Abstract
The utility model relates to a pocket complex-arm steelyard, which comprises two scale beams 1 and 2, a counterweight 3 which can be slid on the scale beam 1, a counterweight 4 which can be moved on the scale beam and a scale rack 9. Three fulcrums A, B and C are arranged on the scale beam 1, and the fulcrum A and one end of the scale rack 9, the fulcrum C and a connecting rod 5, the connecting rod 5 and a fulcrum an arranged on the scale beam 2 and the scale rack 9 and a fulcrum b arranged the scale beam 2 are all connected through movable hinges. Scale values are arranged on the scale beam 1, and a plurality of V-shaped grooves are arranged on the scale beam 2. The utility model has the advantages of light weight, small size and small division value, such as 10 grams or 5 grams. The pocket complex-arm steelyard is suitable for portability and calibration weight by people.
Description
The utility model relates to a kind of family expenses compound lever Pocket balance.
Common lever scale, bar is long, and stone roller heavily is not easy to carry, and the portable spring scale of certain weighing is arranged, and its scale division value is excessive again, should not make the usefulness of verification in the daily life.
The purpose of this utility model provides a kind of in light weight, and volume is little, is convenient to carry, and has the multiple stalk Pocket balance of suitable scale division value again, is convenient to correct in people's daily life the behavior of giving short weight.
The purpose of this utility model realizes in the following manner, and this Pocket balance utilization lever principle adopts the two counterweight structures of two arm beams of steelyard, and recently alleviates required counterweight weight with the suitable arm of force, has enough weighings and suitable scale division value again.
Advantage of the present utility model is that it is in light weight, and volume is little, approximately has only two box cigarette sizes, the hundreds of grammes per square metre, and scale division value less as 10 grams or 5 grams are very suitable for people and carry verification weight.
Embodiment of the present utility model is provided by accompanying drawing, describes structure of the present utility model and use in detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, this Pocket balance comprise two arm beams of steelyard 1 and 2, can be at the counterweight 3 that slides on the weighing lever 1, the counterweight 4 and the scale frame 9 that can on the arm beam of steelyard 2, move, scale frame 9 is a L shaped bar, there are three fulcrum A, B, C, fulcrum A to be connected by movable hinge on the arm beam of steelyard 1 with scale frame 9 one ends, fulcrum B and weight hook 8 is connected by movable hinge, fulcrum a passes through movable hinge and is connected on fulcrum C and connecting rod 5, connecting rod 5 and the arm beam of steelyard 2, and fulcrum b is connected by movable hinge with scale frame 9 other ends on the arm beam of steelyard 2.On the arm beam of steelyard 1 scale is arranged, scale division value is 10 grams (or 5 grams), several V-shaped grooves are arranged on the arm beam of steelyard 2, for example 8-10, counterweight 4 whenever moves a V-shaped groove distance on the arm beam of steelyard 2, represent definite value of alleged weight change, for example 1000 grams, 1500 grams or 2000 grams, this definite value is by when design defined, adjust nut 7 with balancing weight 6 and balance on the arm beam of steelyard 2,, handle 10 is arranged on the scale frame 9 to adjust balance, weight is hung on the hook 8, mobile counterweight 4 is on N or N-1 V-shaped groove, and mobile again counterweight 3 is horizontal the arm beam of steelyard 2, at this moment the scale value of indication on the arm beam of steelyard 2 adds that the scale value on the arm beam of steelyard 1 is alleged thing weight.Each V-shaped groove is to there being scale value on the arm beam of steelyard 2.
