Abstract
The utility model belongs to the field of devices for connecting oil pipes with steering boxes of cars, and particularly relates to a structure for connecting an oil pipe with a steering box of a car. The structure comprises a metal copper pipe for being connected with the steering box, a circle of protrusions are arranged on the pipe neck of the metal copper pipe, a hollow nut with external threads is sleeved on the outer surface of the metal copper pipe and welded and fixed with the metal copper pipe by silver fibers, the hollow nut abuts against the protrusions, connecting flaring is formed in the end portion of the metal copper pipe, at least one groove is formed in the hollow nut, an ejection rod is connected via a blot pin inside the groove, one end of a compression spring is connected to the ejection rod, and the other end of the compression spring is connected with the bottom of the groove. The structure has the advantages that the top rod is supported by the compression spring, so that the nut can be prevented from falling after being connected; the sealing performance of the pipe can be improved through an O-shaped ring in the flaring, and stability of the pipe and driving safety are improved.
Description
Technical field
The utility model belongs to the connection set field of automobile oil pipe and steering box, specifically a kind of automobile oil pipe steering box linkage structure.
Background technique
Automobile oil pipe has three kinds substantially, and gasoline pipe is to connect petrol pump and engine nozzle, is used to provide fuel oil.Also have power-assisted oil pipe, for steering box provides power-assisted oil, thereby reach the object that alleviates steering drag.Brake oil pipe is to connect brake pump and brake block fore-set, and when we step on brake, brake pump can be by brake oil to brake block pressure, two brake block extruding brake discs, thus reach the object that car deceleration stops.
Automobile oil pipe connecting structure is mostly at steel tube head and connects a moulding joint at present, this moulding joint is to be processed by the once-through of metal forming machinery, steel pipe inserts in the circular groove on forming head, and they are welded together, connecting head utilizes hollow bolt to connect, and such linkage structure easily causes bolt falling and then oil pipe to pull in the time of automobile bumpiness, uses dangerous, especially brake oil pipe, is being related to occupant's safety.
Summary of the invention
The utility model is for the deficiency existing in above-mentioned technology, proposes a kind of structural stability, safe automobile oil pipe steering box linkage structure.
The utility model provides following technological scheme:
Automobile oil pipe steering box linkage structure, it comprises that one for connecting the metal copper pipe of steering box, tube neck at metal copper pipe is provided with a circle projection, one be provided with externally threaded hollow nut be socketed between metallic copper tube outer surface and metal copper pipe, by silver-alloy brazing, connect fixing, hollow nut props up projection, metallic copper tube end forms connection enlarging, described hollow nut is provided with at least one groove, in groove, by pin, connect a push rod, the one end that connects Compress Spring on push rod, Compress Spring the other end connecting groove bottom.
Described enlarging inwall is provided with at least one circle groove, is provided with O type circle in groove.
The utility model has the advantages that by Compress Spring, supporting push rod can prevent from coming off after nut from connecting, in enlarging simultaneously, O type circle can improve the sealing of pipeline, has strengthened stability and the drive safety of pipeline.
