Clamping-overhanging rail for escape of window and installing method thereof

Abstract

The invention discloses a window escape clamp cantilever and a method of installing the cantilever. The clamp cantilever includes a locking nut, a slide clamp arm, a pull arm, a fixing clamp arm and a supporting cantilever; one end of the pull arm is provided with outer thread, and the thread circumference is provided with at least a cutting plane; the other end of the pull arm and the fixing clamp arm form an angle less than or equal to 90 degrees, and are fixed and connected; the fixing clamp arm and the supporting cantilever are connected; the supporting cantilever is provided with a hole and/or a hook, which is connected with other lifesaving equipments; one end of the slide clamp arm is provided with a through hole, the size of which adapts to the cross section of a thread part of the pull arm, so that the slide clamp arm can slide back and forth on the thread part of the pull arm, but not rotate; the slide clamp arm and the fixing clamp arm are on the same side of the circumference of the pull arm; the locking nut can rotate at the thread part of the thread part of the pull arm, so that the slide clamp arm can slide back and forth on the pull arm. The clamp cantilever of the invention is characterized by simple structure, convenient installation, high reliability, strong bearing capacity, etc., and can be used as a piece of general equipment for escaping from indoor disaster in high-rise buildings.

Description

technical field [0001] The invention relates to an escape equipment and an installation method thereof, in particular to an escape fixing device for a window and an installation method thereof. Background technique [0002] Among many disasters, fires, earthquakes, and terrorist incidents in buildings are the most sudden, and they cause the greatest casualties to human beings. Building disasters require reliable fixation and simple operation for escape and refuge equipment. And the device that can be used for temporary fixation in present civil self-rescue escape refuge equipment almost only has a kind of soft rope, and when using soft rope, require it to be fixed on other articles in the house. The use of soft ropes has greater risks, mainly including: [0003] 1. Use a soft rope to fix the items in the object, and it is difficult to connect firmly. [0004] 2. Even if the connection is firm, it is difficult to make the refuge equipment leave the wall and hang in the air...

AI Technical Summary

Problems solved by technology

[0003] 1. Use a soft rope to fix the items in the object, it is difficult to connect firmly

[0004] 2. Even if the connection is firm, it is difficult to make the evacuation equipment leave the wall and hang in the air, so the escape personnel can only slide and friction on the wall to escape, and casualties are inevitable

[0005] 3. If there are no fixed items in the house, even life-saving equipment cannot be used

[0006] 4. For ordinary people, even if they can find fixed items indoors, it is often difficult to fix the soft rope firmly due to psychological tension in the event of a disaster

[0007] Therefore, the self-rescue fixing device of the soft rope is not suitable for use as a civil building self-rescue device with high requirements on practicability and safety.
