Description

Magnetic susceptibility is measured pipe

Technical field

The utility model relates to the glass container that is used to hold sample in the chemical experiment.

Background technology

In the magnetic susceptibility determination test of material, as shown in Figure 1, sample is contained in magnetic susceptibility and measures in the pipe 10, the gravity that magnetic susceptibility is measured pipe 10 is supported by balance fully, the sample that magnetic susceptibility is measured in the pipe 10 is arranged in magnetic field, along with sample is magnetized, magnetic susceptibility is measured pipe 10 suffered gravity and must be changed, and the variation of this gravity can show by the reading of balance.Testing crew changes the related parameter that has that just can grasp the test of sample magnetic susceptibility by the reading of balance, and then calculates the magnetic susceptibility of sample.

Existing magnetic susceptibility is measured pipe 10 as shown in Figure 2, it generally includes elongated canals of stilling 11, body 11 lower end closed, the upper end mouth of pipe 18 for opening wide, the mouth of pipe 18 inner wall shape and pipe covers 12 shape and coincide, for example the mouth of pipe 18 and manage and cover 12 bottoms and be back taper or cylindrical.The inwall of the upper end mouth of pipe 18 of body 11 has frosting 13, frosting 13 cooperates with the frosted layer 14 that pipe covers 12 side faces, sample is packed into behind the body 11, earlier cover 12 mouths of pipe 18 that clog body 11 with managing, both realize preliminary fixing because of frosting 13 cooperates with frosted layer 14, it is tight to lay respectively at

hook

15,16 bolts that body 11 and pipe cover on 12 with bungee then, tangles pipe with rope then and cover suspender 17 on 12 and magnetic susceptibility mensuration is managed 10 be connected on the balance.

But such magnetic susceptibility is measured pipe 10 pipe cover 12 and body 11 need fix with bungee or rope, so operation is comparatively loaded down with trivial details, magnetic susceptibility is measured and is managed 10 use inconvenience.And can't use in the occasion that does not have rope and bungee, its usable range is restricted.

Summary of the invention

The purpose of this utility model just provides a kind of use magnetic susceptibility mensuration pipe more easily.

The scheme that adopts is exactly that a kind of magnetic susceptibility is measured pipe, comprises the body of lower end closed, and the pipe lid that is used for the mouth of pipe of closed tube upper end, is provided for the suspender that is connected with balance pipe cover, and it is characterized in that: described pipe covers and body is threaded.

As seen from the above technical solution, body and Guan Gai that magnetic susceptibility of the present utility model is measured pipe are threaded, and directly both are screwed after sample is packed into so to get final product.And need not to use bungee or rope etc.The use of such magnetic susceptibility mensuration pipe is convenient, and has avoided bungee or the discarded after stain environment of rope.

Embodiment

Magnetic susceptibility shown in Fig. 3,4,5 is measured pipe 10, and magnetic susceptibility mensuration pipe 10 is used for the splendid attire sample and then the magnetic susceptibility of sample is measured.Magnetic susceptibility is measured the body 11 that pipe 10 comprises lower end closed, and be used to seal the pipe cap 12 that magnetic susceptibility is measured the upper end mouth of pipe 18 of pipe 10, pipe covers the suspender 17 that setting is connected with balance on 12, suspender 17 can be suspension ring shown in Figure 3, or be the suspension hook of serpentine shown in Fig. 4,5, preferably suspender 17 is fixed in pipe and covers 12 upper end, is convenient to connecting rope.Tying down suspender 17 with rope during use can be connected to whole magnetic susceptibility mensuration pipe 10 on the balance.Body 11 can not separate with pipe cap 12 and drop during for warranty test, and the mouth of pipe 18 and the pipe cap 12 of body 11 must reliably be connected, and the utility model is on the wall of the mouth of pipe 18 and the screw thread of mutual coupling is set on the wall of pipe cap 12, and body 11 is threaded with pipe cap 12.

Concrete set-up mode as for screw thread mainly contains two kinds, and the one, the mouth of pipe 18 outer walls are provided with external thread, and described pipe lid 12 is the tubulose of upper end closed, the internal thread that the external thread on its inwall setting and the body 11 coincide.The internal diameter unanimity of whole body 11 like this is convenient to sample and is added swimmingly.Preferably the radial dimension of the mouth of pipe 18 is less than the radial dimension of the pipe shaft section of body 11, the radial dimension that the externally threaded mouth of pipe 18 part radial dimensions are slightly less than the body 11 of its below just is set, accordingly, equal or be slightly larger than the external diameter of the pipe shaft section of body 11 with the external diameter of the pipe of the mouth of pipe 18 threaded engagement lid 12.The size of pipe cap 12 be can suitably reduce like this, the body 11 of manufacturing and the material cost of pipe cap 12 saved.

The perhaps described mouth of pipe 18 inwalls are provided with internal thread, and described pipe lid 12 is columniform plug shape, the external thread that the internal thread on its side face setting and the body 11 coincide.Such pipe cap 12 size minimums, material cost is minimum.

Further, can circumferentially engrave indentation 19 in body 11 outer wall upper edges, indentation 19 is positioned at the lower position place of the mouth of pipe 18 of body 11, just indentation 19 is positioned at the upper end of the pipe shaft section of body 11, the amount of each like this sample of packing into can be determined with reference to indentation 19, saved the operation of each weighing sample, further convenient test operation; Certainly, such indentation 19 also can be provided with a plurality of as the scale of test tube.

The body 11 of magnetic susceptibility mensuration pipe 10 and pipe cover 12 and are threaded, and directly both being screwed after sample is packed into so can be fixing reliably with both.And need not to use bungee or rope etc.It is convenient that such magnetic susceptibility is measured the use of pipe, and avoided being worn or destroy and discarded bungee or rope are difficult to degradation treatment and environment is polluted.

Need to prove: the utility model is defined as the upper end with an end of the mouth of pipe 18 of body 11 for convenience of description, blind end is defined as the lower end, above-below direction when just magnetic susceptibility is measured pipe 10 user modes, this above-below direction is not the qualification to this body structure of the utility model; Simultaneously for the ease of the shape of observation tube lid 12 with the mouth of pipe 18, pipe cover 12 do not have yet as user mode screw on the mouth of pipe 18.And such sample hose 10 also can be used for other test, uses and be not limited in the magnetic susceptibility determination test.
