Product description
A professional testing device specially designed for testing the spinning handles (rotating handles) of doors and Windows, used to evaluate the mechanical performance, operational comfort and fatigue life of the handle products under long-term repeated use conditions. This equipment conducts systematic tests on the durability, operating torque and structural reliability of the handle by simulating the real scene of repeated rotation operations of the human hand.

Test method
4.4.4 Repeated opening and closing
After being repeatedly opened and closed 15,000 times, the change in the spinning position should not exceed 0.5mm.
5.5.4 Repeated opening and closing
Install the spinning handle and the mating pad block on the test simulation window according to the actual usage state when the window sash is closed (see Figure 3), and rotate the axis of the handle
Keep applying a force F of 70+8N along the opening direction of the window sash on the line. Measure and record the initial distance L1' between the frame and sash at the handle locking point at 250 times per hour ~
Operate the handle at a frequency of 275 times per hour for 15,000 repeated opening and closing operations. Check the damage of the handle every 5,000 times, measure and record the repeated opening and closing
The distance l between the frame and the sash at the handle lock. The change in distance Δ l' between the front and rear frames and sashes of the handle lock position when repeatedly opening and closing is calculated according to Equation (2).
