Among them, the rectangular friction plate and the semicircular friction plate are fixed in pairs on both sides of the inner side of the shell, and the rectangular friction plate and the semicircular friction plate correspond to the load-bearing fireproof rope. The upper semicircular friction plate is connected with the long rod, and the lower The semicircular friction plate is connected with the short rod, the long rod and the short rod are hinged, the spring is installed between the short rod and the long rod, and the two ends are respectively arranged on the long rod and the short rod, and the brake control handle is installed on the long rod and the short rod .

Preferably, the brake control handle is made of heat insulating material.

Preferably, the semicircular friction plate is provided with a guide block and a guide slide rail in contact with the load-bearing fireproof rope.

Preferably, the safety belt is provided with a safety clip for clamping the load-bearing fireproof rope.

Preferably, the safety rope fixing ring is provided with a deployment bracket.

Beneficial effects of the present invention:

1) Self-help escape, fast and efficient: using the self-rescue slow-descent device of the present invention, one can perform escape behavior by oneself without waiting for external rescue, which greatly improves the success rate of escape.

2) Simple operation: the device of the present invention is easy to operate, which is convenient for users to grasp and use quickly.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The present invention provides a self-rescue slow descent device, which includes a safety rope fixing ring 1, a safety hook 3, a safety belt 5, a load-bearing fireproof rope 9, a casing 11 and two rectangular friction plates 2, 7 arranged in the casing 11 , brake control handle 4, two semicircular friction plates 6, 8, long rod 12 and short rod 17; the safety rope fixing ring 1 is connected to the upper end of the load-bearing fireproof rope 9; the safety hook 3 is arranged on the outside of the housing 11 And be connected with safety belt 5;

Among them, the rectangular friction plate and the semicircular friction plate are fixed in pairs, one side is high and the other is low, and they are fixed on both sides of the inner side of the housing 11, and the rectangular friction plate and the semicircular friction plate correspond to the load-bearing fireproof rope, and the upper semicircular friction plate 6 is connected to the long rod. , the semicircular friction plate 8 below is connected with the short rod, the long rod and the short rod are hinged, the spring 15 is installed between the short rod and the long rod and the two ends are respectively arranged on the long rod and the short rod, and the long rod and the short rod Brake control handle 4.

The working process of the present invention is as follows: as shown in Figure 1, when a fire breaks out and the situation is urgent, the load-bearing fireproof rope 9 is connected with the safety rope fixing ring 1 through the safety hook 3, and the connected load-bearing fireproof rope 9 is pulled out of the window Throw it downstairs; after the person wears the safety belt 5, the safety belt 5 is bound by the safety hook 3. Then the load-bearing fireproof rope 9 is wound on the slow-down device according to the mode of Fig. 1; in the process of descending along the load-bearing rope, the left hand grasps the load-bearing fireproof rope 9, and the right hand presses the brake control handle 4, because the load-bearing fireproof rope 9 and The friction between the upper semicircular friction plate 6 and the lower semicircular friction plate 8 will reduce the descending speed; but if the descending speed is still too high, you can firmly press the brake control handle 4 to push the two brakes through the long rod and the short rod. The semicircle brake pad moves to the rectangular friction pad 2 above and the rectangular friction pad 7 below, and due to extrusion and double-sided friction, the speed is greatly reduced, and even stops falling. Because the speed can be controlled in a large range, it can quickly pass through places where the fire is serious. After the first person descends to a certain height, after the second person is installed according to the above-mentioned mode, he can fall along the load-bearing fireproof rope. In this way, the multi-purpose purpose of one device can be realized, without excessive waiting, and the critical time of self-rescue is well utilized. As shown in Figure 2, the guide rail 16 is located directly below the semicircular brake pad, and the semicircular friction pad is fixedly connected to the guide block 10. Press the brake control handle, and the long rod and the short rod will move, pushing the guide block and the semicircular brake pad. The discs move along the guide rail together, and the T-shaped guide rail has an upward support for the semicircular brake disc, which prevents the semicircular brake disc from moving downward due to the force of the load-bearing fireproof rope on the semicircular brake disc, while the rectangular friction disc is fixed on the Inside the shell.

In another embodiment, the safety belt is provided with a safety clip for clamping the load-bearing fireproof rope. This can further protect the safety of the user. When the device is out of hand or malfunctions, the user will still hang on the load-bearing fireproof rope, and can escape by himself with the help of the load-bearing fireproof rope.

Further, the safety rope fixing ring 1 is provided with a deployment bracket. This is for the backup design that the deployment bracket can be hung on a part such as a window sill when there is no fixed position for the safety rope fixing ring 1 .

The self-rescue slow-descent device provided by the present invention has been introduced in detail above. In this paper, specific examples are used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only used to help understand the method and methods of the present invention. its core idea. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
