Description

  The present invention relates to a rotating shaft device capable of adjusting a torsional force.

  Rotating shaft devices are widely used, and hinges using these rotating shaft devices are used in doors, doors, closets, etc., and even in electronic products, laptop computer lids and mobile phones A rotating shaft device is also used for the lid portion of the head.

  The effect of such a rotating shaft device is that it can be used not only for opening and closing but also for angle adjustment. Since the rotation shaft device used for this angle adjustment needs to have a localization function in addition to the rotation, it is important to change and adjust the torsional force in the design, especially for the connected object or the suspended object. When the weight is very large, the design of the rotating shaft device is extremely important because it is necessary to consider the load problem.

  For example, the large displays currently in use are several tens of inches in size and are very heavy. For this reason, when the rotating shaft device used is not appropriate, the rotating shaft device located below the connected object must support the weight of the main body. Labor is required. Further, when adjusting the depression angle, the labor of the main body is high, so that much labor is not required. This is a basic element that must be considered in designing the pivoting shaft device.

  As described above, when the rotation shaft device is used for angle adjustment, it is necessary to have a localization function in addition to rotation. Therefore, it is important to change and adjust the torsional force, particularly for the connected object or the suspended object. When the weight is very large, load issues need to be considered.

  The present invention has been made in view of these circumstances, and an object thereof is to provide a rotating shaft device capable of adjusting a torsional force.
