Office Chair Testing Bench
The office chair testing bench is a professional device used to evaluate the quality and durability of office chairs, primarily conducting tests in accordance with national standards. Common types include office chair testing instruments and seat reciprocating impact testers.
The office chair testing instrument is one of the core devices, primarily used to assess the fatigue resistance of the office chair backrest when reclining. Its working principle involves fixing the chair wheels and applying an iron disc load on the seat surface to simulate human weight. Simultaneously, it applies an adjustable-angle (15 degrees to 90 degrees) and controllable-frequency (10 to 30 times per minute) load to the backrest, with a test cycle of up to 120,000 times. The backrest load uses a canvas bag filled with steel balls to ensure uniform and adjustable load distribution. The instrument is equipped with an LED counter, a PLC control system, and a touchscreen operation interface, enabling real-time monitoring of the test status. It also features photoelectric sensing functionality, automatically stopping the machine if the test sample falls, ensuring test safety. In terms of technical parameters, the force application height ranges from 406mm to 456mm, the machine dimensions are 1400ร1200ร2500mm, and the power supply specification is AC220V/50Hz, suitable for most laboratory environments.
The seat reciprocating impact tester, on the other hand, accurately measures the true durability of the chair by simulating daily usage scenarios. Its testing method involves using a 57KG sandbag to simulate human weight, continuously impacting the seat from a height of 30mm. Through repeated impacts, it tests the fatigue resistance of the seat material and structural stability. This device is simple to operate and provides intuitive results, making it an important tool for evaluating seat durability.
Additionally, Dongguan Lituo Testing Instrument Co., Ltd., as a one-stop manufacturer of furniture testing equipment, offers a variety of office chair testing devices, such as the LT-JJ10-A Office Furniture Mechanical Performance Comprehensive Tester, the LT-JJ02-C Office Chair Backrest Repeated Tester (Rear Pull Type), and the LT-JJ03-B Office Chair Repeated Impact Tester, meeting different testing needs. These devices are all designed in accordance with standards such as GB/T10357 and QB/T2280-2007, ensuring the authority and reliability of the test results.
