Description
Technical field
The utility model relates to the example platform elevating mechanism of liquid table/interfacial tension tester, especially manual sample platform lifting mechanism.
Background technology
Liquid table/interfacial tension the tester of existing employing hand-operated lifting example platform, lifting structure mainly contains two kinds: as shown in Figure 1 a kind of, be the lifting structure that adopts gear, tooth bar; Another kind is the lifting structure that adopts screw rod, nut as shown in Figure 2.They respectively have relative merits, and the former advantage is simple to operate, and rising or falling speed is fast, and Measuring Time is shorter.Shortcoming is that the location is inaccurate, does not have auto-lock function, and wayward platinum plate inserts the position of liquid, and measuring error is big.Especially when measuring repeatability, each example platform lifting position is inconsistent, and the measuring repeatability error of generation is bigger; Latter's advantage is that hoistable platform is slow, and auto-lock function is arranged because of lifting is a rotating screw bolt, the location calibration, measure more correct, so each measuring repeatability is better.Shortcoming is that measuring process is consuming time many, so work efficiency is lower because the empty distance of running of example platform lifting is big;
The utility model content
The purpose of this utility model is to keep the advantage of prior art, improve its deficiency, desire is by better simply architecture advances, provide a kind of fine setting screw rod, nut of can utilizing correctly to locate, again can be in non-measurement stroke, allow the example platform fast lifting, shorten Measuring Time and be convenient to the manual sample platform lifting mechanism that operating personnel control the liquid table/interfacial tension tester of location.
The utility model is achieved in that same example platform elevating mechanism is divided into finely tunes at a slow speed lifting example platform part and fast lifting example platform part, make this two parts is ingenious and combine, both reached and can finely tune example platform at a slow speed, but fast lifting example platform again.The utility model adopts the eccentric fast lifting example platform of being with of hand mechanism.This mechanism can select for use by following and 1. form to 5. member, the i.e. mechanism of this fast lifting example platform, comprise on the axis hole that 1. is contained in support with this axis hole and being slidingly matched, and one end be equipped with (can be the fixed installation, also can be chimeric installation) axle of manual handle, 2. be packed in the eccentric wheel on the axle, 3. be packed in the location axle bed on support top with running through a top of the trellis, 4. be contained in the axle bed of location, below the nut and with the location axle sleeve of lifting screw concentric, 5. an end is fixed in that the liquid table/(this fixes interfacial tension tester base plate upside, both can directly be contained in above the base plate, also can be fixed in the base plate upside) by support or other members, the other end is fixed in the extension spring on the tension spring hook of locating the axle sleeve lower end, and the location axle sleeve closely contacts with eccentric outer rim under the effect of this extension spring.
To locate axle sleeve for ease of the simple and easy perception fast lifting mechanism of operator and send to most significant digit, lowest order, the utility model is also special to be fixed with two respectively to the position circle on the axle of support side, their periphery upper process support the position bar respectively can with the low level rod that is packed in the support both sides, high-order rod against, when one support position circle and low level rod against the time, the eccentric wheel axle center is nearest from the location axle sleeve, be that fast lifting mechanism will be located axle sleeve and be delivered to lowest order, when another support position circle and high-order rod against the time, the eccentric wheel axle center is from locating axle sleeve (4) farthest, and promptly fast lifting mechanism will be located axle sleeve and be delivered to most significant digit.
In addition, for ease of the simple and easy control of operator at a slow speed elevating mechanism will finely tune lifting screw and send to what kind of trim locations, the utility model spy allows described nut upper periphery that anti-skidding line is arranged, lower, outer perimeter has the scale corresponding circle arc angle, that be used to indicate lifting position for indicating, the locating shaft set upper side is shown with the datum line parallel with axle, on this datum line and the described scale 0 degree line is on time, and the relative nut in upper surface of fine setting screw rod is nearest, promptly finely tunes screw rod and is in lowest order.By the scale indication of alignment fiducials line, be convenient to operator's repeated test, accurately locate.
Thereby the utility model both reached and can accurately finely tune example platform at a slow speed finely tuning at a slow speed lifting example platform part and ingenious the combining of fast lifting example platform part, but fast lifting example platform again.Utilize the utility model, can save Measuring Time, increase work efficiency and improved stability and repeated, operation is also convenient, utilizes the measurement reliability of its liquid table/interfacial tension tester to be much improved.
Further introduce the utility model below in conjunction with accompanying drawing for embodiment.
