Abstract

A spring tensile fatigue test device is disclosed. The spring tensile fatigue test device comprises a support, a sliding bar, a first connecting bar, a circular disc and a supporting bar. The support is U-shaped, and is connected to the sliding bar in a sliding manner. Both ends of each spring to be tested are respectively connected to the support and the sliding bar. The first end of the first connecting bar is fixedly connected to the sliding bar, and the second end of the first connecting bar is fixedly connected to the edge of the circular disc. The circular disc rotates around a center shaft. The supporting bar is used for supporting the circular disc. The spring tensile fatigue test device can effectively test the tensile fatigue performance of the spring to be tested, and is simple in structure, high in testing efficiency and capable of largely reducing manual labor.

Description

technical field [0001] The invention relates to the lighting field, in particular to a spring tension fatigue testing device. Background technique [0002] In the field of professional lighting, lamps and lanterns are used more and more widely, and more and more key parts are applied. In order to make the light source more suitable in the harsh vibration environment, it is generally necessary to install a shock absorber or a metal spring in the light source. However, under the existing conditions, it is impossible to effectively test the tensile fatigue properties of various springs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spring tensile fatigue testing device, which can effectively test the tensile fatigue performance of the spring to be tested. [0004] In order to solve the above technical problems, the present invention provides a spring tension fatigue testing device, which includes a bracket, a ...
