Abstract
The invention provides a novel dustproof balance. The balance comprises a bottom shell, a mother board, a sensor, a weighing plate bracket, a leveling bolt, a power supply, a weighing plate, an upper cover and a display screen connected with the mother board, wherein the upper cover is provided with with a transparent dustproof cover. The invention discloses a novel dustproof balance. The balance has the advantages of reasonable structure, simple and fast weighing process and high accuracy, has the characteristics that a special structural design of the dustproof cover can prevent dust adsorption and increase the weighing accuracy, and also has a safety protecting effect on both a weighed article and a human body.
Description
Technical field
The present invention relates to a kind of balance, be specifically related to a kind of electronic balance, belong to the electronic balance technical field with dust reduction capability.
Background technology
Electronic balance is the condensation products of sensing technology, Analog Electronics Technique, Digital Electronic Technique and microprocessor technology development, has automatic calibration, shows automatically, multiple functions such as peeling is heavy, automaticdata output, automatic fault track, overload protection.Electronic balance uses electro magnetic force sensor usually, forms a close-loop automatic adjustment system, accuracy height, good stability.When adding on the scale pan that when being claimed thing, the position detector signal of sensor changes, and by the amplifier feedback electric current in the cell winding is increased, this electric current produces a feedback force and adds load and balance each other in the stationary magnetic field; Simultaneously, the magnitude of voltage of this electric current on measuring resistance Rm sent into microprocessor by wave filter, A/D converter, carries out data processing, demonstrated automatically by display at last to be claimed amount numerical value.Simple in structure based on it, cost is low, advantage such as convenient to use, the novel electron balance is widely used.
Electronic balance more and more applies to various weighings field, and it has weighing advantage easily and fast.Because balance belongs to exact instrument, its degree of accuracy of common electronic balance can reach per mille, or even ten thousand/, the dust that therefore is adsorbed on balance weighing pan surface might directly influence its weighing accuracy.In the prior art, cover the installation dust cap on balance, solved the defective of balance absorption dust, but when balance uses, dust cap must have been opened, therefore when the balance weighing, dust cap can not play the dustproof effect, thereby influences the degree of accuracy of weighing.
Summary of the invention
At the demand, the invention provides a kind of novel dustproof balance, by the dust cover design, given balance dustproof effect, improved the accuracy of weighing.
A kind of novel dustproof balance, this balance comprise drain pan, motherboard, sensor, weighing pan support, levelling bolt, power supply, weighing pan, loam cake and the display screen that links to each other with motherboard, and described loam cake is equipped with transparent dust cover.
In a preferred embodiment of the present invention, described transparent dust cover is transparent plastic material or organic glass material.
In a preferred embodiment of the present invention, described dust cover is hollow rectangular structure, and the bottom hollow out places on the balance to cover.
In a preferred embodiment of the present invention, but described dust cover both direction open simultaneously, conveniently to take article.
In a preferred embodiment of the present invention, described dust cover and balance loam cake contact position are provided with groove, can improve the stability of dust cap.
In a preferred embodiment of the present invention, described dust cover integral body can be dismantled, the convenient cleaning.
The present invention has disclosed a kind of novel dustproof balance, and this balance is rational in infrastructure, the weighing process simple and fast, and the degree of accuracy height is characterized in unique dust cover structure design, can prevent dust absorption, improves the accuracy of weighing; Simultaneously, symmetrical heavy articles and human body self have all played the effect of a safeguard protection.
Description of drawings
Fig. 1 is the synoptic diagram of dustproof balance of the present invention.
Annex mark is as follows in the accompanying drawing: 1, dust cover, 2, loam cake.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
See also Fig. 1, Fig. 1 is the synoptic diagram of dustproof balance of the present invention, this balance comprises drain pan, motherboard, sensor, weighing pan support, levelling bolt, power supply, weighing pan, loam cake and the display screen that links to each other with motherboard, and described loam cake 2 is equipped with transparent dust cover 1.
Innovative point of the present invention is the design of dust cover 1, and dust cover 1 is transparent plastic material or organic glass material, can also be other material; Dust cover 1 is hollow rectangular structure, and the bottom hollow out places on the balance to cover, but both direction open simultaneously, conveniently to take article; Dust cover 1 is provided with groove with balance loam cake 2 contact positions, can improve the stability of dust cap, and simultaneously, dust cover 1 can carry out integral demounting, the convenient cleaning.
The present invention has disclosed a kind of novel dustproof balance, and its characteristics are: this balance is rational in infrastructure, the weighing process simple and fast, and the degree of accuracy height is characterized in unique dust cover structure design, can prevent dust absorption, improves the accuracy of weighing; Simultaneously, symmetrical heavy articles and human body self have all played the effect of a safeguard protection.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
