AI Technical Summary
Existing sofa production testing equipment cannot accurately adjust the height of the sandbags, affecting the accuracy of the testing.
The system uses an electric push rod and a crossbeam. Through the cooperation of the detection ring and the limit switch, the chain is wound upward to the limit position and stops automatically. The electromagnetic chuck releases the sandbag for detection. Combined with the scale lines and locking screws, the crossbeam position is locked, allowing for flexible height adjustment.
This technology improves the convenience and accuracy of sofa impact resistance testing, simplifies the testing process, and enhances the reliability of the test.
