[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0054] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0055] Example 1

[0056] Reference Figure 3 to Figure 5 , which is the first embodiment of the present invention, provides an electromagnetic shielding, sound insulation and fire protection window, which includes a limiting unit 1, including a rotating member 11, a connecting rod 12 arranged inside the rotating member 11, a rotating sleeve 13 arranged on the outside of the end of the connecting rod 12, a pull rod 14 passing through the inside of the connecting rod 12, an extrusion block 15 arranged at the end of the pull rod 14, and a locking member 16 arranged at the end of the extrusion block 15.

[0057] In this embodiment, the connecting rod 12 can drive the rotating sleeve 13 to move while rotating, so that the rotating sleeve 13 moves to one side of the locking member 16. The locking member 16 can limit the rotating sleeve 13, so that the rotating member 11 is fixed at an appropriate angle, and then the card block can be controlled to pass through the groove inside the window frame, so that the window can be locked and closed; at the same time, while the pull rod 14 limits the rotating sleeve 13, the end of the pull rod 14 can contact the end of the extrusion block 15 and push the extrusion block 15 to move. When the extrusion block 15 moves, it can push the pull rod 14 to move along the axial direction of the connecting rod 12, so that the end of the pull rod 14 protrudes from the surface of the handle, which can conspicuously remind the operator that the window is in a closed and locked state.

[0058] The rotating member 11 is a tubular structure with a hollow interior, and the hollow structure inside the rotating member 11 is a rectangular structure; the connecting rod 12 passes through the rotating member 11 and extends to its outside, and the end of the connecting rod 12 is adapted to the hollow structure inside the rotating member 11; thereby, the rotation of the connecting rod 12 can drive the rotating member 11 to rotate synchronously.

[0059] A protrusion is disposed on the outer wall of one end of the connecting rod 12 away from the rotating member 11 , and the connecting rod 12 and the rotating sleeve 13 can be connected via the protrusion; the rotating sleeve 13 can be driven to move while the connecting rod 12 is rotated.

[0060] The pull rod 14 is a slender rod-shaped structure, and one end of the pull rod 14 is connected to the extrusion block 15. When the pull rod 14 moves in the vertical direction, the extrusion block 15 can move in the horizontal direction; and the extrusion block 15 passes through the side wall of the rotating sleeve 13 and is limited by the hole opened inside the rotating sleeve 13, so that the extrusion block 15 moves along a specific trajectory.

[0061] The locking member 16 is composed of a trapezoidal block and a spring. When the rotating sleeve 13 moves downward, it can squeeze the trapezoidal block and compress the spring. Then, when the trapezoidal block and the rotating sleeve 13 are misaligned, the spring releases elastic potential energy to push the trapezoidal block to the surface of the bottom of the rotating sleeve 13, so that the rotating sleeve 13 can be limited by the locking member 16.

[0062] When the rotating sleeve 13 is restricted, the connecting rod 12 connected to the rotating sleeve 13 is restricted from rotating, so that the position of the rotating member 11 can be controlled to be limited.

[0063] Furthermore, the closing unit 2 includes a fixed shell 21, a slide groove 22 arranged on the inner side of the fixed shell 21, a slider 23 arranged to slide inside the slide groove 22, a trapezoidal block 24 arranged on the side wall of the slider 23, a block 25 abutting against the end face of the trapezoidal block 24, a linkage plate 26 arranged at the end of the slider 23; and a handle 27 arranged at the end of the rotating member 11; the rotating member 11 and the slider 23 are connected and linked via the linkage plate 26; the rotating member 11 is installed on the inner side of the fixed shell 21.

[0064] In this embodiment, the fixed shell 21 is provided to provide a certain support for the rotating member 11, and the rotating member 11 is in contact with the fixed shell 21. The rotating member 11 is located in a fixed position inside the fixed shell 21 and can rotate; and the rotating member 11 and the slider 23 are connected by the provided linkage plate 26. When the rotating member 11 rotates, the slider 23 can be pulled to move along the track of the slide groove 22. During the movement of the slider 23, the inclined end surface of the slider 23 will squeeze the end of the block 25, so that the block 25 can be pushed out of the fixed shell 21; so that the block 25 protrudes from the surface of the fixed shell 21; and then the block 25 is inserted into the corresponding groove to fix the position between the fixed shell 21 and the window frame.

[0065] The fixed shell 21 is a strip-shaped structure with a hollow interior. The hollow structure inside the fixed shell 21 can provide movement space for other components and ensure that the internal movement mechanism is not disturbed by the outside world.

[0066] The slide groove 22 is installed at the bottom of the inner side of the fixed shell 21 by bolt connection, and a through hole is provided on the side wall of the slide groove 22. The slider 23 is located inside the slide groove 22, and a reinforcing plate is connected to the side wall of the slider 23. The reinforcing plate can pass through the through hole and extend to the outside thereof.

[0067] At the same time, the slider 23 and the trapezoidal block 24 are connected by welding; the trapezoidal block 24 moves along the side wall of the slide groove 22, and the set trapezoidal block 24 is located on one side of the slide groove 22; the inclined end slope of the set trapezoidal block 24 can contact the end of the block 25.

[0068] During the movement of the trapezoidal block 24 , as the trapezoidal block 24 moves, its inclined end surface will come into conflict with the end of the clamping block 25 , and push the clamping block 25 to gradually penetrate the fixed shell 21 and extend outward.

[0069] It should be noted that the end of the clamping block 25 is also provided with protruding plate-like structures along both sides thereof, which can limit the clamping block 25, thereby ensuring that the clamping block 25 and the fixing shell 21 will not be separated.

[0070] The handle 27 is disposed at the end of the rotating member 11 , and the rotating member 11 is protruded from the surface of the fixed shell 21 , so that the handle 27 and the rotating member 11 can be better connected. When the handle 27 rotates, the rotating member 11 can be driven to rotate synchronously.

[0071] When in use, the staff turns the handle 27 to drive the rotating member 11 to rotate. The rotation of the rotating member 11 can drive the slider 23 to move through the linkage plate 26. The movement of the slider 23 drives the trapezoidal block 24 to move. During the movement, the end face of the trapezoidal block 24 will contact the end of the block 25 and push the block 25 to move, thereby increasing the distance that the block 25 penetrates the fixed shell 21; thereby, the block 25 can be fully adapted to the groove opened inside the window frame, thereby achieving the fixation between the fixed shell 21 and the window frame.

[0072] The connecting rod 12 rotates synchronously with the rotating member 11. The rotation of the connecting rod 12 can drive the rotating sleeve 13 set at its end to move. The locking member 16 can be compressed during the movement of the rotating sleeve 13. As the rotating sleeve 13 moves downward, the locking member 16 will not interfere with the movement of the rotating sleeve 13. When the rotating member 11 rotates to an appropriate angle, the positions of the rotating sleeve 13 and the locking member 16 are staggered. At this time, the bottom surface of the locking member 16 contacts the surface of the rotating sleeve 13 and restricts the movement of the rotating sleeve 13; while restricting the rotating sleeve 13, the locking member 16 can resist the extrusion block 15 and push the extrusion block 15 to move. The movement of the extrusion block 15 can push the end of the pull rod 14 to penetrate the surface of the handle 27, which can facilitate the operator to check that the window is in a closed state.

[0073] In summary, the present invention provides a raised button on the surface of the electromagnetic shielding window handle. When the window is fully closed, the button protrudes from the handle surface, thereby ensuring that the user can intuitively judge whether the window is fully closed and reducing the risk of misoperation. When opening the window for ventilation, it is necessary to press the button to start, which can effectively avoid the problem of the window not closing tightly due to accidental touch.

[0074] Example 2

[0075] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes: the fixed shell 21 includes a positioning sleeve 211 arranged inside the fixed shell 21; the rotating member 11 includes a raised ring 112 arranged at its end; the end of the rotating member 11 passes through the fixed shell 21 and extends to the outside thereof; the raised ring 112 is adapted to the positioning sleeve 211, and the rotating member 11 and the positioning sleeve 211 are coaxially arranged.

[0076] In this embodiment, a cylindrical positioning sleeve 211 is provided inside the fixed shell 21, and the positioning sleeve 211 is a circular ring structure with a hollow interior, and the rotating member 11 is positioned by the positioning sleeve 211, ensuring that the rotating member 11 can only rotate along the axial direction of the positioning sleeve 211; in order to further adapt the rotating member 11 to the positioning sleeve 211, a raised ring 112 is provided at the bottom thereof, and the raised ring 112 can be stuck in the inner side of the positioning sleeve 211.

[0077] Furthermore, the connecting rod 12 passes through the rotating member 11 and extends to its outside, and the connecting rod 12 rotates synchronously with the rotating member 11; the connecting rod 12 includes a protrusion 121 arranged on its side wall; the rotating sleeve 13 includes an arc groove 131 opened on its side wall, a limit plate 132 arranged at the end of the rotating sleeve 13, and a reset member 133 passing through the side wall of the rotating sleeve 13; the protrusion 121 is adapted to the arc groove 131, and the rotation of the connecting rod 12 can drive the rotating sleeve 13 to move.

[0078] It should be noted that the connecting rod 12 passes through the rotating part 11 and extends to its outside. One end thereof protrudes from the top of the rotating part 11 and can be used to connect the connecting rod 12 to the handle 27 , and the other end passes through the rotating part 11 to reach the bottom, so that the connecting rod 12 can be connected to the rotating sleeve 13 .

[0079] Specifically, the rotating sleeve 13 is a tubular structure, and the diameter of the limiting plate 132 is larger than the diameter of the rotating sleeve 13, so that the limiting plate 132 can protrude from the side wall of the rotating sleeve 13, thereby better facilitating the contact between the locking member 16 and the limiting plate 132, thereby enabling the rotating sleeve 13 to be limited; a groove is provided on the bottom inner wall of the rotating sleeve 13, and a reset member 133 is provided inside the groove, and the rotating sleeve 13 can be pushed to reset by the reset member 133.

[0080] The protrusion 121 is adapted to the arc groove 131, and when the connecting rod 12 rotates, the side wall of the protrusion 121 can be driven to squeeze the inner wall of the arc groove 131, thereby driving the rotating sleeve 13 to move along the axial direction of the connecting rod 12; thereby achieving the purpose of the connecting rod 12 rotating to drive the rotating sleeve 13 to move.

[0081] Furthermore, a guide groove 2111 is formed on the inner wall of the positioning sleeve 211 ; a limit block 1321 is provided on the side wall of the limit plate 132 ; the limit block 1321 is adapted to the guide groove 2111 ; the limit block 1321 cooperates with the guide groove 2111 to enable the rotating sleeve 13 to move in the vertical direction.

[0082] It should be noted that in order to further limit the movement direction of the rotating sleeve 13 so that the rotating sleeve 13 can move in the vertical direction, a limiting block 1321 is provided at the edge of the limiting plate 132, and the limiting block 1321 is adapted to the guide groove 2111; through the sliding cooperation between the limiting block 1321 and the guide groove 2111, the cooperation between the arc groove 131 and the protrusion 121 can enable the connecting rod 12 to drive the rotating sleeve 13 to move along the axial direction of the connecting rod 12 while rotating.

[0083] Furthermore, the pull rod 14 includes a button 141 arranged at one end thereof, a rectangular plate 142 arranged at the other end thereof, and a guide column 143 arranged on the side wall of the rectangular plate 142; the extrusion block 15 includes a waist hole 151 opened on its side wall; the rectangular plate 142 passes through the inner side of the extrusion block 15; the guide column 143 is adapted to the waist hole 151; the extrusion block 15 passes through the side wall of the rotating sleeve 13 and extends outward; the running planes of the rotating sleeve 13 and the pull rod 14 are perpendicular.

[0084] It should be noted that the pull rod 14 passes through the connecting rod 12 and extends to the outside thereof, and one end of the pull rod 14 extends to the inside of the rotating sleeve 13 , and the other end thereof passes through the outside of the top of the rotating member 11 .

[0085] Specifically, a groove structure is provided inside the extrusion block 15, a rectangular plate 142 passes through the inside of the extrusion block 15, and guide columns 143 extend to both sides of the inner wall of the rectangular plate 142 that is flush with the extrusion block 15, and the guide columns 143 pass through the waist hole 151 and extend into the inside thereof; and the waist hole 151 is inclined at a certain angle, so that the movement of the pull rod 14 in the vertical direction can drive the extrusion block 15 to move in the horizontal direction.

[0086] Furthermore, the locking member 16 is arranged on the inner side of the fixed shell 21, and the locking member 16 passes through the positioning sleeve 211 and extends into the interior thereof; the locking member 16 includes a mounting sleeve 161, a positioning plate 162 arranged on the inner side of the mounting sleeve 161, and a first elastic member 163 arranged at the end of the positioning plate 162; the bottom surface of the positioning plate 162 can contact the surface of the limiting plate 132, thereby realizing the limitation of the rotating sleeve 13.

[0087] It should be noted that the mounting sleeve 161 is installed at the inner bottom of the fixed shell 21, and the mounting sleeve 161 passes through the positioning sleeve 211 and extends to its outside, and the arranged mounting sleeve 161 can provide a guide for the movement of the positioning plate 162, so that the positioning plate 162 can move along the inner wall of the mounting sleeve 161 after being compressed; the positioning plate 162 is a trapezoidal structure, and when the limit plate 132 moves downward in the vertical direction, the limit plate 132 can contact with the inclined surface of the positioning plate 162 and push the locking member 16 to move in the horizontal direction.

[0088] Furthermore, the extrusion block 15 also includes a second elastic member 152 disposed therein; one end of the second elastic member 152 is connected to the inner wall of the extrusion block 15, and the other end thereof abuts against the inner wall of the rotating sleeve 13; the end of the extrusion block 15 abuts against the end of the positioning plate 162.

[0089] It should be noted that a second elastic member 152 is provided inside the extrusion block 15, and the extrusion block 15 can be driven to reset by the setting; when the extrusion block 15 is squeezed by the locking member 16, it will compress the second elastic member 152, so that the second elastic member 152 is in a compressed energy storage state.

[0090] Specifically, the elastic coefficient of the first elastic member 163 is greater than the elastic coefficient of the second elastic member 152; when the first elastic member 163 releases elastic potential energy so that the end of the positioning plate 162 contacts the extrusion block 15, it can push the extrusion block 15 to move toward the direction close to the rotating sleeve 13, thereby making the second elastic member 152 in a compressed energy storage state.

[0091] Furthermore, the handle 27 is sleeved on the outer side of the end of the connecting rod 12, and the handle 27 rotates synchronously with the connecting rod 12; the pull rod 14 passes through the handle 27 and extends to the outside thereof; the button 141 can protrude from the surface of the handle 27.

[0092] It should be noted that the handle 27 is sleeved on the end of the connecting rod 12 , and a rectangular groove matching the outside of the connecting rod 12 is provided inside the handle 27 , so that the handle 27 can rotate synchronously with the connecting rod 12 .

[0093] Specifically, a groove is provided on the surface of the handle 27, and the button 141 is matched with the groove. When the button 141 is pressed down, the button 141 can be immersed in the groove and flush with the surface of the handle 27; the part of the button 141 protruding from the handle 27 can more prominently remind the operator of the opening and closing status of the window.

[0094] During use, when the staff needs to close the window, the operator holds the handle 27, and then turns the handle 27 to drive the rotating member 11 to rotate, so that the rotation of the rotating member 11 drives the slider 23 linked to it to move, and the slider 23 moves along the inner wall of the slide groove 22 while driving the trapezoidal block 24 to move. As the trapezoidal block 24 moves, its end face squeezes the end of the block 25 and pushes the block 25 to move. When the handle 27 is rotated to an appropriate position, the block 25 also penetrates the fixed shell 21 by an appropriate distance, and the block 25 cooperates with the groove opened inside the window frame, so that the position of the fixed shell 21 and the position between the window frame can be fixed.

[0095] When the rotating member 11 rotates, the connecting rod 12 can be driven to rotate. The rotation of the connecting rod 12 drives the protrusion 121 provided on its side wall to squeeze the inner wall of the arc groove 131, thereby driving the rotating sleeve 13 to move in the vertical direction. During the movement, the rotating sleeve 13 drives the extrusion block 15 provided inside it to move downward synchronously. During the movement, the bottom of the rotating sleeve 13 contacts the inclined surface of the positioning plate 162, and squeezes the positioning plate 162 to one side to move, so that the positioning plate 162 moves toward the inside of the installation sleeve 161. During the movement, the positioning plate 162 continuously compresses the first elastic member 163. When the rotating sleeve 13 moves to the position below the positioning plate 162, the positions of the rotating sleeve 13 and the positioning plate 162 are staggered. At this time, the first elastic member 163 releases its elastic potential to push the positioning plate 162. It moves in the direction close to the rotating sleeve 13; then the bottom surface of the positioning plate 162 contacts the surface of the limiting plate 132 and limits the limiting plate 132; while the positioning plate 162 moves, it pushes the extrusion block 15 to move, so that the extrusion block 15 moves in the direction close to the rotating sleeve 13. As the extrusion block 15 continues to move, the second elastic member 152 is in a compressed state, and then the extrusion block 15 moves to push the pull rod 14 to move along the axial direction of the connecting rod 12, so that the button 141 protrudes from the surface of the handle 27; thereby, it is more intuitive and convenient for the operator to go through the opening and closing state of the window; and since the position of the rotating sleeve 13 is fixed, the rotating member 11 is fixed, so that the block 25 is fixed inside the groove, thereby achieving the purpose of locking the window closed.

[0096] When the window needs to be opened, the user holds the handle 27 and uses the thumb to press the button 141, so that the pull rod 14 moves downward along the axis of the connecting rod 12. While the pull rod 14 moves, the guide column 143 squeezes the inner wall of the waist hole 151, so that the squeezing block 15 moves horizontally and pushes the positioning plate 162 to move toward the installation sleeve 161, so that the end of the positioning plate 162 is completely immersed in the inner side of the installation sleeve 161; thereby releasing the positioning plate 162 from limiting the position of the limiting plate 132; and then rotating the handle 27, so that the handle 27 drives the connecting rod 12 to rotate, and the connecting rod 12 is connected to the window. The rotation of the rod 12 drives the rotating sleeve 13 to move upward, so that the bottom of the limit plate 132 moves to above the inclined surface of the positioning plate 162; at the same time, the trapezoidal block 24 gradually moves away from the blocking block 25; as the rotating sleeve 13 moves, the top of the extended extrusion block 15 contacts the bottom of the raised ring 112, thereby limiting the movement of the rotating sleeve 13; then the finger pressing the button 141 is released, and the extrusion block 15 is pushed to move under the rebound force of the second elastic member 152, so that the button 141 is embedded in the handle 27, which makes it easier for the operator to observe the status of the window.

[0097] Example 3

[0098] Reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, is different from the previous two embodiments in that: the rotating member 11 includes a connecting plate 111 arranged on its side wall; one end of the linkage plate 26 is hinged to the connecting plate 111, and the other end thereof is hinged to the slider 23; the slider 23 is connected to the trapezoidal block 24; the clamping block 25 penetrates the fixed shell 21 and extends to the outside thereof.

[0099] In this embodiment, there are two groups of slide grooves 22 , which are symmetrically arranged on both sides of the interior of the fixed shell 21 , and there are also two groups of sliders 23 corresponding thereto.

[0100] The side wall of the rotating member 11 is provided with a connecting plate 111, through which the linkage plate 26 and the slider 23 can be better connected; thus, the slider 23 can be effectively driven to move by the rotation of the rotating member 11, and a better connecting rod transmission system can be formed.

[0101] Specifically, the block 25 is a trapezoidal structure, and the inclined surface of the block 25 corresponds to the operator's operating direction when opening the window; when opening inward, the inclined surface of the block 25 faces inward, otherwise, it faces outward.

[0102] When the window is opened, the window drives the block 25 to rotate. During the rotation, the inclined surface of the block 25 contacts the groove provided inside the window frame and is squeezed so that the block 25 moves toward the fixed shell 21, thereby opening the window.

[0103] Furthermore, the protection unit 3 includes a window frame 31, a window body 32 matched with the window frame 31, and a hinge 33 connecting the window frame 31 and the window body 32; the fixed shell 21 is arranged on the side wall of the window body 32; and a positioning hole matched with the block 25 is opened inside the window frame 31.

[0104] It should be noted that the window frame 31 is adapted to the window body 32, and the window frame 31 is embedded in the wall; the window body 32 and the window frame 31 can rotate relative to each other through the hinges 33; by pulling the window body 32 to flip, a gap is generated between the window body 32 and the window frame 31, so as to achieve the purpose of opening the window.

[0105] Specifically, the fixing shell 21 is installed on the free end side wall where the window body 32 contacts the window frame 31 . When the fixing shell 21 and the window frame 31 are relatively fixed, the position between the window frame 31 and the window body 32 can be fixed.

[0106] Preferably, the window body 32 includes a frame, a sealing strip, an electromagnetic shielding layer, a sound insulation layer and a fireproof layer; the frame is mainly used to support the glass to ensure a certain lighting effect in the room; for the electromagnetic shielding layer, glass embedded with a fine metal mesh such as copper, aluminum, etc. or coated with a conductive metal oxide film is used to reflect and absorb electromagnetic waves, providing efficient electromagnetic shielding.

[0107] The sound insulation layer adopts laminated glass technology, adding PVB polyvinyl butyral or other high-efficiency sound insulation film between two or more pieces of glass to effectively block the spread of noise; as a fireproof layer, the middle layer can contain fire-resistant materials such as ceramic fibers or special fireproof gels, which expand at high temperatures to form an insulation barrier and delay the spread of flames.

[0108] The frame is made of high-strength, non-deformable metal material, preferably stainless steel or aluminum alloy; to ensure structural stability and durability; at the same time, the metal frame itself can also enhance the electromagnetic shielding effect; special fireproof sealing strips are installed around the frame, which can expand and fit tightly to the window frame when a fire occurs, preventing smoke and flames from invading the room.

[0109] Furthermore, a good sealing design not only helps to improve the sound insulation performance, but also prevents the penetration of outside air and moisture, ensuring the stability of the internal environment.

[0110] In summary, efficient electromagnetic shielding is achieved by embedding fine metal mesh or glass coated with conductive film, protecting sensitive electronic equipment from external interference, preventing internal signal leakage, and ensuring information security; the efficient sound insulation film in laminated glass effectively blocks noise, creating a quiet and comfortable indoor environment, which is particularly suitable for sound-sensitive places such as hospitals and laboratories; the refractory material in the middle layer expands at high temperature to form an insulating barrier, significantly delaying the spread of flames.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
