Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a flat plate mother-and-child slotted fireproof door. Background Art

[0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time.

[0003] It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc.

[0004] It is specially used to isolate fire sources in residential buildings and plays a huge role in firefighting. Once a fire occurs, people can get a chance to escape through fire doors.

[0005] During the use of existing flat fire doors, the door lock of the fire door is the only connecting pressure point between the two door panels. Since the door panels are heavy, they are impacted by airflow and manpower, so the door lock of the fire door is subjected to a large force under the inertia of its own weight, which can easily cause the door lock of the fire door to be damaged and the fire door to shake, resulting in problems in subsequent use.

[0006] For this reason, we propose a flat plate double grooved fire door to solve the existing problems. Utility Model Content

[0007] The utility model aims to solve the problems existing in the background technology and proposes a flat plate mother-and-child slotted fireproof door.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flat-plate mother-and-child slotted fire door, comprising a main door panel, a mother block and a secondary door panel, wherein a mother block is movably provided in the main door panel, the mother block and the secondary door panel are matched with each other, and a smoke alarm is provided in the main door panel.

[0012] Door shaft sleeves are symmetrically mounted on the sides of the main door panel and the auxiliary door panel facing away from each other through bolts;

[0013] A shaft rod is rotatably mounted on the door shaft sleeve.

[0014] Preferably, the

[0015] A sliding cavity is provided in the main door panel, and a partition is fixed to the inner wall of the sliding cavity by bolts;

[0016] A screw is rotatably mounted on the partition, and a motor is provided on the partition, and one end of the screw is connected to the output end of the motor;

[0017] The mother block is slidably inserted in the sliding cavity, and a threaded hole matching the screw rod is provided on the mother block, and the screw rod and the threaded hole are meshed with each other;

[0018] A smoke alarm is installed on the inner wall side of the sliding cavity by bolts, and a pump body is installed on the bottom end of the inner wall of the sliding cavity by bolts;

[0019] An air inlet pipe is installed at the suction end of the pump body, and one end of the air inlet pipe is connected to the lower surface of the main door panel;

[0020] The discharge end of the pump body is located inside the sliding cavity, and an air outlet is provided at the bottom end of the inner wall of the sliding cavity.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] 1. During the use of the flat-plate mother-and-child slotted fire door of the utility model, when the fire door needs to be in a closed state, the two door panels can be closed, and then the screw rod is controlled to rotate to drive the mother block to be embedded in the child slot, so that the two door panels are connected and fixed to each other. Compared with the traditional door lock method, the above structure can greatly increase the contact connection area of ​​the two door panels, and the airflow, manpower and inertial impact on the door panels can be evenly guided and distributed, thereby improving the connection stability between the door panels;

[0023] 2. Furthermore, when the pump is working, it can draw the external ambient air into the door panel. When the smoke content in the air exceeds the standard due to a fire outside, the smoke alarm will promptly detect the signal and send out an alarm to remind personnel at the first time.
