Description

Technical Field

[0001] The utility model relates to the technical field of spring testing, and more specifically, to a spring testing device for an automatic rolling curtain mechanism. Background Art

[0002] The springs used in automatic roller shutter mechanisms primarily store and release energy, helping to unfold and retract the shutters. During the manufacturing process of springs used in automatic roller shutter mechanisms, a testing device is required to perform life tests on the springs to ensure product quality. However, in actual use, there are still some shortcomings. For example, to ensure that the spring does not deflect in other directions when pressure is applied to it, the spring needs to be placed on the outside of a round rod to support it. However, springs of different sizes need to be replaced with matching round rods during testing. The steps for disassembling and assembling the round rod from the testing device are complicated and time-consuming, resulting in reduced work efficiency.

[0003] Therefore, a spring testing device for an automatic rolling shutter mechanism is proposed to solve the above problems. Utility Model Content
