Abstract
The utility model discloses an angle measuring instrument with an adjustable scan circle for an X ray diffraction instrument. The angle measuring instrument comprises an angle measuring instrument body, a light source part and a detector part. Both the light source part and the detector part are fixedly mounted on the angle measuring instrument body; the light source part comprises a light source, a sliding block and a light source support frame; the light source is fixed on the sliding block; the sliding block can be connected onto the light source support frame in a sliding manner; the detector part comprises a detector, a pressure block and a detector support frame; the detector is fixedly mounted on the pressure block; and the pressure block is movably connected with the detector support frame. In the utility model, the light source part has larger weight and is designed into the combination of a dovetail guide rail and the sliding block, thereby ensuring the position accuracy of the light source and convenient adjustment; the detector part has lighter weight and frequent adjustment, and is manufactured into the combination of a right-angled guide rail and the three-cornered pressure block, thereby ensuring the position accuracy and convenient and frequent adjustment.
Description
Technical field
The utility model relates to a kind of X-ray diffractometer and justifies angular instrument with adjustable scanning.
Background technology
Scattering takes place in x-ray bombardment to crystal, wherein diffraction phenomena is that X ray is by a kind of special performance of crystal scattering.The essential characteristic of crystal is that its micromechanism (arrangement of atom, molecule or ion) has periodically, when X ray was scattered, the coherent scattering ripple identical with the incident wave wavelength in the scattering wave can interfere with each other, on some specific directions, strengthen mutually, produce diffracted ray.The direction that crystal may produce diffraction is decided by the type (structure cell type) and the basic size (interplanar distance, cell parameter etc.) thereof of crystal microscopic structure; And diffracted intensity is decided by the element kind of each composed atom in the crystal and coordinate arranged evenly thereof.The crystal diffraction method is to study the strongest method of crystal structure at present, and powder diffractometer is an equipment of studying the most frequently used and most convenient of the X-ray diffraction of powder crystal at present, and the measurement of angle of diffraction then realizes by the mechanical angular instrument of a precision.The size of scanning circle has determined the resolution and the measured intensity of instrument.When scanning circle increased, the diffracted ray of different directions separated easily, be detected device respectively and accept, thereby the resolution of instrument improves, but light path increases simultaneously, and the X ray enhancing that decays in air is so measured intensity reduces; The scanning circle reduces, and the diffracted ray of different directions is difficult for separately being detected device easily and obscuring, thus the reduction of the resolution of instrument, but light path reduces, and X ray reduces in air, thus measured intensity improves.
The utility model content
The purpose of this utility model provides a kind of X-ray diffractometer with adjustable scanning circle angular instrument, and is simple in structure, easy to use, scans circle greatly, the resolution height of instrument.
For solving the problems of the technologies described above, technical scheme provided by the utility model is: a kind of X-ray diffractometer is justified angular instrument with adjustable scanning, this angular instrument includes angular instrument main body, the Lights section and explorer portion, and described the Lights section and explorer portion all are installed on the angular instrument main body; Described the Lights section includes light source, slide block and light source bracket, and described light source is fixed on the slide block, and described slide block is connected on the light source bracket slidably; Described explorer portion comprises detector, briquetting and detector carriage, and described detector is fixedly mounted on the detector carriage, described briquetting and detector carriage active link.
The adjustment pad is installed between described light source bracket and the slide block.
The advantage that the utlity model has: the Lights section weight is bigger, is designed to the combination of dovetail guide and slide block, can guarantee the positional precision of light source like this, convenient again the adjusting; Explorer portion weight is lighter, regulate frequently, thereby the combination of square up guide rail and triangle briquetting can guarantee positional precision, makes things convenient for frequent adjustment again.
