Description

TECHNICAL FIELD

[0001] The application belongs to the field of trampoline detection devices, and particularly relates to a test device. BACKGROUND

[0002] A trampoline usually needs to be detected to meet the standards before being put into use, and after being put into use, parts of the trampoline also need to be detected regularly to ensure that the trampoline is used normally. The trampoline needs to be detected for many parts, including an elastic surface, a protective fence arranged around the elastic surface, a protective pad and the like. The protective fence needs to be subjected to impact detection, according to the standards, an impact object needs to be hung in front of the center position of the protective fence, and the impact object is deflected to have an impact force to impact the protective fence, and the performance of the protective fence is determined by detecting the angle change of the protective fence before and after the impact. In order to meet the test standards, the impact object needs to have sufficient impact force, and in the prior art, the impact force of the impact object is increased by increasing the deflection angle of the impact object. The detection of the elastic surface needs to press down the center position of the elastic surface to ensure the function of the elastic surface. The protective pad also needs to be subjected to ballast test and impact test, which leads to a complicated detection process of the trampoline, the trampoline needs to be transported back and forth between different institutions, and the detection efficiency is low. Moreover, the fixed position of the detection device and the detection method have requirements for the site, for example, a top building for hanging the impact object and a mounting space of the corresponding mechanism are needed, so that the detection process of the trampoline is more complicated.

[0003] In a prior art, the detection of the elastic surface and the detection of the protective fence are arranged inside the trampoline, and the detection of the protective fence must impact the protective fence from inside the trampoline, the impact object moves away from the center position of the protective fence, and the elastic surface needs to be detected at the center position, which leads to interference of the detection of the elastic surface in the deflection process of the impact object. In order to avoid the influence on the detection of the elastic surface, the deflection angle of the impact object needs to be reduced, and thus the impact force is reduced, which affects the detection effect of the protective fence and does not meet the detection standards.
