As shown in fig. 3, the filler tube 1 is enlarged to form a filler tip 11, and a tapered transition section is formed between the filler tip 11 and the filler tube 1, wherein the taper angle α of the tapered transition section is 30 degrees in order to prevent stress concentration. The conical transition section can smoothly guide the filled fuel into the fuel filling pipe 1, so that choking during fuel filling is avoided. The filler neck 3 is welded to the port of the filler end 11 of the filler tube 1 using stainless steel wire. The lower part of the oil filler 3 is formed with an anti-overflow sleeve which can prevent the fuel from overflowing during the oil filling, and the anti-overflow sleeve extends into the oil filling end 11. The air outlet end of the breather pipe 2 is welded and communicated with the peripheral surface of the oiling end 11 by adopting a stainless steel welding wire, so that the gas exhausted during oiling can circulate through the breather pipe 2. The bracket is welded between the oil filling pipe 1 and the vent pipe 2 by adopting a stainless steel welding wire and is used for ensuring the stability of the oil filling pipe 1 and the vent pipe in the space running direction, and simultaneously, the oil filling pipe assembly can be fixed on a vehicle by utilizing the bracket. The flange 4 is welded and mounted on the outer peripheral surface of the port of the oil adding end 11 by adopting stainless steel welding wires, and the position of the oil adding port 3 on the vehicle can be fixed through the flange 4. In order to prevent the oil filler pipe assembly from being damaged due to transitional wear caused by jolt of the vehicle after being mounted on the vehicle, the utility model is characterized in that a shock-absorbing protective pad 5 made of nitrile rubber is sleeved on the outer peripheral surface of the middle part of the oil filler pipe assembly 3. The damping protection pad 5 can enable the oil filler hole 3 to be in flexible contact with the vehicle, and the flange 4 is in flexible contact with the vehicle, so that the problem that abrasion is easily caused by traditional rigid contact is avoided, and the service life of the oil filler pipe can be prolonged.
As shown in fig. 5, the flange 4 of the present utility model is formed with two mounting holes 4a for fitting with a vehicle, the two mounting holes 4a are symmetrically distributed on the flange 4, and the bottom surface of each mounting hole 4a is welded with a nut 6 of SUS304 stainless steel material which is convenient to be connected with a screw rod using a stainless steel welding wire. The nut 6 is directly welded on the flange 4, so that the screw rod and the nut can be directly utilized to fix the oil filling pipe, and the efficiency of installing the oil filling pipe on a vehicle is improved.
As shown in fig. 4, the shock absorbing protective pad 5 of the present utility model is composed of a cylindrical jacket 51 coated on the outer circumferential surface of the oil filler 3 and a flange pad 52 attached to the lower end of the jacket 51, and through holes 52a through which bolts pass are formed in the flange pad 52 at the mounting holes 4a of the corresponding flange 4. The damping protection pad 5 can pad the flange 4, and can also protect the oil filler 3 to avoid the direct contact between the oil filler 3 and the vehicle.
In the embodiment, the bottom surface of the flange pad 52 is formed with a positioning post 521 near the through hole 52a, and correspondingly, the flange 4 is formed with a positioning hole 4b near the mounting hole 4a through which the positioning post 521 passes. The positioning column 521 is matched with the positioning hole 4b, so that the vibration reduction protection pad 5 sleeved on the oil filler 3 can be prevented from rotating relative to the flange 4, and the bottom surface of the flange pad 52 can be ensured to be clung to the upper plate surface of the flange 4.
In the embodiment, as shown in fig. 3, a cone 53 is formed between the connection of the sheath 51 and the flange pad 52, and a deformation space K allowing the cone 53 to deform is formed between the cone 53 and the outer peripheral surface of the fuel filler 3.
In the embodiment, as shown in fig. 1 and 2, four brackets are welded between the oil filling pipe 1 and the breather pipe 2, and the four brackets sequentially comprise a first bracket 71, a second bracket 72, a third bracket 73 and a fourth bracket 74 from top to bottom.

The oil filling pipe assembly is made of stainless steel except the shock absorption protective pad 5, has good corrosion resistance and long service life, is a product with high corrosion resistance and shock absorption, and can meet the use requirements under various severe road conditions.
In the embodiment, as shown in fig. 3, the port of the oil filler port 3 is turned over to form an arc-shaped sealing surface 3a for sealing fit with the oil tank cover, and an oil-resistant adhesive layer for enhancing the sealing effect is sprayed on the arc-shaped sealing surface 3 a. The port of the conventional oil filler 3 is also machined to form an arc-shaped sealing surface, but the sealing performance is relatively unsatisfactory because the metal sealing surface is directly matched with the oil tank cover, and the sealing performance of the oil filler can be further enhanced by spraying a layer of oil-resistant adhesive layer on the arc-shaped sealing surface 3a of the oil filler 3.
The preferred embodiments of this utility model have been described so far that various changes or modifications may be made by one of ordinary skill in the art without departing from the scope of this utility model.
