[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 、 Figure 3 and Figure 5 , an embodiment provided by the present utility model: a directly buried corrugated compensator, including a bellows 1, a first connecting pipe 12 is fixedly connected to the outside of the bellows 1, a second connecting pipe 13 is arranged on the left side of the left first connecting pipe 12, a plug pin 14 penetrates through the inside of the first connecting pipe 12, a limit block 15 is fixedly connected to the left end of the plug pin 14, a card slot 16 is opened in the inside of the second connecting pipe 13, a card block 17 is fixed to the middle side of the outside of the plug pin 14, the upper and lower ends of the card block 17 are slidably connected to a fixed rod 18, a turntable 20 is fixedly connected to the left end of the fixed rod 18, the turntable 20 is arranged on the outside of the plug pin 14, a spring two 19 is arranged on the outside of the fixed rod 18, and the spring two 19 is arranged inside the card block 17 and the turntable 20. An anti-settlement component is arranged on the outside of the bellows 1, and the anti-settlement component is used for preventing settlement of the bellows 1;

[0027] By pressing the bolt 14, the bolt 14 drives the clamping block 17 to move, and then the clamping block 17 can slide on the fixed rod 18. The movement of the clamping block 17 squeezes the second spring 19, causing the second spring 19 to be compressed and stressed. Then, the bolt 14 is rotated, so that the bolt 14 can drive the limiting block 15 to rotate, so that the limiting block 15 can rotate inside the clamping groove 16. The rotation of the bolt 14 can drive the turntable 20 to rotate inside the first connecting pipe 12 through the fixed rod 18. Then, the part on the turntable 20 can rotate through the ball 21, thereby reducing the resistance when the turntable 20 rotates. Then, the bolt 14 is pulled, so that the bolt 14 can drive the limiting block 15 to disengage from the clamping of the clamping groove 16, so that the first connecting pipe 12 and the second connecting pipe 13 can be quickly disassembled, thus improving the maintenance efficiency.

[0028] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0029] When settlement occurs during use, the first spring 5 can bear the weight for it through the support plate 7. When the corrugated pipe 1 is no longer bearing weight, the first spring 5 resets and can lift the corrugated pipe 1, thereby preventing the corrugated pipe 1 from settling. The limiting sleeve rod 6 is composed of a sleeve and a telescopic rod.

[0030] Refer to Figure 1 、 Figure 6 and Figure 7 As shown in FIGS.

[0031] By sleeving two protective casings 8 on the outer surface of the flange 2 and fixing them with fixing bolts 10, the heat-insulating layer 11 can effectively play a heat-insulating role for the compensator. At the same time, the protective casing 8 can play a role in protecting and dust-proofing the compensator. By internally thread-connecting the fixing bolts 10 in the thread grooves 22, the protective casing 8 can be installed outside the corrugated pipe 1. By arranging the balls 21 to assist in rotating the turntable 20 and the limiting block 15 sliding inside the clamping groove 16, the first connecting pipe 12 and the second connecting pipe 13 can be quickly disassembled, thereby improving the maintenance efficiency. By the insertion pin 14 sliding inside the turntable 20, the limiting block 15 can be driven to disengage from the clamping of the clamping groove 16. By arranging the rust-proof coating 23 and the anti-corrosion coating 24, the situation of rusting and corrosion of the protective casing 8 can be effectively avoided. By the clamping block 17 sliding inside the first connecting pipe 12, the spring two 19 can be compressed and stressed.

[0032] Working principle: When using this device, when it is necessary to disassemble and maintain the corrugated pipe body 1, by pressing the insertion pin 14, the insertion pin 14 drives the clamping block 17 to move, so that the clamping block 17 can slide on the fixed rod 18, and the movement of the clamping block 17 will squeeze the spring two 19, so that the spring two 19 can be compressed and stressed. Then rotate the insertion pin 14, so that the insertion pin 14 can drive the limiting block 15 to rotate, so that the limiting block 15 can rotate inside the clamping groove 16, and the rotation of the insertion pin 14 can drive the turntable 20 to rotate inside the first connecting pipe 12 through the fixed rod 18, so that the turntable 20 can rotate through the balls 21, thereby reducing the resistance when the turntable 20 rotates. Then pull the insertion pin 14, so that the insertion pin 14 can drive the limiting block 15 to disengage from the clamping of the clamping groove 16, so that the first connecting pipe 12 and the second connecting pipe 13 can be quickly disassembled, thereby improving the maintenance efficiency. By sleeving two protective casings 8 on the outer surface of the flange 2 and fixing them with fixing bolts 10, the heat-insulating layer 11 can effectively play a heat-insulating role for the compensator. At the same time, the protective casing 8 can play a role in protecting and dust-proofing the compensator. When settlement occurs during use, the spring one 5 can bear the weight through the support plate 7. When the corrugated pipe 1 is no longer bearing weight, the spring one 5 resets and can lift the corrugated pipe 1, thereby preventing the corrugated pipe 1 from settling.
