[0002] A laser gas analyzer is an instrument that uses laser spectroscopy to detect and analyze the composition of gases. It determines the presence and concentration of a gas by measuring its absorption of laser light. Laser gas analyzers can be used in a variety of applications, including industrial process control, environmental monitoring, healthcare, and scientific research.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the existing laser gas analyzers have poor protective performance. If they are subjected to external impact or are accidentally dropped, they are easily damaged, reducing their service life.

[0004] The prior art (202420997584.3) discloses a laser gas analyzer that is protected by a protective box. However, the analyzer still needs to be moved out of the protective box during testing, so it may still be subject to external impacts. Although rubber pads are provided, the protective box does not provide adequate cushioning when dropped during transportation and cannot completely protect the laser gas analyzer.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] Appendix Figure 1-3The protective box for the online laser gas analyzer of this utility model includes a protective box 1, sealing doors 2 disposed on the top and sides of the protective box 1, a translation plate assembly 3 disposed inside the protective box 1 and moving towards the sealing doors 2 on the side of the protective box 1, a baffle 44 assembly 4 telescopically disposed on the translation plate assembly 3 with an opening at one end facing the sealing doors 2 on the side of the protective box 1 and having a shock-absorbing effect, a laser gas analyzer body 5 placed in the middle of the baffle 44, a shock-absorbing assembly 6 disposed on the baffle 44 assembly 4 for limiting the laser gas analyzer body 5 and for multi-directional shock absorption of the laser gas analyzer body 5; the baffle 44 assembly 4 includes a bottom plate 41 disposed inside the protective box 1, and two ends respectively connected to the four corners of the bottom plate 41 and the translation plate assembly 3. The system includes four first telescopic rods 42 connected to the ends, four first springs 43 sleeved on the four first telescopic rods 42 for shock absorption, and three baffles 44 located on the top surface of the base plate 41 away from the sealing door 2 and on both sides of the sealing door 2. The main body 5 of the laser gas analyzer is placed on the base plate 41. The shock absorption assembly 6 includes three sliding holes 6a in the middle of the three baffles 44, multiple limiting grooves 6b on the inner walls of the upper and lower sides of the three sliders, multiple sliding plates 6c that slide in the three sliders and are inserted into the multiple limiting grooves 6b at their lower ends, multiple drive rods 6d that are telescopically mounted on the multiple sliding plates 6c and extend to the top of the base plate 41, and multiple drive rods 6d connected to the multiple drive rods 6d and located on the side of the protective box 1. The protective box 1 has the following components: two C-shaped buffer plates 6e on both sides of the sealed door 2 to enclose the main body 5 of the laser gas analyzer; multiple second springs 6f respectively fitted onto the multiple drive rods 6d at both ends of the multiple sliding plates 6c; multiple second telescopic rods 6g set on the sealed door 2 at the top of the protective box 1 to limit the top surface of the main body 5 of the laser gas analyzer; multiple rubber heads 6h set on the telescopic ends of the multiple second telescopic rods 6g; multiple third springs 6i fitted onto the multiple second telescopic rods 6g and connected at both ends to the multiple rubber heads 6h and the sealed door 2; multiple limiting plates 6j respectively set on the ends of the multiple drive rods 6d away from the bottom plate 41 to prevent the springs on the corresponding ends from falling off; and three retaining plates set on the side wall of the protective box 1 for the telescopic movement of the multiple drive rods 6d. The groove 6k; the two buffer plates 6e face the side sealing door 2 of the protective box 1 with an opening on one side to facilitate detection by the main body 5 of the laser gas analyzer; the translation plate assembly 3 includes two drive plates 31 slidably disposed inside the bottom of the protective box 1 on both sides of the side sealing door 2 of the protective box 1, two mounting plates 32 disposed inside the bottom of the protective box 1 between the two ends of the two drive plates 31, a threaded rod 33 rotatably disposed between the two mounting plates 32 and rotatably connected at both ends to the middle of the two mounting plates 32, a drive block 34 threadedly connected to the threaded rod 33 and connected at both ends to the end of the two drive plates 31 away from the side sealing door 2 of the protective box 1, and a drive motor 35 disposed in the inner wall of the protective box 1 for driving the threaded rod 33 to rotate.

[0016] Furthermore, heat dissipation holes 7 are provided on the three limiting plates 6j and in the three clearance slots 6k to prevent overheating from damaging the equipment.

[0017] In use: First, open the sealing door 2 on the top of the protective box 1, then pry open the limiting plate 6j, and then place the laser gas analyzer body 5 between the three limiting plates 6j. Then, the three limiting plates 6j are pushed to fit against the side of the laser gas analyzer body 5 by the second spring 6f. Since the limiting plates 6j on both sides of the laser gas analyzer body 5 are L-shaped, the bent end is used to limit the front of the laser gas analyzer body 5 to prevent the laser gas analyzer body 5 from sliding out. Then, close the top of the protective box 1, and then the rubber head 6h on the telescopic end of the second telescopic rod 6g presses against the laser gas... The top surface of the analyzer body 5 is limited, and the third spring 6i provides shock absorption for the laser gas analyzer body 5. When analysis is required, the sealing door 2 on the side of the protective box 1 is opened and the drive motor 35 is started. The drive motor 35 drives the threaded rod 33 to rotate, which in turn drives the drive block 34 to move. The drive block 34 then drives the two drive plates 31 to move out of the protective box 1. The drive plates 31 then drive the first telescopic rod 42 to move, which in turn drives the base plate 41 and the baffle 44 to move. The base plate 41... The laser gas analyzer body 5 is moved. After the laser gas analyzer body 5 moves out of the protective box 1, the data cable for detection is plugged into the laser gas analyzer body 5. Then, the drive motor 35 reverses and resets the laser gas analyzer body 5. Thus, the protective box 1 can still be used to protect the laser gas analyzer body 5 from external impacts during analysis. When the protective box 1 is accidentally dropped during transport, the laser gas analyzer body 5 inside the protective box 1 is impacted and shakes in multiple directions. The laser gas analyzer body 5 pushes the plate, base plate 41, and rubber... As the rubber head 6h moves, the second spring 6f on the drive rod 6d, the first spring 43 on the first telescopic rod 42, and the third spring 6i on the second telescopic rod 6g buffer the impact force, thereby preventing damage to the main body 5 of the laser gas analyzer. When the main body 5 of the laser gas analyzer moves in the forward, backward, left, and right directions, since the slide plate 6c can slide in the sliding hole 6a, it will not affect the movement of the buffer plate 6e connected to the drive rod 6d. Therefore, the buffer plate 6e will move with the main body 5 of the laser gas analyzer and, together with the second spring 6f, buffer the main body 5 of the laser gas analyzer.

[0018] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
