[0020] The universal wheel 3 drives the column 4 to move to the position that needs to be detected. During this process, the shock-absorbing component provides shock-absorbing protection for the base 1, so that the base 1 is more stable during movement. When the height of the air monitoring device body 7 needs to be adjusted according to different positions, the driving component and the rack 5 are used to adjust the height of the supporting plate 2, and the height of the air monitoring device body 7 is indirectly adjusted, which is suitable for monitoring the air by the air monitoring device body 7 at any position height. The supporting plate 2 is limited by the limiting component to prevent the supporting plate 2 from moving in series, thereby improving the stability of the supporting plate 2.

[0021] The present embodiment is further configured as follows: the shock absorbing assembly includes four shock absorbing boxes 9, the upper wall of the shock absorbing box 9 is provided with a through hole, a support rod 10 is inserted in the through hole, the upper end of the support rod 10 is fixedly connected to the lower wall of the base 1, a first spring 11 is fixedly installed between the base 1 and the outer upper wall of the shock absorbing box 9, the first spring 11 is sleeved on the support rod 10, the lower end of the support rod 10 is located in the shock absorbing box 9 and a baffle 12 is fixedly installed, a plurality of oil holes 13 are provided on the baffle 12, the shock absorbing box 9 is filled with damping oil 14, a second spring 15 is fixedly installed between the baffle 12 and the inner lower wall of the shock absorbing box 9, and the universal wheel 3 is installed on the outer lower wall of the shock absorbing box 9;

[0022] When the base 1 vibrates, the base 1 pushes the support rod 10 downward, thereby causing the first spring 11 to be compressed.

When the support rod 10 moves downward, the support rod 10 pushes the baffle 12 downward, and the baffle 12 squeezes the second spring 15. The second spring 15 is compressed and deformed, thereby playing a standing role. When the baffle 12 moves downward, the damping oil 14 moves from one side of the baffle 12 to the other side through the oil hole 13. Since the damping oil 14 is relatively viscous, the baffle 12 moves slowly in the damping oil 14 when moving. The damping oil 14 not only absorbs pressure and buffers shock, but also prevents the second spring 15 from rebounding back and forth, thereby playing a damping role.

[0023] The present embodiment is further configured as follows: the driving assembly includes a concave plate 16, the concave plate 16 is fixedly mounted on the lower wall of the connecting plate 6, a carrying box 17 is fixedly mounted on the outer rear wall of the concave plate 16, a shaft rod 18 is rotatably mounted between the front and rear walls of the concave plate 16, one end of the shaft rod 18 passes through the concave plate 16 and the carrying box 17, one end of the shaft rod 18 is rotatably mounted on the inner rear wall of the carrying box 17, a gear 19 is fixedly mounted on the shaft rod 18, the gear 19 is located in the concave plate 16, the gear 19 is meshed with the rack 5, a worm wheel 20 is fixedly mounted on the shaft rod 18, the worm wheel 20 is located in the carrying box 17, a worm 21 is rotatably mounted between the two side walls of the carrying box 17 and above the worm wheel 20, and the worm 21 is meshed with the worm wheel 20;

[0024] The worm 21 is rotated. Since the worm 21 is meshed with the worm wheel 20, the worm wheel 20 is driven to rotate when the worm 21 rotates. The worm wheel 20 drives the shaft 18 to rotate. The shaft 18 drives the gear 19 to rotate. Since the gear 19 is meshed with the rack 5, the gear 19 drives the carrier plate 2.

[0025] This embodiment is further configured such that one end of the worm 21 passes through the side wall of the carrying box 17 and is fixedly mounted with a crank;

[0026] The crank handle facilitates the worm 21 to be stressed.

[0028] The screw rod 23 is rotated and fed along the path of the threaded hole, and then the screw rod 23 pushes the pressure plate 24, and the pressure plate 24 contacts the column 4, thereby limiting the bearing plate 2 by increasing the pressure.

[0029] The present embodiment is further configured such that the front and rear walls of the column 4 are respectively provided with dovetail grooves 27, and the front and rear walls of the through hole are respectively fixedly installed with dovetail blocks 28, and the dovetail blocks 28 are slidably installed in the dovetail grooves 27;

[0030] When the carrying plate 2 moves, it moves along the path of the dovetail groove 27 under the action of the dovetail block 28 .

[0031] This embodiment is further configured such that a blocking plate 29 is fixedly mounted on the upper end of the column 4;

[0032] The blocking plate 29 prevents the carrying plate 2 from moving out from the upper end of the column 4 .

[0034] Embodiment: According to the drawings in the specification, the universal wheel 3 drives the column 4 to move to the position to be detected. When the base 1 vibrates, the base 1 pushes the support rod 10 downward, thereby causing the first spring 11 to be compressed.

When the support rod 10 moves downward, the support rod 10 pushes the baffle 12 downward, and the baffle 12 squeezes the second spring 15. The second spring 15 is compressed and deformed, thereby playing a standing role. When the baffle 12 moves downward, the damping oil 14 moves from one side of the baffle 12 to the other side through the oil hole 13. Since the damping oil 14 is relatively viscous, the baffle 12 moves slowly in the damping oil 14 when it moves. The damping oil 14 not only plays the role of absorbing pressure and buffering shock, but also can prevent the second spring 15 from rebounding back and forth. , plays a damping role. When the height of the air monitoring equipment body 7 needs to be adjusted according to different positions, the worm 21 is rotated. Since the worm 21 is meshed with the worm wheel 20, the worm 21 drives the worm wheel 20 to rotate when it rotates, and the worm wheel 20 drives the shaft 18 to rotate, and the shaft 18 drives the gear 19 to rotate. Since the gear 19 is meshed with the rack 5, the gear 19 has a driving effect on the carrier plate 2. The carrier plate 2 moves along the path of the dovetail groove 27 under the action of the dovetail block 28. The height of the carrier plate 2 is adjusted, and the height of the air monitoring equipment body 7 is indirectly adjusted. The screw rod 23 is rotated, and the screw rod 23 is fed along the path of the threaded hole, and then the screw rod 23 pushes the pressure plate 24, and the pressure plate 24 contacts the column 4. The carrier plate 2 is limited by increasing the pressure to prevent the carrier plate 2 from moving in series.
