Abstract

A steel steelyard is a steelyard for measuring object weight, comprising a heavy pole, a weight pole, a shaft, a weight, and a display disk. The heavy pole and the weight pole are straight poles, the connecting point of which has the shaft which is arranged on the display disk. The plane of the heavy pole and the weight pole is parallel to the display disc; the shaft is perpendicular to the display disc. The weight pole has the weight, and the display disc has a heavy indication scale. When a heavy is hang on the heavy pole, the heavy pole and the weight pole rotates a certain angle so as to keep a balance between the weight and the heavy, and meanwhile the numerical value on the display disk corresponding to the heavy pole or the weight pole is the weight of the heavy. The utility model has weighting precision, long-term use reliability, convenient use, intuition, simple structure, and low cost.

Description

A kind of Steel balance

Technical field:

The utility model belongs to the surveying instrument technical field, is a kind of scale of weighing weight of object.

Background technology:

At present, the scale of weighing commodity generally adopts latch bracket pan scale and electronic scales on the market, spring long fatiguability deformation service time of latch bracket pan scale, and it is inaccurate to weigh, electronic scales cost height, general pedlar is difficult for accepting, and also occurs misoperation sometimes.

Technology contents:

The technical problems to be solved in the utility model is to disclose a kind of long-term use can guarantee that weighing is accurate, and the low Steel balance of cost.

The technical solution of the utility model is to adopt weight bar, stone roller bar, rotating shaft, sliding weight of steelyard and display panel to constitute Steel balance, weight bar and stone roller bar are straight-bar, there is rotating shaft in intersection, rotating shaft is fixed on the display panel, weight bar is parallel with display panel with the plane that the stone roller bar constitutes, rotating shaft is vertical with display panel, hangs with sliding weight of steelyard on the stone roller bar, and the weight indicating graduation is arranged on the display panel.When hanging with weight on the weight bar, weight bar and stone roller bar all rotate to an angle, and to keep the balance of sliding weight of steelyard and weight, this moment, the numerical value of weight bar or stone roller bar and display panel indicating graduation corresponding position was weight of heavy.

Because being tangent, the anglec of rotation of weight of heavy variation and weight bar and stone roller bar changes, the non-equalization of display panel indicating graduation, claimed weight of heavy in order to show intuitively, between weight bar and stone roller bar, be equiped with an arc-shaped rack, a gradually open form gear is housed on the display panel, the axis of gear is fixed on the display panel, the engagement of rack and pinion tooth, pointer is housed on the gear, when weighing, by tooth bar, gear drive, pointer is corresponding with the display panel of even scale, and indication is claimed weight of heavy.

The utility model is weighed accurately, and long-term usability is reliable, easy to use, directly perceived, simple in structure, and cost is low.

Description of drawings:

Fig. 1 is the utility model synoptic diagram;

Fig. 2 is the utility model synoptic diagram that tooth bar, gear are arranged.

Embodiment:

The utility model is by weight bar 1, stone roller bar 2, rotating shaft 3, sliding weight of steelyard 4 and display panel 5 constitute, weight bar 1 and stone roller bar 2 are straight-bar, there is rotating shaft 3 in intersection, rotating shaft 3 is fixed on the display panel 5, weight bar 1 is parallel with display panel 5 with the plane that stone roller bar 2 constitutes, rotating shaft 3 is vertical with display panel 5, hang with sliding weight of steelyard 4 on the stone roller bar 2, the weight indicating graduation is arranged on the display panel 5, be equiped with an arc-shaped rack 6 between weight bar 1 and stone roller bar 2, a gradually open form gear 7 is housed on the display panel 5, the axis of gear 7 is fixed on the display panel 5, tooth bar 6 and the engagement of gear 7 teeth are equipped with pointer 8 on the gear 7.

Claims (2)

1, a kind of Steel balance, it is characterized in that: it constitutes Steel balance by weight bar, stone roller bar, rotating shaft, sliding weight of steelyard and display panel, weight bar and stone roller bar are straight-bar, there is rotating shaft in intersection, rotating shaft is fixed on the display panel, weight bar is parallel with display panel with the plane that the stone roller bar constitutes, and rotating shaft is vertical with display panel, hangs with sliding weight of steelyard on the stone roller bar.

2, Steel balance according to claim 1, it is characterized in that: be equiped with an arc-shaped rack between weight bar and the stone roller bar, a gradually open form gear is housed on the display panel, the axis of gear is fixed on the display panel, pointer is equipped with in the engagement of rack and pinion tooth on the gear.
