Description

Technical Field

[0001] The utility model relates to the technical field of fire passage doors, in particular to a fire passage door. Background Art

[0002] Fire escape door, also known as emergency evacuation door, safety emergency door, escape door, safety exit door, emergency exit door or emergency passage door, etc., is a facility that must be possessed for building fire safety. It is mainly used as a fast passage for emergency escape and fire rescue. According to regulations, it is necessary to ensure that the door of the fire escape should be kept open at all times.

[0003] The fire escape is an evacuation passage for personnel, which can be divided into indoor and outdoor parts. It also includes the fire truck passage. The evacuation passage for personnel in the building goes from the room through the evacuation passage to the safe exit (directly leading to the outdoors or the evacuation stairwell).

[0004] Since this door is related to the life safety of personnel, its design should be mainly aimed at ensuring that personnel can escape quickly in emergency situations such as fire. If it needs to be locked, it must be ensured that it can be opened quickly in emergency situations such as fire. In addition, the fire escape door must also meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time.

[0005] However, the current fire escape door can only be in a normally closed state or a normally open state when in use, and cannot be set according to actual needs. Most of the time, it is only needed for individuals to pass through, and the existing one is not convenient for use on demand;

[0006] At the same time, when a fire occurs and emergency evacuation is required, the fire passage door is connected to the fire passage. If the flame lamp rushes into the fire passage through the fire passage door, it will affect the escape of the crowd and the safety is poor. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] A fire escape door comprises an upper door frame 10 and two side door frames 11. Two protective doors 20 are arranged between the upper door frame 10 and the two side door frames 11. Fire push rod locks 21 are arranged at the protective doors 20. The upper door frame 10, the side door frames 11, the protective doors 20 and the fire push rod locks 21 are all structures of existing fire escape doors, and the door opening, closing and locking methods thereof can adopt existing methods.

[0039] In the examples of this application, please refer to Figure 1 A small door 30 is rotatably provided at one of the protective doors 20. The small door 30 can use an existing door lock. Normally, the small door 30 can be in an open state to allow pedestrians to pass through, and there is no need to open the entire protective door 20. It is also convenient to close when needed. At the same time, glass windows 40 are inlaid in the small door 30 and the protective door 20 to facilitate users to observe the situation behind the door through the door. The glass used for the glass window 40 is preferably tempered glass.

[0040] In another embodiment, see Figure 1 and 2 The interior of the upper door frame 10 is fixedly connected with a transverse pipe 50 through a fixing buckle 60, and the transverse pipe 50 is connected to an external water source through a water inlet structure 70. The bottom of the transverse pipe 50 is connected with a plurality of water outlet structures 80 extending to the bottom of the upper door frame 10. Specifically, the water outlet structure 80 includes a groove 82 opened at the bottom of the upper door frame 10, and a branch pipe 81 extending to the inside of the groove 82 is fixed at the bottom of the transverse pipe 50. The bottom of the branch pipe 81 is threadedly connected with a nozzle 83. When needed, water is introduced through the water inlet structure 70, and then the water enters the branch pipe 81 through the transverse pipe 50, and finally sprayed out through the nozzle 83. Therefore, when a fire occurs, it can not only play a certain fire extinguishing role, but also isolate the flame and cool and humidify the people passing by, thereby effectively increasing the probability of survival of the people and having higher safety. At the same time, the number of nozzles 83 can be selected as needed. When the nozzle 83 is not needed, the nozzle 83 can be unscrewed and the sealing sleeve 84 can be screwed on at the corresponding position.

[0041] For further information, see Figure 1 , 2 And 3, the water inlet structure 70 includes a water inlet pipe 71 with one end extending to the front of the upper door frame 10 and the other end connected to an external water source. The external water source can be an existing fire water source or a fire pipe, etc. A solenoid valve 72 is provided at the water inlet pipe 71. The solenoid valve 72 can be an existing one and can be connected to an existing fire network in an existing manner and remotely controlled to be opened and closed in an existing manner. The cross pipe 50 is connected to one end of a connecting pipe 74, and the other end of the connecting pipe 74 is connected to the water inlet pipe 71 through a connecting elbow 73. When in use, the solenoid valve 72 is opened to allow the fire water to pass through the water inlet pipe 71, the connecting elbow 73, and the connecting pipe 74 in sequence and then enter the cross pipe 50. In this embodiment, the solenoid valve 72 can be remotely controlled by connecting to the fire network in an existing manner, and can be specifically controlled by existing technology. This application is only an application, so it will not be repeated.

[0042] In another embodiment, see Figure 1 and 2 A sensing structure 90 is provided at the bottom of the upper door frame 10. Specifically, the sensing structure 90 includes a fixed block 91 fixed to the bottom of the upper door frame 10. A contact switch 92 is provided inside the fixed block 91. The contact end of the contact switch 92 abuts against the protective door 20 and is electrically connected to the solenoid valve 72, preferably in series. The contact switch 92 can adopt an existing one, such as a normally closed push button switch. In normal times, the protective door 20 abuts against the contact switch 92, and the contact switch 92 is in a closed state and is not energized. In the event of a fire, the protective door 20 is opened in an existing manner (the protective door 20 that is not opened can also block the flame, so not opening the door does not affect the use), the contact switch 92 is not abutted, and can be opened, and then the solenoid valve 72 can be energized and started normally.
