DETAILED DESCRIPTION

[0018] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a sealed normally closed fire door with a window structure comprises: a door frame 1, a fire door 2, an observation window 4 and a cooling auxiliary component; the door frame 1 is hinged with the fire door 2 through a hydraulic hinge 3, which keeps the normally closed state of the fire door 2 and can also make the closing of the fire door 2 slow and stable; the fire door 2 is provided with an observation window 4 inlaid with fireproof glass, which is convenient for escaping personnel to observe the fire situation; the door frame 1 is provided with a cooling auxiliary component; the observation window 4 on the fire door 2 is fixed A water shield 5 is provided to prevent water flow from affecting the clarity of the observation window 4. A water flow channel 6 is provided at the upper end of the water shield 5. The water flow direction of the water flow channel 6 is toward the door handle of the fire door 2 to prevent the door handle from being difficult to open due to excessive temperature. The cooling auxiliary component includes a slot 7, a fixing block 8, an empty slot 9, a limit block 10, a clamping block 11, a spring 12, a water box 13, an insert block 14, a nozzle 15, an external threaded connecting pipe 16 and a water pipe 17. The slots 7 are symmetrically arranged on both sides of the upper end of the door frame 1, and the fixing blocks 8 are symmetrically fixed and arranged at equal distances. On both sides of the upper end of the door frame 1; a slot 9 is provided in the fixed block 8, and a limit block 10 is movably engaged in the slot 9, and a block 11 is fixedly provided on the upper end of the limit block 10, and the block 11 passes through the fixed block 8, and a spring 12 is provided in the slot 9, and the spring 12 is in a compressed state, and the two ends of the spring 12 are respectively engaged with the inner wall of the slot 9 and the limit block 10 to realize the lifting of the block 11; the side ends of the water box 13 are symmetrically fixed with an insert block 14, and the slot 7 corresponds to the insert block 14 in the corresponding position and the same number of groups, and the slot 7 and the insert block 14 are provided. The plug block 14 is plugged in and used for positioning and installing the water box 13; the bottom end of the water box 13 is equidistantly installed with nozzles 15, and the water box 13 is symmetrically arranged on both sides of the door frame 1. The nozzle 15 sprays water toward the fire door 2, which is convenient for cooling the fire door 2; the water box 13 is clamped with the door frame 1, and the clamping block 11 is clamped with the water box 13 to fix the position of the water box 13; the upper end of the water box 13 is fixedly connected with an externally threaded connecting pipe 16, and the externally threaded connecting pipe 16 is connected to the water pipe 17 through a threaded sleeve, and is sealed and waterproofed.

[0020] During actual use, when a fire occurs, water from the water pipe 17 flows into the water box 13 through the externally threaded connecting pipe 16, and the nozzle 15 sprays water toward the fire door 2 to cool down the fire door 2. Part of the water falls onto the water retaining cover 5 without affecting the observation of the situation by the escaped personnel. At the same time, the water on the water retaining cover 5 flows along the water flow groove 6 to the door handle position of the fire door 2 to prevent the door handle from being too hot and making it inconvenient for personnel to operate to open the fire door 2.
