The upper portion of the connecting rod extends into the lower cover, and the upper portion thereof is sequentially sleeved with the spring and the lower cover from top to bottom. The diaphragm and the diaphragm bracket are fixedly connected to the top end of the connecting rod from top to bottom. The upper portion of the spring is fixedly connected to the diaphragm bracket and both are positioned within the cavities of the upper and lower covers. The air nozzle is rotatably connected to the top of the upper cover.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A turbocharger stable actuator includes a turbocharger 1 and an actuator body 2. The actuator body 2 consists of an actuator upper cover 3 and an actuator lower cover 4. Two mounting bolts 5 are threadedly connected to the turbocharger 1. Two connecting rods 6 are provided on the outer wall of the actuator lower cover 4. Locking bolts 7 are threadedly connected in the two connecting rods 6. One end of the two locking bolts 7 is movably connected with an insert 8. The end of the insert 8 close to the mounting bolt nut 5 is inclined. A slot 9 is provided on one end of the insert 8. The threaded sections of the two mounting bolts 5 are respectively arranged in the slots 9 at corresponding positions. An air pipe 10 is connected to the actuator upper cover 3. A ball shaft 11 is movably connected in the air pipe 10. A gas nozzle 12 is connected to the ball shaft 11. A nut 13 is threaded on the air pipe 10, and the nut 13 is sleeved on the gas nozzle 12.

[0022] Through the cooperation between the connecting rod 6, locking bolt 7, insert block 8, slot 9 and mounting bolt 5, the locking bolt 7 is screwed to make the insert block 8 move toward the mounting bolt 5 and wrap it. At the same time, the inclined surface of the insert block 8 generates pressure between the connecting rod 6 and the mounting bolt 5, thereby fixing the actuator body 2 on the turbocharger 1. Placing the connection and fixing mechanism of the actuator outside the device effectively reduces damage to the actuator lower cover 4, ensures the sealing inside the actuator body 2, avoids the problem of insufficient air pressure, and ensures the stable operation of the actuator. At the same time, the screw hole on the turbocharger 1 for screwing the mounting bolt 5 is retained. By adding a ball shaft 11 inside the air pipe 10 and connecting the air nozzle 12 with the ball shaft 11, the air nozzle 12 can be adjusted in multiple directions on the air pipe 10. The threaded connection with the air pipe 10 through the nut 13 achieves the angle locking effect after the air pipe 10 is angled, effectively avoiding the problem of bending of the air supply air pipe.

[0023] Specifically, in this embodiment, a threaded hole is provided on the connecting rod 6 to match the threaded section of the locking bolt 7, thereby ensuring the connection effect between the locking bolt 7 and the connecting rod 6 and achieving the purpose of screwing and moving the locking bolt 7.

[0024] Specifically, in this embodiment, a connecting shaft 14 is connected to one end of the locking bolt 7. The outer diameter of the connecting shaft 14 is larger than the outer diameter of the threaded section of the locking bolt 7. The connecting shaft 14 is rotatably connected to one end of the plug block 8, providing support for the locking bolt 7 to reverse and drive the plug block 8 to move back, while making the tightening of the locking bolt 7 and the movement of the plug block 8 synchronous and independent.

[0025] Specifically, in this embodiment, a guide rod 15 is connected to one end of the insert block 8, and the guide rod 15 is parallel to the locking bolt 7. The guide rod 15 is slidably connected in the connecting rod 6 to provide a horizontal movement guide for the insert block 8, thereby ensuring the fit between the slot 9 and the mounting bolt 5.

[0026] Specifically, in this embodiment, the inner wall of the top end of the trachea 10 is hemispherical, and the ball shaft 11 is movably connected inside the top end of the trachea 10 to provide support for the bottom of the ball shaft 11, thereby achieving the effect of applying pressure to the ball shaft 11 by screwing the nut 13 to fix it.

[0027] Specifically, in this embodiment, the bottom end of the nut 13 is threadedly connected to the air pipe 10, and the inner wall of the middle part is arc-shaped, which is adapted to the ball shaft 11 to prevent extrusion damage to the outer wall of the ball shaft 11.

[0028] Specifically, in this embodiment, the inner diameter of the top end of the nut 13 is larger than the outer diameter of the air nozzle 12 and smaller than the diameter of the ball shaft 11 , providing a compact support for the top of the ball shaft 11 and an effective range for the angle adjustment of the air nozzle 12 .

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
