Description
Technical field
The utility model relates to a kind of electronic scales, especially relates to a kind of hermetically sealed waterproof electronic scales.
Background technology
As everyone knows, rainwater, dust, steam and harmful gas etc. all can have influence on the weighing accuracy and the serviceable life of electronic scales.To incorporate electronic scales, LOAD CELLS and printed wiring board all are arranged in the pedestal, in rainwater and dust etc. enters into the scale body, can influence the weighing accuracy of electronic scales, when serious, also can damage electronic scales.And the bracket of its scale pan of traditional electronic scales and LOAD CELLS by screw retention together; again with the scale pan and bracket by covering on the screw retention; therefore between the scale pan and the loam cake not sealing; its aerial solid dust that floats, particulate can enter in the dimple of loam cake from the scale pan and loam cake gap; cause is difficult for cleaning, and breed bacteria.At the problems referred to above, follow-on on the market hermetically sealed waterproof electronic scales, the bottom of scale body seals by being arranged on pedestal and case O-ring seal all around, the elastic seal cartridge of the top of scale body on then on the top by being sleeved on case and the bracket pillar realized sealing, because elastic seal cartridge is to be fixedly connected on to cover, therefore the wall thickness to elastic seal cartridge has strict requirement, otherwise can influence Weighing, so this resilient seal sleeve wall thickness is usually below 0.5mm.Because spring sealed cover is vertical configuration and is installed on bracket pillar and the case, in flushing process to electronic scales, be very easy to cause elastic seal cartridge damaged and lose the sealing function on its scale body top, therefore can not satisfy the not only needs sealing of electronic scales that is used for industries such as food processing, but also the requirement being convenient to clean.On the other hand, when electronic scales was in intact sealing state, because of the variation that the distortion of LOAD CELLS produces scale body internal pressure, the atmospheric pressure outer owing to atmosphere in the scale and scale do not communicate, cause the inside and outside pressure difference of scale, and influence weighing precision and serviceable life.
Summary of the invention
The purpose of this utility model is to overcome weak point in the prior art, provides a kind of simple in structure, can the parts in the scale body all be sealed, and can keep the scale internal and external pressure balance again, can keep the hermetically sealed waterproof electronic scales of weighing precision.
The utility model is that the technical scheme that achieves the above object is: a kind of hermetically sealed waterproof electronic scales, comprise pedestal, case, LOAD CELLS, the scale pan and printed wiring board, it is characterized in that: described pedestal periphery is provided with " " shape seam, base bottom surface is connected with base plate, case is connected on the pedestal and the periphery of its bottom surface is arranged on the base plate, the O-ring seal that is installed in pedestal " " the shape seam is against respectively on base plate and the case, LOAD CELLS is fixed on the pedestal by bottom bracket, the scale pan is connected with LOAD CELLS by bracket, and printed wiring board is fixed on the pedestal; Described case top is equipped with support, and an elastic seal cartridge is connected on bracket and the support; Described pedestal also has the air hole that communicates with the bottom, and the diaphragm of energy waterproof and breathable is installed on the air hole.
The utility model has the following advantages after adopting technique scheme: 1, simple and practical.The utility model adopts O-ring seal to seal between case and pedestal and base plate, support has been set up at the top of case, support and bracket are remained basically stable, elastic seal cartridge is installed between support and the bracket, make the elastic seal cartridge installation that is the level of state substantially, especially to the dashing in Xian's process of electronic scales, elastic seal cartridge can directly not impacted, and improves its serviceable life.2, good seal performance.Seal by an O-ring seal between case, base plate and the pedestal of the utility model scale body, and the top of scale body makes by elastic seal cartridge and seals between the scale pan and the case, can realize the thorough seal between the scale pan, pedestal and the case, because spring sealed cover can not influence weighing precision, therefore can guarantee weighing precision.3, under the electronic scales sealing state, can keep the inside and outside pressure equilibrium of scale body.The utility model is provided with the air hole that communicates with the bottom on pedestal, sealing one deck is used for the diaphragm of waterproof and breathable on the air hole, under the prerequisite of waterproof, damp-heat air in the scale body can be discharged, and institute's pressure that produces changes when LOAD CELLS is out of shape, also can make the inside and outside pressure communication of scale body, keep the balance of the inside and outside pressure of scale body, thereby guarantee the weighing precision of electronic scales by this diaphragm.
