describing the operating state of the present invention as a state of combining the present invention separated as shown in FIG.

That is, after screwing the rotary shaft (1) to the main body (4). The ring 9 is fixedly mounted to the rotary shaft 1.

When the first wheel is fitted to the rotary shaft 1, the wheel shaft 10 'is fitted only to the ring 9, and in turn, the rings 9 and 9' are fitted to the wheel 10 and 11 from the rotary shaft 1 to the left and right. To prevent it from being moved.

Insert the wheels (10, 11) into the ring (9 ") and then rotate the knob (5) to the end of the rotary shaft (1) to complete the dual dial length tuning device, but the rotary shaft (1) and each wheel (10,11) Lubricant flows in between to slightly smooth the wheels (10, 111) fitted to the rotary shaft (1).

Accordingly, when the knob 5 is rotated, the shaft 1 rotates so that the first and second wheels 10 and 11 rotate together, but when the wheel is stopped from the outside, only the rotation shaft 1 can be turned.

In the above state, when the crank 7 connected to the solenoid 6 is fixedly rotatably installed at the center point 13, the first stopper 14 and the second stopper 15 of the crank 7 are respectively fixed. It is located in contact with the first wheel 10 and the second wheel 11 and the crank 7 is always in contact with the second wheel 11 by the force of the spring 16 to the second stopper 15. do.

In the present invention, if the first stopper 14 and the first wheel 10 are bonded to each other, that is, a state in which only the second wheel 11 is driven, the second wheel is stopped. The state in which only the first wheel 10 is driven is a radio selection tuning device.

The above is an example of FIG. 2, which shows the connection state between the wire 18 wound on the shafts 10 'and 11' and the barrican 19. When the selection switch 8 is operated in the radio position, the solenoid 6 By rotating the handle 5 to overcome the elasticity of the spring 16 and the lever 17 is pushed and the first stopper 14 and the first wheel 10 of the crank 7 is engaged by When rotating (1), only the second wheel 11 is driven to enable radio selection.

By using the present invention as described above, there is a margin to fully utilize the internal space of the product main body, and thus the cost is reduced, and thus a multifaceted effect such as reduced manufacturing process is expected.

Claims (1)

In a home appliance in which a dual tuning device is used, a wheel part 3 formed on the product body 4 and a selection part 2 operated by the solenoid 6 are provided, and the wheel part 3 is a wheel. A shaft 10 ', 11' formed with wheels 10, 11, rings 9, 9 ', 9 ", 9'" and a handle 5, wherein the selector 2 has a spring 16 ) And the crank (7) formed with the lever (17) and the first and second stoppers (14, 15), the lubricant is injected between the wheels (10, 11) fitted snugly to the rotating shaft (1) so that the solenoid ( 6) a dual dial tuning device characterized in that the wheel in contact with the crank (7) pivoting about the center point (13) is stopped.
