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

Referring to fig. 2-4, the present invention provides an embodiment: a quick connector comprises a main body part 1, a tracheal tube 4 connected with one end of the main body part 1; the gas pipe sleeve 4 is fixed in the main body part 1 through a limiting ring 3; the other end of the main body part 1 is connected with a connecting body 2.

Through the technical scheme, under the condition that the existing structure main body is not changed, the device transfers the original structure and size prefabricated on the main body part 1 to the limiting ring 3, and at the moment, the structure which is consistent with the structure of the limiting ring 3 does not need to be prefabricated in the main body part 1, so that the main body part 1 is more convenient to machine, and the machining process and the machining cost of the main body part 1 are greatly reduced;

meanwhile, through the technical scheme, the limiting ring 3 can be machined outside, so that the size measurement and high-precision machining of the whole structure are facilitated, and the sealing performance of the air pipe sleeve 4 connected with the main body part 1 is better; and the main body part 1 and the limiting ring 3 are convenient to process, so that the manufacturing cost of the device is reduced.

Because still be equipped with in the main part 1 and be used for fixing the fixed slot 7 of spacing ring 3 makes the spacing ring 3 can be stable be located in main part 1 for one time, avoids its slip to lead to the sealing performance of connecting to reduce, and secondly, processing and the preparation of fixed slot 7 are for processing and the preparation with spacing ring 3 prefabrication in main part 1, and the processing of fixed slot 7 is simpler, convenient.

The baffle plate 8 for promoting the expansion of the end part of the trachea sleeve 4 is also arranged in the main body part 1; when the gas pipe sleeve 4 is extruded by external force, the baffle plate 8 causes the end part of the gas pipe sleeve 4 to expand outwards along the outer surface of the baffle plate 8, so that an external pipeline is simple and convenient to insert, and the pipeline is simple and convenient to pull out.

In order to further improve the sealing performance of the device after being connected with a pipeline, the main body part 1 is also internally provided with a ring groove 9 for placing the first sealing ring 5, and the ring groove 9 is close to the connecting body 2.

Because the end of the main body part 1 connected with the connecting body 2 is also provided with a supporting surface 11 and an annular bulge 12; the center of the supporting surface 11 and the center of the annular protrusion 12 are on the same axis, so that the connecting body 2 is more stable after being connected with the main body part 1.

Meanwhile, in order to further facilitate the connection between the two and improve the sealing capability after the connection between the two, one surface of the annular protrusion 12 is used for supporting the second sealing ring 6 arranged on the connecting body 2, and the other surface of the annular protrusion 12 is abutted to the connecting part 10 arranged on the connecting body 2.

And the connecting body 2 is used for attaching one surface of the connecting part 10 facing the main body part 1 to the supporting surface 11 in a reaming and expanding riveting mode.

Because the main body part 1 and the connector 2 are connected by adopting a reaming and expanding riveting process, namely, the connector 2 is arranged at one end of the main body part 1, and then the inner hole at the bottom of the connector 2 and the outer circumference thereof are expanded by punching and expanding through a die so that the outer circumference thereof is clamped in the groove of the main body part 1 to realize the connection of the two,

through above-mentioned connected mode, not only can guarantee main part 1 and connector 2 firm in connection to connector 2 can 360 degrees rotations in main part 1, thereby make things convenient for the installation of the two more and with being connected of outside pipeline.

In order to guarantee that the connector 2 can not lead to the problem that the both drops because of the junction insecure connection with main part 1 after connecting, the cross section of annular protrusion 12 is the rectangle, because the cross section of annular protrusion 12 is the rectangle, consequently utilizes plane and planar contact, enlarges the area of contact of annular protrusion 12 and connecting portion 10, and then promotes the reliability of connecting, annular protrusion 12 can enlarge again and second sealing washer 6 area of contact simultaneously, consequently can further promote the sealing performance that the two are connected again.

Because the limiting ring 3 is movably connected with the main body part 1, the structure greatly reduces the processing difficulty of the main body part 1, and the important size in the structure is easy to measure, thereby ensuring the overall quality, improving the quality and processing efficiency of the product and reducing the product cost; wherein, the spacing ring 3 can be riveted to the inside of the main body part 1 in a riveting manner.

Because the main body part 1 is arranged in an L shape or a straight shape, and the main body part 1 is made of iron, copper, plastic or stainless steel, the requirements of connection of various pipelines can be met, for example, the L shape can realize right-angle butt joint of the pipelines; the horizontal pipeline can be butted in a straight shape; the material of the main body 1 can be customized according to the requirement.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
