Abstract

A balance with dial and bearing hook for calculating account is composed of circular weight indicating disk and annular logarithm slide rule, which is composed of bearing hook, rack engaged with gear fixed with pointer, fixed scale of annular logarithm rule fixed to the scale of circular weight indicating disk, vernier with starting line and movable scale. The utility model discloses not only convenient to carry, easy to operate, the reading is directly perceived moreover, calculates the accuracy, can avoid misoperation effectively.

Description

Balance with graded disk capable of doing accounts

The utility model relates to a kind of daily living article, and particularly a kind of is weighing and calculations incorporated the scale dial that can do accounts of one.

People often run in daily life and buy the weighing article, worry to give short weight and the phenomenon of blunder the account.Spring balance that thereupon arises at the historic moment and home-use counter though can solve some problems, because of existing spring balance index dial is the linear reading dial, are difficult for reading, and resolution is low, influences its use.Family's counter also occurs misoperation easily and causes calculating inaccurate, is difficult to find that accuracy is calculated in influence.The two uses respectively in addition, carries and operate equal inconvenience.

The purpose of this utility model provides a kind of scale dial that can do accounts, and it is not only easy to carry, operation easily, and also reading is directly perceived, calculates accurately, can avoid misoperation effectively.

The purpose of this utility model is achieved in that this device is one to have the spring balance of pointer, index dial and load-bearing hook, wherein index dial is a disc, it is made up of circular weight display disc and annular logometer, the tooth bar that links together with the load-bearing hook is meshed with the gear that is fixed with pointer, the scale and the circular weight display disc scale respective fixation of annular logarithm chi, the vernier that annular logarithm chi has hair line rotates relative to scale with moving chi.

Because the utility model adopts the version of rack and pinion engagement, pointer is rotated along the disc index dial, fundamentally changed traditional spring balance linear reading dial structure, and with the combination with it of annular logarithm chi, so spring balance and logometer organically are combined into one, not only easy to carry, operation easily, and reading is directly perceived, calculates accurately, avoid conventional springs scale reading disadvantage inaccurate and home-use counter counting loss to take place, this device is easy to apply.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure synoptic diagram of the utility model.

Fig. 2 is the cut-open view of Fig. 1 along the A-A line.

Fig. 3 is tooth bar, gear transmission structure synoptic diagram.

Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device is improved to form on the structure of existing spring balance.It comprises housing, is assembled in spring 1, the tooth bar 3 that is meshed and parts such as gear 2, annular logometer and circular weight display disc 4 in the housing.Wherein be fixed on the circular weight display disc 4 on the housing and be carved with the weight indicated value, and corresponding with indicated value on the scale 6 of annular logarithm chi, and display disc 4 all maintains static with scale 6.Pointer 5 is fixed on the gear 2, and rotates along display disc 4 with the rotation of gear 2.The tooth bar 3 that is meshed with gear 2 is hinged on respectively on spring 1 and the load-bearing hook.Weight on the load-bearing hook deforms spring 1, and tooth bar 3 moves down thereupon, and tooth bar 3 drives the gear 2 that is engaged with and rotates, and pointer 5 just indicates the weight of heavy value on display disc 4.The removal weight, spring 1 restores, and tooth bar 3 driven gears 2 make pointer 5 get back to original position.Indicated value on the annular logarithm chi and the indicated value on the display disc 4 can be determined according to actual needs.The moving chi 7 of annular logarithm chi all can rotate relative to scale 6 with the transparent vernier 8 that has hair line, so that calculate corresponding numerical value.Annular logarithm chi is identical with the principle of work of general slipstick.The using method of indicating section of weighing is identical with the pronunciation of tolerance scale commonly used.

Adjust weight after utilizing the utility model or learning article unit price, total price in the price that calculates article behind the reading of weighing.1.25 yuan of example known contents unit prices, calculate total price after weighing, can earlier the hair line of vernier 8 be aimed at the indicated value " 1.25 " on the moving chi 7, weighed amount, pointer 5 points to " 3 " on the display disc 4, and then article weigh 3 kilograms, rotates the moving chi 7 on the logarithm chi then, rotate simultaneously together with vernier 8, the vernier hair line is overlapped with scale value " 3 " on the scale 6.At this moment, scale value on the scale 6 " 1 " and moving chi 7 pairing scale values are the article total price 3.75(unit that asks).

As 12 yuan of 2.5 yuan of known purchase unit prices and total prices, need check Item Weight.Can be earlier the scale value of moving on the chi 7 " 12 " be overlapped with scale value " 2.5 " on the scale 6, at this moment, the scale value " 4.8 " of vernier hair line indication on scale 6 is 4.8 kilograms of Item Weights, at last article are placed on weighing on the load-bearing hook, as the scale value of pointer 5 on display disc 4 is " 4.8 ", proves that then Item Weight is accurate.

The utility model method of operating is easy, is very easy to grasp.Therefore, it also can be used as a kind of intellectual service toy or dynamometer, also can help the student to carry out the practice tools of multiplication and division.

Claims (1)

1, a kind of scale dial that can do accounts that has pointer, index dial and load-bearing hook, it is characterized in that index dial is a disc, it is made up of circular weight display disc and annular logometer, the tooth bar that links together with the load-bearing hook is meshed with the gear that is fixed with pointer, the scale and the circular weight display disc scale respective fixation of annular logarithm chi, the vernier that annular logarithm chi has hair line rotates relative to scale with moving chi.
