[0021] 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.

[0022] See also Figures 1 to 5 , the utility model provides a technical solution:

[0023] An adjustable fire ladder comprises a first fire ladder 1 and a second fire ladder 12. The first fire ladder 1 is sleeved with anti-skid sleeves 3 at both ends of the bottom to prevent sliding, and a plurality of steps are installed inside the first fire ladder 1. Velcro tapes 4 are bonded to the top ends of the steps, and anti-skid pads 5 are bonded to the top of the Velcro tapes 4. Reflective strips 6 are bonded to the upper and lower parts of the two ends of the front of the first fire ladder 1; a rubber protective pad 2 is bonded to the bottom of the steps by glue for protecting the shoulders of firefighters when carrying the ladder.

[0024] The utility model provides a first fire ladder 1, a rubber protective pad 2, an anti-skid cover 3, a hook and loop fastener 4, an anti-skid pad 5 and a reflective strip 6 for use together, thereby greatly improving the safety of firefighters when using the ladder, and also facilitating the improvement of the stability of the ladder when used by the firefighters, thereby reducing the occurrence of dangerous accidents.

[0025] A connection seat 7 is fixedly installed at the center of the step surface at the top of the first fire ladder 1, and a limit cover 8 is installed on the top of the connection seat 7, and a roller 9 is rotatably installed inside the limit cover 8. Slide grooves 10 are opened at both ends of the back of the first fire ladder 1, and a slider 11 is slidably connected inside the slide groove 10, and one end of the slider 11 is fixedly connected to the second fire ladder 12. Hooks 13 for hanging the entire fire ladder are installed above the two ends of the back of the second fire ladder 12, and a groove ring seat 14 is installed at the center of the top surface of the step at the bottom of the second fire ladder 12, and a through hole is opened on the inner surface of the groove ring seat 14, and a rope 15 is wound inside the through hole, and the rope 15 is fixedly connected to a handle 16 through one end of the roller 9.

[0026] The utility model provides the above components for use in combination, so that the second fire ladder 12 can be lifted and lowered, and the operation is also convenient, thereby realizing the adjustable type.

[0027] By holding the handle 16 with the hand, the rope 15 is pulled down, and then the rope 15 is rotated by the roller 9. At the same time, the other end of the rope 15 is wound in the through hole opened inside the groove ring seat 14. When the second fire ladder 12 is pulled up, the slider 11 on it slides in the slide groove 10, so that it is easy to pull it up with a lighter force to increase the height of the fire ladder.
