Abstract
The utility model relates to automatic cover of an oil tank. The utility model comprises an outer sleeve, an oil seepage part, a spring, and a cover plate. The utility model is characterized in that the outer sleeve is fixed on the oil tank, and the lower end of the outer sleeve is provided with a limiting lug boss; the oil seepage part is inserted in the outer sleeve, and the spring is arranged between the limiting lug boss and the upper circle of the oil seepage part; the lateral surface of the lower circle of the oil seepage part is provided with oil seepage holes, and the lower part of the lower circle of the oil seepage part is fixedly provided with the cover plate; the outer end of the limiting lug boss of the outer sleeve is provided with a sealing ring. The utility model has the function of theft prevention by means of an oil inlet mode on the lateral surface and has the function of the prevention of oil seepage by means of the isolation of the oil tank and the outside through the cover plate, and in addition, the utility model can prevent oil from being stolen and the oil seepage without being locked. The utility model has the advantages of simple structure, low cost, and safe operation.
Description
The utility model belongs to a kind of fuel lid, is a kind of automatic fuel lid for the self-propelled vehicle use specifically.
To lock mainly be guard against theft oil and leakage of oil to the tradition fuel tank, and the driver refuels to self-propelled vehicle and will take ignition key remove to open fuel lid earlier could to refuel now, so not only wasted time but also bother.Existing fuel tank cap lock gets very tight, and is very tight on the surface, do not solve the problem of key hole seepage and volatilization in fact.The disclosed patent of Patent Office of the People's Republic of China " start-stop system of the fuel lid " (patent No.: 97250515), have complex structure, the defective that manufacturing cost is high though solved the problems referred to above.
The purpose of this utility model provides a kind of tank cap lock that do not need, can guard against theft oil, and anti-leakage of oil, automatic fuel lid simple in structure again, easy to use is to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of overcoat, oil leakage, spring and cover plate, be characterized in that there is a positive stop lug boss overcoat lower end, oil leakage is a pair of cylinder, circle external diameter is less than outer casing internal diameter on it, round down external diameter is less than the positive stop lug boss internal diameter, oil leakage places in the overcoat, be mounted with spring between circle and the positive stop lug boss on the oil leakage, oil leakage has a plurality of oil leaking holes in the circle side down, cover plate is fixed on the bottom of circle under the oil leakage, and its external diameter is identical with the overcoat external diameter, is provided with seal ring in the outer end of overcoat positive stop lug boss; The outside face of overcoat has the screw thread that cooperates with fuel tank; Be provided with an oil gun position-limited lever in the circle on the oil leakage; The outside face of oil leakage is provided with the groove that vertically loses heart; The inside face of circle is an inclined-plane that matches with outer nozzle rifle head on the oil leakage.
The utility model adopts side oil-feed mode and cover plate, can prevent stolen and leakage of oil so solved just need not lock.The utility model is made up of six basic elements of character, has saved complicated locking device and labyrinth thereof, produces extremely simple, extremely low, easy to operate, the safety of cost.
Accompanying drawing is the utility model structural representation.
Among the figure: circle, the following circle of 22-oil leakage, 23-oil leakage oil leaking hole, the disappointing groove of 24-oil leakage, 3-spring, 4-cover plate, 5-seal ring, 6-oil gun position-limited lever on 1-overcoat, 11-overcoat positive stop lug boss, 12-sleeve thread, 2-oil leakage, the 21-oil leakage.
Further specify the utility model below in conjunction with accompanying drawing.
The utility model is when initial state, because the effect of spring 3, cover plate 4 is close to the bottom and the seal ring 5 of overcoat 1, and fuel tank is separated by cover plate 4 with extraneous, not only prevents stolen but also prevent leakage of oil.When needing to refuel, nozzle is inserted going up in the circle 21 of oil leakage 2, and afterburning in fuel tank, pressuring spring 3 makes cover plate 4 break away from overcoat 1, begin this moment to refuel, the quilt oiling flows in the fuel tanks by the oil leaking hole 23 of oil leakage 2 sides, and extraction nozzle after oiling finishes is because the recovery of spring 3, make the utility model revert to initial condition, finish refueling process.Oil gun position-limited lever 6 of the present utility model is used to limit the degree of depth that nozzle inserts oil leakage 2, and the disappointing groove 24 of oil leakage is used at refueling process the discharge of air in the fuel tank.
The utility model can be held the installation cover of dust on the coat for dustproof.
