Description

Technical Field

[0001] This utility model relates to the field of elevator ceiling technology, specifically to an elevator ceiling structure. Background Technology

[0002] With the acceleration of urbanization and the increasing number of high-rise buildings, elevators, as an important tool for vertical transportation, are receiving increasing attention for their safety and functionality. Elevator ceilings are designed to match the internal dimensions of the car. During elevator operation, various reasons, such as equipment failure or power outages, may lead to passengers being trapped inside the car.

[0003] Traditional elevator ceiling structures have many shortcomings in dealing with this situation. For example, some ceilings compromise their escape function for aesthetic reasons. In an emergency, such as when people are trapped, the ceiling or light shield is difficult to remove, making it difficult for trapped people to escape from the ceiling, and they can only wait for rescue personnel. Some escape covers are driven by electric mechanisms. When there is a power outage or the electric mechanism is damaged, the escape cover will not be able to open, thus failing to guarantee that trapped people can escape from the ceiling. At the same time, some escape covers may be accidentally opened, which may result in people being injured by falling objects. Therefore, we need to propose an elevator ceiling structure. Utility Model Content

[0004] The purpose of this utility model is to provide an elevator ceiling structure that involves attaching a metal clip between the ceiling panel and the escape cover, then sliding a metal side column to the rear of the clip, and rotating a rotating disk to prevent the metal side column from moving into the rotating disk. When the escape cover needs to be opened, the rotating disk is rotated to the desired position, and then a magnet inside the placement box pulls the metal side column into the rotating disk. At the same time, rotating the rotating disk moves the metal side column away from the clip, and finally the magnet moves the metal clip completely into the escape cover, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator ceiling structure, including a mounting frame and a ceiling panel disposed inside the mounting frame, wherein an escape cover is rotatably disposed on the side of the ceiling panel;

[0006] The ceiling panel and the escape cover are provided with a connecting component that uses a mechanical structure to prevent accidental opening of the escape cover;

[0007] The connecting assembly includes a rotating disk, metal side pillars, metal locking pillars, and a positioning module.

[0023] 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.

[0024] This utility model provides: an elevator ceiling structure, such as... Figure 1-4 As shown, the system includes an installation frame 1 and a ceiling panel 2 located inside the installation frame 1. An escape cover 5 is rotatably mounted on the side of the ceiling panel 2. Neither the ceiling panel 2 nor the escape cover 5 is made of metal, and the escape cover 5 is made of transparent material, which makes it easy for people to see the positions of the metal side pillars 16 and metal locking pillars 18 inside the escape cover 5. At the same time, when the elevator loses power, the escape cover 5 will let light through, making it easier for people to find the location of the escape cover 5 and then open the escape cover 5 to escape.

[0025] Preferably, a connecting assembly with a mechanical structure is provided between the ceiling panel 2 and the escape cover 5 to prevent accidental opening of the escape cover 5. The connecting assembly includes a rotating disk 13, metal side pillars 16, metal locking posts 18, and a positioning module. The rotating disk 13 is rotatably disposed inside the escape cover 5, the metal side pillars 16 are slidably disposed inside the rotating disk 13, and the metal locking posts 18 are slidably disposed inside the ceiling panel 2 and the escape cover 5. The rotating disk 13 has a placement groove 14 corresponding to the metal side pillars 16, and the escape cover 5 has a sliding groove 17 corresponding to the metal locking posts 18. The placement groove 14 and the sliding groove 17 are connected. The ceiling panel 2 has a locking groove 19 corresponding to the metal locking posts 18 on the side closest to the escape cover 5. The sliding groove 17 and the locking groove 19 are connected. The 9-connection configuration allows the escape cover 5 to be locked when the metal side column 16 is moved into the placement slot 14 inside the rotating disk 13. Then, the metal locking column 18 is moved between the sliding slot 17 and the locking slot 19. At this time, the ceiling panel 2 and the escape cover 5 are locked by the metal locking column 18. Then, the metal side column 16 is moved into the sliding slot 17, thus blocking the metal locking column 18. Then, the rotating disk 13 is rotated to move the placement slot 14 away from the metal side column 16. At this time, the metal side column 16 will be completely locked inside the sliding slot 17, thus ensuring the stability of the locking of the ceiling panel 2 and the escape cover 5. At the same time, it prevents people from accidentally opening the escape cover 5 when placing long items inside the elevator, thereby preventing people from being injured by accidental opening of the escape cover 5.

[0026] In addition, the positioning module includes a first spring plunger 9 and a mounting hole. The first spring plunger 9 is located on one side of the escape cover 5, and the mounting hole corresponds to the first spring plunger 9. The mounting hole is located inside the ceiling panel 2. When the escape cover 5 is opened and closed again, the first spring plunger 9 will be inserted into the mounting hole inside the ceiling panel 2. At this time, the snap-fit ​​groove 19 on the side of the ceiling panel 2 is connected to the metal side post 16 on the side of the escape cover 5, so that the staff can operate the metal side post 16 and the metal snap-fit ​​post 18 to lock the ceiling panel 2 and the escape cover 5, avoiding the need for the staff to manually support the escape cover 5 to lock it.

[0027] Furthermore, an operation button 6 is fixedly installed on one side of the rotating disk 13. One end of the operation button 6 rotates through the escape cover 5. A pointer is installed on the side of the operation button 6, and an indicator strip is installed on the inside of the escape cover 5 and on the side of the operation button 6. By rotating the operation button 6, the rotating disk 13 is driven to rotate. When the pointer on the surface of the operation button 6 points to the indicator strip, the placement groove 14 is connected to the sliding groove 17, so that people can intuitively see the position of the rotating disk 13. At the same time, the operation button 6 is located on the side of the ceiling panel 2 close to the inside of the elevator, so as to ensure that people can operate the operation button 6 to drive the rotating disk 13 to rotate.

[0028] Furthermore, the ceiling panel 2 has several sets of lighting structures 4 on its inner side, and ventilation openings 3 on its side. A dustproof component is provided on the side of the ceiling panel 2 away from the lighting structures 4 to prevent dust from entering the ventilation openings 3. The dustproof component includes a placement frame 10, a filter plate 15, protrusions 22, and a limiting module. The placement frame 10 is bolted to the side of the ceiling panel 2, and the protrusions 22 are symmetrically arranged on both sides of the filter plate 15. The placement frame 10 has slots 11 corresponding to the filter plate 15 and protrusions 22 inside. A maintenance cover 12 is provided on the side of the ceiling panel 2 away from the elevator interior to facilitate maintenance of the lighting structures 4. The filter plate 15 is inserted into the slots 11 via the protrusions 22, ensuring the accuracy of the filter plate 15's insertion position. This allows the filter plate 15 to block the ventilation openings 3, preventing dust from entering the elevator interior through the ventilation openings 3 and causing a decrease in air quality inside the elevator.

[0029] It is worth noting that the limiting module includes an extension plate 20 and a second spring plunger 23. The second spring plunger 23 is fixedly disposed on the upper surface of the protrusion 22, and the extension plate 20 is fixedly disposed on both sides of the placement frame 10. The two sets of extension plates 20 have positioning holes 21 corresponding to the second spring plunger 23 on their corresponding surfaces. When the filter plate 15 is inserted into the slot 11, the second spring plunger 23 will be inserted into the positioning hole 21 on the side of the extension plate 20, thereby positioning the filter plate 15 inside the placement frame 10, thus ensuring the stability of the filter plate 15 after insertion.

[0030] Specifically, a placement box 7 is bolted to the side of the ceiling panel 2, and an insertion cover 8 is inserted into the side of the placement box 7. A magnet is placed inside the placement box 7. The magnet is placed inside the placement box 7, and then the placement box 7 is blocked by the insertion cover 8. When the magnet is needed, the insertion cover 8 is pulled out and the magnet is taken out. Since the metal side column 16 and the metal locking column 18 are both made of metal, it is ensured that the magnet can pull the metal side column 16 into the rotating disk 13. At the same time, rotating the rotating disk 13 moves the metal side column 16 away from the metal locking column 18. Finally, the magnet moves the metal locking column 18 completely into the escape cover 5. At this time, pulling the escape cover 5 can open the escape cover 5, thereby avoiding the inability to open the escape cover 5 to escape due to power outages or damage to the locking structure.

[0031] 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.
