Connecting device for automobile exhaust pipe

Abstract

The invention discloses a connecting device for an automobile exhaust pipe. The invention is provided with a three-stage shock-absorbing structure, which can effectively reduce the vibration of the automobile exhaust pipe, avoid equipment damage and exhaust pipe falling off, and is provided with a first connecting head And the second connector enables the present invention to be quickly assembled and disassembled with the exhaust pipe, reducing the loading and unloading burden of the staff, and improving efficiency. The first connector safety device and the second connector safety device are provided to improve the fixing strength of the equipment. The unique muffler chamber can weaken the sound of the gas, thereby reducing the noise of the car. The exhaust gas purifier can effectively purify the exhaust gas of the car to avoid the discharge of toxic and harmful gases. It is equipped with a filter to absorb carbon dioxide and reduce carbon dioxide emissions. The greenhouse effect is avoided, and the invention has strong earthquake resistance. Convenient loading and unloading, firm installation, high degree of exhaust gas purification, effective noise reduction and other beneficial effects.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary equipment; in particular, it relates to a connecting device for an automobile exhaust pipe. Background technique [0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust Pipe generally includes front exhaust pipe and rear exhaust pipe. Most of the existing exhaust pipes are connected by sleeve welding. This connection method is not only complicated and troublesome, but also difficult to disassemble and repair when the exhaust pipe fails. Most of the existing exhaust pipes use exhaust pipe hoses for shock absorption. This shock absorption belongs to the first-level shock absorption. The shock absorption efficiency is low, and the safety of th...

[0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust Pipe generally includes front exhaust pipe and rear exhaust pipe. Most of the existing exhaust pipes are connected by sleeve welding. This connection method is not only complicated and troublesome, but also difficult to disassemble and repair when the exhaust pipe fails. Most of the existing exhaust pipes use exhaust pipe hoses for shock absorption. This shock absorption belongs to the first-level shock absorption. The shock absorption efficiency is low, and the safety of the exhaust pipe cannot be effectively guaranteed. The trachea is damaged and falls off. At the same time, most of the purification devices connected to the exhaust pipe can only purify the exhaust gas, but cannot eliminate the purified carbon dioxide. Therefore, the carbon dioxide in the exhaust gas is discharged, leading to the greenhouse effect. At the same time, the existing exhaust gas Most of the exhaust pipes are not equipped with mufflers, and when the exhaust gas is discharged, it will produce a lot of noise. Most of the existing exhaust pipes are fixed by screws without safety devices. The screw fell off. Therefore, the emergence of an automobile exhaust pipe connection device with strong shock resistance, convenient loading and unloading, firm installation, high degree of exhaust gas purification, and effective noise reduction is imminent.
