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, and accuracy is high, good stability.When adding on the scale pan that when being claimed thing, the position detector signal of sensor changes, and through 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 through wave filter, A/D converter, carries out data processing, demonstrated automatically by display at last and 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.
The increasing various weighings field that applies to of electronic balance, 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, on balance, cover the installation dust cap, solved the defective of balance absorption dust, but when balance uses, must dust cap have been opened, therefore when balance weighing, dust cap can not play the dustproof effect, thereby influences the degree of accuracy of weighing.
Summary of the invention
To the demand, the invention provides a kind of dustproof balance, through the dust cover design, given balance dustproof effect, improved the accuracy of weighing.
A kind of dustproof balance; 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; It is characterized in that; Described loam cake top is equipped with dust cover, and described dust cover is by support body, and side plate and cover plate are formed.
In the present invention's one preferred embodiment, the support body in the described dust cover is made up of base plate and column, and both can adopt screw to connect.
In the present invention's one preferred embodiment, described bottom edge is provided with capillary groove, and its width is 2-4mm, and the degree of depth is 3-5mm.
In the present invention's one preferred embodiment, adopt hinge to be connected between described column and the side plate, make four side plates all can open and close as required.
In the present invention's one preferred embodiment, adopt the bolt-type hinge to be connected between described column and the side plate, make things convenient for the dismounting and the installation of side plate.
In the present invention's one preferred embodiment, described column top is provided with Magnetic adhesive mat, and the Magnetic adhesive mat polarity that is provided with the cover plate relevant position is opposite, has guaranteed switching performance good between cover plate and the support body.
In the present invention's one preferred embodiment, the magnetic energy radiation areas of Magnetic adhesive mat are less between described cover plate and the support body, can not influence the balance weighing results.
In the present invention's one preferred embodiment, described dust cover adopts the material that quality is light, intensity is high, and this material can be stainless steel, synthetic plastic or polymer composite.
The present invention has disclosed a kind of dustproof balance, and this balance is rational in infrastructure, the weighing process simple and fast; Be characterized in unique dust cover structure design; Can prevent effectively that dust, impurity from getting into the weighing area, reduce the influence of cross-ventilation, improve the accuracy of weighing weighing results; Simultaneously, this dust cover dismounting, easy to assembly can be weighed for the article that exceed its volume equally, and the scope of application is extensive.
