Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof windows, and in particular relates to a fireproof window with a switch structure. Background Art

[0002] Fireproof windows are a special type of window that, together with its frame, can meet the requirements of fire resistance stability and fire resistance integrity for a certain period of time. The main function of fireproof windows is to isolate the spread of smoke and hinder heat radiation in the event of a fire, thereby delaying the spread of fire and protecting people's lives and property. Fireproof windows are usually composed of steel window frames, steel window sashes and fireproof glass, of which fireproof glass is the core part, which can remain unchanged or cracked at high temperatures, and effectively prevent the passage of flames and heat radiation.

[0003] A Chinese patent with application number CN202320347989.8 discloses a fireproof window with stable installation, including a window frame and a window body. The window body is arranged on the inner side of the window frame. A groove is opened on the upper side of the window body near the window frame. A locking mechanism for increasing stability is provided in the groove. The locking mechanism includes a spring, a connecting block, a card block and a slider switch. The connecting block is slidably connected inside the groove. A plurality of springs are fixedly connected between the lower end of the connecting block and the bottom of the groove. A slider switch is fixedly connected to one side of the connecting block. The card block is fixedly connected to the upper end of the connecting block.

[0004] The above scheme adds a locking mechanism in addition to the ordinary lock block structure. Through the cooperation of the connecting block, the card block and the spring, the stability of the fireproof window when closed is enhanced. However, in actual use, when a fire occurs, the sliding switch and other structures provided will affect the closing of the window, and the fireproof window cannot be closed immediately. In addition, the currently existing fireproof windows require personnel to discover the fire and actively close the window to play a fire prevention role. When personnel fail to discover the fire in time, or when personnel go out to open the window for ventilation, it is easy for the fire to spread, causing property loss, etc.

[0005] In view of this, the present utility model is proposed. Utility Model Content
