[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0019] like Figure 1-Figure 3As shown, the easily adjustable compression spring assembly installation structure in this portable DR includes a fixing seat 9 and a fixing rod 12. The fixing seat 9 is provided with a compression spring assembly, and the fixing seat 9 is installed in the column 15 by a screw 14. The fixing rod 12 is installed on the fixing seat 9, and the end of the fixing rod 12 is against the side wall of the column 15. The compression spring assembly includes a screw rod 10. The lower end of the screw rod 10 is threadedly connected to a nut 1 for adjusting the preload force of the compression spring assembly. The upper end of the screw rod 10 passes through the through hole in the middle of the fixing seat 9 and is connected to the chain 11. The upper end of the screw rod 10 also has an assembly positioning hole 10a. The fixing seat 9 is detachably provided with an assembly rod 13, and the assembly rod 13 can also be inserted into the assembly positioning hole 10a.

[0020] The fixing rod 12 can be detachably mounted on the fixing seat 9. The fixing rod 12 is a special-shaped rod. The column 15 has a special-shaped hole 15a that matches the fixing rod 12, and the fixing seat 9 has a special-shaped hole 2 9a that matches the fixing rod 12. There are two fixing rods 12, and the fixing rods 12 are arranged on both sides of the fixing seat 9 respectively.

[0021] The column 15 is provided with a rod-pulling hole 15 b for the assembly rod 13 to pass through, thereby facilitating the assembly and disassembly of the assembly rod 13 .

[0022] It can be assembled in advance outside the machine, and the assembly rod 13 is installed on the fixing seat 9 and inserted into the assembly positioning hole 10a at the upper end of the screw 10 to prevent the screw 10 from rotating. Then, the nut 1 at the lower end of the screw 10 is tightened to adjust the preload force of the spring 6. This technical solution facilitates the adjustment operation of the preload force of the spring 6.

[0023] Install the entire set of adjusted components into the column 15. After reaching the corresponding position, insert the fixing rod 12 into the column 15 and the fixing seat 9, and tighten the screw 14.
