Description

Technical Field

[0001] This utility model relates to the field of exhaust gas collection technology, specifically a portable exhaust gas collector for motor vehicles. Background Technology

[0002] An exhaust gas collector is a specialized device used to collect and analyze exhaust gases emitted by vehicles, industrial equipment, and other sources. It is typically connected to the exhaust source (such as a car exhaust pipe) via a specific sampling probe. The exhaust gas is introduced into the collection device, and after being processed by filtration, condensation, and adsorption, the gas sample is stored in a container or directly transferred to an analytical instrument to detect the components (such as carbon monoxide, nitrogen oxides, particulate matter, etc.) and concentrations of pollutants.

[0003] In current technologies, exhaust gases need to be tested after they are emitted. Currently, the collection equipment is placed manually at the exhaust outlet to collect the gases. This method cannot quickly open the collection port, which can lead to air mixing and affect the accuracy of subsequent tests.

[0004] Therefore, it is necessary to provide a portable exhaust gas collector for motor vehicles to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a convenient exhaust gas collector for motor vehicles, which solves the problem that currently, exhaust gas needs to be tested after it is emitted. In this method, the collection device is placed manually at the exhaust outlet, which cannot be opened quickly, resulting in air mixing and affecting the accuracy of subsequent tests.

A spring is fixedly connected to the bottom of the inner wall of the circular groove, and a locking block is fixedly connected to the top of the spring. The locking block is in contact with the surface of the limiting rod.

[0009] Preferably, a support plate is fixedly connected to the surface of the main rod of the exhaust gas collector, and the support plate is rotatably connected to the rotating rod.

[0010] Preferably, there are several support plates, which are evenly distributed in a straight line.

[0011] Preferably, the bottom of the card block is slidably connected to a slide rod, and the bottom of the slide rod is fixedly connected to the bottom of the inner wall of the circular groove.

[0012] Preferably, both sides of the card block are connected to sliders, and both sides of the inner wall of the circular groove are provided with sliding grooves that are slidably connected to the sliders.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows for efficient collection of exhaust gas.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 A portable exhaust gas collector for motor vehicles includes an exhaust gas collector main rod 1, a fixed plate 2 fixedly connected to the top of the exhaust gas collector main rod 1, a support rod 3 fixedly connected to the top of the fixed plate 2, a limiting plate 4 fixedly connected to the top of the support rod 3, a collection component 5 provided at the bottom of the limiting plate 4, a rotating rod 6 provided on the left side of the exhaust gas collector main rod 1, and an operating rod 7 fixedly connected to the bottom of the exhaust gas collector main rod 1, with a fixing component 8 provided inside the operating rod 7. Collection component 5 is used to collect exhaust gas; The fixed component 8 is used to control the collection component 5.

[0018] Please see Figure 3 The collection component 5 includes a telescopic collection tube 51, which is connected to the bottom of the limiting plate 4. The top of the limiting plate 4 is connected to an air pipe 52, and a sealing plate 53 is provided on the top of the air pipe 52. The sealing plate 53 is fixedly connected to the rotating rod 6.

[0019] Furthermore, by setting up the collection component 5, the exhaust gas can be effectively and comprehensively collected and treated, ensuring that the exhaust gas can be smoothly guided into the internal space of the telescopic collection pipe 51. This not only provides great convenience for subsequent exhaust gas detection work, but also greatly improves the convenience and efficiency of the user in the operation process.

[0020] Please see Figure 4 The fixing component 8 includes a limiting rod 81, which is fixedly connected to the bottom of the rotating rod 6. The surface of the operating rod 7 is provided with a fixing groove 82, and the bottom of the inner wall of the fixing groove 82 is provided with a circular groove 83. The bottom of the inner wall of the circular groove 83 is fixedly connected with a spring 84, and the top of the spring 84 is fixedly connected with a locking block 85. The locking block 85 is in contact with the surface of the limiting rod 81.

[0021] Furthermore, by setting the fixing component 8, a continuous and stable clamping function for the locking block 85 can be achieved, ensuring that the locking block 85 can be firmly locked in the side wall position of the limit rod 81 for a long time, thereby effectively ensuring the stability of the locking block 85, avoiding the loosening problem that may occur during use, and greatly improving the user's operating experience and safety.

[0022] Please see Figure 2 A support plate 9 is fixedly connected to the surface of the main rod 1 of the exhaust gas collector, and the support plate 9 is rotatably connected to the rotating rod 6.

[0023] Furthermore, the support plate 9 structure enables precise limit control of the rotating rod 6, ensuring its high stability during operation and effectively reducing its wobbling. This provides users with a stable and reliable operating environment, making the entire process smoother and more efficient.

[0024] Please see Figure 1 There are several support plates 9, which are evenly distributed in a straight line.

[0025] Furthermore, by setting the number of support plates 9 to several, multiple key positions of the rotating rod 6 can be supported in all directions, greatly improving the support efficiency and ensuring that the rotating rod 6 can be effectively supported in each position, thereby further optimizing the user's operating experience and making the whole system more stable and reliable.

[0026] Please see Figure 4 The bottom of the locking block 85 is slidably connected to a slide rod 10, and the bottom of the slide rod 10 is fixedly connected to the bottom of the inner wall of the circular groove 83.

[0027] Furthermore, the sliding rod 10 effectively limits the bottom of the locking block 85, ensuring that the locking block 85 maintains high stability during operation, effectively preventing the locking block 85 from shaking, improving overall stability, and providing users with a safe and reliable operating environment.

[0028] Please see Figure 4 Both sides of the card block 85 are connected to sliders 11, and both sides of the inner wall of the circular groove 83 are provided with sliding grooves 12 that are slidably connected to the sliders 11.

[0029] Furthermore, the slider 11 device enables the locking block 85 to slide stably and vertically inside the circular groove 83, effectively reducing the shaking of the locking block 85, ensuring the stability and accuracy of the locking block 85 during the sliding process, and greatly improving the user's ease of operation and the overall performance of the system.

[0030] The specific implementation process of this utility model is as follows: During the exhaust gas collection process, the air pipe 52 first needs to be accurately moved to the specific location where the exhaust gas is discharged. Then, the user needs to manually operate the rotating rod 6 to rotate 90 degrees clockwise or counterclockwise. The purpose of this action is to enable the rotating rod 6 to effectively drive the limiting rod 81, thereby making it tightly press against the locking block 85. The special arc design of the top of the locking block 85 plays a key role in this process. It can guide the locking block 85 to move downward along the predetermined trajectory. As the locking block 85 descends, the limiting rod 81 gradually and completely disengages from the internal structure of the circular groove 83. Immediately afterwards, the rotating rod 6 continues to drive the sealing plate 53 to rotate 90 degrees. The rotation of the 6-degree angle ensures that the trachea 52 is fully opened, creating conditions for the smooth entry of exhaust gas. The exhaust gas then enters the telescopic collection tube 51, gradually filling it to achieve the optimal collection state. After the exhaust gas collection is completed, the user needs to rotate the rotating rod 6 in the opposite direction to return the sealing plate 53 to its initial position, sealing the top of the trachea 52 tightly. This step not only ensures the integrity of the collection process but also facilitates subsequent sample analysis and storage. Through this series of carefully designed operating steps, efficient and accurate exhaust gas collection and sampling results are ultimately achieved, providing reliable technical support for environmental monitoring and data collection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
