In this case, the third rotary gear 173 may be connected such that the second cross gear 174 has a rotation direction opposite to that of the first cross gear 162.

A safety means 180 may be installed between the motor 150 and the first rotary gear 161 provided to receive the rotational power of the motor 150 for the first time. The safety means 180 is the first rotating gear 161 by idling the motor 150 when a predetermined external pressure is applied by obstacles such as a person or an object when the support frames 121 and 122 rotate.

In addition, the present invention may be provided with a microcontroller (not shown) for driving control of the motor 150 and a remote controller (not shown) designed to transmit a control signal to the microcontroller.

Referring to the operation of the display panel mounting and rotation control device 100 according to the present invention made of such a configuration as follows.

In the state in which the display panel 2 is mounted on the mounting bracket 104, a pin is connected to the connection plate 102 positioned on the reference plane 1 through a fixing bracket 101 fastened to the reference plane 1 such as a wall. When the mounting bracket 104 is fastened through a coupling means such as a coupling, the display panel 2 can be mounted on a wall.

At this time, since the mounting bracket 104 is pin-connected with the connection plate 102 side, the display panel 2 tries to form a slope in its own weight, as shown in FIG. 3, a stopper disposed on the mounting bracket 104. 106 is supported by the support frame 122 coupled to the pivot rod 110 to limit the tilt so that the display panel 2 is horizontal with respect to the reference plane 1 when the display panel 2 is initially mounted. To be installed and maintained as is.

In the initial mounting state of the display panel 2, the display panel 2 is mounted horizontally with respect to the reference plane 1, and the rotary vanes 140 are folded and connected as shown in FIG. The plate 102, the mounting bracket 104, and the display panel 2 are disposed in close contact with the support frames 121 and 122 and the reference plane 1.

When the control signal of the rotation operation is generated to the device through the remote controller for the rotation adjustment of the display panel 2, the control signal is transmitted to the microcontroller and drives the motor 150.

When the clockwise rotation (right turn) of the motor 150 is performed, the same rotational force is transmitted to the first rotary gear 161, and the first cross gear 162 perpendicularly intersected thereto may also rotate clockwise.

As the first cross gear 162 rotates, the first idler 131 axially coupled thereto rotates right, and as shown in FIG. 5, the rotary blade 140 coupled to the first idler 131 performs a right turn. While the connecting plate 102 is rotated in the right direction forward movement is made.

Here, the second idler 132 is also guided to rotate in the same direction while the connecting blade 102 is rotated and moved forward through the rotary blade 140 coupled to it, thereby connecting the connection plate 102 and the mounting bracket The 104 and the display panel 2 are led away from the reference plane 1.

In this case, as the first and

second idlers

131 and 132 and the rotary blades 140 function by the power transmission by the motor 150, they are coupled to the rear end of the mounting bracket 104 to refer to the display panel 2. As shown in FIG. 4, the stopper 106, which has been supported in a horizontal state with respect to (1), releases the support force with the support frame 122, and thus the display panel 2 forms a constant inclination due to its own weight. In this state, a rotation operation for the swivel is made.

In addition, the rotational force of the first cross gear 162 is transmitted to the second rotation gear 172 to induce rotational force in the counterclockwise direction (left rotation), and to the third rotation gear 173 through the shaft 171. Delivered.

Here, the second cross gear 174 is connected to the pivot shaft 107, and the pivot shaft 107 is fixed to the fixing bracket 101. Since the second cross gear 174 is fixed, the third rotary gear 173 rotates around the axis of the second cross gear 174 as the third rotary gear 173 rotates in engagement with the second cross gear 174. As a result, the second cross gear 174 is rotated. As the third rotary gear 173 rotates about the axis of the second cross gear 174, the shaft 171 connected to the third rotary gear 173 also rotates about the axis of the second cross gear 174. Therefore, the pivot rod 110 attached to the support frames 121 and 122 and the support frames 121 and 122 to which the shaft 171 is fixed is also the axis of the second cross gear 174, that is, the covering shaft. It will rotate about 107. At this time, the pivot rod 110 is a bearing coupled to the pivot shaft 107 can be rotated in accordance with the rotation of the

support frame

121, 122 around the fixed pivot shaft 107.

Accordingly, as shown in FIG. 5, the direction and the screen switching of the display panel 2 can be performed through the apparatus 100 of the present invention.

Contrary to the above, if the motor 150 is rotated in the counterclockwise direction, the operation is performed in the reverse direction of the above-described operation, and the operation can be performed up to the initial installation state.

On the other hand, the safety means 180 provided in the device 100 of the present invention is applied to the braking force by the frictional pressure when a certain pressure or more external pressure is applied by the locking by an obstacle such as a person or an object during the swivel operation of the device The motor 150 is idling and the rotational force of the motor 150 is not transmitted to the first rotary gear 161.

That is, when an external pressure is applied to the device 100 of the present invention by a human or object, the plate spring washer 184 presses the friction plate 183 by the external pressure and friction to the friction plate 183 By maximizing the generation, it induces idling of the motor 150 and stops only the rotational motion of the swivel with respect to the apparatus 100.

At this time, if the external pressure is released on the device or the rotational power of the motor 150 is greater than the external pressure, the motor 150 continues to perform the rotation operation of the device.

It can be used in all industries of manufacturing and using display panel holders.
