Problems solved by technology

Existing fire doors usually only have the function of preventing the spread of fire and preventing the spread of smoke, and do not have the function of emergency lighting. As a result, people may not be able to see the fire doors clearly when there is a fire and power failure or when the normal lighting power supply fails. The specific location of the fire and the surrounding fire conditions, thus missing the best time to escape, causing irreparable damage

Embodiment 1

[0020] Such as Figure 5 As shown, the emergency lighting device 20 is directly connected to an external AC power source, and includes a box body, a light emitting device 21 disposed on the front side of the box body 24 , a power-off start switch 22 and a battery 23 disposed inside the box body 24 . The light emitting device 21 is a plurality of LED lamps evenly arranged on the front surface of the box body. In this embodiment, the box body 24 is a rectangular flat box body 24 made of aluminum-silicon alloy die-cast and sprayed on the surface. Such as Figure 5 As shown, the power-off start switch 22 is connected to the light-emitting device 21 and the battery 23, and is connected to the battery 23 and the light-emitting device 21 in case of emergency power-off, and the battery 23 supplies power to make the light-emitting device 21 emit light. Such as Figure 5 As shown, the power-off start switch 22 is a relay, which includes a normally open relay 221 and a normally closed...

Embodiment 2

[0023] Such as Figure 3A , Figure 3B , Figure 4A , Figure 4B As shown, the basic structure of the fire door with escape lighting function is the same as that of Embodiment 1, the difference is that the emergency lighting device 20 is mounted and fixed on the upper frame 11 of the door frame by a known wall hanging method such as screw fixing. On the surface of the front and rear sides, it is easy to install and replace.

Abstract

A fireproof door with an escape lighting function comprises a door frame and a door movably connected with the door frame. The fireproof door is characterized in that emergency lighting devices connected with an external alternating current power supply directly are arranged on the door frame, and each of the emergency lighting devices comprises a box body, a luminescent device, an outage start switch and a storage battery. The luminescent devices are arranged on the front sides of the box bodies, and the outage start switches and the storage batteries are arranged in the box bodies. The outage start switches are connected with the luminescent devices and the storage batteries and communicated with the luminescent devices and the storage batteries under the situation of emergency outage, and the storage batteries supply power for the luminescent devices to enable the luminescent devices to glow. The emergency lighting devices are arranged on front and rear sides of the top border edge of the door frame. By means of the fireproof door, emergency lighting can be provided under the condition of outage, so that persons can be helped to escape in order during the fire. The fireproof door has the advantages of being simple in structure, easy to implement and the like.

Description

【Technical field】 [0001] The invention relates to a fire door for building fire protection, in particular to a fire door with escape lighting function which can provide emergency lighting to help evacuated personnel escape in an orderly manner. 【Background technique】 [0002] A fire door is a door made of fire-resistant and flame-retardant materials with high temperature resistance, airtightness and heat insulation. In the event of a fire, completely isolate the fire point from the escape route to block the spread of the fire and prevent the spread of smoke. With the increasing maturity of fire protection technology, fire doors, as a commonly used fire partition, are widely used in buildings and public places. Existing fire doors usually only have the function of preventing the spread of fire and preventing the spread of smoke, and do not have the function of emergency lighting. As a result, people may not be able to see the fire doors clearly when there is a fire and power...
