[0024] The limiting mechanism 5 includes a pressing rod 501, a clamping block 502, a positioning rod 503, and a spring 504; there are two pressing rods 501, which are symmetrically slidably installed on the inner sides of the two support frames 2, and the pressing rod 501 is used to synchronously drive the clamping block 502 to move; the clamping block 502 is fixed at the end of the pressing rod 501 and extends to the inner wall of the support frame 2, and the clamping block 502 is used to provide a limit for the connection of the roof cross bar; the positioning rod 503 is fixed at the outer wall of the pressing rod 501 and extends to the inner wall of the support frame 2, and the positioning rod 503 is used to provide a guide for the movement of the pressing rod 501; the two ends of the spring 504 are respectively clamped on the inner wall of the support frame 2 and the outer wall of the positioning rod 503, and the spring 504 is used to provide a reset elastic force for the positioning rod 503 after movement.

[0025] The transmission unit includes a first rack 601, a gear 602, a second rack 603, and a rotating shaft 604; the first rack 601 is fixed to the outer wall of a pressing rod 501 and extends to the inside of the bottom end of the detection body 1, and the first rack 601 is used to give the gear 602 a rotational thrust; the gear 602 is rotatably installed on the inner wall of the bottom end of the detection body 1, and the gear 602 is used to push the second rack 603 to move axially; the second rack 603 is fixed to the outer wall of another pressing rod 501, and the second rack 603 is used to drive the other pressing rod 501 to move; the rotating shaft 604 is vertically fixed at the top axial position of the gear 602 and extends to the inside of the detection body 1, and the rotating shaft 604 is used to provide support for the rotation of the gear 602.

[0026] The limiting unit includes a rotating rod 605, a detection rod sleeve 606, and a limiting groove 607; the rotating rod 605 is fixed on the outer wall of the rotating shaft 604, and the rotating rod 605 is used to cooperate with the limiting groove 607 to limit the height of the detection rod sleeve 606; the detection rod sleeve 606 is vertically slidably installed inside the positioning sleeve 3, and the top of the detection rod sleeve 606 is connected to a detection head 4 for collecting air quality data, and the detection rod sleeve 606 is used to drive the detection head 4 to move synchronously; the limiting groove 607 is opened on the outer wall of the detection rod sleeve 606, and the limiting groove 607 is used to provide space for the docking of the rotating rod 605.

[0027] In this embodiment: when the detection body 1 needs to be installed, the detection body 1 is placed on the roof cross bar, and the cross bar is aligned with the docking groove through the docking groove opened on the support frame 2. At this time, the pressing force can be applied to the pressing rod 501, and the pressing rod 501 will drive the positioning rod 503 to move synchronously and apply extrusion force to the spring 504. At the same time, the moving pressing rod 501 synchronously drives the clamping blocks 502 fixed at both ends to move, so that the clamping blocks 502 move from the docking groove to the inside of the support frame 2. At this time, the cross bar can be aligned with the docking groove at the bottom of the support frame 2.

[0028] At the same time, when the pressing rod 501 is pulled, the movement of the pressing rod 501 will also synchronously drive the movement of the first rack 601. The axially moving first rack 601 will give rotational power to the gear 602, and the rotating gear 602 will push the second rack 603 to move axially, so that the second rack 603 gives thrust to the other pressing rod 501, so that the two pressing rods 501 move away from each other. Then, the clamping blocks 502 fixed at both ends of the other pressing rod 501 will also enter the interior of the support frame 2, which is convenient for the synchronous clamping or disassembly of the cross bar on the other side, further improving the assembly efficiency.

[0029] While applying the pressing force to the pressing rod 501, the rotating gear 602 will also synchronously drive the rotating shaft 604 with a fixed axis position to rotate, so that the rotating rod 605 fixed on the outer wall of the rotating shaft 604 will also rotate counterclockwise with the rotation angle of the gear 602, so that the rotating rod 605 moves out from the inner side of the limiting groove 607, and the vertical movement of the detection rod sleeve 606 is no longer performed. At this time, the detection rod sleeve 606 can be pulled to move, and the height of the detection rod sleeve 606 can be adjusted to facilitate the detection head 4 to perform mobile detection on different height areas. After the adjustment is completed, the pressing force can be no longer applied to the pressing rod 501, so that the pressing rod 501 is reset by the elastic force from the spring 504, the inclined surface of the clamping block 502 is against the roof cross bar, and the rotating rod 605 will also rotate clockwise again to dock with a limiting groove 607, and the height of the detection rod sleeve 606 is limited and fixed.

[0030] Please refer to Figure 1-Figure 5 There are multiple limit grooves 607, which are evenly distributed on the outer wall of the detection rod sleeve 606. The outer wall of the rotating rod 605 matches the inner wall of the limit groove 607. The detection rod sleeve 606 is within the rotation trajectory of the rotating rod 605. The interior of the detection rod sleeve 606 is connected to the detection head 4 and the controller inside the detection body 1 through a wire. The interior of the detection body 1 is provided with sliding grooves for the first rack 601 and the second rack 603 to slide.

[0031] In this embodiment: through this structure, after the height of the detection rod sleeve 606 is adjusted, the rotating rod 605 can be synchronously driven to rotate again by resetting the pressing rod 501 and the first rack 601, and engage with a limiting groove 607 to limit and fix the detection rod sleeve 606.

[0032] Please refer to Figure 1-Figure 5 The bottom end of the support frame 2 is formed with a docking groove for docking with the roof cross bar, the clamping block 502 is located on one side of the docking groove, the outer wall of the clamping block 502 is inclined, and the inner wall of the support frame 2 is formed with a sliding groove for the clamping block 502 to slide.

[0033] In this embodiment: through this structure, the clamping block 502 can be brought into contact with the outer wall of the roof cross bar under the action of the inclined surface of the clamping block 502, and the clamping convenience and connection force between the clamping block 502 and the roof cross bar are increased through the inclined outer wall.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
