Description

Technical Field

[0001] The utility model relates to the technical field of rescue passages, in particular to a rescue passage for upper and lower floors. Background Art

[0002] When installing elevators in old communities, there is often a plan for entry from the same floor. Owners can take the elevator from the first floor and go directly to the living room of their home through the newly added corridor. The current elevator acceptance specifications require that when an elevator malfunctions and traps people, rescue workers can reach the hall door of each elevator from the outside to carry out rescue. If no rescue passage is set up, rescue workers can only pass through the owner's home to reach the elevator door. If no one is at the owner's home, it will bring considerable difficulties to the rescue work. Therefore, it is very necessary to design a rescue passage in the elevator corridor.

In this way, the elevator three-corner key must be used to open the skylight 1, which can prevent it from being opened by mistake; the upper end of the cover frame is fixedly connected with the connecting frame 14 by screws, and the split arrangement can be produced separately during production and assembled later, thereby improving production efficiency; the upper cover plate 12 is provided on the connecting frame 14, and one side of the upper cover plate 12 is rotatably connected to one side of the connecting frame 14, and the upper cover plate 12 and the connecting frame 14 are rotatably connected. The limited locking piece 15 is rotatably connected in the middle of the two adjacent sides of one side of the connection, and a connecting plate 141 is fixedly installed on the connecting frame 14 corresponding to the limited locking piece 15. A slideway is provided on the side of the connecting plate 141, and the limited locking piece 15 is stuck in the slideway and slides at one end away from the upper cover plate 12; the slideway includes an upper slideway 142 that satisfies the movement of the end of the limited locking piece 15 during the process of the upper cover plate 12 being flipped up to an upward flip angle of 89°, a supporting path 143 that satisfies the free fall of the end of the limited locking piece 15 when the upper cover plate 12 is released after being flipped up to an upward flip angle of 89°, a smooth path 144 that satisfies the movement of the end of the limited locking piece 15 during the process of pushing the upper cover plate 12 to flip up an angle of 89° when closing the upper cover plate 12, and a lower slideway 145 that satisfies the movement of the end of the limited locking piece 15 during the process of releasing the upper cover plate 12 to the covering state after the upper cover plate 12 is flipped up to an upward flip angle of 89°.

The end of the limit locking member 15 slides in the upper slideway 142 on the connecting plate 141 until the upper cover plate 12 flips to the 89° position and stops flipping at the limited position. Release the upper cover plate 12, and the end of the limit locking member 15 The head falls from the support track 143 and passes through the second elastic piece 147. The upper cover plate 12 is supported at the bottom of the support track 143, and the elevator personnel can pass through the skylight 1. After passing through, by closing the lower cover 13 and locking it with the elevator three-way key, the upper cover plate 12 is flipped up to the 89° position, and the end of the limit locking member 15 slides to the end from the smooth track 144, and the upper cover plate 12 is released. The end of the limit locking member 15 falls into the lower slide track 145, and the upper cover plate 12 continues to flip to the covering state. The end of the limit locking member 15 passes through the first elastic piece 146 from the lower slide track 145 and enters the upper slide track 142. The upper cover plate 12 is covered and locked with the elevator three-way key. When passing through the skylight 1, first open the upper cover plate 12 and then open the lower cover 13, and first close the upper cover plate 12 and then close the lower cover 13.
