Description

Air inlet pipe assembly

Technical Field

The utility model belongs to the technical field of the vehicle accessory, a intake pipe assembly is related to.

Background

The air inlet pipe assembly is mainly used for engine electronic injection control systems of automobiles and motorcycles and is used for providing air inlet and oil inlet channels for the engines. The oil sprayer is an indispensable component in the air inlet pipe assembly, but the existing oil sprayer is generally connected with the air inlet pipe through a stud, the oil sprayer forms a limiting structure through the matching of the stud and a gasket, and a space is reserved between the stud and the oil sprayer, so that slight deviation possibly exists during assembly, and subsequent use is influenced.

Disclosure of Invention

The utility model aims at providing a to the above-mentioned problem that exists among the prior art, provide one kind and prevent that the deviation from appearing and reduce replacement cost's intake pipe assembly in the installation.

The purpose of the utility model can be realized by the following technical proposal: an air inlet pipe assembly comprises an air inlet main body and an oil injection main body, wherein the oil injection main body is arranged on the air inlet main body and connected with the air inlet main body, and an installation platform part which is fixedly connected with the air inlet main body and used for installing the oil injection main body is arranged on the air inlet main body.

In the above air intake pipe assembly, the end face of the oil injection main body located at the corresponding limiting unit is provided with through holes for the screw rod to pass through, a gap is reserved between the screw rod and the corresponding through hole through the limiting unit, and a gasket which is sleeved on the screw rod and prevents the screw rod from moving is arranged between the screw rod and the oil injection main body.

In foretell intake pipe assembly, spacing unit constitute by the adapter sleeve that has the external screw thread and the ring that has the external spline, the ring cover locate the adapter sleeve and link firmly rather than mutually, the oil spout main part be located the inner wall of through-hole department and be provided with the internal spline with external spline matched with.

Compared with the prior art, the air inlet pipe assembly has the following advantages:

1. two threaded holes which are symmetrically arranged are formed in the mounting table portion, the mounting table portion is located at the corresponding threaded hole and is provided with a limiting unit which is connected with the mounting table portion and prevents the oil spraying main body from deflecting after assembly, a screw which is connected with the limiting unit and prevents the oil sprayer from axially moving is arranged on the limiting unit, the oil spraying main body is further limited by the structure, deviation of the oil spraying main body during stud assembly is prevented, meanwhile, abrasion of the mounting table portion in the air inlet main body is reduced, and therefore the service life of the air inlet main body is prolonged, and replacement cost is reduced.
