Label declaration
Lid 1, boss 11, center tube 12, air filter paper post 2, cover core 3, boss 31, centre porosity 32, edge pore 33, outer cylinder 34, oil filling pipe 4, oil scale 5, screw rod 51, pin 6, oil baffle 7, through hole 71, centre pipe 72, flange 73, setscrew nut 8.
Embodiment
As shown in Figures 1 to 5, a kind of fuel door with ventilating mechanism that the utility model discloses, comprises lid 1, air filter paper post 2, cover core 3, oil filling pipe 4 and oil scale 5.
Lid 1 is locked with cover core 3.
Air filter paper post 2 location are arranged between lid 1 and cover core 3, specifically can form respectively boss 11 and 31 at the opposing side of lid 1 and cover core 3, air filter paper post 2 is enclosed within location on the boss 11 and 31 of lid 1 and cover core 3, and is locked by the power that locks between lid 1 and cover core 3.
On cover core 3, form centre porosity 32 and edge pore 33, cover core 3 enclosing covers are located at oil filling pipe 4 upper ends.In order to ensure that cover core 3 and oil filling pipe 4 closely cooperate, the below of cover core 3 forms the outer cylinder 34 with tapering, cover core 3 coordinates with oil filling pipe 4 by outer cylinder 34 and enclosing cover is located on oil filling pipe 4, the tapering of outer cylinder 34 is conducive to positioning and guiding, and realize the drive fit of cover core 3 and oil filling pipe 4, and then ensure the sealing effect of this fitting surface, to guarantee that ambient air reaches filtering effect by way of air filter paper post 2.
Oil filling pipe 4, together with fuel tank welding, ensures sealing.
The upper end of oil scale 5 is fixed on lid 1 or cover core 3, and this embodiment specifically forms center tube 12 below lid 1, and center tube 12 is through the centre porosity 32 of cover core 3, and the upper end of oil scale 5 is plugged on center tube 12 and by pin 6 and fixes.The stage casing of oil scale 5 is screw rod 51.
Oil baffle 7 empty sets are at the epimere of oil scale 5, and oil baffle 7 be Spielpassung with oil scale 5, make oil baffle 7 can be on oil scale 5 freedom up and down.For ease of assembly, this embodiment's oil baffle 7 forms centre pipe 72 and wears for oil scale 5, centre pipe 72 can make oil baffle 7 up and down more reposefully on oil scale 5, and the upper end A of centre pipe 72 and B place, lower end form respectively rounded surface, is conducive to the up of oil baffle 7 and falls after rise.After oil baffle 7 floatings, enclosing cover is located at oil filling pipe 4 lower ends, and this embodiment forms flange 73 in the top surface edge of oil baffle 7, and the outer wall C of this flange 73 and the inwall D of centre pipe 72 are provided with tapering, are conducive to casting or punching press.This embodiment is also the conical surface at the upper surface E of oil baffle 7, downward-sloping toward center from edge, is conducive to guide fluid to be back to oil baffle 7 centre pipes 72, and it is lubricated, and is conducive to freely up and falling of oil baffle.On oil baffle 7, form through hole 71, the best mode of through hole 71 is to be radial to be uniformly distributed, contribute to the outflow of fluid, and through hole 71 is upper shed greatly and the little circular cone form of under shed, large diameter upper shed is relative with oil filling pipe 4, be convenient to air and enter, the under shed of minor diameter can stop oil gas loose outward, is convenient to oil gas and is cooled to fluid and returns to fuel tank.
Setscrew nut 8 is locked on screw rod 51.The position of oil baffle 7 can keep off oil require according to reality and adjust setscrew nut 8 and determines, by the adjusting to setscrew nut 8, applicable to the different oil level lines of the car of different tonnages.Oil level line is high, upwards regulates oil baffle 7, and oil level line is low, can regulate according to actual needs shift plate 7 downwards.Setscrew nut 8 can directly be bought on market, for cost-saving, preferably as shown in the figure, adopt two traveling nuts to be screwed in together and combines, and also can realize location, and cost is lower simultaneously.The positioning and locking of double nut also can be realized anti-loosing effect, simple installation, and positioning and locking is reliable.
The utility model structural design novelty, increased a floating type installation, position is adjustable and with the oil baffle 7 of through hole 71, oil baffle 7 and the spacing of oil filling pipe 4 can be adaptive to be returned the severe degree of oily phenomenon and automatically adjusts, thereby can solve well the oily problem of returning of fuel door.Road conditions are bad, when vehicle body vibration amplitude is larger, return oily problem more serious, also can effectively solve oil and spatter, return oily problem.
As shown in Figure 3, in the time returning oily situation, oil baffle 7 can be under the thrust of fluid, along the axial direction of oil scale 5, close to oil filling pipe 4, and along with the dwindling of gap between oil filling pipe 4 and oil baffle 7, has prevented that fuel tank from returning the generation of oily phenomenon.Wherein, the size in gap between oil filling pipe 4 and oil baffle 7, is adaptive to fluid and returns the size of oily thrust.As shown in Figure 1, in the time returning oily phenomenon and stop, 7 of oil baffles, under the lubrication of self gravitation and fluid, along the axial direction of oil scale 5, fall back to its initial position.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
