Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spectrometers, in particular to a portable spectrometer. Background Art
[0002] Portable spectrometer, also known as handheld spectrometer, is a spectral analysis instrument based on XRF spectral analysis technology. It is mainly composed of X-ray tube, detector, CPU and memory. Due to its portability, high efficiency, portability and accuracy, it has important applications in alloys, ores, environment, consumer products and other fields. When high-energy X-rays with energy higher than the binding energy of the inner electrons of atoms collide with atoms, an inner electron is expelled, resulting in a, which makes the entire atomic system unstable. When the outer electron jumps to the hole, a photoelectron is generated. The ejected photon may be absorbed again and expel another secondary photoelectron in the outer layer, which is also called secondary photoelectric effect or non-radiative effect. The ejected secondary photoelectron is called Auger electron. When the outer electron jumps into the inner hole, the energy released is not absorbed by the atom, but is released in the form of photons, which produces X-ray fluorescence, whose energy is equal to the energy difference between the two energy levels. Therefore, the energy or wavelength of X-ray fluorescence is characteristic and has a one-to-one correspondence with the element. According to Moseley's law, as long as the wavelength of fluorescent X-rays is measured, the type of element can be known, which is the basis of fluorescent X-ray qualitative analysis. In addition, there is a certain relationship between the intensity of fluorescent X-rays and the content of the corresponding elements, based on which quantitative element analysis can be performed. The X-ray detector converts the optical signal of the characteristic spectrum line of the X-ray of the sample element into an easily measurable electrical signal to obtain the characteristic information of the element to be measured.
[0003] At present, when using the portable spectrometers on the market, the user is required to hold the operating handle to move the detection head on the portable spectrometer. In actual use, when the user holds the operating handle to move the detection head on the portable spectrometer, due to the different sizes of users' palms, and the size of the operating handle of the portable spectrometer is a fixed value, when the user's palm is too large or too small, it will be inconvenient for the user to hold the operating handle, thereby affecting the user's experience.

[0024] In a preferred embodiment, a stabilizing plate 12 is fixedly connected to the outer wall of the rotating rod 11, a threaded rod 13 runs through the inside of the stabilizing plate 12, and the threaded rod 13 is connected to the stabilizing plate 12 by threads. When the rotating rod 11 moves, the rotating rod 11 can drive the stabilizing plate 12 to move in a circle, so that the stabilizing plate 12 can drive the threaded rod 13 to move in a circle.
[0025] In a preferred embodiment, a positioning hole 14 is opened at the bottom of the operating handle 3, and the top end of the threaded rod 13 is slidably connected to the positioning hole 14. When the threaded rod 13 moves, the threaded rod 13 can rotate with the stabilizing plate 12, and at the same time, one end of the threaded rod 13 is separated from the positioning hole 14.
[0026] In a preferred embodiment, a fixed block 15 is fixedly connected to the bottom end of the detection head 1, a mounting groove 16 is opened at the bottom end of the fixed block 15, and a mounting block 17 is fixedly connected to the top of the operating handle 3.

[0027] The working principle of the utility model is as follows: when the device is used, the operating handle 3 will be adjusted to a smaller size during production. When it is necessary to adjust it according to the size of the user's palm, it is only necessary to adjust the distance that the adjusting plate 6 is moved out of the groove 4, and the threaded rod 13 is rotated to make the threaded rod 13 and the stabilizing plate 12 move through the thread phase, so that one end of the threaded rod 13 can be moved out of the positioning groove.

When the fixing block 15 drives the mounting groove 16 to move, the second contact 19 inside the mounting groove 16 will be separated from the first contact 18 on the outer wall of the mounting block 17.
[0029] In a preferred embodiment, a bolt 20 is provided on the outer wall of the fixing block 15, one end of the bolt 20 passes through the interior of the mounting groove 16 and the bolt 20 is connected to the fixing block 15 by a thread, and a snap-fit groove 21 is provided on the outer wall of the mounting block 17, one end of the bolt 20 is slidably connected to the snap-fit groove 21, when the bolt 20 moves, the bolt 20 will move with the fixing block 15 through the thread, and at the same time, one end of the bolt 20 will move inside the mounting groove 16, causing one end of the bolt 20 to separate from the snap-fit groove 21.
[0030] The working principle of the utility model is as follows: when the detection head 1 needs to be disassembled and repaired, the bolt 20 is rotated at this time, so that the bolt 20 and the fixing block 15 move through the thread, and at the same time, one end of the bolt 20 will rotate inside the mounting groove 16, so that the one end of the bolt 20 will slowly separate from the engaging groove 21. When one end of the bolt 20 is completely separated from the engaging groove 21, the operating handle 3 can be pulled at this time, so that the operating handle 3 drives the mounting block 17 to move, so that the mounting block 17 is moved out from the mounting groove 16, so that the second contact 19 inside the mounting groove 16 is separated from the first contact 18 on the mounting block 17, thereby making it convenient to disassemble and repair the detection head 1.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
