Abstract

The invention discloses an adjustable multifunctional combined joint structure. The adjustable multifunctional combined joint structure comprises a main transition joint and a connecting joint. The main transition joint comprises a thin nut body and a transition body, the transition body is of a cylindrical structure, the thin nut body is coaxially connected with the transition body, and the thinnut body comprises an internal thread. The connecting joint comprises a connecting body and a connector, the connector is connected with the connecting body in the radial direction of the connecting body, the connecting body comprises a transition hole, the transition body is arranged in the transition hole in a penetrating manner, and the connecting joint can rotate by 360 degrees with the transition body as the axis. According to the adjustable multifunctional combined joint structure, free adjustment of a pipeline joint in the 360-degree direction, connector reserving and sealing of a composite sealing gasket can be achieved. The adjustable multifunctional combined joint structure can meet the requirement for multi-pipeline connection, meanwhile, the edge cutting phenomenon of an O-shaped ring cannot be caused, locking torque can be guaranteed, and sealing reliability is guaranteed.

Description

technical field [0001] The invention relates to the field of engines, in particular to an adjustable and multifunctional combined joint structure. Background technique [0002] With the gradual upgrade of technology and emissions, the cooling system of the whole vehicle is getting more and more water from the engine (such as the heating system of the whole vehicle, the heating system of the SCR after-treatment pipeline, the heating system of the LNG carburetor, and the heating of the CNG high-pressure reducer) system). Due to the different pipeline layouts of different automobile factories and the limited space for engine installation and adjustment, the intake and return water joints need to meet the requirements of any installation angle, and at the same time ensure the sealing reliability. The existing joints are all in the form of a single joint due to space constraints. The layout of the vehicle pipeline is messy and not compact; the original joints and lock nuts are d...
