[0026] Example 1

[0027] An LED display device with adjustable viewing angle, such as Figure 1-4As shown, it includes: a display device body 20, a display screen 2 is arranged on one side of the top of the display device body 20, and a mounting seat 1 is fixed to one side of the display screen 2; a clamping block 4 is arranged on the end of the display device body 20 away from the mounting seat 1, and the clamping block 4 is U-shaped; a rotating wheel 3 is rotatably installed in the clamping block 4, and one side of the rotating wheel 3 is fixed to one side of the mounting seat 1; the rotation of the rotating wheel 3 in the clamping block 4 drives the mounting seat 1 to rotate, and then drives the display screen 2 to rotate accordingly with the rotating wheel 3; a support frame 11 is fixed to one side of the other end of the clamping block 4, and the support frame 11 is L-shaped; a first receiving strip 14 is arranged on one side of the top of the support frame 11, and the first receiving strip 14 is annular; a first anti-slip strip 13 is installed on the side of the first receiving strip 14 opposite to the display screen, and a first groove 19 is opened on the first anti-slip strip 13, and the first groove 19 is U-shaped; a first convex strip 21 is fixed to one side of the top of the display screen 2, and the first convex strip 21 is semi-cylindrical.

[0028] By providing the first anti-slip strip 13 and the first convex strip 21, when the display screen 2 is rotated at an upward angle, the rotation of the rotating wheel 3 in the clamping block 4 drives the mounting base 1 to rotate, and then drives the display screen 2 to rotate accordingly with the rotating wheel 3; and the first convex strip 21 at the top of the display screen 2 passes through the first anti-slip strip 13 when the display screen 2 rotates, providing a resistance that prevents the display screen 2 from rotating backward; at the same time, this arrangement can more conveniently position the display screen 2 upward at a certain angle to meet the needs of meetings.

[0029] In order to position the display screen 2 downward at a certain angle, a second supporting bar 16 is installed on the side of the support frame 11 facing the display screen 2, and the second supporting bar 16 is annular; a second anti-slip strip 17 is installed on the side of the second supporting bar 16 facing the display screen 2, and a second groove 15 is opened on the second anti-slip strip 17, and the second groove 15 is U-shaped; a second convex strip 5 is fixed to one side of the top of the display screen 2, and the second convex strip 5 is semi-cylindrical.

[0030] By providing the second anti-slip strip 17 and the second convex strip 5, when the display screen 2 is rotated at a downward angle, the rotation of the rotating wheel 3 in the clamping block 4 drives the mounting base 1 to rotate, and then drives the display screen 2 to rotate accordingly with the rotating wheel 3; and the second convex strip 5 at the top of the display screen 2 passes through the second anti-slip strip 17 when the display screen 2 rotates, providing a resistance that prevents the display screen 2 from rotating backward; at the same time, this arrangement can more conveniently position the display screen 2 downward at a certain angle to meet the needs of meetings.

[0031] In order to adjust the angle of the display screen to the left and right, a base 8 is installed at the bottom of the display device body 20, and a support seat 7 is fixed to one side of the upper end of the base 8, and the support seat 7 is cylindrical; a receiving column 10 is rotatably installed on the support seat 7, and the top end of the receiving column 10 is connected to one side of the bottom end of the support frame 11.

[0032] By setting the support base 7, the support base 7 not only plays a supporting role, but also provides a base that allows the display device body 20 to rotate left and right; the rotation of the receiving column 10 on the support base 7 drives the rotation of the support frame 11, and then drives the rotation of the display screen 2 to meet the needs of the meeting.

[0033] In order to prevent the display screen 2 from rotating randomly, a connecting strip 9 is fixed to one side of one end of the receiving column 10 , and an anti-slip ring 6 is connected to the other end of the connecting strip 9 . The anti-slip ring 6 is rotatably installed on one side of the outer periphery of the supporting seat 7 .

[0035] Working principle: when the display screen 2 is rotated at an upward angle, the rotation of the wheel 3 in the clamping block 4 drives the mounting base 1 to rotate, and then drives the display screen 2 to rotate accordingly with the wheel 3; and the first convex strip 21 at the top of the display screen 2 passes through the first anti-slip strip 13 when the display screen 2 rotates, providing a resistance that prevents the display screen 2 from rotating backward; at the same time, this setting can more conveniently position the display screen 2 at a certain angle upward to meet the needs of the meeting; when the display screen 2 is rotated at a downward angle, the rotation of the wheel 3 in the clamping block 4 drives the mounting base 1 to rotate, and then drives the display screen 2 to rotate accordingly with the wheel 3; and the second convex strip 5 at the top of the display screen 2 passes through the second anti-slip strip 13 when the display screen 2 rotates. The slide bar 17 provides a resistance that prevents the display screen 2 from rotating backwards; at the same time, this setting can more conveniently position the display screen 2 downward at a certain angle to meet the needs of the meeting; the support seat 7 not only plays a supporting role, but also provides a base that allows the display device body 20 to rotate left and right; the rotation of the receiving column 10 on the support seat 7 drives the rotation of the support frame 11, and then drives the rotation of the display screen 2 to meet the needs of the meeting; finally, the anti-slip ring 6 will rotate with the rotation of the receiving column 10 due to the action of the connecting strip 9; and the anti-slip ring 6 rotates on the outer side of the support seat 7, providing a rotation resistance to prevent the display screen 2 from being unable to be positioned when it rotates left and right and rotating at will, effectively meeting the needs of video conferencing.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
