It is controlled by a motor to lift the equipment platform, which is safe and reliable; the balanced design ensures the level of the equipment platform and the safety of the equipment; the drive of the motor ensures the fast and effective operation of the equipment.

[0003] The retrieval in the authorization announcement number: CN220061168U discloses a rotary arm of a medical suspension tower, including a first cantilever. One side bottom end of the first cantilever is fixedly connected with a first fixed cylinder. The bottom of the first fixed cylinder is rotatably connected with a second cantilever. The second cantilever penetrates through a second fixed cylinder. A placement groove is formed on one side of the first fixed cylinder. A box body is fixedly installed in the placement groove. A driving mechanism is arranged on one side of the box body away from the first fixed cylinder. A trapezoidal block is arranged inside the box body; through the settings of the trapezoidal block, the slider, the connecting column, the sliding rod, and the fixing mechanism, the second cantilever can be fixed, avoiding the equipment hung by the second cantilever from moving during work, and improving the safe use performance of the medical suspension tower; through the setting of the anti-slip sleeve, the friction between the arc-shaped clamping plate and the second cantilever is increased, avoiding the equipment hung by the second cantilever from moving during work.

[0004] The above scheme can fix the second cantilever and avoid the equipment hung by the second cantilever from moving during work, but the length of its support arm is relatively fixed, and it is inconvenient to adjust the length of the support arm according to medical needs. Therefore, we propose an electric support arm of a medical suspension tower. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an electric support arm of a medical suspension tower, and by setting an adjustment unit and a fixing unit, to solve the problem that the length of the support arm is relatively fixed and it is inconvenient to adjust the length of the support arm according to medical needs.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An electric support arm of a medical suspension tower includes a main body unit, and further includes an adjustment unit arranged on the side of the main body unit, a fixing unit arranged below the main body unit, and a connecting unit arranged below the adjustment unit;

[0008] The adjusting unit includes a storage groove formed in the side wall of the main body unit, a support arm movably arranged in the storage groove, a gear groove formed at the bottom of the support arm, a fixing groove formed in the side wall of the support arm, a fixing column installed in the fixing groove, a gear seat installed on the circumferential side of the fixing column, a transmission member arranged below the adjusting unit, and a connecting spring with one end fixedly connected to the gear seat and the other end fixedly connected to the fixing groove;

[0009] The fixing unit includes a fixing seat installed at the bottom of the main body unit, an electric telescopic rod installed on the side wall of the fixing seat, a U-shaped seat installed at the telescopic end of the electric telescopic rod, a lead screw with opposite helix directions at both ends movably arranged inside the U-shaped seat, a clamping member arranged on the side of the lead screw, and a second driving motor installed at the input end of the lead screw.

[0010] Preferably, the main body unit includes a support seat, a first fixing cylinder installed on the top of the support seat, and a first cantilever installed inside the first fixing cylinder.

[0011] Preferably, the main body unit further includes an installation cylinder installed on the top of the first cantilever.

[0012] Preferably, the transmission member includes a first driving motor installed at the bottom of the support seat, and a cam installed at the output end of the first driving motor.

[0014] Preferably, the clamping member includes a moving member installed on the circumferential side of the lead screw, and an arc-shaped clamping plate installed on the side wall of the moving member.

[0015] Preferably, the fixing unit further includes a limit washer installed on the inner side wall of the U-shaped seat, and the limit washer is sleeved on the circumferential side of the lead screw.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the present utility model, through the provided adjusting unit and fixing unit, when it is necessary to adjust the support length according to medical needs, the first driving motor drives the cam to rotate by 90 degrees, releasing the clamping of the support arm by the gear seat. Subsequently, the length of the support arm inside the receiving groove can be pulled. When the distance between the support arm and the support seat adapts to the medical needs, the first driving motor drives the cam to continue rotating by 270 degrees, causing the gear seat to move upward to clamp the support arm, thereby realizing the adjustment of the support length according to medical needs. When the second cantilever needs to work, the telescopic end of the electric telescopic rod extends, driving the clamping member to approach the second cantilever through the U-shaped seat. Subsequently, the second cantilever drives the lead screw to rotate. Since the lead screw is provided with threads with opposite helix directions at both ends, the two clamping members move towards each other until the inner walls of the arc-shaped clamping plates are both in contact with the side walls of the second cantilever and then stop, thereby realizing the clamping and fixing of the second cantilever and preventing the second cantilever from moving during operation.
