Referring to fig. 1, in one embodiment, the rotating connecting assembly 10 further includes at least one first sealing ring 14 disposed between the first rotating sleeve 11 and the second rotating sleeve 12. Specifically, when the second rotating sleeve 12 is sleeved on the first rotating sleeve 11, the first sealing ring 14 is sleeved on the outer wall of the first rotating sleeve 11 and abuts against the inner wall of the second rotating sleeve 12. Therefore, on one hand, the first sealing ring 14 can ensure the sealing performance between the first rotating sleeve 11 and the second rotating sleeve 12, and prevent external dust and water from entering the wiring channel 13 through the gap between the first rotating sleeve 11 and the second rotating sleeve 12; on the other hand, the first sealing ring 14 can enable a damping force to exist in the rotation process between the first rotating sleeve 11 and the second rotating sleeve 12, so that the display screen 30 can rotate slowly and stably when the angle is adjusted through rotation.

Referring to fig. 1, further, when the first sealing ring 14 is sleeved on the outer wall of the first rotating sleeve 11, in order to ensure that the position of the first sealing ring 14 on the first rotating sleeve 11 is stable and cannot move along the axial direction, a first groove (not shown in the figure) adapted to the first sealing ring 14 is circumferentially disposed on the outer wall of the first rotating sleeve 11, and the first sealing ring 14 is disposed in the first groove. Of course, as an alternative, a first groove adapted to the first sealing ring 14 may also be provided circumferentially on the inner wall of the second rotary sleeve 12.

Specifically, the first fastener 18 includes, but is not limited to, a screw, a bolt, a threaded rod, a screw. In addition, the number of the first fastening members 18 is, for example, one, two, three or other number, and is not limited herein. So, first fastener 18 when tightening on spacing portion 16, first fastener 18 can make spacing portion 16 and the interval between the first step 111 reduce, first step 111 rotates the one end terminal surface in close contact with degree increase of cover 12 through first wear-resisting packing ring and second like this, spacing portion 16 rotates the damping force between the cover 12 through second wear-resisting packing ring and second step 121 in close contact with degree increase, thereby can increase first rotation cover 11 and second, be favorable to realizing that display screen 30 rotates slowly stably when rotating angle of adjustment. On the contrary, when the damping force between the first rotating sleeve 11 and the second rotating sleeve 12 is large, the first fastening member 18 is loosened on the limiting portion 16, so that the close contact degree of the first step 111 with the end face of one end of the second rotating sleeve 12 through the first wear-resistant gasket is reduced, the close contact degree of the limiting portion 16 with the second step 121 through the second wear-resistant gasket is reduced, and the damping force between the first rotating sleeve 11 and the second rotating sleeve 12 can be reduced.

Referring to fig. 1, in an embodiment, a first limiting member 112 is disposed on the first rotating sleeve 11, and a second limiting member 122 capable of limiting and matching with the first limiting member 112 is disposed on the second rotating sleeve 12. In this way, in the process of the mutual rotation between the first rotating sleeve 11 and the second rotating sleeve 12, when the first limiting member 112 and the second limiting member 122 are rotated to a predetermined angle, the first limiting member and the second limiting member are prevented from continuing to rotate relative to each other, so as to limit the rotation angle of the display screen 30.
