Description

Technical Field

[0001] The present invention relates to the technical field of fire doors, and in particular to an intelligent sliding steel heat-insulating fire door. Background Art

[0002] Fire doors need to meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fire-resistant partitions with a certain degree of 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.

[0003] In the prior art, there is a heat-insulating fire door with the announcement number CN 114592782 A, which relates to the field of fire protection equipment, including: a door frame; a fire door panel; a handle; a fire glass window; a spray mechanism including a connecting hole; and a limiting mechanism. The invention sets a limiting mechanism. When the door frame is placed in the door opening, the worm can be screwed by an external wrench. When the worm rotates, the worm can drive the bidirectional screw to rotate through the worm gear. When the bidirectional screw rotates, the bottom of the cross rotating frame can be moved relative to each other, thereby pushing the push plate to move upward so that the top of the push plate contacts the top of the door opening, thereby filling the gap between the door opening and the door frame, thereby realizing pre-installation of the door frame, thereby saving a lot of time. When the bidirectional screw rotates, the second bevel gear can be driven to rotate by the first bevel gear, thereby rotating the baffle, thereby unblocking the connecting hole and providing convenience for subsequent water flow delivery.

[0004] However, although the existing thermal insulation fire doors can effectively block flames when in use, when trapped people are trapped on one side of the fire door, the rescue towels and miniature fire extinguishers that pop out from the inside of the fire door are not good, which reduces the versatility of the fire door in assisting trapped people in self-rescue. In addition, during daily use, the fire door has a low self-purification effect on the smoke present in the fire, which reduces the cleanliness of the air and the safety of the trapped people, and does not meet people's usage needs. For this reason, we propose an intelligent sliding steel thermal insulation fire door. Summary of the Invention

[0052] like Figure 8As shown, a connecting groove is provided at the connection portion between the outer wall of the connecting plate 5 and the threaded slide rod 703. The threaded slide rod 703 forms a lifting structure between the first threaded rod 702 and the connecting plate 5, which is conducive to the rotation of the first threaded rod 702, driving the threaded slide rod 703 to slide along the outer wall of the connecting plate 5, thereby driving the rotating rod 704 to rotate conveniently.

[0053] like Figure 8 As shown, the rotating rod 704 forms a rotating structure between the threaded slide 703 and the sliding block 705. There are two groups of rotating rods 704. The position distribution of the two groups of rotating rods 704 is symmetrical about the central axis of the threaded slide 703, which is conducive to the sliding of the threaded slide 703 through the connection of the sliding block 705, driving the rotating rod 704 to rotate conveniently, and playing the role of driving the sliding block 705 to slide relative to each other.

[0054] like Figure 8 As shown, the sliding block 705 forms a sliding structure between the rotating rod 704 and the fixed rod 706, and the rescue drawer 707 forms a telescopic structure between the sliding block 705 and the fixed rod 706 and the fire door body 1. There are two groups of sliding blocks 705, and the position distribution of the two groups of sliding blocks 705 is symmetrical about the central axis of the rescue drawer 707. A sealing groove is provided at the connection between the outer wall of the fire door body 1 and the rescue drawer 707, which is conducive to the rotation of the rotating rod 704, driving the sliding block 705 to slide along the outer wall of the fixed rod 706, thereby driving the rescue drawer 707 to pop out relatively inside the fire door for use.

[0055] like Figure 6 As shown, rescue towels and small fire extinguishers are placed inside the rescue drawer 707, and the rescue drawers 707 are symmetrically arranged on both sides of the fire door body 1, which is conducive to placing rescue towels and small fire extinguishers inside the rescue drawer 707, thereby improving the auxiliary rescue effect of the fire door on trapped persons.

[0056] like Figure 9 As shown, the adsorption mechanism 8 includes an activated carbon adsorption net 803, a primary filter net 801 is provided on the top of the fixed plate 6, a high-level filter net 802 is provided on one side of the primary filter net 801, and an activated carbon adsorption net 803 is provided on one side of the high-level filter net 802. This is beneficial to the multi-stage adsorption and filtration of smoke through the setting of the adsorption mechanism 8, thereby improving the cleanliness of the air in the fire.

[0057] like Figures 6-10 As shown, the protection mechanism 9 is provided on one side of the adsorption mechanism 8;

[0058] The protection mechanism 9 includes a protection plate 906, a connecting rod 901 is fixedly connected to the top of the sliding block 705, a connecting rack 902 is fixedly connected to the top of the connecting rod 901, the outer wall of the connecting rack 902 is engaged with a connecting gear 903 that is rotatably connected to the inner wall of the fire door body 1, the rotation center of the connecting gear 903 is fixedly connected to a second threaded rod 904 that is rotatably connected to the outer wall of the fixed plate 6 through a rotating shaft, the outer wall of the second threaded rod 904 is threadedly connected to the protection plate 906 that is slidably connected to the outer wall of the fixed plate 6, and the outer wall of the protection plate 906 is slidably connected to the outer wall of the fixed plate 6 The fixedly connected limiting rod 905, by providing a protective plate 906, is conducive to the relative sliding out of the rescue drawer 707 in the event of a fire. Under the connection of the connecting rod 901, the connecting gear 903 engaged with the connecting rack 902 is driven to rotate. The rotation of the connecting gear 903 drives the protective plate 906 to slide along the outer wall of the limiting rod 905 through the rotation of the second threaded rod 904, so that the protective plate 906 is separated from the filter screen, playing the role of synchronous use of the rescue drawer 707 and the filter screen, further improving the auxiliary rescue effect of the fire door on trapped persons.

[0059] like Figure 9 As shown, the connecting gear 903 forms a rotating structure with the fire door body 1 through the connecting rod 901 and the connecting rack 902. The sliding block 705 and the connecting rod 901 are arranged in a one-to-one correspondence, which is conducive to the connection of the connecting rod 901. Through the connection of the connecting rack 902, the connecting gear 903 is driven to rotate along the inner wall of the fire door body 1, thereby driving the second threaded rod 904 to rotate synchronously.

[0060] like Figure 10 As shown, the second threaded rod 904 forms a rotating structure with the connecting rack 902 and the connecting gear 903 and the fixed plate 6, and the rotation center of the second threaded rod 904 and the rotation center of the connecting gear 903 are arranged to coincide with each other, and the protective plate 906 forms a sliding structure with the second threaded rod 904 and the limiting rod 905. The outer wall profile of the protective plate 906 is L-shaped, which is conducive to the sliding of the connecting rack 902. Through the connection with the connecting gear 903, the second threaded rod 904 is driven to slide along the outer wall of the fixed plate 6, which plays a role in driving the convenient telescopic movement of the protective plate 906, and plays the role of using the rescue drawer 707 and the filter screen synchronously, further improving the auxiliary rescue effect of the fire door on trapped persons.

[0061] Working principle:

[0062] like Figure 1-10As shown, when the heat-insulating fire door is used, first, in order to improve the multifunctionality of the fire door in preventing fire and assisting rescue at the same time when a fire occurs, the micro servo motor 701 is turned on and the first threaded rod 702 is rotated to drive the threaded sliding rod 703 to slide along the outer wall of the connecting plate 5. The rotation of the rotating rod 704 drives the sliding block 705 to slide along the outer wall of the fixed rod 706, and drives the two sets of rescue drawers 707 to slide out from the outer wall of the fire door relative to each other, so that people trapped in the fire can promptly take the rescue towels and fire extinguishers in the rescue drawers 707 for self-rescue.

[0063] Next, during daily fire prevention in a fire, in order to improve the fire door's ability to absorb and filter smoke and reduce the difficulty in breathing caused by smoke passing through the door body, a multi-stage filter is installed on the outer wall of the fixed plate 6 to perform multi-stage absorption and filtration of smoke, thereby improving the cleanliness of the air in a fire.

[0064] Finally, in the event of a fire, when the rescue drawer 707 slides out relatively, the connecting gear 903 meshing with the connecting rack 902 is driven to rotate under the connection of the connecting rod 901. The rotation of the connecting gear 903 drives the protective plate 906 to slide along the outer wall of the limiting rod 905 through the rotation of the second threaded rod 904, so that the protective plate 906 is separated from the filter net, playing the role of synchronous use of the rescue drawer 707 and the filter net, further improving the auxiliary rescue effect of the fire door on trapped persons.

[0065] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above.
