[0004] However, the following problems were found in the implementation of the relevant technology: the current three-section lifting bollards are mostly used for the support and adjustment of medical facilities, so their stability is required. However, the above-mentioned three-section lifting bollard has certain shortcomings. It sets the threaded driving force in the middle, which causes the driving force of the first, second and third lifting cylinders to be concentrated in the middle, while the two sides are in an unused state. If the force is large, the two sides of the first, second and third lifting cylinders are prone to shaking, which will affect emergency medical rescue. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1 to 4As shown, this utility model provides a remote control device for a three-section lifting column in medical use, including a bottom lifting column 1, a first lifting column 4 slidably connected to the inner side of the bottom lifting column 1, a second lifting column 5 slidably connected to the inner side of the first lifting column 4, and a third lifting column 6 slidably connected to the inner side of the second lifting column 5. The bottom lifting column 1, the first lifting column 4, the second lifting column 5 and the third lifting column 6 are combined to form a multi-stage lifting column. A transmission component 2 is provided on the bottom lifting column 1, the first lifting column 4 and the second lifting column 5. A drive source 3 is connected to the inner side of the bottom end of the bottom lifting column 1, the inner side of the bottom end of the first lifting column 4 and the inner side of the bottom end of the second lifting column 5. The three drive sources 3 each have two power output ends, which facilitates providing driving force for multi-stage lifting adjustment. The surfaces of the three transmission components 2 are respectively connected to the power output ends of the three drive sources 3, so as to drive the first lifting column 4, the second lifting column 5 and the third lifting column 6 to adjust the vertical direction.
[0019] Specifically, the transmission assembly 2 includes six linkage rods 21 and six secondary bevel gears 23. Each pair of linkage rods 21 is connected to the power output end of each drive source 3. One end of each of the six linkage rods 21 is connected to a main bevel gear 22. The six secondary bevel gears 23 are meshed with the six main bevel gears 22, which facilitates the rotation of the secondary bevel gears 23 by the main bevel gears 22. The inner side of each of the six secondary bevel gears 23 is connected to an adjusting screw 24. The surface of each of the six adjusting screws 24 is threaded with an adjusting plate 25 through a screw nut.
[0020] Furthermore, the bottom ends of the two lower adjusting screws 24 are rotatably connected to the inner bottom end of the bottom lifting column 1 via bearings, the bottom ends of the two middle adjusting screws 24 are rotatably connected to the inner bottom end of the first lifting column 4 via bearings, and the bottom ends of the two upper adjusting screws 24 are rotatably connected to the inner bottom end of the second lifting column 5 via bearings, thereby improving the stability of the rotation of the adjusting screws 24.
[0021] Furthermore, the surfaces of the two lower adjustment plates 25 are connected to the surface of the first lifting column 4, the surfaces of the two middle adjustment plates 25 are connected to the surface of the second lifting column 5, and the surfaces of the two upper adjustment plates 25 are connected to the surface of the third lifting column 6, so as to facilitate the movement of the first lifting column 4, the second lifting column 5 and the third lifting column 6 through the corresponding adjustment plates 25.
[0022] It is worth noting that one side of the two lower adjustment plates 25 is in contact with the inner wall of the bottom lifting column 1, one side of the two middle adjustment plates 25 is in contact with the inner wall of the first lifting column 4, and one side of the two upper adjustment plates 25 is in contact with the inner wall of the second lifting column 5, which improves the stability of the adjustment of the lifting plates 25.
[0023] It is worth noting that the inner walls of the front and back of the bottom lifting column 1, the inner walls of the front and back of the first lifting column 4, and the inner walls of the front and back of the second lifting column 5 are all connected to limit rods 7. Limiting grooves 8 are provided on the front and back of the first lifting column 4, the front and back of the second lifting column 5, and the front and back of the third lifting column 6 to facilitate corresponding fit with the limit rods 7.
[0024] It is worth mentioning that the longitudinal section of each limiting rod 7 and the cross section of each limiting slide 8 are both rectangular, and the surface of each limiting rod 7 is slidably connected to the inner side of each limiting slide 8, which improves the stability of the movement of the first lifting column 4, the second lifting column 5 and the third lifting column 6.
[0025] The adjusting screw 24 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.
[0026] Working principle: First, it needs to be explained that the lower drive source 3 drives the first lifting column 4 for lifting adjustment, the middle drive source 3 drives the second lifting column 5 for lifting adjustment, and the upper drive source 3 drives the third lifting column 6 for lifting adjustment. Each of the three drive sources 3 drives the corresponding two adjusting screws 24 to rotate. Therefore, the operation of the lower drive source 3 is used as an example here; the middle and upper adjusting screws 24 operate similarly. When it is necessary to control the first lifting column 4 to extend from the bottom lifting column 1, the lower drive source 3 drives the corresponding two linkage rods 21 to rotate, thereby causing the corresponding main bevel gear 22 to drive the meshing secondary bevel gear 23 to rotate. This, in turn, drives the corresponding and symmetrical adjusting screws 24 to rotate, which in turn drives the two adjusting plates 25 and the first lifting column. 4. At this point, the vertical upward movement is achieved. Similarly, to drive the first lifting column 4 back into the bottom lifting column 1, the two linkage rods 21 can be reversed by the drive source 3. This is simple and quick, allowing the first lifting column 4 to extend or retract from the bottom lifting column 1. Providing symmetrical support to the first lifting column 4 helps improve the stability of its lifting adjustment. Similarly, the second lifting column 5 and the third lifting column 6 can be easily and quickly extended or retracted from the first lifting column 4. When the first lifting column 4 moves up or down, the limit rod 7 will slide against the corresponding limit groove 8, further improving the stability of the first lifting column 4's movement. The three independent drive sources 3 help meet the needs of local fine-tuning or emergency downgrading required for medical purposes.
