Description

Technical Field

[0001] This utility model relates to the field of elevator safety technology, and in particular to an elevator hall door that can be manually opened after a power outage. Background Technology

[0002] An elevator is a vertical transportation device used to move people and goods between different floors. Driven by an electric motor, it uses steel cables and a hydraulic system to move the elevator car along a set of vertical tracks within a building. The basic components of an elevator include the elevator car, drive system, control system, safety equipment, and doors. An elevator lobby is the area connecting the elevator shaft to other floors of a building. It is typically located at the elevator entrance on each floor. The elevator lobby mainly includes the elevator entrance door and the front wall of the elevator shaft, serving as the passageway for passengers to enter and exit the elevator. Inside the elevator lobby, passengers can wait for the elevator to arrive and select their destination floor.

[0003] In existing technologies, some elevator hall doors typically consist of a door frame, door leaf, drive mechanism, locking device, switching device, and safety device. The door frame and door leaf are the basic structure of the elevator hall door, used to separate the elevator car and the elevator hall to ensure safety. The drive mechanism usually consists of an electric motor and a transmission system, used to automatically open and close the elevator hall door. The locking device is used to ensure that the door remains locked when it is not normally opened, preventing the door from being opened accidentally. The switching device controls the opening and closing operation of the elevator hall door, including buttons, sensors, etc. The safety device includes functions such as door collision detection and emergency unlocking to ensure the safety of passengers and personnel.

[0004] However, in actual use, some elevator hall doors usually rely on the mechanical structure driven by electric motors and lack an effective manual release mechanism. Although they can provide a convenient operating experience in daily use, they are vulnerable and powerless in emergency situations. Passengers may face anxiety and panic when they cannot open the hall door during power outages or elevator malfunctions, which may even affect their lives. The manual opening function of existing elevator hall doors often requires complicated operating steps, which are difficult for ordinary users to master, further exacerbating the risks in emergency situations. In response to the above problems, an elevator hall door that can be manually opened after a power outage is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an elevator hall door that can be manually opened after a power outage, aiming to improve the problem that some devices in the prior art cannot be manually opened.

An emergency opening mechanism is fixedly connected inside the sliding elevator hall door, and a protective mechanism is fixedly connected inside one of the fixed walls.

[0008] The emergency opening mechanism includes a fixed connecting block, which is externally fixedly connected to the inside of the sliding elevator hall door. The fixed connecting block has an opening hole rotatably connected inside. Two rotating sliding wheels are fixedly connected to one side of the fixed connecting block. One of the rotating sliding wheels is externally fixedly connected to a transmission component. A second fixed connecting plate is fixedly connected to the top of the sliding elevator hall door. A limit sliding wheel is rotatably connected to the outside of the second fixed connecting plate. A locking component is fixedly connected to the top of the sliding elevator hall door.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The transmission assembly includes a transmission connecting plate, which is fixedly connected to the outside of one of the rotating pulleys. A transmission connecting rod is rotatably connected to the outside of the transmission connecting plate. A limiting rotating plate is rotatably connected to the outside of the transmission connecting rod. A first fixed connecting plate is rotatably connected to the outside of the limiting rotating plate.

[0013] As a further description of the above technical solution:

[0014] The locking assembly includes an I-beam connecting plate, the bottom of which is slidably connected to the top of the sliding elevator hall door, and a limit box is fixedly connected to the outside of the I-beam connecting plate.

[0015] As a further description of the above technical solution:

[0016] The buffer assembly includes a vertical connecting plate, which is externally fixedly connected to one end of the plurality of connecting telescopic columns, and a buffer protective pad is externally fixedly connected to the vertical connecting plate.

[0017] As a further description of the above technical solution:

[0018] The cleaning assembly includes sliding connecting plates. The two sliding connecting plates are slidably connected to the upper and lower ends of the interior of the fixed wall on the side closest to each other, i.e. the side furthest from the two sliding connecting plates. Multiple vertical connecting columns are detachably connected to the side closest to each other, i.e. the side furthest from the two sliding connecting plates. Cleaning brushes are fixedly connected to the outside of the vertical connecting columns.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, by inserting the tool into the opening hole and rotating it, the rotating sliding wheel rotates and drives the transmission connecting plate, causing the transmission connecting rod to push upward, thereby limiting the rotating plate to move upward and releasing the restriction of the rotating plate inside the limiting box. This allows the sliding elevator hall door to be opened manually, ensuring personnel safety and improving the reliability of the elevator system.

[0029] 2. In this utility model, when the sliding elevator hall door opens and slides into the wall, the cleaning brush inside the wall is fixed by the sliding force to clean the inside of the sliding elevator hall door. When it reaches the bottom, the inside of the sliding elevator hall door first touches the buffer protective pad and squeezes the connecting telescopic column and buffer spring, thus achieving a buffer protection effect. The overall cooperation improves the service life of the sliding elevator hall door. Attached Figure Description

[0036] 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.

[0037] Reference Figures 1 to 3This utility model provides an embodiment of an elevator hall door that can be manually opened after a power outage. It includes two fixed walls 1, both of which are cuboid structures providing solid support for the elevator hall door system. A sliding elevator hall door 2 is slidably connected to the adjacent side (the outer side away from the two fixed walls 1). The sliding elevator hall door 2 is rectangular and can slide horizontally along the adjacent side of the two fixed walls 1. Its movement trajectory is guided by components such as an I-beam connecting plate 3. The top of the sliding elevator hall door 2 is fixedly connected to the bottom of a first fixed connecting plate 5, and the outer side of the first fixed connecting plate 5 is slidably connected to... An emergency opening mechanism is fixedly connected inside the sliding elevator hall door 2 on the outside of the I-beam connecting plate 3. The emergency opening mechanism includes a fixed connecting block 8, which is rectangular in shape. The fixed connecting block 8 is fixedly connected to the inside of the sliding elevator hall door 2. An opening hole 9 is rotatably connected inside the fixed connecting block 8. A circular opening hole 9 is provided for connecting an external opening tool. Two rotating sliding wheels 10 are fixedly connected to one side of the fixed connecting block 8. The rotating sliding wheels 10 are cylindrical, which allows the rotating sliding wheels 10 to rotate flexibly and roll on a specific track, providing auxiliary motion for the operation of the emergency opening mechanism.

[0038] One of the rotating pulleys 10 is externally fixedly connected to a transmission component, which includes a transmission connecting plate 11. The transmission connecting plate 11 is rectangular and rotates together with the rotating pulley 10 connected to it. Its direction of movement is related to the rotation direction of the rotating pulley 10. The transmission connecting plate 11 is externally fixedly connected to the outside of one of the rotating pulleys 10. The transmission connecting rod 7 is rotatably connected to the outside of the transmission connecting plate 11. The transmission connecting rod 7 is long and plate-shaped. The other end of the transmission connecting rod 7 is rotatably connected to a limiting rotating plate 6 via a pin. The limiting rotating plate 6 is rectangular and is also rotatably connected to a first fixed connecting plate 5 via a pin, realizing linkage with the top of the sliding elevator hall door 2. The first fixed connecting plate 5 is rotatably connected to the outside of the limiting rotating plate 6.

[0039] A second fixed connecting plate 12 is fixedly connected to the top of the sliding elevator hall door 2. A limiting sliding wheel 13 is rotatably connected to the outside of the second fixed connecting plate 12. A locking assembly is fixedly connected to the top of the sliding elevator hall door 2. The locking assembly includes an I-shaped connecting plate 3. The I-shaped connecting plate 3 has an "I"-shaped structure. The bottom of the I-shaped connecting plate 3 is slidably connected to the top of the sliding elevator hall door 2 through a slide rail, providing guidance for the sliding of the sliding elevator hall door 2. The bottom of the I-shaped connecting plate 3 is slidably connected to the top of the sliding elevator hall door 2. A limiting box 4 is fixedly connected to the outside of the I-shaped connecting plate 3. The limiting box 4 has a cuboid shape and is used to limit the rotation of the limiting rotating plate 6. The inside of the limiting box 4 is slidably connected to the outside of the limiting rotating plate 6, and the outside of the limiting rotating plate 6 is rotatably connected to the outside of the I-shaped connecting plate 3. When the emergency opening mechanism is activated, the rotating sliding wheel 10 drives the transmission assembly to move, so that the limiting rotating plate 6 overcomes the limitation of the limiting box 4 and rotates to a specific angle, releasing the lock on the sliding elevator hall door 2 and realizing manual opening.

[0040] Reference Figure 1 and Figure 4 One of the fixed walls 1 is internally connected to a protective mechanism, which includes multiple connecting telescopic columns 17. The connecting telescopic columns 17 are cylindrical. One end of the connecting telescopic column 17 is fixed inside the fixed wall 1, and a buffer spring 18 is sleeved on the outside. The buffer spring 18 is made of high-quality spring steel. When an external force impacts the elevator hall door, the connecting telescopic column 17 can extend and retract inside the fixed wall 1, and the buffer spring 18 absorbs and buffers the impact force by compression and extension. One end of the buffer spring 18 is fixedly connected to the outside of the vertical connecting plate 19, and the other end of the buffer spring 18 is fixedly connected to one side inside the fixed wall 1.

[0041] The other end of the multiple connecting telescopic columns 17 is fixedly connected to a buffer assembly. The buffer assembly includes a vertical connecting plate 19, which is rectangular in shape. The outside of the vertical connecting plate 19 is slidably connected to the inside of one of the fixed walls 1 through a slide rail. Its movement direction is consistent with the telescopic direction of the connecting telescopic columns 17. The outside of the vertical connecting plate 19 is slidably connected to the inside of one of the fixed walls 1. The outside of the buffer protective pad 20 is slidably connected to the inside of one of the fixed walls 1. The outside of the vertical connecting plate 19 is fixedly connected to one end of the multiple connecting telescopic columns 17. The outside of the vertical connecting plate 19 is fixedly connected to the buffer protective pad 20, which is rectangular in shape. When impacted, the buffer protective pad 20 first contacts the external force, and then transmits the force to the connecting telescopic columns 17 and the buffer spring 18 through the vertical connecting plate 19, thus playing a buffering and protective role.

[0042] Cleaning components are slidably connected to the upper and lower ends of the interior of one of the fixed walls 1. The cleaning components include sliding connecting plates 14, which are rectangular plates. The sides of two sliding connecting plates 14 that are close to each other (i.e., the outer sides that are far from the two sliding connecting plates 14) are slidably connected to the upper and lower ends of the interior of the fixed wall 1. Multiple vertical connecting columns 15 are detachably connected to the sides of two sliding connecting plates 14 that are close to each other (i.e., the outer sides that are far from the two sliding connecting plates 14). The vertical connecting columns 15 are cylindrical and connected to the sliding connecting plates 14 by bolts. They can be disassembled and replaced. Cleaning brushes 16 are fixedly connected to the outside of the vertical connecting columns 15. The cleaning brushes 16 are long and narrow. When the sliding elevator hall door 2 slides, the cleaning brushes 16 can contact the surface of the door to clean the dust and debris on the surface of the door and keep the elevator hall door clean.

[0043] Working Principle: Under normal circumstances, the sliding elevator hall door 2 is driven by a motor to slide horizontally between the fixed walls 1. In case of emergencies, such as power failure, and manual opening of the elevator hall door is required, the user can insert an opening tool into the opening hole 9 inside the fixed connecting block 8 and rotate it. The rotational force is transmitted to the transmission connecting plate 11 through the rotating sliding wheel 10, which in turn causes the transmission connecting rod 7 to push upward, pushing the limit rotating plate 6 upward. When the limit rotating plate 6 moves upward, its restriction inside the limit box 4 is released, allowing the sliding elevator hall door 2 to be manually slid open, ensuring personnel safety and improving the reliability of the elevator system.

[0044] Meanwhile, as the elevator hall door 2 slides into the wall, the cleaning brush 16 fixed inside the fixed wall 1 cleans the inside of the elevator hall door 2. The sliding connecting plate 14 can slide out from inside the fixed wall 1, and the cleaning brush 16 can be removed and replaced on the sliding connecting plate 14, which facilitates long-term use. When the sliding elevator hall door slides to the bottom, its inside will first touch the buffer protective pad 20. The buffer protective pad 20 squeezes the connecting telescopic column 17 and the buffer spring 18 to achieve a buffer protection effect, which effectively improves the service life of the sliding elevator hall door 2.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
