[0002] Firefighting is to eliminate hidden dangers and prevent disasters. It is a general term for preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study. Of course, the meaning of firefighting in the early stage of people's understanding is: extinguishing fire, which mainly includes the rescue of personnel at the fire scene, the rescue of important facilities and equipment, cultural relics, the safety protection and rescue of important property, extinguishing fire, etc. The purpose is to reduce the degree of damage caused by fire, reduce casualties and property losses.
[0003] A fire door is a door that meets the requirements of fire resistance, stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.

DETAILED DESCRIPTION
[0019] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: a fire door for a fire passage with an anti-stuckness for an inpatient building, comprising a door closer 1, the door closer 1 is installed on the upper part of a door frame 3, the door closer 1 is connected to a first evacuation door 2 through the door frame 3, a hinge 4 is installed between the first evacuation door 2 and the door frame 3, a handle 6 is installed on the surface of the first evacuation door 2, an emergency push plate 7 is movably installed at the bottom of the first evacuation door 2, a rotating buckle 16 is installed on the upper part of the emergency push plate 7, a second evacuation door 5 is installed on one side of the first evacuation door 2, a baffle 13 is installed between the second evacuation door 5 and the door frame 3, a movable column 12 runs through the baffle 13 and the second evacuation door 5, a fixing plate 15 is installed at the bottom of the baffle 13, a spring 14 is installed on the top of the fixing plate 15, a pull rod 8 is installed at the bottom of the fixing plate 15, the pull rod 8 is installed on the surface of a pressure rod 10, supports 9 are installed at both ends of the pressure rod 10, and the rotating buckle 16 is installed inside the protective cover 11.
[0021] In this embodiment, Figure 3As shown, the pressure rod 10 forms a sliding structure with the pull rod 8 and the baffle 13; when the pressure rod 10 is pressed downward through the support 9, the pull rod 8 is driven to move downward, and the baffle 13 is pulled downward as a whole. The operator can use the whole body strength to apply to the pressure rod 10 to complete the opening of the second evacuation door 5, and the operation is simple.
[0022] In this embodiment, Figure 4 As shown, the movable column 12 is movably installed in the internal slide groove of the second evacuation door 5; the same baffles 13 are installed at both ends of the movable column 12, and the movable column 12 can link the baffle 13 to move up and down in the slide groove of the second evacuation door 5. The operation is simple and fast, the response is flexible, and it is suitable for use in emergency situations.
[0023] In this embodiment, Figure 1 As shown, a rotating structure is formed between the emergency push plate 7 and the first evacuation door 2, and the emergency push plate 7 is fixed to the first evacuation door 2 by a rotating buckle 16; the emergency push plate 7 is installed at the bottom of the first evacuation door 2, can be flipped open, and locked to the first evacuation door 2 by the rotating buckle 16, and a protective cover 11 is provided on the outside of the rotating buckle 16 to prevent accidental operation. The design avoids the evacuation door being unable to open due to the door closer 1 being stuck, and the operation is suitable for all kinds of people.
[0024] In this embodiment, Figure 1 As shown, the baffles 13 are installed symmetrically about the central axis of the second evacuation door 5, and the baffles 13 move up and down synchronously on both sides of the second evacuation door 5 through the movable columns 12; the baffles 13 are installed on both sides of the outer surface of the second evacuation door 5 and move up and down synchronously to ensure that the second evacuation door 5 is in a normally closed state when not in use.
[0025] In this embodiment, Figure 3 As shown, the installation height of the baffle 13 is higher than the top of the second evacuation door 5, and the movable range of the baffle 13 is limited by the contraction of the spring 14, and the lowest movable position of the baffle 13 is flush with the second evacuation door 5; in the normally closed state, the baffle 13 fixes the door frame 3 and the second evacuation door 5 inside and outside, so the installation height of the baffle 13 must be higher than the top of the second evacuation door 5. When the baffle 13 is pressed down by the tension rod 8, the spring 14 is also pressed down by force, so that the baffle 13 moves down and is flush with the second evacuation door 5. Then, the second evacuation door 5 is not constrained from the door frame 3. At this time, it can be rotated open by the hinge 4, which is conducive to the opening and identification of the operator, and is also convenient for future maintenance.
[0026] The use method and advantages of the utility model: The anti-stuck fire door for fire passages in hospital buildings has the following working process when in use:
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a fire door device for fire escape passages in hospital buildings that prevents jamming has two opening modes in emergency situations. First, the first evacuation door 2 can be opened by the handle 6 under normal circumstances, and the door closer 1 can also be operated normally if there is no problem. In an emergency, some patients or younger patients can operate the rotating buckle 16 to open the emergency push plate 7 for escape if they have less strength. The rotating buckle 16 has a protective cover 11 to protect it, and it will not cause accidental contact under normal circumstances. At this time, there is no need to worry about the evacuation door being stuck or the door closer 1 being rusted. The operation is fast, and there is no need for the evacuees to open the door in advance. The patient can open it by himself. In addition, the second evacuation door 5 of the fire door that prevents jamming is opened. The opening method is to open the evacuation door by pulling down the pull rod 8. When the pressure rod 10 is pulled down, the baffle 13 is driven to move downward, and the spring 14 is compressed so that the baffle 13 is flush with the top of the second evacuation door 5, and the second evacuation door 5 can be opened. In an emergency, the patients in the inpatient building can use their whole body strength to press down the pressure rod 10 to open the evacuation door. The baffles 13 on the inner and outer sides of the second evacuation door 5 move at the same time. When the pressure rod 10 is pressed down, the spring 14 on the fixed plate 15 will be locked through the support 9. Unless the pressure rod 10 is reset, the spring 14 will be under pressure all the time. At this time, the second evacuation door 5 is in a normally open state, which is convenient for personnel evacuation. When it is not necessary, the baffle 13 constrains the door frame 3 and the second evacuation door 5, and the second evacuation door 5 is in a normally closed state.
[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
