Description

Technical Field

[0001] This invention relates to an aluminum alloy window, and more particularly to an aluminum alloy door and window with anti-theft function for use in the field of doors and windows. Background Technology

[0002] Traditional aluminum alloy windows typically feature a casement design and utilize a locking mechanism between the window sashes for closure and locking. However, this design is insufficient in terms of burglarproof performance. To enhance security, security grilles are often installed on the outside of the windows to improve their effectiveness. It's worth noting, however, that traditional security grilles are mostly fixed structures without an opening function. This significantly hinders the view through the aluminum alloy windows and severely impacts the aesthetics of the building's exterior.

[0003] Existing patent CN113279673B discloses a detachable aluminum alloy door and window with anti-theft function, including an outer frame, which is fixedly installed on the window body and has several through slots. The outer frame has grooves on both sides of its inner surface. An inner frame has several protrusions and is movably disposed inside the outer frame. A pair of locking mechanisms are symmetrically arranged about the central section of the outer frame and are located in the grooves on both sides of the inner surface of the outer frame. A rotary drive mechanism is fixedly installed on the inner surface of the window body and is fixedly connected to the locking mechanisms. A transmission structure is fixedly installed inside the window body and is fixedly connected to the locking mechanisms. This invention facilitates quick disassembly of aluminum alloy doors and windows while avoiding the defect of thieves being able to disassemble them from the outside. While the above patent improves the anti-theft and detachability of aluminum alloy windows, it only allows for partial disassembly and still results in significant obstruction of the view. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing aluminum alloy windows have poor anti-theft performance and the external anti-theft nets are cumbersome to operate and obstruct the view.

[0005] To address the aforementioned problems, this invention provides an aluminum alloy door and window with anti-theft function, including a window frame; the window frame is equipped with a built-in anti-theft net, the built-in anti-theft net including a mounting frame fixedly connected to the window frame, the inner end of the mounting frame having an annular groove, a pair of upper and lower opposite winding plates fixedly connected in the annular groove, a pair of anti-theft ropes symmetrically arranged and forming a grid within the mounting frame passing through the pair of winding plates, one end of each pair of anti-theft ropes being fixedly connected to the lower winding plate, the other end of each pair of anti-theft ropes extending above the upper winding plate and connected to a first winding mechanism disposed within the window frame, the first winding mechanism causing the anti-theft ropes to be in a taut or slack state by winding or releasing them;

[0006] The annular groove is equipped with a storage mechanism for storing the anti-theft rope inside the annular groove. The storage mechanism includes two pairs of traction rings that are slidably connected to the upper and lower inner walls of the annular groove and are set between a pair of winding plates. Both pairs of traction rings are set in the gap on the opposite side of a pair of anti-theft ropes. The outer end of each traction ring is fixedly connected to a horizontally set traction rope. The outer ends of the two pairs of traction ropes are connected to a pair of second winding mechanisms that are symmetrically set in the annular groove.

[0007] When storing the anti-theft rope, the first winding mechanism releases a pair of anti-theft ropes that are symmetrically arranged on the left and right, while a pair of second winding mechanisms that are symmetrically arranged on the left and right rewind the two pairs of traction ropes. The two pairs of traction ropes drive the two pairs of traction rings to move to the left and right sides of the mounting frame respectively. The two pairs of traction rings pull and squeeze the pair of anti-theft ropes distributed on the left and right into the annular groove.

[0008] In the aforementioned aluminum alloy doors and windows with anti-theft function, the built-in anti-theft net installed inside the window frame 1 achieves efficient installation and storage of the anti-theft net, combining practicality and aesthetics.

[0009] As a further improvement of this application, the window frame is provided with a first window sash and a second window sash that are slidably connected to the inner wall and are configured to open in a casement manner. The lower end of the first window sash is connected to a first screw module fixed inside the window frame, and the lower end of the second window sash is connected to a second screw module fixed inside the window frame. Both the first screw module and the second screw module are electrically connected to the same controller.

[0010] As a further improvement of this application, the controller is equipped with an anti-theft system, which includes a control module. The input terminals of the control module are respectively connected to a personnel monitoring module, a window sash monitoring module, and a timing module. The input terminals of the personnel monitoring module are respectively connected to an outdoor human proximity sensor installed on the outer wall of the window frame and an indoor human proximity sensor installed on the inner wall of the window frame. The outdoor human proximity sensor and the indoor human proximity sensor can detect the presence of personnel and the distance between personnel and the window frame. The input terminals of the window sash monitoring module are respectively connected to a first distance sensor and a second distance sensor installed on the inner wall of the window frame. The first distance sensor and the second distance sensor are used to detect the position of the first window sash and the second window sash, respectively.

[0011] The output terminals of the control module are respectively connected to the window sash distance adjustment module, the built-in anti-theft net control module, and the alarm module. The output terminals of the window sash distance adjustment module are respectively connected to the first lead screw module and the second lead screw module. The output terminals of the built-in anti-theft net control module are respectively connected to the first winding mechanism and the second winding mechanism. The output terminal of the alarm module is connected to a buzzer light installed on the outer end of the window frame.

[0012] As a further improvement of this application, the first winding mechanism includes a first winding motor disposed within the window frame and a first winding roller connected to and driven by its output shaft. The ends of a pair of anti-theft ropes that are close to each other are fixedly connected to the first winding roller and wound around its outer end. The second winding mechanism includes a second winding motor fixedly connected to the inner wall of the annular groove and a pair of upper and lower distributed second winding rollers connected to its output shaft. The traction rope is fixedly connected to the second winding roller and wound around its outer end. The second winding motor is a dual-axis motor.

[0013] As a further improvement of this application, the winding plate is a strip plate with threading holes evenly distributed along its length on its surface, and the anti-theft rope moves in an S-shape through multiple threading holes on a pair of symmetrical winding plates.

[0014] As a further improvement of this application, the traction ring includes a semi-circular ring and a sliding block integrally formed therewith. The longitudinal cross-section of the sliding block is T-shaped, and the inner wall of the annular groove is provided with a sliding groove for the sliding block to slide.

[0015] As a further improvement of this application, the anti-theft system also includes an anti-theft mode opening and closing module connected to the control module. The input end of the anti-theft mode opening and closing module is connected to an anti-theft opening and closing button, which is fixed on the inner wall of the window frame. The input end of the window sash distance adjustment module is also connected to a window sash opening button fixed on the inner wall of the window frame.

[0016] As a further improvement of this application, an acoustic sensor is fixedly connected to the outer wall of the window frame facing the outside. The anti-theft system also includes an acoustic monitoring module connected to the input terminal of the control module. The input terminal of the acoustic monitoring module is connected to the acoustic sensor, and the acoustic sensor captures the demolition sound waves. The demolition sound waves include specific sound waves emitted by the window frame, window sash frame and glass when they are impacted.

[0017] As a further improvement of this application, the anti-theft system also includes an emergency mode opening and closing module connected to the control module. The input end of the emergency mode opening and closing module is connected to an emergency start button installed on the inner wall of the window frame. When the people inside sense danger, they actively press the emergency start button, and the control module directly activates the window sash distance adjustment module and the built-in anti-theft net control module. The window sash distance adjustment module directly closes the first and second window sashes through the first screw module and the second screw module. The built-in anti-theft net control module opens the built-in anti-theft net through the first winding mechanism and the second winding mechanism.

[0018] As a further improvement to this application, the aluminum alloy doors and windows with anti-theft function include the following steps during operation:

[0019] Step 1: Activate the anti-theft system. The window sash monitoring module detects the opening status of the first and second window sashes through the first and second distance sensors. If both the first and second window sashes are closed, the operation stops; otherwise, proceed to Step 2.

[0020] Step 2: The personnel monitoring module monitors outdoor personnel outside the window using outdoor human proximity sensors to detect whether there are outdoor personnel and whether the real-time distance between the outdoor personnel and the aluminum alloy window is less than the warning distance. If there are outdoor personnel outside the aluminum alloy window and the real-time distance between the outdoor personnel and the aluminum alloy window is less than the warning distance, then proceed to step 3; otherwise, stop the operation.

[0021] Step 3: Start the timing module to time the time that outdoor personnel stay outside the warning range outside the window. If the time that outdoor personnel stay outside the range within the warning distance exceeds the set stay time threshold, then proceed to step 4; otherwise, stop the operation.

[0022] Step 4: The personnel monitoring module uses indoor human proximity sensors to detect people in the room where the aluminum alloy window is located. If there are people in the room, proceed to step 5; otherwise, proceed to step 6.

[0023] Step 5: The window sash distance adjustment module adjusts the position of the first and second window sashes through at least one of the first or second lead screw modules, so that the opening distance between the two window sashes reaches a safe distance, and then proceeds to step 7.

[0024] Step six: When there are no people in the room, the window sash distance adjustment module closes both the first and second window sashes via the first or second lead screw module, and then proceeds to step seven;

[0025] Step 7: The moving distance and moving time of the window sash are obtained through the first distance sensor, the second distance sensor and the timing module. The control module calculates the real-time moving speed of the window sash based on the moving distance and moving time. Then, the real-time moving speed is compared with the normal moving speed to determine whether the window sash is subject to resistance during the closing process. If resistance is encountered, step 8 is executed. If no resistance is encountered, the operation is stopped.

[0026] Step 8: Start the first and second winding mechanisms through the built-in anti-theft net control module, so that the anti-theft rope is arranged in a vertical grid pattern to form an anti-theft net. At the same time, the buzzer light is activated through the alarm module.

[0027] In summary, this invention, by installing a built-in anti-theft net within the window frame, eliminates the need for a separate anti-theft net on the outside of the aluminum alloy window. Furthermore, through a pair of symmetrically arranged anti-theft ropes and a first winding mechanism, the ropes, when tensioned, form a vertical grid-like anti-theft net, enabling rapid installation. A storage mechanism, including a traction ring, traction rope, and a second winding mechanism, allows for quick traction and storage of the anti-theft ropes, overcoming the cumbersome operation of traditional detachable anti-theft nets. Moreover, the stored anti-theft ropes provide a wider viewing angle from the aluminum alloy window, combining practicality and aesthetics. Attached Figure Description

[0043] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] Implementation method 1:

[0045] Figure 1-11 An aluminum alloy door and window with anti-theft function is shown, including a window frame 1; the window frame 1 is provided with a built-in anti-theft net 4, the built-in anti-theft net 4 includes a mounting frame 7 fixedly connected to the window frame 1, the inner end of the mounting frame 7 is provided with an annular groove 701, a pair of upper and lower opposite winding plates 9 are fixedly connected in the annular groove 701, a pair of anti-theft ropes 8 are passed through the pair of winding plates 9 and are arranged symmetrically on the left and right and cooperate to form a grid within the mounting frame 7, one end of each pair of anti-theft ropes 8 is fixedly connected to the lower winding plate 9, and the other end of each pair of anti-theft ropes 8 extends above the upper winding plate 9 and is connected to a first winding mechanism 10 provided in the window frame 1, the first winding mechanism 10 makes the anti-theft ropes 8 taut or slack by winding or releasing them;

[0046] An annular groove 701 is provided with a storage mechanism for storing the anti-theft rope 8. The storage mechanism includes two pairs of traction rings 11 that are slidably connected to the upper and lower inner walls of the annular groove 701 and are disposed between a pair of winding plates 9. The two pairs of traction rings 11 are disposed in the gap on opposite sides of the pair of anti-theft ropes 8. Each traction ring 11 is fixedly connected to a horizontally arranged traction rope 12 at its outer end. The outer ends of the two pairs of traction ropes 12 are connected to a pair of second winding mechanisms 13 that are symmetrically arranged on the left and right sides of the annular groove 701. When storing the anti-theft rope 8, the first winding mechanism 10 releases the pair of symmetrically arranged anti-theft ropes 8, while the pair of symmetrically arranged second winding mechanisms 13 winds up the two pairs of traction ropes 12. The two pairs of traction ropes 12 drive the two pairs of traction rings 11 to move to the left and right sides of the mounting frame 7, respectively. The two pairs of traction rings 11 pull and squeeze the pair of left and right distributed anti-theft ropes 8 into the annular groove 701.

[0047] For details, please refer to Figure 7-9 When anti-theft measures are needed, the first winding mechanism 10 and a pair of second winding mechanisms 13 are activated simultaneously. The first winding mechanism 10 winds up a pair of symmetrically arranged anti-theft ropes 8, while the pair of second winding mechanisms 13 releases two pairs of traction ropes 12. The pair of anti-theft ropes 8 gradually tighten and eventually form a vertical grid-like anti-theft net (such as...). Figure 5 As shown), during the tensioning process, a pair of anti-theft ropes 8 push two pairs of traction rings 11 to slide horizontally along the annular groove 701 and move to the middle of the mounting frame 7;

[0048] When it is necessary to open the vertical grid-like anti-theft net formed by the tension of a pair of anti-theft ropes 8, the first winding mechanism 10 and a pair of second winding mechanisms 13 are activated simultaneously. The first winding mechanism 10 releases the pair of anti-theft ropes 8 that are symmetrically arranged on the left and right, and the pair of second winding mechanisms 13 wind up the two pairs of traction ropes 12. The two pairs of traction rings 11 pull the pair of slack anti-theft ropes 8 and store them in the left and right sides of the annular groove 701, thereby realizing the opening and storage of the anti-theft net.

[0049] Compared to traditional aluminum alloy windows, this invention uses a built-in anti-theft net 4 installed inside the window frame 1, eliminating the need for a separate anti-theft net on the outside of the aluminum alloy window. Furthermore, a pair of symmetrically arranged anti-theft ropes 8 and a first winding mechanism 10 allow the ropes to be tensioned to form a vertical grid-like anti-theft net, enabling rapid installation. A storage mechanism including a traction ring 11, a traction rope 12, and a second winding mechanism 13 allows for quick traction and storage of the anti-theft ropes 8, achieving rapid opening and closing of the anti-theft net. This overcomes the cumbersome operation of traditional detachable anti-theft nets. Moreover, the retracted anti-theft ropes provide a wider viewing angle from the aluminum alloy window, combining practicality and aesthetics.

[0050] Please see Figure 6and Figure 7 The first winding mechanism 10 includes a first winding motor disposed within the window frame 1 and a first winding roller connected to and driven by its output shaft. The ends of a pair of anti-theft ropes 8 that are close to each other are fixedly connected to the first winding roller and wound around its outer end. The second winding mechanism 13 includes a second winding motor fixedly connected to the inner wall of the annular groove 701 and a pair of upper and lower distributed second winding rollers connected to its output shaft. The traction rope 12 is fixedly connected to the second winding roller and wound around its outer end. The second winding motor is a dual-axis motor and has a pair of upper and lower symmetrical output shafts.

[0051] Specifically, the first winding motor drives the first winding roller to rotate, and the first winding roller winds and releases a pair of anti-theft ropes 8. The traction rope 12 is fixedly connected to the second winding roller and wrapped around its outer end. The second winding motor winds and releases a pair of traction ropes 12 on the same side through a pair of second winding rollers distributed vertically.

[0052] Please see Figure 6 and Figure 7 The winding plate 9 is a strip plate with threading holes 901 evenly distributed along its length on its surface. The anti-theft rope 8 moves in an S-shape through multiple threading holes 901 on a pair of symmetrical winding plates 9.

[0053] Specifically, the anti-theft rope 8 moves in an S-shape through multiple threading holes 901 on a pair of symmetrical winding plates 9, so that the pair of anti-theft ropes 8 form a strip-shaped grid-like anti-theft net within the opening of the mounting frame 7.

[0054] Please see Figure 6 and Figure 8 The traction ring 11 includes a semi-circular ring 1101 and a sliding block 1102 integrally formed therewith. The longitudinal section of the sliding block 1102 is T-shaped, and the inner wall of the annular groove 701 is provided with a sliding groove 702 for the sliding block 1102 to slide.

[0055] Specifically, the semicircular ring 1101 of the traction ring 11 has a good pulling and collecting effect on the anti-theft rope 8, and the sliding block 1102 and the sliding groove 702 cooperate to make the traction ring 11 have good stability when moving laterally.

[0056] Please see Figure 2 and Figure 10 The window frame 1 is provided with a first window sash 2 and a second window sash 3 that are slidably connected to its inner wall and are in a hinged configuration. The lower end of the first window sash 2 is connected to a first screw module 5 that is fixed inside the window frame 1, and the lower end of the second window sash 3 is connected to a second screw module 6 that is fixed inside the window frame 1. Both the first screw module 5 and the second screw module 6 are electrically connected to the same controller 14.

[0057] The controller 14 is equipped with an anti-theft system, which includes a control module. The input terminals of the control module are connected to a personnel monitoring module, a window sash monitoring module, and a timing module. The input terminals of the personnel monitoring module are connected to an outdoor human proximity sensor 15 installed on the outer end of the window frame 1 and an indoor human proximity sensor 16 installed on the inner wall of the window frame 1. Both the outdoor human proximity sensor 15 and the indoor human proximity sensor 16 can detect the presence of people and the distance between people and the window frame 1. The input terminals of the window sash monitoring module are connected to a first distance sensor 19 and a second distance sensor 20 installed on the inner wall of the window frame 1. The first distance sensor 19 and the second distance sensor 20 are used to detect the positions of the first window sash 2 and the second window sash 3, respectively. The output terminals of the control module are connected to a window sash distance adjustment module, a built-in anti-theft net control module, and an alarm module. The output terminals of the window sash distance adjustment module are connected to a first lead screw module 5 and a second lead screw module 6, respectively. The output terminals of the built-in anti-theft net control module are connected to a first winding mechanism 10 and a second winding mechanism 13, respectively. The output terminal of the alarm module is connected to a buzzer light 17 installed on the outer end of the window frame 1.

[0058] For details, please refer to Figure 11 The operation of aluminum alloy doors and windows with anti-theft functions includes the following steps:

[0059] Step 1: Activate the anti-theft system. The window sash monitoring module detects the opening status of the first window sash 2 and the second window sash 3 through the first distance sensor 19 and the second distance sensor 20. If both the first window sash 2 and the second window sash 3 are closed, the operation stops; otherwise, proceed to Step 2.

[0060] Step 2: The personnel monitoring module monitors outdoor personnel outside the window through the outdoor human proximity sensor 15 to detect whether there are outdoor personnel and whether the real-time distance between the outdoor personnel and the aluminum alloy window is less than the warning distance. If there are outdoor personnel outside the aluminum alloy window and the real-time distance between the outdoor personnel and the aluminum alloy window is less than the warning distance, then step 3 is executed; otherwise, the operation is stopped.

[0061] Specifically, the warning distance is a distance value set manually. Its main criterion is whether outdoor personnel are close to the window and there is a possibility of climbing the window. It can be set as needed.

[0062] Step 3: Start the timing module to time the time that outdoor personnel stay outside the warning range outside the window. If the time that outdoor personnel stay outside the range within the warning distance exceeds the set stay time threshold, then proceed to step 4; otherwise, stop the operation.

[0063] Specifically, the dwell time threshold is a time value set manually. Long-term dwelling within the warning distance poses a safety risk, so monitoring and timing are required.

[0064] Step 4: The personnel monitoring module uses the indoor human proximity sensor 16 to detect personnel in the room where the aluminum alloy window is located. If there are personnel in the room, proceed to step 5; otherwise, proceed to step 6.

[0065] Step 5: The window sash distance adjustment module adjusts the position of the first window sash 2 and the second window sash 3 by using at least one of the first lead screw module 5 and the second lead screw module 6, so that the opening distance between the two window sashes reaches a safe distance, and then proceeds to step 7.

[0066] Specifically, when there are people inside the room, there is a certain risk of them staying there for a long time. Therefore, the opening distance of the window is reduced to a safe distance so that people cannot enter directly through the window opening, which improves the security of theft and gives people inside more reaction time. At the same time, the normal opening and ventilation of the window is maintained. In addition, there are also daily situations where people inside and outside are acquaintances and chat around the window. Therefore, the window distance is simply adjusted to a safe distance so that people outside cannot pass through directly.

[0067] Step six: When there are no people in the room, the window sash distance adjustment module closes both the first window sash 2 and the second window sash 3 through the first lead screw module 5 and the second lead screw module 6, and then proceeds to step seven;

[0068] Specifically, if there are no people indoors, but people outdoors linger within the warning distance for an extended period, posing a significant risk, the windows should be closed directly to further reduce the risk.

[0069] Step 7: The moving distance and moving time of the window sash are obtained through the first distance sensor 19, the second distance sensor 20 and the timing module. The control module calculates the real-time moving speed of the window sash based on the moving distance and moving time of the window sash, and then compares the real-time moving speed with the normal moving speed to determine whether the window sash is subject to resistance during the closing process. If resistance is encountered, step 8 is executed; if no resistance is encountered, the operation is stopped.

[0070] Specifically, the first distance sensor 19 and the second distance sensor 20 (both are infrared distance sensors) detect the movement distance of the first window sash 2 and the second window sash 3 during the movement process. The real-time module records the movement time. Then, the control module calculates the movement speed of the first window sash 2 and the second window sash 3 and compares the calculated real-time speed value with the normal speed value. The normal speed value is the movement speed of the first window sash 2 and the second window sash 3 when they are closed normally without obstruction. When there are people outside and their stay time exceeds the threshold, and the real-time closing speed of the window sash is less than the normal closing speed, it is clear that the window sash is forcibly blocked by people outside. (All devices and sensors are working normally. It should be noted that when the control module cannot receive sensor signals from any monitoring module, it automatically starts the window sash closing operation and the built-in anti-theft net opening operation to prevent people outside from damaging the sensors with tools from a distance, further improving security.)

[0071] Step 8: Start the first winding mechanism 10 and the second winding mechanism 13 through the built-in anti-theft net control module, so that the anti-theft rope 8 is arranged in a vertical grid shape to form an anti-theft net. At the same time, start the buzzer light 17 through the alarm module.

[0072] Specifically, to prevent outsiders from suddenly trying to break in and block the window from closing while it is closing, the built-in security grille 4 is activated for secondary protection, and the buzzer light 17 is activated for deterrence.

[0073] Compared to traditional aluminum alloy windows, this invention employs an anti-theft system with an outdoor human proximity sensor 15, an indoor human proximity sensor 16, and a timing module. This system monitors people outside the window and tracks their dwell time. When someone remains outside the window within a warning distance for an extended period, the indoor human proximity sensor determines if someone is inside. Based on this comprehensive assessment, the first and second lead screw modules 5 adjust the window opening distance or close the window directly, improving anti-theft performance. This also prevents the window from being closed during casual conversations between people inside and outside. Furthermore, the closing speed of the window is monitored by a first distance sensor 19, a second distance sensor 20, and the timing module to determine if someone outside might climb the window. This determines whether to activate the built-in anti-theft net 4 for secondary protection, further enhancing anti-theft performance. In summary, by using multiple sensors to monitor people inside and outside the window and selecting different anti-theft strategies (at least one of no operation, closing the window, or activating the built-in anti-theft net 4) based on the actual situation, this invention provides secondary protection and further enhances anti-theft performance.

[0074] Please see Figure 10The anti-theft system also includes an anti-theft mode opening and closing module connected to the control module. The input end of the anti-theft mode opening and closing module is connected to an anti-theft opening and closing button. The anti-theft opening and closing button is fixed on the inner wall of the window frame 1 facing the interior. A window sash opening button is also fixedly connected to the inner wall of the window frame 1 facing the interior. The window sash opening button is connected to the window sash distance adjustment module.

[0075] Specifically, the anti-theft mode is controlled by an anti-theft opening and closing button, which helps to avoid triggering alarms, automatic window movement, and opening of the built-in anti-theft mesh 4 during maintenance; at the same time, the window opening button connected to the window distance adjustment module makes it easy to adjust the window opening distance on a daily basis.

[0076] The second implementation method:

[0077] Figure 2 , Figure 12-13 An aluminum alloy door and window with anti-theft function is shown. Based on the first embodiment, an acoustic sensor 18 is fixedly connected to the outer wall of the window frame 1 facing the outside. The anti-theft system also includes an acoustic monitoring module connected to the input terminal of the control module. The input terminal of the acoustic monitoring module is connected to the acoustic sensor 18. The acoustic sensor 18 captures the characteristics of the breaking sound wave.

[0078] Specifically, the sound wave sensor 18 captures the demolition sound waves to determine whether the window has been impacted or otherwise damaged. When the sound wave monitoring module receives the demolition sound wave signal transmitted back by the sound wave sensor 18, the control module immediately starts to close the window sash, activates the built-in anti-theft net 4 and the buzzer light 17 to provide rapid and comprehensive protection. At the same time, it can provide timely protection and alarm to prevent people from standing outside the warning distance to carry out long-distance damage. It should be noted that the demolition sound waves include the specific sound waves emitted by the window frame 1, the window sash frame and the glass when they are impacted.

[0079] Please see Figure 12 and Figure 13 The anti-theft system also includes an emergency mode opening and closing module connected to the control module. The input end of the emergency mode opening and closing module is connected to an emergency start button installed on the inner wall of the window frame 1. When the people inside sense danger, they can press the emergency start button. The control module will then directly activate the window sash distance adjustment module and the built-in anti-theft net control module. The window sash distance adjustment module directly closes the first window sash 2 and the second window sash 3 through the first lead screw module 5 and the second lead screw module 6. The built-in anti-theft net control module opens the built-in anti-theft net through the first winding mechanism 10 and the second winding mechanism 13.

[0080] Specifically, by setting up an emergency mode opening and closing module and an emergency start button, it is easy to actively close the window sash and install the built-in anti-theft net 4 in an emergency, thereby improving the timeliness of protection.

[0081] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
