As such, there is a need for further improvements in existing fire rated door structures.

Disclosure of Invention

The utility model aims at providing a fire door structure is prevented to possess protection device can be when taking place the condition of a fire, automatic protection glass layer, and the separation intensity of a fire stretches.

In order to achieve the above purpose, the utility model adopts the following scheme:

the utility model provides a fire door structure that possesses protection device, includes the door body, be provided with a plurality of glass on the door body, it is a plurality of be provided with on the glass and be used for sealing or opening glass's movable fire damper, it is a plurality of be provided with the synchronous connecting rod between the movable fire damper, the synchronous connecting rod with be provided with between the door body and be used for the restriction the hot melt limit structure of connecting rod activity.

Further, the glass is made of heat insulation materials, and the glass is transparent.

Furthermore, the number of the glass is two, and the glass is arranged at intervals up and down.

Further, the movable fireproof baffle comprises a hidden fireproof box arranged above the glass, and a fireproof baffle is movably arranged in the hidden fireproof box.

Further, the synchronous connecting rod comprises a synchronous rod arranged between the two fireproof baffles.

Furthermore, the hot melt limit structure comprises a hot melt limit adhesive which is arranged outside the synchronizing rod and fixedly connected with the door body, a limit plate is arranged on the synchronizing rod, and the lower surface of the limit plate is abutted against the upper surface of the hot melt limit adhesive.

Further, the door body comprises a door frame, a hinged portion is arranged on the door frame, and a stop door is hinged to the hinged portion.

To sum up, compared with the prior art, the utility model discloses its beneficial effect is:

the utility model provides a present prevent that exist not enough in the fire door structure, through the utility model discloses a structure setting possesses following advantage, and the door body plays the purpose that keeps apart the intensity of a fire and spread, is provided with the glass window of being convenient for to observe on the door body simultaneously, when meetting high temperature, and the baffle of glass window top falls down automatically to the outside intensity of a fire of separation glass window plays the purpose of protection glass window, prevents that glass is damaged, and simple structure, convenient to use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the utility model provides a fireproof door structure with a protection device, which comprises a door body 1, wherein a plurality of glasses 2 are arranged on the door body 1, a plurality of movable fireproof baffles 3 for closing or opening the glasses 2 are arranged on the glasses 2, a synchronous connecting rod 4 is arranged between the movable fireproof baffles 3, and a hot melting limit structure 5 for limiting the movement of the connecting rod 4 is arranged between the synchronous connecting rod 4 and the door body 1;

the plurality of glass 2 can facilitate the observation of two sides of the door body 1, and can be observed from one side to the other side;

when a fire disaster occurs, after the fire spreads to the position near the door body 1, due to the temperature influence of the fire, at the moment, the hot melting limit structure 5 automatically melts after reaching the melting point, originally, the hot melting limit structure 5 keeps limiting the movement of the synchronous connecting rod 4, and at the moment, the synchronous connecting rod 4 moves again.

Synchronous connecting rod 4 is because under the effect of gravity, the lapse, and through synchronous connecting rod 4 drives two the 3 downstream of activity fire damper will correspond glass 2 seals the processing, glass 2 has the protection of activity fire damper 3 plays fire-retardant, the effect of separation high temperature.

Glass 2 adopts thermal insulation material to make, glass 2 is transparent setting.
