The control assembly of the escape door body 4 is positioned in the upper door frame main body 3, and when the device needs to be overhauled, the upper door frame main body 3 can be detached, so that the operation is simple.
The device not only meets the common advantages of the traditional outward opening type escape door and the traditional embedded escape door, but also has no defects of outward opening type escape door and embedded escape door, and has low manufacturing cost and convenient use.
Example 2
In the present embodiment, the escape door body 4 may be closed by itself to affect escape of people, and the present embodiment is an improvement made on the basis of the embodiment 1, specifically, please refer to fig. 4 and fig. 7, a second fixing block 46 is fixedly mounted at the upper end of the escape door body 4, a sliding rod 47 is rotatably mounted on the second fixing block 46, and the sliding rod 47 is slidably connected with the upper door frame main body 3.
One end of the escape door body 4 rotates relative to the first fixing block 41, and in the rotating process, the other end of the escape door body 4 slides with the upper door frame main body 3 through the sliding rod 47, so that the first fixing block 41 and the escape door body 4 slide until the escape door body 4 is completely parallel to the side door frame main body 2, and the two escape door bodies 4 perform relative movement at the same time, so that the space of an escape passage is enlarged, people can conveniently pass through the escape door, and people can conveniently avoid risks.
The escape door body 4 moves through the first fixing block 41 and the second fixing block 46 at the same time, so that the stress area is increased, and the sliding process is stable.
The bottom wall of the upper door frame main body 3 is provided with a sliding chute 31, the central part of the sliding chute 31 is provided with a limiting rod 32, the sliding chute 31 is connected with a sliding rod 47 in a sliding way, and one end of the chute wall of the sliding chute 31 is fixedly provided with a ratchet bar 33.
Through installation gag lever post 32, make the slide bar 47 of two escape door bodies 4 separately slide, two escape door bodies 4 do not influence each other, convenient to use.
The sliding rod 47 is sleeved with a special-shaped limiting sleeve 48, the special-shaped limiting sleeve 48 slides along the groove wall of the end of the sliding groove 31 far away from the ratchet bar 33, and the sliding rod 47 and the special-shaped limiting sleeve 48 cannot rotate.
One end of the special-shaped limit sleeve 48 is fixedly provided with a limit pawl 49, and the limit pawl 49 is meshed with the ratchet bar 33.
The tilting direction of the ratchet bar 33 is the same as the opening direction of the escape door body 4, and the tilting direction of the limit pawl 49 is the same as the tilting direction of the ratchet bar 33.
When the escape door body 4 is opened, the limiting pawls 49 on the special-shaped limiting sleeves 48 slide along the ratchet bars 33, the limiting pawls 49 have elasticity, in the sliding process of the special-shaped limiting sleeves 48, the limiting pawls 49 sequentially spring into gaps of the ratchet bars 33, however, the ratchet bars 33 have a limiting effect on the limiting pawls 49, and the special-shaped limiting sleeves 48 only can advance and cannot retreat, so that the escape door body 4 cannot be closed after being opened, and escape is facilitated after emergency occurs.
The sliding grooves 31 centered on the limiting rod 32 are arranged in a mirror image manner, and the directions of the internal ratchet bar 33 and the limiting pawl 49 are opposite, so that the two escape door bodies 4 can be opened and limited conveniently.
When the escape door is maintained afterwards, a maintenance worker upwards lifts the special-shaped limiting sleeve 48 and returns the special-shaped limiting sleeve to the initial position of the escape door body 4 when the escape door body is closed, so that secondary use is facilitated, and damage to any mechanism of the escape door body 4 cannot be caused.
