Abstract

The utility model provides a positioning mechanism of a radiation type linear sample support, which comprises four U-shaped slots. The four U-shaped slots are arranged on the outer circumference of the round sample support. The utility model has the positive effects that linear samples can be rapidly positioned on the radiation type linear sample support, and the initial positioning time for the linear samples can be reduced.

Description

The detent mechanism of radial pattern wire sample holder

Technical field

The utility model relates to the device of a kind of bearing test with sample, particularly is the detent mechanism of a kind of radial pattern wire sample holder.

Background technology

The X-ray fluorescence spectra analytic approach has favorable reproducibility, and measuring speed is fast, highly sensitive characteristics.Can analyze all elements between F (9)～U (92).Sample can be solid, powder (need be pressed into bulk), liquid, pastel, grease, film etc.Utilize X-ray fluorescence spectra technical Analysis sample to have a lot of advantages, for example: only need on a small quantity or need not specimen preparation, the quick nondestructive analysis, simple to operate, can operate by producers, can not produce detrimental substance.

But up to the present, because the wire sample is difficult for fixing and is shaped, still needleless is to the application of wire sample (for example yarn fabric, suture or the like).Usually we can only become the wire sample bolus one to put into the X-ray fluorescence spectra analyser and measure, and this just makes the state of testing sample be in a kind of uncontrolled random state, thereby causes measuring poor reproducibility, have had a strong impact on the accuracy of measuring.

Therefore, we are badly in need of a kind of suitable carrying wire sample, and can control the state of linear sample fast with the sample positioned holder in the sample holder of wire sample, guarantee the reappearance of measurement, make the X-ray fluorescence spectra analytic approach can be applied in the measurement of wire sample.

The utility model content

The purpose of this utility model is to solve the deficiencies in the prior art, and the detent mechanism of a kind of radial pattern wire sample holder is provided.

In order to solve the realization above-mentioned purpose, the technical solution of the utility model is such.

The detent mechanism of a kind of radial pattern wire sample holder, described detent mechanism is made of 4 U-lags, be located on the excircle of circular sample holder, described first U-lag and second U-lag are positioned at outer circumferential edges in the sample holder, and be on the same diametric(al), described the 3rd U-lag and the 4th U-lag are positioned at outer circumferential edges under the sample holder, and are on the same diametric(al), and described first U-lag lays respectively at the identical position of upper and lower excircle with the 4th U-lag, second U-lag and the 3rd U-lag; U-lag is recessed to the center of circle from circumferential edges.

Good effect of the present utility model is: the wire sample can be positioned at fast in the holder of radial pattern wire sample, shorten the initial alignment time of wire sample.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a front elevation.

Fig. 2 is a vertical view.

Fig. 3 is a perspective view.

Number in the figure is: excircle under excircle, the holder of 6-sample in 1-the first U-lag, 2-the second U-lag, 3-the three U-lag, 4-the four U-lag, the holder of 5-sample.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

The detent mechanism of a kind of radial pattern wire sample holder, as depicted in figs. 1 and 2, described detent mechanism is made of 4 U-lags, be located on the excircle of circular sample holder, described first U-lag 1 and second U-lag 2 are positioned at excircle 5 edges in the sample holder, and be on the same diametric(al), described the 3rd U-lag 3 and the 4th U-lag 4 are positioned at excircle 6 edges under the sample holder, and are on the same diametric(al); U-lag is recessed to the center of circle from circumferential edges.

As shown in figures 1 and 3, described first U-lag 1 lays respectively at the identical position of upper and lower excircle with the 4th U-lag 4, second U-lag 2 and the 3rd U-lag 3.

During use, can be earlier with the wire sample at the center section of radial pattern wire sample holder around a circle and knotting, finish the fixing of wire sample.After fixing, just can begin coiling, the coiling step is: the wire sample is embedded embed first U-lag 1, second U-lag 2, the 3rd U-lag 3 and the 4th U-lag 4 successively, finish the initial alignment of wire sample.Then the wire sample is embedded the groove adjacent and groove corresponding groove on corresponding groove on the diametric(al) and other end therewith, finish one group of coiling with position line.By that analogy, the wire sample is embedded in the remaining groove as stated above successively, finish the coiling work of wire sample.Carrying out X-ray fluorescence spectra when analyzing, only needing the sample that coiling be finished propped up in the sample disc of instrument and get final product.

Good effect of the present utility model is:

1, tested wire sample is in setting, quantitative state, has improved the reappearance and the accuracy of measurement result.

2, keep tested wire sample to be in certain tension state, be beneficial to the collection and the measurement of secondary X fluorescence signal, for trace harmful elements in the measuring samples provides the foundation.

More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
