DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution for a fire emergency slow-down escape device: a fire emergency slow-down escape device, comprising a shell 1, a deceleration plate mechanism is arranged inside the shell 1, a rope mechanism is also arranged inside the shell 1, a fixing mechanism is also arranged on the rope mechanism, the deceleration plate mechanism comprises two bidirectional screws 2 rotatably mounted inside the shell 1 and arranged in parallel, each thread of each bidirectional screw 2 is provided with a first thread seat 3, an annular deceleration plate 4 is commonly installed between the two first thread seats 3 on each same thread, one end of each bidirectional screw 2 extends to the outside of the shell 1 and is provided with the same The step wheel 5 and the two synchronous wheels 5 are jointly provided with a synchronous belt 6. The end of one of the bidirectional screws 2 is installed with a first knob 7 on one side of the synchronous wheel 5. Rotating the first knob 7 drives the corresponding bidirectional screw 2 to rotate, and then the rotating bidirectional screw 2 drives the other bidirectional screw 2 to rotate in the same direction through the synchronous wheel 5 and the synchronous belt 6, thereby driving the two first threaded seats 3 on each group of bidirectional screws 2 away from each other, and thus driving the two annular speed reduction plates 4 away from each other. At the same time, each annular speed reduction plate 4 is not in close contact with the damping plate 9, and the annular speed reduction plate 4 will not play a damping role on the rotating winding rod 8 of the recovery rope 17.

[0021] The rope mechanism includes a winding rod 8 rotatably mounted on the inner wall of the housing 1 and between the two bidirectional screws 2. The diameter of the winding rod 8 is the same as the inner diameter of the annular speed reducer 4. A damping plate 9 is installed on the surface of the winding rod 8 between the two annular speed reducers 4 and is closely attached to the adjacent annular speed reducers 4. One end of the winding rod 8 extends to the outside of the housing 1 and is installed with a side plate 10. A handle 11 is installed on the side of the side plate 10 near the lower end. A rope 17 is wound between the two damping plates 9 on the surface of the winding rod 8. One end of the rope 17 is fixedly connected to the winding rod 8, and the other end extends to the outside of the housing 1 and is installed with a safety belt. The upper surface of the housing 1 A lifting ring 18 is installed in the center, and the entire device can be installed by hanging the lifting ring 18 on a horizontal bar on the wall of a building. The user puts the safety belt on himself and descends from the upstairs. When the user freely descends, the gravity generated causes the winding rod 8 to rotate, so that the rope 17 is unfolded from the winding rod 8. Because the two annular speed reduction plates 4 are in close contact with the corresponding damping plates 9, when the rotating winding rod 8 drives the damping plate 9 to rotate, each annular speed reduction plate 4 can damp the rotating damping plate 9 in close contact with it, thereby reducing the rotation speed of the winding rod 8, so that the user slowly descends to the ground and achieves the purpose of escape.

[0022] The fixing mechanism includes an inner cavity 12 opened inside the handle 11, and a one-way screw 13 is rotatably installed in the inner cavity 12. A second threaded seat 14 adapted to the inner cavity 12 is arranged on the one-way screw 13. Two card slots are correspondingly opened on the side of the shell 1 on one side of the second threaded seat 14. Each second threaded seat 14 is provided with a card member 15 extending into the inner cavity 12 and fixedly connected to the second threaded seat 14. One end of the one-way screw 13 extends to the outside of the handle 11 and is installed with a second knob 16. Rotating the second knob 16 drives the one-way screw 13 to rotate. The rotating one-way screw 13 drives the second threaded seat 14 to move and drives the two card members 15 to move out of the card slot to release the fixation of the winding rod 8.

[0023] The working principle of the utility model is as follows: the whole device can be hung on the horizontal bar on the wall of the building through the hanging ring 18 to complete the installation of the device. When encountering fire danger and needing to escape, the second knob 16 is rotated to drive the one-way screw 13 to rotate. The rotating one-way screw 13 drives the second threaded seat 14 to move and drives the two clamps 15 to move out of the clamping slot to release the fixation of the winding rod 8. Then the user puts the safety belt on himself and descends from the upstairs. When the user freely descends, the gravity generated causes the winding rod 8 to rotate, so that the rope 17 is unfolded from the winding rod 8. Because the two annular speed reduction plates 4 are in close contact with the corresponding damping plates 9, when the rotating winding rod 8 drives the damping plate 9 to rotate, each annular speed reduction plate 4 can play a damping role on the rotating damping plate 9 in close contact with it, thereby reducing the rotation speed of the winding rod 8, so that the user can slowly descend to the ground and achieve the purpose of escape.

[0024] When the recovery device is in operation, rotating the first knob 7 drives the corresponding bidirectional screw 2 to rotate, and then the rotating bidirectional screw 2 drives the other bidirectional screw 2 to rotate in the same direction through the synchronous wheel 5 and the synchronous belt 6, thereby driving the two first threaded seats 3 on each group of bidirectional screws 2 away from each other, and thus driving the two annular speed reduction plates 4 away from each other, and then rotating the winding rod 8 through the side plate 10 and the handle 11 to rewind the rope 17 on the winding rod 8. At the same time, each annular speed reduction plate 4 is not tightly attached to the damping plate 9, and the annular speed reduction plate 4 will not damp the rotating winding rod 8 of the recovery rope 17, thereby facilitating the recovery of the rope 17, and then aligning the two clamps 15 with the clamping slot, reversing the second knob 16 drives the one-way screw 13 to reverse and drive the two clamps 15 to re-enter the clamping slot, fix the winding rod 8, and the operation is completed.
