Test method for slow-down performance of reversible chairs and stools with slow-down function

Abstract

The invention discloses a slow descent performance test method of an overturning chair having a slow descent function. The test method includes the following steps: procedure one, performing a slow drop performance test: step one, mounting a sample on a fixed device; step two, applying initial torque to a chair surface of the sample, and enabling the chair surface to slowly drop to a horizontal position, so that the chair surface is fully opened; then applying another initial torque to the chair surface located in the horizontal position, and enabling the chair surface to automatically and slowly rise to a vertical position, so that the chair surface is closed; step three, repeating the step two for more than 20000 times, then detecting the sample, detecting and recording whether the sample is normal and free from damage, measuring and recording slow drop time, if the slow drop time is not less than 3 seconds, and a hydraulic device has no oil leakage phenomenon, an included angle of the chair surface and a horizontal plane is not smaller than 90 degrees after the chair surface is closed, and the chair surface still remains non-dropping, executing procedure two; and procedure two, performing a strong pressure test. The slow descent performance test method in the invention can realize a slow descent performance test of the overturning chair having the slow descent function.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the slow-down performance of an overturned stool with a slow-down function. Background technique [0002] In the bathroom, a flip stool or chair with a slow-down function is generally used. Since the seat surface of this kind of chair stool is equipped with a hydraulic device, only an initial torque is applied during use, and the seat surface can automatically and slowly fall to a horizontal position (at this time, it is in an open state), such as Figure 1 to Figure 3 As shown; another initial moment is applied to the seat surface again, and the seat surface automatically rises slowly to the vertical position (at this time it is in a closed state). [0003] In order to test its performance, it is necessary to test its slow-down performance. But there is still no slow-down performance test method for this overturning chair stool with slow-down function at present. Contents of...
