[0002] Explosion-proof equipment refers to the equipment specially designed for use in the environment with flammable, explosive gas, vapor or dust, which can prevent the leakage of spark, heat or flame when failure occurs, thereby avoiding the initiation of explosion or fire. Such equipment is usually applied in high-risk environments such as petroleum chemical industry, coal mine, pharmaceutical, power, aviation, etc.

[0003] After the production of explosion-proof equipment, the impact resistance of the explosion-proof equipment usually needs to be tested to meet the use standard. However, due to the different types, design standards and use environments of the equipment, the strength standards of the impact resistance are also different. Therefore, when testing the impact resistance of the explosion-proof equipment, the impact force of the test device needs to be adjusted. However, the existing part of the impact force test device changes the size of the impact force by adjusting the height of the impact hammer, which leads to the smaller test range and poorer adaptability of the part of the impact force test device. Therefore, we propose an impact resistance test device for explosion-proof equipment. UTILITY MODEL CONTENT
