IV. Operating Procedures for Office Chair Back Test Machine;
Simulate the action of a human body leaning backward while sitting on a chair, and test the performance of the chair backrest.
V. Structure of the office chair back test machine:
This equipment is a multi-functional testing device. You can choose the cylinder pressure regulating valve and adjust it to a certain pressure to determine the output force stroke.
The loading pad is attached to the back of the chair and is connected to the cylinder through an adjustable joint. After the cylinder is unloaded, the chair back naturally returns to its original state relying on its own elasticity.
The precision manual pressure regulating valve ensures the stability and reliability of the cylinder's output force.
The test sample is fixed by an L-shaped baffle and an L-shaped retaining plate. The sample is kept tightly pressed by manual screws.
Adjustable speed.
