[0033] One end of the contraction part 6 and the diffuser 7 are both flange structures, and the other end thereof is provided with a docking end 8. The diameter of the docking end 8 is equal to the diameter of the throat 1. A number of docking blocks 9 are fixedly connected to the surface thereof. The docking block 9 is L-shaped, and a threaded groove 10 is provided on the surface of each docking block 9. A positioning seat 11 is installed at the bottom of the contraction part 6 and the diffuser 7. The two sides of the positioning seat 11 are L-shaped, and a card groove 12 is provided on the top surface thereof. The card groove 12 is arc-shaped, and a mounting hole 13 is provided at the bottom of the groove. When the positioning seat 11 is installed at the bottom of the contraction part 6 and the diffuser 7, the bottom of the contraction part 6 and the diffuser 7 can be fitted in the card groove 12, and the bottom plane of the positioning seat 11 is in contact with the contact surface such as the ground. At this time, the contraction part 6 and the diffuser 7 can be supported by the positioning seat 11 respectively to play a role of positioning and fixing, which effectively avoids the rolling and displacement of the venturi tube during transportation, which causes collision and wear on its surface.

[0034] Among them, the end cross-section of the docking block 9 is a rectangle, and its width and thickness are respectively equal to the length and width of the docking port 3, and the center of each docking block 9 corresponds to the center of each docking port 3. When the contraction portion 6 and the diffuser portion 7 are attached to the two ends of the throat 1, each docking block 9 can be aligned with and pass through the corresponding docking port 3 respectively. At this time, the docking work of the contraction portion 6 and the diffuser portion 7 can be completed through the mutual cooperation between the docking block 9 and the docking port 3.

[0035] Among them, the inner wall surface of the threaded groove 10 is engraved with an internal thread that matches the bolt 5, and its diameter is equal to the diameter of the threaded hole 4, and the center of each threaded groove 10 corresponds to the center of each threaded hole 4. After each docking block 9 passes through the corresponding docking port 3, the bolt 5 in the threaded hole 4 can be tightened, and the end of the bolt 5 can be screwed into the corresponding threaded groove 10. At this time, the contraction part 6 and the diffusion part 7 can be fixed at the two ends of the throat 1 respectively through the mutual cooperation between the threaded hole 4, the bolt 5 and the threaded groove 10 to complete the installation of the entire Venturi tube. By unscrewing the bolt 5, the contraction part 6 and the diffusion part 7 can be removed from the two ends of the throat 1, so that the internal area of ​​each part of the Venturi tube can be easily cleaned and maintained. In addition, when the Venturi tube fails, each part can also be replaced separately.

[0036] Among them, the bottom of the contraction part 6 and the diffusion part 7 are fixedly connected with a mounting column 14, the column surface of the mounting column 14 is engraved with an external thread, and a nut 15 matching it is threadedly connected thereto, and the diameter of the mounting column 14 is equal to the diameter of the mounting hole 13, and the mounting column 14 can be aligned with and pass through the corresponding mounting hole 13. At this time, the nut 15 is threadedly connected to the mounting column 14 and tightened, and the positioning seat 11 can be fixed to the bottom of the contraction part 6 and the diffusion part 7 respectively through the mutual cooperation between the mounting column 14, the mounting hole 13, and the nut 15. By unscrewing the nut 15, the positioning seat 11 can be removed from the contraction part 6 and the diffusion part 7 for cleaning and maintenance.

[0037] Among them, a layer of anti-skid pad 16 is provided on the bottom surface of both sides of the positioning seat 11, and the surface of the anti-skid pad 16 is engraved with a herringbone anti-skid pattern. The anti-skid pad 16 is made of elastic material such as rubber and is fixed by glue or other means. When the bottom of the positioning seat 11 contacts the contact surface, the anti-skid pattern on the surface of the anti-skid pad 16 can increase the friction between the positioning seat 11 and the contact surface to play an anti-skid role, thereby further improving the stability of the venturi tube during transportation and effectively avoiding its slipping and displacement.

[0038] Among them, reinforcing ribs 17 are fixedly connected to both sides of the positioning seat 11. The reinforcing ribs 17 are triangular block structures, and their bottoms are fixedly connected to the bottom of the positioning seat 11. The positioning seat 11 can be reinforced by the reinforcing ribs 17 to enhance the structural firmness of the positioning seat 11, thereby effectively preventing the positioning seat 11 from being deformed due to force.

[0039] Among them, a sealing ring 18 is sleeved on the butt end 8, the inner diameter of the sealing ring 18 is equal to the outer diameter of the butt end 8, and a sealing ring 19 is provided on the inner wall surface of the sealing ring 18. The sealing ring 19 is made of elastic material such as rubber and is fixed by glue or other means. When the contraction part 6 and the diffusion part 7 are completed and fixed at both ends of the throat 1, the sealing ring 18 can be sleeved on the butt end 8 and the throat 1. At this time, the sealing ring 19 can effectively fill the gap between the butt end 8 and the throat 1 to play a sealing role, thereby effectively preventing the fluid from overflowing from the gap.

The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0042] The working principle of the utility model is:

[0043] When the utility model is in use, the contraction part 6 and the diffusion part 7 can be docked at the two ends of the throat 1 respectively. After docking, the contraction part 6 and the diffusion part 7 can be fixed at the two ends of the throat 1 respectively through the mutual cooperation between the threaded hole 4, the bolt 5 and the threaded groove 10 to complete the installation of the entire venturi tube. After the venturi tube is used for a long time, the contraction part 6 and the diffusion part 7 can be removed from the two ends of the throat 1 by unscrewing the bolt 5, so that the internal area of ​​each part of the venturi tube can be easily cleaned and maintained. In addition, when the venturi tube is damaged, the contraction part 6 and the diffusion part 7 can be removed from the two ends of the throat 1. When a failure occurs, each part can be replaced separately. When the Venturi tube needs to be transported, the positioning seat 11 can be installed at the bottom of the contraction part 6 and the diffusion part 7 respectively, so that the bottom of the contraction part 6 and the diffusion part 7 fit in the card groove 12, and the bottom plane of the positioning seat 11 is in contact with the contact surface such as the ground. At this time, the contraction part 6 and the diffusion part 7 can be supported by the positioning seat 11 respectively to play a role in positioning and fixing, effectively avoiding the rolling and displacement of the Venturi tube during transportation, which may cause collision and wear on its surface.
