In this example, the inner diameter of the fixing ring 11 matches the inner diameter of the supporting cylinder 12. Specifically, the inner diameter of the fixing ring 11 is consistent with the inner diameter of the supporting cylinder 12. In this example, the base cylinder is concentrically welded with the fixing ring.

[0033] The fixing ring 11 is provided with a fixing hole 111, and the fixing seat 1 is fixed to the site where the measuring grating is to be installed by the cooperation of the screw and the fixing hole 111.

[0036] In the present application, the inner diameter of the adjusting sleeve 21 matches the outer diameter of the supporting cylinder 12. It should be noted that the inner diameter of the adjusting sleeve 21 matches the outer diameter of the supporting cylinder 12. Specifically, the inner diameter of the adjusting sleeve 21 matches the outer diameter of the supporting cylinder 12.

[0037] The matching is consistent, or the inner diameter of the adjusting sleeve 21 is slightly larger than the outer diameter of the supporting cylinder 12.

[0038] The adjusting sleeve 21 is provided with an adjusting hole 211 and an adjusting bolt 212 matching the adjusting hole 211.

Those skilled in the art can set the size of the groove according to actual needs, which all belong to the protection scope of the present application. During specific use, the detection bracket 4 is fixed in the mounting groove 221, and then the measuring grating is installed on the detection bracket 4, so as to realize that the measuring grating is fixed in the cold rolling mill measuring grating installation protective device of the present application. It should be noted that the detection bracket 4 is a commonly used device in this field, Figure 6 This is a schematic diagram of the structure of a commonly used detection bracket. Therefore, the structure of the detection bracket 4, the process of fixing the detection bracket 4 in the installation groove 221, and the process of installing the measuring grating on the detection bracket 4 will not be described in detail here.

[0042] The support disc 22 also has a wire hole 222 . When in use, the cable of the measuring grating passes through the wire hole 121 and the wire hole 222 in sequence to be connected to the measuring grating.
