Abstract
The utility model relates to the technique field of an optical spectrum analyzer, in particular to a sample frame. A sample shelf (1) of the utility model is a column structure whose cross-section takes rectangle shape, a pair of opposite lateral surfaces of the column structure is respectively provided with an exit light window surface (3) and an incident light window surface (5) which is used as a positioning datum plane (4), and a resilient member (2) is arranged on the exit light window surface (3) of the other side. The sample frame of the utility model has the advantages of simple structure and convenient usage, and particularly is an integration sample shelf with reasonable and accurate position, resistant corrosion of strong acids and alkali.
Description
Technical field
The utility model relates to the spectrometric instrument technical field, is specifically related to a kind of specimen holder.
Background technology
In absorption analytical instrument, the manufacturing accuracy and the localization method of specimen holder depended in the location in absorption of sample pond, and it relates to the angle of incident light and emergent light and the length of optical path, and small difference can be to the measuring accuracy generation significant impact of instrument.
In the prior art, general design is that the inner chamber of specimen holder is made the rectangular column structure of an xsect by the absorption cell external diameter, cylinder a light inlet window is respectively established in the side.Then, in adjacent two sides an elastic sheet metal is installed respectively, be convenient to the insertion and the taking-up of absorption cell, such positioning reference will make the location crooked as the absorption cell angle square of leaning to one side not itself, in addition because elastic sheet metal and securing member etc. often are subjected to the corrosion of strong acid, the highly basic effect of can following the string.
Summary of the invention
The purpose of this utility model is that the specimen holder in the existing sample chamber is improved, and a kind of novel specimen holder is provided, and it is that a kind of location is rationally accurate, and dead metal sheet etc. is as the corrosion resistant type integral structure specimen holder of setting element.
According to the professional requirement that absorption cell is made, the utility model considers that should be feasible if adopt the transparent surface of two correspondences of absorption cell as the reference field of location.By this imagination, the utility model as positioning reference plane, is provided with an elastic component with an incident optical window face in the specimen holder on opposite side outgoing optical window face, just can make absorption cell insert specimen holder after, can not produce position change and crooked.
The utlity model has corrosion resistance for making, the utility model also can further adopt engineering plastics die casting, and specimen holder and elastic component are designed to a disjunctor.
For overcoming the unfavorable factor that draw taper is brought, the utility model also can adopt the method for split hot repressing moulding, thereby guarantees the verticality of specimen holder reference field and specimen holder base.
The specimen holder that the utility model provides is simple in structure, and is easy to use, and it is a kind ofly to have the location rationally accurately, and the integral structure specimen holder of anti-strong acid, alkali corrosion.
Below, describe details and working condition in conjunction with the accompanying drawings and embodiments in detail according to the concrete device that the utility model proposes.
Description of drawings
Fig. 1 is a cross-sectional profile structural representation of the present utility model.
Fig. 2 is a longitudinal section of the present utility model cross-sectional view.
Embodiment
Shown in accompanying drawing 1-2, the utility model embodiment provides a kind of specimen holder 1 to be the rectangular column structure of xsect, cylinder the side respectively is provided with an outgoing optical window face 3 and an incident optical window face 5, its with incident optical window face 5 as positioning reference plane 4, on the outgoing optical window face 3 of opposite side, an elastic component 2 is set, described elastic component 2 can be sheet or list structure, its fundamental purpose is fixed absorption cell exactly, like this, after the utility model just can guarantee to make absorption cell to insert specimen holder, can not produce position change and crooked.
And the utility model provides a kind of specimen holder 1 can make conjoined structure, promptly is designed to bigeminy, three or concatermer structure such as tetrad, can more effectively detect like this.
The utlity model has corrosion resistance in order to make, a kind of specimen holder 1 that the utility model provides also can adopt engineering plastics die casting, and specimen holder 1 and elastic component 2 are made a plasticity conjoined structure.
For overcoming the unfavorable factor that draw taper is brought, the utility model also can adopt the method for split hot repressing moulding, thereby guarantees the mutual vertical of specimen holder reference field 4 and specimen holder 1 base.
