Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with specific embodiments.

[0015] As a better implementation method in specific implementation: figure 1 As shown, an automobile refueling structure includes a filling pipe 1. The lower outlet end 2 of the filling pipe 1 is connected to the fuel tank inlet through a hose, and the upper inlet end of the filling pipe 1 is provided with a filling port protruding out of a circular table. Head 3; the lower part of the filling pipe 1 near the outlet end 2 is designed with a zigzag-shaped buffer part 4; wherein the filling pipe 1 is located on the upper and lower ends of the buffer part 4 is also connected with a bypass buffer Blocking pipe 5.

[0016] Among them, both ends of the bypass mitigation pipe 5 are connected to the filling pipe 1 through a three-way joint 6. This can facilitate connection installation and replacement.

[0017] Wherein, the upper end of the bypass mitigation pipe 5 has an in...

Abstract

The invention discloses a car oil filling structure. The car oil filling structure comprises a filling pipe, wherein the outlet end of the bottom of the filling end is connected with the inlet of an oil tank by virtue of a hose, the inlet end of the upper part of the filling pipe is provided with a convex circular-truncated-cone-type oil filling port mounting head, and the part, which is close to the outlet end, at the lower part of the filling pipe is provided with a zigzag buffer part. The car oil filling structure is characterized in that the top and bottom ends, positioned on the buffer part, of the filling pipe are communicated with a bypass blocking buffering pipe. The car oil filling structure is simple in structure, and is used for effectively relieving the impact of an oil check valve at the inlet of the oil tank during oil filling, and better avoiding the defect that the oil overflows from the inlet of the oil tank inlet due to the fast speed of the oil, and the car oil filling structure is more convenient, safer and more reliable in oil filling.

Description

Technical field [0001] The invention relates to an automobile accessory. In particular, it relates to a vehicle refueling structure. Background technique [0002] Automobile refueling structure is a mechanism used to refuel the fuel tank. It generally includes a filling pipe. The lower outlet end of the filling pipe is connected with the fuel tank inlet by a hose. The upper inlet end of the filling pipe is provided with a round-shaped fuel filling port protruding outside. Install the head. [0003] In some existing automobile models, the position of the automobile fuel tank is designed to be relatively lower, so that the length of the filler pipe is longer, and the height difference between the fuel filler installation head and the fuel tank inlet is large. In this way, in the refueling type, the oil rushes directly into the oil tank, which is likely to cause the impact and loss of the oil blocking valve at the inlet of the oil tank. In order to solve this problem, the applicant...
