In order to achieve the above object, the present invention also provides an anti-leakage hydraulic joint, including:
the inner surface of the first connecting head is fixedly connected with a first thread, and the outer surface of the first thread is provided with an elastic ring;
the fastening device comprises a support ring, a wedge-shaped strip and a gasket, wherein the right surface of the support ring is fixedly connected with the gasket, and the wedge-shaped strip is fixedly connected with the support ring;
the spring is arranged inside the second connector, the movable plate is fixedly connected to the left end of the spring, the limiting strips are fixedly connected to the left surface of the movable plate, the limiting strips are distributed in an annular mode, and protruding blocks are arranged on the outer surface of the movable plate and are connected with the second connector in a sliding mode.
According to the anti-leakage hydraulic joint, the section of the elastic ring is wedge-shaped, so that the connection effect of the device is improved.
According to the anti-leakage hydraulic joint, the section of each wedge-shaped strip is annular, and the wedge-shaped strips are distributed annularly and are used for being in contact with the limiting strips.
According to an antiseep hydraulic joint, the left surface of second connector is provided with the opening, the cross-section of spacing is the rectangle.
According to the anti-leakage hydraulic joint, a groove is formed in the left surface of the second connector, and corresponds to the gasket in position and is used for improving sealing performance.
According to the antiseep hydraulic joint, the outer surface of the second connector is provided with a second thread.
According to an antiseep hydraulic joint, the material of wedge strip is the stainless steel, the material of spacing strip is copper for convenient to detach, and can not cause two connectors all to appear damaging.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
