[0034] See also Figure 1-7 The present invention provides a technical solution: a multifunctional escape and rescue ladder, which can be converted into a daily ladder and an escape ladder to improve the escape safety of a family in an emergency such as a fire. The rescue ladder includes a frame 1 and a frame 2 as the main body of the rescue ladder. The frame 1 and the frame 2 are both provided with pedals 3. The pedals 3 have rubber protrusions 13 to further increase the friction when stepping on them, thereby avoiding slipping and stepping on empty space during use. To avoid rust, a varnish made of environmentally friendly materials is coated on the aluminum alloy ladder body to effectively prevent the ladder from rusting, thereby improving the service life and aesthetics. A hinge 4 is installed at the connection position between the frame 1 and the frame 2. The rescue ladder has the working forms of a straight ladder and a triangular ladder. In order to ensure the stability of the triangular ladder, a lock hook 10 that can be retracted and rotated is provided on the frame 1, and a hook point 11 is provided on the frame 2. The end of the lock hook 10 can be stuck on the hook point 11 to achieve the stability of the triangular ladder. The rotation angle range of the hinged portion 4 is 0°-180°, so that in a straight ladder state, no bending occurs and support can be provided.

[0035] The outermost ladder feet of the frame 1 and the frame 2 2 are provided with rubber foot covers 12 to increase the friction of the ladder feet and avoid slipping during use.

[0036] The frame 1 and the frame 2 2 are both composed of a plurality of unit sections, wherein a rope 5 is arranged between two adjacent unit sections for extending the total length of the rescue ladder body after stretching, and the rope 5 is made of a flexible steel cable; the unit sections of the frame 1 and the frame 2 2 are connected by plugging, and after the plug-in installation, the rescue ladder is combined into one under the action of gravity, wherein the interior of the unit section is a hollow cavity, and the frame 1 1, the frame 2 2 and the pedal 3 are made of aluminum alloy as a whole.

[0037] Specifically, in order to ensure the stability of the rope 5 when in use, and to ensure that the rope can be stably unfolded and stored before and after use, one end of the rope 5 is fixedly mounted on the pedal 3 of a unit section, and the other end is fixed on the limit plate 7, which is arranged at the lower end of the rope 5. The limit plate 7 can slide in the hollow cavity inside another adjacent unit section, and a linear slideway 8 is arranged in the hollow cavity inside the unit section and slides with the outer end sliding part 9 of the limit plate 7. After the limit plate 7 slides to the maximum sliding stroke, the maximum extension length between the two unit sections is reached.

[0038] In case of need for escape, when unfolding the rescue ladder, one end of the rescue ladder needs to be fixed on some fixed objects, which places certain requirements on the fixed objects, and also requires certain requirements on the fire resistance and firmness of the fixed ropes. In order to solve such problems, the frame 1 or the frame 2 2 is provided with a deployable hook 6, which can be hooked on the fixed object after being unfolded in case of escape.

[0039] Specifically, the hook 6 is installed at the outermost end of frame 1 or frame 2 2 near the ladder foot, and the hook 6 is divided into a horizontal bar section 61 and a vertical bar section 62. The horizontal bar section 61 and the vertical bar section 62 are hingedly installed, and the horizontal bar section 61 and the unit section are hingedly installed. An inner groove 1 63 is provided in the horizontal bar section 61 for accommodating the vertical bar section 62, and an inner groove 2 64 is provided in the unit section for accommodating the horizontal bar section 61. When fully unfolded for use, the horizontal bar section 61 maintains a horizontal limit, and the vertical bar section 62 maintains a vertical limit.
