Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a novel hinge shaft core. Background Art

[0002] A hinge is a device used to connect objects and allow them to rotate or swing around. It usually consists of two parts, one part is fixed to one object, and the other part is fixed to another object and allows them to rotate relative to each other, such as the connection between a door and a door frame. Hinge is designed to provide a stable connection while allowing movement, and is commonly used for the connection and moving parts of objects such as doors, windows, and box lids. There are many different designs of hinges, including hinge hinges, ball hinges, friction hinges, etc. Their selection depends on the specific requirements of the application and the purpose of the design.

[0003] After searching, the patent number is CN208220469U, and the specific name is a hydraulic hinge core shaft and a hydraulic hinge having the same, wherein the hydraulic hinge core shaft includes a shell, a shaft core and a piston, and the outer surface of the shaft core near the piston is provided with a plurality of first planes sequentially connected along the circumferential direction of the shaft core, and the first plane is cut on the outer surface of the shaft core by being parallel to the axis of the shaft core, and a plurality of second planes are provided on the inner wall of the piston longitudinal through hole near the shaft core, and the plurality of second planes correspond to and match the plurality of first planes one by one, and after the end of the shaft core is inserted into the longitudinal through hole of the piston, each first plane matches with each corresponding second plane, so that the rotation of the shaft core can drive the rotation of the piston, so that the spiral groove slides relative to the piston fixing pin, and then the piston moves in the axial direction;

[0004] The hydraulic hinge in this patent can adjust the closing speed of the door when in use, but cannot control the closing angle of the door. In some specific application scenarios, it may be necessary to precisely control the closing angle of the door to ensure that the position of the door is completely matched with the surrounding structure or equipment. Therefore, the lack of control over the closing angle may cause the door position to be inaccurate and unable to meet specific needs. Utility Model Content
