Embodiment Construction

[0012] As can be seen from the figure, the present invention includes passageway I4, passageway II3, joint body 2, and passageway III1, wherein the end of passageway III1 is provided with an inner nozzle, and the shape of the inner nozzle is a tapered structure that gradually shrinks toward the end, and its outer wall is extended The angle between the lines is 24°±30′, and an annular groove 6 is provided near the end.

[0013] The connection mode of the hydraulic hose tee joint of the present invention is that passage I4 and passage II3 are connected to the joint body 2 at 90 degrees, and passage II3 and passage III1 are connected to the joint body 2 at 90 degrees, and the three are all on the same plane. The specific structure of the joint body III1 part is divided into the internal structure and the nut. The internal structure includes the beginning of the inner joint 8, the steel wire 7, the annular groove 6, and the end of the inner joint 5. An O-ring is added to the annula...

Abstract

The invention discloses a hydraulic hose tee joint which comprises a joint body, wherein a passageway I, a passageway II and a passageway III are arranged on the joint body, an inner mouthpiece is arranged at the end part of the passageway III, the inner mouthpiece is a cone-shaped structure, and an annular groove is formed in a position close to the end part. Steel wires are arranged at the root part of the inner mouthpiece. The tee joint has the advantages that when the hose is accessed, the cone-shaped design of the inner mouthpiece enables the original alignment communication mode to be changed into a plugging communication mode, an O-shaped rubber ring is placed in the groove, so as to form sealed blocking between the outer wall of the inner mouthpiece and the inner wall of the accessing hose, no slit is formed, the connection mode can completely improve the condition of nonalignment, when the oilway pressure increases, oil injection is prevented due to the seamless plugging mode, so that sealing effect is ideal.

Description

technical field [0001] The invention relates to the hydraulic industry and is applied to the connection of oil circuit hoses of hydraulic devices. Background technique [0002] At present, the hydraulic hose tee joint is composed of a passageway I, a passageway II, a joint body, and a passageway III, wherein the passageway III is composed of an inner nozzle, a steel wire, and a nut. [0003] At present, the connection method of the hydraulic hose tee joint is that passage I and passage II are connected to the joint body at 90 degrees, and passage II and passage III are connected to the joint body at 90 degrees. The three are all on the same plane, and the joint body III The specific structure of the part is divided into internal structure and nut. The internal structure is composed of the beginning of the inner joint --- steel wire --- the end of the inner joint, and the inner structure is covered with nuts. [0004] At present, the inner nozzle part of the hydraulic hose t...
