Abstract
Description
Technical Field
[0001] The present application relates to the technical field of fire doors, and in particular to a cruise ship cabin fire door. Background Art
[0002] Cruise ship cabin fire doors are doors specially designed for fire safety. They are usually used to separate different areas inside the cruise ship to prevent the spread of fire and ensure the safety of passengers and crew. In the event of a fire, these devices can quickly close the door to ensure that the fire area is separated from other areas.
[0003] Most cruise ship cabin fire doors are equipped with automatic closing devices, which close the fire doors electrically or hydraulically. However, the closing process is mostly a one-sided closing method in which the door is pushed from one side to the other. This closing method is slow, and if the fire is on the opposite side of the fire door, the fire and smoke may be blown by the wind in the closing direction of the fire door, thereby delaying the closing time and may even affect the effectiveness of the closing. Utility Model Content
[0004] In view of this, the purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a cruise ship cabin fire door to solve the problems existing in the prior art.
[0005] To achieve the above objectives, the utility model provides a cruise ship cabin fire door, comprising a cabin body, wherein a first nesting frame and a second nesting frame are fixedly connected to the inner side of the cabin body, a first door is slidably connected to the inner surface of the first nesting frame, a second door is slidably connected to the inner surface of the second nesting frame, door handles are provided on the outer surfaces of the first door and the second door, and a driving mechanism for simultaneously closing the first door and the second door is provided inside the cabin body.
[0006] Preferably, the driving mechanism includes an electric push rod fixedly installed on the inner side of the cabin, the output end of the electric push rod is fixedly connected to a concave plate, and an inner plate shaft is fixedly penetrated through the inner side of the concave plate. The driving mechanism can push and pull the first door and the second door at the same time, so that the two doors move in opposite directions, thereby opening or closing the fire door composed of the two doors.
[0007] Preferably, the outer surface of the inner shaft of the plate is rotatably connected to a swing frame, the inner side of the cabin body is fixedly connected to a central shaft, and the outer surface of the central shaft is rotatably connected to the inner surface of the swing frame.
[0008] Preferably, a bottom shaft is fixedly penetrated through the bottom of the swing frame, an outer surface of the bottom shaft is rotatably connected to a first swing bar, a first fixed shaft is fixedly connected to the inner side of the first door, and an outer surface of the first fixed shaft is rotatably connected to an end of the first swing bar away from the bottom shaft.
[0009] Preferably, the top of the swing frame is rotatably connected to a frame top shaft, and the outer surface of the frame top shaft is rotatably connected to a second swing bar.
[0010] Preferably, a second fixed shaft is fixedly connected to the inner side of the second door, and an outer surface of the second fixed shaft is rotatably connected to an end of the second swing bar away from the frame top shaft.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The cruise ship cabin fire door, compared with the single-sided oblique push-pull closing process, the fire door in the present application is closed by two doors approaching and touching each other, and its closing speed is faster, and the wind direction in the fire and smoke has less impact on the fire door, and the situation of reverse closing of the fire door will basically not occur, which greatly improves the closing effectiveness of the fire door.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0020] See also Figure 1-4 A cruise ship cabin fire door comprises a cabin body 1, a first nesting frame 2 and a second nesting frame 3 are respectively fixedly connected to the inner side of the cabin body 1, a first door 4 is slidably connected to the inner surface of the first nesting frame 2, a second door 5 is slidably connected to the inner surface of the second nesting frame 3, door handles 6 are arranged on the outer surfaces of the first door 4 and the second door 5, and a driving mechanism for closing the first door 4 and the second door 5 at the same time is arranged inside the cabin body 1.
[0021] Through the above technical solution, when the device is in use, the driving mechanism can make the first door 4 and the second door 5 approach each other, so that the two doors can be moved out of the first nesting frame 2 and the second nesting frame 3 respectively. When the two doors are in contact, the fire door composed of the two doors is closed. Compared with the fire door closed by pushing and pulling on one side, its closing speed is faster and is less affected by wind direction. When the electric push rod 7 fails, it can be closed manually by the door handle 6.
[0022] Specifically, the driving mechanism includes an electric push rod 7 fixedly installed on the inner side of the cabin body 1 , the output end of the electric push rod 7 is fixedly connected to a concave plate 8 , and an inner plate shaft 9 is fixedly penetrated through the inner side of the concave plate 8 .
[0023] Through the above technical solution, the electric push rod 7 can move the concave plate 8 after being pushed, and at the same time, the swing frame 10 can rotate along the inner plate axis 9 in the concave plate 8.
[0024] Specifically, the outer surface of the inner plate shaft 9 is rotatably connected to a swing frame 10 , the inner side of the cabin body 1 is fixedly connected to a central shaft 11 , and the outer surface of the central shaft 11 is rotatably connected to the inner surface of the swing frame 10 .
[0025] Through the above technical solution, the swing frame 10 will rotate along the central axis 11 after being pushed, and at the same time, the bottom end of the swing frame 10 will push the first swing bar 13 through the frame bottom shaft 12.
[0026] Specifically, a bottom shaft 12 is fixedly provided on the bottom of the swing frame 10, and a first swing bar 13 is rotatably connected to the outer surface of the bottom shaft 12. A first fixed shaft 14 is fixedly connected to the inner side of the first door 4, and an outer surface of the first fixed shaft 14 is rotatably connected to an end of the first swing bar 13 away from the bottom shaft 12.
[0027] Through the above technical solution, after the first swing bar 13 is pushed by the frame bottom shaft 12 and the swing frame 10, the first swing bar 13 can rotate along the first fixed axis 14, and at the same time, the first door 4 is pushed and pulled.
[0028] Specifically, the top of the swing frame 10 is rotatably connected to a frame top shaft 15 , and the outer surface of the frame top shaft 15 is rotatably connected to a second swing bar 16 .
[0029] Through the above technical solution, during the deflection process of the swing frame 10, the top of the swing frame 10 will push and pull the second swing bar 16 through the frame top shaft 15.
[0030] Specifically, a second fixed shaft 17 is fixedly connected to the inner side of the second door 5 , and an outer surface of the second fixed shaft 17 is rotatably connected to an end of the second swing bar 16 away from the frame top shaft 15 .
[0031] Through the above technical solution, the second swing bar 16 can rotate along the second fixed axis 17 after being pushed and pulled, and at the same time, the second door 5 is pushed and pulled through the second fixed axis 17 to open or close the fire door.
[0032] Working principle: When the device is in use, the first door 4 and the second door 5 form a fire door. When the fire door is quickly closed, the electric push rod 7 needs to be opened to pull back the concave plate 8. At this time, the swing frame 10 will rotate along the inner axis 9 of the plate, and pull the swing frame 10 to rotate along the central axis 11. During the rotation process, the swing frame 10 will drive the first swing bar 13 through the bottom axis 12 at its bottom, so that the first swing bar 13 rotates along the first fixed axis 14 while pulling back the first fixed axis 14, and finally the first door 4 is moved out of the first nesting frame 2. At the same time, when the swing frame 10 rotates, the top axis 15 at its top is synchronized with it. Move, and let the second swing bar 16 rotate along the top axis 15 while pulling the second swing bar 16. At this time, the second swing bar 16 rotates slightly along the second fixed axis 17 while pulling it, and finally the second door 5 can be pulled out from the second nesting frame 3, and the first door 4 and the second door 5 will be close to each other on the same plane until they touch, and the fire door is closed after the two doors touch. Compared with the unilateral oblique push-pull closing process, the fire door in the present application has a faster closing speed, and the wind direction in the fire and smoke has less influence on the fire door, and the situation of reverse closing of the fire door will basically not occur, which greatly improves the closing effectiveness of the fire door.
