Abstract

The utility model discloses a magnetic balance. The utility model comprises a balance body which is positioned on a chassis and a size stick which is engraved with scale indication marks. The utility model has the technical measures that the balance body is composed of an outer cylinder and an inner cylinder which is arranged in the outer cylinder and can float up and down, and the bottom of the outer cylinder and the bottom of the inner cylinder are provided with opposite magnets with the same polarity; the upper end of the inner cylinder is provided with an object holding disc, and the side wall of the lower end is provided with a guide finger which is matched with the size stick and is used for indicating scales; the side wall of the outer cylinder is provided with a notch which is distributed up and down, and the guide finger is penetrated from the notch. After an object is put on the object holding disc, the object holding disc sinks and floats downwards. Because the bottom of the outer cylinder and the bottom of the inner cylinder are provided with the opposite magnets with the same polarity, the opposite magnets are mutually excluded; the object is heavier, the repelling force becomes stronger, the weight corresponding to the scale which is indicated by the guide finger sliding down is heavier. Thus, the function of weighing the object weight can be implemented. The utility model has the advantages of simple structure, high precision and convenient operation.

Description

Magnetic balance

Technical field

The utility model relates to metering outfit, particularly a kind of magnetic balance.

Background technology

The float Steelgard that prior art has a kind of people of confession that the quality of object is weighed; Utilize law of buoyancy, scale body employing buoyancy aid and systems stabilisation, reading device structure combining mode are without sliding weight of steelyard, scale on the object, directly reading. easy to use, rapid, accurate, thus it is low to solve general weighing apparatus sensitivity, it is loaded down with trivial details that error reaches operation greatly, the problem that structure is numerous and jumbled.But this float Steelgard is made trouble, and a certain amount of material that buoyancy is provided must be arranged.

As the applying date is the Chinese utility model patent " portable multifunctional permanent magnetism scale " (patent No. is ZL92214726.4) on May 31st, 1992, a kind of portable multiple function permanent magnetism scale is disclosed, by the arm beam of steelyard, counterweight, lift heavy object point, portable with compositions such as forces, the counterweight of this permanent magnetism scale is that permanent magnetic material is made, the arm beam of steelyard is that the alloy of iron, cobalt, nickel magnetic metal is made, and carries when weighing thing, and counterweight can not come off.The similar steelyard; Increase the small machine that uses battery again, using increases cost, and is subjected to only measuring the restriction of smallclothes object.

Summary of the invention

Technical problem to be solved in the utility model is at above-mentioned deficiency, and provides simple in structure, precision height, easy to operate magnetic balance.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: magnetic balance, comprise scale body that is positioned on the chassis and the scale bar that is carved with calibration indicator sign will, the technical measures of taking comprise: the scale body is made up of urceolus and the inner core that is arranged in this urceolus and can fluctuate, and the polarity that urceolus, interior tube bottom respectively are equipped with in opposite directions is identical magnet; The inner core upper end is a dish bearing matter, and the lower end sidewall is provided with the pointer that is used for indicating graduation that matches with the scale bar; Outer tube side wall has the notch that distributes along up and down, and pointer is passed by this notch.

For optimizing technique scheme, the measure of being taked also comprises:

For ease of the less or lighter object of weighing, above-mentioned magnet is permanent magnet, and dish bearing matter is bowl-shape.

For ease of weighing bigger or heavier as the truck type objects, above-mentioned magnet is the electromagnet that hot-wire coil forms, dish bearing matter is a tabular.

Be control smoothness up and down, above-mentioned urceolus, inner diameter of steel flue are close, and inner diameter of steel flue is slightly less than the urceolus diameter.

For further location, make inner core fluctuate steadily, end cap is equipped with in above-mentioned urceolus upper end.

The utility model scale body is made up of urceolus and the inner core that is arranged in this urceolus and can fluctuate, and the polarity that urceolus, interior tube bottom respectively are equipped with in opposite directions is identical magnet; The inner core upper end is a dish bearing matter, and the lower end sidewall is provided with the pointer that is used for indicating graduation that matches with the scale bar; Outer tube side wall has the notch that distributes along up and down, and pointer is passed by this notch.Be to rise and fall downwards after dish bearing matter is put object, because of, the polarity that urceolus, interior tube bottom respectively are equipped with in opposite directions is identical magnet, repel mutually, and object is heavy more, and repulsive force is strong more, and the weight of the scale correspondence that the pointer downslide is indicated is heavy more; Realize the effect of weighing weight of object.It is simple in structure, and the precision height is easy to operate.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Structure of the present utility model is seen shown in the accompanying drawing 1.

Magnetic balance, comprise the scale bar 2 that is positioned at The One On The Chassis scale body and is carved with calibration indicator sign will, scale body 1 is made up of urceolus 3 and the inner core 4 that is arranged in this urceolus and can fluctuate, the polarity that respectively be equipped with in opposite directions urceolus 3, inner core 4 bottoms is identical magnet 5, the magnet 5a of concrete urceolus 3 bottoms and the magnet 5b of inner core 4 bottoms; The inner core upper end is dish bearing matter 4a, and the lower end sidewall is provided with the pointer that is used for indicating graduation 6 that matches with the scale bar; Outer tube side wall has the notch that distributes along up and down, and pointer is passed by this notch.

For ease of the less or lighter object of weighing, magnet 5 is permanent magnet, and dish bearing matter 4a is bowl-shape.For ease of weighing bigger or heavier as the truck type objects, magnet is the electromagnet that hot-wire coil forms, dish bearing matter is a tabular.Be control smoothness up and down, above-mentioned urceolus, inner diameter of steel flue are close, and inner diameter of steel flue is slightly less than the urceolus diameter.For further location, make inner core fluctuate steadily, end cap 7 is equipped with in above-mentioned urceolus upper end.

Be to rise and fall downwards after dish bearing matter is put object, the polarity that urceolus, interior tube bottom respectively are equipped with in opposite directions is identical magnet, repel mutually, and object is heavy more, and repulsive force is strong more, and the weight of the scale correspondence that the pointer downslide is indicated is heavy more; Realize the effect of weighing weight of object.It is simple in structure, and the precision height is easy to operate.
