Abstract
The utility model relates to a leak-proof oil tank cover, which includes an oil tank inner cover (2) and an oil tank outer cover (1). The leak-proof oil tank cover is characterized in that an adsorption layer and a blockage piece are further arranged between the oil tank inner cover (2) and the oil tank outer cover (1), the blockage piece is matched and connected with the oil tank inner cover (2), and the adsorption layer is arranged between the blockage piece and the oil tank inner cover (2). Through additionally mounting a foamed plastic layer and other parts in the oil tank cover, the utility model endows the oil tank cover with the leak-proof function; and the oil tank cover has the advantages of simple structure, and better manufacturability and economy.
Description
Technical field
The utility model relates to the structure of Fuel Tank inlet cover, relates in particular to a kind of antiseep fuel lid.
Background technology
Fuel lid in the existing at present design, its structure includes fuel tank inner cap and fuel tank enclosing cover, wherein fuel tank inner cap and fuel tank enclosing cover cooperatively interact, for fuel lid and fuel tank are closely cooperated, cover in its fuel tank and also be provided with seal ring and backup ring, simultaneously unobstructed in order to guarantee the gas in the fuel tank in use, fuel tank inner cap bottom offers air extractor vent, and realizes ventilation by the slit that cooperates between fuel tank inner cap and the fuel tank enclosing cover.
Fuel lid in the above-mentioned design in use because the vibration of machine is bigger, can exist the fuel in the fuel tank to leak into outside the fuel tank by the air extractor vent that covers in the fuel tank, thus problems such as energy dissipation that causes and environmental pollution.For example, because machine vibration is bigger, just there is above-mentioned gasoline leakage problems in earth rammer when operation.
The utility model content
The purpose of this utility model is to provide a kind of antiseep fuel lid.
The purpose of this utility model is achieved in that a kind of antiseep fuel lid, and it comprises fuel tank inner cap, fuel tank enclosing cover, it is characterized in that: it also includes adsorbed layer, barriers between fuel tank inner cap and fuel tank enclosing cover; Described barriers and fuel tank inner cap are connected, and adsorbed layer are set between its two.
Also be provided with filter layer between above-mentioned adsorbed layer and the fuel tank inner cap, filter layer also can play the effect of certain prevention fuel leak.
For preventing owing to the excessive situation that causes barriers to be shaken falling of vibration occurs, also be provided with spring between above-mentioned barriers and the fuel tank enclosing cover, spring one end is arranged on the air extractor vent boss of barriers, the other end and fuel tank enclosing cover are close to, spring plays good cushioning effect, can be more fixing barriers.
Also be provided with seal ring on the above-mentioned barriers, seal ring can make barriers and fuel tank inner cap closely cooperate more.
Above-mentioned barriers is a pressing plate; Above-mentioned filter layer and adsorbed layer can be foam layers, and such being provided with is beneficial to simplified structure.
The utility model is by setting up parts such as foam layer has been installed in fuel lid, make the fuel lid in the utility model have the function of the fuel leak of preventing, and this fuel lid is simple in structure, manufacturability and better economy.Wherein, the effect that stops the outside seepage of fuel had both been played in structure settings such as filter layer, had also avoided the interior air of fuel tank directly to contact with atmosphere, had certain adsorption power simultaneously again; When machine was not worked, the fuel such as gasoline that are adsorbed on the foam layer of adsorbed layer were got back to again in the fuel tank under the effect of gravity, thereby had reduced the possibility of the outside seepage of fuel; The pressing plate that is provided with seal ring has played the effect of ventilation and antiseep; Spring can prevent owing to the excessive pressing plate that causes of vibration is shaken.Fuel lid in the utility model had both stoped the seepage of fuel such as gasoline, had played the effect of ventilation again, had very high practical value.
