Zhuozhou Office Chair Rotation Tester
There is no specific information explicitly mentioning office chair rotation testers in Zhuozhou, but an office chair rotation tester is a professional device used to evaluate the durability of rotating office chairs. The following provides an introduction from aspects such as device functions, testing standards, core parameters, common models, and manufacturers:
Device Functions
The core function of an office chair rotation tester (such as an office chair rotation life testing machine) is to simulate the rotating actions of an office chair during long-term use. By fixing the footrest on a test disc, applying a specific load to the seat surface, and setting the number of cycles and time, it quantitatively evaluates the rotational durability and service life of the chair. This process can detect the wear and tear of the chair's rotating mechanism (such as bearings and bases) to ensure that the product meets quality requirements.
Testing Standards
The design and testing of the device must be carried out in accordance with international and domestic standards. For example, the American BIFMA standard sets clear requirements for the rotational life and structural strength of office chairs; the Chinese QB/T 2922 - 2007 standard specifies the test methods and performance indicators for rotating office chairs. These standards ensure the authority and comparability of test results.
Core Parameters
The key parameters of the tester directly affect testing accuracy, including:
- Disc Diameter: Determines the range of the rotational trajectory and needs to match the testing requirements of office chairs of different sizes;
- Test Speed: Simulates the speed of rotation during actual use and is usually adjustable to cover various scenarios;
- Seat Height: Adapts to different chair types to ensure accurate application of the load;
- Applied Load: Set according to standards to simulate the pressure exerted by human weight on the seat.
Devices produced by different manufacturers may vary in parameter ranges and adjustment accuracy.
Common Models and Manufacturers
The mainstream models on the market include LT - JJ06, KJ - 5101, and XQ - 897, among others. Manufacturers are mainly concentrated in the Dongguan area, such as Dongguan Lituo Testing Instruments Co., Ltd., Dongguan Kejian Testing Instruments Co., Ltd., and Dongguan Xingqiao Instrument Equipment Co., Ltd. These companies offer devices with various advantages in terms of functional design, automation level, and after-sales service, allowing users to choose according to their needs.
