[0028] As shown in Figures 1-5 , in the embodiment: the sides away from each other of the two vertical plates are provided with a locking mechanism 4, the locking mechanism 4 comprises two connecting rods 46 connected with the lifting plate 31, the end portions of the connecting rods 46 inserted into the lifting plate 31 are fixedly connected with rotating discs 47, the rotating discs 47 are located in rotating cavities 34, the rotating cavities 34 are arranged in the lifting plate 31 and gap-fitted with the rotating discs 47; the above-mentioned components achieve the effect that after the lifting plate 31 is moved to the appropriate position, the locking mechanism 4 can lock the lifting plate 31 moved to the position; and when it is needed to move the lifting plate 31, the locking mechanism 4 can be driven to unlock the lifting plate 31, and then the lifting plate 31 can be moved along the lifting cavity 12; after the two connecting rods 46 are inserted into the lifting plate 31, the rotating discs 47 can prevent the connecting rods 46 from being separated from the lifting plate 31; and the rotating discs 47 can rotate along the rotating cavities 34, and the gap-fitted arrangement of the rotating cavities 34 and the rotating discs 47 can make the rotating cavities 34 not affect the rotation of the rotating discs 47.

[0029] As shown in Figures 1-5As shown in this embodiment: two parallel lifting grooves 13 are provided on the outer surface of each upright plate. The lifting grooves 13 are connected to the lifting cavity 12 and extend in a direction parallel to the height direction of the upright plate. The connecting rod 46 is located in the lifting groove 13 and moves along the length direction of the lifting groove 13. The effect achieved by the above components is that the extension direction of the lifting groove 13 is parallel to the height direction of the upright plate. Therefore, during the movement of the lifting plate 31 along the lifting cavity 12, the connecting rod 46 can move up and down along the lifting groove 13 without affecting the normal movement of the lifting plate 31. The setting of the two lifting grooves 13 makes it convenient for both connecting rods 46 to move up and down together with the lifting plate 31.

A rotating handle 45 is fixedly connected to the end of the threaded rod 44 away from the connecting rod 46. The effect achieved by the above components is that the rotation of the two threaded rods 44 can drive the locking plate 41 to move along the length of the threaded rods 44 through the two threaded cylinders 43; the rotating handle 45 can drive the threaded rods 44 to rotate; during the rotation of the threaded rods 44, the connecting rod 46 can rotate along the rotating cavity 34 through the rotating disk 47; the two threaded cylinders 43 are designed for easy replacement. When the internal threads of the threaded cylinders 43 wear down, only the threaded cylinders 43 need to be replaced, without needing to replace the locking plate 41.

The locking plate 41 fixes the position of the lifting plate 31 through the threaded rod 44, the connecting rod 46, and the rotating disk 47. When it is necessary to move the lifting plate 31, the handle 45 is rotated to drive the locking plate 41 away from the upright plate through the threaded rod 44, and the rack 14 separates from the toothed groove 42. Then the lifting plate 31 can drive the locking plate 41 to rise and fall synchronously through the threaded rod 44, the connecting rod 46, and the rotating disk 47. After the lifting plate 31 moves to the appropriate position, the handle 45 is rotated in the opposite direction to make the rack 14 engage with the toothed groove 42, so that the position of the lifting plate 31 can be fixed again.

[0032] The working process of the utility model is as follows: after the air pipe is placed into the inner cavity between the two vertical plates, the baffle 2 is fixed to the two vertical plates to limit the upper end position of the air pipe, then the mounting plate 32 and the lifting plate 31 are fixed on the roof through the mounting bolt 33, then the threaded rod 44 is rotated through the rotating handle 45, the threaded rod 44 drives the locking plate 41 to move away from the direction of the vertical plate side wall through the threaded cylinder 43, in this process, the rack 14 is separated from the gear slot 42, when the rack 14 is completely separated from the gear slot 42, the vertical plate and the lifting plate 31 slide relatively, the height of the air pipe mounting bracket 1 and the air pipe is adjusted, after adjustment, the threaded rod 44 is rotated through the rotating handle 45, the threaded rod 44 drives the locking plate 41 to move to the direction of the vertical plate side wall through the threaded cylinder 43, when the rack 14 is engaged with the gear slot 42, the locking plate 41 is fixed to the vertical plate side wall, the position of the lifting plate 31 is fixed through the locking plate 41, the threaded rod 44, the connecting rod 46 and the rotating disc 47.
