[0002] With the popularity of hose applications, more and more pipe joints are used to connect hoses. In the prior art, a hose joint with an arc-shaped protrusion at the end is often used. Insert it into the inside of the hose to deform the hose, thereby playing the role of connection fixation and sealing. In order to make the connection more firm, the outer end of the connection is often fastened with a clamp. This connection method is not only troublesome to operate in use, but also The pressure is low, and the connection between the pipe joint and the hose is prone to leakage, which brings inconvenience to production and life

The invention discloses an anti-leakage hose joint, which comprises a connecting body. The connecting body is provided with through holes penetrating left and right. The connecting body is provided with an annular groove with an opening at the left end. The annular groove is the same as the through hole. The shaft is set; a ring sleeve is fixedly installed in the annular groove, an inner ring groove is formed between the ring sleeve and the inner circular side of the annular groove, and an inner ring groove is formed between the ring sleeve and the outer circular side of the annular groove in the annular groove. An outer ring groove is formed between them; the inner ring groove is slidably connected with an inner sealing ring pipe, and the outer ring groove is slidably connected with an outer sealing ring pipe; the left end of the inner sealing ring pipe is provided with an inner sealing protrusion, The inner side of the left end of the outer sealing ring pipe is provided with an outer sealing protrusion; the first chamber is formed in the inner ring groove, the second chamber is formed in the outer ring groove, and a flow hole is arranged in the ring sleeve ; An annular intubation groove with an opening at the left end is provided inside the ring sleeve; the hose joint is not only convenient for installation, but also can prevent leakage caused by high pressure.
Description
technical field [0001] The invention belongs to the technical field of pipe joints, in particular to a leak-proof hose joint. Background technique [0002] With the popularity of hose applications, more and more pipe joints are used to connect hoses.
