Description

Technical Field

[0001] The utility model relates to the technical field of spectrometer sample measurement positioning, in particular to a direct-reading spectrometer sample pressing rack. Background Art

[0002] A spectrometer is a device that uses photomultiplier tubes and other light detectors to measure the intensity of spectral lines at different wavelengths. It uses dispersion elements to separate the electromagnetic radiation of the radiation source into the required wavelengths or wavelength regions, and measures the intensity at the selected wavelength (or scans a certain band). Before measurement, a sample fixture is required.

[0003] In the prior art, devices for sample positioning often require a power device to drive the sample pressing structure to bear force to press and position the sample, for example, using driving energy such as gas energy, electric energy, or using spring restraint to apply pressure on the sample; the method of using driving energy such as gas energy, electric energy, etc. to apply pressure requires the use of corresponding supporting equipment, which is complicated to operate and has high application costs; the method of using spring restraint to apply pressure has the problem that the spring is easily worn and the pressure contact effect decreases as the spring performance decreases, affecting the pressure contact positioning effect of the sample. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a sample pressing rack for a direct reading spectrometer, which is used to solve the problems of cumbersome operation and high cost of the sample fixing device used in the prior art.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a direct reading spectrometer sample pressing rack, including a measuring table, a measuring hole is provided on the measuring table, and the sample pressing rack is matched on the measuring table;

[0006] The sample pressing rack comprises a slide seat mounted on the side end of the measuring table, the slide seat is equipped with a slide rod that can be lifted and slid, the upper end of the slide rod is provided with a bracket, and the front end of the bracket extends to the top of the measuring table;

[0007] A sample pressing head is arranged on the front end of the bracket, and the slide bar slides downward in the slide seat by gravity to drive the bracket to fall freely, thereby driving the sample pressing head to press down into the sample measuring hole to press and locate the sample.

[0008] In one embodiment of the utility model, a slide groove is provided at the side end of the slide seat, and a ball head slider is provided at the side end of the slide rod. The ball head slider slides into the slide groove to position the verticality of the slide rod relative to the slide seat.

[0009] In one embodiment of the utility model, the measuring platform is equipped with a pressing plate for protecting the sample testing hole; a through hole intersecting the sample testing hole is arranged on the pressing plate, and the through hole corresponds to the bottom of the sample pressing head.

[0010] In an embodiment of the present invention, the diameter of the through hole is smaller than the diameter of the sample testing hole and larger than the diameter of the sample pressing head.

[0011] In an embodiment of the present invention, the length of the sample pressing head is greater than the sum of the depths of the sample testing hole and the through hole.

[0012] As described above, the sample pressing rack for direct-reading spectrometer of the utility model has the following beneficial effects:

[0013] 1. By setting up a sample pressing rack that matches the measuring table, when in use, you only need to pull up the slide bar, and the sample pressing rack can use the weight of the slide bar to lift and slide in the slide seat, driving the sample pressing head set on the slide bar through the bracket to naturally slide down and fall into the sample measuring hole, so that the sample is fixed in a pressure-touch manner. The sample pressing rack is easy to operate and use, which is conducive to the direct reading spectrometer to reliably detect the sample;

[0014] 2. By arranging a slide groove on the slide seat and arranging a ball head slider that slides into the slide groove on the slide rod, the ball head slider can provide a vertical and sliding positioning function along the slide groove when the slide rod is lifted and slid relative to the slide seat, thereby ensuring the accuracy of the sample pressing and positioning of the sample pressing rack;

[0015] 3. The utility model has a simple design and is easy to use. It only requires a manual pulling action to achieve reliable pressure-touch positioning of the sample. No gas, electricity or other driving energy is required. The operation is simple and the application cost can be reduced. There is no need to use consumable auxiliary facilities such as springs. The failure rate is low and the performance is stable during use. The pressure-touch positioning of the sample is more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The measuring table 1 is equipped with a pressing plate 2 for protecting the sampling hole 11; the pressing plate 2 is provided with a through hole 21 intersecting the sampling hole 11, and the through hole 21 corresponds to the bottom of the pressing head 6; the diameter of the through hole 21 is smaller than the diameter of the sampling hole 11 and larger than the diameter of the pressing head 6, so as to ensure that the pressing head 6 can smoothly fall into the sampling hole 11 and provide better protection for the sampling hole 11.

[0025] The length of the sample pressing head 6 is greater than the sum of the depths of the sample measuring hole 11 and the through hole 21. In the actual sample measuring process of the direct reading spectrometer, the heights of the samples are not the same. Setting a longer sample pressing head 6 can be suitable for sample detection and positioning of multiple specifications, with a wide range of applications and high practicality.
