Stability testing device

Abstract

The invention provides a stability test device. The device comprises a base, a test board and a bearing table, the test board is in a flat plate shape and is arranged above the base, the test board is provided with a first end and a second end which are opposite, the first end is hinged to the base, the second end can rotate around the first end relative to the base and is supported on the base through a supporting shaft, the bearing table is arranged on the test board and provided with a bearing surface used for placing a to-be-tested product, the bearing table can rotate relative to the test table, and the rotating axis of the bearing table is perpendicular to the bearing surface. The stability test device has high stability and can meet the test requirement of a large angle range.

Description

technical field [0001] The invention relates to the field of testing, in particular to a stability testing device. Background technique [0002] Items placed on the desktop or on the ground should have sufficient stability, especially when electrical products are dumped, not only are they likely to cause damage to the product itself, but also endanger personal safety in severe cases. Therefore, a general non-fixed installed product needs to undergo a stability test before leaving the factory to ensure that it can work stably and reliably on a surface with a certain inclination. In the existing stability testing device, the test bench for placing the product is installed to the base through the support shaft connected to the center of the lower surface, and the adjustment of the inclination angle is realized through the support shaft. On the one hand, the contact area between the support shaft and the test bench is small and the pressure is strong, so the support shaft is ea...

AI Technical Summary

Problems solved by technology

On the one hand, the contact area between the support shaft and the test bench is small and the pressure is strong, which easily damages the support shaft, resulting in insufficient stability of the test bench

On the other hand, the adjustment range of the inclination angle of the test bench is limited by the gap distance between the test bench and the base. For example, when the support shaft is too short, the gap between the test bench and the base is small, which greatly limits the rotation angle of the test bench; However, the gap distance between the test bench and the base should not be too large, because it requires a correspondingly long support shaft, which is prone to deflection deformation

When the support shaft deflects, the test bench will tilt further, easily causing the product to slip off the test bench and damage the product
