With the development of society, insulation pipelines have been widely used, so the demand for insulation pipelines has also increased significantly.

[0003] The existing heat supply pipeline system usually adopts a threaded connection method. However, after long-term use, thread leakage may occur, and factors such as thermal expansion and contraction at the connection will accelerate the wear and aging of the threaded connection, making it easy for cracks to occur at the connection, thereby affecting the sealing performance and reliability of the entire heat supply system.

However, after long-term use, thread leakage may occur, and factors such as thermal expansion and contraction at the connection will accelerate the wear and aging of the threaded connection, making it easy for cracks to occur at the connection, thereby affecting the sealing performance and reliability of the entire heat supply system.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A heat supply pipeline connection assembly includes a first heat supply pipe and a second heat supply pipe. The first heat supply pipe is movably connected to the right side of the second heat supply pipe. A heat preservation pipe is sleeved on the right side of the surface of the first heat supply pipe.

The butterfly nut is threadedly connected to the top of the surface of the screw rod, and the bottom surface of the butterfly nut is movably connected to the top of the first clamping plate.

[0007] Preferably, on both sides of the left side of the first clamping plate and both sides of the left side of the second clamping plate are fixedly connected with clamping blocks. A bolt is arranged on the outer side of the clamping block, and one end of the bolt away from the clamping block is movably connected with the surface of the heat preservation pipe.

[0008] Preferably, a through groove is formed in the front side of the top of the first clamping plate, and the bottom of the through groove penetrates through to the front side of the bottom of the second clamping plate.

[0011] Preferably, a protective sleeve is fixedly connected to the surface of the heat preservation pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1.

[0014] 2. By arranging the fixing mechanism, the first clamping plate and the second clamping plate are sleeved on the surface of the heat preservation pipe. Then, the butterfly nut rotates through the screw rod in a threaded manner and approaches the top of the first clamping plate.

The through hole 405 is opened on the front side of the top of the first clamping plate 401. The bottom of the through hole 405 penetrates to the front side of the bottom of the second clamping plate 402. The screw rod 404 is movably connected to the bottom inside the through hole 405 through a shaft pin. The butterfly nut 403 is threadedly connected to the top of the surface of the screw rod 404. The bottom surface of the butterfly nut 403 is movably connected to the top of the first clamping plate 401.

[0023] As a technical optimization solution of the present utility model, by setting the fixing mechanism 4, the first clamping plate 401 and the second clamping plate 402 are sleeved on the surface of the heat preservation pipe 3, and then the butterfly nut 403 is rotated threadedly through the screw rod 404 to approach the top of the first clamping plate 401. After that, the bottom of the butterfly nut 403 is attached to the top of the first clamping plate 401, so as to fix the first clamping plate 401 and the second clamping plate 402 to clamp the heat preservation pipe 3.

[0024] Reference Figure 3 , clamping blocks 5 are fixedly connected to both sides on the left side of the first clamping plate 401 and both sides on the left side of the second clamping plate 402. Bolts 6 are arranged on the outer sides of the clamping blocks 5, and one end of each bolt 6 away from the clamping block 5 is movably connected to the surface of the heat preservation pipe 3.

[0025] As a technical optimization solution of the present utility model, by setting the clamping blocks 5 and the bolts 6, the bolts 6 are rotated to pass through the clamping blocks 5 and contact the surface of the heat preservation pipe 3, and then the bolts 6 fix the heat preservation pipe 3.

[0026] Reference Figure 3 , a through groove 7 is formed in the front side at the top of the first clamping plate 401, and the bottom of the through groove 7 penetrates through to the front side at the bottom of the second clamping plate 402.

[0028] Reference Figure 3 , a fixing block 8 is fixedly connected to the top of the screw rod 404.

[0029] As a technical optimization solution of the present utility model, by setting the fixing block 8, the fixing block 8 blocks the butterfly nut 403 from rotating away from the screw rod 404 through the bolt 6, so as to limit the movement of the butterfly nut 403.

At the same time, the butterfly nut 403 moves towards the top of the screw rod 404 through the threaded rotation of the bolt 6, and then the screw rod 404 rotates from inside the through groove 7 through the pin shaft, so that the first clamping plate 401 can be quickly disassembled.
