Abstract

The utility model discloses an anti-adsorption foot pad for a base of a fuel pump. The anti-adsorption foot pad comprises an insertion column and a base pad, wherein one end of the insertion column is fixedly connected with a side face of the base pad; and a bulge is arranged on the other side face of the base pad. When the foot pad is used, the insertion column of the anti-adsorption foot pad is inserted into an insertion hole of a bottom face of the base of the fuel pump, the fuel pump is then placed on an oil tank, one side face on which the bulge is arranged is contacted with the oil tank, and a contact area of the foot pad for the base of the fuel pump and the oil tank is reduced, so that the adsorption function of the foot pad for the base of the fuel pump and the oil tank is greatly reduced, and the fuel pump can be disassembled from the oil tank easily during maintenance. The labor hour is saved, and the working efficiency is improved.

Description

A fuel pump base anti-adsorption pad

technical field

The utility model relates to a part of a fuel pump, in particular to an anti-adsorption pad for a fuel pump base. the

Background technique

In order to prevent the base of the fuel pump from slipping relative to the fuel tank, non-slip feet are installed on the base of the fuel pump. Generally, the bottom plane of the feet is a smooth surface. There is gasoline between the fuel tank, so that the adsorption force between the bottom plane of the pad and the fuel tank is very strong. When servicing the fuel pump, it can be difficult to remove the fuel pump from the fuel tank. Chinese Patent Authorization Announcement Number: CN201129249U, Authorized Announcement Date: 2008.10.08, discloses a vehicle fuel pump with good use effect, which includes a fuel tank, a fuel delivery pipe, a pump core with an oil outlet, a bracket, and a one-way check valve, base. When servicing the fuel pump, it can be difficult to remove the fuel pump from the fuel tank.

Utility model content

The problem to be solved by the utility model is that the fuel pump in the prior art is difficult to disassemble from the fuel tank. The utility model provides a fuel pump base anti-adsorption pad, which can easily disassemble the fuel pump from the fuel tank.

The purpose of this utility model is achieved through the following technical solutions. An anti-adsorption pad for a fuel pump base, comprising a post and a bottom pad, one end of the post is fixedly connected to one side of the bottom pad, and several protrusions are provided on the other side of the bottom pad. When in use, insert the post of the anti-adsorption pad into the jack on the bottom surface of the fuel pump base, and then place the fuel pump on the fuel tank. Since one side with several protrusions is in contact with the fuel tank, the fuel pump base pad is in contact with the fuel tank. The contact area of the fuel tank is reduced, which greatly reduces the adsorption effect between the feet of the fuel pump base and the fuel tank, so the fuel pump can be easily disassembled from the fuel tank for maintenance. Save hours and improve work efficiency.

Preferably, the bottom pad is circular, and the protrusions are three rings arranged on the bottom pad. The structure is simple, the manufacture is convenient, and the anti-slip effect is strong.

Preferably, a groove (4) is provided at the central line position of the three protrusions on the bottom pad, and the groove runs through from one edge of the bottom pad to the other edge of the bottom pad. It can reduce the adsorption effect between the feet and the fuel tank, and is easy to disassemble.

Preferably, a through hole is provided in the center of the bottom pad, and the through hole passes through the bottom pad and the post. It can further reduce the adsorption effect between the feet and the fuel tank, and it is easy to disassemble.

Preferably, the post is cylindrical, and the end of the post is hemispherical or conical. It is easy to operate when inserting the post of the anti-adsorption pad into the socket on the bottom surface of the fuel pump base. the

The main beneficial effect of the utility model is that the adsorption effect between the foot of the fuel pump base and the fuel tank is reduced, and the fuel pump can be easily disassembled from the fuel tank during maintenance. Save hours and improve work efficiency. the

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

As shown in Figure 1, an anti-adsorption pad for a fuel pump base includes a post 1 and a bottom pad 2. The post is cylindrical, the bottom pad is circular, and one end of the post is hemispherical or conical. The other end of the bottom pad is fixedly connected to one side of the bottom pad, and the other side of the bottom pad, that is, the bottom surface is provided with some protrusions, and the several protrusions are three rings 3 arranged on the bottom surface of the bottom pad, and the bottom surface of the bottom pad A groove 4 is formed at the center line of the upper three annular protrusions, and the groove runs through from one edge of the bottom pad to the other edge of the bottom pad. The center of the bottom pad is provided with a through hole 5, and the through hole runs through the bottom pad and the post. When in use, insert the post of the anti-adsorption pad into the socket on the bottom surface of the fuel pump base, and then place the fuel pump on the fuel tank. Since the raised bottom surface is in contact with the fuel tank, the fuel pump base pad is in contact with the fuel tank. The contact area is reduced, which greatly reduces the adsorption effect between the feet of the fuel pump base and the fuel tank, and the fuel pump can be easily disassembled from the fuel tank during maintenance. Save hours and improve work efficiency.

The above descriptions are preferred specific implementation modes of the present utility model, and are not intended to limit the implementation scope of the present utility model. The utility model can also have other embodiments, as long as it does not deviate from the spirit of the utility model, no matter what kind of transformation in form all falls within the protection scope of the utility model.
