Description

Anti-scalding probe placing rack for motor vehicle exhaust detection

Technical Field

The utility model relates to the technical field of tail gas detection, in particular to an anti-scald probe placing rack for motor vehicle tail gas detection.

Background

The components and the concentration of the exhaust gas discharged when the motor vehicle is in idle speed or working condition are analyzed and measured on site or a running test bed. A large amount of harmful waste gas discharged when a motor vehicle runs is a main flowing pollution source of environmental air, and tail gas detection of the harmful waste gas is an important component of environmental air pollution monitoring. The items tested were mainly carbon monoxide, nitrogen oxides, hydrocarbons, photochemical oxidants and smoke intensity.

Present tail gas need fix the probe in the tailpipe at the testing process, utilizes the probe to detect and extract the sample, nevertheless has the impact force during exhaust emissions, consequently dashes out the probe easily, and inconvenient detection volume for this we have proposed a motor vehicle exhaust detects prevents scalding probe rack.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides an anti-scald probe placing rack for motor vehicle tail gas detection.

The utility model provides the following technical scheme: an anti-scald probe placing rack for motor vehicle exhaust detection comprises a fixed pipe, a sampling head, a fixed ring, a supporting rod, a connecting rod, a moving ring, a buffer spring and a positioning ring;

the sampling head is installed in the one end of fixed pipe, gu fixed ring installs in solid fixed ring's the outside, the bracing piece is equipped with the multiunit and installs in solid fixed ring's the outside through the pivot, shift ring and solid fixed ring sliding connection, the connecting rod is equipped with the multiunit and installs in the outside of shift ring through the pivot, the other end of connecting rod rotates through pivot and bracing piece to be connected, the holding ring is installed on fixed pipe, and buffer spring sets up on the fixed pipe between shift ring and holding ring.

Preferably, the other end of the fixed pipe is provided with a threaded interface.

Preferably, when the buffer spring is not compressed, the support rod on the fixing ring is in an open state.

Preferably, the connecting rod is kept away from the one end of solid fixed ring and is installed the pivot, the bracing piece is connected with the connecting rod through the pivot.

Preferably, the positioning ring is detachably mounted on the fixed pipe through a screw.

Compared with the prior art, the utility model has the following beneficial effects:

this probe rack is prevented scalding in motor vehicle exhaust gas detection, under buffer spring's elasticity, can make the shifting ring remove to utilize the connecting rod to strut the bracing piece, make the bracing piece card in the tail gas pipe, receive tail gas impact and drop when so avoiding detecting, collect the messenger, only need adjust the screw rod on the holding ring, and remove the holding ring, alright make buffer spring reconversion, and the bracing piece lacks the support and contracts, so take off.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

In the figure: 1. a fixed tube; 2. a probe; 3. a fixing ring; 4. a support bar; 5. a connecting rod; 6. a moving ring; 7. a buffer spring; 8. a retaining ring.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure, and in order to keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known parts of the disclosure are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

Referring to fig. 1, an anti-scald probe placement rack for motor vehicle exhaust detection comprises a fixed tube 1, a sampling head 2, a fixed ring 3, a support rod 4, a connecting rod 5, a moving ring 6, a buffer spring 7 and a positioning ring 8, wherein the sampling head 2 is installed at one end of the fixed tube 1, the fixed ring 3 is installed at the outer side of the fixed ring 1, the support rod 4 is provided with a plurality of groups and is installed at the outer side of the fixed ring 3 through a rotating shaft, the moving ring 6 is slidably connected with the fixed ring 1, the connecting rod 5 is provided with a plurality of groups and is installed at the outer side of the moving ring 6 through a rotating shaft, the other end of the connecting rod 5 is rotatably connected with the support rod 4 through a rotating shaft, the positioning ring 8 is installed on the fixed tube 1, the buffer spring 7 is arranged on the fixed tube 1 between the moving ring 6 and the positioning ring 8, under the elastic force of the buffer spring 7, the moving ring can move, and the support rod 4 is opened by the connecting rod 5, make 4 cards of bracing piece in the tail gas pipe, receive the tail gas impact and drop when so avoiding detecting, collect the messenger, only need adjust the screw rod on the holding ring 8 to remove holding ring 8, alright make buffer spring 7 reconversion, and bracing piece 4 lacks the support and the shrink, so take off.

Threaded connection is installed to the other end of fixed pipe 1, conveniently with the pipe connection, utilizes sampling head 2 to sample tail gas during the detection to transmit through fixed pipe 1.

When buffer spring 7 is uncompressed, bracing piece 4 on solid fixed ring 3 is the state of opening, so only need to fix pipe 1 and insert in the tail gas pipe, and the pipe wall of fixed pipe 1 can extrude bracing piece 4, in bracing piece 4 all got into the tail gas pipe, buffer spring 7 can produce elasticity because of the extrusion of shift ring 6 to act on shift ring 6, make connecting rod 5 support the state of bracing piece 4, place bracing piece 4 and lose tension.

Connecting rod 5 keeps away from the one end of solid fixed ring 3 and installs the pivot, bracing piece 4 is connected with connecting rod 5 through the pivot, utilizes bracing piece 4 to control open scope to connecting rod 5, can adjust according to the demand.

The holding ring 8 is through screw rod demountable installation on fixed pipe 1, conveniently collects, and after the screw rod on the holding ring 8 was become flexible, the holding ring 8 was opened by buffer spring 7 bullet, and shift ring 6 lost power this moment, leads to connecting rod 5 powerless to support bracing piece 4 to make bracing piece 4 shrink, in order conveniently to take out.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents of the utility model may be made by those skilled in the art within the spirit and scope of the utility model, and such modifications and equivalents should also be considered as falling within the scope of the utility model.
