Abstract
The utility model discloses a kind of fixed devices of riding tail gas sampling probe, the tensioning snap ring at connection cross bar both ends is symmetricly set on including connection cross bar and two, two tensioning snap rings with connect that cross bar is vertical to be connected, probe fixing clasp is connected with by connecting rod in each tensioning snap ring.The utility model structure is simple, and tail gas sampling probe can be effectively fixed on to the shaft core position of exhaust pipe, guarantees the stability and accuracy of sampling, and convenient for disassembly and assembly.
Description
Technical field
The utility model relates to technical field of automobile parts, and in particular to a kind of fixed dress of riding tail gas sampling probe
It sets and exhaust pipe.
Background technique
Riding tail gas sampling analysis instrument, is commonly used to measure the concentration and ingredient of motor vehicle exhaust emission, in measurement process
Need the sampling probe by tail gas sampling analysis instrument to be fixed on suitable position in exhaust pipe, thus guarantee sampling stability and
Accuracy.The fixed device of existing tail gas sampling probe, one is being fixed using bolt, such fixed form dismounting is got up
It is more inconvenient, and firmly excessive easily sampling probe is caused to damage.Another kind is the positioning method using cylindrical screw spring, this
Kind mode requires external cylindrical surface rationally to cooperate with tail gas pipe size, and compresses and use screw spring structure, manufactures and also compares
It is more complex.
Utility model content
The purpose of this utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of riding tail gas sampling spy
The fixed device of head and exhaust pipe.
In order to achieve the goal above, the fixed device of a kind of riding tail gas sampling probe provided by the utility model, including
Connection cross bar and two are symmetricly set on the tensioning snap ring at connection cross bar both ends, two tensioning snap rings with to connect cross bar vertical
Connection, each tensioning snap ring is interior to be connected with probe fixing clasp by connecting rod.
Preferably, the tensioning snap ring and probe fixing clasp are coaxially arranged.
Preferably, opening is had in the tensioning snap ring and probe fixing clasp.
The utility model also provides a kind of exhaust pipe, and the exhaust inside pipe wall is equipped with riding tail gas as described above and adopts
Sample probe fixing device.
Technical solution provided by the utility model has the benefit that
The utility model structure is simple, and tail gas sampling probe can be effectively fixed on to the shaft core position of exhaust pipe, guarantees
The stability and accuracy of sampling, and it is convenient for disassembly and assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model installs the structural schematic diagram after tail gas sampling probe；
The cross section and vertical section structure schematic diagram of Fig. 3 .1,3.2 for exhaust pipe.
In figure: connection cross bar 1 is tensioned snap ring 2, connecting rod 3, fixing clasp 4 of popping one's head in, tail gas sampling probe 5, exhaust pipe 6.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
The fixed device of a kind of riding tail gas sampling probe as shown in Figure 1, including connection cross bar 1 and two it is symmetrical
The tensioning snap ring 2 at connection 1 both ends of cross bar is set, two tensioning snap rings 2 with connect the vertical connection of cross bar 1, each tensioning blocks
Probe fixing clasp 4 is connected with by connecting rod 3 in ring 2.
Above-mentioned tensioning snap ring 2 and probe fixing clasp 4 are coaxially arranged.
With opening on above-mentioned tensioning snap ring 2 and probe fixing clasp 4.
The present embodiment also provides a kind of exhaust pipe, and 6 inner wall of exhaust pipe is equipped with riding tail gas as described above and adopts
Sample probe fixing device.
The specifically used method of the utility model are as follows:
Tail gas sampling probe 5 is passed through to simultaneously clamping from two probe fixing clasps 4 first, then by two tensioning snap rings
1 abutting 6 inner wall of exhaust pipe is put into exhaust pipe 6, and adjust its axial distance can be sampled to suitable position.
Other unspecified parts belong to the prior art.
