[0002] Fireproof windows have been widely used in the construction industry. Their main function is to prevent the spread of fire after a fire occurs.

[0003] When existing steel non-insulated fire-resistant windows are used, they are usually opened and closed by fireproof door closers. Usually, fireproof door closers are connected to steel non-insulated fire-resistant windows by bolts. However, for safety reasons, they usually need to be disassembled and maintained regularly, which can easily cause wear on the bolts and make them unstable. For this reason, we propose steel non-insulated fire-resistant windows. Utility Model Content

[0012] It is convenient to pull the connecting pull block to drive the movable limit rod and the force-bearing ring to move, compress the first spring, so that one end of the movable limit rod can be pulled out from the inner side of the limit hole, thereby quickly disassembling the movable mounting plate and the limit frame, and the operation is convenient.

[0014] It is convenient to move the toggle block so that the connection limit block can push the movable installation block and shrink toward the inside of the fixed sleeve block, so that the movable installation block compresses the second spring, thereby enabling the connection limit block and the fixed card rod to be separated from each other, and then the fixed connection arm can be quickly separated from the fixed card rod, which is easy to operate.

[0015] In a further technical solution, one end of the movable limiting rod is in contact with the inner side of the limiting hole, and the inner side of the arc groove is in contact with the inner side of the fixed slot.
