[0025] 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. Example

[0026] like Figures 1-4 As shown, the present invention proposes a safety warning device for an elevator, comprising a movable plate 1 and a warning box 8. A storage box 4 is fixedly connected to the top of the movable plate 1, and the storage box 4 and the warning box 8 are movably connected. A rain cover 2 is fixedly connected to the outside of the warning box 8, and a first fixed plate 5 is fixedly connected to the outside of the storage box 4. An adjusting motor 3 is fixedly connected to the side of the first fixed plate 5 away from the movable plate 1. An adjusting component is provided on the adjusting motor 3. The adjusting component is used for raising and lowering the warning box 8. The adjusting component includes adjusting gears 7 symmetrically arranged on the adjusting motor 3 and adjusting racks 6 symmetrically arranged on the warning box 8.

[0027] The inner side of the warning box 8 is movably connected to the display belt 18, and the side of the warning box 8 near the rain cover 2 is movably connected to the alarm 13. The warning box 8 is provided with a drive assembly for the alarm 13 and the display belt 18. The drive assembly is used for the reciprocating motion of the alarm 13 and the arc motion of the display belt 18. The drive assembly includes a drive motor 9, a chain 11 and a bidirectional threaded rod 12.

[0028] The output end of the adjusting motor 3, which extends to the inside of the storage box 4, is fixedly connected to the first fixing plate 5. The first fixing plate 5 is rotatably connected to the storage box 4, and the two adjusting gears 7 are fixedly connected to the first fixing plate 5.

[0029] The two adjusting racks 6 are fixedly connected to the warning box 8, and the adjusting racks 6 mesh with the first fixed plate 5;

[0030] The inner side of the storage box 4 is symmetrically fixedly connected with guide plates 15, and the inner sides of the two guide plates 15 are symmetrically rotatably connected with guide wheels 16, which are slidably connected to the warning box 8.

[0031] In this embodiment, when no emergency occurs, the device is deployed to the relevant location via the movable plate 1. Then, by controlling the rotation of the regulating motor 3, the rotation of the regulating motor 3 drives the rotation of the first fixed plate 5, which in turn drives the rotation of the regulating gear 7. The rotation of the regulating gear 7 drives the rotation of the two regulating gears 7 fixedly connected to it, and the rotation of the two regulating gears 7 drives the movement of the two regulating racks 6 meshing with them. The movement of the two regulating racks 6 allows the warning box 8 to extend out of the storage box 4. The height of the warning box 8 is adjusted by the rotation of the regulating racks 6. During the movement of the regulating racks 6, the movement of the storage box 4 is guided by the guide wheels 16 symmetrically arranged on the inner side of the guide plate 15. Subsequently, the relevant safety measures and other reminders set on the display belt 18 are displayed. In the above process, the movable design allows the warning box 8 to be easily moved between different locations, adapting to various working environments and site requirements. At the same time, the height of the warning box 8 can be freely adjusted by the regulating motor 3. The height adjustment function of the warning box 8 also means that during storage and transportation, it can be adjusted to a suitable height to reduce space occupation and facilitate handling. Example

[0032] like Figures 1-4 As shown, based on Embodiment 1, a second fixing plate 10 is fixedly connected to the side of the warning box 8 near the alarm 13. The second fixing plate 10 is fixedly connected to the drive motor 9. The output end of the drive motor 9 extending to the inside of the warning box 8 is fixedly connected to a first rotating shaft 17. The first rotating shaft 17 is rotatably connected to the warning box 8.

[0033] The inner side of the warning box 8 is rotatably connected to a second rotating shaft 21, and a display belt 18 is sleeved between the second rotating shaft 21 and the first rotating shaft 17.

[0034] The first rotating shaft 17 extends to one end of the outer side of the warning box 8 and is fixedly connected to the first drive gear 19. The side of the warning box 8 near the rain cover 2 is symmetrically fixedly connected to the fixed seat 14, and the two fixed seats 14 are rotatably connected to each other by a bidirectional threaded rod 12.

[0035] The bidirectional threaded rod 12 is threadedly connected to the alarm 13, and the alarm 13 is slidably connected to the warning box 8. The bidirectional threaded rod 12 extends to the outside of the fixed seat 14 and is fixedly connected to the second drive gear 20 at one end near the first drive gear 19. The first drive gear 19 and the second drive gear 20 are together fitted with a chain 11.

[0036] In this embodiment, when an emergency occurs, personnel inside the elevator can control the rotation of the drive motor 9. The rotation of the drive motor 9 drives the rotation of the first rotating shaft 17, which in turn drives the movement of the display belt 18. Simultaneously, the second rotating shaft 21 tightens the movement of the display belt 18, allowing the safety message on the display belt 18 to be displayed in a circular motion. Subsequently, the movement of the first rotating shaft 17 drives the rotation of the first drive gear 19, which in turn drives the movement of the chain 11. The movement of the chain 11 drives the rotation of the second drive gear 20, which in turn drives the rotation of the bidirectional threaded rod 12. The rotation of the bidirectional threaded rod 12 causes the alarm 13, which is threadedly connected to it, to reciprocate. At this time, the alarm light and alarm horn on the alarm 13 start working to alert relevant personnel. In the above process, when an emergency occurs, the drive motor 9 can quickly respond to the emergency, driving the movement of the alarm 13 and the display belt 18 without manual intervention or additional preparation time. This allows emergency response measures to be displayed and executed immediately, buying valuable time for rescue and escape.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
