Fengnan Office Chair Strength Tester (Translation Reference)

Currently, no device directly named 'Fengnan Office Chair Strength Tester' has been found, but there are several functionally similar office chair strength testing devices available for reference:

Office Chair Strength Testing Machine: This device is primarily used to test the vertical strength of office chair armrests, horizontal strength of armrests, and the strength of the chair backrest. It utilizes a PLC controller paired with an LCD touch screen for parameter setting, allowing precise configuration of test force values, pressure holding, and cycle times. When the specified force value is reached, the device automatically starts timing and returns to its original position after timing is complete. Its design adheres to multiple clauses in BIFMAX5.1 - 2011. In terms of technical parameters, it has a capacity of 0 - 500kg, a time setting range of 0 - 99S, and an approximate machine size of (L×W×H) 1500×1400×1800mm. The testing accessories include one auxiliary testing platform for chair armrest strength testing, one set of vertical armrest strength testing fixtures, and one set of backrest strength testing fixtures.

Backrest and Armrest Impact Testing Machine: Model LT - JJ21, it complies with QB/T 2280 - 2007, GB/T 10357.2 - 2013, and GB/T 10357.3 - 2013 standards. It is equipped with a 6.5kg impactor, with an impact height range of 150mm to 1200mm. It uses an adjustable air source with a pressure of ≥0.6Mpa, a flow rate of ≥800L/min, and which has been filtered and dried. This device has multiple functions, capable of conducting backrest impact tests, armrest impact tests, chair leg strength tests, and footrest durability tests. The main technical parameters include two sets of pneumatic actuators that can be installed at a 10-degree adjustable tilt or fixed vertically, and another two sets of horizontally installed actuators for chair leg horizontal thrust tests, with an adjustment range from a minimum of 20mm to a maximum of 250mm, and a maximum thrust of 60kg; the armrest height adjustment range is 550mm - 950mm; the thrust and pressure holding time are adjustable; the maximum sample width is 1000mm, etc.

Office Chair Impact Comprehensive Testing Machine: Used for backrest strength and fatigue testing of seats, as well as chair impact tests. The impact speed can be adjusted within the range of 5 - 40 impacts per minute or within a specified range. The power supply is 1∮, ac220v, 50hz, 5av, with a weight of 290kg, and it can be customized. The control method is a touch screen + PLC, with a machine size of 25009001700mm, a maximum output stroke of 600mm, a testing platform width of 1000mm, a cylinder output force greater than 150 kgf, a vertical pressing plate diameter of ￠127±13 mm, and the brand is Litop.

Office Chair Five-Claw Compression Testing Machine: Mainly used to test the compression strength of the five-claw support of office chairs. It assesses the pressure resistance strength by applying vertical pressure to the five-claw through computer control, with the testing program typically involving slow loading to a specific force value (e.g., 11120 Newtons) and holding it for a period of time. It is driven by a servo motor, equipped with a high-precision load cell, and can automatically generate test curves such as force-time curves. There are various models available, such as BLD - 1608 and GX - 2332. The design standard is the American BIFMA standard, with technical parameters including a maximum stroke of 1000mm, an effective width of 700mm, and a pressing plate diameter of 700mm, etc.
