A high-temperature and fire-resistant hinge structure for life-saving equipment

Abstract

The invention relates to a hinge structure, in particular to a high-temperature-resistant refractory hinge structure for lifesaving equipment. When accidental disasters such as fires happen, since the temperature of surrounding areas is caused to be high due to big fires and the like, the temperature of hinges for opening or closing a door of the lifesaving equipment is also caused to be high, the hinges are easily caused to be bonded with pins and consequently the door of the lifesaving equipment cannot be normally opened or closed. Since the hinges, pins and hinge shaft sleeves of the hinge structure are made of high-temperature-resistant refractory materials with different thermal expansion coefficients and the hinge shaft sleeves are made of high-temperature-resistant refractory materials and a door of a lifesaving capsule or a lifesaving cabinet can still be normally opened or closed under the situation. Moreover, the high-temperature-resistant refractory hinge structure for the lifesaving equipment has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to a hinge structure, in particular to a high-temperature and fire-resistant hinge structure used for lifesaving equipment. Background technique [0002] At present, China's urbanization process is getting faster and faster, and high-rise buildings are increasing day by day. With the development of the city, the fire hazards of high-rise buildings are gradually exposed. For high-rise building fires, external rescue and fire-fighting operations cannot be carried out, resulting in heavy losses of personnel and property. Based on the above situation, more and more people start Configure life-saving equipment for disaster emergency response. With the promotion and use of life-saving equipment such as safety cabins, life-saving cabinets and other disaster emergency equipment, it provides a strong guarantee for our life safety and property safety. However, the existing emergency safety cabins or life-saving cabinets will , often due t...
