Problems solved by technology
[0003] In the actual operation process, there are many inconveniences for the above two installation structures of argon gas cylinders. For the built-in type, it is obviously very troublesome to install the argon gas cylinder, and the shell needs to be disassembled; for the above plug-in type, There are different technical problems depending on the position of the joint. When the joint is close to the installation hole, most of the argon cylinder is exposed, resulting in a larger volume of the spectrometer. When the joint is far from the installation hole, the tightening process is difficult to implement after inserting the argon cylinder. , and even need to configure special tools to tighten the argon cylinder, so the current installation structure of the argon cylinder is very inconvenient during use

Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as Figure 1 ~ Figure 4 As shown, the argon gas bottle installation structure of the handheld laser-induced breakdown spectrometer includes a spectrometer housing 1, which includes a handle 101 and a machine compartment 102 above the handle 101. A line along the spectrometer is arranged in the machine compartment 102. The slide rail 2 extending in the front and back direction of the housing 1 is slidably connected with a slider 3 which can slide along the length direction of the slide rail 2. The slider 3 is connected with a mounting frame 4, and the mounting frame 4 There is a joint 6 for connecting the argon cylinder 5 and the internal gas circuit of the housing 1. The joint 6 is provided with a threaded hole. For the mounting hole 7, the argon cylinder 5 is inserted into the machine compartment 102 from the mounting hole 7 and ...

The invention relates to an argon cylinder mounting structure of a hand-held laser induced breakdown spectrometer. The argon cylinder mounting structure comprises a spectrometer shell, the shell comprises a grab handle and a machine bin, a sliding rail is arranged in the machine bin, a slider is in sliding connection to the sliding rail, a mounting bracket is connected to the slider, a joint is connected to the mounting bracket, a threaded hole is formed in the joint, a mounting hole right facing the threaded hole of the joint is formed in the position, located at one end of the sliding rail,of the shell, and the argon cylinder is inserted into the machine bin from the mounting hole and is in threaded connection with the threaded hole of the joint. The joint is arranged to be capable of sliding, when the argon cylinder needs to be removed or installed, the argon cylinder is pulled out from the mounting hole outwards, and therefore the argon cylinder can be held with the hand, and theargon cylinder can be removed from the joint. Similarly, when installation is required, the joint is firstly moved to the mounting hole, then the argon cylinder is in threaded connection with the joint, and then the argon cylinder is pushed into the machine bin. According to the technical scheme, disassembly and assembly of the argon cylinder are facilitated, and the volume of the spectrometer cannot be increased.
Description
Technical field: [0001] The invention relates to an installation structure of an argon gas bottle of a hand-held laser-induced breakdown spectrometer. Background technique: [0002] The handheld laser-induced breakdown spectrometer is usually equipped with an argon gas bottle, which is used to supply argon gas to the detection area to improve detection accuracy. There are generally two ways to install the argon cylinder, one is the built-in type, which needs to be disassembled when installing and disassembling the spectrometer shell, and the other is the plug-in type, that is, a mounting hole is opened on the shell, and then A joint for connecting the gas cylinder is arranged inside, and this joint is connected with the internal gas path of the spectrometer, and the argon gas cylinder is inserted into the shell from the installation hole, and is threadedly connected with the joint. [0003] In the actual operation process, there are many inconveniences for the above two ins...
