Abstract
A local heat insulation structure of a passenger car exhaust pipe is characterized in that two or more than two horse-riding bolts are welded on the passenger car exhaust pipe, and the threads of the two ends of each horse-riding bolt are arranged upwards; the heat shield is designed into a half-surrounding structure and is fixed on a saddle bolt by a nut, the heat shield is designed into a proper length according to the size of a required heat insulation object, and the lower end of the heat shield is better than the diameter of the exhaust pipe 2/3. The local heat insulation structure of the passenger car exhaust pipe has the characteristics of simple structure, convenience in installation and the like, can randomly design the riding bolt with proper size and thread length according to the diameter size of the exhaust pipe and the installation position of the heat insulation cover, can select proper welding positions according to parts needing heat insulation of the heat insulation cover, is suitable for the exhaust pipes with different outer diameter sizes, can prevent heat radiation, and avoids aging and burning of sensing data lines, conducting wires and the like, thereby improving the use safety of the passenger car.
Description
Technical Field
The utility model relates to a passenger car accessory, in particular to a local heat insulation structure of a passenger car exhaust pipe.
Background
At present, a large number of sensing data lines, conducting wires and the like are arranged on the surrounding edge of the exhaust pipe of the passenger car. The heat radiation that tail gas produced among the passenger train driving process blast pipe for sensing data line, conductor wire etc. easily produce ageing, cause the burn even, influence the safety in utilization of passenger train.
Disclosure of Invention
The utility model aims to provide a local heat insulation structure of a passenger car exhaust pipe, which has a simple structure and is safe to use.
The utility model discloses a local heat insulation structure of a passenger car exhaust pipe, which is characterized in that two or more than two horseback bolts are welded on the passenger car exhaust pipe, and the threads of the two ends of each horseback bolt are arranged upwards; the heat shield is designed to be a semi-surrounding structure and is fixed on a saddle bolt by a nut, the heat shield is designed to have a proper length according to the size of a required heat insulation object, and the lower end of the heat shield is better to be capable of wrapping the diameter of the exhaust pipe 2/3.
The local heat insulation structure of the passenger car exhaust pipe has the characteristics of simple structure, convenience in installation and the like, can randomly design the riding bolt with proper size and thread length according to the diameter size of the exhaust pipe and the installation position of the heat insulation cover, can select proper welding positions according to parts needing heat insulation of the heat insulation cover, is suitable for the exhaust pipes with different outer diameter sizes, can prevent heat radiation, and avoids aging and burning of sensing data lines, conducting wires and the like, thereby improving the use safety of the passenger car.
