Safety helmet water absorption performance test apparatus

Abstract

The invention relates to a safety helmet water absorption performance test apparatus, which comprises a box and a weighing mechanism, wherein a first installation part and a second installation part are arranged in the box, an atomizing spraying mechanism is arranged in the box, the weighing mechanism is provided with a water cup, the water cup receives water flowing from a safety helmet, the weight of the water cup is real-timely weighed by the weighing mechanism, and the second installation part is provided with a straingauge type transducer for real timely weighing the weight of the safetyhelmet. According to the present invention, the mist-like water droplets are sprayed onto the safety helmet by the atomizing spraying mechanism to disperse the water droplets around the safety helmet,the water flowing from the safety helmet is received by the water cup, the weight of the water cup is real-timely weighted by the weighing mechanism, the weight of the safety helmet is real-timely measured by the straingauge type transducer, and the water absorption performance of the safety helmet is analyzed according to the weight change of the safety helmet and the weight change of the waterin the water cup, such that the automated setting of the test is achieved, the test efficiency is improved, and the accuracy of the test is high.

Description

technical field [0001] The invention relates to a device for testing the water absorption performance of a helmet. Background technique [0002] The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head. It is a protective product to prevent impact objects from hurting the head. When the worker's head is impacted by falling objects, the helmet shell The cap lining decomposes the impact force to the entire area of ​​the skull in an instant, and then absorbs most of the impact force by using the elastic deformation, plastic deformation and allowable structural damage of the buffer structure of each part of the helmet, so that the final impact on the head The impact force is reduced to below 4900N, so as to protect the head of the operator, and the human body is prone to sweat during the wearing of the helmet, so it is necessary to set good water absorption performance in the helmet during the design and production process, w...
