Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic shielding, especially to a shielding window suitable for a secret meeting room. BACKGROUND

[0002] In order to prevent important confidential information from being leaked, many meetings need to be held in secret meeting rooms. Secret meeting rooms are common places for holding secret meetings, and they can effectively shield sound, light, and electromagnetic signals generated during the meeting. Secret meeting rooms not only effectively prevent wireless eavesdropping, monitoring, and surveillance, but also have multiple prevention functions such as preventing eavesdropping, preventing far-infrared imaging, preventing wireless remote peeping, preventing electromagnetic radiation, preventing laser and microwave eavesdropping, and preventing direct eavesdropping risks, which can comprehensively prevent information leakage.

[0003] For conference rooms, windows are essential structures to meet ventilation needs. Windows are also places where electromagnetic shielding leaks easily. Based on the above situation, some existing technologies use whole coverage to meet the light transmission but cannot be opened. This structure avoids electromagnetic shielding leakage by optimizing the shielding efficiency of the light transmission glass. Although the shielding window in this structure ensures the shielding effect, it is not suitable for conference rooms when ventilation is needed.

[0004] Based on the above needs, the applicant has applied and disclosed a shielding window that can meet the ventilation and window closing needs (publication number CN218991413U). The opening state of the window sash and the window frame does not affect the normal use of the shielding cooperation components, or the shielding cooperation components between the window sash and the window frame do not affect the normal opening of the window sash relative to the window frame.

[0005] For the above-mentioned disclosed technology, actual use feedback shows that it has the following defects:

[0006] The shielding glass comprises a pair of symmetrically distributed and rectangular glass bodies arranged oppositely and a copper mesh clamped between the pair of glass bodies, the overall shielding effect of the shielding glass is directly affected by the shielding effect of the copper mesh, the shielding effect of the copper mesh is affected by the weaving density, the higher the weaving density, the better the shielding effect, but the light transmittance is poor, when the shielding window is in the closed state, the light transmittance cannot meet the use requirement of some conference rooms, the conference room without light can be illuminated by light, but the overall use is depressing and the comfort is poor, and the lower the weaving density, the better the light transmittance, but the shielding effect is reduced, therefore, for the shielding window, the use of the copper mesh is indispensable for switching between the open and closed states.

[0007] Therefore, for the shielding window with the above structure, the structure needs to be improved to further improve the light transmittance in the closed state and meet the reliable shielding effect requirement. Content of the utility model

[0008] The utility model discloses a shielding window suitable for secret conference room, and solves the technical problem of opening ventilation and closing shielding and enhancing light transmittance.

[0009] The shielding window suitable for secret conference room of the utility model is implemented as follows:

[0010] A shielding window suitable for secret conference room, comprising: a window sash, the window sash comprises a shielding glass in the shape of rectangle and aluminum alloy sash frames respectively arranged on four sides of the shielding glass,

[0011] The shielding glass comprises a pair of symmetrically distributed and rectangular glass bodies arranged oppositely and a copper mesh clamped between the pair of glass bodies,

[0012] The copper mesh extends from the circumferential edge of the glass body to the outside of the glass body, the aluminum alloy sash frame clamps the pair of glass bodies, and

[0013] The inner side end surface of the glass body facing the outside of the secret conference room in the pair of glass bodies is provided with a conductive film, and the conductive film partially extends to the end surface of the circumferential edge of the glass body facing the outside of the secret conference room to conduct with the aluminum alloy sash frame,

[0014] The part, where the copper mesh is clamped between the pair of glass bodies, is shaped with a plurality of light transmission holes.

[0015] In the optional implementation of the utility model, the part, where the copper mesh is clamped between the pair of glass bodies, is shaped as a honeycomb structure.

[0016] In the optional implementation of the utility model, the conductive film is a dense conductive film formed by plating ITO material on a polyester film.

[0017] In the optional implementation of the utility model, the conductive film is connected to the outer side end face and the inner side end face of the four peripheral edges of the glass body by bonding.

[0018] In the optional implementation of the utility model, the inner side end face of the glass body in the pair of glass bodies facing the outside of the secret meeting room is provided with an infrared blocking film layer.

[0019] In the optional implementation of the utility model, the main component of the infrared blocking film layer is at least one of nano-tin oxide antimony or nano-cesium tungsten bronze or nano-indium tin oxide.

[0020] In the optional implementation of the utility model, the shielding window suitable for the secret meeting room further comprises:

[0021] The window frame comprises four aluminum alloy window frames connected in sequence at the four corners of the window frame and fixed to the shielding wall; a metal mesh is arranged between each aluminum alloy window frame and the shielding wall; the copper mesh extends from the shielding glass to the clamping surface of the aluminum alloy sash frame on the side of the window frame; and

[0022] The conductive elastic member is adapted to be bonded and fixed to the metal mesh or the copper mesh; when the sash is closed relative to the window frame, the conductive elastic member is pressed between the aluminum alloy sash frame and the aluminum alloy window frame and simultaneously connects the copper mesh and the metal mesh.

[0023] In the optional implementation of the utility model, the part of the copper mesh extending out of the aluminum alloy sash frame is at least partially pressed between the sash galvanized corner strips;

[0024] The sash galvanized corner strip is a right-angle connecting piece to enable the copper mesh to be bent by 90 degrees along the sash galvanized corner strip.

[0025] In the optional implementation of the utility model, the conductive elastic member is bonded and fixed to the metal mesh by conductive glue; and

[0026] The conductive elastic member is partially bonded and fixed to the sash galvanized corner strip.

[0027] In the optional implementation of the utility model, a connecting rod and a stay component are further arranged between the window frame and the sash to enable the sash to be adapted to be opened and closed relative to the window frame.

[0028] By adopting the above technical solution, this utility model has the following beneficial effects: The shielding window of this utility model, which is suitable for confidential conference rooms, ensures the reliability of the shielding performance of the shielding glass through the cooperation of copper mesh and conductive film. In this case, due to the cooperation of conductive film, multiple light-transmitting holes can be set for the copper mesh to facilitate light transmission, thereby improving the overall light transmission effect of the shielding glass. Therefore, it can simultaneously take into account both light transmission and shielding performance, thereby meeting the light transmission and shielding requirements during the use of confidential conference rooms.

[0029] Furthermore, by using copper mesh on the window sash and metal wire mesh on the window frame, along with conductive elastic elements, when the window sash and window frame are closed, the conductive elastic elements press against the aluminum alloy sash and window frame, simultaneously connecting the copper mesh and metal wire mesh. This achieves a shielding effect when the window sash and window frame are closed. Moreover, the metal wire mesh and copper mesh are in a press-fit contact relationship, so they can separate when the window sash and window frame are open. In other words, the open state of the window sash and window frame does not affect the normal use of the shielding components, or the shielding components between the window sash and window frame do not affect the normal opening of the window sash relative to the window frame. Therefore, this shielded window allows the window sash to be opened smoothly relative to the window frame when window shielding is not required, while effectively ensuring a shielding fit between the window sash and window frame when window shielding is needed.

[0036] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further explained in detail.

[0037] Embodiment 1:

[0038] Please refer to Figures 1 to 3 As shown in the figure, the embodiment provides a shielding window suitable for secret meeting room, including: window frame fixed on shielding wall and window sash suitable for opening relative to window frame, the opening mode here can adopt for example but not limited to inclined opening mode, and the specific window frame and window sash are further provided with connecting rod wind brace assembly maturely used in prior art to make the window sash suitable for opening and closing relative to the window frame, and the structure of the specific connecting rod wind brace assembly is not absolutely limited in the embodiment, so the structure is not specifically described here.

[0039] Next, the shielding cooperation structure between the window frame and the window sash is described in detail.

[0040] Firstly, the window frame includes four corner aluminum alloy window frames 6 successively connected and enclosed around the window on the shielding wall; and the metal wire net 8 is clamped between each aluminum alloy window frame 6 and the shielding wall. The aluminum alloy window frame 6 here can be directly fixed on the shielding wall, and the aluminum alloy window frame 6 and the shielding wall can be provided with window frame galvanized corner strip 7, and the metal wire net 8 is clamped between the window frame galvanized corner strip 7 and the aluminum alloy window frame 6 on the basis of the structure. It should be noted that part of the metal wire of the metal wire net 8 can extend to the circumferential side end face of the aluminum alloy window frame 6 towards the window sash after the cooperation of the window frame galvanized corner strip 7 and the aluminum alloy window frame 6, and the conductive glue can be selected to fix the metal wire.

[0041] Secondly, the window sash includes shielding glass in rectangular shape and aluminum alloy sash frame 3 respectively provided on the four circumferential sides of the shielding glass; the shielding glass includes a pair of symmetrically distributed glass bodies 1 in rectangular shape arranged oppositely and copper net 2 clamped between the pair of glass bodies 1; the copper net 2 extends to the outside of the glass body 1 from the four circumferential edges of the glass body 1; the aluminum alloy sash frame 3 clamps the pair of glass bodies 1, and the copper net 2 extends to the outside of the aluminum alloy sash frame 3 from the clamping surface of the aluminum alloy sash frame 3 on the side of the shielding glass towards the window frame. In an alternative embodiment, sealing glue is further provided between the copper net 2 and the aluminum alloy sash frame 3.

[0042] More specifically, the copper mesh 2 extends to a position outside the aluminum alloy sash frame 3 and is at least partially compressed between the zinc-coated sash angle bars 4. In an alternative embodiment, the zinc-coated sash angle bars 4 are right-angle connectors so that the copper mesh 2 is bent by 90° along the zinc-coated sash angle bars 4. With such a structure, a portion of the copper mesh 2 can be directed towards the window frame, that is, the zinc-coated sash angle bars 4 serve to change the direction of the copper mesh 2.

[0043] Based on the above structure, in order to better achieve effective shielding of the window sash and the window frame in the closed state, the present embodiment also designs an electrically-conductive elastic member 5. The electrically-conductive elastic member 5 is adapted to be bonded and fixed with the metal mesh 8 or with the copper mesh 2; when the window sash and the window frame are closed, the electrically-conductive elastic member 5 is compressed between the aluminum alloy sash frame 3 and the aluminum alloy window frame 6 and simultaneously connects the copper mesh 2 and the metal mesh 8. That is, the electrically-conductive elastic member 5 here can be bonded and fixed with the metal mesh 8 or with the copper mesh 2. In an alternative embodiment, the electrically-conductive elastic member 5 is made of electrically-conductive foam.

[0044] The present embodiment is only in an alternative embodiment, the electrically-conductive elastic member 5 is bonded and fixed with the metal mesh 8 by means of electrically-conductive adhesive; and the electrically-conductive elastic member 5 is partially bonded and fixed on the zinc-coated sash angle bars 4. That is, the zinc-coated sash angle bars 4 achieve fixation of the electrically-conductive elastic member 5, so that the electrically-conductive elastic member 5 can maintain the stability of its structure during use.

[0045] In summary, for the shielding window of the present embodiment suitable for a confidential meeting room: through the copper mesh 2 provided on the window sash and the metal mesh 8 provided on the window frame, and in cooperation with the electrically-conductive elastic member 5, when the window sash and the window frame are closed, the electrically-conductive elastic member 5 is compressed between the aluminum alloy sash frame 3 and the aluminum alloy window frame 6 and simultaneously connects the copper mesh 2 and the metal mesh 8, thereby achieving the shielding effect of the window in the closed state of the window sash and the window frame. Furthermore, the metal mesh 8 and the copper mesh 2 adopt a compressed contact relationship, so that in the open state of the window sash and the window frame, the two can be separated, that is, the open state of the window sash and the window frame does not affect the normal use of the components forming the shielding cooperation, or the components forming the shielding cooperation between the window sash and the window frame do not affect the normal opening of the window sash relative to the window frame. Thus, the shielding window of the present utility model can smoothly open the window sash relative to the window frame when the shielding of the window is not required, and can effectively ensure the effective shielding cooperation between the window sash and the window frame when the shielding of the window is required.

[0046] On the basis of the above structure, it is next explained that, in order to enable the window sash and the window frame to have good light transmission in the closed state, meeting the light transmission requirements during use of the confidential meeting room, the present embodiment is further designed as follows:

[0047] Firstly, the copper net 2 is arranged between the pair of glass bodies 1 and is formed with a plurality of light transmission holes 21. Alternatively, the copper net 2 is arranged between the pair of glass bodies 1 and is formed with a honeycomb structure. Alternatively, the copper net 2 is arranged outside the aluminum alloy sash 3 and is formed with a honeycomb structure or other structure without the light transmission holes 21.

[0048] Further, the inner side end surface of the glass body 1 of the pair of glass bodies 1 facing the outside of the secret meeting room is provided with a conductive film 9. The conductive film 9 extends to the end surface of the circumferential edge of the glass body 1 facing the outside of the secret meeting room and is in conductive connection with the aluminum alloy sash 3. Alternatively, the conductive film 9 is connected with the outer side end surface and the inner side end surface of the circumferential edge of the glass body 1 by, for example but not limited to, conductive adhesive. In use, the conductive film 9 is in good grounding through the conductive aluminum alloy sash 3 and has good shielding effect on magnetic field and electric field.

[0049] More specifically, in an alternative embodiment, the conductive film 9 used in the present embodiment is a dense conductive film formed by coating ITO material on a polyester film. ITO material (indium tin oxide) is an n-type semiconductor material with high conductivity and high visible light transmittance.

[0050] Based on the above, the reliability of the shielding performance of the shielding glass is ensured by the cooperation of the copper net 2 and the conductive film 9. In this case, the copper net 2 is provided with a plurality of light transmission holes 21 to facilitate light transmission, thereby improving the light transmission effect of the shielding glass and meeting the light transmission and shielding requirements of the secret meeting room.

[0051] Embodiment 2:

[0052] Please refer to Figures 1 to 5 Based on the shielding window for the secret meeting room in Embodiment 1, the inner side end surface of the glass body 1 of the pair of glass bodies 1 of the shielding window for the secret meeting room in the present embodiment is provided with an infrared blocking film layer 100.

[0053] It should be noted that the infrared blocking film layer 100 used in the present embodiment is a thin film with existing infrared blocking function. The main component of the thin film for infrared blocking is nano ultrafine particles of infrared blocking substances, which can be nano antimony tin oxide (nano ATO), nano cesium tungsten bronze, nano indium tin oxide (nano ITO), or a combination of one or more of them.

[0054] The nano ultra-microparticle film of the main functional component of the infrared blocking material can significantly reduce the transmittance of infrared rays, and the nano ultra-microparticle of the infrared blocking material has weak absorption rate to visible light, so the film has good light transmittance.

[0055] In addition, the infrared blocking film layer 100 can be attached to the glass body 1 after film formation, or can be directly coated on the glass body 1 to form a film, and the present embodiment is not absolutely limited. For the method of coating the infrared blocking film layer 100 on the glass body 1, the infrared blocking film layer 100 is set to a dry and cured film layer attached to the surface of the glass body 1 by a coating process using a water-based dispersion liquid. The manufacturing method of the infrared blocking film layer 100 coated on the surface of the glass body 1

[0056] The existing mature film forming process such as flow casting method, roll coating method, spraying method, etc. is adopted. Before coating, any one or any two or three of the nano antimony tin oxide (nano ATO), nano cesium tungsten bronze, nano indium tin oxide (nano ITO) is uniformly mixed with a water-based dispersion liquid to form a film material. During coating, the film material is coated on the surface of the glass body 1 by a suitable film forming process, and the infrared blocking film layer 2 can be obtained after drying by a suitable process. The water-based dispersion liquid of the water-based system has the characteristics of environmental protection and no pollution.

[0057] In summary, for the shielding window suitable for the secret meeting room of the present embodiment, the infrared blocking film layer 100 is connected to the surface of one of the glass bodies 1, so that the glass body 1 has high blocking rate to infrared laser. Therefore, when the glass body 1 is applied to the shielding window, not only the electromagnetic wave protection performance of the secret meeting room can be enhanced, but also the risk of indoor laser eavesdropping can be reduced, thereby protecting the information security of the secret meeting room in many aspects.
