The present invention relates to a hinge device for a monitor that supports a monitor and enables the monitor to rotate, and more particularly, a hinge shaft, a curling housing, a torque curling, and a torsion spring to the hinge shaft. Not only to make the rotation smooth, but also to form a rotating prevention piece bent on one side of the torque curling so that the monitor can be firmly stopped in the hinged state and easy installation of each configuration to improve the work efficiency It is possible to reduce the cost, as well as to form a wrinkle on one side of the disk spring to the torque generating force in the left / right rotation of the monitor by the hinge device of the monitor to smoothly rotate the left and right of the monitor.

In general, a computer monitor is a device that outputs a screen to the user to visually check the input value input from the hard of the computer main body. It is greatly reduced.

Therefore, in recent years, in order to make the most of the space occupied by the monitor, a thin liquid crystal monitor is mainly used. Such a liquid crystal monitor supports a load that connects the stand and the liquid crystal monitor to a stand mounted on the upper surface of the desk. The hinge device is combined to support the liquid crystal monitor from the upper surface of the desk and to rotate the liquid crystal monitor left / right or up / down.

The hinge device connecting the conventional LCD monitor to the stand has been developed and used in various ways. For example, a friction type hinge device that is simple to assemble and use has been proposed, which is fixed to the housing and the LCD monitor. The rotating shaft is configured to support the liquid crystal monitor and the torsion spring is prevented from being rotated by its own weight.

Such a hinge device has a remarkable decrease in the elasticity of the torsion spring due to the user repeatedly rotating the monitor up / down and left / right, thus failing to support the load of the liquid crystal monitor when used for a long time, thus losing the function of the hinge device. It is a frequent occurrence.

In addition, curling housings inside the hinge brackets and curling with bending pieces extended from one side in the inside of the curling housings are further interpolated to fix the position of the monitor which is variable by rotating the monitors up and down. The position of the variable monitor is fixed by the torque generated by the curling, but the latching piece of curling which generates the torque is formed to be biased only on one side of the curling, so that the holding force of the curling is not properly formed. There is a problem that the fixing force for fixing the variable monitor is gradually lowered so that the monitor frequently sags down in the variable position.

On the other hand, the hinge device of the conventional monitor has been devised in various ways, for example, the hinge device of the Utility Model Registration No. 310874 has been conceived.

This, as disclosed in the claims of the publication, the rotating shaft hole through which the rotating shaft penetrates, the rotating member hole into which the rotating member fixed to the liquid crystal monitor is inserted, and the housing fixing hole used for fixing the stand is formed. A housing; A fixing plate fixed to the LCD monitor by a bolt through the rotating member fixing hole, surrounding the cylindrical portion of the rotating shaft in parallel with the rotating shaft, a circular insertion portion inserted into the rotating member hole, and an end of the rotating shaft inserted therein. And a rotating shaft plate having a shaft groove having a greater resistance to external forces applied to the housing and the rotating member and bent at a perception from the fixed plate.

However, the hinge device of the two-stage configuration in which the housing and the rotating member are connected as described above has a very narrow width in the radius of rotation, and when the rotating member is used repeatedly for a long time, the supporting force for supporting the liquid crystal monitor is greatly reduced, so that the rotating member In addition to the trouble of having to replace and the loss of the bearing capacity of the rotating member was accompanied by the problem that even the expensive liquid crystal monitor is damaged, there is a problem that the production cost is increased by many components.

Moreover, in assembling the respective components, there is a problem in that work efficiency is greatly reduced and thus productivity is lowered as the components are not easily coupled.

The present invention has been made to solve the above problems of the conventional monitor hinge device, not only to smoothly rotate in the up / down direction of the monitor, but also to firmly rotate the monitor in a variable position thereof. It is possible to be fixed and to facilitate the installation of each component to improve the work efficiency to increase the productivity, and to form a wrinkle portion on one surface of the disk spring built on the rotary shaft which is the left / right rotation means of the monitor It is an object of the present invention to provide a hinge device for a monitor that enables the left and right rotation of the monitor to be doubled so that the left and right rotations of the monitor are smoothly performed.
