Abstract
The utility model discloses a double-scaleplate weighing apparatus whose weighing lever is a double-scaleplate weighing lever. A main-scaleplate sliding poise is arranged on a main-scaleplate weighing lever; a vice-scaleplate sliding poise is arranged on the vice-scaleplate weighing lever; the two ends of the weighing levers of the main and the vice-scaleplates are integrative; the middle is retained with space. An emphasis knife, and a weighing hook are arranged at one end of the double-scaleplate weighing lever; a fulcrum knife and a hand-held ring are positioned at the inner side of the emphasis knife. The utility model has the advantages that the precision is high and is 20 times that of the existing steelyards; the main and the vice-sliding poises are arranged on the main and the vice-scaleplates; the defect that one weighing apparatus with two poises is fundamentally solved.
Description
The utility model belongs to scale and makes the field.
Background technology of the present utility model is: the present wood steelyard used of people, especially in the transaction of country fair, town and country, use with a long historyly in China's field of circulation, and have a large capacity and a wide range.Especially in recent years, several times change a social system, improve after the founding of the state,, do not break through, so because of the fundamentally not solution of some drawbacks from structure though many improvement are being arranged aspect workmanship, the metering performance.Its subject matter is:
(1), manufacturing accuracy is low, with the current price incompatibility.Existing wood steelyard (comprising the metal steelyard), its version has limited precision and can't improve at all, and its kilogram group steelyard precision is the highest can only to reach 20g.As 500 gram tealeaves, more than 30 yuan of price, that 50 gram (liang) just is worth more than 3 yuan, 5 grams (money) just are worth more than 3 jiaos, and now the wood steelyard of usefulness is that 10 kilograms scale is an example with maximum weighing, and its precision national regulation (minimum division value) is 20 grams (4 money), and the above deal of 20 grams does not just have asterism and represents so, just can not claim, give 19 to restrain (three money are many) the nearly monobasic of standing to lose and how also not know in other words less.
(2), asterism visitor master can not be with seeing.Client purchases 500 gram things, the thallium rope should be placed on 500 jinxs point place, and the owner of cargo often is placed on about 400 grams, and client also cannot see.
(3), a scale two thalliums.Many owners of cargo deal with the correct thallium of using when market is checked, what use when selling goods is little thallium.
(4), specification is many.Existing national regulation wood steelyard has 15 specifications, all makes troubles for the manufacturing, use.
Purpose of design of the present utility model is:
Design a kind of balance with double scale, asterism is not directly perceived in the solution prior art, and precision is low, drawbacks such as a scale two thalliums.
Design proposal of the present utility model:
(1), She Ji guiding theory." balance with double scale " must be accomplished:
1. improve precision.With 10 kilograms be example, precision must by 20 the gram bring up to 1 the gram;
2. the weighing indicating value wants the visitor main with seeing;
3. solve a scale two thallium problems;
4. simplify specification.15 specifications (25,50,200,250,500 grams by national regulation; 1,3,5,10,15,30,50,100,150,200 kilograms) be reduced to 3-4 specification.
5. should improve the accuracy of metering, reduce production costs again.
6. alleviate the labour intensity of weighing.Every scale can an attached tripod, and support is weighed, need not be portable when claiming thing, reduce labor intensity.
7. both be equipped with steelyard hook on the emphasing knife, the scale pan had also been arranged, the convenient use.
(2), structural principle.Emphasing knife of balance with double scale, a fulcrum pivot, its cutter point is variable.Fulcrum is between emphasing knife and force, so be first kind of lever.By the lever principle design, its formula is: WOA=POB promptly heavily takes advantage of heavy offset distance to equal power and takes advantage of power offset distance.
(3), organization plan: a kind of balance with double scale, the arm beam of steelyard (9) is the double scale arm beam of steelyard, pay and to be equipped with on the scale arm beam of steelyard (1) that to pay the two ends that main scale trip thallium (6), master, pair scale arm beam of steelyard are housed on (7) on a scale trip thallium (2), the main scale arm beam of steelyard be that space (3) is left in one, centre, emphasing knife is located at an end of the double scale arm beam of steelyard, and steelyard hook (5) is housed, fulcrum pivot is positioned at the inboard of emphasing knife, and handheld ring (4) is housed.Pay the scale arm beam of steelyard (1) and be provided with force (10), its unit is gram; The main scale arm beam of steelyard (7) is provided with force (8), and its unit is a kilogram, and initial force (8,10) main, that pay on the scale arm beam of steelyard is vertically corresponding.There is notch at each scale division value place of main scale on the main scale arm beam of steelyard (7); Force (8,10) main, that pay on the scale arm beam of steelyard (7,1) is the two sides groove.
In a word, its metering performance will reach the unification of stability that weighing apparatus should have, sensitivity, unchangeability, these four characteristics of correctness.
(4), using method.Balance with double scale, main scale claims integer, is the 1-10 kilogram, pays scale and claims decimal, is the 1-100 gram, two scales institute weighing sum is the quantity of purchase.Be placed in 1 kilogram of notch as main scale trip thallium, pay scale trip thallium and be placed on the 50 gram scale marks, two number sums are 1050 grams (2 jin 1 liang).
The utility model is compared with background technology, and the one, the precision height, precision is 1 gram, improves 20 times of precision than original wood steelyard; The 2nd, the arm beam of steelyard is the square type, and changing double scale into by simple lever is main scale and pair scale, and pair staff gauge reticle spacing is wide, and client easily sees clearly, and there is notch at each scale division value place of main scale, and the trip thallium is stuck in the groove, and the speculator can't be speculated; The 3rd, the trip thallium is contained on the scale, can not arbitrarily take off, and has fundamentally solved the drawback of a scale two thalliums; The 4th, simplified the specification of scale, practical.
