It is a fire-resistant partition with a certain fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. It is specifically used to isolate fire sources in residential buildings and plays a huge role in fire fighting. Once a fire occurs, people can get a chance to escape through the fire door.

[0003] In the existing fire doors today, for example, the technical structure of the application document with application number CN201721601963.2, a fire door panel and a door frame are included, wherein the fire door panel includes a steel side panel 1, a steel side panel 2 and a center splint, wherein the steel side panel 1 and the steel side panel 2 are detachably connected, and the center splint is clamped between the steel side panel 1 and the steel side panel 2, and a plurality of honeycomb-shaped circular holes are provided on both sides of the center splint, and fireproof sponge blocks are provided in the circular holes.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention provides a door frame, a fire door body, a door frame, a first grounding wire, an electronic lock and an automatic electric shock alarm. When a leakage occurs in the distribution room, the automatic electric shock alarm can emit a buzzing alarm to serve as a warning, reminding the staff to repair in time and prevent the staff from accidentally touching the fire door body. At the same time, the electronic lock is opened, and the motor, output shaft, screw rod, nut seat, connecting frame and trapezoidal block cooperate with each other to push the trapezoidal block to move in the direction of the hinge between the door frame and the fire door body, thereby pushing the fire door body open, avoiding the staff from subconsciously touching the charged door handle in a hurry, further protecting the staff and improving the safety performance of the fire door body.

[0020] (2) The present invention realizes that when the trapezoidal block is pushed to open the door, the touch reset switch is pressed to open the power box. At the same time, the fire door body rotates and opens, so that the top rod is separated from the support of the first contact copper sheet. Under the action of the push spring, the first contact copper sheet and the second contact copper sheet contact each other, so that the wire forms a closed loop. In addition, the second grounding wire moves down and contacts the ground under the cooperation of the partially spiral wire, the core block, the armature, the metal limit slide groove, and the reset spring, so that the charge on the fire door body is timely introduced into the ground, further improving the safety performance of the fire door in the distribution room and greatly reducing the probability of accidents. Only when the two prerequisites of the two copper sheets contacting and the power box opening under the control of the touch switch are met, can a loop be formed to move the second grounding wire down. When the fire door body is opened normally, the second grounding wire will not move down. The present invention has certain practical value and market value.

[0021] (3) The present invention improves the thermal insulation performance of the fire door body by providing the perlite door core board, the fire door body, the edge sealing board, the fire sealing strip, the positioning piece and the fire sealing piece. In the event of a fire, the gaps between the door frame, the threshold frame and the fire door body are effectively isolated to prevent further diffusion of smoke. The smoke alarm can also promptly remind the staff to extinguish the fire, thereby improving the safety performance.
