Fixing structure for motor vehicle tail gas detection probe

Abstract

The invention relates to the technical field of motor vehicle tail gas detection auxiliary equipment and discloses a fixing structure for a motor vehicle tail gas detection probe. The fixing structure comprises a tail gas pipe. A fixing device is movably installed on the inner wall of the outlet end of the tail gas pipe through a formed groove. A fixing inner ring is fixedly installed in the fixing device through a connecting rod. The inner wall of the fixing inner ring is in threaded connection with an external thread arranged outside a supporting rod through a formed internal thread. The probe is fixedly installed at the end, located in the tail gas pipe, of the supporting rod. Fixing blocks with the two ends in clamped connection with the side wall of the tail gas pipe through clamping devices are movably installed on the upper portion of the fixing device. The fixing structure for the motor vehicle tail gas detection probe is convenient to detach, simple in structure, convenient to operate and convenient to use; the fixing inner ring is clamped with the interior of the tail gas pipe through the fixing device, when the tail gas pipe vibrates, the probe moves relative to the tail gas pipe accordingly, collisions between the probe and the inner wall of the tail gas pipe are avoided, and accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle exhaust detection auxiliary equipment, in particular to a fixing structure for a motor vehicle exhaust detection probe. Background technique [0002] Motor vehicle means "motor vehicle", which is a wheeled vehicle driven or drawn by a power plant, running on the road, used for passengers or (and) transporting goods or performing special operations, and some amusement facilities (such as electric cameras, etc.) Cars, electric scooters, electric bicycles, etc.), can be classified into automobiles and automobile trains, motorcycles and mopeds, tractor transport units, wheeled special machinery vehicles and electric vehicles, etc. [0003] Automobile exhaust contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. Automobile exhaust is one of motor vehicle exhaust. ...

AI Technical Summary

Problems solved by technology

[0007]Aiming at the deficiencies in the prior art, the present invention provides a fixed structure for a motor vehicle exhaust detection probe, which is easy to disassemble, ingenious in conception, reasonable in design and simple in structure. Easy to operate, easy to use, prevent the probe from colliding with the inner wall of the exhaust pipe, improve accuracy, adapt to different exhaust pipe diameters within a certain range, and increase practicability, which solves the problem that most of the existing motor vehicle exhaust detection probes are Manually holding the probe fixing rod for detection may easily cause collisions between the probe and the inner wall of the exhaust pipe, resulting in inaccurate detection results
