Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 This utility model provides a technical solution: an elevator interior wall cleaning device, including a first mounting plate 1 and a second mounting plate 3. The second mounting plate 3 is located on top of the first mounting plate 1. A plurality of cleaning brushes 2 are fixedly connected to the bottom of the first mounting plate 1. A wiping cloth 4 is provided on the top of the second mounting plate 3. A Velcro fuzzy surface 5 is fixedly connected to the bottom of the wiping cloth 4. A Velcro barbed surface 6 is fixedly connected to the top of the second mounting plate 3. The Velcro fuzzy surface 5 and the Velcro barbed surface 6 are attached to each other. Two second connecting plates 8 are fixedly connected between the first mounting plate 1 and the second mounting plate 3. A round tube 10 is movably connected between the two second connecting plates 8. A first connecting plate 7 is fixedly connected to the left side of the round tube 10. A damping shaft 9 is rotatably connected to the first connecting plate 7. The two ends of the damping shaft 9 are fixedly passed through the adjacent second connecting plates 8.

[0029] A handle 11 is movably inserted into the right end of the round tube 10. An anti-slip sleeve 12 is fixedly fitted on the outer edge of the handle 11. A hanging ring 13 is fixedly connected to the right end of the handle 11. A threaded tube 16 is threadedly connected to the outer edge of the round tube 10. An external thread is provided on the outer edge of the round tube 10, and the external thread matches the threaded tube 16. Several expansion joints 14 are provided on the outer edge of the round tube 10 near the right end. Several inclined blocks 15 are fixedly connected to the outer edge of the round tube 10 near the right end. The inner wall of the threaded tube 16 fits against the inclined blocks 15. Several anti-slip strips 17 are fixedly connected to the outer edge of the threaded tube 16. The several anti-slip strips 17 are arranged in a ring array.

[0030] Working Principle: This utility model discloses an elevator interior wall cleaning device. During use, when it is necessary to extend or shorten the length of the handle 11 and the round tube 10, the round tube 10 is held and the threaded tube 16 is rotated. The threaded tube 16 moves under the action of the thread and moves away from the inclined block 15, thereby releasing the fixation of the handle 11. Then, the handle 11 is moved relative to the round tube 10. After the total length of the handle 11 and the round tube 10 is adjusted to a suitable length, the round tube 10 is held and the threaded tube 16 is rotated. The threaded tube 16 moves under the action of the thread and moves towards the inclined block 15. Under the action of the inclined block 15 and the expansion joint 14, when the threaded tube 16 moves towards the inclined block 15, the right end of the round tube 10 retracts inward, thereby fixing the handle 11 in the inner cavity of the round tube 10. This completes the length adjustment of the handle 11 and the round tube 10, making it easier for workers to wipe the higher parts and thus facilitating the comprehensive cleaning of the elevator interior wall.

[0031] When cleaning the elevator interior, a dry cloth 4 is fixed to the second mounting plate 3 by the interlocking of the Velcro loop side 5 and the Velcro barbed side 6. Then, the cleaning brush 2 is wetted by the moving device. After that, the first mounting plate 1 and the second mounting plate 3 are moved by the handle 11, which drives the cleaning brush 2 to scrub the elevator interior. After scrubbing, the handle 11 is flipped so that the cloth 4 is in contact with the elevator interior and the water is wiped dry to avoid water residue, thus ensuring the cleaning effect.
