Carbon fiber is a high-strength, lightweight material with good heat resistance, corrosion resistance and fatigue resistance. Carbon fiber exhaust pipe can replace traditional metal exhaust pipes, with the advantages of light weight, high strength and good durability. Carbon fiber exhaust pipe plays an important role in improving automobile performance, reducing fuel consumption and reducing environmental pollution.

[0003] In the prior art, for example, a carbon fiber exhaust treatment pipe provided by Chinese patent announcement number CN213627751U has a limit rod and a pipe body that can rotate relative to each other to adjust the use length of the long rod. The long rod includes a round rod, and a connecting groove is provided on the right end face of the round rod. The inner surface of the connecting groove is movably connected with a bending rod through a thread. The length is adjusted by the thread. When in use, the limit rod is replaced or the length is adjusted to meet the use requirements, and then the intake pipe is fixedly connected to the vehicle exhaust pipe. However, the following problems still exist in the above operation process:

[0004] The tube body is only fixed to the car body by threads. When the following vehicle is driving, the vehicle bumps and easily causes relative rotation between the limit rod and the tube body. Long-term vehicle shaking and bumping will cause fatigue damage to the connection point. Frequent vibrations will cause the connection point to loosen, the threads to wear or the bending rod to deform, thus affecting the reliability of the connection. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By providing a mounting rod and a connecting end, the connecting end is threadedly fixed to the tube body, so that the length of the mounting rod can be adjusted for easy installation; by rotating the outer ring, the outer ring squeezes the clamping block through the waist-shaped hole, causing the clamping block to move closer to or away from the mounting rod, so as to achieve the effect of clamping or unlocking the outer wall of the mounting rod, thereby effectively preventing the mounting rod and the vehicle's limiting structure from rotating after installation, reducing the loosening of the connection point, thread wear or deformation of the bent rod.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, a carbon fiber exhaust gas treatment pipe comprises a pipe body 1, an air inlet pipe 2 and an air outlet pipe 3 are fixedly installed on both sides of the pipe body 1, a limiting member 4 is fixedly installed on one side of the pipe body 1, and the limiting member 4 is fixed to the limiting structure of the external vehicle to realize the installation of the exhaust gas treatment pipe, and the limiting member 4 comprises a mounting rod 12 and a connecting end 14 fixed to each other, and a mounting groove 5 is opened on one side of the pipe body 1, and the connecting end 14 is threadedly installed with the pipe body 1 through the mounting groove 5 to realize the mounting rod 12 and the pipe The body 1 is fixed, the mounting rod 12 and the connecting end 14 are integrally formed to improve the service life of the mounting rod 12 and the connecting end 14. An axial groove 13 is provided on the outside of the mounting rod 12, and an outer ring 8 is sleeved on the outside of the mounting rod 12. The outer ring 8 is rotatably connected to the tube body 1, and a waist-shaped hole 10 is provided on the outer ring 8. A clamping block 11 is provided at the waist-shaped hole 10. The clamping block 11 extends into the waist-shaped hole 10 through the shaft and is slidably connected to the waist-shaped hole 10. The clamping block 11 and the axial groove 13 are adapted to each other.

[0025] As an implementation method in this embodiment, the waist-shaped holes 10 are evenly distributed on the outer ring 8. When the outer ring 8 rotates, the outer ring 8 squeezes the block 11 through the waist-shaped holes 10, causing the block 11 to move closer to or away from the mounting rod 12, so as to achieve the effect of clamping or unlocking the outer wall of the mounting rod 12, thereby effectively preventing the mounting rod 12 from rotating after installation with the limiting structure of the vehicle, and reducing the loosening of the connection point, thread wear or deformation of the bent rod.

[0026] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, a limiting groove 6 is provided on the periphery of the mounting groove 5, and the clamping block 11 is slidably connected to the limiting groove 6. A plurality of limiting grooves 6 can be provided and are located below the number of axial grooves 13. The limiting grooves 6 are evenly distributed about the axis of the mounting groove 5, and the limiting grooves 6 limit the clamping block 11. When the outer ring 8 rotates, the outer ring 8 extends into the rod in the waist-shaped hole 10 through the waist-shaped hole 10 and the clamping block 11, thereby driving the clamping block 11 to move toward the direction of the axial groove 13 until the clamping block 11 is clamped into the axial groove 13, thereby preventing the mounting rod 12 from rotating, facilitating the installation of the mounting rod 12 and the vehicle body to prevent loosening of the connection point and wear of the thread.

[0027] As an implementation method in this embodiment, Figure 2-Figure 5 As shown, the mounting rod 12 is Z-shaped to facilitate rotation during installation. In addition to cooperating with the block 11, the multiple axial grooves 13 can also increase the surface friction of the mounting rod 12, which is convenient for the staff to grasp and rotate. An adjustment groove 7 is provided at the periphery of the mounting groove 5. The two ends of the adjustment groove 7 are arc-shaped. The outer ring 8 is located on the same side of the block 11 and is fixedly connected with a clamping column 9. The clamping column 9 is adapted to the adjustment groove 7. The clamping column 9 is clamped into the end of the adjustment groove 7. A weakening groove is provided at one end of the clamping column 9 away from the axis of the mounting groove 5 to improve the clamping column 9. The deformation effect is that when the outer ring 8 rotates, the outer ring 8 drives the clamping column 9 to move from one end of the corresponding adjusting groove 7 to the other end, so that the outer ring 8 drives the clamping block 11 from the limiting groove 6 to the axial groove 13 through the waist-shaped hole 10 to prevent the mounting rod 12 from rotating; if the outer ring 8 is rotated in the opposite direction again, the outer ring 8 drives the clamping column 9 to move again from the end of the adjusting groove 7, so that the outer ring 8 drives the clamping block 11 away from the axial groove 13 through the waist-shaped hole 10, and at this time, the mounting rod 12 can be driven to rotate to adjust the length of the mounting rod 12 for easy installation.

[0028] The working principle of the utility model is as follows: when in use, first place the tube body 1 at the required position of the vehicle, and then rotate the mounting rod 12 to make the mounting rod 12 rotate to the length required for installation. When the length adjustment of the mounting rod 12 is completed, only the outer ring 8 needs to be twisted, and the outer ring 8 drives the clamping column 9 to move from one end of the corresponding adjustment groove 7 to the other end, so that the outer ring 8 drives the clamping block 11 from the limiting groove 6 to the axial groove 13 through the waist-shaped hole 10 to prevent the mounting rod 12 from rotating, effectively preventing the mounting rod 12 and the vehicle's limiting structure from rotating after installation, and reducing the loosening of the connection point, thread wear or deformation of the bending rod.

[0029] When the mounting rod 12 needs to be replaced, the outer ring 8 is moved, and the outer ring 8 drives the block 11 away from the axial groove 13 through the waist-shaped hole 10. At this time, the block 11 no longer restricts the axial groove 13. The mounting rod 12 and the connecting end 14 can be removed from the tube body 1 by rotating the mounting rod 12, and the length of the mounting rod 12 extending out of the tube body 1 can also be adjusted to suit the installation.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
