Description

Technical Field

[0001] The present invention relates to the field of marine windows, and particularly to a shielding fireproof window. Background Art

[0002] At present, shielding glass is usually selected as the shielding medium for blocking electromagnetic waves in the windows of ships. The shielding glass realizes the shielding efficiency through ITO coating. Under normal circumstances, the shielding efficiency is about 20 dB. If a shielding efficiency of 40 dB is required, multiple coatings need to be carried out. At this time, the thickness of the glass increases, the weight increases significantly, the light transmittance decreases, and the cost is high, which is not suitable for large-scale use.

[0003] If the A60 fireproof function is superimposed on the basis of the high-shielding window function, a fireproof layer needs to be added to the glass. At this time, the thickness of the glass increases again, the weight becomes heavier again, and the light transmittance is further reduced; in addition, the window frame also needs to increase the heat insulation function, which will increase the assembly difficulty between the shielding glass and the window frame, and thus the shielding performance cannot be effectively guaranteed.

[0024] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the illustrations, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, numbers, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0025] As Figure 1 shown, this embodiment provides a shielding fireproof window, which includes a main window frame 1, a fireproof window leaf mechanism, and a shielding mechanism. The main window frame 1 is a plate-like structure. The main window frame 1 is manufactured by laser cutting according to the design dimensions, and then the burrs around are removed, and the edges of the laser cutting are polished to make them flat. The main window frame 1 is flatly installed on the bulkhead, and the hollow part of the main window frame 1 corresponds to the window hole reserved on the bulkhead. For example, the main window frame 1 is rectangular, but is not limited to rectangular, and the main window frame 1 plays a supporting role for the fireproof window leaf mechanism and the shielding mechanism.

[0026] The fireproof window leaf mechanism is connected to the main window frame 1 and is movably covered on the hollow part of the main window frame 1. When the fireproof window leaf mechanism covers the hollow part, the window is in a closed state; when the fireproof window leaf mechanism is opened, the window is in a ventilated state.

[0027] The shielding mechanism is connected to the main window frame 1 and is arranged on the same side as the fireproof window leaf mechanism. The shielding mechanism is movably disposed to cover the fireproof window leaf mechanism. When the shielding mechanism is in the closed state, the shielding mechanism covers the fireproof window leaf mechanism, and at this time the window is in the shielding state; when the shielding mechanism is in the open state, the shielding mechanism releases the state of shielding electromagnetic waves. When the shielded fireproof window of this embodiment is installed on a ship, the opening methods of the fireproof window leaf mechanism and the shielding mechanism are inward-opening types, so as to avoid contact between the shielded fireproof window and seawater.

[0028] As Figure 1 and Figure 2 shown, the fireproof window leaf mechanism includes a window sash frame, a fireproof glass 2, window hinges 3 and a window locking assembly. The window sash frame is a rectangular frame, and the hollow part of the window sash frame corresponds to the hollow part of the main window frame 1. In this embodiment, the window sash frame is a split structure, and the window sash frame includes a first sash frame 4 and a second sash frame 5. An installation groove for placing the fireproof glass 2 is provided on one side of the second sash frame 5. The first sash frame 4 covers the installation groove, and the first sash frame 4 is fixedly connected to the second sash frame 5 by bolts. The first sash frame 4 is used to fix the fireproof glass 2 in the installation groove.

[0029] In order to ensure the sealing performance between the fireproof glass 2 and the window sash frame, the fireproof window leaf mechanism further includes a sealing strip 6. The sealing strip 6 is wrapped around the edge of the fireproof glass 2. When the fireproof glass 2 is installed in the window sash frame, the sealing strip 6 is located in the installation groove.

[0030] The fireproof glass 2 is composed of two tempered glasses. There is a 5-mm hollow structure between the two tempered glasses, and a fireproof liquid is injected into the hollow structure. The fireproof liquid is cured by high temperature so that the fireproof liquid and the glass form an integral body.

[0031] The number of window hinges 3 is two. The two window hinges 3 are located on one long side of the second sash frame 5 and are arranged at intervals along the long side of the second sash frame 5. The second sash frame 5 is connected to the main window frame 1 through two window hinges 3, and the second window frame is flipped to cover the main window frame 1 through two window hinges 3.

[0032] In addition, the fireproof window leaf mechanism further includes a heat insulation member 7. The heat insulation member 7 is a fireproof and heat insulation material. The heat insulation member 7 is arranged on the side of the second window frame facing the main window frame 1. When the second window frame is in the closed state, the heat insulation member 7 is pressed against the surface of the main window frame 1 by the second window frame. At this time, the heat insulation member 7 plays a role in sealing the gap between the second window frame and the main window frame 1.

[0033] The window locking assembly includes a screw rod 8, an elastic member 9, a pressing block 10 and a locking nut 11. The screw rod 8 is rotatably connected to the main window frame 1 and is located on the side of the window sash frame away from the window hinge 3. The elastic member 9 is a spring, which is sleeved on the screw rod 8. The pressing block 10 is movably sleeved on the screw rod 8 and is located above the elastic member 9. The locking nut 11 is connected to the screw rod 8 and is located on the side of the pressing block 10 away from the elastic member 9. When the window sash frame needs to be locked, the screw rod 8 is rotated, and the pressing block 10 rotates with the screw rod 8 to flip to the top of the window sash frame. At this time, the locking nut 11 is rotated, and the locking nut 11 presses the pressing block 10 downward, so that the pressing block 10 presses the window sash frame.

[0034] like Figure 1 and Figure 3 As shown, the shielding mechanism includes a shielding cover 12, a shielding hinge 13, an end seat 14, a blade 15, a spring 16 and a shielding locking assembly. The shielding cover 12 is rectangular, and there are two shielding hinges 13. The two shielding hinges 13 are located on one long side of the shielding cover 12 and are spaced apart along the long side of the shielding cover 12. The end seat 14 is connected to the main window frame 1 and is arranged around the circumference of the window sash frame. The shielding cover 12 is connected to the end seat 14 through two shielding hinges 13. The shielding cover 12 can be flipped and covered on the end seat 14 under the action of the shielding hinge 13. When the shielding cover 12 is covered on the end seat 14, the shielding cover 12 plays a role in shielding electromagnetic waves.

[0035] The insert blade 15 is vertically arranged on the main window frame 1, and the insert blade 15 is arranged around the window frame and fits with the inner side surface of the end seat 14, and the top of the insert blade 15 protrudes from the top of the end seat 14. By arranging the insert blade 15 on the inner side of the end seat 14, it is beneficial to reduce the overall design size of the shielded fireproof window. The shielding cover 12 is provided with a surrounding closed receiving groove 121 on the side facing the end seat 14, and the receiving groove 121 is used to receive the insert blade 15. A plurality of groups of springs 16 are arranged in the receiving groove 121, and each group includes two opposite springs 16, and the springs 16 are made of beryllium copper. One end of the two springs 16 is fixed to the shielding cover 12, and the other ends of the two springs 16 are bent into an arch shape, and the arched parts of the two springs 16 are close to each other. When the shielding cover 12 is covered on the end seat 14, the insert blade 15 is inserted between the two springs 16 in the receiving groove 121, and the arched parts of the two springs 16 clamp the insert blade 15 under the action of their own elasticity. The inserting blade 15 and the spring 16 form a fixing assembly, and the shielding cover 12 is tightly covered on the end seat 14 under the action of the fixing assembly. The shielding cover 12 has the function of being flexibly opened or closed under the action of the inserting blade 15 and the spring 16.

[0036] The shielding locking assembly includes a locking base 17 and a handle 18. The handle 18 is rotatably connected to the other long side of the shielding cover 12 and is located on the side facing away from the window sash frame. The locking base 17 is fixed to the top of the end seat 14. When the shielding cover 12 is covered on the end seat 14, the handle 18 is located on one side of the locking base 17. A locking tongue 181 is provided at one end of the handle 18 close to the shielding cover 12, and a clamping groove 171 is provided on the side of the locking base 17 facing the handle 18. By rotating the handle 18, the locking tongue 181 on the handle 18 can be inserted into the clamping groove 171. At this time, the handle 18 and the locking base 17 are clamped to each other, so as to achieve the purpose of locking the shielding cover 12.

[0037] As Figure 1 and Figure 4 shown, the shielding fire window further includes a limiting member 19. A limiting member 19 is provided between the second window frame and the main window frame 1. The limiting member 19 is used to keep the second window frame in an open state when the second window frame is opened, so as to prevent the second window frame from rotating randomly. Similarly, a limiting member 19 is also provided between the shielding cover 12 and the main window frame 1. The limiting member 19 is used to keep the shielding cover 12 in an open state when the shielding cover 12 is opened, so as to prevent the shielding cover 12 from rotating randomly. The limiting member 19 is obtained by selection, and the structure of the limiting member 19 here will not be elaborated.

[0038] In this embodiment, in order to ensure the normal opening and closing of the window sash frame, the distance L between the side of the window sash frame away from the window hinge 3 and the insertion blade 15 1 is not less than 60 mm. To ensure that the window sash frame can be opened by more than 90°, the distance L between the window hinge 3 and the insertion blade 15 2 should not be less than 20 mm. The distance L between the shielding cover 12 and the main window frame 1 3 depends on the vertical dimension after the window locking assembly is closed. Usually, L 3 is not less than 125 mm.

[0039] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
