Abstract
A connecting and guiding tube for chemical inspection consists of a guiding tube body, a guiding tongue, a connecting and guiding tube tongue and a connecting and guiding tube. The guiding tongue adopts an inner concave surface-shaped structure and is arranged inside the guiding tube body; a through hole is formed in a position which is slightly lower than the wall of the guiding tube body and is corresponding to the guiding tongue; the connecting and guiding tube is arranged in the through hole; the connecting and guiding tube tongue is arranged on a port inside the guiding tube body to be convenient for connecting and guiding fractions flowing down from the guiding tongue; and a handle is arranged at one end of the outer part of the guiding tube body. The connecting and guiding tube has the advantages of simple structure, convenient use, low manufacturing cost and convenient popularization. When the connecting and guiding tube is used for collecting the fractions, the fractions flow to the connecting and guiding tube tongue along the guiding tongue, then flow into the connecting and guiding tube from the connecting and guiding tube tongue and are finally guided out by the connecting and guiding tube; and after the fractions at a certain temperature are collected, fractions at other temperatures can flow into a receiver through rotating the handle on the connecting and guiding tube when being required to be collected. Therefore, the utility model avoids the replacement of the connecting and guiding tube or the receiver and also reduces the risk caused by inflammable or poisonous fractions during the operation.
Description
Technical field:
The utility model relates to the chemical test instrument, relates in particular to chemical analysis with connecing skirt.
Background technology:
Connecing skirt in chemical experiment or check is the laboratory apparatus of using always, the present skirt that connects mostly is that single head connects skirt, this connects the distillations of skirt when collecting different temperatures must and connect skirt separately with receiver, change receiver, if when in this type of experimental implementation, running into inflammable or poisonous fraction, danger is bigger, and the error of experiment is also bigger.Existing vacuum connects skirt and costs an arm and a leg, and operation is also inconvenient.
The utility model content:
The utility model overcomes the part of the deficiencies in the prior art, provides chemical analysis a kind of simple in structure, easy to use with connecing skirt.
Chemical analysis described in the utility model is with connecing skirt, include skirt main body, guide tongue and connect skirt and form, inside in said skirt main body is provided with guide tongue, said guide tongue is the planar structure of indent, the skirt main wall of guide tongue correspondence slightly by under the position be provided with through hole, be provided with in the through hole and connect skirt, the said port that connects skirt skirt body interior is provided with and connects the skirt tongue, draws the distillations that flows down on the guide tongue so that connect; On an end of skirt main body outside, be provided with handle at the said skirt that connects.
Chemical analysis described in the utility model is with connecing skirt, and is simple in structure, easy to use, and cost of manufacture is low, is convenient to promote.Use the utility model when collecting distillations, distillations flows to along guide tongue and connects the skirt tongue, flow into again and connect skirt from connecing the skirt tongue, derive by connecing skirt, when having collected the distillations of uniform temperature, in the time of need regathering the distillations of other temperature, can rotate the handle that connects on the skirt this moment, makes distillations flow into receiver.Avoided more changing-over skirt or receiver, also reduced inflammable or poisonous distillations and when operation, brought danger.
Description of drawings:
Accompanying drawing 1 is the chemical analysis described in the utility model structural representation that connects skirt.1-skirt main body 2-guide tongue 3-meets skirt tongue 4-and connects skirt
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: chemical analysis described in the utility model is with connecing skirt, include skirt main body 1, guide tongue 2, connect skirt tongue 3 and connect skirt 4 and form, be provided with guide tongue 2 in the inside of said skirt main body 1, said guide tongue 2 is the planar structure of indent, the skirt main wall of guide tongue 2 correspondences slightly by under the position be provided with through hole, be provided with in the through hole and connect skirt 4, the said port that connects skirt 4 skirt main bodys 1 inside is provided with and connects skirt tongue 3, draws the distillations that flows down on the guide tongue 2 so that connect; On an end of skirt main body 1 outside, be provided with handle at the said skirt 4 that connects.Chemical analysis described in the utility model is with connecing skirt, and is simple in structure, easy to use, and cost of manufacture is low, is convenient to promote.Use the utility model when collecting distillations, distillations flows to along guide tongue 2 and connects skirt tongue 3, flow into again and connect skirt 4 from connecing skirt tongue 3, derive by connecing skirt 4, when having collected the distillations of uniform temperature, in the time of need regathering the distillations of other temperature, can rotate the handle that connects on the skirt 4 this moment, makes distillations flow into receiver.Avoided more changing-over skirt 4 or receiver, also reduced inflammable or poisonous distillations and when operation, brought danger.
