Technical Field

[0001] The present application relates to the technical field of gas detection, and in particular to an exhaust gas detection device. Background Art

[0004] In the actual exhaust gas detection process, the workbench cannot be adjusted to a suitable operating height according to the user's height, which is inconvenient to use. To this end, we propose an exhaust gas detection device. Summary of the Invention

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application provides a lifting and sliding workbench. When the height of the workbench needs to be adjusted, the drive motor is started, and the output shaft of the drive motor drives the connecting rod to rotate. When the connecting rod rotates, it drives the drive block to slide on the guide rail.

Therefore, it has good practicality.

When the test is completed, the exhaust gas collection barrel is connected to the exhaust port of the detector through the quick connector, and then the push-pull rod is pulled outward to reduce the pressure in the exhaust gas collection barrel, thereby allowing the exhaust gas in the detector to be discharged into the exhaust gas collection barrel for subsequent treatment;

[0020] 3. By arranging a support spring on the slide bar, the stability of the workbench during the lifting and sliding process can be enhanced, thereby reducing the shaking of the detector on the workbench. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present application is further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the present application discloses an exhaust gas detection device. Figure 1An exhaust gas detection device includes a base 1, a workbench 2, a detector 3 and a driving component 4.

[0025] The base 1 is provided with four self-locking universal wheels 11 at the bottom, located at the four corners of the base 1. Four vertically arranged slide bars 12 are fixedly connected to the upper surface of the base 1, located at the four corners of the upper surface of the base 1. The workbench 2 is arranged horizontally and slidably connected to the slide bars 12.

[0026] The driving member 4 is used to drive the workbench 2 to rise and fall and slide. The driving member 4 includes a guide rail 41, a driving block 42, a connecting rod 43, and a driving motor 44. The guide rail 41 is welded and fixed to the side wall of the workbench 2. The guide rail 41 is a waist-shaped guide rail 41, which is arranged horizontally along the length direction. The driving block 42 is slidably connected to the guide rail 41. One end of the connecting rod 43 is hinged to the driving block 42. A support frame 14 is welded to the base 1. To avoid affecting the rotation of the connecting rod 43, the support frame 14 is set on one side of the base 1 along the width direction. The housing of the driving motor 44 and the support frame 14 are fixedly connected by screws. The output shaft of the driving motor 44 and the end of the connecting rod 43 away from the driving block 42 are fixedly connected by a shaft sleeve. The driving motor 44 drives the connecting rod 43 to rotate. When the connecting rod 43 rotates, it drives the driving block 42 to slide in the guide rail 41, thereby driving the workbench 2 to rise and fall. A support spring 13 is sleeved on the slide bar 12, one end of the support spring 13 is fixedly connected to the base 1, and the other end is fixedly connected to the bottom of the workbench 2. The support spring 13 is always in a compressed state. The support spring 13 is provided to enhance the stability of the workbench 2 during the lifting and sliding process.

[0027] The detector 3 is mounted on the workbench 2. Its exhaust port is connected to an exhaust gas collection barrel 31 via a quick connector 35. A piston head 32 is slidably connected to the exhaust gas collection barrel, and a push-pull rod 33 is coaxially fixedly connected to the end of the piston head 32. A one-way valve 34 is installed at the air inlet of the detector 3.

[0028] The implementation principle of an exhaust gas detection device according to an embodiment of the present application is as follows: First, when the height of the workbench 2 needs to be adjusted to suit the needs of different detection personnel, the drive motor 44 is started. The output shaft of the drive motor 44 is fixedly connected to one end of the connecting rod 43 via a shaft sleeve, so the rotation of the drive motor 44 drives the connecting rod 43 to rotate. The other end of the connecting rod 43 is hinged to the drive block 42, so the rotation of the connecting rod 43 further drives the drive block 42 to slide within the guide rail 41. Since the guide rail 41 is welded and fixed to the side wall of the workbench 2, the sliding movement of the drive block 42 is converted into the lifting and sliding of the workbench 2 on the slide bar 12, thereby achieving the adjustment of the height of the workbench 2.

[0029] Secondly, during the exhaust gas detection process, the exhaust gas enters the detector 3 through the air inlet section of the detector 3 for detection. The one-way valve 34 provided in the air inlet section can prevent the exhaust gas from flowing back, ensuring the accuracy of the detection. After the detection is completed, the exhaust gas needs to be discharged through the exhaust port. At this time, the exhaust gas collection cylinder 31 is connected to the exhaust port of the detector 3 through the quick connector 35. Then pull the push-pull rod 33 outward, and the piston head 32 moves accordingly, reducing the pressure in the exhaust gas collection cylinder 31, so that the exhaust gas in the detector 3 is discharged into the exhaust gas collection cylinder 31 for subsequent processing.

[0030] Finally, the four self-locking universal wheels 11 on the bottom of the base 1 allow the exhaust gas detection device to be easily moved between different locations. When the device needs to be fixed, simply lock the self-locking universal wheels 11. Furthermore, the support spring 13 mounted on the slide bar 12 is always compressed, enhancing the stability of the workbench 2 during lifting and sliding, thereby reducing the shaking of the detector 3 on the workbench 2 and improving detection accuracy.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
