Above-mentioned purpose of the present utility model realizes by following technical proposal: one can increase dropper, it comprises bladder, push pipe, growth portion and straight tube four part, bladder is arranged on push pipe upper end, growth portion connects and is arranged between push pipe and straight tube that (namely top, growth portion is connected to push pipe lower end, increase subordinate portion and be connected to straight tube upper end), growth portion comprises leather sheath and tube connector, is connected between push pipe with tube connector and between tube connector with straight tube by leather sheath.
Increase in dropper above-mentioned, as preferably, described bladder is calabash shaped structure.
Increase in dropper above-mentioned, as preferably, described push pipe, tube connector and straight tube are the pipe be made of plastics.
Increase in dropper above-mentioned, as preferably, described straight tube forms graduation mark in forming process.
Increase in dropper above-mentioned, as preferably, described straight tube lower semisection is tapered, reduces gradually from the upper end of taper to bottom diameter.
Increase in dropper above-mentioned, as preferably, be provided with mouth of pipe plug in described straight tube top ports, mouth of pipe plug has the through hole be communicated with straight tube by growth portion leather sheath.(when not using, remove mouth of pipe plug, be convenient to the volatilization of reagent)
Compared with prior art, the utility model has following beneficial effect:
1, dropper of the present utility model is provided with growth portion, and growth portion can connect the tube connector of different length by leather sheath according to the environment of titration, and adjustment dropper length, facilitate liquor to draw, it is more convenient to operate.
2, in prior art, the pipe of dropper is nearly all made with glass, cost is high on the one hand, inconvenience transport on the one hand, transport is deposited in process and very easily breakage is occurred, increase storage and cost of transportation, and (scale is fixed in advance when producing to be not easy to mark scale on dropper, cannot adjust as required), pipe in the utility model dropper, the tube connector as push pipe, straight tube and growth portion is all made of plastics, and quality is light, scale cost of manufacture is low, can portray at any time and adjust, not only cost be low, and convenience stores, transport.
3, the straight tube in the utility model dropper just can form graduation mark in forming process, can accurately carry out getting liquid, transfer, convenient and practical.
4, be provided with mouth of pipe plug in the straight tube top ports in the utility model dropper, be convenient in use deposit the short-term of liquor, clog rear liquor and be not vulnerable to environmental pollution or reaction, when not using, remove critical point plug, ensure that dropper is inner dry.
5, other can also fractionation after cleaning carries out rapid draing, and the dry efficiency with using of raising, reduces residual night and retain, and is convenient to clean totally.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can increase dropper.
In figure, 1, bladder; 2, push pipe; 3, growth portion; 4, straight tube; 5, leather sheath; 6, tube connector; 7, graduation mark; 8, taper; 9, mouth of pipe plug.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, one can increase dropper, described dropper comprises bladder 1, push pipe 2, growth portion 3 and straight tube 4 four part, bladder 1 is arranged on push pipe 2 upper end, growth portion 3 connection is arranged between push pipe 2 and straight tube 4, growth portion 3 comprises leather sheath 5 and tube connector 6, is connected between push pipe 2 with tube connector 6 and between tube connector 6 with straight tube 4 by leather sheath 5.Growth portion can according to the environment of titration by leather sheath connect different length, different number tube connector flexible modulation dropper titration height, make transfer liquid can not cause waste not because of length in titration process, also can not pollute because length exposes the long time not in atmosphere in titration process.
Further preferably, bladder 1 is in calabash shaped structure.
Further preferably, push pipe 2, tube connector 6 and straight tube 4 are the pipe be made of plastics, and not only cost is low, and conveniently to store, transport.Again further preferably, straight tube 4 forms graduation mark 7 in forming process, quantitatively accurately, can accurately carry out getting liquid, transfer, convenient and practical.
Further preferably, straight tube 4 lower semisection tapered 8, reduces from the upper end of taper 8 gradually to bottom diameter.
Further preferably, be provided with mouth of pipe plug 9 in straight tube 4 top ports, mouth of pipe plug has the through hole be communicated with straight tube 4 by growth portion leather sheath 5, when not using, removes mouth of pipe plug, is convenient to the volatilization of reagent, ensures that dropper is inner dry.
