Description

Technical Field

[0001] The utility model belongs to the technical field of door bodies, and particularly relates to a door body with an anti-falling structure. Background Art

[0002] In traditional architectural decoration and home security, doors, as essential access points and space dividers, have always placed key design and safety considerations in their design and use. With increasing awareness of residential safety, the demand for doors is no longer limited to aesthetics and practicality; more emphasis is placed on their robustness under various conditions, particularly their ability to resist tipping over and collisions. This is particularly important for families with elderly or children, or those facing emergencies such as earthquakes.

[0003] However, most existing door designs tend to focus on the smooth opening and closing of the door leaf, its sealing performance, and its appearance, while paying insufficient attention to the door's anti-tilt structure. Conventional doors typically rely on the door frame and hinges to maintain their upright position. If subjected to strong external forces, such as heavy objects hitting, strong winds, or natural disasters like earthquakes, the door is prone to tilting or even collapsing, potentially causing not only property damage but also personal injury, especially when someone is standing behind the door, posing a particularly serious safety hazard.

[0004] Therefore, based on some of the above situations in the prior art, this application has been further designed and improved. Utility Model Content

[0005] In order to solve the above technical problems, the present invention solves them through the following technical solutions.

[0006] A door body with an anti-fall structure is equipped with a limit support, which includes a limit slider and a slide arm. A slide rail is provided above the door body, and the limit slider is mounted within the slide rail. One end of the slide arm is rotatably connected to the limit slider, and the other end is rotatably connected to the door frame. The slide rail is provided with a slide groove for mounting the limit slider, and the top of the side walls on both sides of the slide groove are provided with limit edges to prevent the limit slider from detaching. The combined design of the slide rail, the limit slider, and the slide arm not only achieves a 90° stop for the door body, but also effectively prevents the door body from tilting or collapsing due to external forces, thereby enhancing the stability and safety of the door body.

[0007] Preferably, the ratio of the length a of the limit slider to the length b of the slide rail is not less than 1 / 4, so as to ensure that the limit slider has sufficient contact length in the slide rail, enhance the load-bearing capacity and stability of the slider, make the door body more stable when under force, and effectively prevent it from falling over.

[0008] Preferably, the ratio of the width c of the slide rail to the thickness d of the door body is not less than 5 / 7. This design ensures a reasonable match between the width of the slide rail and the thickness of the door body, ensuring the strength and durability of the overall structure.

[0009] Preferably, the sliding arm is made of 304 stainless steel, which makes the sliding arm have good corrosion resistance and high strength, ensuring that the sliding arm is not easy to rust and deform during long-term use, thereby extending the service life of the limit support.

[0010] Preferably, the slide rail is made of aluminum alloy. This design helps to reduce the overall weight of the door body while maintaining the necessary strength and wear resistance.

[0011] Preferably, the door body is provided with a groove for the slide rail to be assembled, and the upper surface of the slide rail is flush with the upper surface of the door body. This design allows the slide rail to be installed flush with the surface of the door body, reducing the protrusions on the door body surface, improving the safety of use and the overall aesthetics of the door body.

[0012] Compared with the prior art, the present application has the following beneficial effects: it can effectively prevent the door body from tilting or collapsing due to external forces, thereby enhancing the stability and safety of the door body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 4 A door body with an anti-fall structure is equipped with a limit stay 200. The limit stay 200 includes a limit slider 210 and a slide arm 220. A slide rail 300 is provided above the door body 100. The limit slider 210 is mounted within the slide rail 300. One end of the slide arm 220 is rotatably connected to the limit slider 210, and the other end is rotatably connected to the door frame 110. The slide rail 300 is provided with a slide groove 301 for mounting the limit slider 210. The top of the side walls on both sides of the slide groove 301 are provided with limit edges 302 to prevent the limit slider 210 from escaping. The combined design of the slide rail 300, the limit slider 210, and the slide arm 220 not only achieves a 90° stop of the door body 100, but also effectively prevents the door body 100 from tilting or collapsing due to external forces, thereby enhancing the stability and safety of the door body 100.

[0023] To ensure the structural strength of the limit stay 200 and its ability to hold the door 100 in place when it tips over, the ratio of the length a of the limit slider 210 to the length b of the slide rail 300 is no less than 1 / 4. This ensures sufficient contact length between the limit slider 210 and the slide rail 300, enhancing the slider's load-bearing capacity and stability. This makes the door 100 more stable when subjected to stress and effectively prevents it from toppling. The ratio of the width c of the slide rail 300 to the thickness d of the door 100 is no less than 5 / 7. This design ensures a proper match between the width of the slide rail 300 and the thickness of the door 100, ensuring the strength and durability of the overall structure.

[0024] Furthermore, the slide arm 220 is made of 304 stainless steel, which makes the slide arm 220 have good corrosion resistance and high strength, ensuring that the slide arm 220 is not easy to rust and deform during long-term use, thereby extending the service life of the limit support 200. The slide rail 300 is made of aluminum alloy. This design helps to reduce the overall weight of the door body 100 while maintaining the necessary strength and wear resistance. Taking into account the actual needs under different usage environments, the contact surface between the limit slider 210 and the slide rail 300 has been specially treated to add a wear-resistant coating, which effectively reduces the loss that may be caused by long-term friction and ensures the long-term accuracy of the opening and closing action of the door body 100. This design not only reduces maintenance costs, but also extends the service life of the door body 100 and its accessories.

[0025] Furthermore, the door body 100 is provided with a groove for mounting the slide rail 300, and the upper surface of the slide rail 300 is flush with the upper surface of the door body 100. This design allows the slide rail 300 to be installed flush with the surface of the door body 100, reducing surface protrusions on the door body 100, improving user safety and the overall aesthetics of the door body 100. To accommodate diverse interior decor styles, the slide rail 300 and the limit slider 210 offer a variety of finishes, such as matte black and bright silver, in various colors and textures, allowing them to blend seamlessly with various interior door styles and satisfy users' personalized aesthetic preferences.

[0026] In order to further enhance the smoothness and quietness of the opening and closing of the door body 100, a precise ball bearing structure is adopted inside the slide rail 300, so that the friction of the limit slider 210 is greatly reduced when it moves in the slide rail 300. Even after long-term use, the door opening and closing operations can still remain light and smooth, greatly improving the user experience.

[0027] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
