Description

Technical Field

[0001] The utility model relates to the technical field of engine joints, in particular to a high-strength low-pressure joint for an automobile engine. Background Technique

[0002] Engine joints are key components for connecting the inside and outside of an engine. They play an important role in transmitting fluids (such as fuel, coolant, engine oil, etc.) and signals (such as sensor data, control instructions, etc.); engine air joints are crucial components in the engine system. They are responsible for connecting the air intake system of the engine to ensure that air can flow smoothly into the engine to support the combustion process.

[0003] Regarding the above and existing related technologies, the inventor believes that there are often the following defects: In the engine intake system, the joints are important connecting components. Although most intake parts of the intake system are equipped with air filtration devices, most of these air filtration devices cannot completely block particulate matter. When the subsequent equipment lacks filtration ability, it is easy for particulate matter to enter the deep space, resulting in the problems of blocking the intake passage and being inconvenient to clean; Therefore, a high-strength low-pressure joint for an automobile engine is proposed for the above problems. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique.

[0005] The technical solution adopted by the utility model to solve its technical problems is: A high-strength low-pressure joint for an automobile engine described in the utility model includes a bent pipe, a threaded head, and a filtering device.

The filtering device includes a fixed cylinder. The upper and lower ends of the fixed cylinder are respectively fixedly connected to the bottom end of the bent pipe and the upper surface of the threaded head. A receiving groove is formed on the surface of the fixed cylinder. A plurality of fixing rings are inserted into the inner wall of the receiving groove of the fixed cylinder. The inner surface of the fixing ring is fixedly connected to a filter disc. The fixing ring and the filter disc are inserted into the inner wall of the receiving groove of the fixed cylinder, and then the threaded head and the connecting head are fixed. By setting the fixed cylinder, the receiving groove, the fixing ring, and the filter disc, the air can be filtered more carefully, reducing the possibility of particulate matter entering deeper equipment.

[0006] Preferably, a sealing ring is sleeved on the surface of the fixed cylinder. Two insertion posts are fixedly connected to the side wall of the sealing ring near the fixing ring, and anti-detachment rubber rings are provided on the surfaces of the two insertion posts. Push the sealing ring to drive the insertion posts and the fixing ring to move. The sealing ring fits the fixed cylinder. By setting the sealing ring, the sealing performance of the fixed cylinder can be increased.

[0007] Preferably, two fixing straps are fixedly connected to the side wall of the sealing ring. A clamping block is fixedly connected to the surface of the fixing cylinder near the fixing strap.

The side wall of the receiving ring is fixedly connected to the side wall of the fixing ring. The sealing strip is located directly above the receiving ring. A plug block is fixedly connected to the bottom end of the sealing strip. The plug block is inserted into the inner surface of the receiving ring. A prompting note is arranged on the inner surface of the receiving ring. Push the sealing strip to make the sealing strip drive the plug block to slide. The plug block is inserted into the inner wall of the receiving ring. By setting the receiving box, the sealing strip and the plug block, the prompting note can be fixed, so as to conveniently prompt the joint information or the filter disc usage information.

[0011] Preferably, fixing blocks are fixedly connected to both sides of the receiving ring. Moving blocks are slidably connected to the surfaces of the two fixing blocks. The upper surfaces of the two moving blocks are fixedly connected to the bottom end of the sealing strip. The moving blocks slide on the surfaces of the fixing blocks.
