[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: an elevator car wall decoration structure, including a car wall body 1, a display frame 2 installed on one side of the car wall body 1, a cover plate 3 rotatably connected to the top of the display frame 2 via a hinge, an upper housing 4 fixed to the bottom of the cover plate 3, a lower housing 5 fixed to the bottom of the display frame 2, a guide groove 6 opened on one side of the lower housing 5, a pull rod 7 slidably connected inside the guide groove 6, a circular plate 8 fixed to the top of the pull rod 7, a lower protrusion 9 fixed to the bottom of the pull rod 7, an upper protrusion 10 slidably connected to one side of the lower protrusion 9, an elastic locking block 11 fixed to the top of the upper protrusion 10, and an elastic locking block 11 cooperating with the elastic locking block 11 inside the upper housing 4. The T-slot 12 is used. By pulling the lever 7, the lower protrusion 9 is moved. The inclined surface of the lower protrusion 9 will generate a pushing force on the upper protrusion 10, pushing the upper protrusion 10 to move towards the upper housing 4. During this process, the two ends of the elastic block 11 will be squeezed by the inclined surface of the T-slot 12. The squeeze will allow it to smoothly enter the interior of the T-slot 12, thereby quickly connecting the display frame 2 and the cover plate 3. Through the above settings, the content replacement in the display frame 2 becomes very convenient, and it can effectively prevent the advertising page from being eroded and damaged by external factors such as dust, stains, and moisture, keeping the displayed content clean and clear, and extending its service life.

[0023] Reference Figure 3 As shown in this embodiment: a first slider 13 is fixed on one side of the lower protrusion 9, and a first groove 14 that cooperates with the first slider 13 is provided inside the lower housing 5. By setting the structure of the first slider 13 and the first groove 14, the movement of the lower protrusion 9 is ensured to be stable and the shaking phenomenon is avoided.

[0024] Reference Figure 3 As shown in this embodiment: one end of the lower protrusion 9 is fixed with a first spring 16, and the other end of the first spring 16 is fixed to the inside of the lower housing 5. Push rods 19 are slidably connected to both sides inside the upper housing 4. One end of the push rod 19 is fixed with a push plate 20. When the advertising page needs to be replaced, the push plate 20 is pushed to drive the push rod 19 to squeeze the two ends of the elastic block 11. At the same time, the rebound force of the first spring 16 is used to push the lower protrusion 9 back to the initial position. The lower protrusion 9 drives the upper protrusion 10 to move, so that it drives the elastic block 11 away from the inside of the T-slot 12, thereby releasing the connection between the display frame 2 and the cover plate 3. The operation is very simple and convenient.

[0025] Reference Figure 3 As shown in this embodiment: both ends of the upper protrusion 10 are fixed with a second slider 17, and the lower housing 5 has a second slide groove 18 that cooperates with the second slider 17. By setting the structure of the second slider 17 and the second slide groove 18, it is ensured that the upper protrusion 10 moves along the prescribed route and prevents deviation.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: an inner plate 21 is provided inside the upper shell 4. U-shaped blocks 22 are fixed at the four corners of one side of the inner plate 21. A circular groove 23 is opened on one side of the U-shaped block 22. A sliding rod 24 is slidably connected inside the circular groove 23. A top plate 25 is fixed to one end of the sliding rod 24. A pressing block 26 is fixed to the end of the sliding rod 24 away from the top plate 25. A second spring 27 is slidably connected to the surface of the sliding rod 24. One end of the second spring 27 is fixed to the top plate 25, and the other end of the second spring 27 is fixed to the sliding rod 24. Through the structure of the top plate 25, the sliding rod 24, the pressing block 26, and the second spring 27, the four corners of the advertising page can be clamped to ensure that the advertising paper or other display content is flatly fixed in the display frame 2, avoiding wrinkles, curling, or loosening of the advertising paper, thereby improving the display effect, making the advertising content clearer and more beautiful, and attracting the attention of passengers.

[0027] Reference Figure 5 As shown in this embodiment: a friction pad 28 is fixed to the bottom of the extrusion block 26. By setting the material of the friction pad 28, the friction between the extrusion block 26 and the advertising paper is significantly increased, preventing the advertising paper from loosening or sliding due to vibration or shaking during elevator operation.

[0028] Working principle: The user moves the lower protrusion 9 by pulling the lever 7. The inclined surface of the lower protrusion 9 generates a pushing force on the upper protrusion 10, pushing the upper protrusion 10 towards the upper housing 4. During this process, the two ends of the elastic locking block 11 are first squeezed by the inclined surface of the T-slot 12, and smoothly enter the interior of the T-slot 12 by the squeezing, thereby quickly realizing the connection between the display frame 2 and the cover plate 3. Through the above settings, the replacement of the content in the display frame 2 becomes very convenient, and it can effectively prevent the advertising page from being corroded and damaged by external factors such as dust, stains, and moisture, keeping the displayed content clean and clear, and extending its service life. By setting the structure of the first slider 13 and the first slide groove 14, it is ensured that the movement of the lower protrusion 9 is in a stable state and avoids shaking. When it is necessary to replace the advertising page, push the push plate 20 to drive the push rod 19 to squeeze the two ends of the elastic locking block 11, while using the The rebound force of the first spring 16 pushes the lower protrusion 9 back to its initial position. The lower protrusion 9 drives the upper protrusion 10 to move, causing the elastic locking block 11 to leave the interior of the T-slot 12, thereby releasing the connection between the display frame 2 and the cover plate 3. The operation is very simple and convenient. By setting the structure of the second slider 17 and the second slide 18, it is ensured that the upper protrusion 10 moves along the prescribed route to prevent deviation. Through the structure of the top plate 25, the sliding rod 24, the squeezing block 26 and the second spring 27, the four corners of the advertising page can be clamped to ensure that the advertising paper or other display content is flat and fixed in the display frame 2, avoiding wrinkles, curling or loosening of the advertising paper, thereby improving the display effect, making the advertising content clearer and more beautiful, and attracting the attention of passengers. By setting the material of the friction pad 28, the friction between the squeezing block 26 and the advertising paper is significantly increased, preventing the advertising paper from loosening or sliding due to vibration or shaking during elevator operation.
