[0035] See attached Figure 1 To Attachment Figure 5 , the figure shows a specific embodiment of a medical cart support arm provided by the utility model.
[0036] See attached Figure 1 and attached Figure 2 , Medical cart arm includes:
[0037] Active arm 1;
[0038] A turntable assembly 2 connected to one end of the movable arm 1, the turntable assembly 2 is used to carry an operating table;
[0039] The turntable assembly 2 comprises:
[0040] A fixed plate 210, the fixed plate 210 is connected to the movable arm 1;
[0041] A rotating disk 220 disposed on the fixed disk 210, and the rotating disk 220 can rotate relative to the fixed disk 210;
[0042] The de-energized electromagnet 230 and the magnet suction piece 240 are arranged between the fixed disk 210 and the rotating disk 220. When the de-energized electromagnet 230 is powered off, the de-energized electromagnet 230 adsorbs the magnet suction piece 240 to prevent the rotating disk 220 from rotating. When the de-energized electromagnet 230 is powered on, the de-energized electromagnet 230 loses its magnetic force to enable the rotating disk 220 to rotate.
[0043] See attached Figure 2 In the above embodiment, the movable arm 1 is connected to the turntable assembly 2, the turntable assembly 2 is used to support the operating table of the medical device, the movable arm 1 is used to adjust the height, and the turntable assembly 2 is used to adjust the angle. When the rotating disk 220 of the turntable assembly 2 is placed on the medical device, the rotation of the medical device is achieved by the relative rotation between the rotating disk 220 and the fixed disk 210. In the embodiment, the power-off electromagnet 230 and the magnet suction sheet 240 are fixedly arranged on the rotating disk 220 and the fixed disk 210, respectively. When the power-off electromagnet 230 is not powered, the power-off electromagnet 230 has a magnetic attraction force, and the magnet suction piece 240 is attracted to make the rotating disk 220 and the fixed disk 210 relatively locked, so that the rotating disk 220 cannot rotate, that is, the medical device placed on the rotating disk 220 cannot rotate; when the power-off electromagnet 230 is powered, the power-off electromagnet 230 loses its magnetic attraction force, and the power-off electromagnet 230 and the magnet suction piece 240 are no longer attracted to each other, so that the rotating disk 220 and the fixed disk 210 can rotate relatively, so that the rotating disk 220 can be rotated, that is, the medical device placed on the rotating disk 220 can be rotated. This embodiment adopts the design of the turntable assembly 2 combining the power-off electromagnet 230 and the magnet suction piece 240, so as to realize the locking and rotation of the turntable assembly 2 by controlling the power-on and power-off state of the power-off electromagnet 230, which is simple to operate and convenient to use.
[0044] See attached Figure 3 and attached Figure 4 In the above embodiment, the de-energized electromagnet 230 is disposed at the lower end of the rotating disk 220, and the magnetic suction piece 240 is disposed at the upper end of the fixed disk 210. In an optional embodiment, the positions of the de-energized electromagnet 230 and the magnetic suction piece 240 can be exchanged.
[0045] See attached Figure 2 In the above embodiment, a suction sheet groove 211 is provided near the edge of the upper end of the fixing plate 210, and the shape of the suction sheet groove 211 is adapted to the shape of the magnet suction sheet 240, and the magnet suction sheet 240 is installed in the suction sheet groove 211. In the embodiment, the suction sheet groove 211 is used to place the magnet suction sheet 240, and the magnet suction sheet 240 is confined in the suction sheet groove 211. In this embodiment, the suction sheet groove 211 is arc-shaped, and the magnet suction sheet 240 is also arc-shaped.
[0046] See attached Figure 2In the above embodiment, an elastic member 250 is provided in the suction plate groove 211, and the elastic member 250 is located between the bottom of the suction plate groove 211 and the magnet suction plate 240, so that the magnet suction plate 240 abuts against the power-off electromagnet 230. In the embodiment, the depth of the suction plate groove 211 is greater than the thickness of the magnet suction plate 240. In order to prevent the magnet suction plate 240 from breaking away from the magnetic suction state and falling to the bottom of the suction plate groove 211 when the power-off electromagnet 230 is powered on, causing a sound, or the magnet suction plate 240 is quickly adsorbed on the power-off electromagnet 230 and makes a sound when the power-off electromagnet 230 is powered off, in this embodiment, by providing an elastic member 250 between the bottom of the suction plate groove 211 and the magnet suction plate 240, under the elastic force of the elastic member 250, the magnet suction plate 240 abuts against the power-off electromagnet 230, regardless of whether the power-off electromagnet 230 is powered on, the magnet suction plate 240 in the abutting state will never make an abnormal sound, thereby improving the user experience. In this embodiment, the elastic member 250 is a spring.
[0047] See attached Figure 4 In the above embodiment, a plurality of guide posts 2111 are provided at the bottom of the suction sheet slot 211, a plurality of guide holes 241 are provided on the magnet suction sheet 240, and the elastic member 250 is sleeved on the guide posts 2111, and the guide holes 241 correspond to the guide posts 2111. In the embodiment, the guide posts 2111 are vertically arranged to facilitate the installation of the elastic member 250 during assembly. At the same time, the guide posts 2111 and the guide holes 241 cooperate to limit the moving direction of the magnet suction sheet 240, prevent the magnet suction sheet 240 from shaking in the suction sheet slot 211, and improve the structural stability.
[0048] See attached Figure 2 In the above embodiment, a notch 212 is provided at the edge of the fixed disk 210, the suction plate groove 211 is sunken in the notch 212, and stop surfaces 2121 are formed on both sides of the notch 212. The lower end of the power-off electromagnet 230 is movably placed in the notch 212. In the embodiment, the top of the power-off electromagnet 230 is fixedly mounted to the lower end of the rotating disk 220, and the bottom part of the power-off electromagnet 230 protrudes and is placed in the notch 212. When the rotating disk 220 rotates, the bottom end of the power-off electromagnet 230 moves in the notch 212 area. Since the stop surfaces 2121 are formed on both sides of the notch 212, the existence of the stop surfaces 2121 limits the range of movement of the power-off electromagnet 230, thereby also limiting the angle at which the rotating disk 220 can be rotated.
[0049] See attached Figure 2 In the above embodiment, the turntable assembly 2 further includes a bearing 260, which is installed at the axis between the fixed disk 210 and the rotating disk 220. In the embodiment, one end of the bearing 260 is fixed to the fixed disk 210, and the other end is fixed to the rotating disk 220, so that the rotating disk 220 can rely on the bearing 260 to achieve relative rotation with the fixed disk 210.
[0050] See attached Figure 3 and attached Figure 5 In the above embodiment, the movable arm 1 includes a fixed connection head 110 and a movable connection head 120, and an upper connecting rod 130 and a lower connecting rod 140 disposed between the fixed connection head 110 and the movable connection head 120, and the movable connection head 120 is connected to the bottom end of the fixed plate 210. In the embodiment, the fixed connection head 110, the movable connection head 120, the upper connecting rod 130, and the lower connecting rod 140 together form a parallelogram structure, and the connection points between the two are rotatable, so that the upper connecting rod 130 and the lower connecting rod 140 can swing relative to the fixed connection head 110, so that the movable connection head 120 located at the opposite end of the fixed connection head 110 can achieve height adjustment.
[0051] See attached Figure 3 and attached Figure 5 In the above embodiment, a push rod 150 is further provided between the upper connecting rod 130 and the lower connecting rod 140. The fixed end of the push rod 150 is installed in the fixed connector 110 and is close to the lower connecting rod 140. The movable end of the push rod 150 is connected to the upper connecting rod 130 and is close to the movable connector 120. In the embodiment, when the movable end of the push rod 150 is extended, the upper connecting rod 130 and the lower connecting rod 140 swing upward, the height of the movable connector 120 is increased, and the height of the turntable assembly 2 is increased, thereby increasing the height of the operating table; when the movable end of the push rod 150 is retracted, the upper connecting rod 130 and the lower connecting rod 140 swing downward, the height of the movable connector 120 is reduced, and the height of the turntable assembly 2 is reduced, thereby reducing the height of the operating table; by changing the extension and retraction of the movable end of the push rod 150, the height adjustment of the operating table is achieved.
[0052] See attached Figure 3 and attached Figure 5 In the above embodiment, the push rod 150 is an electric push rod or a gas spring.
