Description

Technical Field

[0001] The invention belongs to the technical field of compression resistance detection, in particular to a device for detecting the compression resistance of a scientific research filing cabinet. Background Art

[0002] The main function of the compressive performance testing device for scientific research filing cabinets is to evaluate and verify the bearing capacity and structural strength of filing cabinets when subjected to pressure. By simulating actual use or stacking pressure, the filing cabinets are tested to ensure that they have sufficient compressive performance and meet safety and usage standards. The maximum bearing capacity of the filing cabinet under increasing pressure is determined to ensure that it will not be deformed, damaged or collapsed due to excessive pressure in actual use. Testing the stability and compressive performance of filing cabinets in stacked or fully loaded states helps prevent accidents caused by weak structures. Through compressive performance testing, the reliability of the file storage environment is guaranteed, deformation, cracks or even collapse during stacking or use is avoided, and the integrity of archival materials is protected. It can assist manufacturers or management departments in complying with the relevant industry standards for testing the compressive performance of filing cabinets.

After the end enters the positioning hole 12, the position of the pressure block 11 can be positioned, and then when the pressure plate 8 moves, the pressure block 11 will be driven to move, and the pressure block 11 will first contact the top of the filing cabinet. At this time, the pressure begins to be transmitted to the pressure sensor 7, and the pressure block 11 can be used to perform pressure detection on the local position of the top of the filing cabinet, thereby improving the flexibility of the detection device for the pressure resistance of the scientific research filing cabinet, and facilitating detection according to actual needs. During the detection period, if the surface of the scientific research filing cabinet is damaged, the debris generated will fall onto the support frame 9, and the support frame 9 will cause the debris to fall into the storage box 40, and the storage box 40 will store the debris. When the debris is cleared, pulling the handle 43 to move will drive the storage box 40 to move, and the storage box 40 will be moved. The movement of the slider 41 and the guide groove 42 will make the storage box 40 move smoothly, and the storage box 40 can be moved to the outside to remove the stored debris, which can effectively ensure the cleanliness of the detection environment without frequent manual cleaning. The fan 39 is operated to generate wind flow, and the wind will flow into the inside of the rotary joint 33 through the pipeline, and the wind will flow into the inside of the cylinder 34 through the rotary joint 33, and the wind will flow downward through the nozzle 35. The wind will flow to the top of the scientific research file cabinet, and then the top of the scientific research file cabinet can be cleaned. Dust and impurities may affect the contact effect between the pressure plate 8 and the file cabinet, resulting in inaccurate pressure measurement. After cleaning, it can be ensured that the pressure sensor 7 is in good contact with the surface of the file cabinet, and the real pressure value is obtained.Ensures the accuracy of detection.
