Abstract
The utility model relates to the technical field of a measuring instrument, which is suitable for the technical field of laboratory. The utility model comprises a metering tube casing, a metering tube plug, a middle sleeve tube, a screw rod and a lifting guide rod, wherein a spring is arranged on the metering tube plug, the lower end of the screw rod is provided with opening and closing screw threads 7, 8 and a dial capable of rotating is arranged on the plane of the sleeve tube. The utility model has the advantages of accurate liquid drip and discharge, minute dripping, convenient, quick and safe operation and little abrasion and an indexing disc of 1 ml is 0.001 ml on visualness.
Description
The utility model relates to the measurement instrument technical field, is suitable for examination, laboratory with moving liquid, tubular type liquid feeding and titration technique field in the liquid meter.
Existing conventional suction pipe, transfer pipet, buret are that the ear washing bulb imbitition is set on the glass tube, drip naturally after the imbibition, during use, determine the time of following of nature regulation with water gaging method, pore size constant volume, speed.Operating personnel in use very easily produce artificially out of control, residual, wall built-up, and sight line is poor, causes systematic error, are generally called half poor, and small value can't be discerned on end face.
The purpose of this utility model is, a kind of above-mentioned defective that overcomes is provided, accurately and fast, conveniently, safety multi-functional meter.
The technical solution of the utility model is achieved in that
The utility model comprises the gauge line overcoat, the metering pipe close, middle sleeve, screw rod, lifting guide pillar, be with back-moving spring 5 on the metering pipe close 4, and by pad 3 location, the lower end of screw rod 13 is provided with the clutch thread 7 and 8 of scalable location, on the screw rod 13 on the middle sleeve 6 plane be provided with rotating index dial.
The technical scheme that the utility model also can be taked is said rotating index dial, comprises bearing cap 11 and graduated scale 10, is provided with bearing 9 or at least 3 balls between the surface of contact of bearing cap 11 and graduated scale 10.
The better technical scheme of the utility model is vertically to be provided with elongated slot on the screw rod 13, and bearing cap 11 is fixed on by fastening nail 12 in the elongated slot of screw rod 13, and lifting guide pillar 14 is located in screw rod 13 cavitys.
The technical scheme of the utility model the best is that middle sleeve 6 adopts screw thread 2 to be connected with gauge line overcoat 1, and gauge line overcoat 1 is provided with scale.
The utility model has the advantages that:
1, because employing by the pitch control scale of screw rod, so row's dropping liquid is accurate, can be dripped the small 1ml of value, index plate 0.001ml directly perceived.
2, owing to be provided with back-moving spring beyond the Great Wall at gauge line, be provided with the clutch thread of scalable, location in the screw rod lower end, screw rod can rotate the adjusting index dial according to the needs of operation, again can upper and lower motion in elongated slot, so easy to operate, quick, safety.
3, the metering pipe close sucks liquid by finish grinding close joining, and extruding row drip, and it is little to wear and tear.
Accompanying drawing is a structural representation of the present utility model:
1 is gauge line overcoat, the 2nd among the figure, connecting thread, the 3rd, pad, the 4th, metering pipe close, the 5th, spring, the 6th, middle sleeve, 7, the 8th, clutch thread, the 9th, bearing, the 10th, graduated scale, the 11st, bearing cap, the 12nd, fastening nail, the 13rd, screw rod, the 14th, lifting guide pillar.
Introduce embodiment in conjunction with the accompanying drawings:
As shown in the figure, the utility model comprises the meter of the similar needle cylinder injection device shape of being made up of gauge line overcoat, metering pipe close, middle sleeve, screw rod, lifting guide pillar, on metering pipe close 4, be with back-moving spring 5, and by 3 grades of location of pad, in the lower end of screw rod 13 7 and 8 two clutch threads are set, when not needing to move up and down, but still rotatable, when unclamping the clutch thread, this moment is because the effect of back-moving spring 5 can drive lifting guide pillar 14 and screw rod 13 moves upward.Rotating index dial is located on the last plane of middle sleeve 6 on the screw rod 13, and the screw rod rotation presses down the usefulness for titration.Screw rod is regulated quantitative imbitition arbitrarily, and the pressing guide rod rises and moves liquid, liquid feeding function, and the middle sleeve upper end is provided with the zero line pointer, points to index dial, end of operation value directly perceived.
Rotating index dial comprises bearing cap 11 and graduated scale 10, and graduated scale is enclosed within on the bearing ectosome, and bearing cap 11 is provided with bearing 9 or at least 3 balls with the surface of contact of graduated scale 10, the convenient rotation.
Screw rod 13 is provided with elongated slot, and bearing cap 11 is fixed on by fastening nail 12 in the elongated slot of screw rod 13, and lifting guide pillar 14 kinks are in screw rod 13 center cavities.Middle sleeve 6 adopts with gauge line overcoat 1 and is threaded, and gauge line overcoat 1 is provided with scale, and the scale amount is revolved 1/10th or 1/20th big lattice that equals serial calibration gauge buret a week.
Claims (5)
1, a kind of multi-functional meter, it comprises the gauge line overcoat, the metering pipe close, middle sleeve, screw rod, lifting guide pillar, it is characterized in that, be with back-moving spring 5 on the metering pipe close 4, and by pad 3 location, the lower end of screw rod 13 is provided with the clutch thread 7 and 8 of scalable location, on the screw rod 13 on the middle sleeve 6 plane be provided with rotating index dial.
2, multi-functional meter according to claim 1 is characterized in that, said rotating index dial comprises bearing cap 11 and graduated scale 10, is provided with bearing 9 or at least 3 balls between the surface of contact of bearing cap 11 and graduated scale 10.
