[0025] Please refer to Figure 1-7 , the present utility model provides a technical solution:
[0026] An automatically locking fire safety rope, comprising an installation stabilizing platform 1 and a support box 2.

[0027] As a further implementation of this solution, the inner side of the support box 2 is hollowly opened. A through hole is opened at the front end of the support box 2. The outer side of the rope wheel assembly 5 is rotatably connected inside the through hole of the support box 2, installing the rope wheel assembly 5 and the locking assembly 6 inside the support box 2, and at the same time facilitating the rotation of the roller column 54 when the hand crank 51 rotates.
[0028] As a further implementation of this solution, one side of the connecting plate 41 is fixedly connected to the inner side of the left end of the support box 2. The shape of the brake disc ring 42 is a hollow cylinder. The clamping rotation groove 43 is opened as a hollow cylinder. A through hole is opened at the upper end of the brake disc ring 42. The lower end of the reset extrusion plate 8 slides inside the through hole at the upper end of the brake disc ring 42. The lower end of the baffle 44 protrudes from the inner side of the brake disc ring 42, facilitating the reset extrusion plate 8 to squeeze the rubber sleeve hard plate 69 and reset the rubber sleeve hard plate 69.
[0029] As a further implementation of this solution, the rope wheel assembly 5 includes a hand crank 51. One side of the hand crank 51 is fixedly connected to a roller column 54. One side of the roller column 54 is fixedly connected to a wire reel 52. A second safety rope 53 is installed on the outer side of the wire reel 52. The shape of the roller column 54 is a cylinder. The roller column 54 is rotatably connected to the inner side of the support box 2. The hand crank 51 protrudes outside the support box 2. A through hole is opened at the lower part of the support box 2. The second safety rope 53 passes through and slides inside the through hole of the support box 2, playing a role in limiting the wire reel 52 and at the same time facilitating the operation of the hand crank 51 to store the second safety rope 53.
[0030] As a further implementation of this solution, the shape of the rotation stop disc 61 is a hollow cylinder, the number of locking components 6 is two, one side of the spring telescopic rod 63 is fixedly connected to the outer side of the roller column 54, the number of block chutes 62 is several, and limit chutes are opened at both ends of the block chute 62, which plays a role in moving the gravity slider 64 under the action of centrifugal force when the rotation stop disc 61 rotates rapidly;
[0031] As a further implementation of this solution, a limit slider is fixedly installed on the outer side of the gravity slider 64, the number of each group of limit ear seats 65 is two, a countersunk head hole is opened on the inner side of the limit ear seat 65, the outer side of the clockwork spring 67 is fixedly connected to the inner side of the countersunk head hole of the limit ear seat 65, the shape of the column rotation limit rod 66 is a cylinder, a notch is opened on the inner side of the brake piece 68, and one side of the rubber sleeve hard board 69 is attached to one side of the gravity slider 64, which can prevent the wire reel 52 from rotating and prevent the second safety rope 53 from continuing to extend. At this time, the flow rate of the second safety rope 53 can be slowly reduced.
[0032] Workflow: During the use of the device, the buckle at the bottom of the second safety rope 53 is installed on the firefighter. The first safety rope 3 directly scatters into the air. The firefighter descends through the first safety rope 3. During the descent, the second safety rope 53 gradually flows out of the support box 2. The second safety rope 53 drives the wire reel 52 to rotate. The second safety rope 53 drives the locking assembly 6 to rotate through the roller column 54. The roller column 54 is rotatably connected to the inner side of the support box 2, playing a role in limiting the rotation of the wire reel 52. During the descent, the firefighter controls the descending speed of the second safety rope 53. If the firefighter accidentally falls, the outflow speed of the second safety rope 53 is relatively large. At this time, the rotation speeds of the wire reel 52 and the roller column 54 are relatively fast, and the rotation speed of the locking assembly 6 is equally fast. Under the action of centrifugal force, the gravity slider 64 moves away from the center of the rotation stop disk 61. The gravity slider 64 is slidably connected to the inner side of the block chute 62 through the limit slider, playing a role in limiting the movement of the gravity slider 64. The gravity slider 64 drives the limit ear seat 65 to move, and the gravity slider 64 pulls the spring telescopic rod 63 to stretch. When driven by the limit ear seat 65, the brake pad 68 moves. The brake pad 68 fits against the inner side of the brake disc ring 42. Under the action of friction, the rotation speed of the roller column 54 can be gradually controlled. After the brake pad 68 contacts the inner side of the brake disc ring 42, the brake pad 68 is squeezed and rotates. The brake pad 68 drives the column rotation limit rod 66 to rotate. The column rotation limit rod 66 is rotatably connected to the inner side of the limit ear seat 65, playing a role in limiting the brake pad 68. The column rotation limit rod 66 drives the clockwork spring 67 to deform. One end of the brake pad 68 is provided with a notch to prevent the brake pad 68 from colliding with the baffle 44. When the brake pad 68 rotates a certain angle, the rubber sleeve hard board 69 contacts the baffle 44. At this time, under the friction force between the rubber sleeve hard board 69 and the baffle 44, the rotation of the wire reel 52 can be prevented, and the continuous extension of the second safety rope 53 can be prevented. At this time, the flow rate of the second safety rope 53 can be slowly reduced, and at the same time, the second safety rope 53 can be locked to protect the safety of the firefighter.

The scope of the present invention is defined by the appended claims and their equivalents.
