[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] See also Figure 1-6 , the utility model provides a technical solution:

[0028] A large-caliber HDPE tee profile fixing structure includes a tee profile body 1, wherein the outer surfaces of the three sides of the tee profile body 1 are fixedly connected to first connecting rings 2, the outer sides of the three first connecting rings 2 are each provided with a second connecting ring 3, and the outer surfaces of the three first connecting rings 2 and the second connecting rings 3 are each provided with a plurality of equally spaced connecting holes 10, and further includes:

[0029] Multiple sets of fixing components, each of which is located between the first connecting ring 2 and the second connecting ring 3, and is used to fix the first connecting ring 2 and the second connecting ring 3;

[0030] The sealing connection assembly is located on the outer surface of the first connecting ring 2 and the second connecting ring 3, and is used to enhance the sealing when the first connecting ring 2 and the second connecting ring 3 are connected. The second connecting ring 3 is fixedly connected to other components, thereby achieving the fixation of the three-way profile body 1.

[0031] Furthermore, the fixing assembly includes a connecting column 4, a fixed block 6, a movable block 7 and a connecting shaft 8. The connecting column 4 is inserted into the connecting hole 10 corresponding to the second connecting ring 3. The other end of the connecting column 4 is fixedly connected to the connecting shaft 8. The outer surface of the connecting shaft 8 is movably connected to the movable block 7. The outer surface of the other side of the connecting shaft 8 is fixedly connected to the fixed block 6. The movable block 7 is located between the connecting column 4 and the fixed block 6. The second connecting ring 3 is placed on the outside of the first connecting ring 2 to ensure that the connecting holes 10 of the two are aligned, and then the connecting column 4 is inserted into the second connecting ring 3, until the other end of the connecting column 4 is exposed. Before inserting the connecting column 4, align the movable block 7 with the fixed block 6, so that the movable block 7 and the fixed block 6 enter the corresponding connecting holes 10 of the second connecting ring 3 and the first connecting ring 2 together with the connecting shaft 8. Driven by the connecting shaft 8, the movable block 7 moves toward the fixed block 6. When the movable block 7 is exposed from the connecting hole 10 in the first connecting ring 2, it moves downward under the action of gravity, so that the movable block 7 is engaged with the outer surface of the first connecting ring 2, forming a stable locking structure.

[0032] Furthermore, the diameter of the movable block 7 is equal to the diameter of the fixed block 6. Both the fixed block 6 and the movable block 7 are movable through the corresponding connecting hole 10 of the second connecting ring 3 and extend to the outside of the corresponding connecting hole 10 of the first connecting ring 2. The movable block 7 is clamped with the outer surface of the first connecting ring 2. When disassembly is required, the movable block 7 can be pushed to align with the fixed block 6 again, thereby disengaging from the two connecting holes 10.

[0033] Furthermore, slots 9 are provided on the outer surfaces of the first connecting ring 2 and the second connecting ring 3 that are close to each other, and sealing rings 5 are sleeved on the outer surfaces of the two slots 9. The sealing rings 5 are inserted into the slots 9 to ensure that the sealing rings 5 fit tightly between the two connecting rings to form a preliminary sealing effect.

[0034] Furthermore, the sealing connection assembly includes a first connecting block 11, a second connecting block 12, a clamping column 13 and a clamping block 15. The two ends of the sealing ring 5 are respectively fixedly connected to the first connecting block 11 and the second connecting block 12. The inside of the first connecting block 11 is rotatably connected to the clamping column 13, and the bottom of the clamping column 13 is fixedly connected to the clamping block 15. The clamping column 13 located on the first connecting block 11 is rotated so that the clamping block 15 at its bottom passes through the movable groove 14 located on the second connecting block 12.

[0035] Furthermore, a plurality of equally spaced movable grooves 14 are provided on the outer surface of the second connecting block 12, and the clamping block 15 passes through the corresponding movable grooves 14 and is clamped with the outer surface of the sealing ring 5. After the clamping block 15 passes through the movable grooves 14, the clamping column 13 is rotated again so that the clamping block 15 is clamped with the outer surface of the sealing ring 5. This step further enhances the sealing effect between the sealing ring 5 and the two connecting rings.

[0036] Working principle: When the staff needs to use the large-diameter HDPE tee profile to fix the structure, the second connecting ring 3 is placed on the outside of the first connecting ring 2 to ensure that the connecting holes 10 of the two are aligned, and then the connecting column 4 is inserted into the corresponding connecting hole 10 of the second connecting ring 3 until the other end of the connecting column 4 is exposed. Before inserting the connecting column 4, the movable block 7 is aligned with the fixed block 6, so that the movable block 7 and the fixed block 6 enter the corresponding connecting holes 10 of the second connecting ring 3 and the first connecting ring 2 together with the connecting shaft 8. The movable block 7 moves toward the fixed block 6 under the drive of the connecting shaft 8. When the movable block 7 is exposed from the connecting hole 10 in the first connecting ring 2, it moves downward under the action of gravity, so that the movable block 7 is engaged with the outer surface of the first connecting ring 2, forming a stable locking structure, ensuring a firm connection between the first connecting ring 2 and the second connecting ring 3, and the second connecting ring 3 is fixedly connected to other components. The fixation of the three-way profile body 1 is achieved. When disassembly is required, the movable block 7 can be pushed to align with the fixed block 6 again, thereby disengaging from the two connecting holes 10. Notches 9 are provided on the outer surfaces close to the first connecting ring 2 and the second connecting ring 3 for installing the sealing ring 5. The sealing ring 5 is inserted into the notch 9 to ensure that the sealing ring 5 fits tightly between the two connecting rings to form a preliminary sealing effect. The clamping column 13 on the first connecting block 11 is rotated so that the clamping block 15 at its bottom passes through the movable groove 14 on the second connecting block 12. After the clamping block 15 passes through the movable groove 14, the clamping column 13 is rotated again so that the clamping block 15 is clamped with the outer surface of the sealing ring 5. This step further enhances the sealing effect between the sealing ring 5 and the two connecting rings and prevents leakage of fluid or gas. The first connecting block 11 fits the second connecting block 12, so that the movable groove 14 does not affect the sealing.
