Problems solved by technology

Any channel applied to the four-way joint body of the hydraulic hose adopts the design of the same inner diameter. The four-way joint body with the same inner diameter can only be connected to the hose joint in an aligned manner during use, which will cause misalignment. , and the sealing effect is not good. When the hydraulic load increases, there will be gaps in the connection, and oil leakage will occur.

Embodiment Construction

[0010] attached by figure 1 It can be seen that the present invention includes a main body 5, which is composed of four passages: passage I1, passage II2, passage III3 and passage IV4. There are threads on the outside of each passage, that is, the four-way joint body is connected with a hose joint with a nut, and the inner diameter of each passage gradually expands from the inside to the outside, with a flaring design. The four pathways are distributed in a criss-cross manner in the same plane.

[0011] When in use, the inner core of the hose joint with a nut that needs to be connected is first inserted into the passage, and then the nut is tightened. Since each channel is designed with flaring, the hose joint is inserted into the four-way joint body during connection, which not only completely solves the problem of misalignment, but also greatly improves the sealing effect, and there is no need to worry about gaps at the joint when the hydraulic load increases The situation...

Abstract

The invention provides a hydraulic hose four way connection joint body, relates to the hydraulic industry, and is applied to hydraulic device oil way hose joint connection. The hydraulic hose four way connection joint body comprises a body, four passageways, namely passageway I, passageway II, passageway III and passageway IV, are arranged on the body, threads are arranged outside each passageway, the inner diameter of each passageway enlarges from inside to outside gradually to form an expanding opening, and the expansion angle of the expanding opening is 24 degrees minus or plus 30'. The four passageways are in a same level, and are distributed in a criss-cross manner. The hydraulic hose four way connection joint body has the advantages that each passageway is designed with an expanding opening, so that the hose joints are inserted into the four way connection joint body when being connected, the problem of nonalignment is completely solved, sealing effect is greatly improved, the existence of a slit at the connecting part when the hydraulic load increases is avoided, and oil leakage is avoided as well.

Description

technical field [0001] The invention relates to the hydraulic industry and is used for the connection of the oil circuit hose joint of the hydraulic device. Background technique [0002] At present, the connection mode of the four-way joint body of the hydraulic hose is that four passages are distributed in a crossing manner in the same plane. Any channel applied to the four-way joint body of the hydraulic hose adopts the design of the same inner diameter. The four-way joint body with the same inner diameter can only be connected to the hose joint in an aligned manner during use, which will cause misalignment. , and the sealing effect is not good. When the hydraulic load increases, there will be gaps in the connection, and oil leakage will occur. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic hose four-way joint body, which can completely solve the problem of misalignment, increase the degree of sealing, and avoid oil lea...
