Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a steel-wood fire door. Background Technology

[0002] Steel-wood fire doors typically use fire-retardant wood or steel materials for the door frame and door panel, and then add non-toxic fire-resistant and heat-insulating materials inside the door panel. They have a certain fire resistance and can block the spread of fire to some extent.

[0003] Chinese utility model patent with authorization announcement number CN106593248A discloses a high flame-retardant steel-wood fire door, including a door frame, a door leaf, fireproof hinges, a fireproof expansion sealing strip, and a locking pin device. The fireproof expansion sealing strip is embedded in the contact surface between the door frame and the side of the door leaf. The locking pin device is set on the upper edge of the door frame and between the door leaf, and multiple locking pin devices are arranged at intervals.

[0004] The existing technical solutions mentioned above have the following drawbacks: Since the fire-resistant expansion sealing strip is installed on the edge of the door leaf, if a fire occurs, the fire-resistant expansion sealing strip will expand due to heat and seal the gap between the door leaf and the door frame. However, this will also increase the friction between the door leaf and the door frame, making it difficult to open the fire door when personnel need to be evacuated. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel-wood fireproof door that addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a steel-wood fireproof door, including a door frame, a door panel inside the door frame, a cavity inside the door frame, and sealing mechanisms on both the left and right sides of the inner wall of the door frame. The sealing mechanism includes a sealing plate, a spring, a triangular block, and a triangular block. The sealing plate is slidably connected to the left and right sides of the inner wall of the door frame. The spring is located inside the cavity. The triangular block is fixedly connected to one side of the sealing plate and located inside the cavity. The triangular block is located on one side of the triangular block.

[0007] Preferably, a cover plate is provided on the front of the door frame, a lever is fixedly connected to the front of the second triangular block, and the two ends of the first spring are fixedly connected to the inner wall of the cavity and the outer wall of the sealing plate, respectively. The first spring is provided to drive the sealing plate to reset, and an elastic sealing gasket is provided on the side of the sealing plate facing the door panel.

[0008] Preferably, a limiting rod is fixedly connected to the bottom of the inner wall of the cavity, and the limiting rod passes through the lever and is slidably connected to the lever. By setting the limiting rod, the second triangular block can move up and down horizontally.

[0009] Preferably, the outer wall of the limiting rod is fitted with a second spring, and the two ends of the second spring are fixedly connected to the bottom of the lever and the bottom of the inner wall of the cavity, respectively. By setting the second spring, the triangular block can be reset.

[0010] Preferably, a connecting plate is fixedly connected to the inner wall of the cavity, a connecting rod is rotatably connected to the top of the paddle, and a limiting piece is fixedly connected to the top of the connecting rod, with the limiting piece embedded inside the connecting plate.

[0011] Preferably, an inner panel is fixedly connected to the front of the door panel, and the inner panel is embedded in the front of the door frame. By setting the inner panel, the top and bottom of the door panel and the door frame can be sealed.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This steel-wood fire door, by installing the door frame in a suitable position, allows for opening the cover plate and pushing the lever upwards in the event of a fire. The lever causes triangular block two to press against the inclined surface of triangular block one, causing the sealing plate to press against the outer wall of the door panel, thereby sealing the door panel and preventing smoke from passing through. When it is necessary to open the door panel, triangular block two is no longer pressing against triangular block one, so that the sealing plate is no longer in contact with the door panel, making it easy to open the door panel.

[0014] 2. This steel-wood fire door allows the limiting plate to pass through the connecting plate when the lever is turned. At this time, the sealing plate abuts against the side of the door panel. Rotating the limiting plate to make it cross-shaped with the connecting plate keeps the triangular block two in a compressed state. Rotating the limiting plate to make it parallel to the hole on the connecting plate allows the lever to automatically reset, thereby automatically resetting the sealing plate, providing convenience for sealing operations.

[0023] Please see Figure 1-3One embodiment of this utility model is as follows: a steel-wood fire door includes a door frame 1, a door panel 2 inside the door frame 1, a cavity 4 inside the door frame 1, and sealing mechanisms 5 on both the left and right sides of the inner wall of the door frame 1. The sealing mechanism 5 includes a sealing plate 51, a spring 52, a triangular block 53, and a triangular block 54. The sealing plate 51 is slidably connected to the left and right sides of the inner wall of the door frame 1. The spring 52 is located inside the cavity 4. The triangular block 53 is fixedly connected to one side of the sealing plate 51 and located inside the cavity 4. The triangular block 54 is located to one side of the triangular block 53. A cover plate is provided on the front of the door frame 1. A lever 55 is fixedly connected to the front of the triangular block 54. The two ends of the spring 52 are respectively fixed to the inner wall of the cavity 4 and the outer wall of the sealing plate 51. The connection is achieved by setting spring 52 to reset the sealing plate 51. The sealing plate 51 has an elastic sealing gasket on the side facing the door panel 2. The bottom of the inner wall of the cavity 4 is fixedly connected to a limit rod 56, which slides through the lever 55. The limit rod 56 allows the triangular block 54 to move horizontally up and down. The outer wall of the limit rod 56 is fitted with a spring 57, and the two ends of the spring 57 are fixedly connected to the bottom of the lever 55 and the bottom of the inner wall of the cavity 4, respectively. The spring 57 can reset the triangular block 54. The front of the door panel 2 is fixedly connected to an inner plate 3, which is embedded in the front of the door frame 1. The inner plate 3 can seal the top and bottom of the closing part of the door panel 2 and the door frame 1.

[0024] Working principle: By installing the door frame 1 in a suitable position, in the event of a fire, the cover is opened and the lever 55 is pushed upward. The lever 55 drives the second triangular block 54 to press the inclined surface of the first triangular block 53, so that the sealing plate 51 presses against the outer wall of the door panel 2, thereby pressing against the door panel 2 to achieve the purpose of sealing and preventing smoke from passing through. When it is necessary to open the door panel 2, the second triangular block 54 stops pressing against the first triangular block 53, so that the sealing plate 51 no longer abuts against the door panel 2, thus making it easy to open the door panel 2.

[0025] Please see Figure 1-3 Based on the above embodiments, in another embodiment of the present invention, a connecting plate 7 is fixedly connected to the inner wall of the cavity 4, a connecting rod 6 is rotatably connected to the top of the paddle 55, and a limiting piece 8 is fixedly connected to the top of the connecting rod 6, and the limiting piece 8 is embedded inside the connecting plate 7.

[0026] Working principle: When the lever 55 is turned, the limiting piece 8 passes through the connecting plate 7. At this time, the sealing plate 51 abuts against the side of the door panel 2. Then, the limiting piece 8 is rotated so that it forms a cross shape with the connecting plate 7, so that the triangular block 2 54 is kept in a compressed state. Rotating the limiting piece 8 so that it is parallel to the hole on the connecting plate 7 will cause the lever 55 to automatically reset, thereby causing the sealing plate 51 to automatically reset, providing convenience for sealing operation.
