The utility model relates to a waterproof electronic scale.

[ background of the invention ]

An electronic scale is a kind of weighing apparatus, and is a tool for measuring the mass of an object by using hooke's law or the principle of lever balance of force. According to the structural principle, the mechanical scale can be divided into three categories, namely a mechanical scale, an electronic scale and an electromechanical combination scale.

The electronic balance is mainly composed of a bearing system such as a scale pan, a scale body, a force transmission conversion system such as a lever force transmission system, a sensor, a value indicating system such as a dial and an electronic display instrument 3.

When an object is placed on the scale, pressure is applied to the sensor, which deforms elastically, causing a change in impedance and, at the same time, a change in the applied excitation voltage, outputting a changing analog signal. The signal is amplified by the amplifying circuit and output to the analog-to-digital converter. The digital signals converted into the signals convenient for processing are output to the CPU for operation control. The CPU outputs such results to the display according to the keyboard commands and the program. Until such a result is displayed. The electronic scale adopts an electronic weighing device integrating modern sensor technology, electronic technology and computer technology, can meet and solve the 'quick, accurate, continuous and automatic' weighing requirement in real life, and effectively eliminates human errors, so that the electronic scale is more in line with the application requirements of legal metering management and industrial production process control.

The waterproof electronic scale is characterized in that the scale pan is a square plate, and the height of the clamping groove is equal to the thickness of the scale pan.

The utility model has the advantages that:

the utility model discloses a be equipped with the flexible seal ring that can seal the upper wall hole between sensing support and the pan of steelyard, seal ring still is equipped with the raised grain, and when seal ring was strikeed to the internal atmospheric pressure of balance, the impact can effectively be alleviated to the raised grain, and seal ring's sealed effect can not receive the influence, and water-proof effects is good, long service life.

The utility model discloses a both sides edge of panel lower wall symmetry is equipped with and supplies the rectangular draw-in groove of scale male, and a side of draw-in groove is equipped with the limiting plate. The panel is connected with the scale pan in a horizontal and transverse inserting and fixing mode, the connection is tight, the panel is not easy to fall off, and the scale pan is simple in structure, firm in fixing and low in cost.
