Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to a device for recording automobile exhaust gas detection data. Background Art

[0002] During the annual inspection of automobiles, the exhaust gas needs to be detected. Usually, an exhaust gas detector is used for detection. When the exhaust gas detector is in use, the sampling probe needs to be inserted into a fixed position inside the automobile exhaust pipe, generally with a penetration length of not less than 100 mm, and it needs to be kept for a fixed time and cannot be removed instantaneously, and then the instrument records the value.

[0003] After retrieval, the utility model with the publication number of CN213337546U provides a fixing device for an exhaust gas detector. The collar is sleeved outside the automobile exhaust pipe. The pull ring is loosened, and under the elastic force of the spring, the clamping plate clamps outside the automobile exhaust pipe, so that the collar is fixedly installed outside the automobile exhaust pipe, that is, the sampling probe is stably inserted inside the automobile exhaust pipe, and the sampling probe is not likely to move outside the exhaust pipe during detection, ensuring the accuracy of detection.

[0004] This device still has the following disadvantages during use: when in use, the probe is fixed by two clamping plates, but the probe is connected to the baffle, and the baffle is located at one end of the exhaust pipe, which makes the exhaust gas flow have resistance and is likely to seal one end of the exhaust pipe, affecting the engine operation, and the instrument needs to be placed on an additional table and chair during use, making it more troublesome to use outdoors. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the prior art that the probe is connected to the baffle, and the baffle is located at one end of the exhaust pipe, which makes the exhaust gas flow have resistance and is likely to seal one end of the exhaust pipe, affecting the engine operation, and the instrument needs to be placed on an additional table and chair during use, making it more troublesome to use outdoors, and to propose a device for recording automobile exhaust gas detection data.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0016] In a possible design, rotating seats are fixedly arranged at the four corners of the bottom of the detector body. The top of the support leg is rotatably arranged in the rotating seat and abuts against one side of the rotating seat after being opened for limiting.

[0017] In this application, during use, pull up the detection head upwards to make the detection head disengage from the two clamping blocks. During the process of pulling up the detection head, the plug can be driven to rotate on the detector body. Then take out the detection head from the plug and insert it into the exhaust pipe of the vehicle to be tested until the side wall of the exhaust pipe is located between the two fixing plates. Then rotate the bolt. The rotation of the bolt can move on the L-shaped rod, drive the sliding plate to move, and drive the abutting rod to pass through the fixing plate and abut against the exhaust pipe, so as to fix the detection head in the exhaust pipe;
