Description

Technical Field

[0001] This utility model belongs to the technical field of cabinet hinge devices, specifically relating to hinge devices. Background Technology

[0002] Existing hinge mechanisms are primarily used to connect cabinet bodies and doors, allowing them to rotate relative to each other. They typically consist of a hinge cup and a hinge base that are interconnected. The hinge cup is fixed to the cabinet door with screws, while the hinge base is mounted to the cabinet body with screws. However, this traditional structure has significant drawbacks: when the cabinet door is damaged or requires deep cleaning, tools must be used to remove the entire hinge from the cabinet body, a cumbersome and inefficient process. The inability to quickly separate the hinge cup and hinge base complicates the maintenance or replacement of cabinet doors, impacting user experience. Furthermore, frequent screw removal and installation can cause thread wear, reducing the hinge's stability and lifespan, and lowering product reliability. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing hinge devices cannot be quickly disassembled and separated from the hinge cup and the hinge seat, and to provide a hinge device in which the hinge cup and the hinge seat can be quickly disassembled and separated.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The hinge mechanism includes an arm body, a hinge cup, a latching seat, a damper, a tail fastener, a hinge seat, and a rotating operating component. The arm body has a clearance cavity with a bottom opening. The hinge cup is connected to the articulated arm via a linkage assembly. The latching seat, placed within the clearance cavity, is slidably connected to the arm body via a guide structure and has a movable cavity with a front opening and first hooks located on both sides of the bottom front end. The damper is housed within the movable cavity, with its front side connected to the linkage assembly and its rear side rotatably connected to the two side walls of the clearance cavity via a first rotating shaft. The tail fastener is rotatably connected to the rear side of the latching seat via a second rotating shaft and has second hooks located on both sides of the bottom. A first torsion spring is sleeved on the second rotating shaft, with both ends of the first torsion spring abutting against the rear end of the arm body and the latching seat, respectively. Bottom; hinge seat, located at the bottom of the arm body, with a first hook hooked to the front end of the hinge seat and a second hook hooked to the rear end of the hinge seat; rotating operating component, rotatably connected to the second rotating shaft and assembled with the tail buckle through a plug-in structure, the rotating operating component has a rotating operating part located on the rear side and an abutment seat located on the inner side. By operating the rotating operating part, the tail buckle can be driven to flip upward relative to each other, and under the elastic drive of the first torsion spring, the second hook is disengaged from the rear end of the hinge seat, thereby realizing the detachable separation between the hinge cup and the hinge seat. Alternatively, when the first hook is hooked to the front end of the hinge seat, by operating the rotating operating part, the tail buckle can be driven to flip downward relative to each other, and under the elastic state of compressing the first torsion spring, the second hook hooks to the rear end of the hinge seat.

[0006] Compared with the prior art, the hinge device of this utility model has a hinge cup for connecting the cabinet door and a hinge seat for connecting the cabinet body. The fastening seat connecting the arm body is hooked to the front end of the hinge seat by a first hook, and a tail fastener is provided on the rear side of the fastening seat, which is hooked to the rear end of the hinge seat by a second hook. By operating the rotating operating component, the tail fastener can be driven to flip upward relative to the rear end of the hinge seat, so that the second hook can be disengaged from the rear end of the hinge seat, thereby realizing the disassembly and separation between the hinge cup and the hinge seat. Thus, the cabinet door can be quickly disassembled and separated from the cabinet body, which significantly improves the convenience of cabinet door maintenance, cleaning and replacement, and is easy to use.

[0007] Furthermore, the plug-in structure includes a plug-in interface disposed on the tail fastener and a plug-in part disposed inside the rotating operating member. The plug-in interface has openings on its upper side and front and rear sides. The front end of the plug-in part is provided with a limiting part extending to both sides. The plug-in part is inserted into the plug-in interface and abuts against the front side of the tail fastener through the limiting part. With this configuration, the plug-in structure is simple and the product assembly efficiency is high.

[0008] Furthermore, the tail fastener is made of metal, while the rotating operating component is made of plastic. This design, using plastic for the tail fastener, effectively reduces product manufacturing costs, and the plastic tail fastener also provides a good feel when handled.

[0009] Furthermore, the bottom of the rotating operating part is provided with an arc-shaped operating surface, and the arc-shaped operating surface is arranged with anti-slip texture; this design makes it convenient for users to operate the rotating operating part and provides good anti-slip effect.

[0010] Furthermore, the fastening seat and the hinge seat are connected by a positioning structure. The positioning structure includes positioning elements disposed on both sides of the bottom of the fastening seat and positioning grooves disposed on both sides of the hinge seat. The positioning elements are placed in the positioning grooves. With this arrangement, the connection between the fastening seat and the hinge seat is stable and the assembly reliability is high.

[0011] Furthermore, the guide structure includes a first screw and a first elliptical hole disposed on the arm body, and a second screw and a second elliptical hole disposed on the hinge seat. The first screw is slidably placed in the second elliptical hole, and the second screw is slidably placed in the first elliptical hole. With this configuration, the guide structure is simple to set, and the sliding connection between the hinge seat and the arm body is good.

[0012] Furthermore, the linkage assembly includes a first link, a second link, and a linkage member. The two ends of the first link are rotatably connected to the arm body and the hinge cup, respectively. The two ends of the second link are rotatably connected to the arm body and the hinge cup, respectively. The hinge cup, the first link, the arm body, and the second link constitute a four-bar linkage mechanism. The linkage member is rotatably connected to the damper and the second link, respectively. The hinge cup achieves relative extension or reset of the hinge device by linking the linkage assembly. With this configuration, the linkage assembly is simple to set up, and the linkage effect of the hinge device in relative opening and closing is good. Attached Figure Description
