[0002] To ensure the stable operation of internal combustion engines, it is necessary to conduct precise tests on them in various aspects before and after manufacturing and use. For example, patent document CN210166150U discloses a testing device for automotive internal combustion engines. This device can create a good air circulation environment through auxiliary devices, thereby effectively improving safety. While creating air circulation, it can also provide good lighting function, effectively facilitate fuel pressure testing, and is easy to use.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses an internal combustion engine testing device with a layered testing module.

[0025] This utility model provides, for example Figure 1-3 The internal combustion engine testing equipment shown includes a testing box 1 and a support plate 2 fixedly disposed on the side of the testing box 1. The side of the support plate 2 is provided with a moving groove. Multiple spaced support tubes 3 are fixedly passed through the moving groove and the side of the testing box 1. Push rods 4 are slidably passed through the inside of the support tubes 3. Detection sensors 5 are fixedly disposed at the ends of the push rods 4. The multiple detection sensors 5 are of different types. A first spring 6 is sleeved on the rod wall of the push rod 4. The two ends of the first spring 6 are fixedly connected to the push rod 4 and the support tube 3, respectively.

[0026] A support rod 7 is fixedly inserted through the upper end of the moving groove. A push plate 8 is rotatably sleeved on the wall of the support rod 7. A fixed plate 9 is fixedly inserted at the bottom of the push plate 8. A push frame 10 is rotatably inserted through the fixed plate 9. A through hole is opened inside the fixed plate 9 to cooperate with the rotation of the push frame 10. A rotating component is provided at the lower end of the push frame 10, and a push block 11 is provided through the rotating component. Guide grooves are opened on both sides of the inner wall of the moving groove. Guide blocks 17 are fixedly installed on both sides of the push block 11. The guide blocks 17 are slidably disposed in the guide groove. The push block 11 is in contact with the end of the push rod 4. A guide slope is opened on the side of the push block 11 and the push rod 4 that are close to each other.

[0027] In order to fix the position of the push plate after the push block is fixed, and to ensure stable contact between the push block and the push rod to determine the detection position of the detection sensor, such as... Figure 1As shown, the push frame 10 is arranged in a ring shape. The rotating assembly includes a fixed tube 12, which is fixedly connected to the push block 11. The lower end of the push frame 10 is rotatably disposed in the fixed tube 12. The end of the support rod 7 is fixedly provided with a rotating plate 13. The outer wall of the rotating plate 13 is provided with a plurality of axially evenly distributed positioning grooves. The outer wall of the push plate 8 is fixedly provided with a mounting plate 14. A positioning rod 15 is slidably inserted inside the mounting plate 14. The end of the positioning rod 15 is inserted into the positioning groove. The rod wall of the positioning rod 15 is sleeved with a second spring 16. The two ends of the second spring 16 are fixedly connected to the mounting plate 14 and the positioning rod 15, respectively.

[0028] Working principle: When using this testing equipment, first place the internal combustion engine in the testing area, rotate the push plate 8 according to the testing requirements, the push plate 8 rotates around the support rod 7, and the mounting plate 14 moves accordingly. At this time, the positioning rod 15 can be pulled, so that the positioning rod 15 is disengaged from the positioning groove of the rotating plate 13 under the action of the second spring 16. Then rotate the push plate 8 and select the corresponding detection sensor 5 according to the testing item. After the push plate 8 rotates to the appropriate angle, the positioning rod 15 is re-inserted into the corresponding positioning groove and fixed. At this time, the push frame 10 drives the push block 11 to move, and the guide slope of the push block 11 contacts the guide slope of the push rod 4.

[0029] When the push plate 8 drives the push frame 10 to rotate, the push block 11 slides in the guide groove, squeezing the push rod 4 to overcome the elastic force of the first spring 6, causing the push rod 4 to drive the detection sensor 5 to extend out of the support tube 3 and be aligned with the part of the internal combustion engine to be tested. After the test is completed, the push frame 10 is released, the first spring 6 resets and drives the push rod 4 and the detection sensor 5 to retract. The push plate 8 can be rotated to select other detection sensors 5, realizing layered multi-detection and improving detection efficiency.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
