DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

A foldable climbing ladder, as shown in FIGS. 1 , 2 , 3 and 4 , comprises a first main body 10 and a second main body 11 which are hinged to each other, the tops of the first main body 10 and the second main body 11 being hinged to each other, and specifically, the top surfaces of the first main body 10 and the second main body 11 are both provided with mounting grooves, the hinges are located in the mounting grooves and fixed by bolts;

The second body 11 can be flipped to the top of the first body 10 to increase the climbing height. The tops of the first body 10 and the second body 11 are both provided with a socket 20. The wall of the first body 10 is slidably connected with a plug rod 21. The plug rod 21 can be inserted into the socket 20 of the second body 11 to limit the relative rotation of the first body 10 and the second body 11. The wall of the first body 10 is provided with a locking structure for positioning the plug rod 21. The locking structure includes a sliding body 22, a positioning groove 23 and a slide groove 24. The side wall of the first body 10 is provided with a slide groove 24 connected to the socket 20. The sliding body 22 passes through the slide groove 24 and is fixedly connected to the plug rod 21. The side wall of the first body 10 is also provided with a positioning groove 23 connected to the slide groove 24. The wall surface of the sliding body 22 is provided with a thrust piece, which can be inserted into the positioning groove 23 to limit the sliding of the sliding body 22. The plug rod 21 forms a rectangular rod structure. The socket 20 and the plug rod 21 cooperate with each other. The sliding body 22 is a rectangular block structure. The structure is that the end face of the sliding body 22 is fixedly connected to the side wall of the insertion rod 21. When the sliding body 22 is facing the positioning groove 23, the insertion rod 21 is inserted into the insertion hole 20 of the second main body 11. In this scheme, by hingedly connecting the first main body 10 and the second main body 11, the first main body 10 and the second main body 11 can be flipped to form a herringbone shape, that is, a herringbone ladder. The first main body 10 is a rectangular frame structure. A plurality of pedals are fixedly connected to the inner wall of the first main body 10. A cable can be tied between the first main body 10 and the second main body 11 to limit the maximum angle at which the first main body 10 and the second main body 11 flip over. When the first main body 10 needs to be leaned against the wall for use, the second main body 11 is flipped to the top of the first main body 10, and the insertion rod 21 is pushed into the insertion hole 20 on the wall of the second main body 11. The first main body 10 and the second main body 11 remain in a parallel state, thereby being able to realize the switching between the herringbone ladder and the overlapping ladder, which has more functions, is more practical, and is simple and convenient to operate.

As shown in Figures 3 and 5, the thrust member includes a protrusion 30 and a toggle rod 32. The protrusion 30 is elastically connected to the sliding body 22, and the toggle rod 32 is fixedly connected to the protrusion 30. The protrusion 30 can be inserted into the positioning groove 23 to position the sliding body 22. The wall surface of the sliding body 22 is provided with a translation groove 31, and a spring is provided in the translation groove 31. The protrusion 30 slides in the translation groove 31 and is elastically connected to the sliding body 22 through the spring. The protrusion 30 is adapted to the translation groove 31. The protrusion 30 is a rectangular block and is adapted to the positioning groove 23. The two ends of the spring are fixedly connected to the side wall of the protrusion 30 and the inner wall surface of the sliding body 22 respectively. In this scheme, as a supplement to the above scheme, by pushing the sliding body 22 to slide in the slide groove 24, the insertion rod 21 slides in the insertion hole 20 on the wall of the first body 10 and enters the insertion hole 20 on the wall of the second body 11. The protrusion 30 is pushed by the spring to slide in the translation groove 31 and get stuck in the positioning groove 23, so as to limit the sliding body 22, and then the insertion rod 21 can be fixed in position. The insertion rod 21 acts as a reinforcing rib between the first body 10 and the second body 11 to limit the relative rotation of the first body 10 and the second body 11. Then, after the first body 10 and the second body 11 switch their shapes, the overall strength of the lap ladder is high, the shape is stable, and it is not easy to loosen. When the first body 10 and the second body 11 are folded and stored, the toggle rod 32 is pushed to drive the protrusion 30 to slide out of the positioning groove 23, which is convenient for removal.

Working principle: The first body 10 and the second body 11 are hinged, and the first body 10 and the second body 11 can be turned over to form a herringbone shape, that is, a herringbone ladder. The first body 10 is a rectangular frame structure, and the inner wall of the first body 10 is fixedly connected with a plurality of pedals. A cable can be tied between the first body 10 and the second body 11 to limit the maximum angle of the first body 10 and the second body 11 when the first body 10 needs to be leaned against the wall for use, and the second body 11 is turned over to the top of the first body 10, and the sliding body 22 is pushed on the slide. The rod 21 slides in the slot 24, and the insertion rod 21 slides in the socket 20 on the wall of the first body 10 and enters the socket 20 on the wall of the second body 11. The protrusion 30 is pushed by the spring to slide in the translation slot 31 and get stuck in the positioning slot 23, so as to limit the sliding body 22, so that the insertion rod 21 can be fixed in position, and the insertion rod 21 acts as a reinforcing rib between the first body 10 and the second body 11 to limit the relative rotation of the first body 10 and the second body 11. The first body 10 and the second body 11 can be placed against the wall for use.
