Description

Technical Field

[0001] This utility model relates to the technical field of diesel engine testing, specifically to a special testing device for diesel engines. Background Technology

[0002] Diesel engines are advantageous due to their high torque and good fuel economy. Their operating process shares many similarities with gasoline engines, with each working cycle involving four strokes: intake, compression, power, and exhaust. Diesel engine exhaust gas testing typically uses a diesel exhaust gas analyzer. However, during exhaust gas testing, especially during factory testing and use, oil leaks can occur uncontrollably, causing oil to splatter uncontrollably. This not only hinders subsequent cleaning but also poses safety hazards to workers. Therefore, we have proposed a specialized testing device for diesel engines to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a specialized testing device for diesel engines that effectively protects and collects leaking oil during operation, preventing direct contact between the oil and workers, facilitating subsequent oil collection and cleaning, and improving practicality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special testing device for diesel engines, comprising a workbench, wherein two first protective plates are symmetrically and rotatably mounted on the top of the workbench via two second hinges, and two second protective plates are symmetrically and rotatably mounted on the top of the workbench via two first hinges. A top plate is attached to the top of each first protective plate and each second protective plate, and multiple first limiting plates are symmetrically and fixedly mounted on the bottom of the top plate. Each first limiting plate is attached to the outer side wall of each first protective plate and each second protective plate. Multiple through holes are opened in the middle area of ​​the workbench, and multiple fixing mechanisms are provided on the top of the workbench.

[0005] The fixing mechanism includes a fixing post that passes through one of the through holes. Two fixing screws are symmetrically screwed onto the fixing post, and the two fixing screws are tightly fitted to the top and bottom of the worktable, respectively.

[0006] Preferably, a plurality of second limiting plates are symmetrically fixedly installed on the top of the workbench, and each second limiting plate is respectively attached to the outer side wall of each first guard plate and second guard plate.

[0007] Furthermore, a first handle is fixedly installed at the top of the top plate.

[0008] Furthermore, each of the first protective plates has an observation window on its outer side wall.

[0009] Based on the aforementioned scheme, a collection trough is provided on the workbench, and a door is opened on the outer wall of the collection trough, with a second handle installed on the door.

[0010] Furthermore, multiple support pillars are fixedly installed around the bottom of the collection tank.

[0011] Compared with the prior art, this utility model provides a dedicated testing device for diesel engines, which has the following advantages:

[0012] This specialized testing equipment for diesel engines uses a first and second guard plate to isolate the oil in the diesel engine. A top plate and a first limiting plate limit and fix the tops of the first and second guard plates. After the oil is discharged through a through hole, it is collected in a collection tank. This effectively protects and collects oil leaking from the diesel engine during operation, preventing direct contact between the oil and workers, facilitating subsequent oil collection and cleaning, and improving practicality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0019] Please see Figure 1-4 A special testing device for diesel engines includes a workbench 1. Two first guard plates 2 are symmetrically and rotatably mounted on the top of the workbench 1 via two second hinges 5. Two second guard plates 3 are symmetrically and rotatably mounted on the top of the workbench 1 via two first hinges 4. A top plate 6 is attached to the top of each first guard plate 2 and each second guard plate 3. Multiple first limiting plates 7 are symmetrically and fixedly mounted on the bottom of the top plate 6. Each first limiting plate 7 is attached to the outer side wall of each first guard plate 2 and each second guard plate 3. Multiple through holes 9 are opened in the middle area of ​​the workbench 1. Multiple fixing mechanisms are provided on the top of the workbench 1.

[0020] Please see Figure 1-4 The fixing mechanism includes a fixing post 11, which passes through one of the through holes 9. Two fixing screws 10 are symmetrically screwed onto the fixing post 11, and the two fixing screws 10 are tightly fitted to the top and bottom of the workbench 1, respectively. Multiple second limiting plates 12 are symmetrically fixedly installed on the top of the workbench 1. Each second limiting plate 12 is fitted to the outer wall of each first guard plate 2 and second guard plate 3. By installing the second limiting plates 12, the rotation angle of the outer wall of each first guard plate 2 and each second guard plate 3 is limited. A first handle 13 is fixedly installed on the top of the top plate 6, facilitating the removal of the top plate 6. It should also be noted that an observation window 14 is provided on the outer wall of each first guard plate 2, allowing the user to observe the working status of the diesel engine fixed inside the workbench 1. A collection trough 8 is provided on the workbench 1. A door 15 is provided on the outer wall of the collection tank 8, and a second handle 16 is installed on the door 15. The installation of the door 15 and the second handle 16 facilitates the removal of the oil collected in the collection tank 8 and facilitates the rotation of the fixed column 11 at the bottom of the workbench 1. Multiple support columns are fixedly installed around the bottom of the collection tank 8 to facilitate the support of the device. This special testing equipment for diesel engines uses the first guard plate 2 and the second guard plate 3 to isolate the oil in the diesel engine. The top plate 6 and the first limiting plate 7 limit and fix the top of the first guard plate 2 and the second guard plate 3. After the oil is discharged through the through hole 9, it is collected in the collection tank 8. This effectively protects and collects the oil that leaks when the diesel engine is working, avoids direct contact between the oil and the workers, facilitates the collection and cleaning of the oil later, and improves its practicality.

[0021] In summary, when using this dedicated testing equipment for diesel engines, the diesel engine is moved to the top of the workbench 1 and fixed by multiple fixing posts 11. By rotating the two fixing screws 10 on each fixing post 11, the fixing screws 10 are tightly fitted to the top and bottom of the workbench 1, thus completing the fixing of the fixing posts 11. The first guard plate 2 and the second guard plate 3 are rotated by the second hinge 5 and the first hinge 4 respectively. The rotation angle of the second guard plate 3 and the first hinge 4 is limited by the second limiting plate 12. The first limiting plate 7 at the bottom of the top plate 6 is tightly fitted to the outer wall of the first guard plate 2 and the second guard plate 3, thus completing the fixing and limiting of the first guard plate 2 and the second guard plate 3. The working status of the diesel engine is observed through the observation window 14. When the diesel engine leaks oil, the oil is moved to the inside of the collection tank 8 through the through hole 9 for collection.
