[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A metal steel pipe and corrugated hose connector, such as Figure 1-4As shown, the connector connects the metal steel pipe and the corrugated hose, and the connector includes a connector 1, both ends of which are fixedly connected with a clamping cover 2, the clamping cover 2 is provided with an internal thread, and the outer side of the clamping cover 2 is provided with an array of anti-slip grooves 21.

[0024] A rubber gasket 3 is fixedly provided in the connector 1, and the rubber gasket 3 is arranged at both ends of the connector 1. A connecting hole 12 is arranged in the connector 1, and a retaining ring 13 is arranged on one side of the connector 1. The retaining ring 13 abuts against one end of a rubber gasket 3, and one end of the other rubber gasket 3 abuts against one side of the connecting hole 12. Threaded pipes 14 are fixedly connected to both ends of the connector 1. The two threaded pipes 14 are used to connect metal steel pipes or corrugated hoses respectively, and the threaded pipes 14 are fixedly connected to the internal threads of the tightening cover 2.

[0025] A through hole 22 is provided at one end of the clamping cover 2, and the through hole 22 is used to be sleeved on a metal steel pipe or a corrugated hose to limit the metal steel pipe and the corrugated hose, thereby ensuring the installation stability of the connected metal steel pipe or corrugated hose link and ensuring the coaxiality of the metal steel pipe or the corrugated hose.

[0026] A round block 33 is fixedly provided at one end of the rubber gasket 3 , and the round block 33 is located inside the rubber gasket 3 . A protrusion 31 is fixedly connected to the other end of the rubber gasket 3 , and the protrusion 31 is located at the end of the threaded tube 14 . A clamping ring 32 is fixedly provided inside the rubber gasket 3 .

[0027] The protrusion 31 abuts against the inner side of the clamping cover 2, and the protrusion 31 on the rubber gasket 3 is pressed and fixed by the clamping cover 2, so that the clamping ring 32 in the rubber gasket 3 is fixed to the outer side of the metal steel pipe or corrugated hose, which is used to lock the metal steel pipe or corrugated hose.

[0028] After the clamp ring 32 is connected to the metal steel pipe or corrugated hose, it has the effect of sealing and waterproofing, so that two different types of pipes can be well fastened and sealed, solving the problem that the metal steel pipe or corrugated hose is inconvenient to fix, improving the aesthetics of the use environment and the waterproof sealing performance of the equipment, and increasing the service life and life of the cables inside the pipe.
