Abstract
The utility model discloses a single-control fuel tank cap, which comprises a round cap body and a lining ring which is elastically clamped on the cap body and is provided with a center hole. A semi-threaded bolt, which passes through from the outer side of the lining ring to the inner side of the cap body, is arranged in the center hole of the lining ring. The threaded section of the bolt is connected with a nut. An elastic washer is sheathed on the bolt between the nut and the lining ring. The nut is screwed on the bolt and has no pressing force to the elastic washer. When the fuel tank works normally, under the gravity action of the bolt, the nut and the elastic washer, the condition that the fuel oil in the fuel tank is communicated with external atmosphere is ensured by the fuel tank cap, so that the normal fuel supply is ensured. When a machine is turned over and the fuel tank is inverted, the bolt and the lining ring in the fuel tank cap form a seal surface, so as to ensure that the fuel oil does not pass through the fuel tank cap to flow out. With the one-way control action of the fuel tank cap, when the vehicle has an accident, the condition that the fuel oil flows out due to the inversion and turnover of the fuel tank is effectively avoided.
Description
Technical field
The utility model relates to the used single controlled fuel lid of a kind of diesel oil tank.
Background technology
Fuel lid covers after on the fuel tank, fuel tank internal will communicate with ambient atmosphere, could guarantee the mobile smooth and easy of fuel oil, and the passage that fuel tank internal communicates with ambient atmosphere is generally all realized by fuel lid, during normal the use, fuel tank internal communicates with the external world by the clearance channel on the fuel lid, the supply of fuel oil proper flow, in case but fuel tank generation deflection or rollover, fuel oil in the fuel tank then is easy to leak by fuel lid, cause the waste of fuel oil, and the fuel oil that flows out is easy to generate fire accident, also contaminated environment.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of single controlled fuel lid is provided, both satisfied the regular supply of fuel tank IFO intermediate fuel oil, can prevent the fuel oil outflow when fuel tank is inverted rollover again and cause damage.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of single controlled fuel lid, comprise that circular lid and elasticity are fastened on the lining ring that has centre hole on the lid, penetrate the bolt of half thread formula in the centre hole of lining ring from lid inboard, lining ring lateral, be connected with nut on the thread segment of bolt, be with spring washer on the bolt between nut and the lining ring, nut screwing clamping does not produce thrust to spring washer after on the bolt.
Further, described lid neighboring is provided with two relative bayonet sockets, lining ring comprises the plane, outer ring and the middle evagination round platform that can be pressed on the tank filler opening, be provided with spring between the medial surface of evagination round platform and the lid medial surface, spring is pressed on the outer ring plane elasticity of lining ring on the bayonet socket of lid.
The beneficial effects of the utility model are: in the fuel tank normal operation, fuel lid relies on the action of gravity of bolt, nut and bullet pad to guarantee fuel oil and ambient atmosphere connection in the fuel tank, thereby the supply that guarantees fuel oil is normal, and when machine overturning fuel tank is inverted, bolt in the fuel lid and lining ring form sealing surface, thereby guarantee that fuel oil does not flow out by fuel lid, the utility model is by a kind of so unidirectional control action of fuel lid, prevented effectively that when vehicle meets accident fuel tank is inverted the fuel oil outflow that rollover is caused.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is the structural representation of the utility model under the fuel tank normal working.
Fig. 2 is the structural representation of the utility model under fuel tank inversion rollover state.
23. evagination round platforms, 3. bolts, 4. nuts, 5. spring washers, 6. springs in plane, 1. lid 11. bayonet sockets, 2. lining ring 21. centre holes, 22. outer ring among the figure
The specific embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The scheme drawing that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1 be the structural representation of single controlled fuel lid under the fuel tank normal working, comprise that circular lid 1 and elasticity are fastened on the lining ring 2 that has centre hole 21 on the lid 1, lid 1 neighboring is provided with two relative bayonet sockets 11, lining ring 2 comprises the plane, outer ring 22 and the middle evagination round platform 23 that can be pressed on the tank filler opening, penetrate the bolt 3 of half thread formula in the centre hole 21 of lining ring 2 from lining ring 2 lateral lids 1 inboard, be connected with nut 4 on the thread segment of bolt 3, on the bolt 3 between nut 4 and the lining ring 2, be with spring washer 5, after being tightened on the bolt 3, nut 4 spring washer 5 is not produced thrust, be provided with spring 6 between the medial surface of dome platform 23 and lid 1 medial surface outside, spring 6 with plane, outer ring 22 elastic compressions of lining ring 2 on the bayonet socket 11 of lid 1, also promptly in use, the lining ring 2 of fuel lid can be pressed on the tank filler opening.
Fuel lid is in fuel tank normal working following time, rely on the action of gravity of bolt 3, nut 4 and spring washer 5, guarantee that fuel oil and ambient atmosphere in the fuel tank can be communicated with by the gap between the centre hole 21 of bolt 3 and lining ring 2, during thereby the supply that guarantees fuel oil is normal, spring washer 5 was not produced thrust after this moment, nut 4 was tightened, guarantee not form sealing surface between spring washer 5 and the lining ring 2, the bolt 3 of half thread structure can guarantee that nut 4 and its can tighten and guarantee bolt 3 and 2 friction force minimums of lining ring.
Shown in Figure 2 is the structural representation of being inverted single controlled fuel lid under the rollover state at fuel tank, same dependence action of gravity, make the bolt 3 and evagination round platform 23 lateral surfaces of lining ring 2 form sealing surface, thereby guarantee that fuel oil does not flow out by fuel lid, both saved fuel oil, prevented also that fuel oil from flowing out the issuable disaster hidden-trouble in back.
The utility model has prevented effectively when vehicle meets accident that by a kind of so unidirectional control action of fuel lid fuel tank is inverted the fire accident that fuel oil outflows and the fuel oil outflow may bring that rollover is caused.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
