Description
Technical Field
The utility model relates to the field of automobile detection, in particular to a multipurpose gas collecting head for detecting automobile exhaust.
Background
The tail gas detection is the most important in the annual inspection project of automobiles, and the existing sampling probes are also divided into various specifications corresponding to different detection equipment and vehicle specifications. In the in-service use process, operating personnel puts into the vehicle blast pipe with the probe, but because the sampling probe scheduling problem that mismatches, sampling or data or because of the incomplete inaccurate condition of data that exists need collect the sample repeatedly for a long time, the inconvenience that from this brings makes staff intensity of labour increase, and loaded down with trivial details flow also influences detection efficiency very much.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the multipurpose gas collecting head for detecting the automobile exhaust, which has the advantages of simple structure, safety, reliability and convenient use.
The equipment comprises a gas collecting head, wherein gas collecting channels are arranged on the gas collecting head in an array manner;
the rear part of the gas collecting head is fixedly connected with a gas collecting hose, and elastic retaining pieces are arranged on the gas collecting hose relatively.
The tail end of the gas collection hose is fixedly connected with a supporting pipe, the supporting pipe is a straight through pipe, and the outer wall surface of the supporting pipe is integrally provided with threads;
the supporting pipe is screwed with an exhaust plug.
The exhaust plug is provided with a threaded sleeve in the middle, and the front end head of the exhaust plug is smoothly contracted inwards and downwards and is in a horn mouth shape.
Furthermore, an anti-skid rubber mat is fixedly arranged on the wall surface of the front end head of the exhaust plug.
Furthermore, the number of the elastic blocking pieces is two, and the two elastic blocking pieces are arranged oppositely.
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, solves the problem of unsmooth collection of tail gas detection samples in the prior art through the simple structure, realizes efficient collection and rapid collection of gas, reduces the labor intensity of workers, and improves the detection efficiency through a simple process.

Detailed Description
Referring to fig. 1 and 2, the multipurpose gas collecting head for detecting automobile exhaust, provided by the utility model, comprises a gas collecting head 1, wherein gas collecting channels are arranged on the gas collecting head 1 in an array manner;
the rear part of the gas collecting head 1 is fixedly connected with a gas collecting hose 3, and the gas collecting hose 3 is relatively provided with an elastic separation blade 2.
The tail end of the gas collection hose 3 is fixedly connected with a supporting pipe which is a straight through pipe, and the outer wall surface of the supporting pipe is integrally provided with threads;
an exhaust plug 4 is screwed on the supporting pipe.
The exhaust plug 4 is provided with a threaded sleeve in the middle, and the front end head of the exhaust plug is smoothly contracted inwards and downwards and is in a horn mouth shape.
Furthermore, an anti-skid rubber mat 5 is fixedly arranged on the wall surface of the front end head of the exhaust plug 4.
Furthermore, the number of the elastic blocking pieces 2 is two, and the two elastic blocking pieces 2 are arranged oppositely.
Preferably, the resilient flap 2 is in the form of a metal sheet.
When the exhaust pipe is a special-shaped exhaust pipe or the pipe diameter is larger, the exhaust plug 4 can be screwed to the end of the supporting pipe, namely the end close to the gas collecting head 1, and automobile exhaust enters detection equipment through the gas collecting head 1, the gas collecting hose 3 and the supporting pipe to efficiently collect a sample.
While there have been shown and described what are at present considered the fundamental principles and essential features of the utility model and its advantages, it will be apparent to those skilled in the art that the utility model is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
