Technical Field
[0001] The utility model belongs to the technical field of hinges, and particularly relates to a concave-convex adjustable door opening positioning structure. Background Art
[0002] In modern architectural design, the stability and safety of doors play a crucial role. Although the traditional hinge structure is simple and easy to use, it has significant deficiencies in the positioning and fixing of doors. These deficiencies not only lead to instability when the door is opened, but also may cause the door to open accidentally due to external forces, thus posing a threat to safety. In addition, the existing door positioning systems usually lack sufficient adjustment functions and cannot effectively meet the needs in different usage scenarios, especially in public environments where the door needs to be opened and closed frequently.
[0003] Most current technologies rely on simple hinge mechanisms and cannot achieve precise positioning of the door in different opening states. This not only affects the user experience of the door, but also may cause users to make misoperations in daily operations. For example, when a user tries to open the door at a specific angle, the traditional structure may not provide enough support, resulting in the door rebounding or closing, causing inconvenience and potential danger. In addition, after the door is closed, the lack of an effective fixing mechanism may cause the door to open accidentally under the influence of external forces, increasing the safety hazard.
[0004] In view of this, overcoming the above-mentioned defects of the existing technologies is an urgent problem to be solved in this technical field. Summary of the Utility Model
[0005] Aiming at the technical problems mentioned in the background art, the purpose of the utility model is to provide a concave-convex adjustable door opening positioning structure which, through the design of multiple positioning surfaces, enables the door to be accurately positioned in different opening states, avoids misoperations, improves the overall stability, makes the door more stable and safe during use, and the design of the groove and the convex block ensures that the door can be stably fixed after being closed and is not easily opened again due to external forces, so as to solve the technical problems mentioned in the above background art.

Detailed implementation manners
[0018] As Figures 1 to 4 shown, a concave-convex adjustable door opening positioning structure includes a first cover plate 10 and a second cover plate 20. A rotating rod 30 is connected between the first cover plate 10 and the second cover plate 20, so that the first cover plate 10 and the second cover plate 20 are hinged. During use, the first cover plate 10 is clamped on the door frame, and the second cover plate 20 is clamped on the door panel. Through the relative movement between the first cover plate 10 and the second cover plate 20, the effect of stable door opening and closing is achieved.
[0019] During specific implementation, one end of the first cover plate 10 facing the second cover plate 20 is provided with a first connecting plate portion 11, and one end of the second cover plate 20 facing the first cover plate 10 is provided with a second connecting plate portion 21. The first connecting plate portion 11 and the second connecting plate portion 21 are arranged opposite to each other up and down. A first connecting through hole 111 is formed on the surface of the first connecting plate portion 11, and a second connecting through hole 211 is formed on the surface of the second connecting plate portion 21. The first connecting through hole 111 corresponds to the second connecting through hole 211, and the rotating rod 30 passes through the first connecting through hole 111 and the second connecting through hole 211 for connection, so that the first cover plate 10 and the second cover plate 20 are hinged. The structure is simple and the installation is convenient.
[0020] During specific implementation, an adjustment connection groove 22 is provided in the middle of the second cover plate 20. The adjustment connection groove 22 communicates with the second connection through hole 211. An adjustment screw rod 40 is connected in the adjustment connection groove 22. The end of the adjustment screw rod 40 abuts against the upper part of the rotating rod 30. The upper part of the rotating rod 30 is respectively provided with a first positioning surface 31, a second positioning surface 32 and a third positioning surface 33. The second positioning surface 32 and the third positioning surface 33 are inclined relative to each other on both sides of the first positioning surface 31, forming different contact positioning angles. During use, when the adjustment screw rod 40 is positioned and abutted against the first positioning surface 31, it ensures that the door can accurately stay at a predetermined position when closed, preventing the door from shaking. When the door is opened outwards, the adjustment screw rod 40 is positioned and abutted against the second positioning surface 32, allowing the door to be stably opened within a certain angle, enhancing the flexibility of opening the door. When the door is opened inwards, the adjustment screw rod 40 is positioned and abutted against the third positioning surface 33, also ensuring that the door can stably stay at the required inward-opening position. Through the design of multiple positioning surfaces, the door can be accurately positioned in different opening states, avoiding misoperation, improving the overall stability, and making the door more stable and safe during use.
[0021] During specific implementation, a positioning groove 112 is recessed in the upper rear part of the first connecting plate portion 11. The front part of the second connecting plate portion 21 is provided with a positioning protrusion 212 adapted to the positioning groove 112. The positioning protrusion 212 is clamped in the positioning groove 112 for positioning connection to achieve precise positioning. When the door is closed, the positioning protrusion 212 automatically enters the positioning groove 112 to form a snap fit. At this time, the door body is stable, reducing the risk of accidental opening. The design of the groove and the protrusion ensures that the door can be stably fixed after being closed and is not easily opened again due to external forces. This structure provides additional safety protection for the door, especially in situations where it is necessary to prevent children or pets from accidentally opening the door.
[0022] During specific implementation, arc-shaped positioning edges 113 are respectively provided on both sides of the positioning groove 112. The edge of the positioning protrusion 212 is provided with an arc-shaped positioning arc surface 213. The positioning arc surface 213 is in arc fit with the positioning arc edge 113. During use, the positioning protrusion 212 slides into the positioning groove 112 along the positioning arc edge 113. The arc design ensures the smoothness of this process, avoiding jamming or excessive resistance. When opened, the positioning protrusion 212 can easily slide out of the positioning groove 112, realizing unobstructed opening and closing, and being stable and convenient to use.
[0023] In summary, a rotating rod 30 is connected between the first cover plate 10 and the second cover plate 20. An adjusting screw rod 40 is connected to the middle of the second cover plate 20. The end of the adjusting screw rod 40 abuts against the upper part of the rotating rod 30. A positioning groove 112 is provided on the upper part of the first cover plate 10, and a positioning convex block 212 is provided on the front part of the second cover plate 20. The positioning convex block 212 is clamped in the positioning groove 112 for positioning connection. The concave-convex adjustable door positioning structure of the present utility model enables the door to be accurately positioned in different opening states through the design of multiple positioning surfaces, avoiding misoperation, improving the overall stability, making the door more stable and safe during use, and the design of the groove and the convex block ensures that the door can be stably fixed after being closed and is not easily reopened due to external force.
