[0001] The utility model relates to the technical field of hinges, in particular to a biaxial damping rotating shaft hinge. Background Technique

[0002] A biaxial hinge is a hinge with a unique design, usually used to connect two planes and allow them to rotate around two different axes. Compared with traditional single-axis hinges, biaxial hinges can provide more degrees of freedom and flexibility, enabling the connected objects to perform complex movements in different directions;

[0003] When existing cabinet doors or doors and windows are quickly and suddenly opened and closed, the biaxial hinges connected to them do not have the functions of damping and buffering, resulting in collisions and damages between the cabinet doors and doors and windows and other items, causing property losses. For this reason, we propose a biaxial damping rotating shaft hinge. Content of the Utility Model

[0024] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0025] In the description of the present utility model, unless otherwise specified, "a plurality of" means two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model 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 cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] As Figures 1-7 shown, the present utility model provides a technical solution: a double-axis damping rotating shaft hinge, including a first hinge seat 1, a hinge plate 2 and a second hinge seat 3, and a damping hinge mechanism 4 is provided between the two ends of the hinge plate 2 and the first hinge seat 1 and the second hinge seat 3 respectively;

[0028] The damping hinge mechanism 4 includes a magnetic block 401, a rotating cylinder 404 and a hinge shaft 406. The magnetic block 401 is fixedly installed on the outer wall of one end of the hinge plate 2. A first magnetic plate 402 and a second magnetic plate 403 are respectively fixedly installed on the front and back of the outer wall of the hinge plate 2 near one end. The hinge plate 2 near one end is movably sleeved on the outer wall of the rotating cylinder 404 through a cylindrical hole opened. The rotating cylinder 404 is limited and slides with the inner wall of the cylindrical hole. The rotating cylinder 404 is movably sleeved on the hinge shaft 406. A torsion spring 405 is fixedly connected between the inner wall of the rotating cylinder 404 and the outer wall of the hinge shaft 406. Fixed frames 5 are fixedly installed at both the top and bottom of the first hinge seat 1. A screw rod 7 is threadedly connected to a threaded hole opened on the fixed frame 5. A pin column 9 is fixedly installed at the bottom of the screw rod 7. Pin slots 6 are opened at both ends of the hinge shaft 406. The pin column 9 movably passes through the first hinge seat 1 and is inserted into the pin slots 6. A rotating plate 8 is fixedly installed at the top of the screw rod 7.

[0029] Specifically, in the above technical solution, the hinge plate 2 rotates on the first hinge seat 1 or the second hinge seat 3 rotates on the hinge plate 2. And when rotating to a certain angle, the magnetic block 401 will contact the first magnetic plate 402 or the second magnetic plate 403, making the magnetic block 401 and the first magnetic plate 402 or the second magnetic plate 403 magnetically attract each other, playing a good damping role. After the hinge plate 2 drives the limit sliding groove 408 to rotate a certain angle, the hinge plate 2 will drive the rotating cylinder 404 to rotate through the slider 407, making the rotating cylinder 404 drive the torsion spring 405 to twist, storing the external force received by the hinge to play a good buffering role. At the same time, when the external force disappears, through the action of the torsion spring 405, the hinge can be driven to return to its original state, and during the recovery, the magnetic block 401 and the first magnetic plate 402 or the second magnetic plate 403 are used to decelerate; through this mechanism, the double-axis hinge can generate a certain damping force when rotating to a certain angle during use, and can buffer the kinetic energy, making it more stable when opening and closing cabinets, doors and windows, etc., avoiding hitting items and causing collisions, solving the problem that the existing cabinets, doors and windows, etc. do not have the functions of damping and buffering during rapid and sudden opening and closing movements, resulting in collisions and damages between the cabinets, doors and windows, etc. and other items, causing property losses; when it is necessary to disassemble and maintain the double-axis hinge, the rotating plate 8 can be rotated. The rotating plate 8 drives the screw rod 7 to rotate. When the screw rod 7 rotates, it moves upward. The screw rod 7 drives the pin column 9 to move upward, making the pin column 9 disengage from the pin slot 6, so that the pin column 9 no longer limits the hinge shaft 406. At this time, the hinge plate 2 can be disengaged from the first hinge seat 1 or the second hinge seat 3 to complete the disassembly. Through the above structure, it is convenient for personnel to disassemble the double-axis hinge, so as to facilitate personnel to maintain it and ensure the normal use effect of the hinge. The structure is simple and the practicability is strong.

[0030] Further, the shapes of the pin column 9 and the pin slot 6 are both rectangular, and the pin column 9 and the pin slot 6 are adapted to each other;

[0031] Among them, by setting the pin post 9, the pin post 9 can be inserted into the pin slot 6, thereby limiting the hinge shaft 406.

[0032] Furthermore, the number of the magnets 401, the first magnetic plates 402 and the second magnetic plates 403 on the first hinge seat 1 is two, and the opposite surfaces of the magnets 401 and the first magnetic plates 402, the second magnetic plates 403 are magnetically opposite;

[0033] Among them, by setting the magnets 401, the first magnetic plates 402 and the second magnetic plates 403, a damping effect can be exerted on the hinge plate 2 during rotation.

[0034] Furthermore, a slider 407 is fixedly installed on the outer wall of the rotating cylinder 404, and a limiting sliding groove 408 is formed in the inner wall of the cylinder hole opened near one end of the hinge plate 2, and the slider 407 is slidably connected with the limiting sliding groove 408;

[0035] Among them, by setting the slider 407, the hinge plate 2 can drive the rotating cylinder 404 to rotate through the slider 407.

[0036] Furthermore, the number of the sliders 407 on the rotating cylinder 404 is two, and the sliders 407 are adapted to the limiting sliding grooves 408.

[0037] Furthermore, the limiting sliding groove 408 is an arc-shaped groove, and the center of the arc-shaped groove is on the central axis of the hinge shaft 406.

[0038] The embodiments of the present invention are given for the purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
