During the impact resistance test, the impact head 6 is adsorbed on the electromagnet 5, the glass fiber board sample is placed on the placement seat 3, and by cutting off the power supply of the electromagnet 5, the impact head 6 falls off from the adsorption base, and the impact head 6 impacts the glass fiber board on the placement seat 3 after falling, thereby realizing the test of the impact resistance of the glass fiber.
[0038] Referring to Figure 1 and Figure 3 , the impact head 6 includes a main body and a plurality of counterweight pieces 8 sleeved on the main body. The counterweight pieces 8 are of an annular structure, the bottom of the impact head 6 is conical, and an impact column is arranged in the middle part. A detachable limiting plate is arranged on the impact head 6, the limiting plate limits the counterweight pieces 8, and at the same time, by disassembling the limiting plate, the number of the counterweight pieces 8 on the impact head 6 can be adjusted, thereby effectively adjusting the weight of the impact head 6, and further adjusting the impact force of the impact head 6. The impact force of the impact head 6 can be effectively adjusted, thereby improving the diversity of the test data of the testing device and the testing accuracy of the testing device.
[0039] It should be noted that the impact head 6 can be designed in different sizes. Specifically, the current size according to the national standard is: the diameter is 25 mm, and the size can be increased to a diameter of 30 mm during actual use. The impact energy of the impact head 6 under the current national standard size in the test is 120 J. After adjusting the size of the impact head 6 subsequently, the ball head mass or height can be adjusted through the formula E = mgh, so as to achieve different energy impacts.
[0040] Referring to Figure 1 and Figure 2 , the lifting mechanism 2 includes a vertical elevator 21, and the vertical elevator 21 is arranged on one side of the protection mechanism 7. The adsorption base is fixedly arranged at the output end of the vertical elevator 21. The adsorption base is horizontally arranged and is located above the placement seat 3. An electromagnet 5 is arranged on the lower surface of the adsorption base. The electromagnet 5 is electrically connected to the power supply. A magnet cooperating with the electromagnet 5 is arranged at one end of the impact head 6 away from the impact column. The adsorption base adsorbs the impact head 6 through the electromagnet 5.

[0042] It should be noted that in this embodiment, the placement seat 3 is of a U-shaped structure, and the glass fiber board is suspended on the placement seat 3 through the middle parts of the two column structures 71 at both ends of the placement seat 3. The U-shaped structure can effectively simulate the scenario where the glass fiber board is applied, and further improve the test accuracy of the test device.
[0043] Referring to Figure 1 , the protection mechanism 7 includes columns 71 vertically arranged at the four corners of the bottom plate 1, and protection nets 72 are arranged between adjacent columns 71.

Therefore, while improving the safety of the device, the service life of the device is effectively improved.

At the same time, the glass fiber board sample is placed on the placement seat 3. The electromagnet 5 is energized to adsorb the impact head 6 on the adsorption base. According to the test requirements, the weight piece 8 on the impact head 6 and the height of the impact head 6 are adjusted. After the adjustment is completed, the electromagnet 5 is powered off to realize the free release of the impact head 6, and then the glass fiber board on the placement seat 3 is impacted, thereby completing the test of the impact resistance of the glass fiber board.
[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby.
