However, the fixing bolts will rust and be damaged in the case of long-term use, causing the thread slipping phenomenon, resulting in the loosening of the fixing bolts, affecting the stability of the connection structure. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides an MPP pipeline with a connection structure to solve the above-mentioned technical problems.

[0005] An MPP pipeline with a connection structure comprises a No. 1 pipe body and a No. 2 pipe body, the No. 1 pipe body is provided with a No. 1 external convex connecting ring, the No. 1 external convex connecting ring is provided with a symmetrical installation groove, the installation groove is connected with a sliding clamping block via a reset spring, the sliding clamping block is connected with a limiting block via a rotating shaft, the No. 2 pipe body is provided with a No. 2 connecting ring, the No. 2 connecting ring comprises a reference ring, an extension ring and an external convex limiting ring; the No. 1 external convex connecting ring abuts against the reference ring, the sliding clamping block squeezes the reset spring, the limiting block is rotated in a direction close to the extension ring, and the limiting block abuts against the inner wall of the external convex limiting ring.

[0006] Furthermore, the reference ring is provided with an inner guide groove, and the No. 1 outer convex connecting ring is provided with an insert rod that matches the inner guide groove.

[0007] Furthermore, the limit block is fixedly connected with an L-shaped handle.

[0008] Furthermore, the width of the L-shaped handle is greater than the width of the outer convex limiting ring.

[0009] Furthermore, the width of the No. 1 external convex connecting ring is smaller than the distance from the external convex limiting ring to the outer wall of the No. 2 tube body, and the length of the limiting block is equal to the width of the external convex limiting ring.

[0010] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects of the utility model include:

Under the action of the return spring, the No. 1 external convex connecting ring abuts tightly against the reference ring, so that the end of the No. 1 tube body abuts tightly against the end of the No. 2 tube body stably, and avoids the use of a bolt structure;

[0012] 2) The No. 1 external convex connecting ring is protruding relative to the end of the No. 1 tube body, and the No. 2 connecting ring is protruding relative to the end of the No. 2 tube body. During transportation, they protect the ends of the No. 1 and No. 2 tube bodies to prevent deformation caused by collision of the ends of the tube bodies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, other implementation methods or equivalent replacements obtained by those skilled in the art without creative work are all within the scope of protection of the utility model.

[0019] like Figure 1-4As shown, an MPP pipeline with a connection structure includes a No. 1 pipe body 1 and a No. 2 pipe body 2, the No. 1 pipe body 1 is provided with a No. 1 external convex connection ring 3, the No. 1 external convex connection ring 3 is provided with symmetrical mounting grooves 4, the number of the mounting grooves 4 can be 2 or 4, the mounting grooves 4 are connected with a sliding clamping block 6 through a return spring 5, the sliding clamping block 6 is connected with a limiting block 8 through a rotating shaft 7, the No. 2 pipe body 2 is provided with a No. 2 connection ring, the No. 2 connection ring includes a reference ring 9, an extension ring 10 and an external convex limiting ring 11;

[0020] When connecting the No. 1 tube body 1 and the No. 2 tube body 2, the No. 1 external convex connecting ring 3 enters the space formed by the reference ring 9, the extension ring 10 and the external convex limiting ring 11 and abuts against the reference ring 9. At this time, the end of the No. 1 tube body 1 abuts against the end of the No. 2 tube body 2, and the sliding clamping block 6 is pressed to squeeze the reset spring 5. The limit block 8 is rotated in the direction close to the extension ring 10 to release the pressure on the sliding clamping block 6. The limit block 8 abuts against the inner wall of the external convex limiting ring 11. At this time, the reset spring 5 is still in a tightly squeezed state. Under the action of the reset spring 5, the No. 1 external convex connecting ring 3 abuts tightly against the reference ring 9, and the end of the No. 1 tube body 1 abuts tightly against the end of the No. 2 tube body 2.

[0021] Among them, the reference ring 9 is provided with an inner guide groove 12, and the No. 1 external convex connecting ring 3 is provided with an insert rod 13 which matches the inner guide groove 12. The length of the insert rod 13 = the depth of the inner guide groove 12 - 1 mm. The insert rod 13 enters the inner guide groove 12 until the No. 1 external convex connecting ring 3 is tightly abutted against the reference ring 9. After the insert rod 13 is connected to the inner guide groove 12, the No. 1 external convex connecting ring 3 and the No. 1 tube body 1 are prevented from rotating.

[0022] The limit block 8 is fixedly connected to an L-shaped handle 14, so that the limit block 8 can be rotated by the L-shaped handle 14. The width W of the L-shaped handle 14 is 1 Greater than the thickness H of the outer convex limiting ring 11 1 After the limit block 8 abuts against the inner wall of the outer convex limit ring 11 , the outer end of the L-shaped handle 14 protrudes outside the outer convex limit ring 11 , making it easy to determine the position of the limit block 8 through the protruding L-shaped handle 14 .

[0023] Among them, the width W of the No. 1 outer convex connecting ring 3 is 2 Smaller than the distance S from the outer convex limiting ring 11 to the outer wall of the second tube body 2 1 , the length L of the limit block 8 1 Equal to the width W of the outer convex limiting ring 11 3 .
