[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a special insulating ladder for power grids that is easy to store, including a leg 1 and a leg 2, a rotating plate 4 is provided in the leg 1, a rotating plate 2 is provided in the leg 2, a groove 3 is provided in the leg 1, a fixing rod 2 7 is rotatably connected in the leg 1, and a fixing rod 1 6 is rotatably connected in the leg 2;

[0019] The rotating plate 1 4 is connected to the outside of the fixing rod 2 7, and the rotating plate 2 5 is connected to the outside of the fixing rod 1 6. By setting the fixing rod 1 6 and the fixing rod 2 7, when the supporting legs 1 and 2 2 are extended outward, the rotating plate 1 4 will rotate around the fixing rod 2 7, and the rotating plate 2 5 will rotate around the fixing rod 1 6, so that the fixing rod 1 6 and the fixing rod 2 7 play a certain role in limiting the rotation of the rotating plate 1 4 and the rotating plate 2 5.

[0020] A guide rod 10 is rotatably connected inside the rotating plate 1 4, and the guide rod 10 is connected to the outside of the rotating plate 2 5. A ratchet 11 is connected to the outside of the guide rod 10. An auxiliary rod 13 is connected to the side of the rotating plate 1 4. A clamping block 8 is provided on the rotating plate 1 4, and a clamping slot 9 is provided in the rotating plate 2 5. By setting the clamping block 8 and the clamping slot 9, when the rotating plate 1 4 and the rotating plate 2 5 are stored, the rotating plate 2 5 will rotate on the surface of the rotating plate 1 4, and the clamping block 8 above the rotating plate 1 4 will be clamped into the clamping block 8, so that the rotating plate 1 4 and the rotating plate 2 5 can completely overlap, avoiding the rotating plate 1 4 and the rotating plate 2 5 from getting stuck when being stored;

[0021] The auxiliary rod 13 is externally rotatably connected with the ratchet 12, and the auxiliary rod 13 is externally connected with a coil spring 14. The ratchet 12 overlaps with the ratchet wheel 11, and the ratchet 12 is connected with the rotating plate 4 through the coil spring 14. By setting the coil spring 14, when the ratchet 12 rotates under the rotation force, the ratchet 12 will drive the coil spring 14 to deform, so that the coil spring 14 plays a certain supporting role in the rotation of the ratchet 12. When the ratchet 12 loses resistance, it will be reset through the coil spring 14;

[0022] A slide groove 15 is provided in the rotating plate 4, and a strap 16 is slidably connected in the slide groove 15. The strap 16 overlaps the ratchet bar 12, and a mounting block 17 is connected to the strap 16. A bolt 18 is provided in the mounting block 17, and the mounting block 17 is connected to the rotating plate 4 through the bolt 18. By setting the slide groove 15, when the strap 16 is subjected to thrust, the strap 16 will slide in the slide groove 15, so that the slide groove 15 plays a certain guiding role in the movement of the strap 16.

[0023] The working principle of the utility model is:

[0024] When the insulating ladder is in use, the support leg 2 can be pulled. When the support leg 2 moves to the appropriate position, the rotating plate 4 will rotate around the fixed rod 27, and the rotating plate 25 will rotate around the fixed rod 6. The rotating plate 25 will rotate in the rotating plate 4 along with the guide rod 10. When the guide rod 10 rotates, it will drive the ratchet 11 to move on the surface of the ratchet bar 12. When the rotating plate 4 and the rotating plate 25 are in a horizontal state, the ratchet bar 12 is reset by the action of the coil spring 14. The reset ratchet bar 12 will overlap with the ratchet bar 11, and then drive the strap 16 to slide in the slide groove 15. When the strap 16 overlaps with the ratchet bar 12, the mounting block 17 above the strap 16 is connected to the rotating plate 4 by the bolt 18. When the support leg 1 and the leg 2 are stored, the rotating plate 4 will be hidden in the groove 3, and the card block 8 above the rotating plate 4 will be hidden in the card groove 9.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
