Description
Technical Field
The utility model relates to an automobile parts technical field specifically indicates an oil filler hole notes oil pipe seal structure.
Background
The position degree of the oiling pipe of car oil tank port on the side wall panel beating plane is very unreliable, often can deviate theoretical position by a wide margin, and this problem often is difficult to solve from the oiling pipe angle, and the difficulty that meets includes that the reference column welding position tolerance of oiling system is difficult to guarantee, spacing not enough, the size chain overlength of oiling pipe etc..
At present, a plurality of schemes for solving the problem of lap joint between the soft rubber hole and the counterpart piece exist, and firstly, the interference amount between the soft rubber hole and the complex is increased; secondly, the lapping position of the soft rubber hole and the complex is set to be invisible; thirdly, abandoning the lapping, and enlarging the soft rubber hole to form another type of model. The second and third ideas are optimal on the premise of being supported by the modeling department, so that the problems are fundamentally eliminated; the concept of one involves a solution that is directly related to the individual considerations of the engineer and requires manpower to make a targeted adaptation. At present, the standardization of an interface is not realized, and considerable manpower and material resources are wasted in the adaptation process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects existing in the prior art, and providing a sealing structure of an oil filling pipe of an oil filling port, which has simple structure and high sealing performance and is favorable for standardization.
In order to achieve the purpose, the utility model provides an oil filler hole oiling pipe seal structure which characterized in that, including setting up the sealed flexible glue between oiling pipe and oiling mouth casing, the transversal L type that personally submits of sealed flexible glue, sealed flexible glue with oiling mouth casing fixed connection, sealed flexible glue is leaned on oiling pipe one end is continuous wave, the oiling pipe endotheca in the sealed flexible glue and with wave tip interference fit.
Preferably, the wave shape comprises an arc-shaped groove and an arc-shaped protrusion.
Preferably, the arc-shaped groove is close to one side of the oil filling pipe, and the slope of the arc-shaped groove is greater than that of the arc-shaped bulge.
Preferably, the wavy end part is a sealing end surface, an included angle between the sealing end surface and the oil filling pipe is 20-40 degrees, and a reinforcing protrusion is arranged at the tail end of the sealing end surface.
The utility model has the advantages that: simple structure, high sealing performance and easy standardization. One end of the soft sealing glue close to the oil filling pipe is designed into a continuous wave-shaped fold, so that the elastic deformation capacity of the soft sealing glue in the cross section direction is increased, and the positioning tolerance of the oil filling pipe in the cross section direction is easier to adsorb; the included angle between sealed terminal surface and the notes oil pipe is 20 ~ 40 and the end sets up strengthens the arch, but the contact surface of sealed terminal surface and notes oil pipe is laminated more, and the leakproofness is good, and whole seal structure is simple, is favorable to the standardization.
Drawings
FIG. 1 is a perspective view of a fuel filler seal.
FIG. 2 is a cross-sectional view of a fuel filler seal.
FIG. 3 is a schematic view showing the combination of the soft sealing rubber and the oil filling pipe.
The components in the figures are numbered as follows: the sealing structure comprises a sealing soft rubber 1, a sealing end face 101, an arc-shaped groove 102, an arc-shaped protrusion 103, a reinforcing protrusion 104, an oil filling pipe 2, an oil filling port shell 3, a bottom plate 301, a buckle 302, a side wall metal plate 4 and a clamping groove 401.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in figures 1-3, a fuel filler neck seal structure, including setting up the sealed flexible glue 1 between fuel filler neck 2 and fuel filler neck casing 3, evenly be equipped with buckle 302 on the fuel filler casing 3, side wall panel beating 4 evenly is equipped with draw-in groove 401 around the fuel filler neck, buckle 302 and draw-in groove 401 joint, the transversal L type that personally submits of sealed flexible glue 1, sealed flexible glue 1 and fuel filler neck casing 3 vulcanize fixedly, sealed flexible glue 1 is continuous wave by fuel filler neck 2 one end, 2 endotheca of fuel filler neck are in sealed flexible glue 1 and with wavy tip interference fit, like this, continuous wave fold has increased the elastic deformation ability of sealed flexible glue on the cross section direction, thereby adsorb the tolerance of fuel filler neck on the cross section direction more easily.
Preferably, the wave shape includes an arc-shaped groove 102 and an arc-shaped protrusion 103, the arc-shaped groove 102 is located on the filler pipe 2 side, and the slope of the arc-shaped groove 102 is greater than that of the arc-shaped protrusion 103. If the number of the wave-shaped structures is too large, the wave-shaped structures are easy to be extruded and bent, if the number of the wave-shaped structures is too small, the elastic deformation capacity is insufficient, and the wave-shaped structures are formed by an arc-shaped groove and an arc-shaped bulge, so that the wave-shaped structures are not easy to bend and can resist the elastic deformation; the wave slope of leaning on oiling pipe one side is greater than and keeps away from oiling pipe one side for lean on oiling pipe one side and receive the extrusion more easily and warp when just contacting, thereby adsorb the positioning error of oiling pipe, keep away from oiling pipe one side and then can keep certain resistance deformability, make the butt power between wavy tip and the oiling pipe bigger, the laminating is inseparable.
Preferably, the wavy end part is a sealing end surface 101, the included angle between the sealing end surface 101 and the oil filling pipe 2 is 20-40 degrees, and the tail end of the sealing end surface 101 is provided with a reinforcing bulge 104. The included angle is set to be 20-40 degrees and is not too large or too small, preferably set to be 30 degrees, if the included angle is too large, the sealing end face tends to be a plane, the effect of absorbing position tolerance is poor, and the problems of wrinkling, eversion, non-lamination and the like can occur on the upper part of the soft rubber when the soft sealing rubber deforms. If the angle is too small, the sealing soft rubber and the oil injection pipe are changed from line contact to surface contact, the absorption of the position tolerance in the cross section direction is not facilitated, and the phenomena of non-lamination and wrinkling are easily caused due to local deformation of the soft rubber. The arrangement of the reinforcing protrusion can enhance the deformation resistance of the tail end of the sealing end face, and the sealing end face is not easy to extrude and too large in bending, so that the phenomenon that the sealing end face is not attached is avoided.
