[0002] The vehicle-mounted air filter refers to the air filter installed in the vehicle engine intake system. Its main function is to filter the air entering the engine, prevent dust, sand, insects and other impurities from entering the engine, ensure that the engine inhales relatively clean air, reduce engine wear, extend engine life, and improve fuel efficiency. The air filter cartridge generally needs to be replaced regularly to maintain the air filtration effect. During the disassembly and assembly of the air filter cartridge, the air filter cartridge needs to be turned over as a whole.

[0003] In the prior art, the air filter cartridge is installed on a rotatable and adjustable bracket.

The opposite ends of the two locking components 8 are embedded in the top and bottom of the gas transmission sleeve 6. The primary threaded hole 2, the secondary threaded hole 3 and the tertiary threaded hole 4 are connected. The inner aperture of the primary threaded hole 2 is larger than the inner aperture of the secondary threaded hole 3. Through air filter cartridges 5 of different sizes, the primary threaded holes 2, the secondary threaded holes 3 and the tertiary threaded holes 4 with different aperture sizes inside the connecting sleeve 1 can be selected for threaded connection. , and fixedly installed, the inner diameter of the secondary threaded hole 3 is larger than the inner diameter of the tertiary threaded hole 4, the air delivery sleeve 6 is connected to the tertiary threaded hole 4 inside the air delivery sleeve 6, the primary threaded hole 2 is connected to the air filter cartridge 5, the mounting sleeve 7 is rotatably connected to the air delivery sleeve 6, the air filter cartridge 5 is a vehicle-mounted air filter, and the vehicle-mounted air filter refers to an air filter installed in the vehicle engine intake system. The main function is to filter the air entering the engine, prevent dust, sand, insects and other impurities from entering the engine, ensure that the engine inhales relatively clean air, reduce engine wear, extend engine life, and improve fuel efficiency. The air filter cartridge 5 generally needs to be replaced regularly to maintain the air filtering effect. During the disassembly and assembly of the air filter cartridge 5, the air filter cartridge 5 needs to be turned over as a whole, so that the air filter cartridge 5 is installed on a rotatable bracket, which is convenient for rotating and disassembling the air filter cartridge 5.

[0026] See also Figure 2-5The locking assembly 8 includes a locking nut 81, which passes through one side of the outer tube surface of the gas transmission casing 6 and one side of the inner tube surface. A locking bolt 82 passes through the top and bottom of the locking nut 81. A locking block 87 is fixedly connected to the bottom end of the locking bolt 82 and located on the outer tube surface of the gas transmission casing 6. A limiting circular plate 83 is sleeved on the top end of the locking bolt 82. A rotating block 84 is fixedly connected to the top end of the locking bolt 82 and located on the top of the limiting circular plate 83. The rotating block The top of 84 is fixedly connected with a swivel 85, and a compression spring 86 is sleeved outside the locking bolt 82 and between the bottom of the limiting circular plate 83 and the top of the locking block 87.

The compression spring 86 has a rebound tension on the limiting circular plate 83, so that when the locking bolt 82 is inserted into the slot 9 through the locking block 87 and fixes the gas transmission sleeve 6, the rebound force of the compression spring 86 can increase the pulling force between the limiting circular plate 83 and the mounting sleeve 7, thereby increasing the clamping force between the locking bolt 82 and the slot 9, so that the resonance generated by the air filter as a whole during the vehicle driving process will not cause the screw connector on the air filter bracket to loosen.

[0027] Specific implementation method: During the disassembly and assembly of the air filter cartridge 5, the air filter cartridge 5 needs to be turned over as a whole, so that the air filter cartridge 5 is installed on the rotatable bracket, which is convenient for rotating and disassembling the air filter cartridge 5. By rotating the swivel rings 85 inside the two locking assemblies 8 in the positive direction respectively, the swivel block 84 is driven to rotate, and the swivel block 84 drives the locking bolt 82 to rotate. Since the locking nut 81 is fixedly connected to the mounting sleeve 7, when the locking bolt 82 is rotated forwards and backwards on the locking nut 81, it can move up and down, so that the locking bolt 82 moves upward and drives the locking block 87 to be removed from the inside of the slot 9, and the compression spring 86 is applied with a pulling force through the limiting circular plate 83. The locking block 87 is no longer engaged with the slot 9, so that the air transmission sleeve 6 can be rotated to disassemble and assemble the air filter cartridge 5. Through air filter cartridges 5 of different sizes, the primary threaded holes 2, secondary threaded holes 3 and tertiary threaded holes 4 with different aperture sizes in the connecting sleeve 1 can be selected for threaded connection and fixed installation. The locking bolts 82 on the two locking assemblies 8 are respectively aligned with the locking blocks 87 inside the two locking components 8, and then the locking bolts 82 inside the two locking components 8 are respectively rotated in the opposite direction to move the locking blocks 87 to the inside of the slots 9 to lock and fix the gas delivery sleeve 6, so as to ensure that the air filter cartridge 5 will not rotate during the driving process of the vehicle. After the limit circular plate 83 moves and resets, the compression spring 86 has a rebound tension on the limit circular plate 83, so that the locking bolt 82 is inserted into the slot 9 through the locking block 87 and fixes the gas delivery sleeve 6. The pulling force between the limit circular plate 83 and the installation sleeve 7 can be increased by the rebound force of the compression spring 86, thereby increasing the clamping force of the locking bolt 82 and the slot 9, so that the resonance generated during the driving process of the air filter as a whole will not drive the screw connector on the air filter bracket to loosen, thereby effectively improving the installation stability of the vehicle-mounted air filter.
