Detailed ways:

This new type is a protective fence made of stainless metal installed on the outside of the window, which integrates escape and anti-theft. Its technical idea is to realize the anti-theft function and escape function through the organic combination and effective cooperation of the three frames. In daily life, the inner and outer frames of the "automatic ladder guardrail" consolidate the anti-theft function of the guardrail; when a fire occurs, the "automatic ladder guardrail" will exert an escape function superior to other guardrails— - Automatic erection of escape ladders. When the power is on, the personnel at the fire scene can automatically set up an escape ladder to achieve the purpose of escape by pressing the indoor control button. In case of power failure, the backup device can be manually installed, and an escape ladder can also be erected.

As shown in the figure, the structure of the present invention is as follows:

It includes frame body 1, outer frame 2 and inner frame 3; the frame body is a large outer frame for installing all structures, and plays the role of fixing the entire guardrail and running carrier.

The inner frame 3 is ladder-shaped, installed on the frame body 1 through guide rails, and can slide freely along both sides of the frame body 1; the top of the outer frame 2 is connected to the top of the frame body 1 by a hinge and can be turned outward; A support for supporting the outer frame 2 when opened is provided between the frame body 2 and the frame body 1 .

The inner frame is shaped like a ladder and can slide freely along both sides of the frame. It is divided into upper and lower parts: the upper part (very short enough to fix an electric lock) is connected and fixed with the frame through the electric lock, and the electric lock can be opened through the button to make the inner frame slide down to realize the purpose of erecting the escape ladder. The upper and lower parts are connected by a manual device. When the power is off, the manual device can be opened to separate the lower part from the upper part and slide down, which can also achieve the purpose of erecting an escape ladder.

The top of the foldable outer frame is fixed on the frame body, and the bottom is fixed on the frame body through a hidden lock. After opening the concealed lock, the foldable outer frame can be turned outward. After the inner frame slides, open the concealed lock, and the outer frame can be turned outwards to provide an escape channel. Only by stepping on the inner frame that has slid down and built a ladder can escape from the fire scene.

As shown in Figure 2, it also includes a control circuit for centralized control of the automatic elevator guardrails on each floor. It is characterized in that: the switches and power supplies on each floor are connected in parallel, and the electric locks 4 on each floor are connected in series on this floor and the lower floor. Between the circuits, the electric lock on the first floor forms a closed circuit with the switch and power supply on the first floor. Take the third floor as an example: when a fire breaks out on the third floor, turn on the power, switch S1 is closed, so that the electric locks below the third floor form a circuit, and work at the same time, the electric locks are opened, and the inner frame of the protective fence slides down to form a ladder automatically.

The switch is a manual switch or an automatic fire alarm device, specifically a smoke sensor, an infrared sensor, a temperature sensor and the like.
