Description

Hanging air cushion for high-rise fire escape

Technical Field

The invention relates to a suspension air cushion for high-rise fire escape, and relates to the field of escape equipment.

Background

As the number of high-rise buildings in the current society is increased, high-rise building fire escape equipment becomes a necessary project, but most of the current high-rise escape equipment directly jumps to the downstairs or escapes to the downstairs along ropes.

But the floor above the fire floor needs to escape, and the escape can be carried out only by escaping to the floor below the fire floor. This has been done in order to allow people above the fire to escape the fire, i.e. to reach floors below the fire.

Disclosure of Invention

In view of the defects of the prior art, the invention aims to provide the suspension air cushion for high-rise fire escape, which has a simple structure, is convenient and efficient.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a high-rise conflagration flees and uses suspension air cushion, includes the housing that is used for installing edge under the outer wall window, and the uncovered of housing is down, and it has the air cushion that expandes after being used for aerifing to wind on the inside spool of housing, is connected with the gas tube on the air cushion and its four corners position is connected with the fire rope, and the gas tube all winds on the spool with the fire rope, and wherein fire rope tip and spool fixed connection, gas tube tip fixed connection are in housing top opening.

Preferably, the periphery of the air cushion which is unfolded after inflation is provided with a surrounding baffle, and the surrounding baffle is communicated with the inner cavity of the air cushion to perform synchronous inflation and expansion.

Preferably, the air cushion and the inflation tube are both made of fireproof materials.

Preferably, the fire-retardant rope is a steel wire rope.

Preferably, a gear is coaxially and fixedly installed at one end of the reel, a pin hole is formed in the top of the housing, an opening pin is inserted into the pin hole, and the bottom of the opening pin is clamped into a top tooth of the gear.

Preferably, the side of the window of the outer wall is provided with a fire extinguisher for inflating the inflation tube.

Preferably, a torsional spring is coaxially arranged at the joint of the end part of the reel and the housing, and the torsional spring is in a torsional state when the air cushion is wound on the reel.

Compared with the prior art, the invention has the following beneficial effects: the high-rise fire escape suspension air cushion is simple in structure, and is mounted on the lower edge of a window in the same vertical direction of each floor during use. When the escape device is used, the air cushion, the fireproof rope and the inflation pipe are released from the scroll, the inflation pipe inflates and expands the air cushion to form an escape suspension air cushion, an escape platform taking the inflation cushion as a bottom is formed below the escape suspension air cushion, and an escape person only needs to jump onto the platform and then crosses over a fire floor; if the floor that jumps off also has the condition of a fire, can't get into, then open this layer's suspension air cushion also, need not get into the window, can accomplish to open externally, then jump to next suspension air cushion in.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Description

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1-5, a high-rise fire escape suspension air cushion comprises a housing 1 installed at the lower edge of an outer wall window, wherein an opening of the housing faces downwards, an air cushion 3 which is used for being inflated and then unfolded is wound on a scroll 2 inside the housing, an inflation tube 4 is connected to the air cushion, a fireproof rope 5 is connected to the position of the four corners of the inflation tube, the inflation tube and the fireproof rope are wound on the scroll, the end part of the fireproof rope is fixedly connected with the scroll, and the end part of the inflation tube is fixedly connected to a through opening at the top of the housing.

In the embodiment of the invention, the periphery of the air cushion which is unfolded after being inflated is provided with the surrounding baffle 6, and the surrounding baffle is communicated with the inner cavity of the air cushion to be inflated and expanded synchronously, which is similar to the inflating structure of an indoor swimming pool.

In the embodiment of the invention, the air cushion and the inflation tube are both made of fireproof materials.

In the embodiment of the present invention, the fire-resistant rope is a steel wire rope.

In the embodiment of the invention, a gear 7 is coaxially and fixedly arranged at one end part of the scroll, a pin hole is arranged at the top part of the housing, an opening pin 8 is inserted in the pin hole, and the bottom of the opening pin is clamped in the top teeth of the gear.

In the embodiment of the present invention, a fire extinguisher 9 for inflating the gas tube is provided to a side of the window of the exterior wall. The outlet of the fire extinguisher is connected with the inflation tube, the using steps of the fire extinguisher are the same as the prior art, and the air cushion is inflated by carbon dioxide in the fire extinguisher, so that the air cushion is cooler and resists high temperature.

In the embodiment of the invention, the joint of the end part of the scroll and the housing is coaxially provided with the torsion spring, and the torsion spring is in a torsional state when the air cushion is wound on the scroll. After the opening pin is pulled out, the reel rotates under the reset action of the torsion spring to release the air cushion, the fireproof rope and the inflation tube from the reel.

The high-rise fire escape suspension air cushion is simple in structure, and is mounted on the lower edge of a window in the same vertical direction of each floor during use. When the escape device is used, the air cushion, the fireproof rope and the inflation pipe are released from the scroll, the inflation pipe inflates and expands the air cushion to form an escape suspension air cushion, an escape platform taking the inflation cushion as a bottom is formed below the escape suspension air cushion, and an escape person only needs to jump onto the platform and then crosses over a fire floor; if the floor that jumps off also has the condition of a fire, can't get into, then open this layer's suspension air cushion also, need not get into the window, can accomplish to open externally, then jump to next suspension air cushion in. The escape personnel can escape by crossing the fire layer without jumping to a too high height.

The present invention is not limited to the above-mentioned preferred embodiments, and various other types of suspension cushions for high-rise fire escape can be obtained by anyone who can use the present invention. All equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
