[0002] TVOC detector is an instrument used to measure the concentration of harmful gases such as total volatile organic compounds in indoor air. TVOC includes a variety of chemical substances, such as benzene, toluene, ethylbenzene, xylene, etc. These substances may have adverse effects on human health. TVOC detectors are usually used in indoor air quality monitoring, environmental assessment, industrial safety testing and other fields to ensure the safety and health of the indoor environment.

[0003] Although the existing TVOC detector can detect the required substances during use, it is not convenient to carry the TVOC detector, which requires staff to spend a lot of time to open the TVOC detector when using it. At the same time, the display screen cannot be protected, resulting in damage to the TVOC detector's display screen due to external factors during detection, thereby reducing the service life of the TVOC detector. For this reason, a portable TVOC detector is introduced. Utility Model Content

[0024] In the above structure, during operation, the staff places the limit rod 13 into the movable groove 9 on the inner wall of the placement shell 7 and slides it to the bottom, thereby applying pressure to the pressure plate 12. Under the influence of this pressure, the pressure plate 12 pushes the fixed block 15 and the steel rope 16 to move, and then the steel rope 16 applies tension to the rotating plate 20 during the movement. When the rotating plate 20 is subjected to the tension, it drives the rotating rod 19 to rotate in the inner wall of the placement block 18. During the rotation process, the rotating plate 20 engages with the clamping block 21 to engage with the inner wall of the clamping groove 17. The limit is set, thereby realizing the positioning of the limit rod 13 and the fixing belt 14, so that the staff can carry it conveniently. When using the detector body 1, the staff pulls the rotating plate 20 to drive the steel rope 16 and the fixed block 15 to apply pressure to the pressure plate 12. When the rotating plate 20 cancels the restriction on the spring 11 during the opening process, the elastic potential energy of the spring 11 is released. With the help of the rebound force of the spring 11 and the pulling force of the staff, the limit rod 13 can be quickly moved out from the inner wall of the movable groove 9, thereby realizing the rapid loading and unloading of components.

[0026] In the above structure, the display screen 5 provides the user with the monitored values, the fixing plate 2 and the rotating column 3 are used to limit the protective shell 4, and the protective shell 4 protects the display screen 5.

[0028] In the above structure, the operator applies pressure to the clamping block 605, so that after being compressed, the rotating shaft 603 is driven to rotate along the inner wall of the support rod 602, thereby opening the clamping block 605. Subsequently, the operator rotates the protective shell 4, so that it drives the connecting part between the placement plate 601 and the clamping block 605 to stop rotating. At the same time, the operator releases the pressure on the clamping block 605, so that the elastic potential energy of the spring 2 604 is released, thereby pushing the clamping block 605 and the limit block 606 to rotate. Finally, the limit block 606 is placed on the inner wall of the limit groove 8, thereby realizing the limit fixation of the protective shell 4, ensuring that it provides protection for the display screen 5.

[0029] In a preferred embodiment, the steel rope 16 is fixedly assembled with the rotating plate 20 , the placement plate 601 is fixedly assembled with the outer wall of the detector body 1 , and the second spring 604 is fixedly assembled with the clamping block 605 .

[0030] In the above structure, the steel rope 16 drives the rotating plate 20 and the rotating rod 19 to rotate on the inner wall of the placement block 18 when moving, and the clamping assembly 6 is limited by the detector body 1, and the clamping block 605 is supported by the elastic potential energy of the spring 2 604.

[0031] In a preferred embodiment, the engaging block 21 engages with the inner wall of the engaging groove 17 , the limiting block 606 matches the inner wall of the limiting groove 8 , and the fixing belt 14 is made of rubber.

[0032] In the above structure, the clamping block 21 is clamped with the inner wall of the clamping groove 17 to limit the limit rod 13, so that the limit rod 13 is limited on the inner wall of the movable groove 9. The limit block 606 is adapted to the inner wall of the limit groove 8, so that the limit block 606 is placed on the inner wall of the limit groove 8 to fix the protective shell 4. The fixing belt 14 is made of rubber, so that the fixing belt 14 will automatically stretch when it is subjected to tension.

[0033] In a preferred embodiment: the number of the placement shell 7, the limiting rod 13, the snap-in groove 17, the rotating plate 20, and the snap-in block 21 are two, and the two placement shells 7, the limiting rod 13, the snap-in groove 17, the rotating plate 20, and the snap-in block 21 are respectively located on the outer walls on both sides of the detector body 1.

[0034] In the above structure, the two ends of the fixing belt 14 are fixed by the two placement shells 7, the limiting rod 13, the clamping groove 17, the rotating plate 20, and the clamping block 21 to prevent one end of the fixing belt 14 from falling off when carrying.

[0035] Working principle: By placing the limiting rod 13 into the movable groove 9 of the inner wall of the device of the placement shell 7, when the limiting rod 13 slides to the bottom, pressure is applied to the pressure plate 12. After the pressure plate 12 is compressed, the fixed block 15 and the steel rope 16 are driven to move, and then the steel rope 16 applies tension to the rotating plate 20 during the movement. After the rotating plate 20 is subjected to tension, it drives the rotating rod 19 to rotate in the inner wall of the placement block 18. At the same time, the rotating plate 20 prompts the clamping block 21 to clamp with the inner wall of the clamping groove 17 during rotation. The limiting rod 13 and the fixing belt 14 are limited by the clamping block 21 and the clamping groove 17, so that it is convenient for the staff to carry. When using the detector body 1, the staff pulls the rotating plate 20, so that the rotating plate 20 drives the steel rope 16 and the fixed block 15 to apply pressure to the pressure plate 12. When the rotating plate 20 opens When the pressure on the clamping block 605 is released, the elastic potential energy of the spring 11 is released. With the help of the rebound force of the spring 11 and the pulling force of the staff, the limit rod 13 can be quickly moved out from the inner wall of the movable groove 9, realizing the rapid loading and unloading of parts. The staff presses the clamping block 605 to press it and drive the rotating shaft 603 to rotate in the inner wall of the support rod 602, causing the clamping block 605 to open. Then the staff rotates the protective shell 4 so that it drives the placement plate 601 to connect with the clamping block 605 and then stops rotating. When the staff releases the pressure on the clamping block 605, the elastic potential energy of the spring 2 604 is released, thereby driving the clamping block 605 and the limit block 606 to rotate, placing the limit block 606 in the inner wall of the limit groove 8, realizing the limit fixation of the protective shell 4, and ensuring that the protective shell 4 provides protection for the display screen 5.
