[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 ,and Figure 5 The utility model provides an embodiment of a ventilation duct that is easy to install, including a fixed platform 1 that serves as an installation load-bearing device, a connecting pipe 2 fixedly connected to the bottom end of the fixed platform 1, a first bidirectional screw 12 rotatably connected to the front end of the connecting pipe 2, a moving block 13 threadedly connected to the front and rear ends of the first bidirectional screw 12, the bottom side of the opposite end of the moving block 13 is rotatably connected to 16, the outer wall of the opposite end of 16 is rotatably connected to the top of the rotating platform 3, the bottom end of the rotating platform 3 is rotatably connected to the first unidirectional screw 4, and the outer wall of the first unidirectional screw 4 is threadedly connected to the lifting platform 5. It includes a rotating plate 6 that is rotatably connected at both ends of the lifting platform 5, and a second toothed ring 18 is fixedly connected to the front and rear sides of the right end of the lifting platform 5. The inner wall of the rotating plate 6 is fixedly connected to a return spring 19, and the other end of the return spring 19 is fixedly connected to the first toothed ring 17. The outer wall of the right end of the first toothed ring 17 is detachably connected to the outer wall of the left end of the second toothed ring 18. The four sides of the outer wall of the rectangular fixed frame 7 are threadedly connected to the second one-way screw 9, and the opposite end of the second one-way screw 9 is rotatably connected to the extrusion plate 10, and a rectangular pipe is installed at the opposite end of the extrusion plate 10.

[0028] Specifically: after the fixing platform 1 is installed on the wall, when the rectangular pipe is installed in the rectangular fixing frame 7, the second one-way screw 9 is rotated to retract along the inner side of the rectangular fixing frame 7, so that the extrusion plate 10 fixes the four sides of the rectangular pipe. If a circular pipe needs to be installed, the adjusting ring 11 is rotated to make the gear ring 14 drive the transmission gear 15 to rotate the second two-way screw 20, so that the moving piece 23 is relatively retracted along the inner side of the circular fixing frame 8, and the traction rods 21 are rotatably connected to each other, so that the moving piece 23 squeezes the traction rod 21 so that the extrusion block 22 fits the circular pipe, thereby clamping the circular pipe. When the rectangular pipe and the circular pipe are clamped, when the rectangular fixing frame 7 and the circular fixing frame 8 need to be folded, the first toothed ring 17 is pressed to retract the return spring 19, so that the first toothed ring 17 falls off from the second toothed ring 18, so that the rotating plate 6 is rotated and adjusted, and the rectangular fixing frame 7 and the circular fixing frame 8 are rotated and folded during actual use, which is convenient for single installation of circular or rectangular pipes.

[0029] Reference Figure 3 and Figure 4 , serving as a clamping and fixing rectangular fixed frame 7 and circular fixed frame 8, the front end of the circular fixed frame 8 is rotatably connected to the adjusting ring 11, the inner wall of the adjusting ring 11 is fixedly connected to the gear ring 14, the rear end of the second bidirectional screw 20 is fixedly connected to the transmission gear 15, the gear ring 14 and the transmission gear 15 are meshedly connected, the front end of the second bidirectional screw 20 is rotatably connected to the front end of the inner wall of the circular fixed frame 8, the front and rear ends of the second bidirectional screw 20 are threadedly connected to the moving piece 23, the opposite end of the moving piece 23 is rotatably connected to the traction rod 21, and the opposite end of the extrusion block 22 is rotatably connected to the outer wall of the opposite end of the front traction rod 21.

[0030] Specifically: the first bidirectional screw 12 drives the moving block 13 to move horizontally along the bottom side of the fixed platform 1, and the moving block 13 uses the connecting component 16 to pull the rotating platform 3 to rotate, thereby realizing flexible adjustment of the direction of the ventilation duct. At the same time, when it is necessary to adjust the height of the lifting platform 5, operate the first unidirectional screw 4 to rotate it, thereby pushing the lifting platform 5 up and down. The movement of the lifting platform 5 also drives the rectangular fixed frame 7 and the circular fixed frame 8 installed thereon to rise and fall synchronously, thereby completing the precise adjustment of the height of the entire pipeline system, ensuring the stability and flexibility of the ventilation duct during the turning and height adjustment process, and meeting the diverse needs in complex installation environments.

[0031] Working principle: After the fixed platform 1 is installed on the wall, when the rectangular pipe is installed in the rectangular fixed frame 7, the second one-way screw 9 is rotated to shrink along the inner side of the rectangular fixed frame 7, so that the extrusion plate 10 fixes the four sides of the rectangular pipe. If a circular pipe needs to be installed, the adjusting ring 11 is rotated to make the gear ring 14 drive the transmission gear 15 to rotate the second two-way screw 20, so that the moving piece 23 shrinks relatively along the inner side of the circular fixed frame 8, so that the moving piece 23 squeezes the traction rod 21 to make the extrusion block 22 fit into the circular pipe, thereby clamping the circular pipe, and the first two-way screw 12 is rotated to make the moving block 13 move along the bottom side of the fixed platform 1, so that the moving block 13 rotates through 16 to pull the rotating platform 3, thereby adjusting the direction of the pipe, and when it is necessary to adjust the height of the lifting platform 5, the first one-way screw 4 is rotated to make the lifting platform 5 drive the rectangular fixed frame 7 and the circular fixed frame 8 to rise and fall.
