Abstract
The utility model discloses a double pointer spring scale, which is a spring scale driven by rack gears and gears. The kilogram and the kilogram scores of a dial are respectively marked by the scale; a scale mechanism is provided with a kilogram gear, a kilogram mating gear, a kilogram scores gear, and a kilogram scores mating gear. The utility model adopts the double-stage gear drive. The double pointer can respectively indicate the kilogram reading number and kilogram scores reading number. The utility model has the characteristics of compact structure, convenient installation, low cost, and convenient use.
Description
The utility model relates to a kind of spring balance with tooth bar, gear drive, particularly a kind of pair of pointer spring balance.
The spring balance of Shi Yonging is the one-level gear drive in the market, spring gravitate generation linear extension drive tooth bar moves when weighing, and rack drives and its meshed gears rotate, and indicate weight by the pointer that is fixed on the gear shaft on scale, owing to have only root pointer indication weight, make and reading error takes place the reading inconvenience of weighing easily, moreover, the gear-driven spring balance of existing one-level, spring scale counter scale particularly, volume is big, carries inconvenience.
The purpose of this utility model will provide a kind of volume little, portable, easy to use exactly, and the accuracy of reading of weighing has two pointer spring balances that two-stage is indicated.
The purpose of this utility model is achieved in that a kind of pair of pointer spring balance, by scale body 1, index dial 15, pointer, weighing plate 3, weighing spring 2 and include tooth bar 4, the weigher structure that constitutes with the driving gear 11 of tooth bar 4 engagement constitutes, it is characterized in that the kilogram on the index dial 15, the kilogram mark carries out scale respectively, pointer has kilogram pointer 14 and kilogram mark pointer 13, the weigher structure is by kilogram gear 10, kilogram mating gear 8, kilogram mark gear 12, kilogram mark mating gear 9, tooth bar back-moving spring 5 and precision regulating spring 6 are formed, kilogram mating gear 8 and kilogram mark mating gear 9 are fixed on the same axis, adopt splined between driving gear 11 and the kilogram gear 10,12 of kilogram mark gears are a tubular shaft, sky is enclosed within on 10 of kilogram gears, kilogram pointer 14 is fixed on 10 of kilogram gears, kilogram mark pointer 13 is fixed on 12 of kilogram mark gears, the moving circle of kilogram mark pointer 13 revolution on index dial 15, kilogram pointer 14 rotates a kilogram scale, tooth bar back-moving spring 5 one ends are connected with weighing plate 3, the other end is connected with tooth bar 4, precision regulating spring 6 one ends are fixed on the scale body 1, and the other end is connected with weighing plate 3.
The utility model is because employing has the two-stage gear drive, kilogram, kilogram mark divide the another name degree, institute is so that weighing is indicated, the accuracy of reading of weighing, and the difficult reading error that takes place, again because a kilogram mark gear shaft sky is enclosed within on kilogram gear shaft, and institute is so that its structure is compact more, thereby scale body volume is reduced, be easy to carry about with one, easy to use.Advantages such as the utility model also has simple in structure, and is easy for installation, cheap, suitable.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model weigher structure.
Fig. 3 is the utility model index dial synoptic diagram.
Among the figure, 1, the scale body, 2, weighing spring, 3, weighing plate, 4, tooth bar, 5, the tooth bar back-moving spring, 6, precision regulating spring, 7, the hook of weighing, 8, the kilogram mating gear, 9, kilogram mark mating gear, 10, the kilogram gear, 11, driving gear, 12, kilogram mark gear, 13, kilogram mark pointer, 14, the kilogram pointer, 15, index dial.
A kind of pair of pointer spring balance formed by scale body 1, index dial 15, pointer, weighing plate 3, weighing spring 2, tooth bar 4 with the weigher structure that the driving gear 11 of tooth bar 4 engagements constitutes.Kilogram on the index dial 15, the kilogram mark carries out scale respectively, pointer has kilogram pointer 14 and kilogram mark pointer 13, the weigher structure is by kilogram gear 10, kilogram mating gear 8, the kilogram mark number of teeth 12, kilogram mark mating gear 9, tooth bar back-moving spring 5 and precision regulating spring 6 are formed, kilogram mating gear 8 and kilogram mark mating gear 9 are fixed on the same axis, adopt splined between driving gear 14 and the kilogram gear 10,12 of kilogram mark gears are a tubular shaft, sky is enclosed within on 10 of kilogram gears, kilogram pointer 14 is fixed on 10 of kilogram gears, kilogram mark pointer 13 is fixed on 12 of kilogram mark gears, tooth bar back-moving spring 5 one ends are connected with weighing plate 3, the other end is connected with tooth bar 4, precision regulating spring 6 one ends are fixed on the scale body 1, and the other end is connected with weighing plate 3.
When hanging weight on the hook 7 of weighing, weighing spring 2 produces linear extension and drives tooth bar 4 displacements under action of gravity, and then tooth bar 4 drives and the driving gear 11 of its engagement, because driving gear 14 and kilogram gear 10 link with spline, so kilogram gear 10 also rotates simultaneously, and the kilogram mating gear 8 of drive and its engagement rotates, and kilogram mark mating gear 9 is fixed on the same axis with kilogram mating gear 8, rotates so kilogram mark ground gear 9 rotates and drive kilogram mark gear 12 simultaneously.When weighing when reaching, tooth bar 4 stops displacement, and each gear also stops operating simultaneously, and on index dial 15 read a kilogram number by kilogram pointer 14 this moment, and kilogram mark pointer 13 is read a kilogram mark.
When from weighing hook 7 when taking off weight, the 4 reverse displacements of weighing spring 2 reset strap carry-over bars, and driving gear 11 backward rotation of drive and tooth bar 4 engagements, kilogram gear 10 is reverse turn simultaneously, and drives kilogram mating gear 8 backward rotation, and kilogram mark mating gear 9 is backward rotation simultaneously, drive kilogram mark gear 12 backward rotation, when tooth bar 4 stopped displacement, each gear also stopped operating, and this moment, kilogram pointer 14 was all got back to zero-bit with a kilogram mark pointer 13.
