[0002] The fire ladder is a firefighting tool that can play a very important role in firefighting. When you need to go to higher floors during a fire and the road stairs are closed, you need to use a fire ladder. At present, there are more and more high-rise buildings such as shopping malls, residences, and office buildings, and the application of fire ladders is becoming more and more extensive. Fire ladders in public places such as residences, shopping malls, and hotels have also become an indispensable item.

[0003] Most of the existing emergency rescue fire ladders are one ladder section on another sliding, and use pulleys and other equipment to make it possible to quickly extend and retract, so that it can be placed on the side of a window, allowing firefighters to climb up a high building to put out a fire.

[0004] However, the existing fire ladders are structured in such a way that the ladders are stacked one on top of another, which may slow down the climbing efficiency of firefighters. Firefighters may also step on the wrong ladder when they are distracted, which may easily affect their personal safety. In addition, most people's windows are locked, which requires firefighters to carry additional equipment to break the windows. This brings great inconvenience to firefighters at work. Therefore, we propose a fire ladder for emergency rescue. Utility Model Content

[0024] See also Figures 1 to 6 The utility model provides a technical solution: an emergency rescue fire ladder, comprising a first ladder 1, the top of the first ladder 1 is rotatably connected to the second ladder 2, the first ladder 1 and the second ladder 2 are fixedly connected to an L-shaped fixing block 12 on one side and at the corresponding two ends close to each other, the bottom of one L-shaped fixing block 12 is fixedly connected to a second clamping block 13, the top of the other L-shaped fixing block 12 is provided with a fifth groove 18, the inside of the other L-shaped fixing block 12 and on both sides of the fifth groove 18 are provided with a fourth groove 16, the inside of the fourth groove 16 is provided with a second spring 15, one end of the second spring 15 and the inside of the fourth groove 16 are fixedly connected to a third clamping block 17, the third clamping block 17 is slidably connected to the fourth groove 16, one side of the third clamping block 17 and the inside of the fourth groove 16 are fixedly connected to a pull rod 14, the pull rod 14 penetrates and is slidably connected to another L-shaped The fixing block 12 and the second clamping block 13 are slidably connected with the fifth groove 18, and the top and corresponding two sides of the second ladder 2 are provided with a window breaking mechanism. The second ladder 2 is rotated so that the second clamping block 13 at the bottom of the L-shaped fixing block 12 fixed to the second ladder 2 is inserted into the inside of the fifth groove 18, and the second clamping block 13 squeezes the third clamping block 17 into the inside of the fourth groove 16 and compresses the second spring 15. When the second clamping block 13 completely enters the inside of the fifth groove 18, the second spring 15 rebounds and squeezes the third clamping block 17 back into the second clamping block 13 to be stuck, so that the first ladder 1 and the second ladder 2 are fixed together. When encountering a locked window, the first ladder 1 is shaken so that the bottom of the first ladder 1 rotates inside the sixth groove 20 opened in the fixing block 23, driving the window-breaking needle 26 at the top of the second ladder 2 to hit the window, so that the window is broken and enters the interior of the house for rescue.

[0025] The window breaking mechanism includes two fixing columns 29, which are fixedly connected to the top of the second ladder 2 and the corresponding two sides. A fixing strip 27 is fixedly connected to the top of the fixing column 29, and a clamping strip 25 is fixedly connected to the bottom of the fixing strip 27 and the side away from the fixing column 29. A window breaking needle 26 is fixedly connected to one end of the fixing strip 27 and the side close to the clamping strip 25.
