Abstract
The utility model discloses a special analysis fixture of a glow discharge spectrometer, which includes a base (1), an ejecting block (2), a spring (3) and a sealing ring (4); a blind hole (5) is formed at the center of the base (1), one end of the spring (3) is connected with the ejecting block (2), and the other end is connected with the bottom of the blind hole (5); the spring (3) and the ejecting block (2) connected with the spring (3) are mounted in the blind hole (5) of the base (1); a sealing ring (4) is arranged on the end surface of the base (1) at the opening end of the blind hole (5); a centering structure is arranged on the top surface of the ejecting block (2) and adopts a calibrated cross curve passing the center of the top surface; and the calibration distance is 0.5 mm. The analysis fixture adopting the structure has the advantages of simple structure, and convenient and reliable use, and enables small samples to be excited normally.
Description
Technical field
The utility model relates to a kind of glow discharge spectrometry dedicated analysis anchor clamps.
Background technology
Glow discharge spectrometry is a kind of advanced instrument that is used for analysis of metallic materials chemical constitution, metal surface thickness of coating and coating chemical constitution, the characteristics of this instrument are that the solid block sample is directly analyzed, need not the chemical solution sample handles, but it has certain requirement to the size and dimension of sample, be that sample must have a diameter or the length of side greater than the plane domain of 14mm, make sample can cover the O-ring seal of glow-discharge lamp fully.But in actual use, many samples all can not satisfy condition, thereby have also just limited the scope of application of glow discharge spectrometry.
China utility model instructions ZL 200420109246.4 discloses a kind of glow discharge spectrometry dedicated analysis anchor clamps, comprise pedestal, jacking block, spring and O-ring seal, blind hole is set in the pedestal, spring and the jacking block that links to each other with spring are installed in the blind hole of pedestal, on the pedestal end face of blind hole openend O-ring seal are set.This analysis anchor clamps can be reduced to the analyzable sample size specification of glow discharge spectrometry about 7mm, have advantage simple in structure, easy to use.But this analysis anchor clamps can not accurately be placed on small sample the center of jacking block end face, with regard to causing the center of departing from the jacking block end face because of small sample that small sample can not normally be excited easily, make test result inaccurate like this.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, easy to use and reliable and glow discharge spectrometry dedicated analysis anchor clamps that small sample is normally excited are provided.
For solving the problems of the technologies described above, the utility model glow discharge spectrometry dedicated analysis anchor clamps are made of pedestal, jacking block, spring and O-ring seal, blind hole is set in the pedestal, one end of spring links to each other with jacking block, the other end is connected with the blind hole bottom, and spring and jacking block are installed in the blind hole of pedestal, on the pedestal end face of blind hole openend O-ring seal are set, the end face of described jacking block is provided with the structure that centers, and the described structure that centers is at least two straight lines by the end face center band scale of jacking block.
The described structure that centers can be the cross curve of the end face center band scale by jacking block; The described structure that centers also can be four straight lines by end face center band scale, and the angle between the straight line is 45 °; The scale spacing of the straight line of further described band scale is 0.5mm.
By increasing the structure that centers to analyzing anchor clamps, make small sample can accurately be positioned at jacking block end face center, thereby small sample can normally be excited, test result is accurately and reliably, and is particularly particularly evident to diameter or the small sample result of use of the length of side about 7mm.
Description of drawings
Below in conjunction with the drawings and specific embodiments detailed content of the present utility model is described;
Fig. 1 is a glow discharge spectrometry dedicated analysis clamp structure synoptic diagram of the present utility model;
Fig. 2 is that A-A shown in Figure 1 of the present utility model is to the sectional structure synoptic diagram;
In Fig. 1, Fig. 2: 1, pedestal; 2, jacking block; 3, spring; 4, O-ring seal; 5, blind hole.
Embodiment
As Fig. 1 and Fig. 2, the utility model glow discharge spectrometry dedicated analysis anchor clamps comprise pedestal 1, jacking block 2, spring 3 and O-ring seal 4, blind hole 5 is set in the pedestal 1, one end of spring 3 links to each other with jacking block 2, the other end is connected with blind hole 5 bottoms, spring 3 and jacking block 2 are installed in the blind hole 5 of pedestal 1, on pedestal 1 end face of blind hole 5 openends O-ring seal 4 is set, the end face of jacking block 2 is provided with the structure that centers, the described structure that centers is that the scale spacing of cross curve is 0.5mm by the cross curve of the end face center band scale of jacking block 2.The structure that centers of the present utility model can also be four straight lines by the band scale at the end face center of jacking block 2, and the angle between the straight line is 45 °, and the scale spacing of straight line is 0.5mm.
Under user mode, only need accurately are placed on the diameter or the length of side as the cross curve of band scale the end face center of jacking block 2 by the structure example that centers less than the small sample of 14mm, then by the anode port of jacking block 2 roof pressures at glow-discharge lamp, O-ring seal 4 on pedestal 1 end face keeps sealing with operative end surface, can carry out the analytical test operation.
Claims (4)
1. glow discharge spectrometry dedicated analysis anchor clamps, comprise pedestal (1), jacking block (2), spring (3) and O-ring seal (4), blind hole (5) is set in the pedestal (1), one end of spring (3) links to each other with jacking block (2), the other end is connected with blind hole (5) bottom, spring (3) and jacking block (2) are installed in the blind hole (5) of pedestal (1), on pedestal (1) end face of blind hole (5) openend O-ring seal (4) is set, it is characterized in that: the end face of described jacking block (2) is provided with the structure that centers, and the described structure that centers is at least two straight lines by the end face center band scale of jacking block (2).
