Oil filling port box assembly

Abstract

The invention belongs to the technical field of automobile part manufacturing and particularly discloses an oil filling port box assembly which comprises an oil filling port box, an oil filling pipe, an oil filling pipe guide sleeve and an oil filling pipe constraint sleeve, wherein the upper end of the oil filling pipe guide sleeve is correspondingly connected with an oil inlet of the oil filling port box, the oil filling pipe constraint sleeve is in matched connection with the inner wall of the upper end of the oil filling pipe guide sleeve, and the oil filling pipe is in matched connection with the lower part of the inner wall of the oil filling pipe constraint sleeve, so as to realize sealed assembling of the oil filling pipe and the oil filling port box, so that the accumulated water of the oil filling port box can be effectively prevented from permeating from each overlapping part of the oil filling pipe and the oil filling port box, and the market quality risk that an automobile side inner cavity is rusted due to poor sealing and water leakage can be avoided. In addition, bolt connection is not needed in the whole assembling processes, so that the accumulated water is prevented from permeating in an automobile through a gap between a bolt and a bolt hole; and no bolt is exposed, so that the molded surface is simple and beautiful.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, and in particular relates to a fuel filler box assembly. Background technique [0002] Such as figure 1 As shown, the connection between the existing filler box 1 and the filler pipe 14 is that the upper end of the rubber sleeve 15 of the filler pipe mounting seat 15 is connected with the filler pipe 14, and the lower end thereof is welded to three holes on the outer wall of the filler pipe 14 with projection welding. The bottom surface 13 of the filler pipe mounting seat of the nut, the wheel house outer plate and the fuel filler box 1 overlaps face to face, and is connected together by three bolt holes 12 corresponding to the projection welding nuts and bolts. The connection between the fuel filler box 1 and the filler pipe 14 has the following four disadvantages: 1) when the car is washed or in rainy weather, the accumulated water inside the fuel filler box will infiltrate th...
