[0025] Includes: an air sampler body 01, a protective component 02 on the upper outer wall of the air sampler body 01, and an installation component 03 on the lower part of the air sampler body 01;

[0026] The protective component 02 includes a screw sleeve 21, with a nut 22 connected to the outer wall of the screw sleeve 21. A protective cover 23 is fixedly installed above the nut 22, and a protective cap 24 is provided above the protective cover 23. The protective cap 24 serves a protective function to prevent dust from accumulating at the intake of the air sampler body 01 during storage. The protective cap 24 is connected to the protective cover 23 via a hinge 25. A locking block 26 is fixedly provided below the end of the protective cap 24 away from the hinge 25, which can be locked into the slot of the protective cover 23 to limit the position of the protective cap 24.

[0027] Furthermore, the mounting assembly 03 includes a base plate 31, with a fixing rod 32 fixedly mounted in the middle of the lower surface of the base plate 31. A first gear 33 is connected to the outer wall of the fixing rod 32, and a second gear 34 meshes with the outer wall of the first gear 33. A rotating rod 35 passes through the interior of the second gear 34. Rotating the rotating rod 35 can drive the third gear 37 to rotate. An insert rod 36 is provided on the outer wall of the rotating rod 35. The third gear 37 is fixedly connected to the outer wall of the end of the rotating rod 35 away from the second gear 34. Tooth plates 38 mesh with the outer walls of both ends of the third gear 37. A limit plate 39 is fixedly mounted on one end of the tooth plate 38. The limit plate 39 moves out of the insert rod 36 to limit the insertion rod 36.

[0028] Furthermore, the screw sleeve 21 is fixedly connected to the air sampler body 01 to ensure the firmness of the screw sleeve 21 position. The nut 22 is threadedly connected to the screw sleeve 21. The protective cover 23 has a slot corresponding to the size of the locking block 26, which can be inserted into the slot of the protective cover 23 to limit the position of the protective cover 24.

[0029] Furthermore, the protective cover 24 is rotatably connected to the protective cover 23 via the hinge 25. The protective cover 24 serves a protective function, preventing dust from accumulating at the air sampler body 01 intake during storage. The base plate 31 is fixedly connected to the air sampler body 01, ensuring the stability of the base plate 31.

[0030] Furthermore, gear 33 is rotatably connected to fixed rod 32, and gear 34 and rotating rod 35 are rotatably connected to base plate 31, ensuring that base plate 31 does not affect the rotation of gear 34 and rotating rod 35.

[0031] Furthermore, the second gear 34 is fixedly connected to the rotating rod 35, ensuring that the second gear 34 can drive the rotating rod 35 to rotate when it rotates.

[0032] Furthermore, the rotating rod 35 is rotatably connected to the insert rod 36 to ensure that the insert rod 36 does not affect the rotation of the rotating rod 35. The rotation of the rotating rod 35 can drive the third gear 37 to rotate. The gear plate 38 and the limiting plate 39 are both slidably connected to the insert rod 36. The limiting plate 39 moves out of the insert rod 36 to limit the insertion rod 36.

[0033] Working principle: In use, first insert the rod 36 through the bolt hole of the bracket, then rotate the first gear 33. The first gear 33 drives the second gear 34 to rotate, which in turn drives the rotating rod 35 to rotate. The rotating rod 35 then drives the third gear 37 to rotate, which in turn moves the toothed plate 38 and the limiting plate 39, causing the limiting plate 39 to move out of the rod 36. Before storing the air sampler body 01, the nut 22 can be turned upwards. The nut 22 moves the protective cover 23. When the top of the protective cover 23 is higher than the air sampler body 01, the protective cover 24 is rotated to the upper surface of the protective cover 23 via the hinge 25, causing the locking block 26 to engage in the slot of the protective cover 23, thus limiting the position of the protective cover 24. The above is the complete working principle of this utility model.
