Abstract
The utility model discloses an oil filling pipe cover with an electricity discharge device, belonging to the technical field of oil filling pipe covers. The oil filling pipe cover comprises an outer cover made of conductive material and a screw shell arranged below the outer cover. An electricity discharge device which is conductive and corresponds with the nozzle of the oil filling pipe is arranged at the inner side of the lower part of the outer cover. The electricity discharge device protrudes towards the oil filling pipe and an electricity discharge gap is left therebetween. Compared with the prior art, the oil filling pipe cover is simple and reasonable in structure, and while preventing fuel oil leakage of a sealed fuel oil tank, the oil filling pipe cover can automatically release the static voltage difference through the electricity discharge mechanism according to the load static voltage of the oil filling pipe in the oil tank to enable the static voltage difference to be balanced and stable, thereby making the oil filling pipe cover safer and more reliable in use.
Description
Technical field
The utility model relates to the fuel filler pipe lid, relates in particular to a kind of fuel filler pipe lid with discharging structure.
Background technology
At present, known fuel filler pipe lid is to have frenulum, rivet, conduction enclosing cover, rubber seal, screw shell assembling to be formed by connecting.Fuel filler pipe after assembling lid is screwed in the fuel filler pipe oral area, utilize the leak tightness of rubber seal that the fuel filler pipe lid is screwed the leak free effect of playing.As application number is that 200520099041.7 Chinese utility model patent discloses the multi-purpose vehicle(MPV) fuel tank locking cap, is made up of dustproof part, induction part, lock portion and safe exhaust portion branch.Dustproof part is made up of cover of dust, rubber cradle, housing, spring etc., and induction part is made up of vacuum valve, O-ring seals, vacuum valve spring etc., and lock portion is made up of lock core, vacuum valve seat, jump ring, locking plate, locking plate seat etc.Housing top is cone, and the bottom is the garland cylinder.But all there is a problem in existing fuel filler pipe lid: fuel filler pipe is in use accumulated static, and conventional fuel filler pipe covers can not carry out release electrostatic to the vehicle fuel pipe after screwing, when object contacts the generation arcing distance with fuel filler pipe when, if the electrostatic potential of accumulative total is excessive, contact process will produce electrostatic spark, especially when the hot gasoline of weather when evaporation is revealed, the spark of generation will be lighted gasoline and bring dangerous.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of simple and reasonable, safe and practical, the fuel filler pipe lid with discharging structure that can release electrostatic.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of fuel filler pipe lid with discharging structure, comprise the enclosing cover of making by conductive material and be arranged on screw shell under the enclosing cover, the lower inside of enclosing cover is provided with discharging structure corresponding with the fuel filler pipe mouth of pipe, that can conduct electricity, discharging structure has discharging gap between the two to the direction projection of fuel filler pipe.
Preferably, above-mentioned discharge mechanism comprises at least one column convex body.
Preferably, above-mentioned discharge mechanism comprises at least one sheet convex body.
Preferably, above-mentioned discharge mechanism is looped around fuel filler pipe mouth of pipe annular convex all around.
In order to obtain better technique effect, further technical measures also comprise:
The width of above-mentioned discharging gap is 0.5 millimeter to 0.8 millimeter.
Above-mentioned discharge mechanism is connected with the enclosing cover one.
The threaded portion root of above-mentioned screw shell is arranged with rubber seal.
Compared with prior art, the utility model comprises the enclosing cover of being made by conductive material and is arranged on screw shell under the enclosing cover, the lower inside of enclosing cover is provided with discharging structure corresponding with the fuel filler pipe mouth of pipe, that can conduct electricity, discharging structure has discharging gap between the two to the direction projection of fuel filler pipe.Owing to be provided with discharging structure in the enclosing cover inboard, when the electrostatic potential on the fuel filler pipe and outside when having load electrostatic potential difference between the electrostatic potential that covers, discharging gap can discharge according to the voltage extent.Therefore, the utility model can be when the sealing fuel tank prevents that fuel oil from leaking, it is poor to carry out the automatic release electrostatic potential by discharge mechanism with the height of the load electrostatic potential of fuel filler pipe in the fuel tank, reach the balance and stability of electrostatic potential difference, make the fuel filler pipe lid in use more safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail:
As shown in the figure, a kind of fuel filler pipe lid with discharging structure, comprise the enclosing cover of making by conductive material 1 and be arranged on screw shell 2 under the enclosing cover 1, the discharging structure 3 that the lower inside of enclosing cover 1 is provided with is corresponding with the fuel filler pipe mouth of pipe, can conduct electricity, discharging structure 3 has discharging gap 4 between the two to the direction projection of fuel filler pipe.In the present embodiment, discharge mechanism 3 is column convex bodys.The width of discharging gap 4 is 0.5 millimeter.Discharge mechanism 3 is connected with enclosing cover 1 one.The threaded portion 2a root of screw shell 2 is arranged with rubber seal 5.
Present embodiment in use, after the sealing of fuel filler pipe lid, form certain discharge discharging gap 4 between enclosing cover 1 and the fuel filler pipe, when the electrostatic potential of the electrostatic potential of fuel filler pipe and enclosing cover 1 was unequal, static can produce electrostatic safety release in discharging gap 4.In the time of external world's contact fuel filler pipe lid, the fuel filler pipe lid conducts electricity, and the extraneous electrostatic pressure and the electrostatic pressure of fuel filler pipe are unequal, and static is the size of electrostatic potential safe release in discharging gap 4 thereupon also.Like this, the discharging structure of fuel filler pipe lid can effectively be controlled at the electrostatic potential in the fuel tank, keep balance according to the electrostatic potential extent between fuel filler pipe and the fuel filler pipe lid, the voltage of static is accumulated to a certain degree can be according to the voltage difference safe release, this instability that has just solved the static size of fuel tank fuel filler pipe accumulation discharges the hidden danger of bringing, and makes it to have obtained actv. control.
