Description

Technical Field

[0001] This utility model relates to the field of hinge device technology, specifically a high load-bearing hinge structure. Background Technology

[0002] A hinge structure refers to a special mechanical connection that fixes two or more objects together, allowing them to rotate or fold around an axis. Common hinge structures include butterfly hinges, flat hinges, and latch hinges, which are characterized by flexibility, stability, reliability, and space saving. However, existing hinge structures often have certain problems, such as:

[0003] Application number CN2020211867.7, entitled "A High-Strength Hinge Structure," includes a hinge frame, a hinge plate, and a hinge shaft. The hinge frame has a hinge frame bushing on its side, and the hinge plate has a hinge plate bushing on its side. Multiple hinge frame bushings and hinge plate bushings are provided. In the installed state, the hinge frame bushings and hinge plate bushings are spaced apart, and a friction-reducing device is installed between the hinge frame bushings and the hinge plate bushings.

[0004] The hinge shaft is inserted into the hinge frame bushing and the hinge plate bushing. With increasing public awareness of security, more and more consumers tend to choose heavier, more protective security doors during renovations. However, this hinge structure often cannot withstand high loads and is prone to deformation or even breakage during long-term use. This not only seriously threatens the security of the security door but also greatly shortens its service life, failing to meet the basic requirements of daily use. Therefore, a high-load-bearing hinge structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-load-bearing hinge structure to solve the problem mentioned in the background art that the existing hinge structure cannot withstand high loads and is prone to deformation or even breakage during long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a first hinge base and a second hinge base, wherein the left end of the first hinge base is rotatably connected to a first support frame, and the right end of the first hinge base is rotatably connected to a first auxiliary bracket; the left end of the second hinge base is rotatably connected to a second auxiliary bracket, and the right end of the second hinge base is rotatably connected to a second support frame.

[0007] The above technical solution enhances the overall load-bearing capacity of the hinge.

[0008] As a preferred embodiment of this utility model, the first auxiliary support and the second auxiliary support are rotatably connected by a rotating shaft.

[0009] By adopting the above technical solution, it is easy to effectively disperse and absorb impact force, avoid the hinge structure from deforming or breaking due to high load, and further improve the durability and safety of the hinge.

[0010] As a preferred embodiment of this utility model, the second support frame is rotatably connected to the first auxiliary support frame via a rotating shaft.

[0011] By adopting the above technical solution, the hinge can distribute the force more evenly when subjected to external force, thereby further improving the hinge's resistance to deformation and fracture.

[0012] As a preferred embodiment of this utility model, the right end of the first support frame is rotatably connected to a first rotating rod, and the first rotating rod is rotatably connected to a bearing column; the first rotating rod is rotatably connected to the second support frame.

[0013] By adopting the above technical solution, when the hinge is subjected to external force, the external force can be effectively transmitted and dispersed through the synergistic action of the No. 1 support frame, the No. 1 rotating rod and the load-bearing column, thereby enhancing the overall stability and load-bearing capacity of the hinge structure.

[0014] As a preferred embodiment of this utility model, a load column is slidably connected to the lower end of the bearing column, and a first return spring is fixedly connected to the inner bottom surface of the load column; the upper end surface of the first return spring is fixedly connected to the lower end surface of the load column.

[0015] By adopting the above technical solution, the load column can slide along the bearing column when the load changes, and the elastic action of the first return spring can effectively buffer and absorb the impact force generated by the load, thereby protecting the hinge structure from damage. At the same time, this design can also ensure that the hinge remains stable when bearing heavy loads and extend its service life.

[0016] As a preferred embodiment of this utility model, a baffle is fixedly connected to the outer end face of the upper side of the load column, and the baffle is symmetrically arranged about the center of the load column; a second return spring is fixedly connected to the inner top surface of the baffle.

[0017] By adopting the above technical solution, the baffle can limit the displacement range of the load column during the rising or falling process, preventing it from moving excessively and detaching from the load column. At the same time, the setting of the second return spring can further enhance the buffering effect. When the load column is subjected to external force, the second return spring can undergo elastic deformation to absorb and disperse the impact force, further protecting the safety and stability of the hinge structure. This design not only improves the load-bearing capacity of the hinge, but also enhances its ability to adapt to complex load environments.

[0018] As a preferred embodiment of this utility model, the tail end of the load column is rotatably connected to a second rotating rod, and the second rotating rod is rotatably connected to the first auxiliary bracket; both the first hinge base and the second hinge base are fixedly connected to a movable plate by stud assembly.

[0019] By adopting the above technical solution, the overall rigidity and stability of the hinge structure are enhanced, enabling it to better withstand the challenges of heavy loads and complex load environments.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By distributing the weight of the door body in different directions through the No. 1 hinge base and the No. 2 hinge base, the load-bearing capacity of the hinge structure is effectively improved; the setting of the No. 1 support frame and the No. 1 auxiliary bracket, as well as the setting of the No. 2 support frame and the No. 2 auxiliary bracket, not only enhances the stability of the hinge structure, but also provides a more uniform support force when the door is opened or closed, avoiding deformation or breakage caused by excessive force at a single point; in addition, this design makes the hinge structure more flexible and can adapt to security doors of different weights and sizes, meeting consumers' high requirements for the security and durability of security doors.

[0021] When the hinge structure is subjected to external forces, hinge bases one and two, as the main support points, effectively disperse and absorb impact forces through the coordinated rotation of support frame one, auxiliary support one, auxiliary support two, and support frame two. The rotational connection between auxiliary support one and auxiliary support two allows the hinge to adjust its posture more flexibly when subjected to lateral forces, reducing stress concentration and preventing deformation or breakage. This further enhances the hinge's resistance to deformation, enabling it to maintain a stable structural form when subjected to forces in various directions.

[0022] The rotational connection between the No. 1 rotating rod on the No. 1 support frame and the load-bearing column is an important force transmission and dispersion point in the hinge structure. When an external force is applied to the hinge, the No. 1 support frame, the No. 1 rotating rod, and the load-bearing column work together to effectively transmit the external force to the load-bearing column. The impact force is buffered and absorbed through the sliding of the load-bearing column on the load-bearing column and the elastic action of the No. 1 return spring. This design not only improves the load-bearing capacity of the hinge, but also makes it more stable and reliable when facing complex load environments. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1-5 The present invention provides a high load-bearing hinge structure, comprising a first hinge base 1 and a second hinge base 2. The left end of the first hinge base 1 is rotatably connected to a first support frame 3, and the right end of the first hinge base 1 is rotatably connected to a first auxiliary bracket 4. The left end of the second hinge base 2 is rotatably connected to a second auxiliary bracket 5, and the right end of the second hinge base 2 is rotatably connected to a second support frame 6, thereby enhancing the overall load-bearing capacity of the hinge.

[0031] The No. 1 auxiliary support 4 and the No. 2 auxiliary support 5 are connected by a rotating shaft, which facilitates the effective dispersion and absorption of impact force, and prevents the hinge structure from deforming or breaking due to high load, thereby further improving the durability and safety of the hinge.

[0032] The right end of the first support frame 3 is rotatably connected to the first rotating rod 7, and the first rotating rod 7 is rotatably connected to the bearing column 8; the first rotating rod 7 is rotatably connected to the second support frame 6, which makes it easier for the hinge to distribute the force more evenly when it is subjected to external force, and further improves the hinge's resistance to deformation and fracture.

[0033] The right end of the first support frame 3 is rotatably connected to the first rotating rod 7, and the first rotating rod 7 is rotatably connected to the bearing column 8. This facilitates the effective transmission and dispersion of external forces when the hinge is subjected to external forces through the synergistic action of the first support frame 3, the first rotating rod 7, and the bearing column 8, thereby enhancing the overall stability and load-bearing capacity of the hinge structure.

[0034] A load column 9 is slidably connected to the lower end of the load column 8, and a first return spring 10 is fixedly connected to the inner bottom surface of the load column 9. The upper end face of the first return spring 10 is fixedly connected to the lower end face of the load column 9, which allows the load column 9 to slide along the load column 8 when the load changes. Through the elastic action of the first return spring 10, the impact force generated by the load is effectively buffered and absorbed, thereby protecting the hinge structure from damage. At the same time, this design can also ensure that the hinge remains stable when subjected to heavy loads and extend its service life.

[0035] A baffle 11 is fixedly connected to the outer end face of the upper side of the load column 9, and the baffle 11 is symmetrically arranged about the center of the load column 8. A second return spring 14 is fixedly connected to the inner top surface of the baffle 11, which allows the baffle 11 to limit the displacement range of the load column 9 during the rising or falling process, preventing it from moving excessively and detaching from the load column 8. At the same time, the setting of the second return spring 14 can further enhance the buffering effect. When the load column 9 is subjected to external force, the second return spring 14 can undergo elastic deformation to absorb and disperse the impact force, further protecting the safety and stability of the hinge structure. This design not only improves the load-bearing capacity of the hinge, but also enhances its ability to adapt to complex load environments.

[0036] The end of the load column 9 is rotatably connected to the second rotating rod 12, and the second rotating rod 12 is rotatably connected to the first auxiliary bracket 4; the first hinge base 1 and the second hinge base 2 are both fixedly connected to the movable plate 13 by the stud assembly, which facilitates the enhancement of the overall rigidity and stability of the hinge structure, enabling it to better withstand the challenges of heavy load and complex load environment.

[0037] Working principle: When the hinge structure is subjected to external force, hinge base 1 and hinge base 2 serve as the main support points. Through the coordinated rotation of support frame 3, auxiliary support 4, auxiliary support 5, and support frame 6, the impact force can be effectively dispersed and absorbed. The rotational connection between auxiliary support 4 and auxiliary support 5 allows the hinge to adjust its posture more flexibly when subjected to lateral force, reducing stress concentration and preventing deformation or breakage. This further enhances the hinge's resistance to deformation, enabling it to maintain a stable structural shape when subjected to forces in various directions.

[0038] The rotational connection between the first rotating rod 7 on the first support frame 3 and the bearing column 8 is an important force transmission and dispersion point in the hinge structure. When an external force is applied to the hinge, the first support frame 3, the first rotating rod 7, and the bearing column 8 work together to effectively transmit the external force to the load column 9. The impact force is buffered and absorbed through the sliding of the load column 9 on the bearing column 8 and the elastic action of the first return spring 10. This design not only improves the load-bearing capacity of the hinge, but also makes it more stable and reliable when facing complex load environments.
