The magnetic susceptibility pipe

Technical field

The present invention relates to be used in the chemical experiment hold the glass container of sample.

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, and 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 through the reading of balance.Testing crew changes the related parameter that has that just can grasp the test of sample magnetic susceptibility through the reading of balance, and then calculates the magnetic susceptibility of sample.

It is as shown in Figure 2 that existing magnetic susceptibility is measured pipe 10; It generally includes elongated canals of stilling 11; Body 11 lower end closed, the mouth of pipe 18 of upper end for opening wide, the shape of the mouth of pipe 18 inner wall shape and pipe close 12 is coincide, and for example the mouth of pipe 18 is back taper or cylindrical with pipe close 12 bottoms.The inwall of the upper end mouth of pipe 18 of body 11 has frosting 13; Frosting 13 cooperates with the frosted layer 14 of pipe close 12 side faces; Sample is packed into behind the body 11, clogs the mouth of pipe 18 of body 11 earlier with pipe close 12, and both tentatively fix because of frosting 13 cooperates realization with frosted layer 14; Hook 15,16 bolts that will lay respectively on body 11 and the pipe close 12 with bungee then are tight, and the suspender 17 that tangles on the pipe close 12 with rope then is connected to magnetic susceptibility mensuration pipe 10 on the balance.

But such magnetic susceptibility pipe 10 is because pipe close 12 need be fixed with bungee or rope with body 11, so operation is comparatively loaded down with trivial details, the use of magnetic susceptibility pipe 10 is inconvenient.And can't use in the occasion that does not have rope and bungee, its usable range is restricted.

Summary of the invention

The object of the invention just provides a kind of use magnetic susceptibility pipe more easily.

The scheme that adopts is exactly a kind of magnetic susceptibility pipe; The body that comprises lower end closed; And the pipe close that is used for the upper end mouth of pipe of closed tube; Be provided for the suspender that is connected with balance on the pipe close, it is characterized in that: described pipe close is processed by the elastic anti-slip material, and the pipe close and the mouth of pipe are pegged graft and also constituted interference fit.

Visible by technique scheme, the mouth of pipe and the pipe close of magnetic susceptibility pipe of the present invention are pegged graft, and pipe close and mouth of pipe formation interference fit; So can guarantee both firm and reliable connection; Because pipe close is to have necessarily flexiblely, can pipe close be extracted from the mouth of pipe so, and both are separated.Such magnetic susceptibility pipe need not to use fixedly body and pipe close such as bungee or rope, so its use is convenient, and has avoided bungee or the discarded after stain environment of rope.

Embodiment

Like Fig. 3,4, the magnetic susceptibility pipe 10 shown in 5, magnetic susceptibility pipe 10 is used for the splendid attire sample and then the magnetic susceptibility of sample is measured.Magnetic susceptibility pipe 10 comprises the body 11 of lower end closed; And the pipe close 12 that is used to seal the upper end mouth of pipe 18 of magnetic susceptibility pipe 10; The suspender 17 be connected with balance is set on the pipe close 12, and suspender 17 can be Fig. 3, the suspension ring shown in 4, or shown in Figure 5 be the suspension hook of serpentine; Preferably suspender 17 is fixed in the upper surface of pipe close 12, is convenient to connecting rope.Tying down suspender 17 with rope during use can be connected to whole magnetic susceptibility pipe 10 on the balance.Body 11 can not separate with pipe close 12 and drop during for warranty test; The mouth of pipe 18 and the pipe close 12 of body 11 must reliably be connected; Pipe close 12 of the present invention is processed by the elastic anti-slip material of silica gel or rubber or plastics class, and pipe close 12 is pegged graft with the mouth of pipe 18 and constituted interference fit.

Such interference fit mainly contains dual mode; The first mouth of pipe 18 is and the isometrical cylindrical shape of the pipe shaft section of body 11; Pipe close 12 is the pipe box shape of upper end closed, and the internal diameter of pipe close 12 is diminished to top by the lower end gradually, can claim that also pipe close 12 is slightly uncovered lid shapes; The external diameter of the mouth of pipe 18 is substantially equal to the internal diameter at the inner chamber middle part of pipe close 12, and the mouth of pipe 18 is plugged on the inner chamber of pipe close 12 like this.In the structure of this mode pipe close 12 easily by last with pull up.

Perhaps pipe close 12 is the plug shape, and the mouth of pipe 18 can be cylindrical shape or also can be infundibulate shown in Figure 3 this moment, and pipe close 12 is plugged in the mouth of pipe 18.The size of pipe close can be less in such structure; Can save material cost, especially the mouth of pipe 18 is funnel shaped structure, and just the mouth of pipe 18 comprises the top that back taper is tubular and the bottom of straight tube shape; The straight length size of the size of straight length and body 11 is coincide; In other words just the straight length of the mouth of pipe 18 and body 11 is the funnelform integral body that is of whole processing, and the back taper pipeline section of the mouth of pipe 18 is convenient to packing into of sample like this, and is unrestrained when avoiding sample to pack into.Certainly this moment, pipe close 12 preferably was exactly to be plugged on the bottom that pipe close 12 is plugged on the straight length top of body 11 or is called the infundibulate mouth of pipe 18.This moment, not only sample was packed into easily, and pipe close 12 volumes are still very little, not only easy to use but also cost of idleness not.

In order to further facilitate the use of magnetic susceptibility pipe 10; Pipe close 12 preferably has sufficient length, is exactly that stretch out outside the mouth of pipe 18 pipe close 12 upper ends usually, is convenient to plug pipe close 12 like this; And the pipe close external diameter also can be to be tapered from top to bottom; Make 1/3 length of pipe close 12 bottoms insert the bottom of the mouth of pipe 18, so both guaranteed both firm plug, avoid insertion not to be drawn out easily deeply very much again.Can also convex epirelief circumferentially be set in the outer wall upper edge of pipe close 12 bottoms; The best zigzag shape of convex epirelief is extended upward by the lower end along the side face of pipe close 12; When pipe close 12 inserts the mouth of pipe 18 like this; Mainly be that the convex epirelief of continuous multi-layer spiral is squeezed and is out of shape, its elastic deformation and acting force guarantee that both grafting are more firm, and the operation of plug pipe close 12 is still very convenient.

Further, can circumferentially engrave indentation 19 in body 11 outer wall upper edges, indentation 19 is used to identify the addition of sample, is convenient to the sample that testing crew all adds same amount at every turn and makes an experiment.Indentation 19 can similar test tube scale equally be provided with; Also can just be positioned at of binding site place of straight length and 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 confirmed with reference to indentation 19, the operation of having saved each weighing sample, further convenient test operation.

The mouth of pipe and the pipe close of magnetic susceptibility pipe of the present invention are pegged graft; And the pipe close and the mouth of pipe constitute interference fit; So can guarantee both firm and reliable connection; Because pipe close is to have certain flexible anti-slip material, both can not only be connected firmly and pipe close 12 also can be extracted in the mouth of pipe 18 easily so.Such magnetic susceptibility pipe need not to use fixedly body 10 and pipe close 12 such as bungee or rope, so its use is convenient, and has avoided bungee or the discarded after stain environment of rope.

Need to prove: the present invention is defined as the upper end for an end of describing the convenient mouth of pipe 18 with body 11, and blind end is defined as the lower end, the above-below direction during magnetic susceptibility pipe 10 user modes just, and this above-below direction is not the qualification to this body structure of the present invention; Simultaneously for the ease of observing the shape of pipe close 12 and the mouth of pipe 18, pipe close 12 also not 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.
