The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described in the following can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 4, in an embodiment of the present invention, an internal thread lockable hose connector includes a mounting head 1 and a connector main body 2, an internal thread module 21 is fixedly disposed on an upper side of the connector main body 2, and the connector main body 2 is connected to an external thread on a lower side of the mounting head 1 through the internal thread module 21; the joint body 2 is used for sealing a connection hose, and the mounting head 1 is used for sealing a connection device.

It should be noted that the joint body 2 adopts internal threads, so that the hose with strong mobility can be better aligned to the mounting head 1 on the equipment, and can be better fastened in a rotating manner; compared with an external thread structure, the connector body 2 adopting the internal thread structure wraps the accessory between the connector body 2 and the mounting head 1, so that a flow path is lengthened, the sealing performance is improved, meanwhile, the threaded connection between the connector body 2 and the mounting head 1 plays a role in one-layer sealing, and the sealing performance is stronger.

The lower side of the mounting head 1 is also provided with a core sleeve 11; a plurality of inclined grooves 12 are uniformly distributed on the inner side of the mounting head 1, and a plurality of limit inclined plates 13 are arranged on the core sleeve 11 corresponding to the grooves 12; the core sleeve 11 is further provided with a first limit table 14, and the first limit table 14 is used for limiting the position of the mounting head 1 relative to the core sleeve 11 in the vertical direction.

It should be noted that, in some embodiments, the position-limiting inclined plate 13 on the core sleeve 11 may be matched with the groove 12 inside the mounting head 1 to realize the position-limiting connection between the mounting head 1 and the core sleeve 11, so that the core sleeve 11 may rotate along with the mounting head 1, and the inclined position-limiting inclined plate 13 and the groove 12 may make the assembly between the core sleeve 11 and the mounting more appropriate, so that the rotation is more effective, the connection is more stable and more convenient and labor-saving; at the same time, the first limit table 14 also improves the sealing property between the mounting head 1 and the core sleeve 11

An annular groove 15 is formed in the lower side of the core sleeve 11, and a lining 16 is arranged in the annular groove 15; the bush 16 is provided with a second limit table 17, and the second limit table 17 is used for limiting the position of the bush 16 in the vertical direction relative to the core sleeve 11 and keeping the inner diameters of the bush 16 and the core sleeve 11 consistent.

It should be noted that the inner diameters of the bushing 16 and the core sleeve 11 are the same, so that the flow of the fluid can be more smooth and stable, the impact force of the fluid on the fitting inside the joint body 2 can be avoided, and the service life of the fitting can be prolonged. The second limit table 17 also makes the connection between the core sleeve 11 and the bushing 16 tighter and has stronger sealing performance.

A plurality of inclined notches 18 are uniformly formed on the lower side of the core sleeve 11.

The inner side of the internal thread module 21 is also provided with an inclined table 22, and the inclined table 22 is abutted with the bushing 16.

It should be noted that, during the process of screwing the mounting head 1 and the joint body 2 through the threaded connection, the mounting head 1 applies pressure to the bushing 16 through the core sleeve 11, so that the bushing 16 is tightly abutted to the inclined table 22 of the female screw module 21, which not only makes the connection more stable, but also greatly improves the sealing performance.

Still be provided with sealing washer 23 in the joint main part 2, the inboard of sealing washer 23 is provided with the sealed line of multilayer fastening, and the sealed line of fastening is used for fastening sealed hose. The sealing ring 23 can connect and seal the hose and ensure that the connection of the hose is more stable and is not easy to move and fall off.

The downside equipartition that connects main part 2 has a plurality of square holes 24, connects main part 2 and is connected with jack catch 25 through square hole 24, and jack catch 25 is used for the quick installation dismantlement of hose. The jack catch 25 further carries out spacing fixed to the hose, avoids the not hard up stability and the leakproofness that influences the internal connection of card pipe.

The mounting head 1 is further provided with a first sealing ring 26, the first sealing ring 26 being used to seal the connection between the mounting head 1 and the joint body 2.

A second sealing ring 27 is also provided in the mounting head 1, the second sealing ring 27 being intended to seal the connection between the mounting head 1 and the equipment.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
