Problems solved by technology
[0003] When the weight or type of the monitor changes or the weight of the swing arm changes or the energy storage spring ages and leaks, the joint arm does not have the function of rebalancing, and the hovering balance between the joint arm and the monitor is destroyed , it is necessary to replace the energy storage element or adjust the structure of the joint arm to maintain the effect of the display hovering at any position, and the maintenance of the joint arm is difficult
Since the energy storage element of the joint support arm is not adjustable, it is necessary to set joint support arms of different specifications according to different monitors, and the cost is high

The invention provides a supporting arm joint and a supporting arm. The supporting arm joint comprises a shell, a rotating piece and a main shaft connecting the rotating piece and the shell. A deceleration unit and an energy storage unit are mounted on the main shaft, the rotating piece is mounted on the deceleration unit, and the deceleration unit is used for reducing the torque transmitted by the rotating piece, and transmitting the reduced torque to the main shaft. The energy storage unit applies pretightening force to the main shaft so as to confront the torque borne by the main shaft, andthus the rotating piece can hover at any one swinging position. The deceleration unit can control the transmission ratio, and reduce the torque transmitted to the main shaft by a swinging arm according to the transmission ratio. The adjusting range of the energy storage unit is wide, the pretightening force can be adjusted according to the weight of different displayers or the swinging arm, and the hovering effect is good.
Description
technical field [0001] The application belongs to the technical field of medical equipment, and relates to an arm joint and an arm. Background technique [0002] Many ultrasound products are provided with a monitor mounted on a rotatably articulated arm. The articulated support arm is provided with a swing arm and an energy storage element. The energy storage element can be a spring or a gas spring. The weight of the display and the swing arm itself can be balanced by the energy storage element to achieve the effect of the display hovering at any position in the air. [0003] When the weight or type of the monitor changes or the weight of the swing arm changes or the energy storage spring ages and leaks, the joint arm does not have the function of rebalancing, and the hovering balance between the joint arm and the monitor is destroyed , It is necessary to replace the energy storage element or adjust the structure of the joint support arm to maintain the effect of the displa...
