The support cylinder 1102 is fixedly connected to the outer side wall of the fixing ring plate 1103. The bottom of the support cylinder 1102 is fixedly connected to the mounting ring plate 12. The fixing cylinder 1101 and the support cylinder 1102 can expand the support area at the bottom of the dust monitor. The friction between the friction pad 1104 and the fixing cylinder 1101 is relatively large, which can better offset the elastic potential energy generated by the spring 1105.

[0032] The friction pad 1104 is made of rubber material. Rubber has good elasticity and a large friction coefficient.

[0033] The first support structure 8 includes a support circular shell 801 and a support frame 802. The top and bottom of the support circular shell 801 are fixedly connected to the support frame 802. The support frame 802 at the bottom of the support circular shell 801 is fixedly connected to the top of the support rod 2. The support frame 802 at the top of the support circular shell 801 is fixedly connected to the bottom of the fixing frame 4.

[0034] Equal-distance ventilation grooves 9 are provided on the side walls of the support frame 802. The ventilation grooves 9 can facilitate the passage of strong winds and can appropriately reduce some wind resistance.

[0035] An annular limiting block 17 is fixedly connected to the inner side wall of the supporting circular shell 801 , and the limiting block 17 can prevent the rotating block 1601 from separating from the supporting circular shell 801 .

The inner wall of the protective shell 1001 is fixedly connected to the display screen 15. The front side wall of the protective shell 1001 is fixedly connected to the observation plate 1002. The observation plate 1002 will not block people's line of sight and can also protect the display screen 15.

[0038] The observation plate 1002 is made of a transparent plastic plate.

[0039] When the utility model is in use, the electrical components appearing in the present application are all externally connected to a power source and a control switch. When installing the dust monitor, the fixing bolts are passed through the mounting holes 13 to fix the entire dust monitor on the ground. When blown by strong winds, the protective shell 1001 rotates under the strong winds, and the protective shell 1001 drives the display screen 15 and the rotating block 1601 to rotate, the torsion springs 16031105 rotate, and the display screen 15 tilts, which can effectively reduce wind resistance. The support frame 802 is opened The ventilation slots 9 are designed to facilitate the passage of strong winds and appropriately reduce some wind resistance, so that when the dust monitor is blown by strong winds, the wind resistance on the upper part can be reduced. When it is not blown by strong winds, the torsion spring 16031105 drives the display screen 15 back to its original position. The PM2.5 sensor 3, temperature and humidity sensor 5, wind speed sensor 6 and wind direction sensor 7 above can monitor PM2.5, temperature and humidity, wind speed and wind direction in the air, and then display them on the display screen 15. The observation board 1002 is made of a transparent plastic board. The dust monitor 1101 and the support tube 1102 can expand the support area at the bottom of the dust monitor, so that the dust monitor can be supported stably. When the dust monitor shakes under strong wind, the friction pad 1104 will produce a certain degree of extrusion deformation, and the fixing ring plate 1103 and the spring 1105 at the bottom of the friction pad 1104 will also produce a certain degree of compression or Stretching, when the spring 1105 is compressed or stretched, a certain elastic force will be generated, and the friction pad 1104 is made of rubber, which also has a certain elastic force. The elastic force of the spring 1105 and the elastic force of the friction pad 1104 can reduce the impact of the shaking on the fixation of the bottom and the ground, thereby better ensuring that the dust monitor is more stably supported on the ground. At the same time, the friction between the friction pad 1104 and the fixed tube 1101 is relatively large, which can better offset the elastic potential energy generated by the spring 1105 and avoid the continuous bouncing of the spring 1105.

[0040] The benefits of this application are:

[0041] 1. The structure of the present application is reasonable. The protective shell will rotate under the influence of strong wind. The protective shell drives the display screen and the rotating block to rotate. The torsion spring rotates, and the display screen tilts, which can effectively reduce wind resistance. The ventilation slots on the support frame can facilitate the passage of strong wind and appropriately reduce some wind resistance. When the dust monitor is blown by strong wind, the wind resistance on the upper part can be effectively reduced.

[0042] 2. The present application has a reasonable structure. The observation panel is made of a transparent plastic panel, which will not block people's sight. At the same time, it can also protect the display screen, thereby better protecting the display screen and preventing debris caused by strong wind from hitting the display screen and causing damage to the display screen.

[0043] 3. The structure of the present application is reasonable. The fixing tube and the supporting tube can expand the supporting area of ​​the bottom of the dust monitor. When the dust monitor shakes to a certain extent under strong wind, the friction pad will produce a certain extrusion deformation, and the spring at the bottom of the fixed ring plate and the friction pad will also produce a certain compression or stretching. When the spring is compressed or stretched, it will produce a certain elastic force, and the friction pad also has a certain elastic force. Through the elastic force of the spring and the elastic force of the friction pad, the impact of the shaking on the fixation of the bottom of the dust monitor to the ground can be reduced, which is convenient for better ensuring that the dust monitor is more stably supported on the ground.
