Description

Portable steelyard

The utility model relates to a kind of steelyard that measures Item Weight.

No matter the utensil of metering Item Weight is steelyard or electronic scales, all is not easy to carry.Though spring balance is easy to carry, because its degree of accuracy is too low, so that all marking on the spring balance that has: can not use as measurement instrument.

On present country fair, the phenomenon ubiquity of giving short weight.Therefore whether enough people are when buying the article of valency by weight, always the misgivings institute article of buying weight.

The purpose of this utility model is exactly that a kind of steelyard that can stretch will be provided.Whether it can make people go out to buy vegetables or carry (can hang on the bicycle or be placed in the vegetable basket) when buying other article, give short weight so that check the article of buying at any time.

The purpose of this utility model be achieved in that with wireless device on telescopic antenna similar, adopt two metal sleeve and metal cylinders that proportion is bigger that diameter is different, its medium-small diameter sleeve pipe (hereinafter to be referred as small casing) can insert in the major diameter sleeve pipe (hereinafter to be referred as big sleeve pipe) and go, and right cylinder can insert in the small casing.Their threes not only play the arm beam of steelyard but also play sliding weight of steelyard.On small casing and right cylinder, all indicate the scale of expression weight of object.When without this scale, right cylinder and small casing together can be inserted in the big sleeve pipe, can shorten length like this, so that carry.When using this scale, can earlier small casing be pulled out gradually (annotate: right cylinder is motionless in small casing) from big sleeve pipe.After treating the steelyard balance,, just can read the weight of article,, then again right cylinder be pulled out from small casing gradually, until reaching balance if still can not balance after all pulling out according to the scale on the pairing small casing of big cannula tip.Just can read the weight of article according to the scale on the pairing right cylinder in small casing end this moment.

The utility model is because only need two sleeve pipes and a right cylinder, and all is to adopt general current material, so cost is lower.Easy to carry owing to going out again, so general family is willing to accept.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.Accompanying drawing is the synoptic diagram when extending the back use according to the portable steelyard that the utility model proposes.

Below in conjunction with details and the operating position of accompanying drawing detailed description according to the concrete device that the utility model proposes.

When claiming article with steelyard, article (8) can be hung on the steelyard hook (7), if the weight of article is less, then use portable the lifting cord of a steelyard (5); If the weight of article is bigger, then use portable the lifting cord of a steelyard (6), subsequently sleeve pipe (2) to be pulled out left gradually, right cylinder this moment (3) is motionless in sleeve pipe (2).After making the steelyard balance, according to the scale on the pairing sleeve pipe of end line (2) of sleeve pipe (1) left end, the weight that just can read alleged article.Still can not balance if sleeve pipe (2) is all pulled out the back steelyard, then again right cylinder (3) is pulled out from sleeve pipe (2) gradually, after making the steelyard balance, according to the scale on the pairing right cylinder of end line (3) of sleeve pipe (2) left end, the weight that just can read article.

After using up this scale, sleeve pipe (2) and right cylinder (3) together can be inserted in the sleeve pipe (1).

When sleeve pipe (2) was pulled out from sleeve pipe (1), four fingers such as available middle finger were held sleeve pipe (2), referred to promote projection (4) on the sleeve pipe (1) with big mother, extracted out from sleeve pipe (1) so that sleeve pipe (2) is very fast.The effect of projection (9) is identical therewith.

For preventing that sleeve pipe (1), sleeve pipe (2) and right cylinder (3) mutually disconnect, its structure is identical with telescopic antenna on the wireless device, is not described in detail in this.

Should be noted that: in (1) accompanying drawing be that numeral should not be arranged below calibrated, in order to say something, so it is marked.And the scale that only drawn among the figure for the sake of simplicity.(2) in order to increase the scope of weighing of steelyard, the two own weight of right cylinder (3) and sleeve pipe (2) wants enough big.Because they also play a part sliding weight of steelyard.After satisfying this requirement, also can adopt nonmetallic materials to make.

Claims (1)

1. A kind of civilian portable steelyard, this scale mainly is made up of sleeve pipe (1), sleeve pipe (2) and a right cylinder (3), it is characterized in that when the time without this scale, right cylinder (3) and sleeve pipe (2) are together inserted in the sleeve pipe (1), when using this scale, right cylinder (3) and sleeve pipe (2) can be pulled out from sleeve pipe (1) successively.
