Abstract

The utility model discloses a single-cylinder diesel engine oil tank made of plastic instead of steel, which comprises a tank body, an oil feeding port, an oil tank cover and an oil outlet pipe assembly, wherein the tank body, the oil feeding port, the oil tank cover and the oil outlet pipe assembly are made of plastic, and the oil outlet pipe assembly is connected with a base of the tank body through screws; a layer of reinforcing ring is arranged on the circumference of the lower part of a flange outside the oil feeding port; three nuts are arranged in the base in injection molding with the plastic tank body into a whole in the mode of injection molding. Compared with an existing steel single-cylinder diesel engine oil tank, the utility model has the advantages that the manufacturing technique is simple, the tank body can be formed by one-step injection molding, the cost is low, the utility model does not have the welding positions of a steel oil tank and the oil leakage is reduced. The utility model is universal with a fitting of the existing single-cylinder diesel engine oil tank; the utility model can completely replace steel single-cylinder diesel engine oil tank.

Description

Novel Fuel Tank of Single-Cylinder Diesel Engines

The utility model relates to a kind of fuel tank, and is particularly a kind of to mould the novel Fuel Tank of Single-Cylinder Diesel Engines of Dai Gang.

Present Fuel Tank of Single-Cylinder Diesel Engines is by being welded behind the cold-rolling steel-plate punch, the cost height, and complex process, in the use, because long-time vibration, the weld of fuel tank is easy to crack, and the oil spill rate after a year is about about 10%.In recent years, a lot of producers had carried out some trials to making Fuel Tank of Single-Cylinder Diesel Engines with plastic construction, and the result is very undesirable.Plastic construction fuel tank that produces and existing Fuel Tank of Single-Cylinder Diesel Engines accessory are not general, and often local strength is not enough, as oil filling port and base and oil outlet pipe assembly fixed position insufficient strength, cause the oil filling port fracture during use easily, the attaching screw of base and oil outlet assembly comes off easily, cause the damage of fuel tank, the result influences it and promotes the use of.

The purpose of this utility model provides that a kind of Dai Gang, manufacturing process are simple to mould, leakage of oil reduces and and the novel Fuel Tank of Single-Cylinder Diesel Engines of former spare part general-duty.

The purpose of this utility model is achieved in that casing, oil filling port, the fuel lid that it comprises plastics and makes, filtering net and diesel oil rough filter are arranged in the fuel tank, be access to driving engine by the oil outlet pipe assembly, in one week of oil filling port flanging bottom one deck ring stiffener is set, and be to be marked with three nuts in the base of one with the plastic box integral molded plastic, its attaching screw with the oil outlet assembly is corresponding.

Casing of the present utility model forms with plastic monoblock, and one deck ring stiffener is set in the flanging bottom of oil filling port, and the connection dimension that makes oil filling port and fuel lid meets the connection dimension of existing national standard fully, this ring stiffener can with the casing integral molded plastic, strengthened working strength like this, general with former fuel tank case lid, in at the bottom of the fuel tank, be injected with three nuts in addition, the oil outlet assembly cooperates fixing with bonded assembly screw and nut at the bottom of the case, strengthened intensity, can prevent that screw is connected with base comes off, and causes casing to damage.The utility model is compared with existing steel Fuel Tank of Single-Cylinder Diesel Engines, and manufacturing process is simple, cost is low, does not resemble the weld of steel fuel tank, has reduced leakage of oil, and general with existing Fuel Tank of Single-Cylinder Diesel Engines accessory, and it can replace the Fuel Tank of Single-Cylinder Diesel Engines of steel fully.

Below in conjunction with accompanying drawing the utility model is further described:

Accompanying drawing 1 is the utility model structural representation.

As shown in FIG., described fuel tank comprises plastic box 3, oil filling port 2, fuel lid 1, oil outlet pipe assembly 7, in the casing 3 filtering net is arranged, diesel oil rough filter 4, oil outlet pipe assembly 7 is connected with cabinet base 6 by screw, diesel oil arrives oil outlet pipe 7, of the present utility model being characterised in that: in oil filling port one week of 2 flanging bottoms one deck ring stiffener 8 is set, and makes the connection dimension of oil filling port and fuel lid 1 meet existing national standard fully by filtering net, coarse strainer 4.Be to be injected with three nuts 9 in the base of one with plastic box 3 integral molded plastics, it is corresponding with oil outlet pipe assembly 7 attaching screws 5, and wherein ring stiffener 8 can form with the casing integral molded plastic.
