Description

Anti-drop double-end sampling probe for tail gas detection

Technical Field

The utility model relates to the field of automobile detection, in particular to an anti-drop double-head sampling probe for tail gas detection.

Background

The exhaust detection is the most important part of the motor vehicle detection, and the existing exhaust detection equipment is various, wherein a professional detection mechanism usually adopts special analyzers of different models, and generally comprises a host, a filter, a sampling probe and the like. However, there is certain inconvenience in current sampling probe in the use, wherein mainly include when tail gas is detected, need the user to continue to hold sampling probe and carry out the sample and continue the selective examination, be an unnecessary waste to the manpower, more important, can seriously influence operator's personal health. In addition, along with the progress and development of scientific technology, the discharge capacity and the exhaust form of the automobile are different, the automobile market with double exhaust pipes is more and more, the detection accuracy is considered, the form of respective spot check is usually adopted at present, but the efficiency is lower.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide the anti-drop double-head sampling probe for tail gas detection, which has the advantages of simple structure, safety, reliability and convenience in use.

The equipment comprises a main pipeline, wherein two probe hoses are communicated with the main pipeline through a pipeline;

a sampling probe is arranged at the end position of the probe hose;

the outer wall surface of the sampling probe is provided with a spring piece which is in a bent metal sheet form;

and a spring is arranged between the spring piece and the outer wall surface of the probe.

Furthermore, at least two spring pieces are arranged on each sampling probe, and the two spring pieces are arranged oppositely.

Furthermore, the outer surface of the spring piece is fixedly provided with a friction plate.

The utility model has the beneficial effects that: the tail gas detection device is simple in structure, convenient to use, low in manufacturing cost and easy to maintain, various problems existing in tail gas detection in the prior art are solved through the simple structure, high-efficiency and high-quality tail gas detection is realized, the sampling probe is locked in a tail gas pipeline through the matching of the spring piece and the friction plate, the sampling probe is easy to disassemble and assemble, and unnecessary manual work is avoided.

The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1 and 2, the anti-drop double-head sampling probe for tail gas detection comprises a main pipeline 5, wherein two probe hoses 4 are communicated with an upper pipeline of the main pipeline 5;

a sampling probe 1 is arranged at the end of the probe hose 4;

the outer wall surface of the sampling probe 1 is provided with a spring piece 3, and the spring piece 3 is in a bent metal sheet form;

and a spring 6 is arranged between the spring piece 3 and the outer wall surface of the probe.

Preferably, a sealing cap is movably arranged on the sampling probe 1.

Furthermore, at least two spring pieces 3 are arranged on each sampling probe 1, and the two spring pieces 3 are arranged oppositely.

Furthermore, a friction plate 2 is fixedly arranged on the outer surface of the spring piece 3.

Preferably, the surface of the friction plate 2 is in the form of protrusions arranged in an array.
