Description

Locking system for fireproof window
Technical Field
The present invention relates to a locking system for fire windows.
Background
The state requires that each opening fan is provided with at least one slope spring lock tongue which is usually extended outwards and a corresponding lock catch plate so as to close the window fan by the opening and closing device of the building fire-fighting fire-proof window when a fire disaster occurs, and the window fan is impacted by the window fan to lock the fire-proof window by the lock catch plate and the lock tongue, thereby preventing the fire from spreading and waiting for the fire-proof standard of rescue. Meanwhile, the state requires multi-point locking when the window sashes are closed for the building external window, so that building standards such as airtight, watertight, sound insulation, wind pressure resistance, energy conservation and the like of the window are completed. For the fire-fighting fire-proof window of the building, the two national standards are required to be met at the same time, so that the contradiction that the opening fan is closed or the opening switch is not opened occurs when the spring lock tongue with a slope and the multi-point transmission lock with transmission are used at the same time. At present, two methods for solving the contradiction exist, namely, a plurality of special-shaped spring plates, gears, special-shaped steel plates and other complex structures are used for converting the contradiction into common use, but the conversion is complex, so that the size of the window sash material is overlarge, the sectional size of the window sash material cannot be assembled, and only the window sash material can be penetrated. Therefore, the scheme has several defects, namely, the section cavity section of the section bar is damaged to influence various indexes such as energy conservation, fire prevention, wind pressure resistance and the like of the window; 2. the structure is complex, and the use is inconvenient, so the damage rate is extremely high; 3. waste national steel resources and human resources; 4. aiming at the requirement of fireproof performance, the window cannot be automatically closed within one minute when fire disaster occurs because common people often use the window improperly. The other solution is that a simple bolt type dead bolt is arranged at the window outside the multi-point transmission lock, and the defect is that common people often forget to manually bolt in use, so that the window can not be automatically closed within one minute when a fire disaster occurs, and the window has huge potential safety hazard and is not attractive. The two schemes have the current situation that the fire-fighting equipment in China is seriously damaged due to impractical use after being assembled or is dismantled by common people, and huge losses and potential safety hazards are caused to the personal safety and property safety of the country and the individual.
