Description

Technical Field

[0001] The present invention relates to the technical field of hinges, and in particular to a hinge mechanism. Background Art

[0002] A hinge is a device used to connect or rotate, so that a door, cover or other swinging parts can be rotated to open or close, usually consisting of a pair of metal leaf sleeves connected by a pin.

[0003] Hinges are the most important components of swing doors, responsible for bearing the entire load and ensuring smooth opening of the door leaf. However, heavy-duty hinges currently available on the market suffer from complex and unreliable structures, making them difficult to install and having a short lifespan. These problems become increasingly severe as the weight and specifications of the door leaf increase. Not only is installation cumbersome, but it also affects proper closing and even risks hinge damage and the door leaf falling. Therefore, a hinge mechanism is provided to address these issues. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a hinge mechanism to solve the problem that the existing hinge mechanism has insufficient load-bearing and wear resistance.

[0005] A hinge mechanism of the present invention can be realized by the following technical solutions:

[0006] A hinge mechanism of the present invention includes a main shaft assembly; a first hinge assembly fixedly connected to the main shaft assembly; a second hinge assembly rotatably disposed on the main shaft assembly; and two mounting cap assemblies, each of which is fixedly disposed on the first hinge assembly and the second hinge assembly, respectively.

[0007] In which, the main shaft assembly includes a shaft body, one end of which is fixedly arranged in the first hinge assembly, and the second hinge assembly is rotatably arranged on the shaft body; a plane bearing mechanism that rotates through the shaft body and is close to the first hinge assembly, and is in contact and connected with the second hinge assembly; a first rotating body that rotates through the shaft body and is away from the first hinge assembly, and the inner wall of the second hinge assembly is in contact and connected with at least one of the first rotating bodies; and a second rotating body that is movably arranged on the side of the shaft body close to the plane bearing mechanism.

[0008] In one embodiment, a guide head is provided on one end of the shaft body opposite to the first hinge assembly, and a plurality of longitudinal grooves are provided on the guide head.

[0009] In one embodiment, the shaft body includes a first connecting part, which is fixedly connected to the first hinge assembly; a second connecting part fixedly arranged on one side of the first connecting part, which is integrally formed with the first connecting part, and the second hinge assembly is rotatably arranged on the second connecting part, and a plurality of steps are provided on the second connecting part, and the plane bearing mechanism, the second rotating body, at least one of the first rotating bodies, and the guide head are arranged on the second connecting part in sequence from bottom to top.

[0010] In one embodiment, the plane bearing mechanism includes a plane bearing body that is rotatably disposed on the shaft body; a first gasket and a second gasket that are respectively disposed on the shaft body and on opposite sides of the plane bearing body.

[0011] In one embodiment, the plane bearing body is a needle roller plane bearing; the first rotating body is a roller bearing; and the second rotating body is a roller bearing or a copper sleeve.

[0012] In one embodiment, the first hinge assembly includes a first connecting sleeve, which is fixedly mounted on the shaft body; a first hinge body fixedly mounted on a side of the first connecting sleeve, and a plurality of first fixing holes are formed through the first hinge body.

[0013] In one embodiment, the second hinge assembly includes a second connecting sleeve, which is rotatably mounted on the shaft body and is in contact with the plane bearing mechanism, and at least one of the first rotating bodies is in contact with the inner wall of the second connecting sleeve; a second hinge body fixedly connected to the second connecting sleeve, and a plurality of second fixing holes are provided on the second hinge body; and a ball screw that passes through the second connecting sleeve and is capable of being in contact with the shaft body.

[0014] In one embodiment, a connecting hole is provided through the second connecting sleeve, an internal thread is provided in the connecting hole, and the ball screw is adjustable through the connecting hole to pass through the second connecting sleeve and contact and connect with the shaft body.

[0015] In one embodiment, the mounting cap assembly includes a mounting cap body, which is fixedly sealed and disposed on the first connecting sleeve or the second connecting sleeve; and a sealing screw that is detachably threaded and connected to the mounting cap body.

[0016] In one embodiment, an oil filling hole is provided through the mounting cap body, an internal thread is provided inside the oil filling hole, and the sealing screw is detachably threadedly connected to the oil filling hole.

[0017] Compared with the prior art, the hinge mechanism of the present invention has the following beneficial effects:
