Description
Technical field
The utility model relates to a kind of physical measurement techniques field, particularly relates to a kind of high precision balance.
Background technology
Balance, a kind of weighing apparatus.Prop up balance beam by fulcrum (axle) at the center of beam and form two arms, each arm is hung a dish, the object of known quality is put in one of them dish, put object under test in another dish, the deflection of pointer when not swinging and point to center scale be fixed on beam just indicates the quality of object under test.Balance is a kind of bascule.Balance is a kind of weighing apparatus, is the instrument weighing mass of object.It is made according to lever principle, and respectively have a shallow bid at the two ends of lever, counterweight is put in one end, and the other end puts the object that will claim, and pointer is equipped with in lever central authorities, and during the balance of two ends, the quality (weight) at two ends is equal.These reasons have been platitude concerning learning physical people.Modern balance, more and more accurate, more and more sensitiveer, kind also gets more and more.We know, have general utility balance, analytical balance, have macroanalytical balance, micro-analytical balance, semi-micro analytical balance, etc.Notice, balance is not just develop into this appearance today quickly, and it also has one section of development history.
The invention of balance very early.Abound with a kind of hydrophyte in The Nile, Egypt delta, the spitting image of the reed of the many water area growths of China, successively peeled off by its stem and be torn into thin slice, can write, this thing is called sudd.Paper in the word of many European countries develops from the Latin of sudd.The book of the cursive one-tenth of paper using is sudd book, and it becomes the important historical document of ancient egypt.The situation of the ancient Egypt that nowadays we know, particularly the historical development situation of science and technology, is all much derive from the record on sudd book.According to the record of sudd book, as far back as B.C. more than 1500 years, Egyptian just uses balance, and somebody says, this time is also wanted early, greatly before B.C. 5000 years.Although it is very coarse that the balance of ancient Egypt does, there is the profile of modern balance, become the blank of modern balance.It is inconvenient that current existing balance adds counterweight, easily rocks, fluctuation of service, cause measuring accuracy lower during measurement.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to operate, stable, and measuring accuracy is high, the convenient high precision balance adding counterweight.
For solving the problem, the utility model adopts following technical scheme:
A kind of high precision balance, comprise mask, feet, balance beam and hanger, described feet is located at mask both sides, described feet is provided with spiral pin, the convenient height regulating feet of spiral pin, mask can be kept to be horizontal level, described spiral pin and feet are rotationally connected, described balance beam is located at above mask, described balance beam is fixedly connected with mask, joist frame is provided with below described hanger, air damping cylinder and scale pan, air damping cylinder can make when measuring steady, improving measurement accuracy, measurement can be made fast convenient simultaneously, pallet is provided with below described scale pan, lifting knob is connected with below described pallet, described joist frame and balance beam are rotationally connected, described hanger is fixedly connected with joist frame, described scale pan is fixedly connected with hanger by air damping cylinder, pointer is provided with in the middle part of described joist frame, pointer can indicate whether to reach balance, projection screen is provided with below described pointer.
As preferably, described balance beam side is provided with circle code, and circle code conveniently adds on balance beam.
As preferably, described circle code side is provided with circle code index dish, can know inquiry test weight.
