Description

Technical Field

[0001] The utility model relates to the technical field of lifesaving equipment, in particular to an inter-floor escape device and equipment. Background Art

[0002] As people's living standards improve, more and more families begin to install and use high-power electrical appliances such as air conditioners. Despite protective measures, fires can easily occur in cases of aging or short circuits, which in turn causes greater losses. In addition to high-power electrical appliances, other indoor electrical appliances, gas stoves, etc. are also prone to fires. However, residential homes are generally not equipped with fire alarm and fire extinguishing systems. This will result in users being unable to detect and handle fires in a timely manner, indoor smoke being unable to be discharged in a timely manner, and rescuers and trapped people being unable to enter and exit the fire scene smoothly.

[0003] In addition, most residential buildings and some public buildings are only designed with one staircase, and fire partitions are often not arranged in place. This will result in the original life escape passage becoming a dangerous and fatal passage if the fire smoke enters the staircase passage in the event of a fire. The corridor is filled with thick smoke, making it impossible for residents to escape through this only life escape passage.

[0004] In view of this, this paper will propose an inter-floor escape device arranged between each floor. When a fire occurs, if it is impossible to escape through the corridor, there is a second escape life channel, which increases the chance of rescue and reduces damage. Utility Model Content

[0042] In view of the defects of the prior art, the sealing component and the alarm in the utility model cooperate with each other, so that when the first cover plate of the sealing component is opened, the alarm emits a warning sound, thereby achieving a warning and early warning function, so that nearby residents can discover the fire situation in time, take protective measures in time and flee to a safe place, avoiding inhalation of a large amount of harmful gases due to long-term failure to discover the fire; by providing a downward component that can extend toward the ground, an escape passage can be formed, which is convenient for residents to escape from the fire scene smoothly. If it is impossible to escape from the corridor, there is a second escape passage, which increases the chance of rescue and reduces damage.

[0043] See attached Figure 1 to Figure 4The present embodiment provides an inter-floor escape device, comprising: a support assembly 1, having a receiving space 11 and a first opening end; along the building height direction, part of the support assembly 1 is arranged in the floor slabs of two adjacent floors; at least one alarm device capable of emitting an alarm sound is arranged in the receiving space 11, and the alarm device comprises a starting switch 4; a sealing assembly 2, comprising a first cover plate 21, the first cover plate 21 covers the first opening end and abuts against the starting switch 4 to turn off the alarm sound of the alarm device; a descending assembly 3 arranged on the support assembly 1 can extend toward the ground to form an escape passage.

[0044] It should be noted that the sealing component 2 and the alarm in this embodiment cooperate with each other, so that when the first cover plate 21 of the sealing component 2 is opened, the alarm emits a warning sound, thereby achieving a warning and early warning function, so that nearby residents can discover the fire in time, take protective measures in time and flee to a safe place, avoiding inhalation of a large amount of harmful gases due to long-term failure to discover the fire; by setting a downward component 3 that can extend toward the ground, an escape passage can be formed, which is convenient for residents to escape from the fire scene smoothly. If the corridor cannot be escaped, there is still a second escape passage, which increases the chance of rescue and reduces damage.

[0045] It should also be noted that the inter-floor escape device in this embodiment is fixedly connected to the floor slab and is located in the floor slab between two adjacent upper and lower floors. The height of the inter-floor escape device is less than or equal to the thickness of the floor slab between two adjacent upper and lower floors.
