[0002] PVC pipes are generally of a simple single-layer structure, which results in insufficient structural strength and cannot meet the usage requirements in various scenarios. For double-layer PVC pipes, due to the poor firmness after the connection of the inner pipe and the outer pipe, misalignment is likely to occur between the inner and outer pipes, and the structure also has insufficient strength. Therefore, we propose a phosphogypsum composite PVC diamond-shaped multi-purpose pipe and its manufacturing process to solve the problems mentioned in the above background art.

A second steel wire rope 17 is connected between the third support frame 4 and the fourth support frame 7. The right end of the first steel wire rope 18 and the left end of the second steel wire rope 17 are connected with a convex head 3;

[0032] On the upper and lower surfaces of the left and right ends of the inner tube 2, connection seats 8 are provided. The connection seats 8 are movably connected with clamping plates 9 through pin shafts 10. The clamping plates 9 are clamped in corresponding clamping grooves 19 on the inner wall of the installation cavity 16. The left end of the first steel wire rope 18 and the right end of the second steel wire rope 17 are fixed to the upper sides of the corresponding clamping plates 9;

[0033] The connection head includes an insertion pipe 12 inserted into the gap between the diamond-shaped outer tube 1 and the inner tube 2 through both ends and a limit frame 13 at the end of the insertion pipe 12. A raised block 15 inserted into the inside of the connection seat 8 is provided on the insertion pipe 12. The limit frame 13 is fixed to both ends of the diamond-shaped outer tube 1 through screws 14.

[0034] Specifically, the first support frame 6, the second support frame 5, the third support frame 4, and the fourth support frame 7 and the inner tube 2 are integrally formed.

[0035] Specifically, the first support frame 6, the second support frame 5, the third support frame 4, and the fourth support frame 7 are arranged at equal intervals.

[0036] Specifically, the outer sides of the first support frame 6, the second support frame 5, the third support frame 4, and the fourth support frame 7 are closely attached to the inner wall of the installation cavity 16.

[0037] Specifically, a rubber sealing frame 11 is sleeved on the outer side of the insertion pipe 12. The rubber sealing frame 11 is clamped between the diamond-shaped outer tube 1 and the limit frame 13.

[0038] Specifically, the limit frame 13 and the insertion pipe 12 are integrally formed.

[0039] A manufacturing process of a phosphogypsum composite PVC diamond-shaped multi-purpose pipe specifically includes the following steps:

[0040] S1. Move the first steel wire rope 18 and the second steel wire rope 17 towards each other through the raised head 3, so that the first steel wire rope 18 and the second steel wire rope 17 invert the corresponding clamping plates 9 towards the surface of the inner tube 2;

[0041] S2. Then insert the inner tube 2 into the installation cavity 16, so that the outer sides of the first support frame 6, the second support frame 5, the third support frame 4, and the fourth support frame 7 are closely attached to the inner wall of the installation cavity 16;

[0042] S3. Insert the insertion pipe 12 into the gap between the diamond-shaped outer tube 1 and the inner tube 2 through both ends, and then fix the limit frame 13 of the connection head to both ends of the diamond-shaped outer tube 1 through screws 14;

[0043] S4. The convex block 15 is inserted into the inside of the connecting seat 8, so that the convex block 15 abuts against the clamping plate 9, causing the clamping plate 9 to rotate around the pin shaft 10 until the clamping plate 9 tightly straightens the corresponding first steel wire rope 18 and the second steel wire rope 17. At the same time, the clamping plate 9 is stuck in the corresponding card slot 19 on the inner wall of the installation cavity 16.

[0044] In summary, compared with the prior art, the insertion pipe 12 of the present invention is inserted into the gap between the diamond-shaped outer pipe 1 and the inner pipe 2 through both ends, and then the limit frame 13 of the connector is fixed to both ends of the diamond-shaped outer pipe 1 by screws 14. The convex block 15 is inserted into the inside of the connecting seat 8, so that the convex block 15 abuts against the clamping plate 9, causing the clamping plate 9 to rotate around the pin shaft 10 until the clamping plate 9 tightly straightens the corresponding first steel wire rope 18 and the second steel wire rope 17. At the same time, the clamping plate 9 is stuck in the corresponding card slot 19 on the inner wall of the installation cavity 16;

[0045] With the arrangement of the first steel wire rope 18 and the second steel wire rope 17, after the first steel wire rope 18 and the second steel wire rope 17 are tightly straightened, a triangle is formed between them and the diamond-shaped outer pipe 1, so that the first steel wire rope 18 and the second steel wire rope 17 can tightly hold the middle part of the inner pipe 2, making the inner pipe 2 not easily deformed;

[0046] The clamping plate 9 is stuck in the corresponding card slot 19 on the inner wall of the installation cavity 16, so that the inner pipe 2 can be firmly fixed inside the diamond-shaped outer pipe 1, preventing the inner pipe 2 from generating axial displacement;

[0047] With the arrangement of the first support frame 6, the second support frame 5, the third support frame 4 and the fourth support frame 7, and the outer sides closely adhering to the inner wall of the installation cavity 16, the support between the inner pipe 2 and the diamond-shaped outer pipe 1 is better.
