[0002] Direct-reading spectrometers, widely used in materials analysis and quality inspection, are commonly employed in metallurgy, casting, and machinery manufacturing to achieve rapid quantitative detection of metallic elemental composition. To improve detection efficiency and adaptability to different environments, mobile direct-reading spectrometers are becoming an important direction for technological development. These devices typically integrate a display module, a power module, and a gas cylinder holder for gas-assisted detection to meet application needs in various testing environments.

[0003] In existing technologies, the argon cylinder support for mobile direct-reading spectrometers mostly uses traditional mechanical connection structures for installation and disassembly. Common methods include bolt tightening, slot fitting, or external tool-assisted installation. In practical applications, this type of structure is generally assembled and disassembled with the assistance of mechanical tools (such as wrenches and screwdrivers). Although the structure has a certain degree of reliability, it suffers from cumbersome operating procedures and low efficiency in terms of rapid assembly and disassembly and on-site replacement, and it also requires a certain level of skill from the operators.

[0004] However, in the existing technology, when connecting the spectrometer to the argon cylinder support, additional tools are usually required for fixing. This operation is complicated and time-consuming, which is not conducive to rapid deployment and flexible use, especially in the field testing environment. It is also not easy to achieve modular rapid assembly, which affects the overall convenience and operational efficiency of the spectrometer and makes it difficult to meet the requirements of mobile operation for rapid deployment and high efficiency.

[0009] The limiting component includes a limiting ring, which is fixedly connected to the outer wall of the connecting pin, and one side of the limiting ring is in contact with the outer wall of the connecting plate.

[0010] As a further description of the above technical solution:

[0011] The top of the machine body is fixedly connected to a shell, and a limit groove is formed inside the shell.

[0012] As a further description of the above technical solution:

[0013] An adjustment ring is fixedly connected to the bottom of the display screen. One end of the adjustment ring is rotatably connected inside the limiting groove, and a positioning groove is provided inside the adjustment ring.

[0014] As a further description of the above technical solution:

[0015] A limiting plate is slidably connected inside the housing, and a button is fixedly connected to one side of the limiting plate.

[0016] As a further description of the above technical solution:

[0017] A positioning block is fixedly connected to the outer wall of the button, and the positioning block is fitted into the positioning groove.

[0018] As a further description of the above technical solution:

[0019] A limiting block is fixedly connected inside the housing, and a sliding groove is provided on the circumferential side of the limiting plate. The limiting block is slidably connected in the sliding groove of the limiting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the bracket is first inserted into the connecting seat after passing through the connecting plate via the connecting pins on both sides. Rotating the bolt drives the conical column to extend into the connecting pin. The outer wall of the conical column adheres to the steel ball and pushes it out from the connecting pin, which achieves the effect of facilitating the assembly of the argon cylinder bracket. This solves the problem of needing to use tools when connecting the spectrometer to the argon cylinder bracket, and improves the convenience of the spectrometer.

[0024] 2. In this utility model, the display screen rotates around the adjustment ring as the center, and the button is limited in the housing by the limiting plate. After the button is released, the tension of the spring supports the button reset positioning block to re-embed in the positioning groove for locking. This achieves the effect of facilitating the adjustment of the display screen angle, solving the problem that the display screen angle of the spectrometer is not easy to adjust, which is inconvenient for different users, and improving the practicality of the spectrometer.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a mobile direct-reading spectrometer, comprising a body 1. The body 1 used in this application is a HITACHI-manufactured PMI-Master Pro / Pro2 mobile direct-reading spectrometer, equipped with a spark excitation gun, an arc excitation gun, a combined excitation gun, a UVPro excitation gun, or a UVTouch excitation gun, which are existing technologies and will not be described in detail here. A display screen 3 is provided on the top of the body 1. The display screen 3 is used to display the spectral detection results in real time, which is convenient for users to adjust parameters and read data. A port slot 2 is provided on one side of the body 1. The port slot 2 is used for external signal transmission and power supply connection, which improves the system's expandability and versatility. A bracket 4 is provided on the other side of the port slot 2. The bracket 4 is used to install an argon cylinder 5 to provide a stable inert gas environment for sample analysis reaction. A connecting component is provided between the bracket 4 and the body 1. The connecting component facilitates quick assembly and disassembly between the bracket 4 and the body 1, which improves the maintainability of the equipment and the convenience of on-site use.

[0034] The connecting assembly includes a connecting plate 7, one side of which is fixedly connected to the outer wall of the bracket 4, serving as support and positioning. An argon cylinder 5 is housed inside the bracket 4, providing a protective atmosphere for spectral analysis and preventing oxidation interference in the detection environment. A connecting seat 6 is fixedly connected to the other side of the body 1 for installation with the connecting plate 7. A connecting pin 9 passes through the inside of the connecting plate 7, allowing it to be mechanically locked into the connecting seat 6 during installation, enhancing connection reliability. A slot 8 is provided inside the connecting seat 6, which engages with the external components of the connecting pin 9 for limiting and fixing. A limit component is provided on the outer wall of the connecting pin 9 to prevent excessive displacement or dislodgement during insertion, ensuring connection stability. A bolt 11 is threaded inside the connecting pin 9, and the bolt 11 rotates... The bolt 11 is used to drive the internal components to switch the connection state. One end of the bolt 11 is fixedly connected to a conical column 12. When the bolt 11 is rotated, the conical column 12 is inserted into the connecting pin 9 to push the steel ball 13 to move. The outer wall of the conical column 12 is a conical structure, which is used to push the steel ball 13 out of the outer wall of the connecting pin 9, so that the steel ball 13 is engaged with the slot 8 to achieve a quick locking effect. The connecting pin 9 is provided with a steel ball 13. After being pushed by the conical column 12, the steel ball 13 moves outward and is embedded in the slot 8, thereby completing the fixed connection between the bracket 4 and the body 1. The limiting component includes a limiting ring 10. The limiting ring 10 is fixedly connected to the outer wall of the connecting pin 9 to limit the axial movement of the connecting pin 9 and prevent the connection from loosening. One side of the limiting ring 10 is in contact with the outer wall of the connecting plate 7 to further enhance the structural stability and assembly consistency of the connecting component.

[0035] Reference Figure 4 and Figure 5A housing 14 is fixedly connected to the top of the main body 1. The housing 14 provides installation space for the rotation and limiting structure of the display screen 3, ensuring the stability of the adjustment structure of the display screen 3. A limiting groove 15 is formed inside the housing 14, which provides a rotation trajectory and structural guide for the adjusting ring 17, realizing the controllable adjustment of the angle of the display screen 3. An adjusting ring 17 is fixedly connected to the bottom of the display screen 3. The adjusting ring 17 realizes its overall angle adjustment function by being fixedly connected to the display screen 3. One end of the adjusting ring 17 is rotatably connected inside the limiting groove 15, so that it can rotate stably around the axis formed by the limiting groove 15. The adjustment ring 17 has a positioning groove 18 inside, which is used to lock the angle of the display screen 3 with the positioning block 21 to prevent loosening or angle deviation after adjustment. A limit plate 20 is slidably connected inside the housing 14. The limit plate 20 can slide back and forth in the horizontal direction. It is used to drive the positioning block 21 out of the positioning groove 18 after the button 19 is pressed, realizing the unlocking function of the adjustment structure. A button 19 is fixedly connected to one side of the limit plate 20. The button 19 is used for user operation input. When the button 19 is pressed, it can drive the limit plate 20 to slide, completing the release of the structure. During the release process, a positioning block 21 is fixedly connected to the outer wall of button 19. The positioning block 21 can disengage from or engage with the positioning groove 18 during the sliding of the limiting plate 20, thereby locking or unlocking the adjusting ring 17. The positioning block 21 engages with the positioning groove 18, ensuring that the angle of the adjusting ring 17 remains unchanged when button 19 is not pressed, thus guaranteeing the angular stability of the display screen 3 during use. A limiting block 16 is fixedly connected inside the housing 14, which restricts the sliding range of the limiting plate 20 to prevent excessive displacement under external force and structural damage. A sliding groove is provided on the circumferential side of the limiting plate 20. The limiting block 16 is slidably connected in the groove of the limiting plate 20. The structural fitting ensures the guiding and stability of the limiting plate 20. A spring 22 is provided inside the housing 14. The spring 22 provides elastic restoring force for the reset structure and is used to restore the limiting plate 20 to its original position after the button 19 is released. One end of the spring 22 is fixedly connected inside the housing 14 to provide a fixed fulcrum. The other end of the spring 22 is fixedly connected to the other side of the limiting plate 20 to transmit elastic force, so that the limiting plate 20 and the button 19 can complete automatic reset, ensuring that the positioning block 21 is re-fitted into the positioning groove 18, and realizing reliable locking of the display screen angle 3.

[0036] Working principle: When using this mobile direct-reading spectrometer, firstly, when the bracket 4 is combined with the body 1, the bracket 4 passes through the connecting plate 7 and is inserted into the connecting seat 6 through the connecting pins 9 on both sides. The connecting plate 7 is attached to one end of the connecting seat 6 on one side of the body 1. Then, the connecting pin 9 is limited on one side of the connecting plate 7 by the limiting ring 10. Then, the bolt 11 is rotated to drive the conical column 12 to extend into the connecting pin 9. Then, the outer wall of the conical column 12 is attached to the steel ball 13, pushing the steel ball 13 out of the connecting pin 9, so that the steel ball 13 is embedded in the slot 8 to fix the bracket 4 and the body 1, which achieves the effect of facilitating the assembly of the argon cylinder 5 bracket 4.

[0037] When the angle of the display screen 3 needs to be adjusted, press button 19 to retract it into the housing 14. Then, the positioning block 21 on the outer wall of button 19 separates from the positioning groove 18 in the adjusting ring 17. Then, the display screen 3 rotates around the adjusting ring 17. Button 19 is limited in the housing 14 by the limiting plate 20. After it is in place, release button 19 and the tension of spring 22 will support button 19, causing the positioning block 21 to re-embed into the positioning groove 18 for locking. Button 19 is prevented from rotating with the adjusting ring 17 by the limiting block 16, thus achieving the effect of facilitating the adjustment of the angle of the display screen 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
