Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a fixed hinge and a door containing the same. Background Technology

[0002] With the widespread use of security doors in residences, shops, and other locations, users' demands for ease of door opening are gradually increasing. To optimize the passage experience, facilitate the movement of large items, or improve space utilization, security doors with a large opening angle have become a market hotspot.

[0003] On November 8, 2023, the applicant applied for an invention patent with publication number CN117386246A, entitled "A Hidden Hinge, a Door Including the Hinge, and a Processing Technology for the Hinge". By setting up a receiving cavity and an extended blocking part, it can improve the appearance of the hinge and increase the door opening to a certain extent to meet the daily passage needs. However, due to the constraints of the receiving cavity structure, the door cannot achieve a fully open state that fits snugly against the wall.

[0004] Such opening restrictions can cause many inconveniences in actual use. For example, when a large open space is needed or when moving extra-long or extra-wide items, a door that is not fully opened will become an obstacle and affect the flexibility of use. Therefore, the above-mentioned hinges urgently need to be optimized and improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hinge to solve the above problems.

[0006] The technical solution of this utility model is implemented as follows: a hinge, including a body, the body comprising: Install end plate one; A bushing is connected to the side of the mounting end plate. And connecting part one; The connecting part one includes a connecting part one that is connected to the mounting end plate one, and a connecting part two that is connected to the bushing; The connecting part forms a clearance groove with the bushing. The clearance groove has an open end adjacent to the mounting end plate one, and a closed end extending to the reference plane of the bushing axis and the connecting part two. The reference plane is a plane that coincides with the center line of the bushing and is perpendicular to the width direction of the mounting end plate.

[0007] Furthermore, connecting part one and connecting part two form a U-shaped structure, and the outer corner of the U-shaped structure is an arc-shaped transition angle; In this case, both connecting part one and connecting part two have a plane formed on their opposite sides.

[0008] Furthermore, the open end and the closed end form an L-shaped structure.

[0009] Furthermore, the mounting end plate is integrally formed with the bushing and the connecting part.

[0010] Furthermore, a door is also provided, including a door body, a door frame, and a moving component installed on the door body, and also including the aforementioned fixed hinge; The moving components include: Install end plate two, which is installed on the side wall of the door body; Connecting part two is connected to one side of mounting end plate two; And the shaft; The shaft is inserted into the inner wall of the connecting part two, and at least partially extends out of the connecting part two to be rotatably connected to the bushing; Among them, the upper end of the connecting part two is provided with an L-shaped extended shielding part, one end of which is connected to the mounting end plate two, and the other end can rotate with the moving component and be inserted into the closed end along the opening end of the avoidance groove. Furthermore, the second connecting part has a square frame structure and is integrally formed with the second mounting end plate and the extended shielding part.

[0011] The beneficial effects of this utility model are as follows: The closed end design provides more room for rotation by shielding the extension. When the door leaf drives the drive component to rotate, the extended shield can be fully embedded in the closed end along the receiving area without interfering with the connecting part, allowing the door leaf to be fully opened 180°, meeting the needs of moving extra-long / extra-wide items and creating a transparent and open space.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0016] Example 1: like Figures 1 to 5 As shown, this utility model discloses a hinge, including a body 1, which includes: Install end plate 11; Bushing 12 is connected to the side of mounting end plate 11; And connecting part 13; The connecting part 13 includes a connecting part 14 that is connected to the mounting end plate 11, and a connecting part 2 15 that is connected to the bushing 12; The connecting part 14 and the bushing 12 form a clearance groove 16. The clearance groove 16 has an open end adjacent to the mounting end plate 11, and a closed end 17 extending to the reference plane 5 of the shaft centerline of the bushing 12 and the connecting portion 15. The reference surface 5 is a surface that coincides with the axis of the bushing 12 and is perpendicular to the width direction of the mounting end plate 11.

[0017] By adopting the above technical solution, the closed end extending to the reference plane of the bushing axis and the second connecting part can provide more sufficient rotation space for the shielding extension, such as Figure 4 As shown, when the door leaf drives the actuating component to rotate, the extended shielding part can be completely embedded into the closed end along the receiving area without interfering with the connecting part, allowing the door leaf to be fully opened 180°, meeting the needs of moving extra-long / extra-wide items and creating a transparent and open space.

[0018] Example 2: This embodiment provides a hinge, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0019] Furthermore, the first connecting part 14 and the second connecting part 15 form an inverted triangle structure, and the outer corner of the inverted triangle structure is an arc-shaped transition angle; In this case, both the first connecting part 14 and the second connecting part 15 have a plane formed on their opposite sides.

[0020] Furthermore, the open end and the closed end 17 form an L-shaped structure.

[0021] By adopting the above technical solution, compared with ordinary straight plate or irregular connection structure, the force between the mounting end plate and the bushing can be transmitted more evenly, avoiding the breakage or deformation of the connection part caused by local stress concentration, and is suitable for long-term use of heavy doors such as security doors. The U-shaped structure and the clearance groove form a regular receiving space, ensuring that the extended shielding part is always embedded along a fixed trajectory during rotation, avoiding jamming or collision problems caused by irregular shape of the receiving area, and further improving the smoothness of opening at large angles. Meanwhile, the arc-shaped transition angle and the plane formed by the outer sides of connecting part one and connecting part two also facilitate the clamping of the hinge during processing, improving processing efficiency.

[0022] Example 3: This embodiment provides a hinge, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] Furthermore, the mounting end plate 11, bushing 12, and connecting part 13 are integrally formed.

[0024] By adopting the above technical solutions, the overall stress is more uniform, the impact and vibration resistance is stronger, and the risk of loosening or breakage is reduced.

[0025] Example 4: This embodiment provides a door, including a door body 3, a door frame 4, and a moving component 2 installed on the door body 3, and also includes the aforementioned fixed hinge; Moving component 2 includes: Install end plate 21, which is installed on the side wall of the door body 3; Connecting part 22 is connected to one side of mounting end plate 21; And the shaft; The shaft is inserted into the inner wall of the connecting part 22, and at least partially extends out of the connecting part 22 to be rotatably connected to the bushing 12; Among them, the upper end of the connecting part 22 is provided with an L-shaped extended shielding part 23, one end of which is connected to the mounting end plate 21, and the other end can rotate with the moving component 2 and be inserted into the closed end 17 along the opening end of the avoidance groove 16.

[0026] In the above technical solution, there are two sets of fixed hinges, which are arranged symmetrically at the top and bottom to match the door frame and are installed on the upper and lower sides of the door frame. Similarly, the lower end of the connecting part is also provided with an L-shaped extension that matches the lower edge of the door frame. By adopting the above technical solution, two sets of fixed hinges are symmetrically installed at the ends of the door frame sidewalls, which can evenly distribute the weight of the door to the upper and lower ends of the door frame. Relying on the large-angle opening capability of the fixed hinge structure, the door can completely fit the wall, greatly improving the flexibility of the door. The shaft is inserted into the inner wall of the connecting part and the upper and lower ends protrude. Together with two sets of fixed hinges symmetrically arranged at the top and bottom, the force on the door body is evenly distributed at the upper and lower ends of the hinge, avoiding rotation jamming or component wear caused by force on one side, and improving the smoothness of opening and closing the door. The extended shielding section can, to some extent, cover the shafts and bushings inside the hinge, preventing dust, hair, and other foreign objects from entering the hinge and causing wear, thus extending the service life of the components. At the same time, it reduces the visible hinge structure and improves the appearance of the connection between the door and the door frame.

[0027] Example 5: This embodiment provides a method that, in addition to the technical solutions included in the above embodiments, also has the following technical features.

[0028] Furthermore, the connecting part 22 has a square frame structure and is integrally formed with the mounting end plate 21 and the extended shielding part 23.

[0029] By adopting the above technical solutions, mass production can be achieved through molds, reducing the number of parts processing and assembly steps and lowering production costs.

[0030] In the above technical solution, the upper and lower ends of the mounting end plate 2 are flush with the upper and lower ends of the door body, the upper end of the extended blocking part of the upper end of the connecting part 2 is flush with the upper end of the mounting end plate 2, and the lower end of the extended blocking part of the lower end of the connecting blocking part is flush with the lower end of the mounting end plate 2.

[0031] To avoid the end plate protruding beyond the door body and causing collision interference, the side of the door is free of excess protrusions, resulting in a simpler and flatter appearance.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
