[0027] like Figures 1-8 As shown, this embodiment provides a handheld near-infrared spectroscopy analyzer, including an analyzer housing 1 and a display screen 2.

[0028] The top of the analyzer housing 1 is provided with a mounting assembly 3 for mounting the display screen 2. Inside the analyzer housing 1 are a spectral module circuit board 18, a spectral analyzer 19, a detection probe 20, and control buttons 21. The spectral module circuit board 18 is located inside the analyzer housing 1, and the detection probe 20 is located on one side of the front of the spectral module circuit board 18 via the spectral analyzer 19. The control buttons 21 are connected to the spectral module circuit board 18. The bottom of the analyzer housing 1 is provided with a grip handle 23, and the grip handle 23 contains a power supply battery 24 for powering the spectral module circuit board 18.

[0029] Specifically, after the detection probe 20 is installed, it is pressed onto the lens hole 22. The tobacco can be detected non-destructively through the spectrometer 19 and the detection probe 20. The control button 21 can control the start and stop of the spectrometer 19 and the detection probe 20, which is simple and convenient. The grip handle 23 at the bottom of the spectrometer housing 1 makes it easy for people to hold the spectrometer. The power supply battery 24 is placed in the grip handle 23, which can facilitate the power supply to the spectrometer module circuit board 18.

[0030] like Figure 2As shown, the analyzer housing 1 is also equipped with a power control switch 25. One end of the power control switch 25 is connected to the power supply battery 24, and the other end is connected to the spectrum module circuit board 18. The power control switch 25 can be used to control the power supply status of the power supply battery 24, which is simple and convenient.

[0031] like Figure 3 and Figure 4 As shown, the mounting assembly 3 includes a mounting plate 7 and a top limiting block 8, a side limiting block 9, and a bottom limiting block 10 fixed on the mounting plate 7. The mounting plate 7 is provided with a blocking limiting plate 4 and a baffle 15. The blocking limiting plate 4 includes a top blocking limiting plate 13 provided on the top edge of the mounting plate and a side blocking limiting plate 14 provided on the side. The baffle 15 is provided on the bottom edge of the mounting plate 7. The top edge and side edge of the back of the display screen are provided with locking strips 5, and a limiting recess 6 is provided below the locking strips 5.

[0032] Specifically, when the display screen 2 is mounted on the mounting component 3, the limiting recess 6 on the display screen 2 is mounted on the mounting component 3, and the locking strip 5 on the outer edge of the display screen 2 is fitted into the gap between the blocking limiting plate 4 and the mounting component 3. Because the mounting component 3 is provided inside the analyzer housing 1, when the display screen 2 needs to be fixed, the limiting recess 6 on the back of the display screen 2 is mounted on the mounting component 3, while the locking strip 5 on the back of the display screen 2 is mounted in the gap 26 between the blocking limiting plate 4 and the mounting component 3, which facilitates double fixing of the display screen 2.

[0033] The locking strip 5 on the back of the display screen 2 is locked in the gap between the blocking limit plate 4 and the top limiting block 8, or between the blocking limit plate 4 and the side limiting block 9. The mounting plate 7, the top limiting block 8, the side limiting block 9 and the bottom limiting block 10 can fasten the limiting recess 6 on the back of the display screen 2.

[0034] The top limiting plate 13, the side limiting plate 14, and the bottom baffle 15 can limit and lock the locking strip 5 on the back of the display screen 2 from all sides. The mounting plate 7 has screw fixing posts 16 with internal threads at the corners. The screw fixing posts 16 facilitate the connection and fixation of the mounting plate 7 and the spectrum module circuit board. In addition, the outside of the screw fixing posts 16 is provided with reinforcing ribs 17 that are connected to the mounting plate 7. One end of the reinforcing rib 17 is connected to the screw fixing post 16, and the other end is connected to the mounting plate 7. The reinforcing rib 17 strengthens the connection of the screw fixing post 16.

[0035] like Figure 6 and Figure 7As shown, the mounting assembly 3 also includes an inner groove 11 and a heat conduction groove 12. The inner groove 11 is horizontally arranged on the mounting plate 7, located between the side end limiting block 9 and the bottom limiting block 10 of the display screen. One end of the heat conduction groove 12 is connected to the inner groove 11, and the other end extends to the edge of the mounting plate 7.

[0036] The locking strips 5 on the top edge and side of the back of the display screen 2 are respectively connected to the top limiting block 8 and the side limiting block 9 on the mounting plate 7.

[0037] Specifically, the inner groove 11 and the heat conduction groove 12 can be used for heat dissipation of the display screen 2. With this setting, the display screen 2 can be better fixed to the analyzer housing 1. Compared with the existing technology, it can provide better fixation for the display screen 2.

[0038] The working principle of this utility model:

[0039] When the display screen is mounted on the mounting assembly, the limiting recesses on the display screen engage with the top limiting block, side limiting block, and bottom limiting block. The locking strip on the outer edge of the display screen fits into the gap between the blocking limiting plate and the top limiting block, or between the limiting plate and the side limiting block, providing a double limiting function. However, no locking strip is inserted on the outside of the bottom limiting block. Therefore, during disassembly, the display screen can be pried open from the bottom of the mounting assembly. However, during installation, the display screen is securely mounted due to the locking mechanism of the analyzer housing. In addition, the blocking limiting plate further strengthens the fixation of the display screen. Furthermore, the recessed grooves and heat-conducting grooves on the mounting plate create a gap on the back of the display screen, facilitating heat dissipation and ensuring that the use of the display screen is not affected, further strengthening the fixation of the display screen.

[0040] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
