[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses a waterproof and shockproof housing assembly for a VOC water quality analyzer, comprising: an analyzer 1, with a housing 2 on the outer surface of the analyzer 1, providing physical protection for the analyzer 1 to prevent it from being affected by water and vibration, ensuring its normal operation in complex environments; sliding grooves 6 are provided at the four corners of the inner surface of the housing 2, providing a path for the sliding of abutment plates 8, allowing them to move within a specific range to buffer and fix the analyzer 1; limiting grooves 7 are provided on the outer surface of the sliding grooves 6, which cooperate with limiting posts 11 to limit the sliding range of the abutment plates 8, preventing them from sliding excessively and losing their protective function for the analyzer 1; and the abutment plates 8 are slidably connected inside the sliding grooves 6, and the abutment plates 8... The sliding within the sliding groove 6 provides a buffer when the analyzer 1 is subjected to vibration, reducing the impact of vibration on the analyzer 1. The lower surface of the contact plate 8 is fixedly connected to the guide post 9 and the connecting post 10, which provide guidance for the sliding of the contact plate 8, ensuring its stability and preventing deviation. The outer surface of the guide post 9 is fitted with a spring 12, and the lower surface of the spring 12 abuts against the sliding groove 6. When the analyzer 1 is subjected to vibration, the spring 12 is compressed to absorb the vibration energy and then returns to its original shape, playing a role in buffering and shock absorption. The outer surface of the connecting post 10 is fixedly connected to the limiting post 11, and the limiting post 11 is slidably connected to the inside of the limiting groove 7. The limiting post 11 slides within the limiting groove 7, further ensuring the stability and accuracy of the sliding of the contact plate 8.

[0024] The interior of the sliding groove 6 is connected to the interior of the outer shell 2. This connection allows the contact plate 8 to slide in a specific area inside the outer shell 2, thus effectively buffering the analyzer 1. The interior of the limiting groove 7 is connected to the interior of the sliding groove 6, ensuring that the limiting post 11 can slide smoothly within the limiting groove 7, cooperating with the sliding of the contact plate 8 within the sliding groove 6. The connecting post 10 is located on the outer surface of the guide post 9, and the size of the connecting post 10 is adapted to the size of the contact plate 8. This layout and adaptation relationship allows the guide post 9 and the connecting post 10 to work together better, providing stable guidance for the contact plate 8. The upper and lower surfaces of the limiting post 11 abut against the inner surface of the limiting groove 7. This abutment relationship ensures the stability of the limiting post 11 when sliding within the limiting groove 7, preventing it from shaking and affecting the overall buffering effect. The contact plate 8 is located below the analyzer 1, providing support for the analyzer 1 from below. To buffer and reduce the impact of vibrations from the bottom on the analyzer 1, the inner surface of the outer casing 2 is fixedly connected to the four corners of the casing, and the sidewalls of the interlocking blocks 13 abut against the analyzer 1. The interlocking blocks 13 fix the analyzer 1 in a specific position inside the casing 2 to prevent it from shaking inside the casing 2. The upper surface of the analyzer 1 abuts against the sealing strip 3. The sealing strip 3 can prevent water from entering from the connection between the analyzer 1 and the casing 2, and plays a role in waterproof sealing. The upper surface of the sealing strip 3 is threaded with the four corners of the sealing strip 3, and the positioning bolts 4 extend into the interior of the casing 2. The positioning bolts 4 fix the sealing strip 3 to the casing 2, enhance the sealing effect, and ensure waterproof performance. The front surface of the casing 2 is fixedly connected to the left and right sides of the sealing joints 5. The sealing joints 5 are compatible with the analyzer 1 and provide a sealed connection for the circuits of the analyzer 1, preventing water from entering the interior of the analyzer 1 through the circuit interface.

[0025] Working principle: First, place the analyzer 1 inside the housing 2, so that the side wall of the analyzer 1 abuts against the four corner fittings 13 on the inner surface of the housing 2. The fittings 13 will fix the analyzer 1 in a specific position inside the housing 2, preventing it from shaking. At the same time, the lower surface of the analyzer 1 will contact the abutment plate 8. Place the sealing strip 3 on the upper surface of the analyzer 1, so that the two abut against each other. Then, use a tool to connect the positioning bolts 4 from the four corner threads on the upper surface of the sealing strip 3 and extend them into the inside of the housing 2, thereby fixing the sealing strip 3 to the housing 2, enhancing the sealing effect and preventing water from entering from the connection between the analyzer 1 and the housing 2. Connect the sealing joints 5 on the left and right sides of the front surface of the housing 2 to the analyzer. The instrument 1 is adapted and connected to provide a sealed connection for the circuitry of the analyzer 1, preventing water from entering the analyzer 1 through the circuit interface. After completing the above installation steps, the VOC water quality analyzer can be used normally for water quality testing. When the analyzer is vibrated, the contact plate 8 will slide in the sliding groove 6. The guide post 9 and the connecting post 10 provide guidance for its sliding, ensuring the stability of the sliding process. At the same time, the limiting post 11 on the outer surface of the connecting post 10 will slide in the limiting groove 7, limiting the sliding range of the contact plate 8 and preventing it from sliding excessively. In addition, the spring 12 sleeved on the outer surface of the guide post 9 will be compressed to absorb the vibration energy, playing a role in buffering and shock absorption, and protecting the analyzer from damage.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
