Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a normally open Class A fireproof door leaf storage frame. Background Art

[0002] Fire doors are an important part of fire protection equipment and are divided into Class A, Class B, Class C, etc. They are an important part of the fire protection system. Therefore, the quality and use of fire doors are the key to the success of fire protection. Taking Class A fire doors as an example, Class A fire doors are the highest level of fire doors. Their fire resistance time is not less than 1.5 hours. They can withstand the most severe fire environment and effectively isolate the fire source to limit the spread of fire. They are generally suitable for important places with dense personnel, such as operating rooms, vaults, etc., and to facilitate passage and prevent damage caused by frequent closure of fire doors, fire doors that are frequently passed by people should adopt normally open fire doors. The current common normally open Class A fire door opening method is mainly to open it manually and then use the limit latch to insert the ground to keep the fire door in a normally open state. Once a fire occurs, if the personnel fail to unlock the fire door in time, it is easy for the fire to spread to other spaces, causing irreparable losses. Utility Model Content

[0018] The following is combined with Figure 1-2 , the technical solution of the utility model is further explained:

[0019] like Figure 1-Figure 2As shown, the utility model discloses a normally open Class A fire door leaf storage frame, comprising a main frame 1, wherein a Class A fire door 2 is movably arranged in the main frame 1. That is, two Class A fire doors 2 are movably opened in the main frame 1, and one end of the Class A fire door 2 is movably connected to the main frame 1 through a door frame hinge.

[0020] Sub-frames 3 are respectively provided on both sides of the main frame 1 and extend outward in a horizontal direction perpendicular to the main frame 1. In other words, sub-frames 3 are respectively vertically installed on both sides of the main frame 1, and the fire door is adsorbed and limited by the sub-frames 3, and the fire door is kept in a normally open and horizontally opened state in cooperation with the opening structure on the main frame 1.

[0021] It should be noted that in this embodiment, the main frame 1 and the sub-frame 3 are an integrally formed structure, which can ensure the stability of the overall structure.

[0022] Specifically, Figure 1 As shown, an opening mechanism is provided between the main frame 1 and the Class A fire door 2. That is, the opening mechanism provided on the main frame 1 can push the Class A fire door 2 to open or pull the Class A fire door 2 to close.

[0023] In some embodiments, the opening mechanism includes a power member, on which a link adjustment member is movably provided, and the link adjustment member is connected to a connection block provided on the Class A fire door 2. That is to say, the power member drives the link adjustment member to move, for example, when the power member moves outward, it can drive the linkage adjustment member to push the Class A fire door outward, and the Class A fire door is then opened; when the power member moves inward, it can drive the linkage adjustment member to pull the Class A fire door inward, and the Class A fire door is then closed.

[0024] The power member includes a sliding linear module 4, and a slider in the sliding linear module 4 is movably connected to the linkage adjustment member. That is to say, in this embodiment, the power member uses a sliding linear module 4, and the slider in the sliding linear module 4 has high stability and directional movement when it moves, and because of the threaded connection between the slider and the internal screw rod, when the slider stops, the slider and the screw rod can maintain a good self-locking state to prevent the slider from sliding off the screw rod, thereby ensuring the reliability of the linkage adjustment member when it moves.

[0025] It should be noted that the power part can also be replaced by a telescopic power part such as a cylinder.

[0026] In some embodiments, Figure 1As shown, the link adjustment member includes a first movable rod and a second movable rod, one end of the first movable rod is movably connected to the slider in the sliding linear module, the other end of the first movable rod is movably connected to one end of the second movable rod, and the other end of the second movable rod is connected to the connecting block. That is to say, when the power member moves, the first movable rod moves synchronously with the power member, the first movable rod drives the second movable rod to move, and the second movable rod drives the connecting block and the fire door to move, thereby completing the opening or closing action of the fire door.

[0027] like Figure 2 As shown, the sub-frame 3 is provided with a limiting cavity for accommodating the opening mechanism, and the sub-frame 3 is provided with a limiting mechanism corresponding to the Class A fire door 2. In other words, a limiting mechanism is also provided on the sub-frame 3, and the Class A fire door 3 is attracted to the limiting mechanism on the sub-frame 4 after being opened horizontally under the pushing action of the opening mechanism, so that the Class A fire door is stably maintained in a 90° opening state under the cooperation of the opening mechanism and the limiting mechanism.

[0028] In some embodiments, Figure 2 As shown, the limiting mechanism includes a first limiting member, and the Class A fire door 2 is provided with a second limiting member corresponding to the first limiting member, and the first limiting member cooperates with the second limiting member to adsorb and fix the Class A fire door 2 on the sub-frame 3. In other words, the first limiting member and the second limiting member are respectively provided on the sub-frame 3 and the fire door 2, and when the fire door is opened and approaches the sub-frame, the first limiting member and the second limiting member are attracted to adsorb the fire door on the sub-frame, and the sub-frame remains in a horizontally opened state.

[0029] In some embodiments, the first limiting member includes a first limiting magnetic block 6, which is connected to the sub-frame 3 through a spring damper; the second limiting member includes a second limiting magnetic block 5, which is attracted to the first limiting magnetic block 6 and the second limiting magnetic block 5. In other words, the sub-frame is fixed by the first limiting magnetic block and the second limiting magnetic block, and when the fire door is opened and contacts the sub-frame, the spring damper is used for buffering to avoid collision between the fire door and the sub-frame.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
