Detailed Description

The technical scheme of the utility model is further described with the attached drawings:

an anti-deformation automobile exhaust corrugated pipe comprises a corrugated pipe body 1, a protective shell 3 is fixedly sleeved at the upper end of the outer wall of the corrugated pipe body 1, a steel wire ring 4 is arranged between the inner wall of the protective shell 3 and the outer wall of the corrugated pipe body 1, can absorb the transverse expansion of the corrugated pipe and reduce the damage of the transverse expansion to the corrugated pipe, the lower end of the outer wall of the corrugated pipe body 1 is sleeved with an expansion spring 2 below a protective shell 3 to absorb the longitudinal vibration of the expansion of the corrugated pipe body and reduce the damage of the vibration to the corrugated pipe, the upper end of the expansion spring 2 is connected with the lower end of the protective shell 3, a shoulder 5 is arranged on the inner wall of the corrugated pipe body 1 and positioned in the protective shell 3, the bead 5 divides the steel wire ring 4 into an upper part and a lower part, the arrangement of the shoulder 5 reinforces the corrugated pipe body 1, and the steel wire ring 4 is divided into two independent parts, so that the deformation of the steel wire ring is increased, and the expansion of the corrugated pipe body 1 is better protected.

In this embodiment, preferably, the corrugated pipe body 1 is a stainless steel corrugated pipe.

In this embodiment, preferably, a heat insulation layer is disposed on the inner wall of the corrugated pipe body 1.

In this embodiment, it is preferable that one end of the bead ring 4 is fixed to the inner wall of the protective case 3, and the other end is fixed to the outer wall of the bellows body 1.

In this embodiment, it is preferable that a heat dissipation fin is disposed outside the extension spring 2.

In this embodiment, preferably, the upper end of the protective shell 3 is disposed beyond the upper end of the bellows body 1.

In this embodiment, the shoulder 5 is preferably located in the middle of the protective shell 3.

When the corrugated pipe heating device works, two ends of the corrugated pipe body 1 are respectively inserted into an exhaust port of an engine and an air inlet of an exhaust pipe, when the engine generates heat, the corrugated pipe body 1 expands to provide acting force for the bead rings 4 and the extension springs 2, the bead rings 4 offset transverse acting force through elastic force generated by compression, and the extension springs 2 offset longitudinal acting force through tensile force generated by extension.

In conclusion, the corrugated pipe absorbs the transverse vibration generated by expansion with heat and contraction with cold by the matching use of the steel wire ring 4 and the protective shell 3, reduces the damage of stress generated by expansion with heat and contraction with cold to the corrugated pipe, prolongs the service life of the corrugated pipe and improves the working efficiency of the corrugated pipe; the longitudinal vibration generated during expansion with heat and contraction with cold is absorbed by the cooperation of the telescopic spring 2, so that the damage of the vibration to the corrugated pipe is reduced, and the condition that the automobile cannot normally run due to the damage of the corrugated pipe is avoided; the problem that the common automobile corrugated pipe cannot absorb vibration generated during expansion with heat and contraction with cold is solved.
