Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical connection components, specifically relating to a hinge structure. Background Technology

[0002] Hinges, as the core component enabling rotational connections between parts, are widely used in furniture, doors and windows, machinery, automotive parts, and many other fields. In practical applications, different equipment or components have significantly different requirements for hinge dimensions. For example, small furniture cabinet door hinges require compact connection dimensions, while large industrial equipment hatch hinges require a larger span to meet opening and closing needs.

[0003] Currently, most hinge structures on the market are designed with fixed sizes, meaning a single hinge can only accommodate one specific hinge size. When adjusting the hinge size or adapting to different component specifications, the entire hinge set must be replaced. This not only increases user costs but also requires maintaining an inventory of hinges in various sizes, making the process cumbersome and inflexible. Furthermore, some hinge structures lack stable isolation and positioning mechanisms between components during assembly, making them prone to loosening and misalignment, affecting the hinge's lifespan and connection stability. In addition, the disassembly and assembly process of traditional hinges is complex. When internal components need repair or replacement, it often requires significant time and manpower, hindering maintenance efficiency.

[0004] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0005] The main objective of this invention is to provide a hinge structure that overcomes the shortcomings of existing hinge structures, such as poor adaptability, unstable assembly, and inconvenient disassembly. This hinge structure, through a combination design of multiple hinges and multiple bushings, allows for flexible selection of different hinges for hinge connection according to actual needs, resulting in wide adaptability. At the same time, bushings are used to achieve stable isolation of each hinge, improving connection stability. Furthermore, the threaded connection between screws and hinge pins simplifies the disassembly and assembly process, facilitating later maintenance.

[0006] To achieve the above objectives, this utility model provides a hinge structure, including a first hinge, a second hinge, a third hinge, a fourth hinge, a first bushing, a second bushing, a third bushing, a hinge pin, and a screw, wherein: The first hinge, the second hinge, the third hinge, the fourth hinge, the first bushing, the second bushing, and the third bushing are all sleeved on the hinge pin, and the screw is fixedly installed on the first end of the hinge pin; One end of the first hinge abuts against the screw and the other end of the first hinge abuts against one side of the first bushing; one end of the second hinge abuts against the other side of the first bushing and the other end of the second hinge abuts against one side of the second bushing; one end of the third hinge abuts against the other side of the second bushing and the other end of the third hinge abuts against one side of the third bushing; one end of the fourth hinge abuts against the other end of the third bushing and the other end of the fourth hinge abuts against the second end of the hinge pin. The first hinge, the second hinge, the third hinge, and the fourth hinge are each provided with an integrally formed first connector, a second connector, and a bent portion. The bent portion is sleeved on the hinge pin. The first connector is located on one side of the bent portion, and the second connector is located on the other side of the bent portion.

[0007] As a further preferred embodiment of the above technical solution, both the first connector and the second connector are provided with fixing holes.

[0008] As a further preferred embodiment of the above technical solution, the screw is threadedly connected to the first end of the hinge pin.

[0009] As a further preferred technical solution to the above technical solution, each bushing has a chamfered structure on both sides.

[0010] As a further preferred embodiment of the above technical solution, the screw is a hexagonal screw.

[0011] The beneficial effects of this utility model are as follows: 1. Wide adaptability: This utility model features four independent hinges, each hinge being fitted onto a hinge pin via a curved portion and capable of rotating relative to the hinge pin. In use, any two hinges can be flexibly selected and combined according to the actual hinge size requirements. For example, when the hinge size requirement is small, the first and second hinges can be selected; when the hinge size requirement is large, the first and fourth hinges can be selected. There is no need to replace the entire set of hinges, effectively adapting to connection needs in different scenarios and reducing usage costs.

[0012] 2. Stable connection: The first bushing, second bushing, and third bushing isolate and position the first hinge with the second hinge, the second hinge with the third hinge, and the third hinge with the fourth hinge, respectively. This ensures that each hinge maintains a stable distance on the hinge pin, preventing loosening or displacement during use and significantly improving the overall connection stability and service life of the hinge structure.

[0013] 3. Easy disassembly and assembly: The screws and hinge pins are connected by threads. When it is necessary to inspect or replace the bushings or hinges, you only need to unscrew the screws to remove each part from the hinge pins without damaging the hinge structure. This greatly simplifies the disassembly and assembly process and saves maintenance time and labor costs. Attached Figure Description
