Abstract
The invention provides a dustproof balance. The dustproof balance comprises a bottom shell, a main board, a sensor, a weighing plate support, a leveling bolt, a power supply, a weighing plate, an upper cover and a display screen which is connected with the main board. The dustproof balance disclosed by the invention is reasonable in structure, simple and rapid in weighing process and high in accuracy and has the characteristic that: a dustproof cover is arranged on the upper cover, so dust can be effectively prevented from contacting the upper cover and weighing accuracy is enhanced.
Description
Technical field
The present invention relates to a kind of balance, be specifically related to a kind of electronic balance with dust reduction capability.
Background technology
Balance is the weighing apparatus in a kind of ancient times, produces early, and to Late Spring and Autumn Period, the manufacturing technology of day gentle counterweight is quite accurate.Do crossbeam with bamboo chip, silk thread is for carrying knob, and the two ends Pueraria lobota is hanged a bronze medal dish.The back is cumbersome because of the balance weighing apparatus weight, changes " select " into, just uses balance during the little thing of weighing.Along with progress of science and technology, this ancient instrument of balance has also obtained very big development, differential label balance, Roberval's balance, resistance balance, single-deck unequal arm mechanical balance, electric light resistance balance, electronic balance etc. have appearred, the material category of weighing is more and more abundanter, the precision of weighing is also more and more higher, and the scope of application is more and more wide.
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.
Summary of the invention
At the demand, the invention provides a kind of dustproof balance, by reasonable structural design, improved the accuracy that balance is weighed.
The present invention is a kind of dustproof balance, and this dustproof 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.
In a preferred embodiment of the present invention, described loam cake place is provided with dust cap, can effectively intercept dust contact loam cake, improves the degree of accuracy of weighing.
In a preferred embodiment of the present invention, described dust cap adopts bolt to be connected with loam cake, and dust cap detachably cleans.
In a preferred embodiment of the present invention, described dust cap can adopt phenolic resin material to be prepared, and has higher intensity, impact resistance, thermotolerance and corrosion stability.
In a preferred embodiment of the present invention, described dust cap and loam cake are transition fit, have certain water-proof function, and electronic balance is shielded.
The present invention has disclosed a kind of dustproof balance, and this balance is rational in infrastructure, the weighing process simple and fast, and the degree of accuracy height is characterized in being provided with dust cap at the loam cake place, can effectively intercept dust contact loam cake, has improved the degree of accuracy of weighing.
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 cap, 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, because these all are the known technology of this area for drain pan, motherboard, sensor, weighing pan support, levelling bolt, power supply, weighing pan, loam cake, so do not do detailed explanation, innovation part of the present invention is that the loam cake place is provided with dust cap, when balance is on the shelf, dust cap can be closed, thus the cleaning that keeps weighing pan as far as possible, and then effectively improve the accuracy of balance weighing; Wherein said dust cap adopts bolt to be connected with loam cake; dust cap detachably cleans; dust cap can adopt phenolic resin material to be prepared; have higher intensity, impact resistance, thermotolerance and corrosion stability; and dust cap and loam cake are transition fit; have certain water-proof function, electronic balance is shielded.
The present invention has disclosed a kind of 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 being provided with dust cap at the loam cake place, can effectively intercept dust contact loam cake, has improved the degree of accuracy of weighing.
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.
