Referring to fig. 1-2, an automobile fuel tank capable of preventing overflow leakage damage comprises an inner shell 2 and an outer shell 1, wherein the inner shell 2 is arranged in the outer shell 1, a mounting plate 4 is arranged above the outer shell 1 and the inner shell 2, an outer second opening 7 is arranged on the upper side of one end of the outer shell 1, an outer first opening 13 is arranged on the upper side of the other end of the outer shell 1, the outer second opening 7 is fixedly inserted in the mounting plate 4, a telescopic bag 6 is arranged above the mounting plate 4 opposite to the outer second opening 7, a one-way movable plate 9 is arranged in the outer second opening 7, the telescopic bag 6 is communicated with the inner shell 2, a connecting sleeve 5 is arranged at the position of the mounting plate 4 opposite to the outer first opening 13, the connecting sleeve 5 is clamped with the outer first opening 13, the connecting sleeve 5 is also communicated with the inner shell 2, a guide pipe 3 is clamped on the inner wall of the connecting;

wherein, outer connecting groove 11 and inner connecting groove 12 have been seted up to the one end that connecting sleeve 5 is close to shell body 1, and interior casing 2 is provided with interior first opening 14 with the relative position of connecting sleeve 5, and interior first opening 14 joint is in inner connecting groove 12, and outer first opening 13 joint is in outer connecting groove 11. An outer connecting groove 11 and an inner connecting groove 12 are formed in the connecting sleeve 5, the outer shell 1 is sleeved on the outer side of the inner shell 2, and in order to ensure that the connecting sleeve 5 is well connected with the outer shell 1 and the inner shell 2, the outer connecting groove 11 and the inner connecting groove 12 are arranged for respectively installing an outer first opening 13 and an inner first opening 14, so that good sealing performance is ensured;

wherein, the snap ring 10 is installed to the symmetry on outer second opening 7's the inner wall, form the draw-in groove between snap ring 10 and outer second opening 7's the inner wall, be provided with the interior second opening 8 that corresponds with outer second opening 7 on the interior casing 2, interior 8 joints of second opening are in one of them draw-in groove, flexible bag 6 is provided with the connector, the connector joint is in another draw-in groove, use the draw-in groove structure of snap ring 10 with outer 7 inner wall formation of second opening, a connector for interior second opening 8 of casing 2 and flexible bag 6 are enclosed in the joint, thereby realize the linkage between flexible bag 6 and the interior casing 2, be provided with sealed piece on connecting sleeve 5's the inner wall, the sealed piece of pipe 3 joint is at sealed piece, install sealed piece in connecting sleeve 5, be used for avoiding the interior fuel refluence of interior casing 2.

In the invention, when a user uses the device, fuel is conveyed into the inner shell 2 through the conduit 3, wherein the material of the inner shell 2 is soft PVC material, and gasoline fuel has no corrosivity to the inner shell, so the device can be used for filling fuel, when the outer side of the outer shell 1 is impacted, if the outer surface of the outer shell 1 is impacted to deform but not break, if the inner part is full of fuel, the outer shell 1 is impacted to deform, the inner space is reduced, the fuel can still cause the outer shell 1 to break under the pressure action of liquid, and the inner part has the danger of backflow during extrusion, so a sealing block is arranged inside a connecting sleeve 5 connected with an engine and the like, thereby effectively avoiding the backflow of the fuel, because the material of the inner shell 2 is soft, the fuel can deform along with the impact, when the inner fuel is full of liquid, because one-way fly leaf 9 is one-way open, then in fuel can enter into the bellows 6 through one-way fly leaf 9, the bellows 6 is scalable expanded structure, occupation space and quality when not using, the fuel that is extruded because the space is not enough after the striking can be collected by the bellows 6, wherein the bellows 6 also is corrosion-resistant PVC material, even then the shell body 1 is strikeed and takes place the deformation, inside fuel also can be by effectual collection, can avoid its overflow to leak out, avoid causing the emergence of conflagration because the fuel overflow leaks.

The outer shell 1 is made of rigid metal, and is easily broken directly due to excessive force in the process of being impacted, if the outer shell 1 is impacted by a sharp object, the outer shell 1 is more likely to break directly, but because the inner wall of the outer shell 1 has the soft inner shell 2, the rigidity is insufficient, but the flexibility is good, the corresponding deformation can be generated along with the impact, so that the damage of the structure of the inner shell 2 caused by direct hard impact is effectively avoided, and the inner shell 2 is made of soft PVC material and is hard to recover the deformation in the case of being damaged in the face of a sharp impact object, compared with the rigid metal material, once the inner shell is damaged, even if the inner shell 2 cracks, the inner shell 2 has elasticity and can recover the deformation when the external force is lost, so that the shape of the inner shell 2 can be recovered well after being deformed, the crack part can be temporarily closed due to the elastic force of the inner part, the gasoline is liquid with high viscosity, once the inner shell 2 recovers the shape, the crack part is closed, the gasoline fuel in the inner part is still difficult to flow out, the fuel is still difficult to flow out in a damaged state, the fuel is not missed, and the fire problem caused by gasoline leakage is greatly reduced.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
