Abstract

The invention discloses a spring strength fatigue test device which includes a force-applying device, a movable plate on which a plurality of springs are arranged, a first pressing plate and a force displaying instrument. The movable plate is disposed in a force-applying direction of the force-applying device. The first pressing plate is disposed at one side, which is opposite to the force-applying device, of the movable plate and is opposite to the movable plate. The force displaying instrument is fixed on one side, which is opposite to the movable plate, of the first pressing plate. A force probe is closed to the first pressing plate and is opposite to the force-applying direction of the force-applying device. The movable moves, pushed by the force-applying device, toward to the first pressing plate to enable the plurality of springs to be pressed and deformed between the movable plate and the first pressing plate and the first pressing plate to be forced and to move for acting on the force probe. The force displaying instrument displays the force sensed by the force probe. By means of the spring strength fatigue test device, a strength fatigue test of a plurality of spring samples which are in a same model can be achieved at the same time. A pressing force on the springs can be mastered very well and the spring strength fatigue test can be carried out easily and conveniently.

Description

technical field [0001] The invention relates to a strength fatigue test device, in particular to a spring strength fatigue test device which can carry out strength fatigue tests on multiple springs at the same time and has strength display. Background technique [0002] Springs, which are widely used in lamps, especially flashlight lamps, are usually used as electrodes. In the use of flashlight lamps, the spring is in a compressed state for a long time due to long-term positive pressure. In this state, if the strength of the spring is not good, it will be difficult to recover after long-term pressure, resulting in poor contact of the lamp. Therefore, the strength of the spring greatly affects the overall performance of the lamp. [0003] The strength fatigue test device is a commonly used tool for testing the strength of springs. However, the existing strength fatigue test devices are generally difficult to test a large number of springs at the same time, and it is difficul...
