Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and particularly relates to a hinge mechanism with a limiting and adjustable rotation tightness function. Background Art

[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them, and it is mainly installed on doors and windows. The installation blades of ordinary door and window hinges are connected to the pin sleeve along the tangent direction of the pin sleeve. The surface where the installation blade is tangent to the pin sleeve is the installation surface. Only when the installation surfaces of the two installation blades are firmly installed on the door and window and the door and window frame respectively can the hinge play a reliable hinge role. In the prior art, the rotation angle of the rotating part relative to the fixed part in the hinge mechanism is generally relatively large. In some usage scenarios, it is not necessary for the door and window connected to the rotating part to be fully opened relative to the door and window frame. In this case, other components are required to perform a limiting operation on the door and window, making the limiting operation of the door and window relatively cumbersome, thereby reducing the user experience. At the same time, in the prior art, the main shaft in the hinge mechanism is generally fixedly arranged on the fixed part during production and assembly, and the position of the main shaft relative to the fixed part cannot be adjusted, so that the rotation tightness between the rotating part and the main shaft cannot be adjusted according to actual installation requirements. Therefore, a hinge mechanism with a limiting and adjustable rotation tightness function is provided to solve the above problems. Content of the Utility Model

[0003] One of the purposes of the utility model is to provide a hinge mechanism with a limiting and adjustable rotation tightness function, so as to solve the problems that the existing hinge mechanism does not have a limiting function and cannot adjust the rotation tightness.

[0004] A hinge mechanism with a limiting and adjustable rotation tightness function of the utility model can be realized by the following technical solutions:

[0005] A hinge mechanism with a limiting and adjustable rotation tightness function of the utility model includes two fixed parts, which are arranged opposite to each other; a main shaft assembly, which is adjustably arranged between the two fixed parts; a limiting rod, which is detachably and fixedly arranged between the two fixed parts and is arranged on the side of the main shaft assembly; a rotating part, which is rotatably arranged on the main shaft assembly, and the limiting rod performs a limiting operation on the rotation angle of the rotating part.

[0006] Among them, the main shaft assembly includes a main shaft body, which respectively penetrates through the two fixed parts and is detachably threadedly connected to one of the fixed parts; two plain bearings respectively penetrating through the main shaft body, and the rotating part is arranged between the two plain bearings; a fastening nut detachably threadedly connected to the main shaft body and in contact connection with the corresponding fixed part.

[0007] In one embodiment, the fixing member includes a first fixing plate vertically and fixedly mounted on the door and window frame; a mounting plate horizontally disposed on the first fixing plate, and one ends of the main shaft assembly and the limiting rod are respectively fixedly disposed on the mounting plate.

[0008] In one embodiment, the mounting plate is integrally formed on the first fixing plate by a punching, shearing and bending process.

[0009] In one embodiment, through holes and mounting holes are respectively formed through the mounting plate; both ends of the main shaft assembly respectively penetrate through the corresponding through holes; both ends of the limiting rod are respectively detachably and fixedly disposed in the corresponding mounting holes.

[0010] In one embodiment, the main shaft body includes a screwing head, a connecting rod and a threaded rod arranged in sequence; the threaded rod is synchronously and detachably threadedly connected to the corresponding mounting plate and the fastening nut.

[0011] In one embodiment, the screwing head is a flat-blade screwing head, a cross-blade screwing head or a hexagonal screwing head.

[0012] In one embodiment, gaskets are arranged at the parts where the plain bearings are respectively in contact with the mounting plate and the rotating member.

[0013] In one embodiment, the rotating member includes a second fixing plate vertically and fixedly mounted on the door and window; a rotating plate arranged on the side of the second fixing plate and rotatably arranged on the main shaft, which is arranged between the two plain bearings, and the rotating plate is integrally formed on the side of the second fixing plate by a punching, shearing and bending process.

[0014] In one embodiment, a rotating hole is formed in the side of the rotating plate, which movably penetrates through the main shaft and is arranged between the two plain bearings.

[0015] In one embodiment, shaft sleeves are respectively arranged at both ends of the rotating hole.

[0016] Compared with the prior art, the beneficial effects of the hinge mechanism with a limiting and adjustable rotation tightness function of the present utility model are as follows:

[0017] The hinge mechanism of the present utility model with a limit and adjustable rotation tightness function detachably and fixedly arranges a limit rod between two fixing parts, and the rotation angle of the rotating part is limited by the limit rod, effectively solving the problem that the existing hinge mechanism does not have a limit function. When the limit function of the hinge mechanism is not required, the limit rod can be detached from the two fixing parts; at the same time, the fixing parts and the rotating part are integrally formed by a punching, shearing and bending process, making the hinge mechanism have the characteristics of simple processing and low cost;

[0018] The hinge mechanism of the present utility model with a limit and adjustable rotation tightness function makes the threaded rod synchronously and detachably thread - connected with the corresponding fixing part and fastening nut by rotating the screwing head, thereby adjusting the tightness between the main shaft body and the rotating part, effectively solving the problem that the existing hinge mechanism cannot adjust the rotation tightness; at the same time, through the tight connection between the fastening nut and the main shaft body, it effectively prevents the main shaft body from sliding or falling between the two fixing parts, enhancing the safety performance of the hinge mechanism to a certain extent.
