[0035] This application can be used in the field of testing, or in other fields applicable to this application.

[0036] Example 2

[0037] refer to Figures 1-6 Improvements based on Example 1:

[0038] A device for detecting bending resistance, which is applied in the field of testing;

[0039] In order to collect the waste material after the board is crushed, a collection component is required. The collection component includes two guide grooves 13, which are fixedly connected to the two bases 1 on the side close to each other. Two guide blocks 14 are slidably connected to the inner walls of the two guide grooves 13, and a waste box 2 is fixedly provided between the two guide blocks 14.

[0040] To display the measured bending strength value, a display component is required, which includes a display screen 11, which is fixedly connected to one side of the fixed box 9.

[0041] To adjust the position of the pressure sensor 18, a push-pull assembly is required. The push-pull assembly includes an electric push rod 7, and the telescopic end of the electric push rod 7 is fixedly connected to a first fixing block 6. The first fixing block 6 is fixedly connected to the outer wall of the fixing rod 5.

[0042] To position and fix the object 12 being measured, the bottom of the positioning plate 3 is also provided with a positioning component. The positioning component includes two limiting blocks 26, which are fixedly connected to one side of the positioning plate 3. Two second fixing blocks 19 are fixedly connected between the two limiting blocks 26 by positioning screws 20. The same second central shaft 24 is fixedly provided between the two second fixing blocks 19. The outer wall of the second central shaft 24 is slidably fitted with a positioning bottom block 22 for pressing the plate. The bottom of the positioning bottom block 22 is fixedly fitted with a positioning block 21 for guiding and positioning the plate. Sliding blocks 25 are fixedly provided on both sides of the positioning bottom block 22. The sliding blocks 25 are slidably disposed in the limiting blocks 26. The outer wall of the second central shaft 24 is fitted with a second spring 23. The two ends of the second spring 23 are respectively fixedly connected to one of the second fixing blocks 19 and the side of the positioning bottom block 22 that are close to each other.

[0043] To drive the pressure sensor 18 to move up and down, a lifting assembly is required. The lifting assembly includes a hydraulic rod 8, which is fixedly connected to the bottom of the fixed box 9. The output end of the hydraulic rod 8 is fixedly connected to a first central shaft 17. The first central shaft 17 passes through the slider 27 and is slidably connected to the slider 27. A first spring 16 is sleeved on the outer wall of the first central shaft 17. A rubber sleeve 15 is sleeved on the outer side of the first central shaft 17. The rubber sleeve 15 is fixedly connected to the hydraulic rod 8 and the slider 27. The rubber sleeve 15 is sleeved on the outer side of the first spring 16.

[0044] In this application, the working principle is as follows: First, the positioning base block 22 is adjusted. During the adjustment, the positioning screw 20 is rotated to release the limit on the second fixing block 19. Then, the positioning base block 22 is moved to a suitable position, specifically one to two centimeters larger than the object being measured 12. The positioning screw 20 is rotated again to limit the positioning of the second fixing block 19.

[0045] Then adjust the waste bin 2. During the adjustment, clean the inside of the waste bin 2 and move the waste bin 2 to a suitable position, specifically directly below the pressure sensor 18.

[0046] Then turn on the pressure sensor 18 and the distance sensor 29, and keep them on.

[0047] When the test object 12 is first tested, it is placed between the two bases 1. Then, the hydraulic rod 8 is activated to lower the positioning plate 3. The positioning plate 3, along with the positioning blocks 21 and the positioning base 22, descends until the positioning blocks 21 and the positioning base 22 contact the test object 12. Subsequently, the four positioning blocks 21 slide along the second central axis 24 against the test object 12 until the top of the test object 12 is pressed tightly by the positioning base 22. At this point, the test object 12 is pressed and fixed directly below the pressure sensor 18. Then, the hydraulic rod 8 continues to operate, and the first central axis 17 drives... When the pressure sensor 18 contacts the object 12 being measured, the first spring 16 is compressed, and the object 12 is in a bent state. Since the distance sensor 29 is working in real time, the degree of bending is recorded in real time. The bending data is displayed on the display screen 11. After the test is completed, the hydraulic rod 8 is used to reset the first spring 16, the first central shaft 17, the pressure sensor 18, and the distance sensor 29. The first spring 16 pushes the pressure sensor 18 to reset, and then the electric push rod 7 is activated to move the fixed box 9 to the next test point to continue the test. This cycle repeats.

[0048] However, as is well known to those skilled in the art, the working principles and wiring methods of the ranging sensor 29, pressure sensor 18 and display screen 11 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
