Abstract

The utility model discloses to a fire safety door, which comprises a doorframe, a door panel arranged on the doorframe, a gate lock arranged on the door panel and a collision pole arranged on the door panel. Wherein, a contain is formed at an inclined plane of the bolt corresponding to the door panel on the doorframe, a hinged end is formed by bending one end of the collision pole and an opening end is formed by bending the other end, the hinged end is hinged at the side of the internal plate surface of the doorframe, the opening end is contained in the contain of the door panel, and at least one elastic cell is arranged between the collision pole and the door panel. The utility model has the advantage of being easy to open in an emergency.

Description

Fire exit

[technical field]

The utility model relates to the security against fire technical field, refers in particular to a kind of fire exit.

[background technology]

The entertainment place of concentrating such as personnel such as cinema, bars, in case fire dangerous situation or other emergency occur, of paramount importance is to guarantee that the Field Force can rapid evacuation go to place of safety, and key link wherein to be exactly fire exit can be opened rapidly.Adopt of common fire exit is provided with handled door lock more, it is opened needs swing handle and outer push plate of while, when breaking out of fire dangerous situation or other emergency, because the target of the handle on the fire exit is less, and alarmed mood very easily appears in the Field Force, the difficulty of in time opening fire exit and escaping is bigger, in addition, because the intensive fire exit of pouring into of personnel, occur the outrunner easily by the situation of the people of back extruding, this has just further increased the difficulty of timely opening safety door.

[summary of the invention]

The purpose of this utility model is the existing defective of common fire exit, and a kind of fire exit that is easy to open under the state of emergency is provided.

The purpose of this utility model is to realize by following technical solution: a kind of fire exit, include doorframe, be installed on the door-plate in the described doorframe, be installed on the door lock on the described door-plate, and be arranged at collision bar on the described door-plate, wherein, described door-plate is formed with a socket corresponding to the place, inclined-plane of the dead bolt of described door lock, one end of described collision bar has been bent to form a hinged end, the other end has been bent to form an opening end, described hinged end is articulated in the inner plate surface side of described door-plate, described opening end is contained in the socket of described door-plate, is provided with at least one flexible member between described collision bar and the described door-plate.

In the above-mentioned fire exit, described collision bar is arranged at the medium position of described door-plate.

In the above-mentioned fire exit, the end of the opening end of described collision bar is an inclined-plane, and the inclined-plane of described inclined-plane and described dead bolt tilts in the same way.

In the above-mentioned fire exit, described flexible member is a spring.

Than common fire exit, the beneficial effects of the utility model are: pushing collision bar, collision bar are that fulcrum rotates with its hinged end, and the dead bolt of its opening end compressing door lock makes the dead bolt retraction, thereby can push fire exit open.No matter because the target of collision bar is bigger, and can open fire exit by the pushing collision bar, be initiatively to push collision bar, still pushes collision bar because personnel push, and all can open fire exit, greatly reduces the difficulty of fire exit unlatching.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the structural representation that the utility model fire exit is in closed condition.

Fig. 2 is the structural representation that the utility model fire exit is in opening.

[specific embodiment]

With reference to illustrated in figures 1 and 2, fire exit disclosed in the utility model includes doorframe 10, be installed on door-plate 12 in the doorframe 10, be installed on the door lock (not drawing fully among the figure) on the door-plate 12 and be arranged at collision bar 16 on the door-plate 12, wherein, door-plate 12 is formed with a socket 120 corresponding to the place, inclined-plane of the dead bolt 140 of door lock; One end of collision bar 16 has been bent to form a hinged end 160, and the other end has been bent to form an opening end 162, and hinged end 160 is articulated in the inner plate surface side of door-plate 12, and opening end 162 is contained in the socket 120 of door-plate 120; Be provided with a plurality of springs 18 between collision bar 16 and the door-plate 12, to play the effect of collision bar 16 to original position that recover, certainly, it is not limited to the use spring, also can adopt the flexible member of other type.

Pushing collision bar 16, collision bar 16 are that fulcrum rotates with its hinged end 160, and the dead bolt 140 of its opening end 162 compressing door locks makes dead bolt 140 retractions, thereby can push fire exit open.Because the target of collision bar 16 is bigger, and can open fire exit by pushing collision bar 16, no matter be initiatively to push collision bar 16, still owing to personnel's extruding pushes collision bar 16, all can open fire exit, greatly reduce the difficulty that fire exit is opened, guarantee that personnel on the scene can rapid evacuation arrive place of safety.

The end of the opening end 162 of collision bar 16 is an inclined-plane, and the inclined-plane of this inclined-plane and dead bolt 140 tilts in the same way, and it more helps opening end 162 compressing dead bolts 140 and makes its retraction.

Suitable is, collision bar 16 is arranged at the medium position of door-plate 12, and the people that are more convenient for are with hand or health pushing collision bar 16 and open fire exit.

Claims
