Description
Technical field
The present invention relates to the adjustable specimen holder of a kind of XRD.
Background technology
XRD (X-ray diffractometer, X-ray diffraction are called for short XRD), is the X-ray diffraction utilizing Crystallization, carries out the structure analysis method of interior atoms at spatial distribution state to material.By there is certain wavelength x-ray bombardment to crystal material time, X ray because running into regularly arranged atom or ion and scattering occurring in crystallization, the X ray of scattering in a certain direction phase place is strengthened, thus the distinctive diffraction phenomena that display is corresponding with crystalline texture.The advantage such as bulk information that method of X-ray diffraction has not lesioned sample, pollution-free, quick, measuring accuracy is high, can obtain about crystal perfection.
But X-ray diffractometer is when sample test, and because in specimen holder, sample cell is excessive, the requirement making paired samples is very large.But scientific research and testing ordinary test amount is less, often cause sample detection quantity not sufficient, prohibited data detection is true.Moreover smooth bottom micro-example frame, when specimen holder is in rotation detected state, detection material easily landing from sample cell, prohibited data detection is true.Finally, the content detecting ceramic surface is, the general plasticine that adopts is used for potsherd to adhere in sample cell, and easily come off, surface is uneven with specimen holder, and prohibited data detection is true.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency how overcoming prior art existence, provides the adjustable specimen holder of a kind of XRD, can measure per sample and regulate medicine groove, and can detect thing by fixed solid, accuracy increases.
Technical solution of the present invention is: the adjustable specimen holder of a kind of XRD, comprises specimen holder body, and described specimen holder body central position is provided with sample cell.The present invention also comprises bolt, backstay, described sample cell runs through up and down, screw thread is provided with in described sample cell, described bolt is fixed on below described sample cell by screw thread, described bolt is moved up and down in described sample cell by screw thread, described specimen holder body is provided with from edge to the pipeline that sample cell laterally runs through, described backstay is positioned at pipeline, described backstay comprises top flat, spring and pull bar, described top flat card and in pipeline inner termination, described top flat and described sample cell inwall match, described topsheet surface composition groove inwall, described top flat rear end is provided with spring, described top flat can be stretched in sample cell by spring, the rear end of described spring is fixed on pull bar, the described pull bar other end stretches out specimen holder, and this is external, described pull bar is by several protruding fixing cards with on specimen holder body.
As preferably: described pipeline is two, and described backstay is two, described two pipelines be 180 ° symmetrical.
As preferably: described pipeline is four, and described backstay is four, and described two pipeline enclosures are every 90 ° of distributions.
The present invention adopts bolt to be arranged on the below of sample cell, achieves moving up and down of bolt, thus regulates the charging capacity of sample cell, to adapt to the sample detection of different amount.The backstay of the uniqueness be originally provided with, solid can be helped to detect thing and be fixed in sample cell, adopt the backstay of at least two, twin fixed guide-vane solid detects thing, such as pottery, sheet metal etc.The present invention designs uniqueness, is skillfully constructed, simple and practical, X-ray diffraction is detected there is substantial effect and great meaning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the adjustable specimen holder structural representation of a kind of XRD disclosed by the invention;
Embodiment
Referring to accompanying drawing, describe the adjustable specimen holder of a kind of XRD of the present invention in detail.
The adjustable specimen holder of a kind of XRD, comprise specimen holder body 1, described specimen holder body 1 centre is provided with sample cell 11.As shown in Figure 1, bolt 12, backstay 13 are installed in sample cell 11, bolt 12 from sample cell 11 from run through from above, screw thread is provided with in described sample cell 11, described bolt 12 is fixed on below described sample cell 11 by screw thread, described bolt 12 is moved up and down in described sample cell 11 by screw thread, and this process implementation depth of sample cell 11, adapting to the sample of different detection limit.
For further fixed solid sample is as porcelain, sheet metal, described specimen holder body 1 is provided with from edge to the pipeline that sample cell 11 laterally runs through, described backstay 13 is positioned at pipeline, described backstay 13 comprises top flat 131, spring 132 and pull bar 133, described top flat 131 blocks and in pipeline inner termination, described top flat 131 matches with described sample cell 11 inwall, described top flat 131 surface composition groove inwall, described top flat 131 rear end is provided with spring 132, described top flat 131 can stretch in sample cell 11 by spring 132, the rear end of described spring 132 is fixed on pull bar 133, described pull bar 133 other end stretches out outside specimen holder body 1, described pull bar 133 is by the fixing card of several protruding a with on specimen holder body.
Described pipeline 14 is two, and in described backstay, 13 is two, and described two pipelines 14 are symmetrical in 180 °, twin fixed guide-vane.
When the present invention uses, sample is loaded in sample cell 11, swivel bolt 12, bolt 12 moves from bottom to top, and sample cell 11 is more and more shallow, until sample flushes with specimen holder body 1, sample surfaces is flattened, specimen holder body 1 is put into XRD diffractometer, detects.
When needs detect solid metal sheet, sheet metal is put into sample cell 11, swivel bolt 12, bolt 12 moves from bottom to top, sample cell 11 is more and more shallow, until sheet metal flushes with specimen holder body 1, the pull bar 133 of both sides is firmly inwardly pushed, top flat 131 stretches out outside pipeline by the spring 132 of rear end and the thrust of pull bar 133, top flat 131 ensures to withstand sheet metal, the top flat 131 of the other end also withstands sheet metal simultaneously, ensure sheet metal twin fixed guide-vane, protruding a blocks pull bar 133, ensure the state withstood, specimen holder is put into XRD diffractometer, detect.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to embodiment illustrated herein, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
