[0006] The column fixing portion is also provided with a window for operating the adjusting screw.

[0007] The upper end of the tension spring is connected to the upper connecting seat, and the pulley block is rotatably mounted on the upper connecting seat.

[0008] The column fixing part is rotatably connected to the base via a rotating disk, and the column fixing part is slidably connected to the column lifting part.

[0009] The locking nut and the adjusting screw are both hand-tightened structural parts.

[0010] In summary, the technical effects and advantages of the utility model are:

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1-Figure 3 As shown, the telescopic column balancing system of the mobile DR includes a tension spring 12 and a pulley block 13. The pulley block 13 is arranged at the upper end of the tension spring 12. It also includes an adjusting screw 8, a lower connecting seat 11 and a guide column 9. The lower connecting seat 11 is slidably connected to the column fixing part 4 through the guide column 9. One end of the adjusting screw 8 is movably connected to the column fixing part 4. In this embodiment, one end of the adjusting screw 8 and the column fixing part 4 are relatively free to rotate; the other end of the adjusting screw 8 is rotatably connected to the lower connecting seat 11, and the adjusting screw 8 is vertically arranged. A locking nut 10 is also threadedly connected to the adjusting screw 8, and the locking nut 10 can abut against the column fixing part 4.

[0020] The column fixing portion 4 also has a window 4 a for operating the adjusting screw 8 .

[0021] The upper end of the tension spring 12 is connected to the upper connecting seat 7 , and the pulley block 13 is rotatably mounted on the upper connecting seat 7 .

[0022] The column fixing part 4 is rotatably connected to the base 6 through the rotating disk 5, and the column fixing part 4 and the column lifting part 3 are slidably connected; in practice, the head assembly 1 is connected to the column lifting part 3 through the cross arm assembly 2; that is, the head assembly 1 is connected to the cross arm assembly 2, and the cross arm assembly 2 is connected to the column lifting part 3, and the column lifting part 3 is lifted and slid on the column fixing part 4. When in use, the operator will apply force on the handle on the head assembly 1 to lift or lower the column lifting part 3.

[0023] The locking nut 10 and the adjusting screw 8 are both hand-tightened structural parts.

[0024] There is a balancing part that drives the column lifting part 3 inside the column fixing part 4, and the driving force of the balancing part comes from the energy storage tension spring 12. Since the output force of the tension spring 12 will increase with the stretching length of the tension spring 12, a structure that can adjust the stretching length of the tension spring 12 is designed at the bottom of the tension spring 12 to adjust the output force of the tension spring 12; there is a window 4a at the bottom of the column fixing part 4 for easy adjustment, which is composed of an adjusting screw 8 and an adjusting guide column 9. There is a thread matching the adjusting screw 8 on the lower connecting seat 11 at the bottom of the tension spring 12. The lower connecting seat 11 at the bottom of the tension spring 12 and the adjusting guide column 9 can slide relative to each other. When the adjusting screw 8 tightens the tension spring 12, the guide column 9 can prevent the tension spring 12 from rotating around the axis. The guide column 9 can enhance the user's rigidity and linear control over the adjusting screw 8.

[0025] By turning the adjusting screw 8, the output force of the tension spring 12 can be adjusted, thereby adjusting the rising operating force and the descending operating force of the column lifting part 3, so that the rising operating force of the column lifting part 3 can be made smaller than the descending operating force; this will greatly improve the operating experience. At the same time, when the cross arm assembly 2 is unlocked and lifted, there will be an upward guiding force to guide the operator to unlock it smoothly. In addition, the energy storing tension spring 12 in the balancing part has the characteristics of fatigue and aging. After a period of use, the preset balancing effect can be achieved by tightening the tension spring 12. If the balancing force is appropriately increased in advance, it will be very helpful for the use cycle.

[0026] This telescopic column balancing system is used in mobile DR. Similarly, in practice, it can also be used in other equipment with telescopic columns that require balancing adjustment.

[0027] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0028] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
