[0096] When the window needs to be opened, the button 141 is pressed by the thumb of the holding handle 27, so that the pull rod 14 moves downward along the axis direction of the connecting rod 12, the guide column 143 extrudes the inner wall of the waist hole 151 when the pull rod 14 moves, so that the extrusion block 15 moves in the horizontal direction and pushes the positioning plate 162 to move towards the installation sleeve 161, so that the end of the positioning plate 162 is completely immersed into the inside of the installation sleeve 161; thereby the positioning of the positioning plate 162 to the limiting plate 132 is released; then the handle 27 is turned, so that the handle 27 drives the connecting rod 12 to rotate, the connecting rod 12 drives the rotating sleeve 13 to move upward; so that the bottom of the limiting plate 132 moves above the inclined surface of the positioning plate 162; at the same time, the trapezoidal block 24 gradually moves away from the clamping block 25; with the movement of the rotating sleeve 13, the top of the extrusion block 15 is in contact with the bottom of the protruding ring 112, thereby the movement of the rotating sleeve 13 can be limited; then the finger pressing the button 141 is released, the extrusion block 15 is pushed to move under the rebounding force of the second elastic member 152, so that the button 141 is embedded in the handle 27, thereby the operator can observe the state of the window.

[0097] Embodiment 3

[0098] With reference to Figures 1-4 For the third embodiment of the application, which is different from the first two embodiments, it comprises that the rotating member 11 comprises a connecting plate 111 arranged on the side wall thereof; the linkage plate 26 is hingedly connected to one end of the connecting plate 111 and hingedly connected to the other end of the sliding block 23; the sliding block 23 is connected to the trapezoidal block 24; and the clamping block 25 penetrates through the fixed shell 21 and extends to the outside thereof.

[0099] In this embodiment, the number of the sliding grooves 22 is two groups, and the two groups of the sliding grooves 22 are symmetrically arranged on the inside of the fixed shell 21, and the number of the corresponding sliding blocks 23 is also two groups.

[0100] The side wall of the rotating member 11 is provided with the connecting plate 111, and the connecting plate 111 can better connect the linkage plate 26 and the sliding block 23; thereby the rotating member 11 can effectively drive the sliding block 23 to move through the rotation, and a better connecting rod transmission system can be formed.

[0101] Specifically, the clamping block 25 is a trapezoidal structure, and the inclined surface of the clamping block 25 corresponds to the direction of the operator when the window is opened; when the window is opened inward, the inclined surface of the clamping block 25 faces inward, and vice versa.

[0102] When the window is opened, the window drives the clamping block 25 to rotate, and the inclined surface of the clamping block 25 abuts against and is extruded by the groove arranged in the window frame during the rotation, so that the clamping block 25 moves towards the fixed shell 21; thereby the window can be opened.

[0103] Further, 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 the window frame 31 is internally provided with a positioning hole matched with the clamping block 25.

[0104] It should be noted that the window frame 31 is matched with the window body 32, and the window frame 31 is embedded in the wall body; the window body 32 and the window frame 31 are relatively rotatable through the hinge 33 arranged therebetween; and the window body 32 is flipped to generate a gap between the window body 32 and the window frame 31, so that the window is opened.

[0105] Specifically, the fixed shell 21 is installed on the free end side wall of the window body 32 in contact with the window frame 31, and after the fixed shell 21 and the window frame 31 are relatively fixed, the fixed shell 21 can fix the positions of the window frame 31 and the window body 32.

[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 and ensure a certain lighting effect in the room; the electromagnetic shielding layer uses embedded fine metal mesh such as copper or aluminum or glass coated with conductive metal oxide film to reflect and absorb electromagnetic waves and provide efficient electromagnetic shielding.

[0107] The sound insulation layer uses laminated glass technology, and PVB polyvinyl butyral or other efficient sound insulation film is added between two or more pieces of glass to effectively block the transmission of noise; as the fireproof layer, the intermediate layer can contain refractory materials such as ceramic fiber or special fireproof gel, which expands to form a heat shield barrier at high temperatures and delays the spread of flames.

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

[0109] Further, good sealing design not only helps to improve sound insulation performance, but also prevents external air and moisture from penetrating to ensure the stability of the internal environment.

[0110] In summary, the embedded fine metal mesh or conductive film coated glass realizes efficient electromagnetic shielding, protects sensitive electronic equipment from external interference, prevents internal signal leakage, and ensures information security; the efficient sound insulation film in the laminated glass effectively blocks noise and creates a quiet and comfortable indoor environment, especially suitable for places sensitive to sound such as hospitals and laboratories; the refractory material in the intermediate layer expands to form a heat shield barrier at high temperatures, significantly delaying the spread of flames.

[0111] It is important to note that the above examples are merely intended to illustrate the technical solutions of the present application but not to limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, and all these modifications and equivalents should be included in the scope of the claims of the present application.
