Description

Technical Field

[0001] The utility model relates to the technical field of escape ladders, in particular to a high-strength reinforced handrail shell dedicated to an outdoor escape ladder. Background Art

[0002] An escape ladder, also known as a fire escape ladder, is a building facility that serves as an escape route in case of fire. It is required by fire laws in many countries and is included in the inspection items of building fire licenses. An escape ladder is usually different from the main daily stairs and is set up as a second passage. Many early buildings in the United States are set up on the outside of the building in the form of welded iron frames. On the one hand, it will not constitute a burden on the building structure. On the other hand, it will not occupy indoor space if it is set outdoors. Third, escaping from a fire outside can avoid the chimney effect.

[0003] For example, a portable safety escape ladder with application number 202021773420.0 can be unfolded by pulling the bottom plate provided under the telescopic bracket, and the back plate can be leaned against a wall or a fixed object, making the entire device more stable, the safety performance more stable, reducing unnecessary personal injuries, and being simple and convenient to operate. The locking device has a simple structure and is easy to install in the telescopic bracket, which reduces the manufacturing and use costs of the locking device, and is convenient for users to operate. At the same time, the length of the ladder equipped with the locking device can be reduced when it is folded, and the placement area is reduced, so it will not take up more space. However, the handrail of the safety escape ladder is difficult to assist in escape. For vulnerable groups, going down the stairs is relatively slow, which can easily delay precious escape time.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-strength reinforced handrail shell for outdoor escape ladder is proposed. Utility Model Content
