Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipes, in particular to an exhaust steel pipe with a protection structure. Background Art

[0002] The exhaust steel pipe is a part of the engine exhaust system. The exhaust system mainly includes an exhaust manifold, an exhaust pipe and a muffler. Generally, a three-way catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust steel pipe generally includes a front exhaust pipe and a rear exhaust pipe, and the exhaust steel pipe is usually used in cooperation with an automobile engine.

[0003] The existing exhaust steel pipes are usually installed under the vehicle chassis. When the vehicle is running, the road conditions are complex, and the chassis is easily scratched against the ground, unable to protect the exhaust steel pipe, resulting in the exhaust steel pipe being scratched or squeezed, causing the exhaust steel pipe to crack and damage, reducing the service life of the exhaust steel pipe.

[0004] According to a high heat dissipation type automobile exhaust steel pipe provided by the publication number: CN206647156U, which includes a steel pipe body, the top of the steel pipe body is welded to the bottom of a connecting block, the top of the connecting block is fixedly connected to the bottom of a box body, a ventilation hole is opened at the top of the box body, and partition plates are fixedly installed on both sides of the ventilation hole in the inner cavity of the box body. The two partition plates divide the box body into three cavities, and the three cavities are the third cavity, the second cavity and the first cavity from left to right in sequence, and a water inlet pipe penetrates through the right side of the box body. By setting a condensation pipe and winding it on the outer surface of the steel pipe body, when the temperature of the steel pipe body rises due to the heat transfer from the automobile exhaust gas to its surface, the liquid in the condensation pipe will accelerate evaporation to absorb the heat, thereby dissipating heat and cooling the steel pipe body, achieving the effect of preventing the surface of the exhaust pipe from remaining at a high temperature, thereby increasing the safety of the automobile exhaust pipe.

[0005] According to the above-introduced exhaust steel pipe, it is impossible to protect the exhaust steel pipe, resulting in the exhaust steel pipe being scratched or squeezed, causing the exhaust steel pipe to crack and damage, reducing the service life of the exhaust steel pipe. Therefore, we need to propose an exhaust steel pipe with a protection structure. Content of the Utility Model

Detailed Embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 Figures 1-4 This utility model provides a technical solution: an exhaust steel pipe with a protection structure, which includes a pipe body 1. An air inlet 2 is provided at one end of the pipe body 1, and an exhaust port 3 is provided at the other end of the pipe body 1. A stainless steel protection net 4 is arranged on the outer surface of the pipe body 1. A protection structure 5 for protecting the exhaust steel pipe is arranged on the outer side wall of the stainless steel protection net 4. A fiberglass sleeve 6 for isolating the heat of the exhaust steel pipe is arranged on the outer surface of the protection structure 5. A heat insulation film 7 is arranged on the outer surface of the fiberglass sleeve 6. A buffer structure 8 for buffering the scraping force is arranged on the outer surface of the heat insulation film 7. A wear-resistant rubber sleeve 9 is sleeved on the outer surface of the buffer structure 8. A support structure 10 for supporting the inside of the exhaust steel pipe is arranged in the inner cavity of the pipe body 1;

[0025] When the vehicle chassis rubs against the ground, the wear-resistant rubber sleeve 9 rubs against the ground to protect the pipe body 1 through the wear-resistant rubber sleeve 9. At the same time, the force generated by the rubbing is transmitted to the buffer structure 8, and the buffer structure 8 initially buffers the rubbing force, and then is transmitted to the protection structure 5. The protection structure 5 protects the outside of the pipe body 1. The support structure 10 is provided to support the inside of the pipe body 1 to prevent the pipe body 1 from being deformed by extrusion, thereby improving the strength of the exhaust steel pipe, protecting the exhaust steel pipe, and preventing the exhaust steel pipe from cracking or being damaged when rubbed or extruded, and improving the service life of the exhaust steel pipe.

[0026] The protection structure 5 includes a fixed steel ring 51. The fixed steel ring 51 is sleeved on the outer surface of the stainless steel protection net 4. There are four groups of fixed steel rings 51, and the four groups of fixed steel rings 51 are equidistantly distributed on the outer surface of the pipe body 1. Through holes are provided on the surface of the fixed steel ring 51, and a reinforcing rib 52 is inserted and fixed in the inner cavity of the through hole of the fixed steel ring 51. Through the cooperation of the fixed steel ring 51 and the reinforcing rib 52, the outer surface of the pipe body 1 is protected, the anti-extrusion effect of the pipe body 1 is enhanced, and the outside of the pipe body 1 is reinforced.

[0027] There are six groups of reinforcing ribs 52, and the six groups of reinforcing ribs 52 are distributed around the center on the surface of the fixed steel ring 51. Through the arrangement of the reinforcing ribs 52, the stability after the connection between the fixed steel rings 51 is enhanced.

[0028] The buffer structure 8 includes a buffer ring 81. The buffer ring 81 is sleeved on the outer surface of the heat insulation film 7. The outer surface of the buffer ring 81 is bonded to the inner side wall of the wear-resistant rubber sleeve 9. Buffer strips 82 are arranged on the inner side wall of the buffer ring 81. When scraping occurs, the scraping force is transmitted to the buffer ring 81. Usually, the buffer ring 81 initially buffers the scraping force, and after buffering, it is transmitted to the buffer strips 82. The buffer strips 82 buffer the scraping force again to reduce the influence of the scraping force on the pipe body 1.

[0029] There are six groups of buffer strips 82, and the six groups of buffer strips 82 are distributed around the center of the circle on the inner side wall of the buffer ring 81. Through the setting of the buffer strips 82, the buffering effect on the rubbing force is increased.

[0030] The support structure 10 includes a support steel ring 101. The support steel ring 101 is arranged in the inner cavity of the pipe body 1. A reinforcing plate 102 is arranged in the inner cavity of the support steel ring 101. Through the setting of the support steel ring 101, the inner cavity of the pipe body 1 is supported. Through the setting of the reinforcing plate 102, the inside of the support steel ring 101 is supported.

[0031] There are three groups of reinforcing plates 102, and the positions among the three groups of reinforcing plates 102 are arranged in a triangular shape. Through the setting of the three groups of reinforcing plates 102, the stability of the support steel ring 101 during support is improved, so that the support steel ring 101 supports the inner cavity of the pipe body 1, and the pipe body 1 is prevented from deforming and cracking due to rubbing.

[0032] There are four groups of support steel rings 101, and the four groups of support steel rings 101 are equidistantly distributed on the inner side wall of the pipe body 1; through the setting of the number of the support steel rings 101, the supporting effect of the support steel rings 101 on the inner side wall of the pipe body 1 is increased, and the stability after support is improved.

[0033] During specific use: when the car chassis rubs against the ground, the wear-resistant rubber sleeve 9 rubs against the ground, and the pipe body 1 is protected through the wear-resistant rubber sleeve 9. At the same time, the force generated by the rubbing is transmitted to the buffer ring 81. Usually, the buffer ring 81 initially buffers the rubbing force, and after buffering, it is transmitted to the buffer strip 82. The buffer strip 82 buffers the rubbing force again to reduce the influence of the rubbing force on the pipe body 1. The rubbing force is transmitted to the fixed steel ring 51, and the fixed steel ring 51 supports the rubbing force. The fixed steel ring 51 and the reinforcing rib 52 cooperate to protect the outside of the pipe body 1. When the rubbing force is transmitted to the pipe body 1, the support steel ring 101 and the reinforcing plate 102 cooperate to support the inside of the pipe body 1, preventing the pipe body 1 from deforming and cracking due to the extrusion force, thereby improving the strength of the exhaust steel pipe, protecting the exhaust steel pipe, preventing the exhaust steel pipe from cracking or being damaged when rubbed or extruded, and improving the service life of the exhaust steel pipe.
