When the air duct is used for a long time after installation, the connection part far from the suspension rod may sag due to the gravity of the pipeline itself, resulting in cracks at the connection part and affecting the normal use of the air duct. Summary of the Utility Model

[0006] The effects achieved by the above components are as follows: by setting the support rod, after installing the air ducts and connecting multiple air ducts, the horizontal position of the support rod can be adjusted by pushing the L-shaped rod at the groove rod on the outer surface of one air duct to slide the slider on the inner wall of the groove rod, and then rotating the bolt to make the bolt move downward in the inner wall of the L-shaped rod and abut the bottom end against the top end of the groove rod, fixing the positions of the L-shaped rod and the support rod and the groove rod, so that the support rod is located below the air duct connected to this air duct, and supporting the lower part of the connection of the two air ducts.

[0007] Preferably, a rotating wheel is rotatably connected to one side of the L-shaped rod, and the outer surface of the rotating wheel rotates on the outer surface of the pipe body.

[0008] The effects achieved by the above components are as follows: when the L-shaped rod is pushed to slide the slider on the inner wall of the groove rod, the rotating wheel on one side of the L-shaped rod will rotate on one side of the air duct, further restricting the relative positions between the L-shaped rod and the air duct, and improving the stability of the L-shaped rod when moving.

[0009] Preferably, a positioning block is fixedly connected to one side of the sliding block, and one side of the positioning block slides on one side of the slot rod.

[0010] The effect achieved by the above components is that when the L-shaped rod is pushed to move, one side of the positioning block will slide on one side of the slot rod, further limiting the angle between the L-shaped rod and the slot rod, and avoiding the angle of the L-shaped rod from being deflected as much as possible.

[0011] Preferably, one side of the bottom end of the L-shaped rod is fixedly connected to an inclined rod, and one end of the inclined rod away from the L-shaped rod is fixedly connected to one side of the support rod.

[0013] Preferably, a gasket is fixedly connected to the bottom end of the bolt, and the gasket is made of rubber material.

[0014] The above components have the following effects: the rubber gasket at the bottom of the bolt is pressed against the top of the slot rod by rotating the bolt, so that the position fixation of the slider and the L-shaped rod is more stable and not easy to slide.

[0015] Preferably, a plurality of protrusions are provided on the outer surface of the top end of the bolt, and the protrusions are distributed in a circle on the top end of the outer surface of the bolt.

[0016] The effect achieved by the above components is that the rotation of the bolt can be controlled more conveniently without slipping by holding the protrusion on the outer surface of the top end of the bolt.

[0017] Preferably, a reinforcing device is provided inside the tube body, and the reinforcing device comprises a rectangular plate, both ends of the rectangular plate are fixedly connected with plug rods, and a plurality of slots are provided at the four corners of the inner wall of the tube body.

[0018] The effect achieved by the above components is: when using the air duct, the rods at both ends of a number of rectangular plates can be inserted into two mutually perpendicular slots on the inner wall of the duct body, so that the rectangular plates are located at the corners of the inner wall of the duct body, supporting the internal shape and structure of the duct body and improving the stability of the duct body during use.

[0019] Preferably, a plurality of convex strips are fixedly connected to one side of the rectangular plate, and the convex strips are linearly distributed on one side of the rectangular plate.

[0020] The effect achieved by the above components is that the friction between the hand and the outer surface of the rectangular plate can be increased by pressing the convex strip on the outer surface of the rectangular plate with the hand, and it is more convenient to push or pull the rectangular plate to control the movement of the rectangular plate.

By providing the support rod 24, after connecting multiple air ducts when installing the air duct, the L-shaped rod 23 can be pushed at the groove rod 21 on the outer surface of one air duct, and the slider 22 slides on the inner wall of the groove rod 21 to adjust the horizontal position of the support rod 24, and then the bolt 25 is rotated to make the bolt 25 move downward in the inner wall of the L-shaped rod 23 and abut against the top end of the groove rod 21 to fix the positions between the L-shaped rod 23 and the support rod 24 and the groove rod 21, so that the support rod 24 is located below the air duct connected to this air duct to support the lower part of the connection of the two air ducts. By providing the support device 2, by adjusting the positions of the support rods 24 on both sides of the outer surface of the air duct and fixing the support rods 24 below the connection of the two air ducts to support the lower part of the air duct, it is possible to avoid as much as possible the lower part of the connection of the air duct away from the suspension rod from sagging due to gravity during long-term use of the air duct, which affects the normal use of the air duct.

[0029] Reference Figures 2-3 As shown, in this embodiment: one side of the L-shaped rod 23 is rotatably connected to a rotating wheel 26, and the outer surface of the rotating wheel 26 rotates on the outer surface of the tube body 1. When the L-shaped rod 23 is pushed to slide on the inner wall of the slot rod 21 through the slider 22, the rotating wheel 26 on one side of the L-shaped rod 23 will rotate on one side of the air duct, further restricting the relative position between the L-shaped rod 23 and the air duct, and improving the stability of the L-shaped rod 23 when moving. One side of the slider 22 is fixedly connected to a positioning block 27, and one side of the positioning block 27 slides on one side of the slot rod 21.
