The slide rheostat is provided with the screw thread central rotating shaft, the upper and lower slide sheet on the traveling insulating slide seat can be moved by the rotation of the rotating wheel, when the rotating wheel rotates for a round, the scale rod moves for a unit inward or outward with the traveling insulating slide seat, and the upper and lower slide sheet also moves for a unit, and when the rotating wheel rotates for one scale (1/10 round), one coil is switched, the upper and lower slide sheet is moved to a corresponding resistance coil via the traveling insulating slide seat, thus the scale data on the scale rod and rotating wheel can be read so as to calculate a corresponding resistance value. The scaled spiral-adjustable slide rheostat can change a resistance value connected to a circuit conveniently and read and calculate the corresponding resistance value, is convenient in usage, and changes the defect that a conventional slide rheostat cannot carry out direct reading.
Description
Technical field
The utility model relates to a kind of slide rheostat, particularly a kind of spiral scalable slide rheostat with scale.
Background technology
Slide rheostat is one of device commonly used in the electricity; change resistance by the coil turn that changes place in circuit; its advantage is can continuous change to be connected into the resistance in the circuit; adjusting resistance is very convenient; but slide resistor does not mostly have scale usually; can not read the resistance in the circuit, in use bring some inconvenience.
The utility model content
The utility model provides the spiral adjustable slide rheostat of a kind of energy by the scale scale reading, to remedy the deficiencies in the prior art.
The adjustable slide rheostat of the utility model scale spiral comprises slide rheostat, mark post, move about insulation slide, formations such as slide plate, conductor slide rail, thread center's rotating shaft, intermediate value reticle, slide rail, runner, scale datum line, joint, supporting leg up and down.Wherein: described slide rheostat is provided with thread center's rotating shaft, one end of thread center's rotating shaft is equipped with the runner of band scale, the insulation slide that moves about is installed in thread center's rotating shaft, the insulation slide that moves about is fixed and is moved about on slide rail, described mark post is provided with scale, mark post one end is fixed on the insulation slide rail that moves about, the other end passes and is stuck on the scale datum line, described slide plate up and down is fixed on the insulation slide that moves about, runner whenever circles, mark post inwardly or outwards moves a unit with the insulation slide that moves about, slide plate also moves a unit thereupon up and down, the runner revolution moves a scale (1/10 week), the insulation slide that moves about makes up and down, and slide plate moves on the corresponding resistance coil, promptly switch a coil, the upper conductor slide rail of conductor slide rail links to each other with resistive conductor, the lower conductor slide rail links to each other with inside conductor, it is very narrow that slide plate is particularly gone up slide plate up and down, can only guarantee to contact with a circle coil at every turn, following slide plate links to each other with the lower conductor slide rail, when the insulation slide that moves about moved to the right side end points, the mark post read value was 0, and zero graduation is aimed at the intermediate value reticle on the runner.Rotating wheel, regulate slide rheostat to the state that needs, a certain scale on the runner is aimed at the intermediate value reticle at this moment, a certain scale on the mark post is aimed at the scale datum line, resistance number=(mark post reading * 10+ runner reading) * every circle resistive conductor length * resistivity/resistive conductor cross-sectional area can draw corresponding resistance.
Owing to adopted technique scheme, the beneficial effects of the utility model are: by the adjustable slide rheostat of the spiral of scale scale reading, can change the resistance value that is connected into circuit easily, no matter which position slide plate slides into to the rotating wheel dish, can read numerical value easily, calculate the resistance value that slide resistor is connected into circuit, easy to use, having changed traditional slide rheostat can not direct reading defective.
