Abstract
The utility model relates to a double slider scale without a sliding weight, whose scale sleeve is the inner bore perforated pillar shape. A scale beam can penetrate through and move in the scale sleeve. By altering the relative location of the scale beam and the scale sleeve and dispensing with being additionally provided with a sliding weight, the balance of the scale can be realized, and the weighing purpose can be achieved. Because double cursors are arranged, the double-cursor scale without a sliding weight is made to have large weighing ranges and high accuracy. Simultaneously, an adjusting hand wheel and a locking screw are arranged, the double-cursor scale without a sliding weight is made to have convenient and flexible use, small size and convenient carrying. The double-cursor scale without a sliding weight can be made into indicia scales, small-sized, medium-size and large-sized serial products.
Description
The utility model is a kind of double vernier balance without weight, is to belong to a kind of weighing apparatus.
Present existing steelyard is that the stone roller scale is arranged basically, and its volume is big, Heavy Weight, and inconvenience is carried.And the small spring scale, then weighting error is bigger.
The purpose of this utility model, it is little just to provide a kind of volume, in light weight, is easy to carry about with one, and weighs accurately the double vernier balance without weight that the weight of weighing is big.
Solution of the present utility model is such: scale cover (2) is the columnar shape that endoporus connects, and the interior hole shape of the shape of the arm beam of steelyard (1) and scale cover (2) adapts and the endoporus that inserts scale cover (2) can be done to run through mobile; Have breach (A, B) at the two ends of scale cover (2), (A, B) locates to be carved with vernier graduation at breach; Scale cover (2) is provided with control hand wheel (9), and the part of control hand wheel (9) is passed scale cover (2), is stuck in the wedge groove of the arm beam of steelyard (1), and lock-screw (8) passes scale cover (2) can block the arm beam of steelyard (1).
The utility model is owing to adopt said structure, the mobile arm beam of steelyard (1) just can change lever ratio in scale cover (2), reach balance and need not to be provided with sliding weight of steelyard, during use, the effect of breach (A, B) is such: when claiming that thing weight is big, the arm beam of steelyard (1) moves to the left side, and when the arm beam of steelyard (1) moves to breach (A) when can't see, weigh is read from an other vernier graduation of breach (B) and a weighing scale of the arm beam of steelyard (1).When claiming thing weight hour, the arm beam of steelyard (1) claims to the right, when breach (B) be can't see the arm beam of steelyard (1), weigh is read from the vernier graduation on breach (A) side and another weighing scale of the arm beam of steelyard (1), if breach (A, B) can both be seen the arm beam of steelyard (1), then can both read the weight of weighing from breach (A, B).When needing fine setting, can stir handwheel (9), the handwheel center can be promoted the arm beam of steelyard and be moved by pole (4) supporting, after lock-screw (8) is tightened, just alleged weight scale can be fixed, so that observation or prevent that the arm beam of steelyard from dropping out when carrying.
The utility model has the advantages that and adopt communicating structure and double vernier form, volume is little, and in light weight being easy to carry about with one weighed accurately, and the weight of weighing is big, operation with aim at very convenient.
Embodiment of the present utility model as shown in drawings.
Accompanying drawing is that portable small capacity double vernier does not have the structural representation that stone roller claims.
In the present embodiment, part (3) is a securing member, and part (4) is a pole, and part (5) is the lifting cord of steelyard, and part (6) is a knife, and part (7) is that scale colludes.Two control hand wheels (9) are separately positioned on the two ends of scale cover (2).
The utility model can be made into series of products such as weighing with a small steelyard scale, little shape scale and medium-and-large-sized scale.
Claims (4)
1, a kind of double vernier balance without weight, mainly comprise the arm beam of steelyard (1) and scale cover (2), it is characterized in that the columnar shape that scale cover (2) connects for endoporus, the interior hole shape of the shape of the arm beam of steelyard (1) and scale cover (2) adapts and the endoporus that inserts scale cover (2) can be done to run through mobile.
2, double vernier balance without weight according to claim 1 is characterized in that having breach (A, B) at the two ends of scale cover (2), and (A, B) locates to be carved with vernier graduation at breach.
3, double vernier balance without weight according to claim 2 is characterized in that scale cover (2) is provided with control hand wheel (9), and the part of control hand wheel (9) is passed scale cover (2), is stuck in the wedge groove of the arm beam of steelyard (1).
4, double vernier balance without weight according to claim 3 is characterized in that lock-screw (8) passes scale cover (2) and can block the arm beam of steelyard (1).
