[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5A fuel pump mounting device for automobiles includes a fuel tank 1, a mounting mechanism, a fixing component, and a filter mechanism. The mounting mechanism includes a pump body 2, a fixing bracket 3, a first spring 4, a threaded sleeve 5, and a sealing element 6. The pump body 2 is mounted on the fuel tank 1 and connected to it. The fixing bracket 3 is mounted on the fuel tank 1 and slidably connected to it. The first spring 4 is fixedly mounted on the fuel tank 1, and its other end is fixedly connected to the fixing bracket 3. The threaded sleeve 5 is mounted on the fuel tank 1 and connected to the pump body 2. The sealing element 6 is mounted on the threaded sleeve 5 and rotatably connected to it. The fixing component includes a second spring 7, a reset bracket 8, a fuel supply pipe 9, and a fixing bolt 10. The second spring 7 is fixedly mounted on the pump body 2, and its other end is fixedly connected to the reset bracket 8. The reset bracket 8 is mounted on the pump body 2 and slidably connected to it. The fuel supply pipe 9 is mounted on the pump body 2 and connected to it. The fixing bolt 10 is mounted on the fuel supply pipe 9 and connected to the threaded sleeve 5.

[0031] In this embodiment, the installation mechanism includes a pump body 2, a fixing frame 3, a first spring 4, a threaded sleeve 5, and a sealing element 6. In use, the pump body 2 can be installed onto the oil tank 1 first, and then the pump body 2 can be installed into the placement frame 18 in the oil tank 1. The limiting block 20 on the pump body 2 is connected to the limiting groove on the placement frame 18, and the bottom end of the pump body 2 is in contact with the fixing frame 3. The fixing frame 3 is compressed by the force, thereby compressing the first spring 4 installed in the placement groove 19. At this time, the threaded sleeve 5 can be installed. During the connection and installation of the threaded sleeve 5 with the oil tank 1, the threaded sleeve 5 also compresses the pump body 2. At the same time, the sealing gasket 24 on the sealing element 6 installed on the threaded sleeve 5 contacts the pump body 2 and rotates in the threaded sleeve 5. As the threaded sleeve 5 and the oil tank 1 are connected, the sealing gasket 24 can be compressed, thereby sealing the connection between the pump body 2 and the threaded sleeve 5.

[0032] In this embodiment, the fixing assembly includes a second spring 7, a reset frame 8, an oil supply pipe 9, and a fixing bolt 10. In use, the oil supply pipe 9 can be installed onto the connecting pipe 23 of the pump body 2. At this time, the first locking block 22 on the oil supply pipe 9 is installed into the mating groove 26 of the connecting pipe 23, and the oil supply pipe 9 contacts the reset frame 8. At this time, the reset frame 8 is compressed under the contact of the oil supply pipe 9, thereby compressing the second spring 7. Rotating the oil supply pipe 9, the second locking block 25 on the oil supply pipe 9 and the connecting block 27 on the threaded sleeve 5 are aligned. At this time, the fixing bolt 10 can be installed on the second locking block 25, thereby fixing the oil supply pipe 9 onto the connecting pipe 23, thus completing the fixing of the oil supply pipe 9.

[0033] In this embodiment, the filtration mechanism includes a mounting frame 11, a filter screen 12, a first filter element 13, and a second filter element 14. In use, the oil tank 1 is filled with oil through the oil inlet 15. Then, under the operation of the pump body 2, the gasoline in the tank is drawn into the main pipe 16 and the secondary pipe 17 at the bottom of the pump body 2. The filter screen 12 in the mounting frame 11 at the bottom of the main pipe 16 filters out coarse impurities. After passing through the filter screen 12, the first filter element 13 filters out fine impurities in the gasoline. The second filter element 14 in the secondary pipe 17 also filters out fine impurities in the gasoline at the same time. Thus, gasoline is sprayed from the connecting pipe 23 of the pump body 2 to the oil delivery pipe 9.

[0034] Example 2:

[0035] In summary, during use, the pump body 2 is first installed onto the oil tank 1, and then installed into the mounting bracket 18 within the oil tank 1. The limiting block 20 on the pump body 2 is connected to the limiting groove on the mounting bracket 18, while the bottom of the pump body 2 contacts the fixing bracket 3. The pressure exerted by the fixing bracket 3 compresses the first spring 4 installed in the mounting groove 19. At this point, the threaded sleeve 5 can be installed. During the connection and installation process between the threaded sleeve 5 and the oil tank 1, the threaded sleeve 5 also compresses the pump body 2. Simultaneously, the sealing gasket 24 on the sealing element 6 installed on the threaded sleeve 5 contacts the pump body 2 and rotates within the threaded sleeve 5. As the threaded sleeve 5 connects to the oil tank 1, the sealing gasket 24 can be compressed, thereby sealing the connection between the pump body 2 and the threaded sleeve 5. After the pump body 2 is fixedly installed, the oil delivery pipe 9 can be installed onto the connecting pipe 23 of the pump body 2. At this point, the first locking block 22 on the oil delivery pipe 9 is installed into the mating groove 26 of the connecting pipe 23. When the oil pipe 9 contacts the reset frame 8, the reset frame 8 is compressed by the contact of the oil pipe 9, which compresses the second spring 7. Rotating the oil pipe 9, the second locking block 25 on the oil pipe 9 and the connecting block 27 on the threaded sleeve 5 are aligned. At this time, the fixing bolt 10 can be installed on the second locking block 25 to fix the oil pipe 9 to the connecting pipe 23, thus completing the fixation of the oil pipe 9. Before pumping oil, the oil tank 1 is filled with oil through the oil inlet 15. Then, under the operation of the pump body 2, the gasoline in the oil tank is drawn into the main pipe 16 and the auxiliary pipe 17 at the bottom of the pump body 2. The filter screen 12 in the mounting bracket 11 at the bottom of the main pipe 16 filters out coarse impurities. After passing through the filter screen 12, the fine impurities in the gasoline are filtered out by the first filter element 13. The second filter element 14 in the auxiliary pipe 17 also filters out the fine impurities in the gasoline at the same time. Thus, gasoline is sprayed from the connecting pipe 23 to the oil pipe 9 of the pump body 2.

For all the fixed connections mentioned above, welding is preferred.
