Abstract

The utility model discloses a novel platform scale. On the basis of the existing scale, a sliding weight is added, which causes a scale beam to be provided with a light weight and a heavy weight which can independently slide, and the scale beam is correspondingly changed. In this way, when the weight of the light weight is 1/10 weight of the heavy weight, the reading of the heavy weight is 1 liang each grid, and the reading of the light weight is 1 qian each grid. Due to the fact that the weight of the object is the summation of indication calibrations of the two sliding weights, which causes the weighing precision to be increased by an order of magnitude. Simultaneously, the light weight can also be used to balance the ' tare ' of the object when weighing, which causes the scale to be more practical and convenient. A new product whose accuracy and operation convenience are raised is obtained as long as the utility model makes a little alteration on the existing scale.

Description

Platform scale

At present in the city in the popular weighing apparatus, platform balance, platform scale use a lot.Platform balance is widely used in various retail shops.Platform scale uses wider, is used for fields such as building, industrial and mineral, rural area.The theory structure of these two kinds of scales is similarly, and all by the scale pan, leverage, the scale thallium of slip and the counterweight of some are formed.Indicate the weight of institute's scale object during weighing by the scale thallium that on the arm beam of steelyard, slides.When the weight of weight surpasses arm beam of steelyard full scale, be suspended from regard to the counterweight with fixed weight on the fixedly scale thallium of arm beam of steelyard end, at this moment the weight of weight is indicated weight and the slip scale thallium indication weight sum on the counterweight.

In existing platform, platform scale use, the inconvenience part is arranged.Such as platform balance take a liang as minimum scale.This is the discontented expensive commodity weighing requirement of full price value often.When resembling commodity such as white fungus, seafood, Chinese crude drug when dealing, can only estimate and read, very inconvenient.When and for example using platform, platform scale, often need together with container or the support weighing of containing weight.Resemble with dustpan and contain rice, contain seasoning matter, put one with long plank and choose large bamboo or wicker basket or the like with bowl.Traditional in this case way is to claim container weight one " tare weight " earlier.Mobile slip scale thallium adds the weight net weight then, is the gross weight that should claim; Perhaps claim to such an extent that bear in mind behind the tare weight, claim again to such an extent that gross weight deducts tare weight and then is net weight.Above weighing method generally need be estimated and reads twice, and poor accuracy, and in a large number frequently during weighing (such as purchase grain, sell coal, claim sandstone etc.), in the above plus-minus process, be easy to make mistakes is calculated and is unequal to also that it is numerous.

Purpose of the present invention provides a kind of novel platform, platform scale.This scale is compared with existing scale, have only very little change on the structure.But the precision of weighing weight weight has improved an order of magnitude, when weighing-appliance has the weight of two parts weight, can point out various weight weight simultaneously respectively simultaneously, promptly reads " tare weight " and " net weight " simultaneously.It is more accurate, convenient that platform, platform scale are used.

Below details of the present invention is done an explanation:

Fig. 1 is one of scheme of novel platform balance.Platform balance among the figure removes the arm beam of steelyard 3.Slip scale thallium 1 and 2 and existing platform balance difference, all the other structures do not have substantial change.The essence of this scheme is a slip scale thallium of existing platform balance have been changed into 2 (be generally one big, one little) arm beams of steelyard 3 widened, and big thallium 1 and little thallium 2 can independently slided on the slideway separately.When the scale on the arm beam of steelyard is all just the same to sliding thallium 1 and 2.If it also can be other ratio that the weight of little thallium 2 has only the 1/10(of big thallium 1), little thallium moved corresponding weight 1 money of lattice when then big thallium moved corresponding 1 liang of 1 lattice.(being the corresponding 50g of the every lattice of big thallium, the corresponding 5g of the every lattice of little thallium).

When big thallium 1 is separately mobile, if then Novel platform balance and existing platform balance do not have any difference to little thallium 2 motionless (as at section start).And when alleged weight weight is not integer.(for example weight is 1 jin of 5 two 4 money) then big thallium moves to lower approximate value (being 1 jin 5 liang in the example) and moves little thallium again and read decimal (4 money), namely in the weighing, claimed that thing weight is big or small thallium reading sum.When weighing has the weight of " tare weight ", then available little thallium weighs up earlier tare weight and fixing, moves big thallium again and gets final product to the net weight scale.When scale is placed with fixed bearing or container, utilize little thallium to make the new balance of weighing, then can remove each loaded down with trivial details calculating from.Simultaneously, owing at this moment need not read tare weight, so removed the single reading error from.In the occasion of the normal change of support (container) weight, (claim sandstone such as the construction site, supporting plank can because of the moist and weightening finish that is stained with mud), then can regularly smooth with little thallium, make weighing precision higher.

When we increase to the number of slip scale thallium more than 2, also similar functions can be arranged, but complex structure some.If when adopting a plurality of sliding thallium, the weight of each sliding thallium also can be identical and as described above different.Number and the weight of sliding thallium can be selected on demand.

Say at platform balance mainly that below its its structural principle and function are applicable to platform scale fully.The two difference only is that the weight of weighing varies in size, and does not have substantive difference.

Fig. 2 is the three-view diagram of the substantial portion of Fig. 1.The arm beam of steelyard 3 is made I-shaped, and its upper and lower bossing polishing forms the slideway of sliding thallium 1 and 2, and the middle part recess engraves scale (this scale and the difference of existing scale scale are very little as long as two thalliums all can make things convenient for reading) as shown.When sliding thallium 1 and 2 was positioned at starting point, scale was answered

balance.Screw

6 and 7 fixing sliding thalliums 1 and 2 are used on track.

Fig. 3 is another program of novel platform balance.Here consider the manufacturing assembly process process of sliding thallium 1 and 2, and two thalliums are made an end opening, and two thalliums are assembled on the slideway with nut 8 and 9 screw-ins.Corresponding therewith, it is arranged side by side that 3 of the arm beams of steelyard are made two guide rails of slotting at the middle part.Article two, the scale on the guide rail is still identically, and the weight ratio of two thalliums is also identical with last scheme.

Outstanding advantages of the present invention is to have obtained high-grade new product with minimum investment.Take scheme that Fig. 1 and Fig. 2 were lifted as example, the part of comparing change in this scheme with existing scale is: the arm beam of steelyard, scale thallium.The wherein manufacturing of the arm beam of steelyard and former technology and require the tooling device of identical employing constant, just machine work has increase man-hour slightly; The technological process of scale and equipment are also constant, only increase slightly man-hour.The change of scale thallium, but need little thallium of many systems, (shape is different from original thallium), so the totle drilling cost increase of new product seldom, estimate to be no more than a few percent, but its weighing precision has improved an order of magnitude, and the comfort level of use improves greatly, can become the generation new product of platform, platform scale.

The explanation of Fig. 1: be novel platform balance view.Except sliding thallium 1 and 2, outside the structure of the arm beam of steelyard 3 had been narrated with the effect front, 4 be the counterweight counterweight among the figure, and 5 is fixing scale thallium, and they are the same with the remaining part of platform balance, all do not have any difference with existing platform balance.The view that pound not shown in FIG. claims, its change conditions is identical with platform balance with effect.

The explanation of Fig. 2: Fig. 2 is a sliding thallium 1,2 among Fig. 1, the thin portion three-view diagram of the arm beam of steelyard 3.Sliding thallium 1 and 2 adopts T-shaped groove to cooperate with the arm beam of steelyard among the figure, in fact, also can adopt the groove of other shape, and for example straight trough adds and tightens screw and cooperate.

The explanation of Fig. 3: Fig. 3 faces and side view for another kind of scheme, and the arm beam of steelyard is divided into two among the figure, no longer relies on the T-shaped projection location on the arm beam of steelyard, so the arm beam of steelyard can be done thinlyyer than the scheme of Fig. 2, with economical with materials.Two guide rails of the arm beam of steelyard can be made an integral body, also can make back bolt, weldering, riveted joint respectively.Bolt can utilize existing production procedure and equipment better after adopting manufacturing respectively, and cost may be lower.
