Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0018] Reference Figure 1-2A heat preservation structure of an energy-saving steam direct buried pipeline comprises a first pipeline body 1 and a second pipeline body 2. A heat preservation tube 3 is movably inserted outside the first pipeline body 1. A supporting ring plate 4 which abuts against the heat preservation tube 3 is fixedly sleeved outside the first pipeline body 1. A fixing ring plate 5 which abuts against the end of the heat preservation tube 3 is fixedly sleeved on the outer wall of the second pipeline body 2. A plurality of L-shaped locking plates 6 are symmetrically clamped on the outer wall of one end of the heat preservation tube 3 close to the fixing ring plate 5. The vertical part of the L-shaped locking plate 6 is blocked outside the fixing ring plate 5. The L-shaped locking plate 6 and the fixing ring plate 5 are fixedly clamped by a clamping mechanism.

[0019] A plurality of plug-in posts 7 are evenly and fixedly connected to the side wall of the supporting ring plate 4 , and a plurality of plug-in holes 8 matching and plugging with the plug-in posts 7 are provided at the rear end of the heat-insulating cylinder 3 .

[0020] The side wall of the fixed ring plate 5 is fixedly connected with a sealing insert 9 inserted in the heat preservation tube 3 , and the outer side of one end of the sealing insert 9 away from the fixed ring plate 5 is set as a conical expansion structure.

[0021] A T-shaped clamping block 10 is fixedly connected to the outer wall of the heat-insulating cylinder 3 , and a T-shaped clamping groove 11 matching and clamping with the T-shaped clamping block 10 is formed on the inner side of the horizontal portion of the L-shaped locking plate 6 .

[0022] The clamping mechanism includes a clamping rod 12 which is movably inserted into the vertical part of the L-shaped locking plate 6, and the side wall of the fixed ring plate 5 is provided with a clamping groove 13 which matches and is inserted into the clamping rod 12.

[0023] One end of the plug-in post 7 away from the abutting ring plate is configured as a round head structure.

[0024] The operating principle of the utility model is now described as follows:

[0025] When the present application is used, the first pipe body 1, the second pipe body 2 and the insulation tube 3 are provided. After the first pipe body 1 and the second pipe body 2 are assembled, the insulation tube 3 is slid outside the first pipe body 1 so that one end of the insulation tube 3 extends to the outside of the second pipe body 2, and the inner side of one end of the first pipe body 1 abuts against the supporting ring plate 4, and at this time, the other end of the insulation tube 3 abuts against the outside of the fixed ring plate 5, and a stable connection between the insulation tube 3 and the fixed ring plate 5 is achieved through a sealing insert 9, and a stable and accurate connection is achieved between the insulation tube 3 and the supporting ring plate 4 through the matching plug-in column 7 and the plug-in hole 8. The L-shaped locking plate 6 is connected and then stably connected to the insulation tube 3 through the matching engagement of the T-shaped block 10 and the T-shaped slot 11. At this time, the vertical portion of the L-shaped locking plate 6 is blocked outside the fixed ring plate 5 to achieve limited locking of the insulation tube 3. At this time, the clamping rod 12 is aligned with the clamping slot 13, and the clamping spring 15 pulls back the clamping pull plate 14. The clamping pull plate 14 pushes the clamping rod 12 into the clamping slot 13 to achieve a stable clamping and fixing of the L-shaped locking plate 6, thereby ensuring the structural stability and enabling quick disassembly and assembly, so that the connection between the two sections of the pipeline also has good insulation performance and is easy to use.
