Description

Technical Field

[0001] The present invention relates to the technical field of fire doors, and in particular to a fire door which is convenient for escape. Background Art

[0002] In buildings, fire doors are usually installed in emergency passages to prevent fires. Fire doors can effectively block smoke and heat flow, providing people with precious time to escape. Fire doors are usually kept closed. When a fire occurs, one side of the fire door may be burned by the fire, accompanied by a large amount of toxic gases. The surface of the fire door may have a high temperature, and people may be burned by the high temperature when touching the door body, which is not conducive to people opening the fire door and causes inconvenience. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fire door that is convenient for escape and solve the problem that the surface temperature of the fire door rises easily and burns people in a fire.

[0004] Based on the technical problems existing in the background technology, the present invention proposes a fire door that is easy to escape, including a door frame and a fire door rotatably installed on the door frame, water pipes are installed on both sides of the upper door sill of the door frame, the water pipes have a plurality of nozzles with adjustable water spraying directions, the ends of the water pipes are connected to a pump body and installed on the side of the door frame, and a smoke detection device electrically connected to the pump body is installed on the door frame.

[0005] Preferably, water guide grooves extending from top to bottom are provided on the front and back sides of the fire door.

[0006] Preferably, a rebounder is installed above the door frame, and a metal piece connected to the rebounder pull rod is installed on the side of the fire door. The metal piece is provided with an inverted hill-shaped groove, and the end of the rebounder pull rod is located in the groove.

[0007] Preferably, both sides of the fire door are pulled by rebounders.

[0008] Preferably, the fire door is connected to the door frame via a three-fold hinge.

[0009] Preferably, a hook is provided on the side of the unfolded three-fold hinge, and the hinge axis of the three-fold hinge can be fixed in the hook after the three-fold hinge is bent.

[0010] Compared with the prior art, the fire door for facilitating escape proposed by the present invention adopts the above technical solution and achieves the following technical effects:

[0011] The present invention can cool down the surface of the fire door when a fire occurs, making it easier for people to push and pull the fire door and avoid scalding. In the present invention, through the setting of the three-fold hinge, the fire door can be directly pushed to open, reducing the steps and time required for opening the door and improving the efficiency of personnel use.

[0017] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0019] Example

[0020] Please refer to Figure 1-Figure 4The present invention proposes a fire door 2 that is convenient for escape, including a door frame 1 and the fire door 2 rotatably mounted on the door frame 1. Water pipes 3 are installed on both sides of the upper door sill of the door frame 1. The water pipe 3 has a plurality of nozzles 31 with adjustable water spraying directions. The nozzles 31 need to be adjusted to change directions, and the nozzles 31 are sprayed toward the top of the fire door 2. When liquid is connected to the water pipe 3, the nozzles 31 will spray water columns to the upper end of the fire door 2, and the water will flow down along the surface of the fire door 2 to cool the surface of the fire door 2; the end of the water pipe 3 is connected to the pump body 4 and installed on the side of the door frame 1, and a smoke detection device 5 electrically connected to the pump body 4 is installed on the door frame 1. The water pipe 3 is made of metal. Under normal circumstances, the water pipe 3 will not be filled with water. When the smoke detection device 5 detects smoke, it can allow the pump body 4 to operate so that the water pipe 3 is filled with water.

[0021] In a specific embodiment, refer to Figure 1 , Figure 2 The front and back sides of the fire door 2 are both provided with water guide grooves 21 from top to bottom, and water can flow along the water grooves to cool the fire door 2.

[0022] In a specific embodiment, refer to Figure 1 , Figure 3 A rebounder 6 is installed above the door frame 1, and a metal piece 61 connected to the pull rod of the rebounder 6 is installed on the side of the fire door 2. The metal piece 61 is provided with an inverted hill-shaped groove 611. The end of the pull rod of the rebounder 6 is located in the groove 611. When the door body is opened, a column is provided at the end of the pull rod. The column is located in the groove 611 and can pull the fire door 2 so that the fire door 2 can be close to the door frame 1.

[0023] In a specific embodiment, refer to Figure 1 , Figure 3 , Figure 4 Both sides of the fire door 2 are pulled by the rebounder 6, and the fire door 2 is connected to the door frame 1 through a three-fold hinge 7. A hook 71 is provided on the side of the three-fold hinge 7 after it is unfolded. After the three-fold hinge 7 is bent, the hinge shaft 72 of the three-fold hinge 7 can be fixed in the hook 71; when the door body is pushed in one direction, one hinge shaft 72 of the three-fold hinge 7 will rotate and always be located in the hook 71 for limiting to prevent separation, and the other hinge shaft 72 will not rotate, and will separate from the hook 71 and rotate with the fire door 2. When the fire door 2 rotates in the opposite direction, the opposite is true.

[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
