Abstract

The utility model relates to a portable telescopic steelyard, which is composed of a steelyard beam, a steelyard hook, a counterweight, a handle and a balance weight object. The portable telescopic steelyard is characterized in that the steelyard beam is elliptical and is three or more sections like the telescopic antenna of a TV; the steelyard beam can be elongated when used, and can be shrunk or inserted when carried. The counterweight is combined by a plurality of pieces; a calculator is arranged on the counterweight. The utility model has the advantages of convenient carrying, convenient calculation and higher accuracy than an ordinary steelyard, and is an ideal steelyard.

Description

Portable telescopic steelyard

The utility model belongs to a kind of weights and measures, a kind of steelyard of saying so further.

At present, though existing various steelyards mostly carry inconvenience, many inconveniences have been brought to the user.

Task of the present utility model is to design a kind of pull-rod balance, and this steelyard can be elongated when the arm beam of steelyard uses, and the arm beam of steelyard can shorten or whole stubble when carrying, and is with counter on the sliding weight of steelyard, can conveniently do accounts.

Task of the present utility model can realize by following proposal:

The utility model is made up of the arm beam of steelyard, steelyard hook, sliding weight of steelyard, handle and mass.The arm beam of steelyard is an ellipse garden shape, as the televisor telescopic antenna, is three sections or many sections, can elongate during use, can shrink when carrying, and the purpose of ellipse garden shape is that pole does not rotate during for weighing.Steelyard hook has the chain of company with the steelyard hook of existing steelyard on the steelyard hook, connect chain and hang on the accurate cutter by drawing frame, and accurate cutter is the triangle cylindricality.Sliding weight of steelyard is many and combines, the sliding weight of steelyard main body is two halves, integral body is rectangle, second half corresponding position of each half-sum is fluted, in order to put counter weight and when carrying the arm beam of steelyard put the arm beam of steelyard after shortening, counter weight has two or many, and the sliding weight of steelyard main body has on half the side pacifies counter, can be stuck sliding weight of steelyard main body two half-sum counters by a clamp of just tearing open.Handle is by the triangle tool post, and framework is installed on the arm beam of steelyard.Scale is arranged on the arm beam of steelyard, and the handle place is zero when making that weighing does not add sliding weight of steelyard, and arm beam of steelyard left end head can be gone up a mass, and mass can the garden.

In order to meet national standard, the utility model also can be made the arm beam of steelyard two pairs of handles, and with following two kinds of scales, sliding weight of steelyard is three-in-one, and does not add the pull-rod balance of counter weight above having on the arm beam of steelyard.

The utility model has the advantages that: can be elongated when the arm beam of steelyard uses, can shorten when carrying or stubble, be with counter on the sliding weight of steelyard, can conveniently do accounts, the weighing accuracy of this pull-rod balance is higher than common steelyard.

Below in conjunction with accompanying drawing the utility model is done detailed description further.

Structural drawing when Fig. 1 is weighing;

Fig. 2 is the outside drawing when carrying;

Fig. 3 is the profile rear view when carrying;

The figure that Fig. 4 is integrated for sliding weight of steelyard main body one half-sum counter;

Fig. 5 is counter weight A figure;

Fig. 6 is the figure that sliding weight of steelyard main body and counter are being integrated;

Fig. 7 is counter weight B figure;

Fig. 8 is the structural drawing that two handles do not add counter weight.

Shown in Fig. 1-8, the utility model is made up of the arm beam of steelyard (1), steelyard hook (6), sliding weight of steelyard, handle (2) and mass (15).The arm beam of steelyard (1) is an ellipse garden shape, as the televisor telescopic antenna, is three sections or many sections, can elongate during use, can shrink when carrying, and the purpose in ellipse garden is that pole does not rotate during for weighing.Steelyard hook (6) has the chain (5) of company with the steelyard hook of existing steelyard on the steelyard hook (6), connect chain (5) and hang over accurate cutter A(3 by drawing frame (4)) on, accurate cutter A(3) be the triangle cylindricality.Sliding weight of steelyard is many and combines, the sliding weight of steelyard main body is two halves, integral body is rectangle, second half corresponding position of each half-sum is put bar groove (12) and is put counter weight groove (13), be used to put counter weight A(8), counter weight B(14) arm beam of steelyard (1) is put the arm beam of steelyard (1) after shortening and when carrying, two halves sliding weight of steelyard main body respectively is sliding weight of steelyard main body A (11) and sliding weight of steelyard main body B(9), counter weight has two or many, sliding weight of steelyard main body (9), (11) last counter (10) on one one side is arranged, can be by a clamp of just tearing open sliding weight of steelyard main body (9), (11) and counter (10) be stuck.Handle (2) is installed on the arm beam of steelyard (1) by triangle tool post (7), framework.The arm beam of steelyard has scale on (1), and not adding sliding weight of steelyard handle (2) bar place scale when making not weighing is zero, and the arm beam of steelyard (1) left end head can be gone up a mass (15), and mass (15) can be justified.

In order to meet national standard, as shown in Figure 8, also can make two handles are arranged on the arm beam of steelyard, be handle (2) and handle B(16), top and following two kinds of scales are arranged on the arm beam of steelyard (1), the sliding weight of steelyard body is sliding weight of steelyard main body A (11), sliding weight of steelyard main body B(9) and counter (10) three-in-one, and do not add the pull-rod balance of counter weight, counter weight groove (13) also no longer needs certainly.

The arm beam of steelyard of the present utility model (1) is stainless steel or steel plated item.

Using method of the present utility model is fairly simple, holds and does not describe in detail.
