The positioning component includes an elastic member arranged on the hinge base and a positioning member connected to the elastic member. The positioning member contacts the movable hinge so that a static friction can be formed between the positioning member and the movable hinge. The hinge structure of the embodiment of the present application has high safety.
[0004] However, in the actual use process of the existing hinge, when opening and closing the cabinet door of the freezer, it is difficult to master the force applied by the personnel during the opening and closing process. As a result, when the opening and closing force is relatively large, it is easy to cause a large impact between the freezer and the cabinet door. In the long run, not only the connection of the hinge is likely to become loose, but also the freezer is likely to be damaged, and the protection effect is poor. Moreover, the strength of the general hinge is average. When the object linked to the freezer is relatively heavy, its bearing capacity is limited, which affects the use of the freezer. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a high-strength load-bearing hinge for a freezer. By constructing a buffer component inside the hinge, when the freezer is opened and closed to drive the hinge to move, the buffer component inside the hinge can effectively slow down the force applied by the personnel and reduce the inertia generated during the opening and closing process of the freezer, so that the opening and closing of the freezer can have a certain retardation, avoiding impact damage to the freezer caused by a large opening and closing force, and the overall strength of the hinge can be improved under the action of the strengthening component, thereby improving the service life.

Detailed implementation mode
[0030] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.
[0031] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.
[0032] In the description of this patent, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this patent.
[0033] In the description of this patent, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "setting" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.
[0034] Refer to Figures 1-4, A high-strength load-bearing hinge for a freezer, comprising: a lower base 1 and an upper base 2, which are connected and installed through a first connecting shaft 3, and the upper base 2 is located inside the lower base 1. This structural design enhances the overall stability and load-bearing capacity of the hinge. This design enables the hinge to maintain a stable connection when bearing the weight of the freezer door body and the internal items, reducing the risk of loosening and deformation; a guide groove 15, which is opened on both sides of the surface of the lower base 1, and a buffer assembly is constructed inside the guide groove 15. When the freezer door body is opened and closed, the guiding portion 10 slides in the guide groove, and at the same time, the buffer assembly can effectively slow down the force applied by the person and reduce the inertia generated during the opening and closing process. This not only makes the opening and closing actions smoother but also avoids impact damage to the freezer caused by excessive opening and closing force; a guiding portion 10, which is connected through and extends into the guide groove 15 inside the upper base 2; a strengthening assembly, which is respectively installed inside the upper base 2 and the lower base 1. These assemblies are usually made of high-strength materials and are used to enhance the strength and durability of the hinge. They can resist wear and fatigue damage during long-term use, thereby extending the service life of the hinge; a reset assembly, which is installed inside the lower base 1 and connected to the guiding portion 10. When the freezer door body is closed, the reset assembly can ensure that the door body accurately and smoothly returns to the closed position and maintains a certain tightness.
[0035] Specifically, referring to Figure 1 - and Figure 4 , the buffer assembly includes: a second elastic member 17 and a ball 16; the second elastic members 17 are all installed inside the guide groove 15 and are in contact with the guiding portion 10, and the balls 16 are all installed inside the guide groove 15. Through this implementation method, during the relative flipping process of the upper and lower bases, the guiding portion 10 will move in the guide groove 15 around the first connecting shaft 3, and will come into contact with the second elastic member 17 during the movement process, thereby being able to effectively slow down the force applied by the person and being able to reduce the inertia generated during the opening and closing of the freezer. The buffer assembly can absorb and disperse these inertial forces, thereby reducing the impact damage to the freezer, and the guiding portion 10 can slide under the action of the balls 16, reducing the noise generated when the hinge moves.
[0036] Specifically, referring to Figures 1-3, the reset component includes: a traction part 11, a base 7, a limiting part 14, a second connecting shaft 8, and a first elastic part 12; the base 7 is installed inside the lower base 1 through the second connecting shaft 8, one end of the traction part 11 is hooked on the surface of the guiding part 10 and the other end penetrates into the base 7, the limiting part 14 is installed at the end of the traction part 11 that penetrates into the base 7, and the first elastic part 12 is connected between the base 7 and the traction part 11. Through this implementation, when the hinge moves, the directional flipping of the guiding part 10 can pull the traction part 11 to move, and the traction part 11 can stretch the first elastic part 12. Then, the other end of the traction part 11 can be prevented from detaching from the base 7 under the action of the limiting part 14. Since the hinge movement will cause the traction part 11 to have a certain angular flip, at this time, the base 7 can rotate under the action of the second connecting shaft 8 to prevent the traction part 11 from being difficult to move.
[0037] Furthermore, the first elastic part 12 is located outside the traction part 11. Through this design, the first elastic part 12 can move together with the traction part 11 better, so as to facilitate the subsequent reset of the hinge when it is closed, improve flexibility, and can also effectively utilize the limited space.
[0038] Specifically, referring to Figures 1-2 , the strengthening component includes: a reinforcing rib 4 and a reinforcing rod 9; the reinforcing rib 4 is fixed inside the upper base 2, the reinforcing rod 9 is connected inside the lower base 1 and penetrates through the traction part 11, and a through hole 13 with a diameter larger than that of the reinforcing rod 9 is formed on the surface of the traction part 11. Through this implementation, the reinforcing rib 4 provides support and stability inside the upper base 2, increasing the rigidity and load-bearing capacity of the upper base 2 to improve the overall strength of the upper base 2. The reinforcing rod 9 provides stable support inside the lower base 1, enhancing the structural strength of the entire hinge by adding additional support points. This design makes the hinge more stable when bearing the weight of the door body and external impacts, reducing the risk of failures caused by structural looseness or deformation. The structure of the strengthening component significantly improves the load-bearing capacity of the high-strength load-bearing hinge of the freezer.
[0039] Furthermore, the reinforcing ribs 4 are arranged in a cross shape, and the reinforcing rods 9 penetrate through the through holes 13. Through this design, it has excellent stability and strength in mechanics and can effectively resist stresses and impact forces from all directions. Therefore, during the opening and closing processes of the freezer door body, the hinge structure can remain more stable, reducing problems such as looseness or deformation caused by long-term use. The cross-arranged reinforcing rods make the force transmission inside the hinge more uniform. When the freezer door body is loaded with heavy objects, these reinforcing rods can share the weight together, thereby improving the overall load-bearing capacity of the hinge.
[0040] Furthermore, upper mounting holes 5 are provided on the surface of the upper base 2, and a lower mounting portion 6 is configured on the surface of the lower base 1. With this design, the upper mounting holes 5 enable the upper base 2 to be conveniently fixed to the corresponding position of the freezer cabinet. During the installation process, fasteners such as bolts and screws can pass through the upper mounting holes to fasten the upper base 2 to the cabinet, thus achieving a stable installation of the hinge. The configuration of the lower mounting portion 6 allows for a closer connection between the lower base 1 and the freezer cabinet. The lower mounting portion may include various forms of protrusions, grooves, or mounting interfaces to ensure that the lower base 1 can be accurately installed at the designated position on the cabinet and provide stable support.
[0041] Working principle: When using the present utility model, first, the hinge is connected and installed to the freezer through the upper and lower bases, enabling the upper base 2 to be fixed under the action of the upper mounting holes 5, and the lower base 1 to be fixed under the action of the lower mounting portion 6. Then, when the freezer is opened and closed, since a buffer assembly is configured inside the shackle, during the relative flipping of the upper and lower bases, the guiding portion 10 will move within the guiding groove 15 around the first connecting shaft 3, and will come into contact with the second elastic member 17 during the movement, thereby effectively slowing down the force applied by the person and reducing the inertia generated during the opening and closing of the freezer. The buffer assembly can absorb and disperse these inertial forces, thus reducing the impact damage to the freezer, protecting the integrity and stability of its structure, enabling the opening and closing of the freezer to have a certain retardation, avoiding impact damage to the freezer caused by a large opening and closing force, and enabling the guiding portion 10 to slide more smoothly under the action of the balls 16. The reinforcing ribs 4 and the reinforcing rods 9 inside the hinge are made of high-strength materials, such as high-quality steel, alloy, or special composite materials. These materials have excellent mechanical properties and load-bearing capacity. Therefore, when the reinforcing assembly is integrated into the hinge, it can significantly improve the overall load-bearing capacity of the hinge, enabling it to bear the weight of a heavier door body and the internal items, thus ensuring the stability and safety of the freezer during long-term use, improving the overall strength of the hinge, and thereby increasing the service life.
[0042] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
