[0002] Door and window hinges are crucial components connecting the door and window frame and sash, primarily enabling the opening and closing of doors and windows. In practical applications, due to manufacturing errors, installation deviations, and other factors, gaps may exist between the door and window frame and sash. These gaps can affect the overall aesthetic appearance of the doors and windows, as well as their closing function, leading to a decrease in usability.

[0003] To address the aforementioned issues, some adjustable door and window hinges have emerged in the existing technology. These hinges typically adjust the gap between the door / window sash and the frame by adjusting the position of the hinge arm. However, existing door and window hinge adjustment structures generally suffer from drawbacks such as complex structure, cumbersome adjustment operation, and limited adjustment range. Many adjustment structures rely on eccentric wheel mechanisms, which, while achieving some adjustment functionality, often have a small adjustment range, making it difficult to meet practical needs. Furthermore, the complex structure increases manufacturing costs and maintenance difficulty.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0018] Figure 1 This is one of the three-dimensional structural schematic diagrams of this utility model;

[0019] Figure 2 This is an exploded view of the present invention;

[0020] Figure 3 This is the second three-dimensional structural schematic diagram of this utility model;

[0021] Figure 4 It is a three-dimensional structure of the adjusting screw. Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 An adjustable door and window hinge is shown, including a base 1, a support arm 2, and a front arm 3 and a rear arm 4 movably connected between the base 1 and the support arm 2. An adjustment structure for adjusting the front arm 3's front and rear positions is provided between the front arm 3 and the base 1.

[0024] The base 1 is the fixed part of the hinge, usually fixed to the frame of the door or window. The support arm 2 is the movable part of the hinge, usually fixed to the sash of the door or window. The front arm 3 and the rear arm 4 are both connecting arms, which are movably connected between the base 1 and the support arm 2, forming the linkage structure of the hinge.

[0025] The forearm 3 and rear arm 4 preferably adopt a cross-X-shaped structural design and are connected in the middle by a pivot to distribute the force on the hinge, thereby improving load-bearing capacity and service life. Specifically, one end of the forearm 3 is rotatably connected to the front of the base 1, and the other end of the forearm 3 is rotatably connected to a first connecting arm 7, the other end of which is rotatably connected to a support arm 2; one end of the rear arm 4 is rotatably connected to the support arm 2, and the other end of the rear arm 4 is rotatably connected to a second connecting arm 8, the other end of which is rotatably connected to the base 1.

[0026] The core of this utility model lies in its unique adjustment structure, which can realize the forward and backward adjustment of the forearm 3 position, thereby changing the gap between the door and window sash and the frame, and improving the closure and sealing of the door and window.

[0027] The adjustment structure includes a slotted hole 11, an adjusting screw 5, and an adjusting shim 6 on the base 1. The slotted hole 11 is arranged on the base 1 in the front-to-back direction. The adjusting screw 5 passes through the slotted hole 11, and the upper part of the adjusting screw 5 is rotatably connected to the forearm 3. The lower end of the adjusting screw 5 passes through the slotted hole 11 and is fixedly connected to the adjusting shim 6. In this embodiment, the adjusting shim 6 is provided with a riveting hole 62, and the lower end of the adjusting screw 5 is fixedly connected to the riveting hole 62 by riveting.

[0028] To guide the movement of the adjusting shim 6 and improve the stability and reliability of the adjustment, a guide post 12 is provided on one side of the strip hole 11 (the indoor side in this embodiment). The adjusting shim 6 is provided with a guide opening 61, which is forked onto the guide post 12 and can rotate around the guide post 12 and move inward and outward. The guide opening 61 is preferably U-shaped, but it can also be any other shape that can cooperate with the guide post 12.

[0029] The guide fork, located on the guide post, guides the movement of the adjusting shim. Combined with the constraint of the slotted hole, it converts the rotational motion of the adjusting screw into smooth forward and backward linear motion. Its advantage is a significant improvement in the stability and reliability of the adjustment process.

[0030] More specifically, the forward and backward position of the adjusting screw 5 can be adjusted by rotating it. Specifically, during the rotation of the adjusting screw 5, on the one hand, the adjusting screw 5 and the adjusting shim 6 rotate as a whole around the guide post 12; on the other hand, since the adjusting screw 5 can only move forward and backward within the slot 11, and the guide opening 61 can both rotate around the guide post 12 and move inward and outward, the adjusting screw 5 ultimately moves forward and backward. Therefore, by rotating the adjusting screw 5, its forward and backward movement can be driven, thus adjusting the position of the forearm 3, which is convenient and stable.

[0031] The adjustment range of this adjustment structure is mainly limited by the length of the strip hole 11, and it has the advantage of a large adjustment range.

[0032] To make the structure more compact and the connection more stable, the adjusting shim 6 and the guide post 12 are located on the back of the base 1, and the forearm 3 is located on the front of the base 1.

[0033] To prevent the adjusting screw 5 from falling out of the slotted hole 11 and to ensure its stability and reliability during adjustment, the adjusting screw 5 has a first step 51 and a second step 52 arranged in a disc shape from bottom to top. The diameter of the first step 51 is smaller than the diameter of the second step 52, and the first step 51 fits into the slotted hole 11. The diameter of the first step 51 is equal to or slightly smaller than the width of the slotted hole 11. The second step 52 is used for rotatable connection with the forearm 3.

[0034] In summary, the adjustable door and window hinge disclosed in this utility model has the advantages of simple structure, convenient adjustment, and large adjustment range. It can effectively solve the shortcomings of the prior art and improve the closure and sealing performance of doors and windows.
