Description

Potentiometer

Technical Field

The utility model relates to a potentiometre field, especially a take potentiometre of double-colored lamp.

Background

The potentiometer on the current market has the main functions:

1. the potentiometer used as a voltage divider is a continuously adjustable resistor, and when the knob or slide of the potentiometer is adjusted, the moving contact slides on the resistor body. At this time, an output voltage having a certain relationship with the applied voltage of the potentiometer and the rotation angle or stroke of the movable arm is obtained at the output end of the potentiometer.

2. When used as a rheostat potentiometer, the potentiometer is connected into two end devices, so that a smoothly and continuously variable resistance value can be obtained within the stroke range of the potentiometer.

3. Use as a current controller when the potentiometer is used as a current controller, one of the selected current outputs must be a sliding contact lead-out.

Chinese patent publication No. CN 209328633U discloses a potentiometer including a brush, a circuit board, a housing, a first sealing member and a second sealing member; the utility model discloses a motor, including shell, brush, circuit board, first perforation, first sealing member, second perforation, the shell one end is provided with first perforation, and the other end is provided with the second perforation, the brush is worn to establish to be fixed on the first perforation, the circuit board is fixed in the second perforation, first sealing member sets up on the first fenestrate inner wall, first sealing member cooperation the brush is sealed first perforation, the second sealing member sets up the circuit board is kept away from on the second perforation of first fenestrate one side, just second sealing member sealing connection is in on the fenestrate lateral wall of second. The whole potentiometer of the potentiometer is in a sealed state, so that the potentiometer is protected relatively comprehensively, and the stability of the potentiometer is improved.

However, such a potentiometer is rigid in shape and cannot meet the needs of users.

SUMMERY OF THE UTILITY MODEL

The utility model discloses be stiff to present potentiometre shape, can not satisfy the not enough of user's needs, provide a potentiometre, add a bicolor lamp in the middle of current potentiometre, make the product more pleasing to the eye.

The utility model discloses a realize its technical purpose and the technical scheme who adopts is: a potentiometer comprises a potentiometer body, wherein the potentiometer body is provided with a potentiometer seat, and a potentiometer handle which can change the resistance between functional pins of the potentiometer through shaking is arranged on the potentiometer seat; the potentiometer handle is a hollow rotating handle, and an LED lamp is arranged in the middle of the rotating handle.

In the utility model, a double-color lamp is added in the middle of the existing potentiometer, so that the product is more beautiful.

Further, in the above potentiometer: the LED lamp comprises three light-emitting diodes of red, green and blue, anodes of the three light-emitting diodes of red, green and blue are connected together to form an anode pin of the LED lamp, and cathodes of the three light-emitting diodes of red, green and blue form R, G, B three pins.

Further, in the above potentiometer: and the red, green and blue light-emitting diodes are sequentially lightened in the rotating process of the rotating handle.

Further, in the above potentiometer: the rotating handle is a section of transparent pipe sleeved on the LED lamp.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description

Embodiment 1, this embodiment is a potentiometer with an LED lamp, and a bicolor lamp is added in the middle of the existing potentiometer, so that the product is more beautiful, as shown in fig. 1 and 2, the potentiometer of this embodiment includes a potentiometer body, and the potentiometer body is a potentiometer in the prior art. The potentiometer body is provided with a potentiometer seat 5, at least three functional pins 4 and a fixing pin 3 for fixing the functional pins are led out of the potentiometer seat 5, and a potentiometer handle 2 for changing the resistance between the functional pins 4 of the potentiometer through shaking is arranged on the potentiometer seat 5; in this embodiment, the potentiometer handle 2 is a hollow rotary handle, and the LED lamp 1 is disposed in the middle of the rotary handle. Specifically, the potentiometer handle 2 of the present embodiment is a section of transparent pipe, and the LED lamp is sleeved in the transparent pipe, and in practice, the section of transparent pipe can also be used as a lampshade of the LED lamp. In the embodiment, the LED lamp 1 includes three types of red, green and blue LEDs, in the LED lamp 1, anodes of the three types of red, green and blue LEDs are connected together to form an anode pin of the LED lamp 1, and cathodes of the three types of red, green and blue LEDs form R, G, B three pins. In practice, the anode pin of the LED lamp 1 is connected to the anode of the power supply, and the R, G, B pins are respectively connected to the power supply ground through the control, when the power is applied, that is, the anode pin of the LED lamp 1 is connected to the anode of the power supply, and the control switch arranged between the R, G, B pins and the power supply is closed, the LED lamp 1 will generate corresponding light.

In this embodiment, in transparent twist grip, be provided with the control switch of LED lamp 1, when twist grip starts the rotation from the initial angle, at first control the switch closure between R pin and the power ground, LED lamp 1 glows red, when twist grip rotates to the position of setting for, the switch closure between G pin and the power ground, green lamp is bright this moment, also can control the red light to extinguish simultaneously, or control the red light and continue to light, when twist grip continues to rotate, rotate to the setting for the position, control the blue light and light, can control red light and green lamp and all extinguish this moment, also can make red light and green lamp continue to light, produce white light this moment.
