Abstract
The utility model discloses a portable calculating balance, belonging to the technology of the gravitation metering equipment. In order to improve the measurement precision of the original spring balance and increase the function of calculating the currency amount, a measuring force/error regulating system composed of a spring, a weight hook, a draw rod, a connecting rod and a sector gear is designed to drive a needle pivot, a needle and a fixed panel to comprise a weight display system; according to the principle that the arithmetic product of two digits equals to the summation of each logarithm, a pair of multiplication disk slide rulers composed of a fixed panel and a rotary panel rotating around the fixed panel to realize that the currency amount is reacted by calibrations on the slide ruler when the body weight is correctly weighed. The utility model has the advantages of convenience for carrying, one object with multifunction. The consumer's benefit is maintained.
Description
The utility model relates to a kind of portable spring balance that can calculate the object amount of money, and it belongs to the gravimetric equipment and technology.
Common spring balance only is made up of spring, scale, the hook that hooks weight and tubular shell, elastic deformation X=(F)/(K) when utilizing spring to be subjected to gravity F directly reads weight of heavy on scale, when inconsistent, then will produce certain error with upper spring coefficient of stiffiness K when two.In addition, when needs calculate the amount of money of constant weight, can only do a sum orally or be with computational tool in addition.
The utility model purpose is to propose a kind ofly can improve computational accuracy, and increases and make when scale goes out weight of object by the secondary disc slipstick on the panel, can directly read the portable calculating scale of the new function of the object amount of money.
The utility model is finished by following measure: at first design a sleeve spring dynamometric system, be made up of spring, pull bar and weight hook, hook drives the pull bar compression spring during weighing.Next displacement that makes pull bar connects through connecting rod and sector gear is formed regulating system, through changing connecting rod one end can be at length of spring compressed displacement certain size in the position on the sector gear kidney slot time, the angle of rotation of change sector gear.The 3rd, there is sector gear to drive needle pivot, indicate weight of object.The 4th, read weight weight by a fixed panel, there are fixed panel and a rotary panel to cooperate, calculate the amount of money of various unit price weights.
Fig. 1 is the utility model structural representation; Fig. 2 is the utility model panel scheme synoptic diagram.
To comment embodiment below the utility model, the rotary panel 4 that this device is connected by shell 1, the protecgulum 2 that can rotate, fixed panel 3 and protecgulum, pointer 5, needle pivot 6, sector gear 7, nut 8 and 7 rigidity connection all-in-one-piece gear shaft 9, connecting rod 10, pull bar 11, spring 12, weight hook 13, rivet 14, location-plate 15, holding screw 16, set screw 17, protective shield 18 are formed.Corresponding scale is the disc slipstick that equals the principle design of difference logarithm sum according to the logarithm of two number products on rotary panel 4 and the fixed panel 3, can carry out multiplying, is connected with index line with corresponding weight scale on fixed panel 3.As long as before weighing,, then when indicating weight of object, can on rotary panel 4, directly read the amount of money with equaling normal on the scale secured in alignment panel 3 of object unit price on the rotary panel 4.
The utility model follows these steps to proofread and correct (1) earlier and utilizes standard weights before dispatching from the factory, and changes the position of connecting rod on sector gear 7 kidney slots that set screw 17 connects, and revises the inconsistent and error that causes of spring 12 coefficients of stiffiness.(2) under pull bar 11, the weight hook 13 natural situation vertical, pointer 5 proofreaied and correct pointing to zero kilogram place on the fixed panel 3 with ground level.
When the utility model uses, rotate protecgulum 2 earlier, make normal on the scale secured in alignment panel 3 that equals the object unit price on the rotary panel 4, hook weight with weight hook 13 then, then can read the weight and the amount of money of object simultaneously.
In panel scheme synoptic diagram shown in Figure 2, when 0.5 kilogram of weight less than, then the amount of money can not directly be read.Weight of object can be amplified ten times and locate to read the object amount of money.
After the utility model was implemented, have the following advantages compared with prior art: volume was little, is easy to carry; Measuring accuracy is improved; One-object-many-purposes not only can go out weight of object by scale, and can calculate simultaneously the amount of money of object. Can bring more conveniences to the people in their daily life after adopting this device, safeguard consumer's interests, social effect is good.
