Abstract

The utility model relates to a wooden steelyard, which comprises a steelyard bar, supporting points, a lifting system, a steelyard hook, etc. The supporting point portions at the lifting system and the steelyard hook portions on the steelyard bar are all provided with rolling bearings; the supporting point portion on the steelyard hook is provided with a horizontal indicating needle; horizontal indicating scales are carved on the steelyard bar corresponding to the indicating needle; a tray is fixed at the tail of the steelyard bar; a counterweight on the steelyard bar can be replaced with a sliding poise. The wooden steelyard has good sensitivity, enlarged weighing ranges and convenient carrying, and is suitable for being used in people's daily life.

Description

Steelyard

The utility model relates to a kind of Steelyard, contain the arm beam of steelyard, fulcrum, carry be, steelyard hook etc.

In people's daily life, the metering of weight directly relates to huge numbers of families.Weighing apparatus accurately whether, the both sides' that directly affect one's business interests.At present, use scarcely standard of more wooden scale in both parties' transaction, and directly adopt knife to do the force at the fulcrum place, if the knife passivation at fulcrum place, then positive negative error can reach 1-3%, so sensitivity is poor, and the weighing range is fixed, and whether the level of the arm beam of steelyard can not accurately be judged.

The purpose of this utility model be provide for fear of above-mentioned the deficiencies in the prior art part a kind of fulcrum highly sensitive, can enlarge the weighing range, can indicate the Steelyard of arm beam of steelyard level.

The purpose of this utility model can realize by following measure:

A kind of Steelyard, contain the arm beam of steelyard, fulcrum, carry be, steelyard hook etc., carrying on the arm beam of steelyard is with the fulcrum place at steelyard hook place rolling bearing to be housed all; Horizontal pointer is equipped with at fulcrum place on steelyard hook, is carved with the reveal competence scale on the arm beam of steelyard of pointer correspondence, is fixed with pallet at the afterbody of the arm beam of steelyard; Sliding weight of steelyard on the arm beam of steelyard can replace with rider, can put into the counterweight of range extension in pallet.

The utility model has following advantage compared to existing technology:

1, the utility model is installed rolling bearing, the sensitivity when improving arm beam of steelyard weighing at the fulcrum place.

2, the utility model is fixed with pallet at the afterbody of the arm beam of steelyard, puts into counterweight in pallet, can enlarge the weighing range; And be placed with horizontal pointer at the steelyard hook place, can show the levelness of the arm beam of steelyard.

3, sliding weight of steelyard of the present utility model can replace with rider, and the metering indication is more accurate.

4, the utility model is in light weight, easy to carry.

Concrete structure of the present utility model is provided by the following drawings:

Fig. 1 is a structural representation of the present utility model

It is the horizontal pointer 7-of 6-rolling bearing 8-steelyard hook that 1-arm beam of steelyard 2-fulcrum 3-rider 4-pallet 5-carries

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1 embodiment is described in further detail:

With reference to Fig. 1, the arm beam of steelyard of Steelyard (1) is identical with the common arm beam of steelyard, and carrying on the arm beam of steelyard (1) is that the fulcrum (2) that (5) and steelyard hook (8) are located all is equipped with rolling bearing (7); Afterbody at the arm beam of steelyard (1) is fixed with pallet (4); In pallet (4), can put into the counterweight of range extension.Because the afterbody at the arm beam of steelyard (1) is fixed with pallet (4), thereby for the head overstriking of counterweight at the arm beam of steelyard (1); In addition, on the fulcrum (2) that steelyard hook (8) is located, be fixed with horizontal pointer (6), on the corresponding arm beam of steelyard of pointer (6) (1), be carved with horizontal indicating graduation; Sliding weight of steelyard on the arm beam of steelyard (1) can use rider (3) to replace.In addition, rolling bearing also can be housed at the fulcrum place of general platform scale and improve sensitivity.

Claims (2)

1, a kind of Steelyard, containing the arm beam of steelyard (1), fulcrum (2), carrying is (5), steelyard hook (8) etc., it is characterized in that carrying on the arm beam of steelyard (1) is that the fulcrum (2) that (5) and steelyard hook (8) are located locates all to be equipped with rolling bearing (7); Locate to be equipped with horizontal pointer (6) at the fulcrum (2) on the steelyard hook (8) and on the corresponding arm beam of steelyard (1) of pointer (6), be carved with the reveal competence scale, be fixed with pallet (4) at the afterbody of the arm beam of steelyard (1); Sliding weight of steelyard on the arm beam of steelyard (1) can use rider (3) to replace.

2, Steelyard as claimed in claim 1 is characterized in that can putting into the counterweight of range extension in pallet (4).
