Detailed Description

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

In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of other ways than those described herein, and those skilled in the art will be able to make similar generalizations without departing from the spirit of the invention. The invention is therefore not limited to the specific embodiments disclosed below.

The multi-storey building is a building with the building height of more than 10 meters and less than 24 meters and the building number of stories of more than 3 and less than 7. If a simple escape device is provided after fire occurs in the multi-storey building house, self rescue is easy. However, people on the balcony side of the multi-storey building are often provided with clothes hangers or sunshades 7, particularly the bottom layer, and the window is also provided with an anti-theft net, so that a lot of obstacles exist, and the people can easily be injured when directly sliding down the window along the lifesaving rope.

Referring to fig. 1 and 2, the multi-storey residential fire escape device comprises an escape frame 1, wherein the escape frame 1 comprises a horizontal plate 101, an inclined cantilever lever 102 is arranged at the front half section of the horizontal plate 101, a rope pulley 103 is horizontally arranged on the cantilever lever 102, and a life-saving rope 104 is wound on the rope pulley 103; the rear half part of the horizontal plate 101 is provided with a U-shaped clamping plate 106 with a lower opening, and the opening width of the U-shaped clamping plate 106 is matched with the thickness of the outer wall 5 at the position of the residential window; the speed-limiting device also comprises a plurality of speed-limiting sliding cylinders 2, and each speed-limiting sliding cylinder 2 is connected with a net bag 3.

In the above embodiment, an escape frame 1 is provided, where the escape frame 1 includes a horizontal plate 101, the front half section of the horizontal plate 101 is provided with an inclined cantilever 102, the cantilever 102 is provided with a rope pulley 103, a life saving rope 104 is wound on the rope pulley 103, and the rear half section of the horizontal plate 101 is provided with a U-shaped clamping plate 106 with a downward opening. After a fire disaster occurs, the U-shaped clamping plate 106 is clamped on the outer wall 5 of the window, the lifting rod 102 faces the outside of the window, the lifesaving rope 104 is thrown downstairs, and after the escape personnel penetrates the net bag 3, the escape personnel stand on the horizontal plate 101 and slide down along the lifesaving rope 104 by using the speed-limiting sliding barrel 2. Because the cantilever rods 102 extend out of the window for a certain distance, the clothes hanger, the awning 7 or the protective net arranged outside the window in the lower-layer residence is avoided. Due to the adoption of the speed-limiting sliding barrel 2, the descending speed of the escape personnel is not too high. The length of the lifeline 104 is greater than the height of the floor on which the evacuee is located. Referring to fig. 3, during escape, if someone is downstairs, the person downstairs can be asked to tie the free end of the life line 104 to the downstairs big tree 6, the parking space limiting cross bar or other fixtures. Referring to fig. 4, if there is no one downstairs, the evacuee slides down the lifeline 104 vertically.

Further, the ram 102 includes two inclined rams 102, a rope pulley 103 is disposed between the top ends of the two rams 102, and a connecting rod 105 is disposed in the middle of the two rams 102.

In the above embodiment, the take-up levers 102 specifically include two inclined take-up levers 102, the rope pulley 103 is provided between the top ends of the two take-up levers 102, and the link 105 is provided at the middle of the two take-up levers 102. Due to the adoption of the lever, the evacuee can walk between the two ram rods 102 to the lower part of the rope pulley 103. Preferably, the roots of the two take-up levers 102 are hinged to the horizontal plate 101, the horizontal plate 101 is provided with an angle limiting column 107, and the angle limiting column 107 is located on the horizontal plate 101 in front of the hinged position of the take-up levers 102, so that the two take-up levers 102 can rotate forwards to an inclined state and rotate backwards to be parallel to the horizontal plate 101. The escape device is folded and stored when not in use, so that the space is saved, and when in use, the two ram rods 102 are rotated and unfolded.

Further, the inner surface of the speed-limiting slide cylinder 2 is provided with a rubber layer, and the rubber layer is tightly wrapped on the lifesaving rope 104.

In the above embodiment, the rubber layer with a large friction coefficient is arranged on the inner surface of the speed-limiting sliding barrel 2, so that the escape person can slide slowly in the sliding process.

Further, referring to fig. 1, the outer surface of the lifeline 104 is provided with a speed limiting protrusion 108. The height of the speed limiting protrusions 108 is equal and evenly distributed on the outer surface of the lifeline 104.

In the above embodiment, in order to increase the friction force between the lifesaving rope 104 and the speed-limiting slide barrel 2, the speed-limiting protrusions 108 are uniformly distributed on the outer surface of the lifesaving rope 104. The speed-limiting bulges 108 are uniformly distributed, the friction force between the speed-limiting sliding drum 2 and the lifesaving rope 104 is uniform in the sliding process, and the speed-limiting sliding drum 2 can slide stably.

Further, the height of the speed-limiting protrusions 108 is gradually increased from top to bottom, and the distribution number of the speed-limiting protrusions 108 is gradually increased from top to bottom.

In order to ensure that the floor can be fallen at a low speed when falling to the ground, it is preferable in the above embodiment that the height of the speed-limiting protrusions 108 is gradually increased from top to bottom and the number of the speed-limiting protrusions 108 is gradually increased from top to bottom.

Further, referring to fig. 1, the lower end of the life line 104 is provided with a quick release buckle 4.

In the above embodiment, in order to facilitate downstairs personnel to quickly fix the lifesaving rope 104 on the downstairs big tree 6, the parking space stop rod or other fixed objects, the end of the lifesaving rope 104 is provided with the quick-release lock catch 4.

Furthermore, the quick-release lock catch device further comprises a ground nail, and a fixing ring matched with the quick-release lock catch 4 is arranged on the ground nail.

Sometimes, big trees, parking space limiting rods or other fixed objects are not arranged downstairs, so that the life line 104 is conveniently fixed by downstairs, and the end part of the life line 104 is provided with a ground nail, so that downstairs can conveniently fix the life line 104 on the ground.

Although the invention has been described in detail in this specification with reference to specific embodiments and illustrative embodiments, it will be apparent to those skilled in the art that certain changes and modifications can be made therein without departing from the scope of the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
