During the treatment of blood purification equipment, medical staff need to pay attention to the treatment data on multiple patients and multiple equipment displays at the same time, but the fixed display on the equipment is not convenient for medical staff to observe the treatment data of the patient, and the labor intensity of medical staff is relatively high.

[0003] To this end, a Chinese patent discloses a blood purification equipment display rotation positioning mechanism [authorization announcement number is CN208927214U], including a display, on which a rotating support is fixed, a fixed seat is arranged below the rotating support, the fixed seat is rotatably connected to the rotating support, and mutually cooperating limiting structures are provided on the fixed seat and the rotating support.

[0015] In the above display flipping mechanism, an end cover is provided on the outer side of the connecting flange.

[0016] The end cover protects each component and plays a role in dust prevention. At the same time, it cooperates with the first sealing ring to achieve a waterproof effect.

[0020] In the above display flipping mechanism, the base is provided with an arc-shaped second limiting groove, the shaft body is provided with a second limiting column extending into the second limiting groove, and the second limiting column and the second limiting groove are used to limit the left and right rotation angle of the display.

[0021] The second limiting groove extends in an arc shape along the center line of the rotating shaft, and the second limiting column is fixed on the rotating shaft body, limiting the left and right rotation range of the display to 0-120°.

[0022] In the above display flipping mechanism, a second sealing ring is provided between the rotating body and the base.

[0024] Since the connecting flange is rotatably sleeved on the positioning shaft, the display can be flipped up and down around the positioning shaft, and the first damping structure is used to keep the display at the current position. When the rotating shaft body rotates, the rotating shaft is driven to rotate in the rotating hole, so that the left and right angles of the display are changed, which can fully meet the use needs of medical staff; the overall assembly is convenient, the damping of flipping and rotation can be adjusted, and it can effectively prevent dust and water.
