Description

Technical Field

[0001] The utility model belongs to the field of tail gas detection equipment, and particularly relates to an auxiliary device for tail gas detection. Background Art

[0002] The auxiliary device for exhaust gas detection is a machine used to monitor and measure the exhaust gas components emitted by vehicles. However, the exhaust gas detection equipment in the prior art has the problem that the existing auxiliary device for exhaust gas detection usually has no shock absorption function in actual use. This is because there is a lack of shock-absorbing and fixed parts. The lack of shock-absorbing and fixed parts will not only lead to the above problems, but also there may be certain inconveniences in the way the existing auxiliary device for exhaust gas detection is installed on the exhaust pipe. First, the existing auxiliary device for exhaust gas detection usually has no shock absorption function. During the detection process, the exhaust pipe will vibrate. For example, a device lacking a shock absorption function may not be able to effectively stabilize on the exhaust pipe, causing its position to change, thereby affecting the accuracy of the measurement. In addition, long-term use in a high-frequency vibration environment will also increase the risk of damage to the device itself. Secondly, the existing auxiliary device for exhaust gas detection is installed on the exhaust pipe. There are certain inconveniences in the way it is fixed. The lack of a suitable fixing method may cause the device to loosen or fall off, thereby affecting the reliability of the measurement results. Therefore, it is necessary to propose a new structure to solve the above technical problems. Summary of the invention

The support component includes a first column, a second column, and a buffer spring. The interior of the first column is designed as a receiving cavity. A buffer spring is installed inside the first column. One end of the buffer spring away from the first column is connected to the lower end of the second column. When the exhaust pipe of an automobile vibrates during exhaust gas detection, these vibrations may be transmitted to the detection housing and the auxiliary device for exhaust gas detection, resulting in instability of the auxiliary device for exhaust gas detection. At this time, through the support component, the transmission of the exhaust pipe vibration can be effectively reduced, and the stability of the auxiliary device for exhaust gas detection can be improved.

[0010] As a preferred embodiment, fixing members are symmetrically installed at the right edge of the outer surface of the detection housing. The fixing member includes a knob, a threaded rod, and an arc-shaped plate. The upper end of the threaded rod is installed with a knob. One end of the threaded rod away from the knob is installed with an arc-shaped plate through a bearing. The inner surface of the arc-shaped plate abuts against the outer surface of the automobile exhaust pipe.

[0024] See also Figure 1 , Figure 3 As an embodiment of the present utility model: a bracket 200 is installed on the left edge of the upper surface of the bottom plate 100, the interior of the bracket 200 is designed as a receiving cavity, a screw rod 210 is installed inside the bracket 200, the upper end of the screw rod 210 passes through the upper surface of the bracket 200, and the outer surface of the screw rod 210 is provided with a thread;

[0025] A slider 220 is slidably installed on the outer surface of the bracket 200, and the slider 220 is threadedly connected to the screw rod 210. A mounting rod 300 is installed at the center of the outer surface of the slider 220, and a display control board 310 is installed on the right half of the outer surface of the mounting rod 300. A control system is implanted in the display control board 310 through a single-chip microcomputer;

[0026] Two support components 500 are installed on the lower surface of the installation rod 300. The two support components 500 have the same structure. The support component 500 includes a first column 510, a second column 530, and a buffer spring 520. The inside of the first column 510 is designed as a receiving cavity. The buffer spring 520 is installed inside the first column 510. One end of the buffer spring 520 away from the first column 510 is connected to the lower end of the second column 530;

[0027] The second column 530 is movably installed inside the first column 510. One end of the second column 530 away from the buffer is connected to the outer surface of the installation rod 300. The detection housing 400 has a U-shaped structure. The right end of the detection housing 400 is open. A gas detection sensor 410 is installed at the center position of the left inner wall inside the detection housing 400. The gas detection sensor 410 is electrically connected to the display control board 310 through a wire;

[0028] The model of the gas detection sensor 410 is SGA-700B-co;

[0029] When in use, the user first pinches the screwing rod 210 and then rotates the screwing rod 210. The rotation of the screwing rod 210 then drives the slider 220 on the outer surface of its bracket 200 to move up and down. When the slider 220 moves up and down, the installation rod 300 and the detection component will also move up and down accordingly. When the installation rod 300 moves up and down, the second column 530 connected to it will also move along the receiving cavity inside the first column 510. The second column 530 will drive the buffer spring 520 at its lower end to move up and down. The user can adjust the detection component to be parallel to the position of the exhaust pipe to be detected through the screwing rod 210 and then proceed with the next detection. Moreover, the exhaust pipe of the vehicle will vibrate during the exhaust detection, and these vibrations may be transmitted to the detection housing 400 and the auxiliary device for exhaust gas detection, resulting in instability of the auxiliary device for exhaust gas detection. At this time, through the buffer spring 520 inside the support component 500, the transmission of the exhaust pipe vibration can be effectively reduced (but not completely eliminated), improving the stability of the auxiliary device for exhaust gas detection.

[0030] Please refer to Figure 1 、 Figure 2 As an embodiment of the present invention: Fixing members 420 are symmetrically installed on the right edge of the outer surface of the detection housing 400. The fixing member 420 includes a knob 422, a threaded rod 421, and an arc-shaped plate 423. The upper end of the threaded rod 421 is installed with a knob 422. One end of the threaded rod 421 away from the knob 422 is installed with an arc-shaped plate 423 through a bearing. The inner surface of the arc-shaped plate 423 abuts against the outer surface of the vehicle exhaust pipe;

[0031] When in use, align the opening at the right end of the detection shell 400 with the exhaust pipe, and then clamp the detection shell 400 on the outer surface of the exhaust pipe (but the maximum diameter of the exhaust pipe must not be larger than the inner diameter of the detection shell 400). Then, the user pinches the knob 422 and turns the knob 422. The knob 422 drives the threaded rod 421 to rotate and then drives the arc plate 423 to move toward the exhaust pipe. Both fixing parts 420 are operated in this way to complete the fixation of the detection shell 400 and the exhaust pipe. Then, when the exhaust pipe discharges exhaust gas, the gas detection sensor 410 receives the data, and then it is processed and displayed by the display control board 310 to complete the detection. Because the fixing part 420 can conveniently fix the auxiliary device on the outer surface of the exhaust pipe, this fixing method can simplify the installation process and save time and labor. At the same time, the fixing part 420 can firmly fix the auxiliary device on the exhaust pipe and prevent it from loosening or falling off during the detection process. This can ensure that the auxiliary device is correctly in the detection position and maintain accurate measurement results.
