A main sleeve 6-4 and a secondary sleeve 6-5 are fitted and connected at both ends of the tubing 1. A connecting lug 6-6 is provided at both ends of the outer surface of the main sleeve 6-4 and the secondary sleeve 6-5. An internally threaded tube 6-7 is provided at the bottom of the connecting lug 6-6 at both ends of the secondary sleeve 6-5. A pair of first screws 6-8 are inserted into the connecting lug 6-6 at both ends of the main sleeve 6-4. The first screws 6-8 are screwed into the internally threaded tube 6-7. The tubing 1 is filled with a steel wire layer 6-9.

[0037] In some examples, to achieve a secure connection, a wrapping assembly 6 is designed. An inner wrapping layer 6-1 and an outer wrapping layer 6-2 are provided at both ends of the tubing 1. A rotary connector 2 and a mating connector 3 are respectively connected to the inner wrapping layer 6-1 at both ends of the tubing 1. A connecting sleeve 6-3 is fitted onto the outer wrapping layer 6-2, fitting against the surface of the tubing 1, for connecting the rotary connector 2 and the mating connector 3 to the tubing 1.

Multiple internally threaded tubes 6-7 are provided on the bottom connecting ears 6-6. A first screw 6-8 is installed on the top connecting ear 6-6 for screwing into the internally threaded tubes 6-7, tightening the main sleeve 6-4 and the secondary sleeve 6-5, and further securing the connecting sleeve 6-3. A steel wire layer 6-9 is filled inside the tubing 1 to enhance its strength.

[0038] like Figures 1-4 As shown, this embodiment proposes a locking assembly 7 including a pair of notches 7-1. The notches 7-1 are formed at opposite ends of the outer surfaces of the rotary connector 2 and the mating connector 3. A threaded bottom groove 7-2 is formed in the notch 7-1. A limit rod 7-3 is inserted into the notch 7-1. Both ends of the surface of the limit rod 7-3 are provided with grooves 7-4. The grooves 7-4 are countersunk structures. A second screw 7-5 is inserted into the groove 7-4. The second screw 7-5 is screwed into the threaded bottom groove 7-2.

[0039] In some examples, in order to achieve the effect of keeping the rotary connector 2 and the butt joint 3 fixed after butt joint, the locking assembly 7 is designed, two slots 7-1 are arranged on the surfaces of the rotary connector 2 and the butt joint 3, and a threaded bottom groove 7-2 is arranged inside, after the rotary connector 2 and the butt joint 3 are connected through the inner thread layer 4 and the outer thread layer 5, the number of threads is the same, the two slots 7-1 can be kept in the same position, a limiting rod 7-3 is arranged in the slot 7-1, two grooves 7-4 are arranged on the surface of the limiting rod 7-3, a second screw 7-5 is inserted into the groove 7-4 and screwed into the threaded bottom groove 7-2.

[0041] In some examples, through the tooth-shaped protrusion, the protruding part extrudes the connecting sleeve 6-3, and the sealing effect is enhanced.

[0042] For example, as shown in Figure 1 The connecting ears 6-6 at both ends of the main sleeve 6-4 are higher than the bottom end faces.

[0043] In some examples, through the higher position, the spacing between the connecting ears 6-6 is increased, the tension when the first screw 6-8 is connected with the inner threaded pipe 6-7 is increased, and the connection strength of the main sleeve 6-4 and the secondary sleeve 6-5 is higher.

[0044] For example, as shown in Figure 1 The outer surface of the rotary connector 2 is provided with a screw protruding layer 8, and the screw protruding layer 8 is a polygonal structure.

[0045] In some examples, through the polygonal screw protruding layer 8, it is convenient to clamp and screw the rotary connector 2 to rotate using a tool.

[0046] When splicing is needed, the rotary connector 2 and the butt joint 3 are respectively adhered to the inner cover layer 6-1 of the rubber tube 1 at both ends, the connecting sleeve 6-3 is sleeved on the outside of the rubber tube 1 in advance, after installation, the main sleeve 6-4 and the secondary sleeve 6-5 are wrapped on the connecting sleeve 6-3, the first screw 6-8 is screwed into the inner threaded pipe 6-7 through the connecting ears 6-6, and is tightened and fixed.
