Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, in particular to an overlapping emergency evacuation door. Background Art

[0002] Sliding doors are mainly controlled by sliding door operators (sometimes also called door machines) to achieve automatic opening and closing of doors. In product and market classification, some call them sliding doors and some call them translation doors, but in terms of functional structure and application, the two are essentially the same. The structure of a sliding door is relatively simple, mainly consisting of a door frame assembly, a door body, and a push-pull device located between the door body and the door frame assembly. The door frame assembly usually includes an upper slide rail and a lower slide rail that are parallel to each other, and the door body is slidably arranged between the upper slide rail and the lower slide rail.

[0003] The track at the bottom of the sliding door is mostly integrated with the door frame. The lower track is on the ground and has more contact with pedestrians. After long-term use, the lower track will rust and age. If it is not replaced in time, it may cause the door body to slide poorly or get stuck, thereby increasing the risk of personnel evacuation in an emergency. In addition, the door body needs to be completely disassembled before replacing the track. This process is not only time-consuming, but also requires professional skills and tools, which increases the complexity of the operation. The long disassembly and installation process will delay the normal use time of the sliding door. For places that require frequent passage, it may cause inconvenience and congestion. For this reason, an overlapping emergency evacuation door is proposed. Utility Model Content

[0034] In the embodiment of the present application, the number of evacuation door bodies 12 is six, and the six evacuation door bodies 12 are all slidably connected to the inner cavity of the outer door frame 11, and are symmetrically distributed on both sides of the inner cavity of the outer door frame 11, which increases the passage width of the evacuation door bodies 12 and improves the emergency evacuation efficiency. The lower guide rail 13 is located at the bottom of the inner side of the outer door frame 11, and the connecting member 2 includes four mounting plates 21 fixedly connected to the front and rear sides of the lower guide rail 13. A through hole 22 is provided on the top of the mounting plate 21, and the mounting seat 31 is fixedly connected to the four mounting seats 31 on the front and rear sides of the bottom of the outer door frame 11 respectively. The positions of the four mounting seats 31 are adapted to the positions of the four mounting plates 21, and the inner cavity of the mounting seat 31 is movably connected to the mounting plate 21. The mounting seat 31 and the mounting plate 21 are used in combination, which is convenient for the preliminary positioning of the lower guide rail 13 when it is installed. A groove 32 is provided on the inner side of the mounting seat 31, and the side wall of the groove 32 is aligned with the mounting plate 21. The movable connection is convenient for providing support and fixing points for the mounting seat 31. The column 33 is fixedly connected to the bottom of the inner cavity of the mounting seat 31, and the fixing block 34 is fixedly connected to the top of the column 33. The fixing block 34 is in a U-shape, and the U-shape is designed to accommodate the moving block 35. The moving block 35 is movably connected to the inner cavity of the fixing block 34. When the moving block 35 is pushed into the inner cavity of the fixing block 34, the mounting plate 21 is unlocked, so that the lower guide rail 13 can move upward and detach from the mounting seat 31, which is convenient for disassembly. Both sides of the moving block 35 are fixedly connected with protrusions 36, and both sides of the fixing block 34 are provided with limiting holes 37 for the movement of the protrusions 36.
