Abstract
The utility model relates to a weighing apparatus, particularly a digital dial weighing apparatus, comprising a lever gear mechanism, a force transmission mechanism and a display part. The utility model is characterized in that a force transmission plate is provided with a rack which is meshed with a pinion gear on the lever gear; the lever gear is meshed with a central gear with a pointer; the force transmission plate is provided with a regulation spring; a bearing piece which is connected with the force transmission plate is provided with a dial disc which is matched with the pointer; a digital display window which corresponds to the lever gear. When gravity is exerted on the bearing piece, the force transmission plate is moved downwards, the lever gear and the central gear are rotated by the pinion gear, and the weight is displayed in the form of digit and graduate. The utility model has the advantages of compact structure, high degree, large measuring range and low cost.
Description
The utility model relates to a kind of weighing apparatus, specifically is the Digital-indicating graduated disk scale.
China's steelyard in thousand can not adapt to the requirement of modernization life, owing to also do not have to replace fully its launch, so, for the moment also not superseded fully.Though existing electronic scales is good, but price is too high, repair rate big (reaching 30%); Seat formula spring scale scale or platform scale are too heavy, and inconvenience is carried, and price is not low yet; Though the portable hand scale of Chu Xianing is more convenient and cheap in the market, range is few, and low precision does not reach national measurement standard, can only family expenses, can not replace existing steelyard.
The purpose of this utility model just provides a kind of Digital-indicating graduated disk scale, and it is big to have a range, the precision height, make simple, compact conformation, the characteristics that cost is low.
The technical solution of the utility model is: comprise lever and gear wheel mechanism, force transmission mechanism and display part, wherein design has force transmitting board, tooth bar is arranged on force transmitting board, be meshed with the pinion wheel on the lever and gear wheel, lever and gear wheel meshes with the central gear of band pointer, on force transmitting board, be connected with supporting part, be provided with the index dial that cooperates with pointer, the digital displaying window corresponding with lever and gear wheel.
According to technique scheme, the design concept of the present utility model and the course of work are: apply external force on supporting part, force transmitting board is moved downward, pinion rotation on the rack drives lever and gear wheel on it, thereby lever and gear wheel is rotated, like this, not only utilize lever principle with the amplification range of weighing, and become rectilinear motion and be circular motion, also utilize the rotation of lever and gear wheel to show weight simultaneously.Owing to be engaged with central gear with lever and gear wheel, lever and gear wheel drives central gear rotates pointer, like this, just can on lever and gear wheel, put on such as the kilogram number with the form of numeral, show the kilogram number by digital displaying window, at count accurately (remainder) that utilizes on the index dial below the pointer indication kilogram.Adopt different lever and gear wheels to cooperate, just can produce the scale of different journey amounts, to satisfy different needs with the number of teeth of central gear.The precision that the regulation and control spring can be regulated metering is to guarantee the error in the wide range.
The utility model is a two-side display structure, promptly symmetry is equipped with two toothed rack on force transmitting board, be meshed with pinion wheel on the lever and gear wheel of the left and right sides respectively, lever and gear wheel lays respectively at the both sides, front and back of force transmitting board, and be meshed with the front and back central gear respectively, be symmetrical arranged balancing spring on the force transmitting board, both sides before and after scale display panel and digital displaying window lay respectively at, like this, move downward when force transmitting board is stressed, two toothed rack on it drive pinion wheel respectively rotates left and right sides lever and gear wheel, and central gear rotates before and after making, thereby pointer all can be passed through in the two sides, front and back at scale, and index dial and digital displaying window demonstrate the weight number.When double-sided display is inconsistent, can adjust by balancing spring.
The utility model is connected with the band hook below force transmitting board transmission rod constitutes supporting part, like this weight is hung on the hook, by transmission rod force transmitting board is moved downward, and lever and gear wheel and pointer are rotated, and weighs up the weight of object.
The utility model has the bearing frame of band power transmission screw rod above force transmitting board; the scale pan of placing on it matches with index dial; the scale pan is placed on the bearing frame; material is placed in the scale pan, and weight is applied to by the power transmission screw rod it is moved downward, and lever and gear wheel and pointer are rotated; weigh up the weight of object; the utility model not only can be weighed by hook like this, and can claim bulk by the scale pan, and the scale pan can cover on index dial with the protection card at ordinary times.
The utility model has the color display window corresponding with lever and gear wheel, like this, shows by window the most significant digit gravimetric value of weight that except indicating numeral also the circumference at lever and gear wheel is marked with and the corresponding various colors of numeral on the circumference of lever and gear wheel.When pointer turned over 1 circle, numerical aperture showed 1, and the color window then shows the color consistent with digital color.With the clear weight of recognizing.
The Digital-indicating graduated disk scale modern design that the utility model provides, rational in infrastructure, compact, it utilizes lever principle and the regulation and control of multiple spot spring, solved the numerous and diverse problem of sum of errors manufacture craft of amplifying in the range, has the precision height, make characteristics simple, easy to maintenance, especially adopt double-sided display is carried out in index dial, numeral and color combination, word is big simultaneously, and the word degree is wide, clear display, avoid practising fraud, both can hang title simultaneously, can claim by scale pan seat again, have multi-functionally, use easily.
