Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical technology, specifically relating to a multi-angle limiting bearing and a hinge containing the bearing. Background Technology
[0002] Current door installations require hinges to secure the door to the frame. These hinges consist of left and right hinges with through holes that fit together to fix the hinges to the door and frame respectively. After assembly, a doorstop is installed on the wall to restrict the door's opening. While this serves as a limit, the doorstop extends outwards and is prone to breaking when the door is closed too forcefully. Furthermore, people may accidentally bump into the doorstop when the door is closed, potentially causing injury or damage. Additionally, the wall-mounted doorstop takes up space and can cause repeated collisions during cleaning, leading to a loose connection between the doorstop and the wall, inconvenience, and ultimately, a shortened lifespan.
[0003] Therefore, improvements are needed to address the aforementioned technical issues. Utility Model Content
[0004] The present invention aims to overcome the defects in the prior art and provide a multi-angle limiting bearing and a hinge containing the bearing that are simple and reasonable in structure, ingenious in design, and robust in overall structure, and can limit the opening angle of a door.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-angle limiting bearing, including a shaft core and at least one limiting mechanism sleeved on the shaft core; the limiting mechanism includes a limiting ring, a first limiting plate and a second limiting plate arranged on the limiting ring; the opening limiting angle of the door is formed between the first limiting plate and the second limiting plate.
[0006] In a preferred embodiment of this utility model, the number of limiting mechanisms is 2n, and the 2n limiting mechanisms are symmetrically arranged on the shaft core.
[0007] In a preferred embodiment of this utility model, the limiting ring has a through hole for the shaft core to pass through, and the limiting ring is rotatably connected to the shaft core through the through hole.
[0008] In a preferred embodiment of this utility model, the limiting ring, the first limiting plate, and the second limiting plate are fixedly connected and integrally formed.

[0012] In a preferred embodiment of this utility model, a second arc-shaped structure is formed on the inner side of the top of the second limiting plate.

Detailed Implementation
[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] Example:
[0025] like Figures 1-2 As shown, a multi-angle limiting bearing includes a shaft core 1 and at least one limiting mechanism 10 sleeved on the shaft core 1. The limiting mechanism 10 includes a limiting ring 11 and a first limiting plate 12 and a second limiting plate 13 arranged on the limiting ring 11. The opening limiting angle of the door is formed between the first limiting plate 12 and the second limiting plate 13. This utility model has a simple structure and ingenious design. By setting a limiting mechanism on the shaft core, the two ends of the limiting mechanism are used to abut and limit the opening angle of the door, which can achieve the limiting function, making the whole structure more robust, reducing door shaking, playing a protective role, and extending the service life of the hinge.
[0026] Specifically, refer to Figure 1 The number of limiting mechanisms 10 is 2n, and the 2n limiting mechanisms 10 are symmetrically arranged on the shaft core 1. In this embodiment, n=2, and the number of limiting mechanisms 10 is 4. The selection of the number of limiting mechanisms 10 is to optimize the entire hinge mechanism structure and simplify the process. Secondly, it is to ensure that the impact of the fixed leaf 5 and the door leaf 6 on the limiting mechanism 10 is safer during use, and the opening and limiting of the door is more stable and safer.
[0027] The limiting ring 11 has a through hole 2 for the shaft core 1 to pass through, and the limiting ring 11 is rotatably connected to the shaft core 1 through the through hole 2.
[0028] The limiting ring 11, the first limiting plate 12, and the second limiting plate 13 are fixedly connected and integrally formed, which improves the structural strength and overall robustness of the entire limiting mechanism 10 and further ensures safe use.
[0029] The outer end of the first limiting plate 12 is tangent to the limiting ring 11, and the outer end of the second limiting plate 13 is tangent to the limiting ring 11. In this way, the limiting mechanism 10 will avoid touching the door strip line during rotation, thereby increasing the opening angle between the fixed leaf 5 and the door leaf 6. This makes it suitable for different usage or installation environments, ensuring reliable connection and reducing usage costs.
[0030] like Figure 3 As shown, an angle α is formed between the inner side of the first limiting plate 12 and the inner side of the second limiting plate 13, where α = 0° to 360°; specifically, in this embodiment, an angle α is formed between the inner side of the first limiting plate 12 and the inner side of the second limiting plate 13, where α = 90°.
[0031] The top inner side of the first limiting plate 12 has a first arc-shaped structure 3; the top inner side of the second limiting plate 13 has a second arc-shaped structure 4.
[0032] The fixed hinge 5 is mounted on the door frame with screws, and the door hinge 6 is mounted on the door with screws. During use, when the hinge is in the open state, the first arc-shaped structure 3 on the first limiting plate 12 abuts against the door hinge 6, and the second arc-shaped structure 4 on the second limiting plate 13 abuts against the fixed hinge 5. By setting the first arc-shaped structure 3 and the second arc-shaped structure 4, the contact area between the door hinge 6 or the fixed hinge 5 and the first limiting plate 12 and the second limiting plate 13 is increased, avoiding stress concentration caused by long-term contact between the fixed hinge 5 and the door hinge 6 and the first limiting plate 12 and the second limiting plate 13, thereby ensuring the safety of the entire hinge.
[0033] like Figures 4-5 As shown, a hinge includes a bearing 20, a fixed leaf 5 and a door leaf 6 respectively rotatably connected to the bearing 20; a first bearing sleeve 7 is installed on the fixed leaf 5; a second bearing sleeve 8 is installed on the door leaf 6; a limiting mechanism 10 is located between the first bearing sleeve 7 and the second bearing sleeve 8. When the hinge is in the open state, the first limiting plate 12 abuts against the door leaf 6, and the second limiting plate 13 abuts against the fixed leaf 5. The hinge is either a male-female hinge or a door closer hinge.
[0034] The hinge of this utility model is mainly composed of three major components: a fixed leaf piece 5, a door leaf piece 6, and a bearing 20. It optimizes the structure, simplifies the process, makes the appearance more compact and beautiful, and saves materials and reduces costs.
[0035] The end of the first bearing sleeve 7 is fitted with a bolt 9, which has a T-shaped structure. One end of the bolt 9 extends into the first bearing sleeve 7, and the other end abuts against the first bearing sleeve 7. The bolt 9 serves to protect and limit the bearing 20. The outer diameter of the first bearing sleeve 7 and the second bearing sleeve 8 is consistent with that of the limiting ring 11. This improves the overall aesthetics and avoids contact with the door strip line during rotation, making it safer to use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
[0037] Although this document uses numerous reference numerals from the figures, such as shaft core 1, through hole 2, first arc structure 3, second arc structure 4, fixing leaf 5, door leaf 6, first bearing sleeve 7, second bearing sleeve 8, bolt 9, limiting mechanism 10, limiting ring 11, first limiting plate 12, second limiting plate 13, and bearing 20, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
