Dingzhou Office Chair Backrest Tester
No targeted information directly mentioning the 'Dingzhou Office Chair Backrest Tester' has been found yet, but office chair backrest testers generally include the following types and functions:
The office chair backrest repeated tester is a relatively common type, whose main function is to test the durability of the chair back frame and the performance of the tilting mechanism. In the daily use of office chairs, the repeated tilting action of the backrest occurs frequently. This tester can simulate this usage scenario and conduct multiple repeated tests on the backrest to evaluate whether the back frame can remain stable during long-term use, whether the tilting mechanism can function properly, and whether there are any signs of loosening or damage, thereby ensuring the quality and reliability of the office chair backrest.
The office chair strength testing machine has more comprehensive functions. It can perform strength tests on the vertical and horizontal armrests as well as the chair backrest of an office chair. This device uses a PLC controller combined with an LCD touch screen for parameter setting, allowing operators to set key parameters such as test force values, pressure holding times, and cycle times according to actual needs. Its design standards refer to multiple clauses in BIFMAX5.1 - 2011. In terms of technical parameters, it has a capacity of up to 0 - 500kg and a time setting range of 0 - 99S. Additionally, it is equipped with testing accessories such as an auxiliary testing platform for chair armrest strength testing, a vertical armrest strength testing fixture, and a backrest strength testing fixture, enabling more precise strength testing of various parts of the office chair.
The office chair backrest fatigue tester focuses on simulating the action of a human body leaning backward repeatedly pulling on the backrest. It can perform a certain number of cyclic tests to detect the fatigue and wear of the backrest frame and connecting parts. During the testing process, the device can check for deformation, loosening, or breakage in the backrest frame, connecting chassis, and screw welding positions. It is equipped with a precision control system that can accurately adjust parameters such as load size, reciprocating frequency, and number of tests, and operates fully automatically. The test data is automatically saved for subsequent analysis and evaluation. Moreover, this device has wide compatibility and can be adapted to various sample styles. It can also be used in conjunction with a complete set of office chair mechanical testing equipment.
