DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-4The utility model provides a technical solution, a testing machine, including a box body 1, a first connecting plate 2 is fixedly connected to the lower end of the box body 1, and the lower end of the first connecting plate 2 is fixedly connected to the bottom of the box body 1, a second connecting plate 3 is slidably connected to the first connecting plate 2, first telescopic springs 4 are symmetrically fixedly connected to both ends of the second connecting plate 3, the first telescopic spring 4 is also fixedly connected to the first connecting plate 2, one end of the second connecting plate 3 is fixedly connected to a first rotating shaft 5, one of the first rotating shafts 5 is fixedly connected to a driving plate 6, and one end of the driving plate 6 away from the second connecting plate 3 is fixedly connected to a first connecting shaft 7, a connecting rod 8 is fixedly connected to the first connecting shaft 7, and another first rotating shaft 5 is fixedly connected to the other end of the connecting rod 8.

[0017] Furthermore, the second rotating shafts 9 are fixedly connected at both ends of the box body 1, and the lifting plates 10 are fixedly connected between the second rotating shafts 9. The driving motor 15 drives the second rotating shafts 9 to rotate, and the lifting plates 10 connected thereto are driven to rise and fall.

[0018] Furthermore, one end of the lifting plate 10 away from the first connecting plate 2 is fixedly connected to a second connecting shaft 11, and the upper end of the second connecting shaft 11 is fixedly connected to a second telescopic spring 12. One end of the second connecting shaft 11 is connected to the lifting plate 10 and the other end is connected to the second telescopic spring 12. When the lifting plate 10 descends, the second telescopic spring 12 provides traction to the lifting plate 10 through the second connecting shaft 11.

[0019] Furthermore, one end of the second telescopic spring 12 away from the second connecting shaft 11 is fixedly connected to a resist column 13, and the upper end of the resist column 13 is fixedly connected to a storage slot 14. When the lifting plate 10 rises upward, the second connecting shaft 11 and the second telescopic spring 12 move upward, causing the resist column 13 to hit the storage slot 14 upward.

[0021] Specifically, when using the utility model, some liquid is placed in the lunch box required for the experiment and put into the storage groove 14, the driving plate 6 rotates, and the two second connecting plates 3 are driven to shake through the connecting rod 8. The second connecting plates 3 shake more violently due to the elastic force of the first telescopic springs 4 at both ends. At this time, the storage groove 14 connected to the upper ends of the two second connecting plates 3 changes back to produce violent back and forth shaking, and the driving motor 15 is started. The driving motor 15 drives the second rotating shaft 9 to rotate, and the lifting plate 10 connected thereto is driven to rise and fall. When the lifting plate 10 descends, the second telescopic spring 12 supplies the lifting plate 10 with a spring through the second connecting shaft 11. 0 provides traction. When the lifting plate 10 rises upward, the second connecting shaft 11 and the second telescopic spring 12 move upward, causing the support column 13 to hit the storage slot 14 upward, so that the storage slot 14 shakes up and down, thereby simulating the bumpy state of the lunch box during transportation. After running the test machine for a period of time, observe whether the liquid in the lunch box leaks out, so as to judge whether the lunch box has good sealing performance, because the movement trajectory of the lunch box following the clamping slot 14 is parabolic and omnidirectional, so that the liquid can impact at multiple angles in the lunch box, thereby better testing the sealing performance of the lunch box.
