Description

Technical Field

[0002] In the process of furniture production, it is necessary to strictly control the quality of the finished furniture, so it is often necessary to carry out load-bearing tests on it. The load-bearing capacity of furniture such as tables and chairs directly affects its service life. In the existing patent application with application number CN202122416333.0, a furniture load-bearing detection device is proposed. However, when carrying out load-bearing detection on furniture, it can only apply pressure to the furniture for detection, which will have certain detection disadvantages. For example, some parts of furniture, such as joints, supporting structures, etc., may have a lower load-bearing capacity due to design, material or process problems. Comprehensive testing may not be able to accurately identify these weaknesses, leaving safety hazards; at the same time, comprehensive pressure testing is not targeted and cannot perform differentiated evaluations on different areas or components of furniture; and comprehensive pressure testing may not accurately reflect the load-bearing conditions of furniture in actual use. In actual use, furniture may be affected by various factors such as uneven pressure distribution, repeated lifting and lowering, shaking, etc. These factors may not be fully simulated in comprehensive testing, so they need to be improved.
