Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a door and window safety baffle. Background Art

[0002] With the development of the construction industry and the growing emphasis on safety, the design and application of door and window security guards have become increasingly critical. First, from a security perspective, doors and windows, as entrances and exits to buildings, have a direct impact on the safety of occupants and property. Traditional door and window designs often focus solely on their basic functions of opening, closing, and ventilation, while neglecting to address potential safety risks. Therefore, door and window security guards have emerged to effectively prevent incidents such as unauthorized intrusion and accidental collisions through physical isolation. Secondly, the technical implementation of door and window security guards involves multiple steps, including material selection, structural design, and installation methods. Security guards are typically made of high-strength, wear-resistant materials to ensure they can withstand certain external forces without damage. Structurally, security guards must fit tightly within the door and window frames, ensuring they function properly while effectively shielding against external threats. Furthermore, ease of installation and robustness are crucial design considerations. Furthermore, with the continuous advancement of technology, the functions of door and window security guards are constantly expanding and evolving. For example, some intelligent safety barriers can be connected to security equipment such as alarm systems and monitoring systems, enabling remote monitoring and automatic alarms, further enhancing building safety. In summary, door and window safety barriers are a crucial component of building safety, and their background technology encompasses a wide range of aspects. With the increasing emphasis on safety and the continuous advancement of technology, the design and application of door and window safety barriers will become more intelligent and user-friendly, providing a more robust safeguard for people's lives and property.

[0003] For example, a Chinese utility model patent (CN201771392U) discloses a door and window safety baffle that solves the following problems: the outer base of a traditional safety baffle is large in size and requires a receiving groove to be opened in the window body for installation, which has the disadvantage of being difficult to construct and assemble, and it is even more difficult to open a receiving groove on an existing old window for installation, resulting in poor applicability.

[0004] The device includes a baffle and a switch assembly. The baffle has a joint portion and a stop portion. The joint portion can be combined with the inner window. The stop portion is provided with a baffle, and the baffle has a protruding stop edge. The stop edge can block the inner window when the inner window is closed. The switch assembly is assembled on the baffle and has a pressing portion and a holding portion. The pressing portion can press against the baffle in response to the displacement of the baffle to cause the baffle to deflect, thereby controlling the stop edge to a blocking or unblocking position. The utility model can be easily constructed and assembled on new or old windows and has better safety.

[0005] When using the above technology, we found that the following technical problems exist in the existing technology: the baffle of the device cannot be flexibly adjusted in height, which in turn limits the normal use of doors and windows and reduces the convenience of living or working. In addition, the device has no expansion structure, which makes the device appear inflexible when responding to different safety needs. Therefore, we designed a door and window safety baffle to provide another technical solution to the above technical problems. Utility Model Content

[0045] A battery is provided inside the fixing plate 12 , and the first motor 9 and the second motor 13 are both electrically connected to the battery, so that the device can be controlled by electricity, which greatly saves manpower.

[0046] The present invention provides a door and window safety baffle. The device, through the design of a lifting structure, allows the protective plate 5 of the device to be adjusted in position to adapt to different weather conditions, ventilation needs or privacy protection requirements. At the same time, it can effectively limit the opening range of windows or doors, thereby preventing children or pets from falling from heights due to curiosity or accident. This function is particularly important in high-rise buildings.

[0047] The device is designed with an expandable structure so that the safety baffle can be extended as needed, thereby adding one or more physical barriers. This helps to prevent excessive exposure to sunlight or wind while maintaining indoor ventilation, and can also provide occupants with additional escape time in an emergency.

[0048] The device uses a power structure and a limit structure design to automatically open and close the door and window safety baffles without the need for manual pushing and pulling. This not only improves the convenience of use, but is also suitable for situations where manual operation is difficult or frequent opening and closing is required. At the same time, it ensures that the door and window safety baffles remain stable when the expansion surface is opened to prevent shaking or collapse caused by wind, vibration and other factors, which helps to improve the overall stability and safety of the device.

[0049] The use process of the door and window safety baffle provided by the utility model is as follows: the user installs the device on both sides of the door and window through two fixing blocks 2, and then fixes it with bolts 3 and nuts 4. The user energizes and rotates the first motor 9, and the output end of the first motor 9 drives the worm 10 to rotate. Since one side of the worm 10 is meshedly connected with the worm wheel 11, the rotation of the worm 10 drives the worm wheel 11 to rotate, and then drives the screw 7 to rotate. Since the outer side of the screw 7 is threadedly connected to the slider 6, the rotation of the screw 7 drives the slider 6 to rise and fall, and then drives the protective plate 5 to rise and fall. Therefore, the height can be adjusted according to different environmental requirements and usage needs, so as to adapt to various complex building scenes; when the area needs to be expanded, the user energizes the second motor 13 to rotate, and the output end of the second motor 13 drives the first bevel gear 14 to rotate. Since one side of the first bevel gear 14 is meshedly connected to the second bevel gear 15, the rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate, and then drives the rotating rod 16 to rotate. The rotation of the rotating rod 16 drives the diamond-shaped rotating plate 17 to rotate, which can push up the two convex push plates 25 to slide out of the anti-slip The guard plate 5, and the rotation of the rotating rod 16 drives the one-way wheel 18 to rotate. Since one side of the limiting tooth 19 is in contact with the limiting rod 22, the limiting rod 22 can limit the rotation direction of the limiting tooth 19, so that the one-way wheel 18 can only rotate along one side of the limiting tooth 19. The limiting tooth 19 can limit the one-way wheel 18 to rotate in one direction, ensuring the rotation stability of the rotating rod 16 and the diamond-shaped rotating plate 17, and ensuring the support of the diamond-shaped rotating plate 17 to the convex push plate 25. When the convex push plate 25 needs to be retracted, the user presses the limiting rod 22 through the handle 24, so that the limiting rod 22 is disengaged from the fitting connection with the rotating shaft 20, thereby allowing the one-way wheel 18 to rotate in the reverse direction. At this time, the user rotates the second motor 13 in the reverse direction, thereby driving the diamond-shaped rotating plate 17 to rotate in the reverse direction, disengaging the fitting connection with the convex push plate 25. Under the elastic force of the tension spring 26, the two convex push plates 25 are retracted into the protective plate 5. In summary, the utility model brings significant improvements in functionality, safety, convenience and aesthetics. These advantages make the device an indispensable part of modern architecture and bring more convenience and comfort to people's lives.
