Regular maintenance of oil in the maintenance of a car is a routine inspection item. The conventional oil change is to buy about 4L of engine oil can and replace it by the repair shop. The oil tank is a common container for storing oil. The current oil tanks are only provided with a handle on one side of the tank. When carrying and transporting oil into the fuel tank of the car, due to the heavy weight, Handcuffs are more laborious, and it is easy to cause oil leakage due to improper operation, and waste is caused by operational errors.
In view of the deficiencies in the prior art, the oil tank manufacturer has introduced an oil tank that is convenient to carry, labor-saving, not easy to leak, and not wasted. The oil tank is made of HDPE material, the top of the tank is in the shape of a "human", the nozzle is arranged on one side of the top, the top handle is arranged on the other side of the top, and the side handle is arranged on the side of the tank.
The open end of the oil nozzle of the oil tank is provided with a trapezoidal external thread with a tooth pitch of 4 mm, the open end of the oil nozzle is provided with a grease cap, and the oil nozzle cover is provided with a trapezoidal internal thread, and the trapezoidal internal thread of the grease cap is matched with the trapezoidal external thread of the open end of the grease nozzle. A plurality of anti-slip projections are uniformly arranged on the nozzle at intervals of 45°.
It can be seen that the oil nozzle of the oil tank is vertically disposed on one side of the top of the tank body, the oil nozzle is flush with the outer surface of the tank body, and the top handle and the side handle of the top of the tank body are connected as an integral structure; the trapezoidal shape of the oil nozzle cover The trapezoidal external thread of the internal thread and the open end of the nozzle is a single head; the angle between the two waist and the bottom of the trapezoidal external thread is 55° and 78°, respectively.
Since the handles are provided on the top and sides of the oil tank, when carrying and transporting the oil into the fuel tank of the automobile, it is not because of the heavy weight, the handcuffs are relatively laborious, and the oil is leaked, thereby reducing the operation error. waste. It should also be noted that the items that cannot be shipped in the oil tank are: dangerous goods such as fuming sulfuric acid, concentrated nitric acid above 55% concentration and fuming nitric acid. Benzene, toluene, xylene, chlorobenzene, gasoline, condensate, liquid ammonia, liquid chlorine, ethylene oxide, and the like.
Under normal circumstances, the bottom mold line of the oil tank should be the thickest, the minimum wall thickness should be at the corner of the product, but the angle of the lower bottom should be thicker than the angle of the top, and the thickness of the lower part of the product should be The upper part is bigger. According to the product, the wall thickness difference or the wall thickness ratio of the symmetrical part can be used to check the uniformity of the wall thickness of the product. If the wall thickness ratio of the symmetrical part is evaluated, 1:1.5 should be the upper limit.
