Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and more particularly to a detachable hinge. Background Technology
[0002] A hinge, also known as a hinge leaf, is a type of component that typically consists of two folds, used to connect two parts of an object and allow them to move. It is commonly used in cabinet doors, windows, and other similar structures. Materials include iron, copper, and stainless steel. However, ordinary hinges do not have the function of spring hinges; after installation, various catch plates must be installed, otherwise the wind will blow the door panel open. With the development of modern life, swivel hinges have also become an important choice for both daily life and work.
[0003] A search revealed Chinese patent publication number CN115977486B, which discloses a frame hinge assembly and a door hinge assembly. The frame hinge assembly includes: a mounting frame for detachable connection to the door frame; and a hinge base fixedly installed within a receiving cavity of the mounting frame. The door hinge assembly includes: a fixing plate for detachable connection to the door leaf; a hinge cantilever for connecting the fixing plate and the pivot sleeve, the hinge cantilever being able to rotate and close the door hinge assembly and extend into the receiving cavity of the mounting frame; a pivot sleeve hinged to the hinge base via a hinge pivot; and an elastic support for elastically supporting the pivot sleeve. This concealed hinge of the present invention has a simple structure, greatly simplifying the hinge's transmission structure, reducing the number of parts, and minimizing the space occupied by the hinge's transmission structure. It also improves the overall load-bearing capacity of the hinge, making it suitable for heavy doors and doors with thinner panels, thus extending its service life.
[0004] The aforementioned patent has the following shortcomings: However, the hinges currently available on the market are not very convenient to use and cannot provide a detachable effect.
[0005] Therefore, we offer detachable hinges. Utility Model Content
[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a detachable hinge, thus achieving a detachable design.
[0007] In view of this, the present invention provides a detachable pivot hinge, including a solid pivot column, a lower hinge piece fixedly connected to the outer wall of the solid pivot column, a pivot column fixedly connected to the top of the solid pivot column, a small bearing fixedly connected to the top of the pivot column, a connecting column fixedly connected inside the small bearing, an outer pivot plate fixedly connected to the top of the connecting column, and an inner connecting plate fixedly connected to the bottom of the connecting column.
[0008] A fixed box block is fixedly connected to one side of the inner plate. An inner spring is fixedly connected inside the fixed box block. A movable block is fixedly connected to one end of the inner spring. A hollow rotating column is movably connected to the top of the solid rotating column. An upper closing piece is fixedly connected to the outer wall of the hollow rotating column. This facilitates the carrying of the rotating hinge and makes it easy to replace the rotating hinge when different parts are damaged. It reduces the overall cost of using the rotating hinge and is conducive to the long-term use of the rotating hinge.
[0009] Preferably, one side of the upper hinge is movably connected with four mounting bolts, which facilitates the overall fixing of the hinge and provides stability for subsequent hinge operations.
[0010] Preferably, a lower rubber pad is fixedly connected to one side of the lower hinge piece, and an upper rubber pad is fixedly connected to one side of the upper hinge piece. The upper and lower rubber pads can protect the hinge blades and their external contact surfaces, provide buffering for the two original contact surfaces, avoid damage to the external contact surfaces caused by pressure from hard objects, improve the reliability of the hinge during use, and reduce damage to external components.
[0011] Preferably, the outer wall of the pivot column is movably connected to a rolling pivot column, and the height of the rolling pivot column is equal to the height of the hollow pivot column. When the hinge rotates, the rolling pivot column will also rotate, thereby reducing the friction when the hinge rotates and improving the overall service life of the hinge.
[0012] Preferably, the bottom of the outer rotating plate is fixedly connected to the top of the connecting column, and the length of the outer rotating plate is less than the diameter of the rotating column, which facilitates the rotation of other components connected to the connecting column.
[0013] Preferably, the top of the inner plate is fixedly connected to the bottom of the connecting column, and the length of the inner plate is equal to the internal diameter of the rotating column, which facilitates the internal connection of other components to the rotating column.
[0014] Preferably, the movable block is movably connected to the interior of the fixed box block via an inner spring, and each fixed box block is provided with two inner springs, which facilitates the position adjustment of the movable block, thereby making the hinge stable during assembly and quick to disassemble.
[0015] Compared with the prior art, the present invention provides a detachable hinge, which has the following advantages:
[0016] This invention, through the design of a solid rotating column, a lower hinge plate, a rotating shaft column, a small bearing, an outer rotating plate, an inner connecting plate, a fixed box block, an inner spring, a movable block, a connecting column, a hollow rotating column, and an upper hinge plate, allows the hinge to be used when the hollow rotating column is fitted onto the outer wall of the rotating shaft column. Rotating the outer rotating plate causes the connecting column to rotate the inner wall of the small bearing and the inner connecting plate, thus positioning the movable block at the opening on the outer wall of the rotating shaft column. The elastic potential energy of the inner spring pushes the movable block out of the fixed box block and the interior of the rotating shaft column, placing it above the hollow rotating column. For disassembly, the movable block is pressed into the interior of the rotating shaft column, and the outer rotating plate is simultaneously rotated to prevent the movable block from popping out from the inner wall of the rotating shaft column. This allows the solid and hollow rotating columns to separate, completing the disassembly of the rotating shaft hinge. This facilitates the carrying and replacement of the hinge when different components are damaged, reducing the overall cost of using the hinge and promoting its long-term use. This invention, through the installation bolts, upper rubber pad, lower rubber pad, and rolling pivot, allows the hollow pivot to be fitted onto the pivot post while the rolling pivot is placed in the gap between the hollow pivot and the pivot post. As the hinge rotates, the rolling pivot also rotates, reducing friction and extending the overall service life of the hinge. When the hinge pieces are fixed with the installation bolts, the upper and lower rubber pads protect the hinge blades and their external connecting surfaces, providing cushioning for the two original contact surfaces and preventing damage caused by hard objects pressing on the external connecting surfaces. This improves the reliability of the pivot hinge during use and reduces damage to external components.
[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Example 1: As Figures 1-5As shown, the detachable hinge includes a solid pivot 1, a lower hinge piece 2 fixedly connected to the outer wall of the solid pivot 1, a pivot 3 fixedly connected to the top of the solid pivot 1, a small bearing 4 fixedly connected to the top of the pivot 3, a connecting column 10 fixedly connected inside the small bearing 4, an outer pivot plate 5 fixedly connected to the top of the connecting column 10, an inner connecting plate 6 fixedly connected to the bottom of the connecting column 10, a fixing box block 7 fixedly connected to one side of the inner connecting plate 6, an inner spring 8 fixedly connected inside the fixing box block 7, a movable block 9 fixedly connected to one end of the inner spring 8, a hollow pivot 11 movably connected to the top of the solid pivot 1, and an upper hinge piece 12 fixedly connected to the outer wall of the hollow pivot 11. This design facilitates the carrying of the hinge and makes it easy to replace different parts when they are damaged, reducing the overall cost of using the hinge and promoting its long-term use. The upper hinge 12 has four mounting bolts 13 movably connected to one side, which facilitates the overall fixing of the hinge and provides stability for subsequent operation. The lower hinge 2 has a lower rubber pad 15 fixedly connected to one side, and the upper hinge 12 has an upper rubber pad 14 fixedly connected to one side. The upper rubber pad 14 and the lower rubber pad 15 can protect the hinge blades and their external contact surfaces, providing a buffer for the two original contact surfaces and preventing damage caused by hard objects pressing on the external contact surfaces. This improves the reliability of the hinge during use and reduces damage to external components. The outer wall of the pivot column 3 is movably connected to a rolling pivot 16, and the height of the rolling pivot 16 is equal to the height of the hollow pivot 11. When the hinge rotates, the rolling pivot 16 also rotates, thereby reducing friction during hinge rotation and improving the overall service life of the hinge.
[0027] First, the hollow rotating column 11 is fitted onto the outer wall of the rotating shaft column 3. The rolling rotating column 16 is then placed into the gap between the hollow rotating column 11 and the rotating shaft column 3. At this point, rotating the outer rotating plate 5 causes the connecting column 10 to rotate the inner wall of the small bearing 4 and the inner connecting plate 6, thereby positioning the movable block 9 at the opening on the outer wall of the rotating shaft column 3. The elastic potential energy of the inner spring 8 pushes the movable block 9 out of the fixed box block 7 and the interior of the rotating shaft column 3, positioning the movable block 9 above the hollow rotating column 11. Finally, the upper mating plate 12 and the lower mating plate 2 are installed using the mounting bolts 13. For installation, if disassembly is required, rotate the mounting bolt 13 and remove the entire hinge. Press the movable block 9 into the interior of the pivot column 3, and simultaneously rotate the outer rotating plate 5. This prevents the movable block 9 from popping out from the inner wall of the pivot column 3, allowing the solid pivot column 1 and the hollow pivot column 11 to separate, thus completing the disassembly of the pivot hinge. This facilitates the carrying of the pivot hinge and makes it easy to replace different parts when they are damaged, reducing the overall cost of using the pivot hinge and promoting its long-term use.
[0028] Example 2: Figures 1-5As shown, the detachable pivot hinge has the bottom of the outer pivot plate 5 fixedly connected to the top of the connecting post 10, and the length of the outer pivot plate 5 is less than the diameter of the pivot post 3, which facilitates the rotation of other components connected to the connecting post 10. The top of the inner connecting plate 6 is fixedly connected to the bottom of the connecting post 10, and the length of the inner connecting plate 6 is equal to the internal diameter of the pivot post 3, which facilitates the internal connection of other components to the pivot post 3. The movable block 9 is movably connected to the inside of the fixed box block 7 through the inner spring 8, and each fixed box block 7 is provided with two inner springs 8, which facilitates the position adjustment of the movable block 9, thereby making the hinge stable when assembled and quick to disassemble.
[0029] First, when fixing the upper hinge 12 and the lower hinge 2, the upper rubber pad 14 and the lower rubber pad 15 are in contact with the wall. When the mounting bolt 13 is turned and tightened, the upper rubber pad 14 and the lower rubber pad 15 can provide buffer for the connection surface, reduce damage between the connection surfaces, and improve the overall service life of the hinge.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
