Embodiment Construction

[0027] The method for testing the slow-down performance of the flip-over chair stool with the slow-down function of the present invention is carried out under the condition of an ambient temperature of 22±3°C, and includes the following steps:

[0028] The first step is to perform a slow fall performance test;

[0029] Step 1: Install the sample (ie, the chair under test) on the fixing device;

[0030] Step 2: Apply an initial torque to the chair surface of the sample, and the initial torque continues until the chair surface of the sample forms an angle of 70±5 degrees with the horizontal plane (that is, the initial torque is stopped when the chair surface forms an angle of 70±5 degrees), The chair surface is automatically and slowly dropped to the horizontal position, and the chair surface is fully opened; then another initial torque is applied to the chair surface in the horizontal position, and the initial torque continues until the chair surface of the sample forms an angle of 30...

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 drop performance of an overturning chair stool with a slow drop 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 chair stool is equipped with a hydraulic device, only an initial torque needs to be applied during use, and the seat surface can automatically and slowly fall to the horizontal position (the open state at this time), such as Figure 1 to Figure 3 As shown; again apply another initial moment to the chair surface, the chair surface automatically slowly rises to the vertical position (this time is closed). [0003] In order to test its performance, it needs to be tested for slow down performance. However, there is currently no test method for the slow-down performance of this flipping chair with a slow-down function. Summary of the invention [0004] The technical ...
