Description

Technical Field

[0001] The present invention relates to the technical field of fireproof doors, and in particular to an intelligent sliding steel heat-insulating fireproof 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 fireproof door with a publication number of CN 114592782 A, which relates to the field of fireproof equipment, including: a door frame; a fireproof door panel; a handle; a fireproof 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 relatively moved, thereby pushing the push plate to move upward, so that the top of the push plate contacts the top of the door opening, so as to fill the gap between the door opening and the door frame, thereby realizing the 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, so as to rotate the baffle, so that the connecting hole is unblocked, which provides convenience for the subsequent water flow delivery.

[0004] However, although the existing thermal insulation fire doors can effectively block flames when in use, when trapped persons 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 have poor performance, reducing the versatility of the fire door in assisting trapped persons 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 persons, and does not meet people's use needs.

The position distribution of the two groups of rotating rods 704 is symmetrical about the central axis of the threaded sliding rod 703, which is beneficial for the sliding of the threaded sliding rod 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 relatively.

[0027] like Figure 8As shown, the sliding block 705 forms a sliding structure through the rotating rod 704 and the fixed rod 706, and the rescue drawer 707 forms a telescopic structure through the sliding block 705 and the fixed rod 706 and the fire door body 1.

Under the connection of the connecting rod 901, the connecting gear 903 meshing 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 limit rod 905 through the rotation of the second threaded rod 904, so that the protective plate 906 is separated from the filter net, and the rescue drawer 707 and the filter net are used synchronously, further improving the auxiliary rescue effect of the fire door on trapped persons.
