Description

Technical Field

[0001] This invention belongs to the field of protective windows, and particularly relates to a protective window for emergency rescue in case of fire overflow in high-rise buildings. Background Technology

[0002] In recent years, fire accidents have occurred frequently, resulting in huge casualties and property losses. As we all know, the most dangerous factors in high-rise building fires are high-temperature smoke and fire overflow from windows, and these two are also the main causes of fire-related injuries and deaths. During fire rescue operations in high-rise building fires, people often have nowhere to hide due to the high temperature of the flames and smoke, which is extremely harmful to their bodies. In extreme cases, people inside the building (including firefighters) may fall from a great height, causing injury or death. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a safety window for fire rescue in high-rise buildings.

[0043] The supporting base plate 3 is fixed to the bottom of the fire shelter space, and a stopper 8 is installed on the left side;

[0044] Adjustable side panel 4 is detachably installed on the right side of the fire shelter space, and its inner side is connected to the wall at the window by a latch;

[0045] Inner baffle 2 is fixed to the side of the fire shelter space near the window;

[0046] The first escape ladder 5 is hinged to the bottom right side of the fire-avoidance space;

[0047] The second escape ladder 6 is hinged to the top of the outer side of the first escape ladder 5 and connected to the first escape ladder 5 by a positioning pin. Specifically, the positioning pin can be inserted into the second escape ladder 6, the first escape ladder 5, and the adjusting side plate 4 in sequence to limit the movement.

[0048] Several support components 7 are distributed at the bottom of the protective window body 1, with one end fixedly connected to the protective window body 1 and the other end fixedly connected to the wall at the window.

[0049] In the event of a fire, quickly enter the fire-safe space, pull out the pin on the adjusting side plate 4 to loosen its locking mechanism, and rotate and slide it to the left side of the supporting base plate 3 for secure installation. Then, pull out the positioning pin, allowing the first escape ladder 5 and the second escape ladder 6 to fall rapidly under gravity, facilitating a quick escape. After the first and second escape ladders 5 and 6 have stabilized, quickly leave the fire scene using the escape ladders. The adjusting side plate 4 on the right side of the escape window is locked to the wall inside the room by a pin, and its anti-theft window function can be used normally under normal circumstances. The supporting base plate 3, adjusting side plate 4, and inner baffle 2 are all made of epoxy resin.

One outer side of the angle steel 72 is fixedly connected to the web surface of the T-shaped steel 71, the top of the angle steel 72 is fixedly connected to the inner surface of the flange of the T-shaped steel 71, and the bottom of the angle steel 72 is fixedly connected to the wall at the window.

[0052] Among them, two first limiting slots 31 are symmetrically provided on the left end surfaces of the support base plate 3. The inner end of the first limiting slot 31 is provided with a first spring mounting hole 32 for installing the first support spring 34. The top of the first support spring 34 is connected to a first limiting block 33. A first clamping gap is left between the first limiting block 33 and the stop member 8, which is adapted to the adjustment side plate 4.

[0053] The first limiting block 33 is a triangular prism structure. The upper and lower bottom surfaces of the triangular prism structure are parallel to the inner baffle 2. The side of the triangular prism structure includes a first vertical surface 331 that is parallel to the adjusting side plate 4. The bottom end of the first vertical surface 331 is provided with a first plane 332. The boundary of the first plane 332 is slidably connected to the inner wall of the first limiting slot 31. A first inclined surface 333 is provided between the first vertical surface 331 and the first plane 332.

[0054] In actual use, the right adjustment side plate 4 is disassembled and rotated and moved to the first clamping gap position. During the movement, it will pass through the first inclined surface 333. The first limit block 33 will bounce up again under the action of the first support spring 34 to limit the position.

[0055] The fire-resistant space is also equipped with a supporting top plate. Two second limiting slots are symmetrically arranged on the left side surfaces of the supporting top plate. The inner end of each second limiting slot has a second spring mounting hole for installing a second supporting spring. A second limiting block is connected to the top of the second supporting spring. A second locking gap, adapted to the adjusting side plate, is left between the second limiting block and the stop. The surface structure of the supporting top plate is the same as and symmetrically distributed with the surface structure of the supporting bottom plate 3.

[0056] The bottom of the first escape ladder 5 is hinged to the bottom frame 13 by two first hinges 9, and the top of the second escape ladder 6 is hinged to the top of the first escape ladder 5 by two second hinges; the escape ladders are connected by hinges to facilitate their rapid operation and flipping descent.

[0057] The first escape ladder 5 includes two parallel first longitudinal beams 51, and several first cross beams 52 are evenly distributed between the two first longitudinal beams 51.

A sliding connecting rod is provided inside the first longitudinal beam 51. The diameter is slightly smaller than the side length of the square tube. Specifically, it is a stainless steel round rod. After the escape ladder is deployed, the stainless steel round rod in the first escape ladder 5 quickly falls to the middle of the second longitudinal beam 61 of the second escape ladder 6, thereby using gravity to fix it between the first escape ladder 5 and the second escape ladder 6, enhancing the stability and safety of the escape ladder.

[0060] The second longitudinal beam 61 is a square tube structure, and a central clamping plate is provided in the middle of the second longitudinal beam 61.

[0061] Among them, the stop 8 is an L-shaped metal sheet, and there are two stop 8s, which are fixed on the left side of the support base plate 3 and the left side of the support top plate respectively.
