Description

Technical Field

[0001] The utility model relates to a steel heat-insulating fireproof door, belonging to the field of fireproof doors. Background Art

[0002] Fire doors are doors with fire resistance. They block the air flow between two spaces in case of fire, prevent the spread of thick smoke, toxic gases and hot air, and resist fire for a certain period of time, delaying or controlling the spread of fire. Therefore, fire doors play a vital role in the event of fire. At present, fire doors are widely used in many fields such as residential houses, ships, construction, chemical industry, mechanical engineering, etc. Commonly used fire doors are metal doors, which can effectively prevent the spread of fire by taking advantage of the high melting point of metal.

[0003] In the prior art, 80% of the victims in a fire die from suffocation due to inhaling a large amount of smoke. However, the fire door needs a signal from the fire control center when in use, so that the fire door can be slowly closed by the motor. When a fire occurs, a large amount of smoke will be generated before combustion, and it is difficult to block the smoke in time, causing the indoor smoke to spread rapidly, thus causing personal accidents. Therefore, it is necessary to design a steel insulated fire door that can block smoke autonomously. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a steel insulated fireproof door to solve the problems raised in the above-mentioned background technology. The present invention performs self-barrier to prevent the spread of smoke and dust.

[0007] Furthermore, the installation frame is located at the back of the door panel, and the installation frame is wrapped around the outside of the self-breaking component, and the rolling door is located between the installation frame and the door panel.

[0008] Furthermore, the rolling shutter door is rolled up and arranged above the fusible plate, and the sealing frame is located at the edge of the rolling shutter door, and the sealing frame is made of silicone material.

[0009] Furthermore, the interior of the self-breaking component includes a support block, a fusible link, a retractable rod, a sleeve, a connecting shaft and a driving shaft. The inner wall of the mounting frame is fixedly connected to the support block, the outer wall of the support block is installed with a fusible link, the other end of the fusible link is fixedly connected to the retractable rod, the top of the support block is fixedly connected to the sleeve, the interior of the mounting frame is installed with a connecting shaft, and the outer wall of the connecting shaft is installed with a driving shaft.

[0013] The beneficial effects of the utility model: the utility model can drive the installation frame to move through the sliding component, so that the installation frame can be aligned with the door frame outside the door panel, which is convenient for blocking smoke and preventing smoke from spreading in the event of a fire. At the same time, self-breaking components are used on both sides of the sealing plate, so that when the fire temperature reaches a certain level, the fusible piece can melt automatically, so that the retractable rod can be retracted into the sleeve, thereby driving the internal connecting shaft and the driving shaft to move, so that the sealing plates are closed to each other, and at the same time, the sealing strip seals the gap position of the sealing plate, so that the barrier effect is better and the smoke barrier effect is more efficient.

[0014] Through the setting of the rolling shutter door, when a fire occurs, the fusible plate can be heated and melted, and the rolling shutter door can be instantly closed by gravity without the need for a signal from the central control. When a fire occurs, the fire door position can be instantly closed, which can quickly cut off the fire path and effectively prevent the fire. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the self-breaking components 11 are used on both sides of the sealing plate 12, so that when the fire temperature reaches a certain level, the fusible piece 1102 can melt automatically, so that the retractable rod 1103 is retracted into the sleeve 1104, thereby driving the internal connecting shaft 1105 and the driving shaft 1106 to move, so that the sealing plates 12 are closed to each other, and at the same time, the sealing strip 13 seals the gap position of the sealing plate 12, so that the blocking effect is better and the smoke and dust blocking effect is more efficient.

[0025] See also Figures 3 to 6 The utility model provides a technical solution: the interior of the sliding component 2 includes a driving motor 201, a driving threaded rod 202 and an adjusting threaded barrel 203, the driving motor 201 is installed inside the door frame 1, the output shaft of the driving motor 201 is fixedly connected to the driving threaded rod 202 through a coupling, and the external thread of the driving threaded rod 202 is connected to the adjusting threaded barrel 203.

[0026] The above structure drives the threaded rod 202 to rotate through the driving motor 201, thereby driving the installation frame 3 to move.

[0027] Preferably, the mounting frame 3 is located at the back of the door panel 8 , and the mounting frame 3 is wrapped around the outside of the self-breaking component 11 , and the rolling door 4 is located between the mounting frame 3 and the door panel 8 .
