Beneficial effect

The present invention adopts above-mentioned technical scheme, can bring following beneficial effect:

1. The angle-adjustable liquid crystal display bracket drives the upper cross rod and the lower cross rod to rotate by pressing the rotating block. The upper cross rod and the lower cross rod will drive the insertion rod to move out of the upper and lower card slots. When the display screen can drive the fixed block to move up and down on the surface of the support column, and the turntable can also rotate, and then drive the display screen to rotate in a circle to adjust the angle. At the same time, the fixed block can be rotated with the limit rod as the center of the circle, so that the insertion rod It can be inserted into the upper card slots arranged in an arc in the fixed block. At this time, the display screen can be turned back and forth as a whole and can stop at the position of each upper card slot, so as to meet most of the work needs of the staff.

2. The liquid crystal display bracket that is easy to adjust the angle will drive the fixed block to rotate when the display screen is turned over as a whole. The rotation of the fixed block will drive the airbag to rotate. The airbag will contact the top of the rotating plate, and then drive the rotating plate to rotate. The rotating plate will Push the slider to move, and the slider will push the extension board to move. At this time, the center of gravity of the support board can be moved to prevent the center of gravity from shifting after the display is turned over, which will cause the display to fall, so that the center of gravity can be transferred while the display is turned over. , thereby increasing the stability of the stent.

3. The liquid crystal display bracket that is easy to adjust the angle will contact the air bag when the display screen is turned over, the air bag will be squeezed and then blow out the gas, and the gas will be blown out through the air hole, and then can blow air to the cooling holes on the back of the display screen. In this way, the dust at the heat dissipation holes can be cleaned to prevent the dust from affecting the heat dissipation of the display screen. At the same time, the airflow can also promote the heat dissipation of the display screen and improve the heat dissipation effect.

4. The liquid crystal display bracket that is easy to adjust the angle, when the airbag is squeezed, it will push the push block to move. The push block pushes the slider to move through the screw rod and the sleeve, and the slider pushes the limit block to move through the slope of the surface. The limit block will drive the plugboard away from the inner wall of the clamping strip. At this time, the display screen can slide between the fixed block, so that after the display screen is turned over, the fixed block can still be located at the bottom of the display screen. The bristles are installed at the bottom, and when the fixing block slides on the display screen, the back of the display screen can be cleaned through the bristles, and the dust on the cooling holes can be further cleaned.

5. The liquid crystal display stand that is easy to adjust the angle, when the push block drives the screw rod to move, because the surface of the screw rod is provided with a spiral groove, and the inner wall of the sleeve has a block in the spiral groove, so the screw rod will move when it moves. Rotation occurs, and inside the slider, due to the gravity of the rectangular plate, the end of the elastic rod away from the screw rod will slide down the inner wall of the slider through the rectangular plate. At this time, the elastic rod will be inclined downward, and the rotation of the screw rod will Drive each elastic rod to rotate, and each elastic rod will rotate from one end close to the screw rod in a twist shape, and then squeeze the magnet to move to the other end. At this time, the magnet will move obliquely downward, and at the same time, the magnet will drive the magnetic plate to move downward. The downward movement of the magnetic plate will drive the push rod to move down, and the push rod will push the baffle to block the lower air hole, so that the air in the airbag can be blown out from the upper air hole, thereby increasing the cleaning of the dust at the heat dissipation holes, and the rotation of the elastic rod will Contact with the magnetic plate, and then generate vibration, which will promote the dust adhered to the surface of the bristles to fall off, and then realize the self-cleaning of the bristles.
