[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 — Figure 5 The device includes an intake pipe 1, with a connecting sleeve 2 at one end and a turbocharger intake port 3 at the other end. A bellows 7 is fixedly installed at the other end of the intake pipe 1, and the interior of the bellows 7 is connected to the interior of the intake pipe 1. During use, air filtered by an air filter enters the intake pipe 1, then passes through the connecting sleeve 2 and the turbocharger intake port 3 to enter the turbocharger's boost section, and finally enters the engine to complete the engine's air intake. The bellows 7 can be appropriately extended or retracted during disassembly to facilitate the installation and removal of the connecting sleeve 2. At the same time, both ends of the connecting sleeve 2 are equipped with high-temperature resistant sealing sleeves. These sealing sleeves fit the connection between the intake pipe 1 and the turbocharger intake port 3 and can deform under strong compression, thereby ensuring the airtightness of the device.

[0023] Both the turbocharger intake port 3 and the intake pipe 1 have threads 4 installed on their outer surfaces, with the two sets of threads 4 in opposite directions. Two threaded sleeves 5 are symmetrically installed on the outer surface of the intake pipe 1 and connected to the outer surface of the threaded sleeves 4. A fixing block 8 is fixedly installed on the outer surface of the threaded sleeve 5. A bolt 9 is slidably connected to the inner wall of the fixing block 8. A nut 10 is in close contact with the outer surface of the fixing block 8, and the inner wall of the nut 10 is connected to the outer surface of the bolt 9 by threads 4. A handle 11 is snapped into the inside of the fixing block 8, and the outer surface of the handle 11 has anti-slip texture. In use, first connect the intake pipe... 1. The connecting sleeve 2 is aligned with the axis of the turbocharger intake port 3. The two threaded sleeves 5 are respectively placed in appropriate positions and tightly attached to the threads 4 on the outer surface of the turbocharger intake port 3 and the intake pipe 1. The bolt 9 is inserted into the fixing block 8 installed on the threaded sleeve 5. The nut 10 is screwed on the other end of the bolt 9 to fix the two threaded sleeves 5. Then the handle 11 is inserted. The rotation of the handle 11 drives the threaded sleeve 5 to rotate. Through the thread 4 connection between the threaded sleeve 5 and the thread 4, the intake pipe 1 and the turbocharger intake port move towards each other, and an inward clamping force is applied to the middle to complete the sealing of the device.

[0024] A limiting mechanism 6 is fixedly installed on the outer surface of the intake pipe 1. The limiting mechanism 6 includes a fixed cover 601, the outer surface of which is fixedly installed to the outer surface of the intake pipe 1. A retaining ring 602 is provided inside the fixed cover 601, the outer surface of which is fixedly installed to the outer surface of the intake pipe 1. The retaining ring 602 and the fixed sleeve are connected to each other by a spring 603. A retaining tooth 12 is fixedly installed on the outer surface of the threaded sleeve 5, and the outer surface of the retaining tooth 12 is in close contact with the outer surface of the retaining ring 602. The fixed cover 601 is fixedly installed on the outer surface of the intake pipe 1 and plays a limiting and supporting role in the limiting mechanism 6. When in use, the handle 1 is rotated. 1 drives the threaded sleeve 5 to rotate, which in turn drives the retaining tooth 12 to rotate. The retaining tooth 12 moves along the outer surface of the retaining ring 602. When the retaining tooth 12 engages with the notch on the retaining ring 602, the retaining ring 602 is tightly pressed against the retaining tooth 12 under the elastic force of the spring 603. When the retaining tooth 12 moves to the next notch, it squeezes the retaining ring 602, causing the spring 603 to contract. When it continues to move to the engagement notch, the spring 603 pops the retaining ring 602 out. The notches of the retaining tooth 12 and the retaining ring 602 are both set as triangles, so that the threaded sleeve 5 can only rotate in one direction and will not automatically spring back after stopping, thus ensuring the sealing of the device.

[0025] In use, this utility model is as follows: Threads 4 are provided on the outer surfaces of the intake pipe 1 and the turbocharger intake port 3. Two threaded sleeves 5 are tightly fitted against the threads 4 at appropriate positions. A bolt 9 is inserted into the fixing block 8 installed on the threaded sleeve 5. A nut 10 is screwed onto the other end of the bolt 9 to fix the two threaded sleeves 5. Then, a handle 11 is inserted. Rotating the handle 11 causes the threaded sleeves 5 to rotate. Through the threaded connection between the threaded sleeves 5 and the threads 4, the intake pipe 1 and the turbocharger intake port move towards each other. At the same time, the rotation of the threaded sleeves 5 causes the retaining teeth 12 to rotate. The retaining teeth 12 move along the outer surface of the retaining ring 602. When the retaining teeth 12 engage with the retaining ring 602, the retaining ring 602 rotates. When the notch on ring 602 is engaged, the ring 602 is tightly pressed against the retaining tooth 12 under the elastic force of spring 603, and the threaded sleeve 5 can only rotate in one direction. After stopping, it will not automatically spring back, thus applying an inward clamping force to the connecting sleeve 2 in the middle, effectively sealing the device and facilitating its use. Secondly, through the cooperation between bolt 9, nut 10, fixing block 8 and threaded sleeve 5, during maintenance, only the nut 10 needs to be turned to separate the two threaded sleeves 5, which facilitates the replacement of the connecting sleeve 2 inside, thereby facilitating the use of the device and further making the device more practical.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
