The internal thread Ⅰ41 is located on the inner wall of the first fixed sleeve column 3, and the bottom of the automobile bellows body 1 is fixedly connected with the top of the second fixed sleeve column 5. The outside of the second fixed sleeve column 5 is provided with a fixing device Ⅱ6, and the fixing device Ⅱ6 includes an internal thread Ⅱ61, an outer side of the internal thread Ⅱ61 and is located on the outer side of the second fixed sleeve column 5 An external thread II 62 is fixedly installed on the outside of the second fixed sleeve column 5, and a clamping block II 63 is fixedly installed above the external thread II 62 and located on the outside of the second fixed sleeve column 5.

The fixing device I4 and the fixing device II 6 are respectively threadedly connected with the movable sleeve column 7. The two movable sleeve columns 7 are provided with a clamping groove 8 at one end close to the automobile bellows body 1. The inside of the movable sleeve column 7 is provided with a threaded fixing device 9. Through the combination of the fixing device I4, the fixing device II 6 and the threaded fixing device 9, the connection of the automobile bellows is effectively fixed. While improving the fixation of the bellows connection, it is prevented that the automobile bellows is easily thermally deformed due to the low fixing strength of the bellows connection, which causes extreme damage to the exhaust work of the automobile. The threaded fixing device 9 includes a fixed external thread 91, a fixed sleeve 92 is fixedly sleeved on the inner side of the fixed external thread 91 and located in the middle of the movable sleeve column 7, a fixed internal thread 93 is fixedly installed on the inner wall of the fixed sleeve column 92, and the fixed external thread 91 is arranged on the outside of the movable sleeve column 7.

One end of the hydraulic adjustment cylinder 11 is fixedly connected to the inner wall of the automobile bellows body 1, and the other end of the hydraulic adjustment cylinder 11 is fixedly connected to the outside of the cooling pipe 10. The bellows is effectively cooled by the cooling pipe 10 to prevent thermal deformation of the automobile bellows.

At the same time, the adjustment of the hydraulic adjustment cylinder 11 effectively adjusts the thermal deformation of the bellows during the exhaust operation. While preventing the adverse effects of thermal deformation on the exhaust operation of the automobile from being caused by the thermal deformation of the automobile bellows, the practicality of the automobile bellows is further improved.

[0025] During operation, firstly, the internal thread I41 is threadedly connected with the fixed external thread 91, and the external thread I42 is threadedly connected with the fixed internal thread 93, so that the clamping block I43 is clamped with the clamping groove 8 at the top end of the automobile bellows body 1, and then the internal thread II61 is threadedly connected with the fixed external thread 91, and the external thread I42 is threadedly connected with the fixed internal thread 93, so that the clamping block II63 is clamped with the clamping groove 8 at the bottom end of the automobile bellows body 1, so that the upper and lower ends of the automobile bellows are fixed respectively, and the bellows is damped by the fixed damping plug 122 between the first damping disc 121 and the second damping disc 123, and the automobile bellows body 1 is further damped by the damping spring 2, and then the bellows is effectively cooled by the cooling pipe 10, and at the same time, the bellows is effectively contracted and adjusted by the telescopic adjustment action of the hydraulic adjustment cylinder 11 to prevent thermal deformation of the automobile bellows.

[0026] In summary, the bellows for preventing thermal deformation of automobiles is effectively fixed at the connection of the automobile bellows by the combination of the fixing device Ⅰ4 and the fixing device Ⅱ6 with the threaded fixing device 9. While improving the fixation of the connection of the bellows, it prevents the automobile bellows from being easily thermally deformed due to the low fixing strength of the connection of the bellows, which causes great adverse effects on the exhaust work of the automobile. The automobile bellows is effectively fixed and damped by the fixed shock-absorbing device 12. At the same time, the thermal deformation generated during the exhaust work of the bellows is effectively adjusted by the regulating effect of the hydraulic regulating cylinder 11. While preventing the automobile bellows from being thermally deformed and causing adverse effects on the exhaust work of the automobile, the practicality of the automobile bellows is further improved. The common automobile exhaust bellows are solved. In use, due to the simple design of the bellows connection, the fixation of the bellows is poor. Because the automobile bellows is not designed with a highly targeted structure to prevent thermal deformation, the automobile bellows is easily thermally deformed, which greatly reduces the practicality of the automobile bellows and also causes great adverse effects on the exhaust work of the automobile due to the thermal deformation of the bellows.
