Description

Technical Field

[0001] The utility model relates to the technical field of door and window design, in particular to a door and window assembly with an emergency escape function. Background Art

[0002] Emergency escape doors usually refer to doors used for escape in emergency situations. Such doors are designed to provide fast and safe passages so that people can quickly leave buildings or areas in the event of fire, earthquake, explosion or other emergencies. Most university classrooms have front and back doors, but the front and back doors are relatively narrow. There are generally more students in university classrooms. Once an emergency occurs, the narrow doorways will cause congestion, affecting the escape speed of teachers and students.

[0003] In order to solve the above problems, we propose a door and window assembly with emergency escape function. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and proposes a door and window assembly with an emergency escape function.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a door and window assembly with an emergency escape function, comprising a fixed frame, a left inner wall of the fixed frame being rotatably connected to an emergency door, a left front wall of the emergency door being provided with an opening, a left inner wall of the opening being rotatably connected to a single door, an emergency unlocking device being provided on the front wall of the emergency door, and a baffle being fixedly connected to the right front wall of the fixed frame.

[0006] In the above-mentioned door and window assembly with emergency escape function, the emergency unlocking device includes a rotating rod rotatably connected to the front side wall of the emergency door, the right end of the rotating rod is fixedly connected to a block located between the baffle and the fixed frame, the front side wall of the emergency door is fixedly connected to a fixed block located on the upper side of the rotating rod, a spring is fixedly connected between the fixed block and the upper side wall of the rotating rod, and a handle is provided on the front side wall of the rotating rod.

[0007] In the above-mentioned door and window assembly with emergency escape function, the front side wall of the emergency door is fixedly connected to a fixed plate located on the outside of the emergency unlocking device, the fixed plate is arranged in a C shape, a fixed shaft is fixedly arranged on the upper part of the fixed plate, and a cover plate is rotatably sleeved on the outer side wall of the fixed shaft.

[0008] In the above-mentioned door and window assembly with emergency escape function, a magnetic stripe 1 is fixedly provided on the front side wall at the lower end of the fixing plate, and a magnetic stripe 2 is provided on the rear side wall at the lower end of the cover plate.

[0009] In the above-mentioned door and window assembly with emergency escape function, the front side wall of the single-leaf door is provided with a round head lock, the inner sliding of the single-leaf door is provided with a lock tongue, and the right inner side wall of the opening is provided with a notch matching the lock tongue.

[0010] In the above-mentioned door and window assembly with emergency escape function, the emergency door can rotate clockwise around the fixed frame, and can also rotate counterclockwise around the fixed frame.

[0011] Compared with the existing technology, the advantages of this door and window assembly with emergency escape function are:

[0012] The utility model rotates the stopper out from between the baffle plate and the fixed frame by rotating the handle, and the emergency door can be opened by pushing or pulling the handle. The emergency door is much larger than a single door, so the opening space is larger, which reduces the occurrence of doorway congestion when teachers and students escape.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3 A door and window assembly with an emergency escape function comprises a fixed frame 1, the fixed frame 1 has no lower frame, the fixed frame 1 is fixedly installed on a wall, the left inner wall of the fixed frame 1 is rotatably connected with an emergency door 2, the left front wall of the emergency door 2 is provided with an opening 3, the left inner wall of the opening 3 is rotatably connected with a single door 4, daily opening and closing of the door can be achieved by operating the single door 4, the front wall of the single door 4 is provided with a round head lock 5, the inner sliding wall of the single door 4 is provided with a lock tongue 6, and the right inner wall of the opening 3 is provided with a notch matching the lock tongue 6.

[0019] An emergency unlocking device is provided on the front side wall of the emergency door 2, and the emergency unlocking device is located lower to ensure that people of short stature can operate the emergency unlocking device. A baffle 16 is fixedly connected to the right front side wall of the fixed frame 1, and the left side wall of the baffle 16 is flush with the right inner wall of the fixed frame 1, to ensure that the emergency door 2 can be opened when the emergency door 2 is rotated, that is, the emergency door 2 can be rotated clockwise around the fixed frame 1, and can also be rotated counterclockwise around the fixed frame 1. The emergency unlocking device includes a rotating rod 15 rotatably connected to the front side wall of the emergency door 2, and the right end of the rotating rod 15 is fixedly connected to a block 11 located between the baffle 16 and the fixed frame 1. The side wall is fixedly connected with a fixed block 13 located on the upper side of the rotating rod 15, and a spring 14 is fixedly connected between the fixed block 13 and the upper side wall of the rotating rod 15. The spring 14 pulls the end of the rotating rod 15 upward so that the block 11 is between the baffle 16 and the fixed frame 1. Since the distance between the rotating rod 15 and the emergency door 2 is small, it is inconvenient for personnel to operate the rotating rod 15, so a handle 12 is provided on the front side wall of the rotating rod 15. The distance between the handle 12 and the emergency door 2 is large. By rotating the handle 12 to drive the rotating rod 15 to rotate, the rotating rod 15 drives the block 11 to rotate out from between the baffle 16 and the fixed frame 1, thereby unlocking the emergency door 2 relative to the fixed frame 1.

[0020] The front side wall of the emergency door 2 is fixedly connected to a fixed plate 7 located on the outside of the emergency unlocking device. The fixed plate 7 is arranged in a C shape, that is, the fixed plate 7 surrounds the upper side, lower side and left side of the emergency unlocking device. A fixed shaft 8 is fixedly arranged on the upper part of the fixed plate 7, and a cover plate 9 is rotatably sleeved on the outer wall of the fixed shaft 8. The cover plate 9 and the fixed plate 7 have a certain protective effect on the emergency unlocking device. A magnetic strip 10 is fixedly arranged on the front side wall of the lower end of the fixed plate 7, and a magnetic strip 2 is arranged on the rear side wall of the lower end of the cover plate 9. When the cover plate 9 is in contact with the fixed plate 7, the magnetic strip 10 and the magnetic strip 2 are attracted to each other, so that the cover plate 9 is stabilized on the fixed plate 7. The distance between the cover plate 9 and the emergency door 2 is relatively large. By extending your hand from the right side of the cover plate 9 to this distance, you can pull the cover plate 9 forward to open the cover plate 9.

[0021] The emergency escape process of the utility model is: open the cover plate 9, turn the handle 12 counterclockwise downward, the rotating rod 15 drives the stopper 11 to rotate, and the stopper 11 rotates out from between the baffle 16 and the fixed frame 1. At this time, push the handle 12 backward or pull it forward, the emergency door 2 will rotate around the fixed frame 1, and the emergency door 2 can be opened to expand the escape doorway and reduce congestion.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
