Description

Technical Field

[0001] The present application relates to the field of trolleys, and in particular to a rotating support arm with damping for a medical trolley. Background Art

[0002] A trolley refers to a carrier used to support equipment, such as a medical trolley, which is a vehicle body used to support various medical equipment, so as to facilitate medical staff to move and view various medical equipment. Some trolleys include a support arm, and the medical equipment or the equipment screen is installed on the support arm to facilitate the use of medical staff. When using the medical trolley, medical staff often need to rotate the equipment screen in the horizontal direction to adjust the direction of the equipment screen. However, most of the equipment screens on the support arms are prone to shaking due to inertia after rotation, or require a separate locking structure to re-fix the equipment screen, which has a complex structure and is inconvenient to operate.

[0012] Preferably, a rotation groove is provided on the side of the mounting seat, and one end of the cross arm away from the first connecting member is hinged in the rotation groove. A positioning hole is also provided on the cross arm, and a plurality of spring pins are also provided on the mounting seat. The spring pins are located on the moving trajectory of the positioning holes, and the spring pins are used to be inserted into the positioning holes to fix the cross arm.
