[0024] An observation window 3 is provided to facilitate observation of the environment outside the door. A shielding component 4 is also provided. The shielding component 4 is installed on the inner side of the steel door 2 to close the position of the observation window 3. At the same time, the shielding component 4 can be opened to observe through the observation window 3, thereby preventing the outside from observing the situation inside the steel door 2 through the observation window 3, thereby improving the privacy protection effect. At the same time, the steel door 2 is provided with thermal insulation material, so that the thermal conductivity of the steel door 2 is reduced when it is in use, thereby playing a role in heat insulation and improving its thermal insulation effect.
[0025] like Figure 2 and Figure 3 As shown, the shielding assembly 4 includes a first fixed block 41 and a second fixed block 44, and the first fixed block 41 and the second fixed block 44 are respectively fixedly installed on the inner side of the steel door 2, and the first fixed block 41 and the second fixed block 44 are respectively arranged on the left and right sides of the observation window 3, and the inner side of the first fixed block 41 is movably hinged with a frame 42, and a shielding plate 43 is fixedly installed inside the frame 42, and a guide column 45 is fixedly installed above the inside of the second fixed block 44, and a spring 46 and a clamping column 47 are movably sleeved on the outside of the guide column 45, and the spring 46 is arranged above the clamping column 47, and the front side of the clamping column 47 is fixedly connected with a pull plate 48 extending to the front side of the steel door 2, and the frame 42 is movably clamped inside the second fixed block 44.
[0026] When in use, the clamping column 47 is moved upward by pulling the upper plate 48 along the second fixed block 44, so that the clamping column 47 moves upward along the guide column 45 in the second fixed block 44 to compress the spring 46, so that the clamping column 47 is separated from the frame 42, and the frame 42 is pulled along the first fixed block 41 to drive the baffle plate 43 to move and open, and the external situation can be observed through the observation window 3, so that the position of the observation window 3 can be opened and closed by the baffle plate 43, which is convenient for use and prevents the outside from observing the situation inside the steel door 2 through the observation window 3, thereby improving the privacy protection effect.
[0027] like Figure 4 and Figure 5 As shown, the steel door 2 includes a frame 21 and a fixed plate 22, the frame 21 and the fixed plate 22 are fixedly connected, a fixing frame 23 is fixedly installed inside the frame 21, an inner insulation layer 24 is fixedly installed inside the fixing frame 23, and an outer insulation layer 1 25 and an outer insulation layer 2 26 are movably installed on the inner and outer sides of the fixing frame 23 respectively.
[0028] The inner insulation layer 24 and the outer insulation layer 1 25 and the outer insulation layer 26 located on the inner and outer sides of the inner insulation layer 24 are provided in the frame 21 and the fixed plate 22 to isolate the internal and external heat, reduce the heat conduction effect of the frame 21 and the fixed plate 22, and improve the heat insulation effect.
[0029] like Figure 1 As shown, the dimensions of the frame 42 are adapted to the viewing window 3 .
[0030] By matching the sizes of the frame 42 and the observation window 3 , the frame 42 can cooperate with the shielding plate 43 to close the observation window 3 , thereby improving the privacy protection effect.
[0031] like Figure 3 As shown, a clamping block corresponding to the clamping column 47 is provided on one side of the frame 42 close to the second fixing block 44 .
[0032] By setting the clamping blocks on the side of the frame 42 and cooperating with the clamping columns 47, the frame 42 can be fixed to close the observation window 3.
[0033] like Figure 2 As shown, a buffer strip that fits the inner side of the observation window 3 is movably engaged on the inner side of the frame 42 .
[0034] The sealing strip can play a buffering role when the frame 42 contacts the observation window 3 , thereby ensuring that the frame 42 fits the observation window 3 .
[0035] like Figure 4 and Figure 5 As shown, the outer insulation layer 1 25 and the outer insulation layer 2 26 are respectively connected to the inner and outer sides of the inner insulation layer 24 by gluing.
[0036] The inner insulation layer 24 is an XPS extruded insulation board, and the outer insulation layer 1 25 and the outer insulation layer 2 26 are rock wool boards.
[0037] By gluing the outer insulation layer 1 25 and the outer insulation layer 2 26 inside and outside the inner insulation layer 24, and by using the inner insulation layer 24 as an XPS extruded insulation board and the outer insulation layer 1 25 and the outer insulation layer 2 26 as a rock wool board, the durability and stability of the thermal insulation performance is ensured.
[0038] The working principle of the steel door of the openable observation window is described in detail below.
[0039] like Figures 1 to 5 As shown, when in use, the card column 47 is driven to move upward by pulling the plate 48 inside the second fixed block 44, so that the card column 47 moves upward along the guide column 45 in the second fixed block 44 to compress the spring 46, so that the card column 47 is separated from the frame 42, and the baffle plate 43 is driven to move and open by pulling the frame 42 along the first fixed block 41, and the external situation can be observed through the observation window 3. After closing the frame 42, the baffle plate 43 is used to seal the position of the observation window 3, thereby preventing the outside from observing the inside of the door through the observation window 3, thereby improving privacy. The inner insulation layer 24 and the outer insulation layer one 25 and the outer insulation layer two 26 located on the inner and outer sides of the inner insulation layer 24 are provided in the frame 21 and the fixed plate 22 to isolate the internal and external heat, thereby achieving a heat insulation effect.
