Abstract
The utility model relates to a double-pointer spring scale balance, which comprises a balance pan support frame, a rack bar, a master gear, a base plate, a small pointer and a big pointer. The utility model is characterized in that a dial is provided with the big pointer and the small pointer; the small pointer can be driven to rotate by the master gear; the master gear can drive a hollow gear and the big pointer which is arranged on the hollow gear to rotate by a slide gear; the master gear, the slide gear and the hollow gear are arranged according to corresponding differential ratio. The utility model has the advantages of precise read value and easy use. The double-pointer spring scale balance is helpful for discovering the cheat behavior by a balance, and can ensure fair dealing.
Description
Technical field
The utility model relates to the measurement instrument technical field, particularly a kind of two pointer spring scale scales that can improve measuring accuracy.
Background technology
Widely used in the market spring scale scale, all be that simple pointer shows the value of weighing, its structure as shown in Figure 1, comprise scale pan support 1, tooth bar 2, main drive gear 3 and little finger of toe pin 4, its transmission principle is, scale pan support 1 is subjected to drops and drives tooth bar 2 to move down when weighing, tooth bar 2 drives little finger of toe pin 4 by main drive gear 3 and clockwise rotates, and is example with 10 kilograms of common spring scale scales, and pointer rotates a circle, it always weighs is 10 kilograms, owing to be subjected to the restriction of dial diameters, its minimum calibrated dial is 50 grams, when weigh less than or during greater than 50 grams, just can not accurately show the value of reading, therefore cause the purchase and sale dispute easily.
Technical scheme
The purpose of this utility model provides a kind of value of reading two pointer spring scale scales accurate, easy to use.
The utility model is to realize like this, comprise scale pan support, tooth bar, main drive gear, bedplate, little pointer and big pointer, it is characterized in that dial plate is provided with big pointer and little pointer, driving the little finger of toe pin by main drive gear rotates, main drive gear drives hollow wheel gear by slide gear and the big pointer that is arranged on the hollow wheel gear rotates, be provided with by corresponding differential ratio between main drive gear, slide gear, the hollow wheel gear
The utility model has the advantages that the value of reading is accurate, easy to use, owing to be provided with by certain differential ratio between main drive gear, slide gear, the hollow wheel gear, the ratio of revolution of large and small pointer is 10: 1, so big pointer can demonstrate the precision of 5 grams, help finding behavior, guarantee utmost fair dealing with the scale cheating.
Description of drawings
Fig. 1 is the structural representation of existing simple pointer to property spring scale scale;
Fig. 2 is the structural representation of two pointer spring scale scales;
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Shown in Fig. 2-3, this pair pointer spring scale scale comprises scale pan support 1, tooth bar 2, main drive gear 3, bedplate 5, little finger of toe pin 4 and big pointer 8, dial plate is provided with big pointer 8 and little finger of toe pin 4, driving little finger of toe pin 4 by main drive gear 3 rotates, main drive gear 3 drives hollow wheel gears 7 by slide gear 6 and the big pointer 8 that is arranged on the hollow wheel gear 7 rotates, by corresponding differential than being provided with, wherein the scale division value of little finger of toe pin 4 is 50 grams between main drive gear 3, slide gear 6, the hollow wheel gear 7; The scale division value of big pointer 8 is 5 grams.
Claims (1)
1, a kind of pair of pointer spring scale scale, it comprises scale pan support, tooth bar, main drive gear, bedplate, little pointer and big pointer, it is characterized in that dial plate is provided with big pointer and little pointer, driving the little finger of toe pin by main drive gear rotates, main drive gear drives hollow wheel gear by slide gear and the big pointer that is arranged on the hollow wheel gear rotates, between main drive gear, slide gear, the hollow wheel gear by corresponding differential than being provided with.
