Abstract
The invention discloses an oil discharging system of a plastic oil tank. The oil discharging system comprises a plastic oil tank, a plastic step, a metal nut base, a metal nut and an O-shaped sealing ring, wherein the metal nut base is embedded in the center of the plastic step by adopting an injection molding process, the metal nut can be screwed in or screwed out the metal nut base, the plastic step is assembled on the plastic oil tank to form an integral structure, and is set to be of a two-stage lug boss form gradually increased from outside to the center, and the O-shaped sealing ring is located between the head of the metal nut and two layers of lug bosses of the plastic step. A conventional metal device is remained for opening or closing the oil discharging system, and the oil discharging system has wear-resistant effect in an opening or closing process. According to the oil discharging system, the problem of penetration caused by directly assembling a metal opening or closing system on the plastic oil tank is solved. Meanwhile, the O-shaped sealing ring is additionally arranged between the two layers of lug bosses and the metal nut, and thus if the O-shaped sealing ring is pressed on the metal nut base, oil leakage is caused; by adopting the design, the oil penetration can be avoided.
Description
Technical field
The present invention relates to the technical field of automobile zero device manufacturing industry, be specifically related to the defuelling system of plastic fuel tank.
Background technology
In automobile manufacture industry, need to use fuel tank to carry out splendid attire to diesel oil and gasoline, but in the splendid attire process to bavin Water Oil Or Gas, owing to can containing more water and impurity in diesel oil or some inferior patrols, need to use the defuelling system of fuel tank that these water and impurity are discharged.
Tradition, adopts metallic oil tank, and defuelling system is the combination of metal nuts seat and metal nuts, and this kind of defuelling system is easy to be welded in metallic oil tank.But, because plastic fuel tank has a lot of outstanding features, for example entirety has reduced the quality of fuel tank and can prevent that fuel tank from getting rusty, simultaneously, the time-to-market of plastic fuel tank is short, and the life-span is long, can effectively prevent oil infiltration and in the time of fuel tank high temperature, also can prevent fuel tank explosion, there is better security and stability, thereby make plastic fuel tank on market, replace gradually metallic oil tank to become main flow.Just there is a problem in this, traditional defuelling system can not directly be welded on plastic fuel tank, the phenomenon that welding also there will be gasoline or diesel oil to infiltrate by soldered reluctantly, therefore, need to adopt a kind of defuelling system of novel type or adopt a kind of new mode that defuelling system is arranged on fuel tank.
Therefore, the problems referred to above are the problems that should pay attention to and solve in the design and use process of the defuelling system to plastic fuel tank.
Summary of the invention
For the problem of above-mentioned existence, the invention provides the defuelling system of plastic fuel tank.
Technical solution of the present invention is: the defuelling system of plastic fuel tank, comprise plastic fuel tank, plastics step, metal nuts seat, metal nuts and O RunddichtringO, described metal nuts seat adopts Shooting Technique to be embedded in the center of described plastics step, described metal nuts can screw in and screw out in described metal nuts seat, described plastics step is assemblied on described plastic fuel tank into a single integrated structure, described plastics step is set to the secondary boss form being increased progressively gradually by export-oriented center, described O RunddichtringO is between the nut head of described metal nuts and two layers of boss of described plastics step.
Further improvement of the present invention is: described O RunddichtringO adopts resistant to corrosion quality of rubber materials.
Further improvement of the present invention is: described metal nuts seat and described metal nuts are without burr, and are coated with Zinc material layer on its surface.
The defuelling system of plastic fuel tank of the present invention, is embedded in metal nuts seat in plastics step by Shooting Technique, and plastics step is assemblied in and on plastic fuel tank, is formed integrative-structure by techniques such as welding.In the time that this defuelling system is sealed, O RunddichtringO is placed on two layers of boss of plastics step, then metal nuts is screwed in metal nuts seat, O RunddichtringO is placed between two layers of boss and the nut head of metal nuts.Screw-in by metal nuts is carried out the switching to defuelling system with back-out.
The invention has the beneficial effects as follows: be designed with the defuelling system that this meets plastic fuel tank, the switching of defuelling system retains traditional metal device, can be more wear-resistant in the process of closing.Design of the present invention has solved the assembly problem of metal device on plastic fuel tank simultaneously.Adopt metal nuts seat to be embedded in plastics step by Shooting Technique, the operation that plastics step assembles with plastic fuel tank again, has avoided metal open and close system to be directly contained in the problem that can cause infiltration on plastic fuel tank.The most outstanding feature of this design is under metal nuts, to have additional an O RunddichtringO, and this O RunddichtringO is not arranged between metal nuts seat and metal nuts, and be arranged between two layers of boss and metal nuts, if cause for this reason O RunddichtringO is pressed on metal nuts seat, can cause the phenomenon of leakage of oil, and adopt this design, just can not cause oily infiltration.
