Description

Technical Field

[0001] This utility model belongs to the field of exhaust pipe bracket technology, specifically relating to a fixing bracket for automotive aftertreatment exhaust pipes. Background Technology

[0002] With economic development, the automotive industry is also developing rapidly. The exhaust pipe is a component of a car. It has the function of purifying the exhaust gas and changing the airflow. Therefore, it is an indispensable part of a car. Since the exhaust pipe cannot be directly fixed by drilling holes, a bracket is needed to connect the exhaust pipe to the vehicle frame.

[0003] Currently, most existing automotive exhaust pipe mounting brackets on the market have relatively simple structures and limited functions. Traditional mounting brackets typically use fixed-size clamping structures, making it difficult to adapt to the installation requirements of exhaust pipes of different specifications and diameters. In practical applications, if the exhaust pipe specifications do not match the bracket, the entire bracket needs to be replaced, increasing usage costs and maintenance difficulty. Based on the above problems, this application proposes an automotive aftertreatment exhaust pipe mounting bracket to improve these issues. Utility Model Content

[0025] Please see the appendix Figures 1 to 3As shown, this utility model provides a mounting bracket for an automotive aftertreatment exhaust pipe, including an upper clamping plate 10 and a lower clamping plate 11. The lower clamping plate 11 is located at the lower end of the upper clamping plate 10. Fixing plates 12 are fixed on both sides of the lower end of the upper clamping plate 10. A spring 13 is provided at the lower end inside the fixing plate 12. Slide plates 14 are fixed inside the fixing plate 12 and at both ends of the spring 13. The two slide plates 14 are slidably connected to the fixing plate 12. A locking block 15 is fixed at the opposite end of the two slide plates 14. A connecting groove 16 is provided on both sides of the upper end of the lower clamping plate 11. A base plate 17 is fixed at the lower end of the lower clamping plate 11. Side plates 18 are fixed on both sides of the upper end of the base plate 17. The lower clamping plate 11 is located between the two side plates 18. Threaded rods 19 are rotatably connected inside the two side plates 18. A movable plate 20 is threadedly connected to the outer side of the two threaded rods 19. One side of the movable plate 20 extends into the interior of the connecting groove 16. The lower end of the locking block 15 has a first inclined surface 21, and the upper end of the interior of the moving plate 20 has a second inclined surface 22, and the first inclined surface 21 and the second inclined surface 22 are adapted to each other. A limiting plate 23 is fixed on the outer side of the fixing plate 12, and the limiting plate 23 is located at the upper end of the moving plate 20.

[0026] In this embodiment, when it is necessary to fix the automotive aftertreatment exhaust pipe, the automotive aftertreatment exhaust pipe is placed between the upper clamping plate 10 and the lower clamping plate 11. When the lower clamping plate 11 moves upward, the fixing plate 12 at the lower end of the upper clamping plate 10 is located inside the communicating groove 16. Because one side of the moving plate 20 extends into the communicating groove 16, the lower end of the locking block 15 is provided with a first inclined surface 21, and the upper end of the interior of the moving plate 20 is provided with a second inclined surface 22. The first inclined surface 21 and the second inclined surface 22 are adapted to each other. Therefore, when the fixing plate 12 moves downward, the locking block 15 is located on the first inclined surface 21. The upper end of the movable plate 20 has a second inclined surface 22, which drives the two sliding plates 14 to move closer together. The two sliding plates 14 move closer together, thereby compressing the spring 13. When the fixed plate 12 passes through the lower end of the movable plate 20, the locking block 15 is located at the lower end of the movable plate 20. Under the action of the spring 13, the two sliding plates 14 are pushed away from each other. The two sliding plates 14 drive the locking block 15 away from each other. When the locking block 15 is no longer moving, the locking block 15 and the limiting plate 23 can lock the movable plate 20, thereby satisfying the need for pressing and fixing exhaust pipes of different sizes. It should be noted that the two ends of the connecting groove 16 have through holes. When it is necessary to remove the lower clamping plate 11, the two locking blocks 15 are pushed closer together by the passage at both ends. When the two locking blocks 15 are located inside the fixed plate 12, the lower clamping plate 11 can be moved downward to separate the upper clamping plate 10 and the lower clamping plate 11.

[0027] Secondly, please refer to the following as well. Figure 3The side plate 18 has grooves 24 at both ends, and the movable plate 20 has sliders 25 fixed at both ends. The grooves 24 and sliders 25 are compatible. The bottom plate 17 has rotating rods 26 rotatably connected to both sides. The upper end of the rotating rod 26 is fixedly connected to the lower end of the threaded rod 19. The lower end of the rotating rod 26 is fixed with a knob 27. The outer side of the knob 27 has anti-slip texture.

[0028] In this embodiment, rotating the knob 27 causes the rotating rod 26 to rotate, which in turn causes the threaded rod 19 inside the side plate 18 to rotate. The threaded rod 19 then moves the movable plate 20. Since the sliders 25 at both ends of the movable plate 20 slide along the grooves 24 inside the side plate 18, the movable plate 20 moves smoothly within the connecting groove 16, providing precise guidance for its movement and preventing deviation during movement. When fixing exhaust pipes of different sizes, the fixed plate 12 is positioned differently inside the connecting groove 16. By rotating the knob 27, the position of the movable plate 20 within the side plate 18 can be changed, allowing the movable plate 20 to be positioned between the locking block 15 and the limiting plate 23, thus facilitating the locking and fixing of the movable plate 20 and the fixed plate 12.

[0029] In a preferred embodiment, please refer to Figure 2 The upper clamping plate 10 has a first ear plate 28 fixed at both ends of its outer side, and the lower clamping plate 11 has a second ear plate 29 fixed at both ends of its outer side. The second ear plate 29 is located at the upper end of the side plate 18, and the first ear plate 28 and the second ear plate 29 are connected by bolt threads.

[0030] In this embodiment, after the movable plate 20 and the fixed plate 12 are snapped together, the first ear plates 28 at both ends of the outer side of the upper clamping plate 10 are placed correspondingly to the second ear plates 29 at both ends of the outer side of the lower clamping plate 11. The connection is made more secure by bolts passing through the first ear plates 28 and the second ear plates 29, thereby enhancing the overall structural strength of the fixed bracket.

[0031] Secondly, please refer to it again. Figure 2 A connecting plate 30 is fixed to the upper end of the upper clamping plate 10, and connecting screw holes 31 are provided at the four corners of the connecting plate 30.

[0032] The upper clamping plate 10 can be connected to the car body or other fixed parts by bolts passing through the connecting screw holes 31 at the four corners of the connecting plate 30, thereby installing the entire exhaust pipe fixing bracket in place.

[0033] Secondly, please refer to the following as well. Figure 2 The upper clamping plate 10 and the lower clamping plate 11 are both fixed with heat insulation pads 32 on their adjacent sides.

[0034] In this embodiment, during operation, the upper clamping plate 10 and the lower clamping plate 11 fix the exhaust pipe through the internal structure. The heat insulation pads 32 on the surfaces close to each other are tightly attached to the exhaust pipe to form a heat insulation barrier. The heat insulation pads 32 have a certain buffering effect, which can reduce the impact of exhaust pipe vibration on the upper clamping plate 10 and the lower clamping plate 11 and extend the service life of the fixed bracket.

[0035] The working principle of this utility is as follows:

[0036] The exhaust pipe is placed between the upper clamping plate 10 and the lower clamping plate 11. The lower clamping plate 11 moves upward so that the fixing plate 12 enters the connecting groove 16. The first inclined surface 21 of the locking block 15 cooperates with the second inclined surface 22 of the moving plate 20 to compress the spring 13. When the fixing plate 12 passes through the moving plate 20, the spring 13 pushes the locking block 15 to engage the moving plate 20 with the limiting plate 23 to achieve a locking and fixing. Rotating the knob 27 drives the threaded rod 19 to rotate via the rotating rod 26, so that the moving plate 20 moves under the guidance of the slider 25 and the sliding groove 24 to adjust its position to adapt to exhaust pipes of different sizes. Then, the first ear plate 28 and the second ear plate 29 are connected by bolts to enhance the overall strength. Finally, the bracket is fixed to the vehicle body and other components using the connecting screw hole 31 at the end of the connecting plate 30. During the installation process, the heat insulation pad 32 between the upper clamping plate 10 and the lower clamping plate 11 not only blocks the heat of the exhaust pipe but also buffers vibration, protecting the bracket and the exhaust pipe.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
