A sealing ring 15 is fixedly provided on the side wall of the second joint 3, and a sealing groove 16 matching the sealing ring 15 is opened on the side wall of the first joint 2. The sealing ring 15 can improve the sealing performance in the butt joint state of the first joint 2 and the second joint 3, and prevent seawater from seeping in between the first joint 2 and the second joint 3 and affecting the transportation of oil.

[0027] It also includes:

[0028] Rotating sleeve 4, the rotating sleeve 4 is rotatably sleeved on the first joint 2 through a bearing. Several bolts 5 are rotatably penetrated through the first joint 2 at equal round angles through bearings. Several through grooves 6 are opened on the second joint 3 at equal round angles, and the through grooves 6 are arranged in cooperation with the bolts 5.

[0029] Movable sleeve 7, the movable sleeve 7 is movably sleeved on the second joint 3. Several limit blocks 13 are distributed at equal round angles inside the movable sleeve 7. Several limit grooves 14 are distributed at equal round angles on the second joint 3. The limit blocks 13 are arranged in cooperation with the limit grooves 14. The limit blocks 13 can provide limits to the movable sleeve 7 sleeved on the second joint 3 to prevent the movable sleeve 7 from detaching from the second joint 3. Several internal thread cylinders 8 are distributed at equal round angles inside the movable sleeve 7. One end of the bolt 5 is arranged in cooperation with the internal thread cylinder 8. A spring 12 is movably sleeved on the internal thread cylinder 8. The two ends of the spring 12 are respectively connected to the second joint 3 and the movable sleeve 7. During the butt joint process of the first joint 2 and the second joint 3, the spring 12 can provide a pulling force to the movable sleeve 7 in the direction of the second joint 3 to prevent the phenomenon that one end of the bolt 5 does not contact the internal thread cylinder 8 and idles.

[0030] A ring gear 9 is fixedly arranged inside a rotating sleeve 4. The other end of a bolt 5 is fixedly sleeved with a gear 10. The ring gear 9 is meshed with several gears 10. A compression-resistant component 11 is arranged inside a hose body 1.

[0031] The compression-resistant component 11 includes:

[0032] A first compression-resistant ring 11-1. Several first compression-resistant rings 11-1 are fixedly arranged inside the side wall of the hose body 1.

[0033] A second compression-resistant ring 11-2. Several second compression-resistant rings 11-2 are fixedly arranged inside the side wall of the hose body 1, and the second compression-resistant rings 11-2 are located at the inner side of the first compression-resistant rings 11-1.

[0034] A first compression-resistant rod 11-3. Several first compression-resistant rods 11-3 are respectively and equally rounded and distributed on the inner ring wall of several first compression-resistant rings 11-1. One end of the first compression-resistant rod 11-3 is connected to the second compression-resistant ring 11-2. An inclined second compression-resistant rod 11-4 is connected between two adjacent first compression-resistant rods 11-3. The inclined directions of two adjacent second compression-resistant rods 11-4 are arranged in opposite directions. Two ends of the second compression-resistant rod 11-4 are respectively fixed to the first compression-resistant ring 11-1 and the second compression-resistant ring 11-2. Several first compression-resistant rods 11-3 and several second compression-resistant rods 11-4 can form several triangular support structures between the first compression-resistant ring 11-1 and the second compression-resistant ring 11-2. And by virtue of the stability, pressure resistance and other characteristics of the triangle, the hose body 1 can have stronger compression resistance performance, avoiding the hose body 1 from being compressed by a large amplitude under external force and causing adverse effects on the transportation of oil.

[0035] When using the present utility model, when it is necessary to butt two hose bodies 1, the first connector 2 on the hose body 1 is made to abut against the second connector 3 on another hose body 1. At this time, one end of the bolt 5 passes through the through groove 6 and abuts against the internal thread cylinder 8. And the internal thread cylinder 8 moves away from the second connector 3 under the extrusion of the bolt 5, and drives the movable sleeve 7 to move on the second connector 3 and stretch the spring 12. Then rotate the rotating sleeve 4. The rotating sleeve 4 drives the ring gear 9 to rotate. The ring gear 9 drives several gears 10 to rotate. The gears 10 drive the bolt 5 to rotate, so that one end of the bolt 5 is screwed into the internal thread cylinder 8 through the thread. And the internal thread cylinder 8 approaches the second connector 3. After the internal thread cylinder 8 abuts against the second connector 3, the connection of the two hose bodies 1 is realized.

[0038] 2. Through the first compression ring 11-1 and the second compression ring 11-2, not only the double-layer compression resistance of the inner wall of the hose body 1 can be achieved, but also through the triangular support structure formed by the first compression rod 11-3 and the second compression rod 11-4 between the first compression ring 11-1 and the second compression ring 11-2, the compression resistance performance of the hose body 1 can be greatly improved;

[0039] 3. The limit block 13 can provide a limit for the movable sleeve 7 sleeved on the second joint 3 to prevent the movable sleeve 7 from detaching from the second joint 3;
