Description
Technical field
The utility model relates to a kind of vernier reading device that can be used for comprising the scale measurer pin-point reading of the transparent material such as graduated cylinder, measuring cup.
Background technology
Existing graduated cylinder, measuring cup etc. with the transparent measurer of Measurement scales, the shortcoming that when ubiquity measures the volume of liquid, reading accuracy is poor, error is large.When chemistry or Bioexperiment, can not the capacity of liquid in precise control amount tool, usually a position integer-bit can only be read according to the scale of measurer itself, particularly when liquid level is between two scales of measurer, the volume of decimal place can only be read in estimation mode, such error is obviously larger, and the consumption of the reagent such as many experiments, medical treatment, solution is that requirement is point-device, by estimating liquid bulk product value significant adverse the drawing in correct conclusion of reading.
Utility model content
The utility model provides a kind of vernier reading device of transparent scale measurer, when reading the liquid quantity value in measurer, can read the volume of liquid accurately, not needing to estimate to read, and high degree improves the accuracy measuring liquid.
The vernier reading device of the utility model transparent scale measurer, the matrix of described device is provided with the visual windows of the master calibration unit on transparent scale measurer described in observable, in described visual windows or its adjacent regions be provided with at least one vernier graduation unit, equidistantly divide in vernier graduation unit and have n vernier graduation, the length of vernier graduation unit is the length of m master calibration in master calibration unit on described transparent scale measurer, n and m is natural number, and n > m, thus make the length of the length < master calibration unit of vernier graduation unit.Wherein, the most frequently used and preferred mode makes n=m+1.
The counting principle of vernier caliper is applied to the reading to liquid volume in the graduated transparent measurer of tool by the utility model cleverly.Such as, 10 master calibrations (as there being 10 evenly divideds in 10mL) are had in a usual master calibration unit, arrange in a vernier graduation unit and have 10 vernier graduations, and make the length of a vernier graduation unit (i.e. 10 vernier graduations) equal with 9 master calibration length in master calibration unit, i.e. n=10, m=9, its numerical relation can be expressed as n=m+1, then the precision of vernier graduation is 1/10 of master calibration precision, as, a master calibration unit is 10mL, a master calibration is 1mL, then the precision of a vernier graduation is 1mL/n=1/10mL, namely vernier scale division value is 0.1mL.The transparent graduated measurer horizontal positioned of liquid will be filled during reading, and 0 scale mark of vernier reading device is alignd with the concave surface of described liquid, along the direction that vernier graduation reading is ascending, the number of this vernier graduation of (or coincidence) and the product of vernier scale division value are the vernier value obtained by aliging with master calibration, and vernier value being added with the master calibration reading value below liquid concave surface and namely obtaining precision is accurately 0.1mL total volume.For the graduated cylinder of 100mL, read measured liquid with the reading device that above-mentioned vernier scale division value is 0.1mL.Suppose that the reading of the graduated cylinder master calibration of liquid concave surface (below) is 58mL, by 0 groove alignment liquid concave surface of vernier reading device, then the 8th bar of vernier graduation line observing reading device aligns with the main scale mark of graduated cylinder, the vernier reading of the liquid volume then in graduated cylinder is " 8 × vernier scale division value=8 × 0.1mL=0.8mL ", namely this measures the cumulative volume of liquid for " 58mL+ vernier reading=58+0.8=58.8mL ", and reading accuracy improves 10 times than directly reading master calibration value.In like manner, if n=20, m=19, that is: the length of 19 master calibrations is divided into 20 vernier graduations, then a vernier calibration of this vernier reading device is 19/20 of a master calibration, have 20 vernier graduations in vernier graduation unit, and total length differs a master calibration with master calibration element length, therefore the precision of vernier scale division value is the 1/20=0.05mL of a master calibration value.Now this vernier reading device can improve 20 times to the reading of liquid volume.Therefore, as long as need according to precision the vernier reading device selecting corresponding calibration, just liquid volume reading in measurer can be accurate to arbitrarily small numerical digit, high degree improves the degree of accuracy of reading.
Be suitable for make vernier reading device together using with transparent scale measurer and depositing, it can be the jacket structure that can match with described transparent scale measurer outer peripheral face by vernier reading device, only need slide along transparent scale measurer length direction when using vernier reading device like this, convenient.
On this basis, vernier reading device can also be provided with the location structure with transparent scale measurer, like this in reading vernier scale division value, and can more accurately and facilitate when observing the vernier graduation number of aliging with master calibration, error in reading can not be there is because of the careless displacement of vernier reading device.
Wherein said location structure is be located at the damping friction part on vernier reading device medial surface.The damping of damping friction part should be not excessive, vernier reading device can be made to be convenient to slide on described measurer, vernier reading device also can not be made after slip completes to move.Except damping friction part, vernier reading device can also be set to internal diameter and be slightly less than measurer external diameter and resilient tube-in-tube structure, or on vernier reading device, be provided with the fixed sturcture of strip, as can the rope fastened of two or flexible rubber ring etc.
When location structure is damping friction part, a kind of alternate configurations of damping friction part is the damping friction bar adapted with transparent scale measurer outer perimeter.
The conveniently loading/unloading of vernier reading device, and location during reading scale, can also have interconnective interface arrangment at the two ends of described damping friction bar, be fixed by vernier reading device.
Concrete a kind of structure is, the visual windows on described vernier reading device is and the stripe-like transparent material structure of the material such as the PVC of the equidirectional extension of master calibration marking mode of transparent scale measurer or engraved structure.Particularly, during transparent material described in employing, visual windows can be merely a transparent window on vernier reading device matrix, also whole vernier reading device matrix all can be set to transparent window.
In order to not affect the reading to master calibration, the visual windows on vernier reading device should be not blocked up, otherwise reading is fuzzy, and easily because of refraction read error, preferred thickness is about 0.3mm.
The vernier reading device of transparent scale measurer of the present utility model, accurately can read the liquid volume of arbitrarily small numerical digit when reading the liquid volume in measurer, high degree improves the accuracy measuring liquid.
Below in conjunction with the embodiment of embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model is only limitted to following example.Do not departing from the above-mentioned technological thought situation of the utility model, the various replacement made according to ordinary skill knowledge and customary means or change, all should be included in scope of the present utility model.
