Description
Technical field
The utility model relates to the good waterproof scale of a kind of vapor-removing performance.
Background technology
Electronic scales belongs to the one of weighing apparatus, utilize recklessly can law or the lever balance theory of power measure the instrument of mass of object.Electronic scales is mainly made up of load bearing system (as the scale pan, scale body), power transmission converting system (as lever transmission system, sensor) and indicating value system (as index dial, electronic display meter) 3 parts.Can be divided into mechanical scale, electronic scales, electro-mechanic scale three major types by structural principle.The workflow of electronic scales is in the time that object is placed on the scale pan, pressure is applied to sensor, this sensor generation deformation, thereby impedance is changed, use driving voltage to change simultaneously, the simulating signal of a variation of output, this signal outputs to Analog to Digital Converter through amplifying circuit, converts the digital signal of being convenient to process to and outputs to CPU s operation control.CPU outputs to display according to keyboard commands and program by this result, until show this result.
Waterproof scale is the one of weight scale/balance, it is many water-proof functions on the basis of common weight scale/balance, the inside of waterproof scale adopts hermetically-sealed construction, the corrosion to sensor elastomer such as liquid, gas prevents from being corrosive, waterproof scale in the market is not still broken away from short destiny of life-span in actual use, the steam of itself enclosing in scale body when this is mainly assembling, the 2nd, the steam infiltrating by sealing strip, sealing film in external environment.Especially after electronic scales shutdown, in scale body, temperature reduces, and while showing as negative pressure with respect to external environment, steam is more easily invaded, and calibration does not simultaneously reach higher precision, and calibration simultaneously improves calibration expense and time greatly, reduces production efficiency, increases cost.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of long service life is provided and calibrates the good waterproof scale of vapor-removing performance easily.
The utility model solves the technical scheme that its technical matters adopts: the good waterproof scale of a kind of vapor-removing performance, there is drain pan and be fixedly connected on the end cap on drain pan, described drain pan and the junction of end cap are provided with waterproof grommet, in drain pan, be provided with dehumidifier and warning horn, on end cap, be provided with dehumidifier button.
Further, described O-ring seal adopts plasticity polyurethane elastomer material to make.
Further, described O-ring seal is hollow structure, is provided with reinforcement in O-ring seal.
Further, the outside surface of the junction of described end cap and drain pan is provided with silica gel tack coat.
The beneficial effects of the utility model are: the utility model is simple in structure, manufacture easy to processly, prevent entering and producing of steam, good sealing effect, and calibration accuracy is high, reduces calibration expense and time, enhances productivity, and reduces costs.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. drain pans in figure, 2. end cap, 3. waterproof grommet, 4. dehumidifier, 5. alarm, 6. dehumidifier button, 7. glue bond layer.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The good waterproof scale of a kind of vapor-removing performance as shown in Figure 1, there is drain pan 1 and be fixedly connected on the end cap 2 on drain pan 1, drain pan 1 is provided with waterproof grommet 3 with the junction of end cap 2, O-ring seal 3 adopts plasticity polyurethane elastomer material to make, can prevent in use entering of moisture, O-ring seal 3 is hollow structure, in O-ring seal 3, be provided with reinforcement, strengthen the sealing effectiveness of O-ring seal 3, reinforcement can ensure the serviceable life of O-ring seal 3, waterproof scale cannot not be used because the damage of O-ring seal 3 causes, increase cost;
The steam of itself enclosing in scale body in the time of assembling, the 2nd, the steam infiltrating by sealing strip, sealing film in external environment.Especially after electronic scales shutdown, in scale body, temperature reduces, while showing as negative pressure with respect to external environment, steam is more easily invaded, so be provided with dehumidifier 4 and warning horn 5 in drain pan 1, on end cap 2, be provided with dehumidifier button 6, exist steam alarm device 5 to give the alarm when drain pan 1 is interior, reminding user, user is dehumidified and is eliminated steam by end cap 2 dehumidifier button 6 above, well extend the serviceable life of waterproof scale, simultaneously making and easy to process;
End cap 2 is provided with silica gel tack coat 7 with the outside surface of the junction of drain pan 1, has further strengthened the waterproof effect of waterproof scale, and enhanced leaktightness performance, reduces production costs.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
