Description

Technical Field

[0001] This application relates to the field of fuel tank technology, and in particular to an insulating component for the internal casing of a fuel tank. Background Technology

[0002] The insulation components of plastic fuel tanks are typically made of materials such as polyethylene (PE), polypropylene (PP), and polytetrafluoroethylene (PTFE). These materials have excellent insulation properties, effectively isolating the fuel inside the tank from the external environment and ensuring the safe operation of the fuel system.

[0003] Currently, when connecting a plastic fuel tank to a fuel pump, the connection point lacks a secondary sealing structure after installation, leading to dust infiltration due to insulation component movement over long-term use. This contaminates the internal gasoline and affects its usability. Therefore, an insulation component was designed for the internal casing of the fuel tank to address the aforementioned problems. Utility Model Content

[0004] To address this issue, this application provides an insulating component for the internal casing of a fuel tank. By adding a protective plate at the connection between the connector and the main body of the insulating component, the protective plate can shield and protect the connection, thus keeping the gasoline inside the plastic fuel tank pure.

[0005] The technical solution provided in this application for an insulating component for the internal casing of a fuel tank is as follows:

[0006] An insulating component for the internal casing of a fuel tank includes an insulating component body, an mounting plate fixedly connected to the upper end of the insulating component body, a fuel pump connecting pipe fixedly mounted on the upper part of the insulating component body, a fixing groove formed at the upper end of the insulating component body, a fixing plate snapped into the fixing groove, a protective plate fixedly connected to the upper end of the fixing plate, the protective plate being perpendicular to the fixing plate, and the protective plate being assembled into a protective ring. After the protective plate is fixed, it forms a protective ring to protect the connecting pipe.

[0007] Preferably, the fixing groove is annular, and mounting rods are fixedly connected at equal intervals on the inner and outer ring sidewalls of the fixing groove. The mounting rods are slidably connected to insert blocks on the side away from the inner wall of the fixing groove, and the insert blocks are inserted into the fixing plate.

[0008] Preferably, the fixing plate is arc-shaped, and a slot is provided on one side of the fixing plate, the slot and the plug being compatible.

[0009] Preferably, the insert block has an installation groove on the side near the mounting rod, an elastic sheet is fixedly connected in the installation groove, and the mounting rod is fixedly connected on the side of the elastic sheet away from the insert block.

[0010] Preferably, a shielding ring is inserted into the fixing groove, and a pull block is fixedly connected to the upper end of the shielding ring. The shielding ring is used to protect the insert block and the mounting rod.

[0011] Preferably, the mounting plate has threaded holes at equal intervals on its upper end, and screws are threaded into the threaded holes.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. In this utility model, by adding a protective plate at the connection between the connector and the main body of the insulating component, the protective plate can shield and protect the connection, preventing the continuous movement of the connector during long-term use from causing the gap at the connection between the connector and the main body of the insulating component to increase, thus preventing oil leakage or dust from entering, and keeping the gasoline in the plastic fuel tank pure.

[0014] 2. In this utility model, the fixing plate and the protective plate are connected by a snap-fit ​​method, which makes the installation convenient. Furthermore, multiple protective plates are assembled into a ring shape, which can effectively cover the connection between the connector and the main body of the insulating component, thus providing full protection for the connection.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses an insulating component for the internal casing of a fuel tank. (Refer to...) Figure 1-5An insulating component for the internal casing of a fuel tank includes an insulating component body 1, a mounting plate 2 fixedly connected to the upper end of the insulating component body 1, and threaded holes evenly spaced on the upper end of the mounting plate 2. Threaded screws are threaded into these holes for fixed connection between the insulating component body 1 and the fuel tank. Figure 3 As shown;

[0023] By adopting the above technical solution, a fuel pump connecting pipe is fixedly installed on the upper part of the insulating component body 1. A fixing groove 3 is opened at the upper end of the insulating component body 1, and the fixing groove 3 is circular. A fixing plate 4 is snapped into the fixing groove 3, and a protective plate 5 is fixedly connected to the upper end of the fixing plate 4. The protective plate 5 is perpendicular to the fixing plate 4, and the protective plate 5 can be assembled into a protective ring. After the protective plate 5 is fixed, it forms a protective ring to protect the connecting pipe.

[0024] By adopting the above technical solution, mounting rods 6 are fixedly connected at equal intervals on the inner and outer ring sidewalls of the fixing groove 3. The mounting rods 6 are slidably connected to the insert block 7 on the side away from the inner wall of the fixing groove 3. The insert block 7 is inserted into the fixing plate 4. The fixing plate 4 is fixed by inserting the insert block 7 into the fixing plate 4. The fixing plate 4 is fixed by inserting the insert block 7 into the fixing plate 4. This makes it easy to use the upper protection plate 5.

[0025] By adopting the above technical solution, a shielding ring 31 is inserted into the fixing groove 3, and a pull block is fixedly connected to the upper end of the shielding ring 31. The shielding ring 31 is used to protect the insert 7 and the mounting rod 6. The fixing plate 4 is arc-shaped, and a slot 41 is opened on one side of the fixing plate 4. The slot 41 is compatible with the insert 7.

[0026] By adopting the above technical solution, the insert 7 has an installation groove on the side near the mounting rod 6, and an elastic piece 8 is fixedly connected in the installation groove. The side of the elastic piece 8 away from the insert 7 is fixedly connected to the mounting rod 6. The elastic piece 8 can push the insert 7 on one side to move when it is restored after being squeezed, so that the insert 7 can be restored and enter the slot 41 of the fixing plate 4, thereby completing the fixation of the fixing plate 4.

[0027] The implementation principle of an insulating component for the internal casing of a fuel tank according to an embodiment of this application is as follows: The insulating component body 1 is installed at the connection port opened at the upper end of the plastic fuel tank, and the mounting plate 2 of the insulating component body 1 contacts the upper wall of the plastic fuel tank. The plastic fuel tank is then connected by screw threads to fix the insulating component body 1 to the plastic fuel tank. Then, the pull block is pulled to remove the shielding ring 31, so that the fixing groove is fully exposed to the outside. Then, the insert block 7 is pushed to move the insert block 7 closer to the side closer to the mounting rod 6, and the elastic piece 8 in the mounting groove is contracted. Then, the fixing plate 4 is moved to insert the fixing plate 4 into the fixing groove 3, and the fixing plate 4 is pressed tightly against the inner side wall of the fixing groove 3, so that the lower part of the protective plate 5 at the upper end of the fixing plate 4 is pressed tightly against the connector of the connecting wire to shield it, so that the connection between the insulating component body 1 and the connector is shielded.

[0028] Then loosen the plug 7, so that the plug 7 is pushed and moved by the elastic piece 8 and inserted into the slot 41, so that the plug 7 is engaged with the fixing plate 4, keeping the fixing plate 4 stable. Then install the remaining fixing plates 4 in sequence, so that the protective plate 5 assembly is connected and assembled into a ring shape, completely covering the connection between the connector and the main body 1 of the insulating component, thereby completing the protection and preventing oil leakage or dust from entering the gaps at the connection after long-term use.
